Above-mentioned existing execution documents and materials are " liquid sterilant is stifling by heating evaporation gas "." evaporation " is known physical reactions process.Current methods has weak point: 1. need the not non-equipment of price; It is bigger that 2. floor space is installed; 3. need heat powers such as vapours; 4. relate to the HTHP facility, the production safety risk is higher; 5. the facility relative fixed is difficult for machine many places and uses; 6. cost is higher, invests bigger; 7. use the operation time longer at every turn; 8. equipment cleans difficulty, or the like.

3. summary of the invention

For overcome existing known use to central air conditioner system with the deficiency of fluid-like state disinfectants such as Peracetic acid by the stifling cumbersome approaches of heating evaporation gas, the utility model device, tie up to central air-conditioning case air intake the sprayer unit that can control flow, filter impurity, clean compressed air is set, the disinfectant atomization gas is circulated in air-conditioning duct, clean area and installations and facilities thereof with air-conditioning wind, keep certain hour, can not only reach the stifling purposes of liquid sterilant gas such as Peracetic acid equally, and quicker and convenient.The technical scheme that its technical problem that solves the utility model bactericidal unit adopts is: with a Plastic Drum (19L drinks the pure water bottle and gets final product), Peracetic acid is waited until that the class disinfectant packs in the bottle, tight with the perforated rubber stopper lid, suction glass-tube (about ￠ 10mm), connect No. 4 glass sand filtration balls (filtering out impurities), connect gate valve switch (control flow), connect three-way pipe (approximately

Stainless steel tube), air inlet (return air) end at air-conditioning box is opened an aperture, the disinfectant conduit enters air-conditioning box, end is not loaded onto the micropore atomization shower nozzle, utilizes compressed air, high pressure control disinfectant flow, disinfectant is atomized in central air-conditioning case air intake district, see through with the wind: roughing efficiency air filter → medium effeciency filter → air supply duct → high efficiency particulate air filter → clean room zone → return air duct carries out circulatory fumigation again, keeps certain hour, sterilizes.

The know-why that the utility model central air conditioner system bactericidal unit adopts: class disinfectants such as Peracetic acid or formaldehyde are blended in the air by heating evaporation, it is physical process, utilizing the high temperature compressed air atomizing to be mixed in the air equally also is physical process, the dosage of disinfectant of the same race is identical, and the effect of sterilization is consistent.

Annotate: 1. clean workshop all is equipped with clean air compression system usually, and the on-the-spot air-pressure tube lashup being got final product (being equipped with the fast-assembling pipe joint) if do not possess the place of air compressor system, is equipped with a 0.7pma, 0.10m ³/ min, 1.5KWHP-2.0 type air compressor machine get final product (commercially available about 400 yuan/platform), have that clean rank requires with addition of air cleaner, general place then need not to filter out impurities in the thimerosal.

2. because of the central air-conditioning zone is not suffocating sterilization every day, but periodically sterilization regularly so package unit can fixedly mount, can be made combination quick assembling coupling a tractor serves several purposes.

The beneficial effect of the utility model central air conditioner system bactericidal unit is: 1. device is simple and easy to assembling, can produce this device in batches; 2. install and do not take up an area of; 3. need not auxiliary equipment such as vapours; 4. the production safety risk is extremely low; 5. facility need not fixed installation, but the assembly fast-assembling, and use machine many places; 6. easy and simple to handle, running is quick, shortens working hours; 7. equipment cleans easier; 8. cost is low, small investment, and operating cost is low, or the like.
