Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment, and specifically to a composite adsorption module. Background Art
[0002] In the field of waste gas treatment, traditional adsorption materials such as activated carbon and zeolite molecular sieves have certain limitations in treating organic waste gases. For example, although activated carbon has a high adsorption capacity, its service life is short and it needs to be replaced frequently; although zeolite molecular sieves perform well under certain conditions, their pore size distribution is narrow, limiting the adsorption range for organic matter, and their adsorption performance is affected in high humidity environments.
[0003] In addition, although existing inorganic honeycomb adsorption materials have improved adsorption performance, their structure is relatively simple and difficult to adapt to the waste gas treatment needs under different working conditions. Different filtration equipment has different plate sizes for the primary treatment position of waste gas, and it is necessary to customize plates of the appropriate size according to the specific equipment, which is costly.
[0004] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design a composite adsorption module with a simple structure. Utility Model Content
[0005] This invention provides a composite adsorption module to address the problems of existing technologies.
[0006] The purpose of this utility model can be achieved through the following technical solution: A composite adsorption module includes: a substrate body, the substrate body including an activated carbon adsorption layer one, an infinitely circular honeycomb adsorption layer and an activated carbon adsorption layer two connected in sequence, the substrate body is provided with dovetail inserts symmetrically on the top and bottom, and the substrate body is provided with dovetail slots symmetrically on the left and right to match the dovetail inserts.
[0007] In a further improvement, the infinitely variable honeycomb adsorption layer is made by activating natural zeolite and sepiolite as raw materials.
[0008] A further improvement is that the insertion angle of the dovetail slot is 45 degrees.
[0009] In a further improvement, the thickness of the activated carbon adsorption layer is 2cm to 4cm.
[0010] In a further improvement, the thickness of the activated carbon adsorption layer is 2cm to 4cm.
[0011] In a further improvement, the thickness of the infinitely variable honeycomb adsorption layer is 8cm to 10cm.
[0012] Compared with existing technologies, the advantages of this novel composite adsorption module are as follows:
[0013] The front-end activated carbon adsorption layer performs primary adsorption, reducing the adsorption pressure on the infinitely variable honeycomb adsorption layer. This layer has a high adsorption capacity, enabling rapid adsorption of organic matter in the waste gas. A secondary adsorption treatment is then performed by the infinitely variable honeycomb adsorption layer, made from activated natural zeolite and sepiolite. This layer has a wider pore size distribution, allowing for efficient adsorption of various organic compounds. The rear-end activated carbon adsorption layer further treats the waste gas after adsorption by the infinitely variable honeycomb adsorption layer, reducing waste gas backflow. The dovetail insert and slot design simplify module installation and improves efficiency. Modules can be assembled to a size slightly larger than the primary treatment plate size of the filtration equipment, and then the plate is clamped in place using a fixing structure. This allows for size selection based on actual needs, reducing costs. Attached Figure Description

[0019] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.
[0020] Example 1
[0021] A composite adsorption module includes: a substrate body 1, wherein the substrate body 1 includes an activated carbon adsorption layer 11, an infinitely variable honeycomb adsorption layer 12 and an activated carbon adsorption layer 13 connected in sequence, and dovetail inserts 14 are symmetrically arranged on the upper and lower sides of the substrate body 1, and dovetail slots 15 matching the dovetail inserts 14 are symmetrically arranged on the left and right sides of the substrate body 1.
[0022] As a further preferred embodiment, the infinitely variable honeycomb adsorption layer 12 is made by activating natural zeolite and sepiolite as raw materials.
[0023] As a further preferred embodiment, the dovetail slot 15 has an insertion angle of 45 degrees, which helps to improve the structural stability of the module.
[0024] As a further preferred embodiment, the thickness of the activated carbon adsorption layer 11 is 2cm to 4cm; the thickness of the activated carbon adsorption layer 13 is 2cm to 4cm; and the thickness of the electrodeless honeycomb adsorption layer 12 is 8cm to 10cm. The thickness of the activated carbon adsorption layer 1 and the activated carbon adsorption layer 2 is between 2cm and 4cm, and the thickness of the electrodeless honeycomb adsorption layer is between 8cm and 10cm. This design ensures adsorption efficiency and facilitates module replacement and maintenance.
[0025] like Figures 1-2 As shown, the working principle of this utility model is as follows:
[0026] This novel composite adsorption module combines an activated carbon adsorption layer with a discrete honeycomb adsorption layer, fully utilizing the advantages of both. It contains no organic components and features high safety and high adsorption capacity. The initial adsorption is achieved through the front-end activated carbon adsorption layer 11, reducing the adsorption pressure on the discrete honeycomb adsorption layer 12. The activated carbon adsorption layer 11 has a high adsorption capacity, enabling rapid adsorption of organic matter in the waste gas. A secondary adsorption treatment is then performed through the discrete honeycomb adsorption layer 12, made from activated natural zeolite and sepiolite. The discrete honeycomb adsorption layer 12 has a wider pore size distribution, enabling efficient adsorption of various organic compounds. The rear-end activated carbon adsorption layer 11 performs a tertiary adsorption treatment on the waste gas adsorbed by the discrete honeycomb adsorption layer 12, and also reduces waste gas backflow.
[0027] Compared to traditional honeycomb activated carbon, zeolite rotors, and zeolite molecular sieves, this product boasts significant advantages. It achieves a benzene adsorption (static) of 330 mg / g, a benzene adsorption (dynamic) of 120 mg / g, a TVOc adsorption of 255 mg / g, and a purification efficiency of 95%. Desorption is complete within 15 minutes at 250°C, and its desorption performance shows no decline even after long-term continuous use, meeting the requirements for long-term online monitoring. Its service life is 5-8 years, during which there are no replacement, installation, or hazardous waste disposal costs. The overall operating cost is approximately 20% of that of activated carbon, greatly reducing the burden on emissions compliance. The infinitely variable honeycomb adsorption layer has a wide pore size distribution, ranging from 0-380 Å, with an average pore size of 64 Å. Compared to zeolite rotors, it achieves full coverage of known organic molecules under actual working conditions, overcoming the limitations of zeolite molecular sieves. It eliminates the need for prior selection, enabling broad-spectrum application. With a water absorption rate of <5%, it exhibits strong hydrophobicity, maintaining high-efficiency adsorption of organic matter even in high-humidity southern regions and under pre-spray conditions.
[0028] Furthermore, the design of the dovetail insert and dovetail slot makes the module installation simpler and the splicing more efficient. The module size can be spliced to a plate size slightly larger than the primary treatment position of the filtration equipment's exhaust gas, and then the plate is fixed and clamped by a fixing structure. Thus, the size can be selected according to the actual situation, reducing costs.
[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
