A variety of industrial organic waste gas treatment solutions

The pollution of the environment is becoming more and more serious. There are numerous solutions for the treatment of industrial organic waste gas. The specific and feasible solutions are as follows:

(1) Biological methods: Microorganisms degraded for certain odorous substances are attached to the filler. The number of microorganisms in the tank is large, and they can tolerate larger pollution loads than the biological filter. The inert filter material can be replaced without changing the operating conditions.

The biological method must strictly control the pH, temperature, and humidity conditions to suit the growth of microorganisms; it is necessary to continuously add nutrients, making its application limited.

(2) Adsorption method: It is applicable to the treatment of low-concentration, high-purification odorous gases; it has high purification efficiency and can handle multi-component malodorous gases.

Considering regular replacement of adsorbent, the cost of adsorbent is expensive; the odor gas to be treated requires lower temperature and dust content; it may cause secondary pollution.

(3) Catalytic combustion method: It is suitable for the treatment of flammable gases with high concentration and small gas volume; the purification efficiency is high, and odorous substances are completely oxidized and decomposed.

The equipment is easily corroded, consumes fuel, has high processing costs, and is prone to secondary pollution.

(4) Low-temperature plasma: Efficient treatment, effective removal of volatile organic compounds (VOC), inorganic substances, hydrogen sulfide, ammonia, mercaptans and Other major pollutants and a variety of bad odor; reaction conditions for the normal temperature and pressure; no Add any substance, only need to set the corresponding exhaust pipe and exhaust power; 2 hours of continuous work, stable and reliable operation; will not produce secondary pollution.

Before treatment, the exhaust gas needs to be pretreated to remove the dust and moisture in the exhaust gas.

(5) Electron beam irradiation technology: It effectively removes sulfur dioxide and nitrogen oxides, and has high desulfurization efficiency and is less prone to secondary pollution.

There is only a very narrow range of gas flow rates.
