Activated carbon It is very common in our life. It can absorb impurities to treat sewage, Activated carbon manufacturer Explain the function of activated carbon in waste gas treatment.

1. Large specific surface area and high effective adsorption capacity. Since the surface area of the activated carbon for waste gas treatment with the same weight is nearly ten times that of the activated carbon particles for coal waste gas treatment, the weight of the activated carbon for waste gas treatment to be filled is very small, but the adsorption efficiency is very high. According to the organic gas content of the waste gas treatment and other physical characteristics, the adsorption efficiency is between 85% and 98%, and the multi-stage adsorption process can reach 99.99%, It is far higher than the maximum adsorption rate of 88% of the ordinary activated carbon particle adsorption method, and the volume and total weight are very small.

2. Short travel and fast speed of adsorption and desorption; Low energy consumption for desorption and regeneration. The adsorption capacity of waste gas treatment activated carbon for organic gas is several to dozens of times greater than that of ordinary granular waste gas treatment activated carbon (GAC), and it also has good adsorption capacity for inorganic gas, and can maintain a high adsorption and desorption speed and a long service life. If heated with steam for 10-30 minutes, it can be completely desorbed, with good heat resistance. It can withstand high temperature of more than 1000 ℃ in inert gas and ignition point of more than 450 ℃ in air.

3. Variable shape, easy to use. There are columnar spherical particles, so it is very convenient to replace and will not cause any harm to human body. The activated carbon manufacturer prompts that special activated carbon for waste gas treatment with special performance can be produced according to needs; It has good strength and will not cause secondary pollution.

4. Direct combustion method: use auxiliary fuels such as gas or oil to burn, heat the mixed gas, and decompose harmful substances into harmless substances under high temperature; This method is simple in process and small in investment. It is suitable for waste gas with high concentration and small air volume, but has high requirements for safety technology and operation.  

5. Catalytic combustion method: the waste gas is heated and converted into harmless and odorless carbon dioxide and water through catalytic combustion; This method has the advantages of low ignition temperature, energy saving, high purification rate, convenient operation, small floor area, large investment and is suitable for high temperature or high concentration organic waste gas.

6. Adsorption method: (1) direct adsorption method: organic waste gas is treated by waste gas activated carbon adsorption The purification rate can reach more than 95%, the equipment is simple and the investment is small, but the activated carbon for waste gas treatment is frequently replaced, and the working procedures of loading and unloading, transportation, replacement, etc. are increased, leading to an increase in operating costs. (2) Adsorption recovery method: use fiber waste gas to treat activated carbon to adsorb organic waste gas, and use superheated steam to blow back when it is nearly saturated for desorption and regeneration; This law requires the provision of necessary steam.

7. New adsorption catalytic combustion method: this method combines the advantages of adsorption method and catalytic combustion method, uses new adsorption materials (honeycomb waste gas treatment activated carbon) for adsorption, introduces hot air for desorption and analysis after approaching the drinking water, and then introduces the desorbed waste gas into the catalytic combustion bed for flameless combustion to thoroughly purify it. The hot gas is recycled in the system, greatly reducing energy consumption. This method has the characteristics of stable and reliable operation, low investment, low operation cost and convenient maintenance. It is suitable for the treatment of waste gas with large air volume and low concentration. It is a mature and practical method for the treatment of organic waste gas in China at present.
