The present invention is cooled down to the gaseous state freon of high temperature using the cold air after evaporator dry, saves the fan in condensing units or condensed water, changes tradition and relies on cooling fan or the type of cooling of cooling water, saves members, saved the energy simultaneously.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
The saturation moisture content of compressed air is relevant with temperature, and during temperature drop, water content also declines.Pressure before assuming to enter exsiccator is 0.7mpa, 40 DEG C of temperature, then the water content of per kilogram is about 5.7874 grams；To 3 DEG C, the aqueous tolerance of compressed air is about 0.5899/kg for temperature drop.One kilogram of compressed air, when dropping to 3 DEG C for 40 DEG C, there are about 5.1984 grams of water recovery Cheng Shui.Cold air type compressed-air drier is exactly that the condensed water cooling down is discharged by automatic drain valve so that the water content of compressed air substantially reduces by pressure-air cooling to about 3 DEG C.
A kind of present invention cold air circulating compressed air freeze dryer, as shown in Figure 1, including cold medium compressor 3, air cooled chiller 4, pre-cooling regenerator 5, vaporizer 6, condenser 7, automatic drain valve 9, reservoir 10, air inlet 1 is located at air cooled chiller 4 side, air cooled chiller 4 connects pre-cooling regenerator 5, pre-cooling regenerator 5 connects vaporizer 6, automatic drain valve 9 is installed on below vaporizer 6 air outlet, cold medium compressor 3, condenser 7, vaporizer 6, reservoir 10 is sequentially connected by pipeline, form refrigerant circulation passage, it is characterized in that: vaporizer 6 air outlet connects to the air inlet of condenser 7, the gas outlet of condenser 7 connects to pre-cooling regenerator 5, the cooling material of condenser 7 is the dried cold air that vaporizer 6 is discharged.
Compressed air flows into pre-cooling regenerator 5 after air inlet 1 enters air cooled chiller 4 radiating and carries out heat exchange so that the temperature entering the compressed air of vaporizer 6 reduces with the cold air that is dried of condenser 7 backflow；Compressed air after heat exchange flows into vaporizer 6, and the liquid freon in vaporizer 6, by compressed air heating evaporation, absorbs heat simultaneously, heat in compressed air is taken away by freon, itself cools down rapidly, and condensate moisture therein becomes water droplet, flows out through automatic drain valve 9.Air after cooling flows into condenser 7 through vaporizer 6 air outlet.
Pre-cooling regenerator 5 is to carry out precooling treatment using the cold air that is dried of condenser 7 backflow to compressed air, if not having pre-cooling regenerator 5, high temperature compressed air is directly entered vaporizer 6, makes refrigeration power consumption increase about one times.The energy has not only been saved in the setting of pre-cooling regenerator 5, also so that be dried air temperature gone up so that discharge duct outer wall to be not temperature too low and dew condensation phenomenon.
The outer wall of pre-cooling regenerator 5 and the internal copper pipe of vaporizer 6 is cased with aluminum fin-stock, can reduce the impact to copper pipe for the air, it is to avoid brass tube fracture while increasing heat exchange area.
Gaseous state freon after evaporation enters cold medium compressor 3 after vaporizer 6 pipe outlet separates drop and preheating through reservoir 10, and cold medium compressor 3 exports the gaseous state freon of High Temperature High Pressure.The gaseous state freon of High Temperature High Pressure, through condenser 7, is condensed into the liquid freon of normal temperature high voltage.
Described cold medium compressor 3 adopts high temperature full seal type reciprocating compressor, and compact conformation, small volume, lightweight, noise is low, Energy Efficiency Ratio is high.
Condenser 7 is cooled down to the gaseous state freon of high temperature using the dried cold air of vaporizer 6, changes tradition and relies on cooling fan or the type of cooling of cooling water, saves members, saved the energy simultaneously.
If the liquid freon of condenser 7 output exceeds certain pressure value, it is connected to supertension protection switch 15 deferred action on condenser 7 output channel, is protected.Device for drying and filtering 14 plays the effect of impurity in filter liquid state freon.Heating power expansion valve 13 is throttle mechanism, and the liquid freon of normal temperature high voltage flows through heating power expansion valve 13, and because of its throttling action, the liquid freon being converted to Room-temperature low-pressure flows in the pipeline of vaporizer 6, flows out vaporizer 6, enter reservoir 10 after heat absorption evaporation.The outlet of vaporizer 6 gaseous state freon, equipped with pressure gauge, monitors the pressure that vaporizer 6 exports gaseous state freon.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any change or replacement expected without creative work, all should be included within the scope of the present invention.Therefore, protection scope of the present invention should be defined by the protection domain that claims are limited.
