Description

Technical Field

[0001] The utility model relates to the field of waste gas denitration treatment equipment, and more specifically, to a waste gas denitration treatment device. Background Art

[0002] With the improvement of people's living standards and the continuous development of industry, the industrial production industry has spread throughout people's lives. In some industrial production processes, certain industrial waste gases will be generated. Industrial waste gas refers to the general term of various pollutant-containing gases discharged into the air during fuel combustion and production processes in enterprise factory areas, which is harmful to the respiratory tract and health of the human body. During the treatment of industrial waste gas, a waste gas denitration treatment device will be used. The waste gas passes through a filter screen, and the filter screen will block and filter large-particle dust. However, with long-term use, the mesh holes on the filter screen are easily blocked by large-particle dust, and the large-particle dust blocked and filtered by the filter screen is not convenient for centralized collection and treatment, affecting the efficiency of industrial waste gas treatment.

[0003] For example, Chinese Utility Model Patent No. 202221441739.2 proposed a waste gas denitration treatment device. First, by starting the drive motor, the output rotating shaft is driven to rotate, and the output rotating shaft drives the dialing roller to rotate. When the outer wall of the side of the dialing roller away from the center contacts the bottom of the filter screen plate, the filter screen plate is pushed upward, causing the spring telescopic rod to be stretched. When the outer wall of the side of the dialing roller away from the center disengages from the bottom of the filter screen plate, the spring telescopic rod is released from stretching, driving the filter screen plate to reset and generating vibration, so that the large-particle dust blocked in the mesh holes of the filter screen plate shakes out from the mesh holes. The shaken-out particles enter the collection box along the inclined surface of the filter plate for collection. However, this patent cannot ensure that the shaken-out particles move upward to the surface of the filter screen plate. When the filter screen plate vibrates, the particles will also move downward, resulting in affecting subsequent waste gas treatment. Moreover, the filter screen plate is fixedly connected to the spring telescopic rod, making it very difficult to replace the filter screen plate. When the waste gas reacts with the treatment liquid, the waste gas cannot be fully contacted with the treatment liquid, resulting in incomplete desulfurization and denitration chemical reactions in the waste gas, and the waste gas will still pollute the environment after being discharged.

[0004] Therefore, the utility model proposes a waste gas denitration treatment device. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the technical problems proposed in the above background art, and provide a waste gas denitration treatment device. When in use, the waste gas and the treatment liquid can be fully contacted through the delivery pipe and the connecting pipe, and the filter plate can be prevented from being blocked by large-particle dust by installing a filter screen at the air inlet.

[0006] To achieve the above object, the present utility model provides the following technical solutions: It includes a cabinet body. A groove is opened at the top end of the cabinet body. A filter plate is embedded in the groove. A limiting hole is opened at the front end of the filter plate. An air inlet hole is opened on the left side of the cabinet body. A storage cavity is opened in the upper middle of the cabinet body. A connecting pipe is connected to the right side wall of the storage cavity. A conveying pipe is connected to the bottom end of the storage cavity. A processing cavity is provided at the bottom end of the storage cavity. An exhaust valve is connected to the left side wall of the processing cavity. A sewage discharge valve is connected to the right side wall of the processing cavity. A connecting block is connected to the front end of the cabinet body. A limiting column is connected to the middle of the rear side wall of the connecting block. Springs are connected to the left and right ends of the rear side wall of the connecting block.

[0007] Further preferred solution: The air inlet hole is located on the left side of the filter plate, and a filter net is fixedly installed at the end of the air inlet hole located inside the cabinet body.

[0008] Further preferred solution: The filter plate is located inside the storage cavity, and a sealing block is fixedly installed at the connection between the filter plate and the groove.

[0009] Further preferred solution: The springs are fixedly connected to the connecting block and the side wall of the cabinet body respectively, and the limiting column is located in the limiting hole.

[0010] Further preferred solution: The conveying pipe is in a spiral shape, and the bottom end of the conveying pipe penetrates through the bottom end of the storage cavity and is located in the processing cavity.

[0011] Further preferred solution: The top end of the connecting pipe penetrates through the right side wall of the storage cavity, and the bottom end penetrates through the bottom end of the storage cavity and is connected to the conveying pipe.

[0012] Further preferred solution: The exhaust valve is located at the top end of the left side wall of the processing cavity, and the sewage discharge valve is located at the bottom end of the right side wall of the processing cavity.

[0013] Beneficial effects:

[0014] 1. By setting the conveying pipe and the connecting pipe, the contact time between the waste gas and the treatment liquid can be increased, so that the waste gas can be in full contact with the treatment liquid;

[0015] 2. By setting the limiting hole and the limiting column, the filter plate can be fixed in the groove. By setting the spring and the connecting block, the filter plate can be quickly replaced inside the cabinet body;

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-4 in the embodiments of the present utility model.

[0023] Please refer to Figures 1-4 In the embodiments of the present utility model, an exhaust gas denitrification treatment device includes a cabinet body 1. A groove 5 is opened at the top end of the cabinet body 1. A filter plate 2 is embedded and installed in the groove 5. A limiting hole 14 is opened at the front end of the filter plate 2. An air inlet hole 3 is opened on the left side of the cabinet body 1. A storage cavity 6 is opened in the upper middle of the cabinet body 1. A connecting pipe 4 is connected to the right side wall of the storage cavity 6. A delivery pipe 8 is connected to the bottom end of the storage cavity 6. A treatment cavity 7 is provided at the bottom end of the storage cavity 6. An exhaust valve 9 is connected to the left side wall of the treatment cavity 7. A drain valve 10 is connected to the right side wall of the treatment cavity 7. A connecting block 13 is connected to the front end of the cabinet body 1. A limiting post 12 is connected to the middle of the rear side wall of the connecting block 13. Springs 11 are connected to the left and right ends of the rear side wall of the connecting block 13. First, the exhaust gas enters the cabinet body 1 from the air inlet hole. The exhaust gas passes through the filter plate 2 to isolate the dust particles in the exhaust gas, and then enters the treatment cavity 7 through the delivery pipe 8. At the same time, the treatment liquid is poured into the connecting pipe 4, and the treatment liquid also flows into the delivery pipe 8 through the connecting pipe 4, so that the treatment liquid and the exhaust gas have a primary reaction in the delivery pipe 8. Then the treatment liquid enters the treatment cavity 7 through the delivery pipe 8. At this time, the treatment liquid and the exhaust gas react again, so that the desulfurization and denitrification in the exhaust gas can undergo a complete chemical reaction. After the exhaust gas treatment is completed, the exhaust valve 9 is opened, and the treated exhaust gas is discharged through the exhaust valve 9. Then the drain valve 10 is opened, and the liquid in the treatment cavity 7 is discharged through the drain valve 10.

[0024] In the embodiment of the present utility model, the air inlet hole 3 is located on the left side of the filter plate 2, and a filter net is fixedly installed at one end of the air inlet hole 3 inside the cabinet body 1. By providing the filter net, it is possible to prevent the surface of the filter plate 2 from being blocked by large-particle dust, thereby affecting the subsequent use of the filter plate 2.

[0025] During use, the waste gas enters the cabinet body 1 through the air inlet hole. Since a filter net is installed on the surface of the air inlet hole, the waste gas will be initially filtered, isolating the large-particle dust in the waste gas outside the cabinet body 1, thereby preventing the filter plate 2 from being blocked by large-particle dust and affecting the subsequent filtration of the waste gas by the filter plate 2.

[0026] The filter plate 2 is located in the storage cavity 6, and a sealing block is fixedly installed at the connection between the filter plate 2 and the groove 5. The spring 11 is fixedly connected to the connecting block 13 and the side wall of the cabinet body 1 respectively. The limiting column 12 is located in the limiting hole 14. By providing the limiting hole 14 and the limiting column 12, the filter plate 2 can be fixed in the groove 5. By providing the spring 11 and the connecting block 13, the filter plate 2 can be quickly replaced inside the cabinet body 1.

[0027] During use, first pull the connecting block 13 to move the limiting column 12 forward, then directly insert the filter plate 2 into the groove 5, and finally release the connecting block 13. At this time, the connecting block 13 moves backward under the pulling force of the spring 11, thereby driving the limiting column 12 to move backward, so that the limiting column 12 moves into the limiting hole 14 in the filter plate 2, thus realizing the fixation of the filter plate 2. When the filter plate 2 needs to be disassembled, pull the connecting block 13 to move the limiting column 12 forward to leave the limiting hole 14, and then directly pull the filter plate 2 out of the groove 5.

[0028] The top end of the connecting pipe 4 penetrates through the right side wall of the storage cavity 6, and the bottom end penetrates through the bottom end of the storage cavity 6 and is connected to the conveying pipe 8. The conveying pipe 8 is spiral-shaped, and the bottom end of the conveying pipe 8 penetrates through the bottom end of the storage cavity 6 and is located in the treatment cavity 7. The exhaust valve 9 is located at the top end of the left side wall of the treatment cavity 7, and the sewage discharge valve 10 is located at the bottom end of the right side wall of the treatment cavity 7. By providing the conveying pipe 8 and the connecting pipe 4, the contact time between the waste gas and the treatment liquid can be increased.

[0029] During use, the waste gas flows to the right end of the storage cavity 6 after being filtered by the isolation plate, and then is conveyed into the treatment cavity 7 by the conveying pipe 8. At the same time, the treatment liquid is poured into the connecting pipe 4, and the treatment liquid also flows into the conveying pipe 8 through the connecting pipe 4, thereby causing a primary reaction between the treatment liquid and the waste gas in the conveying pipe 8. Since the conveying pipe 8 is spiral-shaped, the flow time of the waste gas and the treatment liquid in the conveying pipe 8 can be increased, and thus the waste gas can be fully contacted by the treatment liquid.
