Yet the dry ice blasting major part still is applied in industrial cleaning aspect, really is used in the food hygiene aspect and also has a lot of limitation.
Summary of the invention
In order to solve above technical problem, the objective of the invention is to: a kind of Dry ice cleaning device and cleaning method thereof are provided.Said Dry ice cleaning device and cleaning method thereof are specially adapted to the food hygiene field.
For achieving the above object, Dry ice cleaning device technique scheme of the present invention is:
A kind of Dry ice cleaning device; Comprise air compression system and the spraying system that is communicated with it; Said air compression system comprises air compressor and is communicated with, moves towards separately gases at high pressure pipeline and the low-pressure gas pipeline of post-concentration in spraying system respectively with it, it is characterized in that
On the said low-pressure gas pipeline feeding distribution mechanism and pressure-reducing valve are set, said gases at high pressure pipeline adopts venturi nozzle, and said air compression system is communicated with Venturi nozzle in the said spraying system through venturi nozzle;
The said feeding distribution mechanism port of export is connected with the end of venturi nozzle in the said air compression system, and links to each other with said spraying system.
According to Dry ice cleaning device of the present invention, be preferably, the dry ice material tube inner wall in the said feeding distribution mechanism is provided with thermal insulation layer.
The bottom of the dry ice barrel in the feeding distribution mechanism is equipped with tripper, connects with the low-pressure gas pipeline through three-way connection again.Owing to have pressure in the pipeline, can from barrel, get into low pressure pipeline smoothly for making dry ice, in the barrel certain pressure should be arranged, we select for use threeway that one road low-pressure gas is inserted in the barrel.Therefore, barrel should be a pressure vessel.Can from surrounding environment, absorb a large amount of heat during dry ice sublimation, therefore, material tube inner wall should have thermal insulation layer.
According to Dry ice cleaning device of the present invention; Be preferably; Said spraying system comprises that spray gun, Venturi nozzle, mixing chamber and dry ice particles transmission are used and dual circuit is used in the pressure-air transmission; The said feeding distribution mechanism port of export and said venturi nozzle end are communicated in the said mixing chamber, and above-mentioned dry ice particles transmission is used and the pressure-air transmission is connected with the port of export and the said venturi nozzle of said feeding distribution mechanism respectively with dual circuit.
According to Dry ice cleaning device of the present invention, be preferably, dry ice particles of the present invention transmission with and the pressure-air transmission with dual circuit in, dry ice is carried by the low-pressure gas pipeline.
The pipe-line system of Dry ice cleaning has single flexible pipe and two kinds of two hose.When single flexible pipe was worked, pressure-air and dried dry ice particles were mixed in one, produce continuous specified ice stream (high efficient, high pressure), and its production cost is high, and maintenance load is big, were suitable for the high pressure transfer system of working energetically the ice stream amount; In two flexible pipes (Fig. 2) when work,, dry ice particles and pressure-air in two flexible pipes, are applicable to the low pressure transfer system of low dry ice flow respectively before the ejection gun barrel, have the advantage that ice consumes less, use cost is low.
In dual circuit of the present invention system, because the length of dry ice is wide greater than nozzle, so the mode that the dry ice spray gun will adopt dry ice to mix with high-speed gas quickens, and mixes the mode of acceleration again with gases at high pressure unlike sand-blasting machine that kind abrasive material.
According to Dry ice cleaning device of the present invention, be preferably, the tripper in the said feeding distribution mechanism is a leaf structure.
According to Dry ice cleaning device of the present invention, be preferably, the diameter of said Venturi nozzle is 3-7mm.
The industry shot-peening cleans the nozzle uses and is Venturi nozzle, calculate and put into practice all shown Venturi nozzle than normal straight tube nozzle under identical operating mode, jet velocity is higher, cleaning performance is better, shot-peening is more even.Usually shot-peening uses nozzle diameter to be 9.5mm or 11.1mm, and nozzle is big more, and it is big more that the capacity of air compressor machine also requires, and the consumption of abrasive material (dry ice) is also big more.Therefore consider that air compressor machine capacity and operating pressure and dry ice consume quantitative limitation, we choose the nozzle of 3-7mm.
Different with industrial shot-peening cleaning is; Dry ice particles is diameter 3mm; The cylinder of length 2.5～10mm; The industry shot-peening cleans used abrasive size and generally is lower than 0.2mm, so dry ice particles can't be through the nozzle of 3-7mm, this just Dry ice cleaning never have one of reason of miniaturization---the contradiction between the dry ice particle diameter limits nozzle with the air compressor machine capacity the requirement of jet size.
For achieving the above object, the technical scheme of dry ice cleaning method of the present invention is:
Adopt a kind of like this Dry ice cleaning device; Comprise air compression system and the spraying system that is communicated with it; Said air compression system comprises air compressor and is communicated with, moves towards separately gases at high pressure pipeline and the low-pressure gas pipeline of post-concentration in spraying system respectively with it; On the said low-pressure gas pipeline feeding distribution mechanism and pressure-reducing valve are set, said gases at high pressure pipeline adopts venturi nozzle, and said air compression system is communicated with Venturi nozzle in the said spraying system through venturi nozzle;
The said feeding distribution mechanism port of export is connected with the end of venturi nozzle in the said air compression system, and the said feeding distribution mechanism port of export links to each other with said spraying system with terminal connection place of said venturi nozzle,
This method is to improve air pressure through air compressor; Then increase substantially jet velocity through venturi nozzle; Form negative pressure at the mixing nozzle place, with the dry ice particles sucking-off feeding distribution mechanism of 2-4mm through shower nozzle with after high-speed air fully mixes, be ejected into material surface; Make dry ice particle impact distillation rapidly behind the thing to be cleaned surface, realize cleaning.
Dry ice cleaning can not damaged material surface.Dry ice cleaning system can be according to user's needs; Dry ice preparation system and dry ice blasting system support fitted together as a cover system use. also can the dry ice preparation system be separated with the dry ice blasting system; Just as the production equipment of supplying raw materials, the dry ice blasting system is used to clean engineering separately to the dry ice preparation system.The dry ice particles of 2-4mm can be bought from market and obtain, or uses dry ice particles manufacturing machine to be power source through compressed air, will be made into liquid CO 2 the particle of 2-4mm.
Dry ice clean technologies principle is to make different material under different contraction speeds, produce disengaging with temperature difference physical reactions; The surface adhesion thing can be cooled and the catalysis explosion simultaneously, produces " little gas explosion " stripping usefulness with 800 times of volume instantaneous expansion after compressed air stream and the dry ice gasification again.This temperature difference physical reactions is to disperse to absorb treatment surface heat energy with the air pressure acceleration dry ice to make its rapid contraction and tear disengaging to the unstructuredness connection, and the bigger generation temperature difference of air pressure reflects that the fast effect that heals heals obviously.Or still locate high temperature following time when working surface, and use dry ice blasting, it is even more ideal then can to produce bigger temperature difference effect.
According to above-mentioned, the present invention be with the dry ice particles of Manufactured 3mm through with the mixing of high-speed gas after, the surface that bump needs to clean forms little gas explosion, spot " is blown up " thus reach the purpose that washes the dishes.
System utilizes the compressed air of the compressed air system generation of self preparing. the dry ice particles of in cleaning device, packing into and having made; Under compressed-air actuated driving; High density dry ice particles or fine powder are cleaned body surface along with compressed air impacts, thereby play cleaning action.
The dry ice cleaning method according to the present invention, said dry ice blasting speed Mach value is between 1.7-3.0.
The kinetic energy of winding-up is primary condition, and this depends primarily on the pressure of air, can increase substantially speed through venturi nozzle simultaneously and increase kinetic energy.Dry ice particles is contained in the container of sealing, can uniform distribution dry ice supply through feeding distribution mechanism.Dry ice particles is mixed, is quickened with air through conveyance conduit, sprays from nozzle.Jet velocity Mach value is usually between 1.7-3.0. and concrete numerical value depends on design and air pressure.
According to schematic diagram of the present invention; The gases at high pressure that come out by compressor are divided into two-way; One the tunnel drives dry ice particles through decompressor decompression back arrives nozzle, and another road gas reaches through Venturi nozzle earlier and sprays required speed and arrive the nozzle place, simultaneously high-speed gas the nozzle place form negative pressure to pipeline in dry ice have suction to send effect; Low pressure dry ice air-flow and high-speed air flow fully mix the back ejection at the nozzle place like this, clean.
In dry ice cleaning method of the present invention, as be used in family cleaning aspect, said air compressor machine pressure is controlled at 0.5～0.8MPa.
The used air compressor machine pressure of present industrial shot-peening wiper mechanism is at 0.5～1.0MPa, and domesticly is used for the air compressor machine that shot-peening cleans and is mostly 0.6～0.8MPa, and capacity is usually at 4m
3More than, be lower than 4m
3Generally regarded as small air compressor, in industry is cleaned, avoided the use of usually.The practical experience of long-term accumulation shows that the capacity of air compressor machine is preferably about 1.5 times of nozzle air consumption, so just can give full play to the effect that shot-peening cleans.Yet through our investigation, the air compressor machine that capacity is 1 cube is just very heavy, wants to be implemented in the small-sized cleaning device that uses in the home-ranges, at first will be the volume controlled of air compressor machine in average family acceptable scope.
Air compressor machine the time can produce the noise that arrives very much in work, and is very ear-piercing, but after the operating pressure of air compressor machine reduced, noise reduced rapidly, therefore for making things convenient for family's use, the pressure of air compressor machine fixed on 0.5～0.8MPa, if reduction will influence cleaning performance again.
The dry ice cleaning method according to the present invention is preferably, and said pressure piping pressure is at 0.55-0.65MPa, and low pressure pipeline pressure is 0.13-0.25MPa.
Huge in the shot-peening cleaning process to compressed-air actuated demand; If be used to carry the pressure of low pressure pipeline of dry ice too high, though the conveying capacity of gas improves, corresponding gas flow also can strengthen; Cause gas deficiency in the pressure piping; Compressed Gas can't fully quicken, and then dry ice can not can not be reached the cleaning purpose of expection by abundant acceleration.
For pressure piping, receive the restriction of air compressor machine capacity equally.In addition, if the hypertonia of pressure piping has not only reduced the conveying capacity of low pressure pipeline, simultaneously too high pressure can produce the noise of shrillness when quickening, destroyed the cleaning environment greatly.
Analysis more than comprehensively, pressure piping pressure tentatively fixes on 0.55-0.65MPa, and low pressure pipeline pressure tentatively is decided to be 0.13-0.25MPa.In test, when low pressure a little less than 0.15MPa, cleaning performance is best, has both satisfied the requirement of carrying dry ice particles, can not have much impact to pressure duct again.
According to dry ice cleaning method of the present invention, be preferably, the dry ice particles per minute consumption of nozzle is 35-45g.
According to dry ice cleaning method of the present invention, be preferably, the dry ice material tube inner wall in the said feeding distribution mechanism is provided with thermal insulation layer.
The bottom of the dry ice barrel in the feeding distribution mechanism is equipped with tripper, connects with the low-pressure gas pipeline through three-way connection again.Owing to have pressure in the pipeline, can from barrel, get into low pressure pipeline smoothly for making dry ice, in the barrel certain pressure should be arranged, we select for use threeway that one road low-pressure gas is inserted in the barrel.Therefore, barrel should be a pressure vessel.Can from surrounding environment, absorb a large amount of heat during dry ice sublimation, therefore, material tube inner wall should be established thermal insulation layer.
In dual circuit of the present invention system, because the length of dry ice is wide greater than nozzle, so the mode that the dry ice spray gun will adopt dry ice to mix with high-speed gas quickens, and mixes the mode of acceleration again with gases at high pressure unlike sand-blasting machine that kind abrasive material.
According to dry ice cleaning method of the present invention, be preferably, the tripper in the said feeding distribution mechanism is a turbo blade formula structure.
According to dry ice cleaning method of the present invention, be preferably, the diameter of said Venturi nozzle is 3-7mm.
The industry shot-peening cleans the nozzle uses and is Venturi nozzle, calculate and put into practice all shown Venturi nozzle than normal straight tube nozzle under identical operating mode, jet velocity is higher, cleaning performance is better, shot-peening is more even.Usually shot-peening uses nozzle diameter to be 9.5mm or 11.1mm, and nozzle is big more, and it is big more that the capacity of air compressor machine also requires, and the consumption of abrasive material (dry ice) is also big more.Therefore consider that air compressor machine capacity and operating pressure and dry ice consume quantitative limitation, we choose the nozzle of 3-7mm.
The present invention separates air hose and two pipelines of dry ice pipe through the pipe-line system of design different pressures, and dry ice will be carried by special low-pressure gas pipeline, separate introducing with gases at high pressure, can increase substantially speed through venturi nozzle simultaneously and increase kinetic energy.In the spraying system part, the mode that the dry ice spray gun will adopt dry ice to mix with high-speed gas is quickened, and makes jet velocity faster, and cleaning performance is better.Simultaneously, also with industrial Dry ice cleaning equipment miniaturization, make it can be used for family food hygiene field.
Advantage of the present invention is:
(1) conserve water resource.Utilize solid dry ice particles and high-speed gas to clean, the complete unfavorable water of cleaning process has fundamentally reduced the phenomenon that common cleaning technique causes a large amount of wastes of water resource, effectively protects, practiced thrift water resource.
(2) no cleaning agent is residual.Because the bowl to spot is arranged directly cleans, so can raise the efficiency; Owing to need not clear up, reduce running cost to residual cleaning agent; No cleaning agent residual, thereby equipment do not caused a hidden trouble.
(3) human body and environment are not produced harm and pollution.Utilized the waste gas carbon dioxide, reduced the discharging of greenhouse gases, to zero environmental, especially dry ice has avirulence, and this is that other cleaning agents are incomparable.
(4) do not wear and tear and be cleaned thing surface surface.The unique distinction of Dry ice cleaning is that dry ice particles is in impact moment gasification.The momentum of dry ice particles is impacting pop-off.Heat exchange takes place rapidly between dry ice particles and clean surface.Cause dry ice, distillation becomes gas rapidly.Dry ice particles expands nearly 800 times in some thousandths of inner volume second.So just cause miniature blast at shock point.Because dry ice particles distillation becomes gas, and dry ice particles was merely for 1 second by distillation time of solid-state change gaseous state, thus the short time effect down dry ice particles basically can not cause any infringement to the surface of cleaning thing.
(5) has sterilizing function.Because the dry ice particles temperature only has-78.5 ℃, under low like this environment temperature, most of bacterium and virus all can't be survived, the complete like this purpose that can reach sterilization, and because clean and sterilize be carry out simultaneously so also improved overall efficiency.
