The shells adopt Bai Xianzi and Sha Xian shells, the two shells are separated, and the projected area of the shells is between 0.6 and 16 square centimeters. Of course, other double shell type shell pieces can be used as the shell.

The zeolite particles 3 are artificial zeolite particles;
the adhesive 2 is a sodium silicate fireproof inorganic adhesive;

Principle of operation
Because the finished product contains a large amount of zeolite (also called molecular sieve), the invention has good adsorption performance and permeability, can enable gas or liquid to pass through and contact the surfaces of zeolite particles in a low resistance state, can adsorb VOCs components flowing through air and harmful substances such as ammonia nitrogen components, heavy metals and the like in sewage, effectively absorb the VOCs components in the air and reduce the BOD value of the sewage, effectively filter and purify the fluid, can bear high temperature of 300 ℃ or more at most to keep structural integrity because the structure in the finished product is inorganic mineral, is suitable for high-temperature desorption after adsorption saturation, has more thorough desorption effect on adsorbates with high boiling point and pyrolysis gasification temperature, has higher flame retardant safety, has high rigidity as a framework and is not easy to break, can be repeatedly used for a long time, and can replace the existing adsorption materials such as active carbon. The skeleton formed by the shell sheets is selected, the effect is that the shells have irregular curved surface appearance, have lower stacking density, form larger gaps between the shells inside after stacking, have good permeability, are especially used for air purification, have the characteristic of low wind resistance, and can be energy-saving by using a fan with low wind pressure. The main component of the shell is calcium carbonate, has stable chemical property, has considerable rigidity and temperature resistance, is suitable for being used as a skeleton of an adsorption material, and is common waste with low cost.
The zeolite particles for purifying sewage have a particle size of 50-200 μm, and the zeolite particles used for the adsorption material for purifying air have a particle size of less than 50 μm.
Example 2: an efficient low-wind-resistance adsorption material comprises a shell 1, a binder 2 and zeolite particles 3; the zeolite particles 3 are bonded through the adhesive 2 and cover all the surfaces inside and outside the shell 1, and a compact zeolite particle 3 thin layer is formed on the inner and outer surfaces of the shell 1; one surface of the zeolite particles 3 is adhered to the surface of the shell 1 through the adhesive 2, the zeolite particles 3 on the other surface are exposed, and the zeolite particles 3 exposed outside are not covered by the adhesive 2.
The shell adopts abalone shell, and two shell pieces are separated.
The shell 1 is subjected to high-temperature treatment to remove organic matters on the surface, or the organic matters on the surface of the shell 1 are removed through chemical treatment.
The zeolite particles are combined with inorganic frameworks 4 by zeolite powder to form porous three-dimensional structure combined zeolite particles (shown in figure 2).
The zeolite powder is artificial zeolite powder;
the adhesive 2 is a sodium silicate fireproof inorganic adhesive;
the adhesive 2 is not dissolved by water after curing.
The particle size of the combined zeolite particles is 0.5-2mm;
the projected area of the adopted shells is between 0.6 and 16 square centimeters. Of course, other area sizes may be used as desired by the design.
Example 2 zeolite particles were combined with zeolite powder and inorganic framework 4 to form a porous three-dimensional structure (see fig. 2), which can hold more zeolite particles with a larger adsorption capacity than example 1, while the material supporting the fixed zeolite particles is a porous framework, which can ensure that most zeolite particles can contact gas or liquid flowing through, and the porous framework supporting the fixed zeolite particles can filter dust or suspended matters in the fluid, thereby reducing the problem of clogging of micropores of the zeolite particles. The embodiment can be applied to sewage filtration and purification and adsorption of VOCs gas in air.

step three: placing enough zeolite particles into another sealing roller, adding the shell with the adhesive thin layer into the sealing roller, and allowing the zeolite particles to adhere to the surface of the shell through the adhesive by rotating the roller.
If a portion of the zeolite particles has glue on the outer surface, there will be one or more layers of zeolite particles adhered to the other zeolite particles, until finally no more zeolite particles can be adhered, and the outermost layer of zeolite particles is partially uncovered by glue.
Step four: then the shell fully stuck with zeolite particles after the step three is sent into a drying tunnel, and the curing of the adhesive is accelerated by baking at about 200 ℃ so that the zeolite particles are firmly adhered to the surface of the shell;
step five: and then feeding the shell baked and solidified in the fourth step into another roller with meshes, flowing out the unnecessary zeolite particles which are not adhered with the shell from the meshes of the roller by rotating the roller, and finally obtaining a finished product of the adsorbing material, wherein the unnecessary zeolite particles flowing out of the meshes of the roller can be reused.
