1, plasma ultraviolet photolysis oxidation, this technology is still effective in treating low-concentration organic waste gas and odor, and the price is low and the operating cost is low. This technology can generally be used for low-concentration organic waste gas.
2. Catalytic combustion. The technology of catalytic combustion equipment is mature, and the effect of treating medium-concentration organic waste gas and odor is very good. However, if the concentration is too high, the concentration cost and operation cost will increase a lot. Because the desorption frequency of activated carbon is too high, the utilization rate of activated carbon will decrease, and the effect will not be good if the catalyst is used too much. According to our previous experience, it will be much better to add two-stage water washing before catalytic combustion and add some oxidants and other chemicals to the water.
Of course, other technologies are also effective, such as direct combustion of zeolite runner and RTO. The effect may be better, but the cost is high.
RTO has high cost and high operation cost, and is only suitable for high concentration and low air volume. The higher the concentration, the lower the operating cost. The higher the concentration of organic waste gas, the less natural gas or oil is used.
Zeolite runner is really easy to use, and the operating cost is relatively low, and the effect is also very good, that is, the cost is high, and the domestic technology can not meet the foreign standards, so there will be some small problems that affect the operation after a long time of operation, and the cost of equipment directly imported from Japan will be much higher.
Therefore, it is suggested to choose equipment according to the needs of our own factory to purify our air.
