Description

Odor gas production system for performance testing of atmospheric environment prevention facilities {ODOR GAS MANUFACTURING SYSTEM FOR PERFORMANCE TEST OF AIR ENVIRONMENT PREVENTION FACILITY}

The present invention relates to an odor gas production system for performance testing of air quality prevention facilities, and more specifically, to a performance test of air quality prevention facilities configured to continuously supply odor gases for performance testing of air quality prevention facilities. This is about the odorous gas production system.

High-concentration and non-degradable odorous gases emitted from processes such as public sewage treatment plants, petrochemical plants, and oil refineries are discharged from air environment prevention facilities such as RTO (Regenerative Thermal Oxidizer), RCO (Regenerative Catalytic Oxidizer), VCU (Vapor Combustion Unit), and It is discharged to the outside in a purified state by a chemical scrubber, which is a cleaning and absorption facility.

These air quality prevention facilities must be operated to satisfy the emission conditions of, for example, the Bad Odor Prevention Act and the Clean Air Conservation Act. It is desirable to evaluate whether such air quality prevention facilities are properly treating odorous gases through performance tests before they are installed at sites such as factories.

However, even if you want to test the performance of the air quality prevention facility as described above, it is not possible to verify the performance of the air quality prevention facility because odor sample gas for the performance test cannot be prepared. In other words, the performance test itself for air quality prevention facilities is not being carried out.

Therefore, there is a need for various research and development on odor gas production systems for performance testing of air quality prevention facilities that continuously supply odor gas to air quality prevention facilities.

This air supply unit 200 may include an air tank 210, an air compression unit 220, an air dryer 230, an air supply line 240, a nitrogen membrane 250, and an air supply valve 260. .

Here, the air tank 210 stores air supplied to the mixer 300. At this time, the air stored in the air tank 210 may be air existing in the atmosphere.

And the air compression unit 220 compresses the air flowing in from the outside to a predetermined pressure and supplies it to the air tank 210. Accordingly, the air contained in the air tank 210 may be compressed air.

And the air supply line 240 is configured to connect the air tank 210 and the mixer 300. Compressed air received in the air tank 210 can be supplied to the mixer 300 through the air supply line 240.

And the air dryer 230 is provided on the air supply line 240. This air dryer 230 is provided between the air tank 210 and the nitrogen membrane 250, and as air is supplied from the air tank 210 to the nitrogen membrane 250, moist air is supplied to the air dryer 230.
