Organic waste gas treatment, also known as VOCs waste gas treatment. Due to the complexity of the organic waste gas composition, the size of the exhaust gas volume, and the level of the waste gas concentration, the organic waste gas treatment solutions and the waste gas treatment equipment used are also different. Xicheng environmental protection organic waste gas treatment solution, namely: one-key automatic turnkey waste gas treatment system, see Xicheng environmental protection VOCs treatment for details. The customer case of organic waste gas treatment and the selection of waste gas treatment equipment are only for customers' understanding and reference. The introduction is as follows:

Organic waste gas treatment

Exhaust gas introduction: Organic exhaust gas, also known as VOCs exhaust gas, is volatile organic compounds (volatile organic compounds). VOC in the ordinary sense refers to volatile organic compounds; however, the definition in the environmental sense refers to the active type of volatile organic compounds, that is, the type of volatile organic compounds that can cause harm.

Main components: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds.

Main sources: industrial semiconductors, microelectronics, electronics factories, painting factories, chemical plants, pharmaceutical factories and other industries.

Main hazards: hazards to humans: short-term inhalation can cause headaches, nausea, vomiting, fatigue and other symptoms. In severe cases, convulsions and coma can occur, and it can damage the liver, kidneys, brain and nervous system, and cause memory loss. as a result of. When the concentration is too high, it can also cause fatal and acute poisoning. Polycyclic aromatic hydrocarbons also have strong carcinogenicity.

Hazard to the environment: VOC is a key precursor for the formation of PM2.5 and ozone, which is physiologically toxic. VOC emitted by pollution sources and primary pollutants such as industrial exhaust gas, smoke, dust, natural dust, etc., undergo photochemical reactions to generate photochemical smog of secondary pollutants, which will form haze when floating in the air for a long time. In addition, the heat generated by the photochemical reaction combined with the heat emitted by industrial facilities, to a certain extent, destroys the condensation conditions of the cloud and fog turning into rain and snow, resulting in increased fog and reduced rain and snow. In addition, some secondary pollutants have water absorption, and some photochemical reactions will form fine water droplets, which also aggravates the formation of dense fog.

An Introduction

Wet scrubber adsorption system

Wet scrubber adsorption: This technology can efficiently absorb organic waste gas such as benzene, alcohol, ketone, ester, gasoline, etc., and is suitable for the treatment of waste gas with high air volume and low concentration. The method uses wet scrubber + activated carbon adsorption filtration, combined with the action of a fan to adsorb organic waste gas molecules, and has a good adsorption effect on the waste gas of organic solvents such as benzene, alcohols, ketones, esters, and gasoline.

Exhaust gas scrubber system

  • Applicable concentration: 0-300 mg/m3

  • Applicable air volume: 1000-100000 m3/h

  • Processing efficiency: 80-90%

Performance characteristics:

1. The adsorption efficiency is as high as 90%, the adsorption capacity is large, and the application range is wide;

2. Convenient maintenance without excessive manpower input requirements;

3. Large specific surface area, good selective adsorption, and capable of processing a variety of mixed waste gas at the same time;

4. PP wet scrubber + activated carbon has the characteristics of a wide range of sources and low prices;

5. Easy and safe operation.

6. The PP wet scrubber equipment has the characteristics of chemical corrosion resistance and flame retardant.
