Description

Technical Field

[0001] This utility model specifically relates to the field of waste gas filtration technology, and more specifically to a rapid industrial waste gas filtration and emission device. Background Technology

[0002] Industrial waste gas contains harmful substances such as particulate matter, heavy metals, and toxic gases. Direct emission of these harmful substances into the air will cause air pollution. Inhaling this polluted air can cause respiratory diseases, poisoning, and other health problems. Therefore, industrial waste gas needs to be filtered before it can be emitted. The core of industrial waste gas filtration and emission is graded purification and compliant emission. By using a filtration system adapted to the composition of the waste gas, dust and harmful gases can be efficiently removed, thereby reducing the harm to the environment and human body after emission.

[0003] However, traditional exhaust gas filtration devices are mostly one-piece structures with fixed internal filter components and reagents. They cannot adjust the filtration level or reagent type according to the composition and concentration of exhaust gas, resulting in limited treatment effect on complex exhaust gases. Moreover, maintenance of the internal filter requires disassembling multiple connecting structures, and cleaning, repairing or replacing components is time-consuming, labor-intensive, and has a long maintenance cycle. Utility Model Content

[0004] The purpose of this invention is to provide a rapid industrial waste gas filtration and emission device. The modularly designed filter housing can be installed in varying numbers to suit different waste gas treatment processes, improving filtration efficiency. Furthermore, the detachable filter element assembly inside the modular filter housing facilitates quick disassembly, thereby improving cleaning and maintenance efficiency. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An industrial waste gas rapid filtration and emission device includes a waste gas spray treatment tower, a wastewater collection and storage chamber installed at the bottom of the waste gas spray treatment tower, and a modular filter box shell arranged in a rectangular array connected to the bottom of the waste gas spray treatment tower via connecting pipes.

[0006] As a further technical solution of this utility model, the spliced ​​filter box shell includes a hollow box body. The top two sides of the hollow box body are provided with air inlet and outlet holes. An annular positioning protrusion is integrally provided around the air inlet and outlet hole on one side, while a positioning boss is integrally provided around the air inlet and outlet hole on the other side.

[0007] As a further technical solution of this utility model, the positioning boss is provided with a sealing groove corresponding to the annular positioning protrusion, and the annular positioning protrusion and the sealing groove can be inserted and matched, and a sealing ring is also embedded in the inner side of the sealing groove.

[0008] As a further technical solution of this utility model, a detachable filter element assembly is also installed on the inner side of the hollow box.

[0009] As a further technical solution of this utility model, the detachable filter element assembly includes a sealing cover plate fixedly connected to the top of the hollow housing, and a mounting bracket inserted into the inside of the hollow housing is fixedly connected below the sealing cover plate.

[0010] As a further technical solution of this utility model, the inner side of the mounting bracket is fixedly connected with a filter plate in a rectangular array, and the inner side of the filter plate is also fixedly connected with an air guide bend.

[0011] As a further technical solution of this utility model, both sides of the hollow box are symmetrically fixedly connected with grooved hanging ears, and each of the grooved hanging ears is provided with a U-shaped groove, and the opening of the U-shaped groove faces away from the hollow box.

[0012] As a further technical solution of this utility model, one end of the air guide bend extends through the filter plate to the bottom of the inner side of the hollow box, and the other end is attached to the side of the hollow box. At the same time, the inner side of the air guide bend is connected to the inner side of the annular positioning protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention first determines the number of filtration cycles based on the chemical composition of the exhaust gas. Then, several hollow boxes are placed side by side, with different types of chemical agents placed in each box. The exhaust gas enters the chemical agents through a guide pipe. After the chemical components in the exhaust gas react with the chemical agents, they flow upwards and pass through multiple filter plates for multi-layer filtration, thereby improving the filtration effect of the exhaust gas. When installing multiple hollow boxes, it is necessary to distinguish the directions of the two sides of the hollow box to ensure that the annular positioning protrusion on the side of one hollow box is fully inserted into the sealing groove on the side of another hollow box. Through the interlocking cooperation between the sealing groove and the annular positioning protrusion, it is easy to quickly install multiple hollow boxes together, so that they can be used for different types of exhaust gas filtration and increase the scope of application. This invention allows for the removal of fasteners at the connection between the hollow housing and the sealing cover. The sealing cover is then moved upwards, and the mounting bracket at the bottom of the sealing cover allows the filter plate and air guide bend to separate from the inside of the hollow housing. This facilitates quick and easy cleaning and maintenance of the inside of the hollow housing and the filter plate, shortening maintenance time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 This utility model provides an industrial waste gas rapid filtration and emission device, including a waste gas spray treatment tower 2, a wastewater collection and storage chamber 1 installed at the bottom of the waste gas spray treatment tower 2, and a spliced ​​filter box shell 4 arranged in a rectangular array connected to the bottom of the waste gas spray treatment tower 2 through a connecting pipe 3. The spliced ​​filter box shell 4 includes a hollow box body 41. Both sides of the top of the hollow box body 41 are provided with air inlet and outlet holes. An annular positioning protrusion 45 is integrally provided around the air inlet and outlet hole on one side, while a positioning boss 43 is integrally provided around the air inlet and outlet hole on the other side.

[0024] The wastewater collection and storage tank 1 and the exhaust gas spray treatment tower 2 are both fixedly connected to the side of maintenance ladders 6, and the top of the maintenance ladders 6 is fixedly connected to a wind direction bag 7. Workers can climb up to the top of the wastewater collection and storage tank 1 and the exhaust gas spray treatment tower 2 through the maintenance ladders 6 to carry out maintenance.

[0025] Furthermore, the positioning boss 43 is provided with a sealing groove 44 corresponding to the annular positioning protrusion 45, and the annular positioning protrusion 45 and the sealing groove 44 can be inserted and engaged, and a sealing ring is also embedded in the inner side of the sealing groove 44.

[0026] By adopting the above technical solution, when installing multiple hollow boxes 41, it is necessary to distinguish the directions of the two sides of the hollow box 41 to ensure that the annular positioning protrusion 45 on the side of one hollow box 41 is fully inserted into the sealing groove 44 on the side of another hollow box 41. Through the interlocking cooperation between the sealing groove 44 and the annular positioning protrusion 45, it is easy to quickly install multiple hollow boxes 41 together, so that they can be used for different types of exhaust gas filtration and increase the scope of application.

[0027] More specifically, both sides of the hollow box 41 are symmetrically fixedly connected with grooved hanging ears 42, and each grooved hanging ear 42 has a U-shaped groove, with the opening of the U-shaped groove facing away from the hollow box 41.

[0028] Furthermore, a detachable filter element assembly 5 is also installed on the inner side of the hollow housing 41.

[0029] Furthermore, the detachable filter assembly 5 includes a sealing cover plate 51 fixedly connected to the top of the hollow housing 41, and a mounting bracket 52 inserted into the inside of the hollow housing 41 is fixedly connected to the bottom of the sealing cover plate 51.

[0030] By adopting the above technical solution, the fasteners at the connection between the hollow housing 41 and the sealing cover 51 are removed, and then the sealing cover 51 is moved upward. The mounting bracket 52 at the bottom of the sealing cover 51 can drive the filter plate 53 and the air guide bend 54 to separate from the inside of the hollow housing 41, thereby facilitating the quick and easy cleaning and maintenance of the inside of the hollow housing 41 and the filter plate 53, and shortening the maintenance time.

[0031] More specifically, the inner side of the mounting bracket 52 is fixedly connected to the filter plate 53 in a rectangular array, and the inner side of the filter plate 53 is also fixedly connected to the air guide bend 54. One end of the air guide bend 54 extends through the filter plate 53 to the bottom of the inner side of the hollow box 41, and the other end is attached to the side of the hollow box 41. At the same time, the inner side of the air guide bend 54 is connected to the inner side of the annular positioning protrusion 45.

[0032] By adopting the above technical solution, the number of filtration times is first determined according to the chemical composition of the exhaust gas. Then, several hollow boxes 41 are placed side by side, and different types of chemical agents are placed in each hollow box 41. The exhaust gas enters the chemical agents through the air guide bend 54. After the chemical components in the exhaust gas react with the chemical agents, they flow upward and pass through multiple filter plates 53 for multi-layer filtration, thereby improving the filtration effect of the exhaust gas.

[0033] A rubber sealing ring is fixedly connected to one end of the air guide bend 54 that is in contact with the hollow box 41. The rubber sealing ring connects the inner side of the annular positioning protrusion 45 with the inner side of the air guide bend 54. After the exhaust gas passes through the inner side of the annular positioning protrusion 45, it is directly guided into the bottom of the inner side of the hollow box 41 through the air guide bend 54 and then flows upward from the bottom.

[0034] The working principle of this utility model is as follows: First, determine the number of filtration cycles based on the chemical composition of the exhaust gas. Then, place several hollow housings 41 side-by-side. When installing multiple hollow housings 41, it is necessary to distinguish the directions of the two sides of each housing 41, ensuring that the annular positioning protrusion 45 on the side of one hollow housing 41 is fully inserted into the sealing groove 44 on the side of another hollow housing 41. Through the interlocking fit between the sealing groove 44 and the annular positioning protrusion 45, multiple hollow housings 41 can be quickly installed together. Then, place fasteners into two adjacent recessed lugs 42. Through the mutual cooperation of the fasteners and the recessed lugs 42, the hollow housings 41 are installed, and the exhaust gas flows from the annular positioning protrusion at the end... The exhaust gas enters the inner side of the air guide bend 54 through the protrusion 45. After being guided by the air guide bend 54, the exhaust gas directly enters the bottom of the inner side of the hollow box 41, allowing it to directly enter the bottom of the chemical agent. While reacting with the chemical agent, the exhaust gas moves upward. The exhaust gas passes through multiple layers of filter plates 53 and then through multiple hollow boxes 41 for filtration. It then enters the inner side of the exhaust gas spray treatment tower 2 through the connecting pipe 3. The exhaust gas spray treatment tower 2 uses a water pump to introduce water from the inside of the wastewater collection and storage bin 1 into the inner side of the exhaust gas spray treatment tower 2 for spraying, performing final treatment on the exhaust gas. Finally, it is discharged through the opening at the top of the exhaust gas spray treatment tower 2. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
