Composite adsorbing material structure and manufacturing method thereof

Abstract

The invention discloses a composite adsorption material structure. The composite adsorption material structure comprises a ceramic skeleton, zeolite particles, carbon particles and holes, the ceramicskeleton is a loose structure; the zeolite particles, the carbon particles and the holes are distributed in the ceramic skeleton; the adjacent holes are communicated with each other, and the holes arecommunicated with the outside; part of the surfaces of the zeolite particles and part of the surfaces of the carbon particles are exposed in the holes, and the micro-pores in the surfaces of the zeolite particles exposed in the holes and the micro-pores in the surfaces of the carbon particles exposed in the holes can be communicated with the outside through the holes. After adsorption saturation,the material can be repeatedly used for a long time through desorption regeneration. The material is suitable for waste gas treatment, sewage treatment and soil remediation in the fields of industry,agriculture, service industry and the like. In the use process, the effect of primarily filtering waste gas and sewage is also achieved. The invention further discloses a manufacturing method of thecomposite adsorbing material structure.

Problems solved by technology

[0002] Under the situation of increasingly serious air, water and soil pollution, the harmless treatment of pollutants is urgent. At present, a variety of technical means have been applied to environmental treatment, including the adsorption technology of activated carbon and zeolite molecular sieve, especially activated carbon. Adsorption technology has been widely used in the fields of air purification and water purification. Although activated carbon has good adsorption performance, it also has obvious defects. The main problem is that activated carbon cannot withstand too high desorption temperature, otherwise it is prone to the risk of burning and fire. Low-temperature desorption is difficult to completely desorb some adsorbed substances. Over time, the activated carbon will gradually become clogged and the adsorption function will be gradually lost.

At present, the service life of most activated carbons does not exceed one year. Frequent replacement of activated carbons leads to high environmental protection costs. Moreover, a large amount of waste activated carbons will cause secondary pollution to the environment.

Adsorption materials such as zeolite runner and zeolite honeycomb made of zeolite have good adsorption performance and are suitable for high-temperature desorption, and their service life is greatly improved. However, due to the high price of zeolite products, it is difficult for enterprises with limited economic capacity to afford , leading to the failure of the current zeolite adsorption products to be widely used in the market

[0003] In addition, when filtering air with dust or sewage with particles, granular activated carbon or zeolite products are easily blocked, while honeycomb activated carbon and zeolite products cannot filter large particles, and additional pre-filters are required. Road filter treatment device, increased investment costs
