With China's accession to the WTO, activated carbon produced in China has been purchased and used in large quantities by countries around the world for its superior performance and price. However, regardless of the shape of granular activated carbon, cylindrical activated carbon, or spherical activated carbon produced by using coal as a raw material or fruit shell or wood as a raw material, the dust attached to its surface cannot be completely removed, especially the basic On the premise of maintaining the original adsorption characteristics of activated carbon, remove dust adhered to the surface of activated carbon.

For a long time, the activated carbon dust-free technology that the market has been calling for has not been successfully developed. People have tried to wash the surface of activated carbon with water washing and wind blowing. Although there are certain effects, due to the friction between the activated carbon particles and the friction of the air flow on the surface of the activated carbon, new fine powders are formed. Therefore, the above method cannot fundamentally solve the problem. People have also tried to cover the activated carbon with high-molecular substances, but they have been disturbed by the original physical adsorption capacity and specific chemisorption capacity of the activated carbon.

Therefore, the industry's investment and attention to this technology is increasing day by day. However, unfortunately, the issue of energy consumption has not yet attracted enough attention from the industry. According to data, the energy consumption of the same product in China is 11 times that of Japan, and activated carbon may be one of them. The reason is that, on the one hand, people feel that it is running at a small profit, and on the other hand, they do not know where to start to improve economic efficiency.

It is at least incomplete to simply emphasize that low-price sales. Since the objective existence of competition is a well-known fact, the market cannot be transferred artificially, so it can only start with reducing energy consumption. Reducing energy consumption can reduce costs and increase benefits for enterprises, and energy saving is a long-term plan for national development for the benefit of the country and the people.
