Why the use of activated carbon towers for waste gas treatment equipment is decreasing

In the early stages of environmental protection, activated carbon towers are used in exhaust gas treatment applications. It can be used in almost all industries, and it has been rationally used and transformed by many environmental companies in the later period. It was an effective and economical organic waste gas treatment device at the time, but why is the application currently decreasing? Discuss personal reasons for the following reasons.

The main reasons for the reduced use of activated carbon towers in exhaust gas treatment equipment are:

1. After the activated carbon is used for a period of time, it adsorbs a large amount of adsorbate, gradually saturates and loses its ability to work. If it is severe, it will penetrate the filter layer, so the activated carbon should be regenerated or replaced. Improper handling after activated carbon saturation can cause secondary pollution.

2. At present, low-temperature plasma exhaust gas treatment technology has emerged in the field of exhaust gas treatment. It is the use of generated high-energy electrons, free radicals and other active particles to activate, ionize, and crack the various components of industrial exhaust gas, causing decomposition, oxidation, and other columns. The complex chemical reactions are then subjected to multi-stage purification to eliminate odors and odor pollutants emitted by various pollution sources, so that toxic and harmful gases can be reduced in toxicity and non-toxic.

Compared with low-temperature plasma technology, the traditional corona discharge has a wide range of applications. Almost all odor odors produced in chemical production processes can be treated and have a good decomposition effect on dioxin. It has the advantages of good treatment effect, low operating cost, no secondary pollution, stable operation, easy operation and management, and instant use.

Now that the environmental protection requirements are continuously increasing, it is difficult to control the standards for activated carbon alone. This is one of the reasons why the activated carbon tower is continuously reduced in the exhaust gas treatment equipment.

It is not activated carbon tower is not used? It is wrong! Activated carbon adsorption tower is also widely used in furniture wood, chemical coatings, metal surface treatment such as spraying, painting, drying and other processing, or role and want to deal with the role.
