Description

Portable Air Disinfection Device for Air Booth

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas reprocessing apparatus for a simple air booth, and more particularly, to an air booth installed in a public office, a hospital, a laboratory, a livestock farm, etc., and a large amount of infectious microorganisms and dust by pneumatic cleaning of the air booth. The present invention relates to a gas reprocessing apparatus for an air bus booth, which quickly and stably removes contaminants such as infectious microorganisms and dust mixed into a gas by reprocessing a gas into which contaminants such as contaminants are mixed.

Generally, various disinfection or cleaning devices are installed in public offices, hospitals, laboratories, livestock farms, etc. to clean, sterilize, and disinfect various microorganisms such as harmful bacteria remaining on visitors' skins and clothes, and contaminants such as dust and odor particles. have. In particular, as foot-and-mouth disease, a livestock epidemic, has spread throughout the country, the necessity of such cleaning devices is increasing.

Representative disinfection or cleaning device is spray spraying type that sterilizes disinfectant disinfectant directly to visitor, sterilizes contaminants adhered to visitor's clothes or skin through disinfectant disinfectant, and discharges gas at high pressure in closed booth. There is a pneumatic cleaning type that cleans contaminants through gas.

Here, the latter pneumatic cleaning type does not directly spray the disinfectant disinfectant to the visitor, unlike the former, there is no residual feeling or foreign substance caused by the disinfectant disinfectant solution, and contaminants remaining in the visitor's skin or clothing in a short time. It has the advantage that can be removed, and the structure is simple and is manufactured in a simple form, such as mobile, and also has the advantage that can be easily and quickly installed in public offices, hospitals, laboratories, livestock farms and the like.

However, the gas emitted by removing contaminants remaining on the skin or clothes of visitors is mixed with various microorganisms such as harmful bacteria and pollutants such as dust and odor particles, so they are released into the atmosphere without removing contaminants. If people or livestock are located nearby, they will be exposed to a large amount of pollutants, and if they are re-introduced into the air booth, the visitors will be directly exposed to a large amount of pollutants. Therefore, it is difficult to expect a stable cleaning or quarantine effect. High-pressure air discharged for the cleaning of visitors may act as a medium for secondary pollution of various infectious diseases.

In order to solve this problem, the related art is equipped with a gas reprocessing apparatus that sprays water finely into an air booth and gas that has been air-cleaned, and removes contaminants mixed in gas through a water treatment that finely sprays water into the gas. However, through such water treatment, there is a limit that can not stably remove a large amount of contaminants contained in the gas, and the water treatment type gas treatment device requires continuous water supply and is difficult to move due to its large volume. However, it is not suitable for simple air booths.

Therefore, there is a need in the art for the development and dissemination of an improved type of gas reprocessing device for an air booth that can quickly and stably remove a large amount of contaminants mixed in the gas discharged from a portable air booth that is easy to move. There is a situation.

As shown in the drawing, the discharge electrodes 32b-a fix the terminal portion to the perforations 32a-c of the discharge tube 32a through the insulator 32d with an insulating structure, and each discharge electrode 32b-a is a power supply device ( A high voltage current applied in 31b) is applied through a terminal portion exposed to the outside of the discharge tube 32a to generate a gliding arc.

And, behind the discharge tube 32a, a gas guide piece 32e for interfering with the transfer of the gas transferred to the outside of the arc generator 32b to guide and transfer the arc to the arc generator 32b in which the gliding arc is generated. Is placed.

Therefore, the gas transported to the outside of the arc generator 32b is guided into the arc generator 32b by the gas guide piece 32e and flows in, thereby stably removing contaminants while passing through the arc generator 32b. Is accomplished.

The discharge electrodes 32b-a are formed between the discharge electrodes 32b-a in a form in which a gap gradually widens from the rear of the inlets 32a-a to the front of the exhaust ports 32a-b. When a high-voltage current is discharged between a) to generate an arc, the arc is repeatedly glided from the rear to the front by a gas forced from the rear to the front through the inlets 32a-a, thereby gliding the arc area of a large area. To form.

At this time, the shortest gap distance between the discharge electrodes 32b-a is 0.2 mm or more and the longest gap distance is set in the range of 0.5 to 2.0 mm, and the thickness of the discharge electrode is set in the range of 0.5 to 4.0 mm. The gap distance and the thickness of is changed according to the high voltage condition such as the applied voltage, current and frequency, the ceramic to suppress the generation of arc, the insulation connection fitting made of high temperature polymer composite.

In addition, in the present embodiment, in implementing such an arc generator 32, the induction member 32c installed to be accommodated in the hollow of the discharge tube 32a and surrounding the outer side of the arc generator 32b is added to induce this induction. The member 32c allows the contaminants to be stably removed while the gas stays and circulates in the arc generator 32b.

Here, the induction member (32c) is composed of a reticular body formed with a plurality of main exhaust holes (32c-a) on the side wall, the inlet (32c-b) in communication with the inlet (32a-a) of the discharge tube (32a) in the rear Is formed and the inlet exhaust hole 32c-c is formed in the front to discharge a portion of the gas introduced through the inlet 32c-b to facilitate the gliding of the arc generated between the discharge electrodes 32b-a. do.

According to the present embodiment, when the main exhaust holes 32c-a of the induction member 32c are manufactured in a spiral shape or formed by obliquely drilling the main exhaust holes backward, the gas discharged through the main exhaust holes rapidly forms a vortex. As it is discharged, a rapid discharge of the gas from which the pollutant is decomposed through the arc generating unit can be achieved.

Therefore, some of the gas introduced into the arc generating unit 32b through the inlet 32c-b of the induction member 32c is discharged to the induction exhaust hole 32c-c formed in front, and the discharge electrode 32b-a. Glide the arc generated between the front to generate a gliding arc, the rest is circulated through the arc generating unit 32b and then discharged to the side through the main exhaust hole (32c-a) formed in the side wall, and then discharge tube (32a) Is discharged forward along the exhaust ports 32a-b.

Thus, in the arc generator 32 according to the present embodiment, all the gas introduced from the rear through the inlet 32c-b by the induction member 32c is not discharged to the front, and gas is supplied to the arc generator 32b.

In addition, the post-treatment catalyst filter layer 42 includes an ozone decomposition catalyst filter 42a and a residual pollutant decomposition catalyst filter 42b formed separately.

In this embodiment, the post-treatment catalyst filter layer 42 is decomposed to the ozone decomposition catalyst filter 42a and residual pollutants in the cartridge body 42c, similarly to the plasma generating unit 31 and the photocatalyst filter layer 33 of the main processing unit. The catalyst filter 42b is fixed to form a post-treatment filter cartridge 42 ', and the post-treatment filter cartridge 42' is installed in the cartridge charging portion 11c formed in the tunnel-shaped enclosure 10 to post-treatment catalyst By forming the filter layer 42, convenience is provided according to future maintenance.

In addition, as the carrier of each of the catalyst filters 42a and 42b, cordierite ceramics, porous fibers, and metal materials are used, and as the catalyst of the ozone decomposition catalyst filter, mainly 5 to 50% of manganese dioxide, copper, cobalt oxide, Alternatively, metal oxides based on manganese dioxide / copper oxide may be employed, and as catalysts of the residual pollutant decomposition catalyst filter, graphite, zeolite or silica-alumina catalysts, high metals (Pt, Au, Ag), and low cost metals (Ti Oxide catalysts containing Sn, W) can be employed.
