Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an adsorption and recovery device for uniform contact of waste gas. Background Technology

[0002] As enterprises place greater emphasis on environmental protection, they are demanding higher efficiency in waste gas treatment. Waste gas adsorption and recovery devices are environmental protection equipment used to treat volatile organic compounds (VOCs) or other valuable components in industrial waste gas, achieving waste gas purification and resource recovery through adsorption.

[0003] Traditional adsorption and recovery devices typically allow waste gas to pass directly through the adsorption section during use, which does not effectively guide the injected waste gas. When the waste gas flow rate is large, the airflow distribution within the device becomes uneven, resulting in localized penetration. This leads to low overall adsorption efficiency and insufficient utilization of the adsorbent. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adsorption and recovery device for uniform contact of waste gas, so as to solve the problem that when the waste gas flow rate is large, the airflow distribution in the device is uneven, local penetration occurs, which leads to a decrease in overall efficiency and the adsorbent cannot be fully utilized.

[0005] In view of this, the present invention provides an adsorption and recovery device for uniform contact of exhaust gas, including a housing, an air inlet pipe fixedly installed on one side of the housing, a first adsorption part and a second adsorption part provided inside the housing, and an air guide mechanism provided inside the housing. The air guiding mechanism includes a first air guiding component, a mounting cylinder, a fixing plate, and a third air guiding component. The fixing plate is fixedly installed on the inner wall of the housing. The first air guiding component is fixedly installed inside the fixing plate. A through hole is opened inside the fixing plate. A threaded rod is fixedly installed at one end of the mounting cylinder. The mounting cylinder is fixedly installed on one side of the first air guiding component through the threaded rod. The third air guiding component is fixedly installed on the inner wall of the mounting cylinder. Several flow-rectifying grids are fixedly installed on one side of the inner wall of the mounting cylinder. The mounting cylinder is connected to the inside of the housing through the flow-rectifying grids. A perforated plate is fixedly installed on the inner wall of the mounting cylinder.

[0006] Optionally, both the first air guide and the third air guide are conical, the third air guide has an arc surface on its side wall, and a plurality of air guide plates are fixedly installed on the side wall of the third air guide.

[0007] Optionally, the first adsorption part is fixedly installed on one side of the porous plate, and an exhaust hole is provided at one end of the mounting cylinder.

[0008] Optionally, a second air guide is fixedly installed on one side of the fixed plate. The second air guide is located on one side of the through hole, and the cross-section of the second air guide is semi-circular.

[0009] Optionally, a connector is fixedly installed on one side of the fixed plate, and the connector is located at the connection between the fixed plate and the first air guide.

[0010] Optionally, a mounting bracket is installed inside the housing, and the second adsorption part is fixedly installed inside the mounting bracket.

[0011] Optionally, the inner wall of the housing is provided with a mounting cavity, and a locking block is movably connected inside the mounting cavity by a spring. The side wall of the mounting bracket is provided with a locking groove that matches the locking block.

[0012] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages: 1. The adsorption and recovery device for uniform contact of waste gas of this utility model adopts an air guiding mechanism. The first air guiding component can guide the waste gas entering through the air inlet pipe, so that the waste gas is led to the fixed plate and flows into the housing through the through hole in the fixed plate. The waste gas is guided through the through hole so that the waste gas is evenly sprayed on the second adsorption part in the housing. At the same time, the small space between the housing and the mounting cylinder can avoid uneven airflow distribution and avoid local penetration. By setting the mounting cylinder, when the waste gas flow rate is large, the excess waste gas enters the mounting cylinder through the rectifier grid. The third air guiding component and the perforated plate guide the waste gas entering the mounting cylinder so that the waste gas is evenly sprayed on the first adsorption part, thereby ensuring adsorption efficiency.

[0013] 2. The adsorption and recovery device for uniform contact of waste gas of this utility model can support the card block by setting a spring, and can fix the mounting frame by setting a card slot when the card block is inserted into the card slot, so that the mounting frame can be fixed in the housing, and at the same time, it is convenient to remove and install the mounting frame.

[0017] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0018] The adsorption and recovery device for uniform contact of waste gas according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings. Example

[0019] For easier understanding, please refer to Figures 1 to 4 An embodiment of the adsorption and recovery device for uniform contact of exhaust gas provided by this utility model includes a housing 1, an air inlet pipe 2 fixedly installed on one side of the housing 1, a first adsorption part 8 and a second adsorption part 11 provided inside the housing 1, and an air guide mechanism provided inside the housing 1. The air guiding mechanism includes a first air guiding component 4, a mounting cylinder 5, a fixing plate 12, and a third air guiding component 17. The fixing plate 12 is fixedly installed on the inner wall of the housing 1. The first air guiding component 4 is fixedly installed inside the fixing plate 12. A through hole 13 is opened inside the fixing plate 12. A threaded rod 6 is fixedly installed at one end of the mounting cylinder 5. The mounting cylinder 5 is fixedly installed on one side of the first air guiding component 4 through the threaded rod 6. The third air guiding component 17 is fixedly installed on the inner wall of the mounting cylinder 5. Several flow-rectifying grilles 16 are fixedly installed on one side of the inner wall of the mounting cylinder 5. The mounting cylinder 5 is connected to the inside of the housing 1 through the flow-rectifying grilles 16. A perforated plate 9 is fixedly installed on the inner wall of the mounting cylinder 5.

[0020] It should be noted that by setting the first air guide 4, the exhaust gas entering through the air inlet pipe 2 can be guided to the fixed plate 12, and then flow into the housing 1 through the through hole 13 in the fixed plate 12. The exhaust gas is guided through the through hole 13, so that the exhaust gas is evenly sprayed onto the second adsorption part 11 in the housing 1. At the same time, the small space between the housing 1 and the mounting cylinder 5 can avoid uneven airflow distribution and local penetration. When the exhaust gas flow rate is large, the excess exhaust gas enters the mounting cylinder 5 through the rectifier grille 16. The third air guide 17 and the perforated plate 9 guide the exhaust gas entering the mounting cylinder 5, so that the exhaust gas is evenly sprayed onto the first adsorption part 8, thereby ensuring adsorption efficiency.

[0021] In some embodiments, such as Figure 2 As shown, both the first air guide 4 and the third air guide 17 are conical. The side wall of the third air guide 17 has an arc surface. Several air guide plates 18 are fixedly installed on the side wall of the third air guide 17. The second air guide 14 is fixedly installed on one side of the fixed plate 12. The second air guide 14 is located on one side of the through hole 13. The second air guide 14 has a semi-circular cross section. The connector 15 is fixedly installed on one side of the fixed plate 12. The connector 15 is located at the connection between the fixed plate 12 and the first air guide 4.

[0022] It should be noted that the second air guide 14 can be used to guide the exhaust gas through the through hole 13, and the connecting piece 15 can make the airflow more uniform when the exhaust gas passes through the fixed plate 12.

[0023] In some embodiments, such as Figure 3 As shown, the first adsorption part 8 is fixedly installed on one side of the porous plate 9, the mounting cylinder 5 has an exhaust hole 7 at one end, the housing 1 has a mounting frame 10 installed inside, and the second adsorption part 11 is fixedly installed inside the mounting frame 10.

[0024] It should be noted that the adsorption section is composed of zeolite and carbon fiber materials. The gap between the mounting cylinder 5 and the inside of the shell 1 forms an exhaust port. The mounting frame 10 is located in the exhaust port, so that the exhaust gas can be adsorbed and treated when passing through the first adsorption section 8 or the second adsorption section 11. Example

[0025] In some embodiments, such as Figure 4 As shown, the inner wall of the housing 1 has an installation cavity 19, and a locking block 20 is movably connected inside the installation cavity 19 by a spring. The side wall of the mounting bracket 10 has a locking groove 21 that matches the locking block 20.

[0026] It should be noted that the spring can be used to support the locking block 20, and the locking slot 21 can be set so that the locking block 20 can be locked and fixed to the mounting bracket 10 when it is locked into the locking slot 21, thereby locking and fixing the mounting bracket 10 inside the housing 1, and making it convenient to take out and install the mounting bracket 10.

[0027] Working principle: During use, exhaust gas enters through the inlet pipe 2. The first air guide 4 can guide the exhaust gas entering through the inlet pipe 2, so that the exhaust gas is led to the fixed plate 12 and flows into the housing 1 through the through hole 13 in the fixed plate 12. The exhaust gas is guided through the through hole 13, so that the exhaust gas is evenly sprayed on the second adsorption part 11 in the housing 1. At the same time, the small space between the housing 1 and the mounting cylinder 5 can avoid uneven airflow distribution and avoid local penetration. By setting the mounting cylinder 5, when the exhaust gas flow is large, the excess exhaust gas enters the mounting cylinder 5 through the rectifier grille 16. The third air guide 17 and the perforated plate 9 guide the exhaust gas entering the mounting cylinder 5, so that the exhaust gas is evenly sprayed on the first adsorption part 8.

[0028] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
