Description

Technical Field

[0001] This utility model relates to the field of adsorption material technology, specifically to a composite fabric for capturing and adsorbing pollutants. Background Technology

[0002] Industrial flue gas emissions refer to the process by which pollutant-containing flue gas generated during industrial production is released into the atmosphere through facilities such as chimneys. Its treatment is a crucial aspect of pollution prevention and control. Pollutants in flue gas include particulate matter, sulfur dioxide, and nitrogen oxides. Existing technologies for pollutant adsorption and purification include various methods and approaches such as desulfurization and denitrification, particulate matter treatment, and VOCs treatment, which can reduce pollutant concentrations and achieve good purification effects. However, in addition to common pollutants, there is another substance in flue gas that needs to be separated: carbon dioxide.

[0003] Carbon dioxide is a major component of greenhouse gases, and its increased emissions are a significant factor contributing to global warming. Adsorbing carbon dioxide from flue gas can effectively reduce greenhouse gas emissions, and the adsorbed carbon dioxide can be recycled, creating economic value. While various materials and methods exist for absorbing carbon dioxide from flue gas, the practical application of combining multiple materials of different forms and volumes presents operational limitations and subsequent maintenance difficulties, indicating room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problems of operational limitations and subsequent maintenance difficulties caused by the combined use of various materials with different forms and volumes that adsorb carbon dioxide, and to provide a pollutant capture and adsorption composite fabric.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a pollutant capture and adsorption composite fabric, comprising a base layer one, a base layer two, and a base layer three;

[0006] The base layer includes a spunlace nonwoven fabric; the spunlace nonwoven fabric is coated with a MEA solution.

[0007] The second base layer includes a modified adhesive layer; the modified adhesive layer is made of silicone, and amine groups are introduced on the surface of the silicone.

[0008] The base layer includes a base fabric and a woven fleece fabric;

[0009] The base layer 1, base layer 2, and base layer 3 are detachable.

[0010] Furthermore, the MEA solution is coated onto the spunlace nonwoven fabric by impregnation.

[0011] Furthermore, the base fabric is made of polyester fiber material.

[0012] Furthermore, the woven fleece is woven from radial and weft yarns, with dust-absorbing grooves formed between adjacent radial and weft yarns.

[0013] Furthermore, several magnetic strips corresponding to magnetic poles are provided between the opposite sides of the first and second base layers; several magnetic strips corresponding to magnetic poles are provided between the opposite sides of the second and third base layers.

[0014] Furthermore, the base layer three is connected to an external HEPA filter.

[0015] Furthermore, the base fabric and the woven fleece are heat-pressed together.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] By integrating the three-layer base fabric structure, the adsorption capacity of the composite fabric for carbon dioxide is improved. It has a high degree of integration during use and is easy to install in adsorption and purification devices such as adsorption towers.

[0018] All three layers of base fabric are removable. When damage occurs, or when adsorption becomes saturated or the adsorption effect decreases, they can be disassembled and replaced individually or treated in other ways, which facilitates maintenance and improves practicality.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, in conjunction with Appendix Figure 1 , 2 A pollutant capture and adsorption composite fabric includes a base layer 1, a base layer 2, and a base layer 3; the base layer 3 is connected to an external HEPA filter, so that it passes through the HEPA filter before adsorption. The HEPA filter is mainly used to capture particulate dust larger than 0.5μm and various suspended matter to avoid affecting the adsorption effect.

[0025] Combined with appendix Figure 1 ,2 3. The base layer 1 includes a spunlace nonwoven fabric 4; the spunlace nonwoven fabric 4 is coated with MEA solution, which is applied to the spunlace nonwoven fabric 4 by impregnation; the spunlace nonwoven fabric has good liquid absorption and air permeability, and its porous structure can evenly distribute the MEA solution, thereby improving the adsorption efficiency of carbon dioxide.

[0026] Combined with appendix Figure 1 , 2 3. The base layer 2 includes a modified adhesive layer 5; the modified adhesive layer 5 is made of silica gel, and amine groups are introduced on the surface of the silica gel; amine-modified silica gel can effectively adsorb carbon dioxide, and its adsorption capacity and separation coefficient are significantly higher than those of traditional adsorbents; during the modification preparation, the activated silica gel is mixed with a silanizing agent, heated and stirred under reflux in a suitable solvent, so that the amine groups are successfully grafted onto the surface of the silica gel; amine-modified silica gel has good chemical stability, and after appropriate regeneration treatment, its adsorption performance can be restored, improving its economic efficiency;

[0027] Combined with appendix Figure 1 , 2 3. The base layer 3 includes a base fabric 6 and a woven fleece fabric 7. The base fabric 6 is made of polyester fiber. The base fabric 6 and the woven fleece fabric 7 are joined by hot-pressing composite. Hot-pressing composite means that each layer is pressurized and heated through a roller heat sealing composite device to make the connection stable. The woven fleece fabric 7 is made of radial and weft yarns woven together, and dust-absorbing grooves are formed between adjacent radial and weft yarns. The fleece fabric surface itself has a large number of pile columns, which increases the surface area and has a good dust-absorbing effect. Combined with the dust-absorbing grooves, it can adsorb tiny impurities that HEPA has not fully adsorbed.

[0028] Combined with appendix Figure 1 , 2 The base layer 1, base layer 2, and base layer 3 are detachable. Specifically, each base layer 1 and base layer 2 has several magnetic strips 8 corresponding to magnetic poles on opposite sides; each base layer 2 and base layer 3 has several magnetic strips 9 corresponding to magnetic poles on opposite sides. The base layer 1, base layer 2, and base layer 3 can be quickly separated by magnetic strips 8 and 9. When damage occurs, or when the adsorption becomes saturated or the adsorption effect decreases, they can be disassembled and replaced individually or treated in other ways, which facilitates maintenance and improves practicality.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
