Abstract

PURPOSE:To prevent the breeding of microorganisms and prevent the mixing of microorganisms by sterilizing the microorganisms adhering to a filter and a piping system by installing an ozone generating part and an ozone decomposing part on the suction side of a compressor. CONSTITUTION:When microorganisms in a piping are sterilized, an ozone generating part 11 is operated by the start of a compressor 2, and the ozonized air is blown out from an air gun 6 through a filter 1, the compressor 2, a air storage tank 3, a piping 4 and a valve 5, and sterilizes the microorganisms adhering to the piping system. When air is cleaned, an ozone decomposing part 12 operates with the operation of the zone generator 11, and the microorganisms in the air are sterilized by the ozonized air which is sucked in, the then almost all the residual ozone is decompressed, by the ozone decomposing part 12, and only the cleaned air is blown out from the air gun 6 through the filter 1, the compressor 2, the air storage tank 3, the piping 4, and the valve 5.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for purifying cleaning air when cleaning containers and instruments using compressed air.

"Prior Art" Figure 2 shows a system diagram of a compressor used in air guns, etc., where 1 is a dust removal filter, 2 is a compressor, 3 is an air storage tank, 4 is air piping, 5 is a stop valve, 6 is a compressor system diagram used in air guns, etc. indicates an air gun, and 7 indicates an object to be cleaned with air.

``Problems to be Solved by the Invention'' Compressors are generally installed in locations with poor environmental conditions, so a small amount of microorganisms are present in the air blown into them. Therefore, compressor air filter 1
At the same time, microorganisms adhere to and multiply, and the microorganisms that pass through the filter enter the piping system and adhere to and multiply on the air storage tank 3, air piping 4, valve 5, air gun 6, etc., causing trouble in the piping system. Become.

In addition, microorganisms attached to the piping system peel off, fly out from the air gun, and adhere to the equipment or equipment being cleaned or cleaned, which is one of the causes of contact failure and rust.

``Means for Solving the Problems'' The present invention mixes highly concentrated ozone gas into the suction air when the compressor is started or at regular intervals to sterilize microorganisms attached to the filter and piping system. In addition to preventing breeding, when cleaning equipment and equipment, the blown air is sterilized with ozone and then decomposed air is used so that no residue remains, eliminating the contamination of microorganisms.

``Effect'' Ozone has a strong oxidizing effect, so the ozonized air sucked in from the compressor destroys the cell walls of microorganisms attached to the inside of filters and pipes, causing them to die.

In addition, the air used for cleaning equipment, etc., sterilizes microorganisms mixed in the air with ozone, and residual ozone is completely removed and becomes clean air, so there is no corrosion of pipes, etc. Become.

"Example" FIG. 1 shows an example of the compressor air purification method of the present invention.

1 is a suction filter, 2 is a compressor, 3 is an air storage tank, 4 is an air pipe, 5 is a stop valve, 6 is an air gun, and 7 is an object to be cleaned with the compressed air.

Further, 11 indicates an ozone generation section, and 12 indicates an ozone decomposition section.

In FIG. 1, operation can be switched between ozone sterilization mode and air sterilization mode depending on the timing of operating the ozone decomposition section.

Ozone sterilization mode is a mode used for the purpose of sterilizing microorganisms in the piping when there is a concern that microorganisms may grow in the piping system, such as when the compressor is started.

That is, by starting the compressor 2, the ozone generating section 1
1 is activated, ozonized air is blown out from the air gun 6 via the filter 1, the compressor 2, the gas storage tank 3, the piping 4, and the valve 5, thereby sterilizing microorganisms attached to this piping system.

Moreover, the air sterilization mode is a mode used when performing air cleaning.

That is, with the operation of the ozone generating section 11, the ozone decomposing section 1
2 operates, and after the microorganisms in the air are sterilized by the ozonized air sucked in, the ozone decomposition unit 12 decomposes the residual ozone to almost zero, leaving only clean air.
It is blown out from an air can 6 via a filter 1, a compressor 2, an air storage tank 3, a pipe 4, and a valve 5.

"Effects of the Invention" The method according to the present invention, that is, when cleaning instruments and containers with an air gun, the air mode shown in FIG. 1 is used,
If you switch to the sterilization mode shown in Figure 1 when the compressor is started or at regular intervals to sterilize the piping system, the air gun will always be able to blow out clean air. There is no microbial damage to the cleaned or washed equipment and equipment, and it is highly effective in preventing contact failure and rust.
