Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, specifically a modular assembly waste gas treatment device. Background Technology

[0002] Some waste gas treatment devices use a single treatment method, which makes it difficult to achieve efficient purification for complex waste gas components; other devices have unreasonable structural designs, resulting in unstable connections between components, which easily leads to leakage, and require a lot of manpower and time for equipment maintenance.

[0003] In the field of waste gas treatment, modular design is gaining increasing attention. Modular design can improve the flexibility and scalability of the equipment, facilitating combination and adjustment according to different waste gas treatment needs. However, existing modular waste gas treatment devices still have some shortcomings. For example, some modules have poor compatibility and cannot achieve seamless integration; some devices, although claiming to have multiple treatment functions, do not show good synergy between modules in actual operation, affecting the overall treatment effect.

[0004] Furthermore, there is a certain lag in the intelligent control of waste gas treatment. Many devices cannot accurately monitor the quality of treated waste gas in real time, nor can they automatically adjust treatment parameters according to actual conditions, leading to unstable treatment efficiency and energy waste. Therefore, we propose a modular, assembled waste gas treatment device. Utility Model Content

[0020] Please see Figure 1-3 This utility model provides a technical solution: a modular assembled waste gas treatment device, including a pretreatment box 1, an air inlet pipe 11 on the side of the pretreatment box 1, a box cover 12 detachably connected to the top of the pretreatment box 1, multiple insertion slots 14 arranged horizontally in the inner cavity of the pretreatment box 1, a filter module 15, a particle filter module 16 and a photocatalytic module 17 arranged front and back in the insertion slots 14, the side of the pretreatment box 1 is connected to a purification box 2 through a connecting pipe 19, a water tank 21 is provided on the side of the purification box 2, a water pump 22 is provided on the water tank 21, the top of the water pump 22 is connected to an atomizing nozzle 24 installed in the purification box 2 through a lift pipe 23, an exhaust valve 28 is provided on the top of the purification box 2, and a waste gas detection sensor 29 is provided on the exhaust valve 28, a circulation pump 3 is provided on the side of the purification box 2, and the circulation pump 3 is connected to the pretreatment box 1 through a circulation pipe 31.

[0021] First, insert the filter module, particle filter module, and photocatalytic module sequentially into the insertion slots 14 inside the pretreatment box 1, ensuring that each module is installed in place and securely connected. Then, fix the box cover 12 to the top of the pretreatment box 1 with bolts through the connection holes 13, completing the assembly of the pretreatment box.

[0022] I. Connection of the overall device

[0023] Connect the connecting pipe 19 on the side of the pretreatment tank 1 to the purification tank 2, ensuring a good seal at the connection point to prevent exhaust gas leakage. Next, install the water tank 21 at a suitable position on the side of the purification tank 2, install the water pump 22 on the water tank 21, and connect one end of the riser pipe 23 to the top of the water pump 22 and the other end to the atomizing nozzle 24 installed inside the purification tank 2. The atomizing nozzle 24 is fixed on the bracket 25. Then, install the filter layer 26 in the lower part of the inner cavity of the purification tank 2, and connect the return pipe 27 to the purification tank 2 and the water tank 21. Finally, install the circulation pump 3 on the side of the purification tank 2 and connect it to the pretreatment tank 1 through the circulation pipe 31. Install the exhaust gas detection sensor 29 on the exhaust valve 28 and electrically connect it to the controller. Install the display screen 18 on the pretreatment tank 1 and electrically connect it to the exhaust gas detection sensor 29.

[0024] II. Waste Gas Treatment Process

[0025] Exhaust gas enters the pretreatment chamber 1 through the intake pipe 11. First, it passes through the filter module 15, which intercepts larger particulate impurities such as dust and fibers. Then, the exhaust gas enters the particulate filter module 16, which further removes smaller particles, such as PM2.5. Finally, the exhaust gas reaches the photocatalytic module 17, where, under the action of photocatalysis, the organic pollutants in the exhaust gas are decomposed into harmless substances such as carbon dioxide and water.

[0026] The pre-treated exhaust gas enters the purification chamber 2 through the connecting pipe 19. At this time, the water pump 22 starts, drawing water from the water tank 21 and delivering it to the atomizing nozzle 24 through the riser pipe 23. The atomizing nozzle atomizes the water and sprays it into the exhaust gas, allowing the remaining pollutants in the exhaust gas to be further absorbed by the water or removed through other chemical reactions. The purified exhaust gas rises to the exhaust valve 28, where the exhaust gas detection sensor 29 detects the exhaust gas and transmits the detection results to the display screen 18 for display.

[0027] If the exhaust gas detection sensor 29 detects that the exhaust gas still does not meet the emission standards, the controller controls the circulation pump 3 to start based on the detection result, drawing the exhaust gas from the pretreatment tank 1 back into the purification tank 2 for circulation treatment until the exhaust gas meets the emission standards. During the purification process, the water filter layer 26 filters the downstream water, and the filtered water flows back to the water tank 21 through the return pipe 27 for recycling.

[0028] In the above scheme, the pretreatment box 1 and the box cover 12 are respectively provided with connection holes 13 for bolt engagement. The connection holes 13 between the pretreatment box 1 and the box cover 12 are designed to fit tightly with the bolts, ensuring the sealing and stability of the box. This design not only facilitates the installation and disassembly of the box cover, but also effectively prevents exhaust gas leakage and ensures the treatment effect.

[0029] In the above scheme, a display screen 18 is installed on the pretreatment box 1, and the display screen 18 is electrically connected to the exhaust gas detection sensor 29. The display screen 18 is installed in a conspicuous position in the pretreatment box 1, and displays parameters such as exhaust gas concentration, temperature, and pressure monitored by the exhaust gas detection sensor 29 in real time. This design allows operators to intuitively understand the various indicators in the exhaust gas treatment process, making it easy to adjust the treatment parameters in a timely manner and ensure the exhaust gas treatment effect.

[0030] In the above scheme, the atomizing nozzle 24 is mounted on the bracket 25. The atomizing nozzle 24 is mounted inside the purification chamber 2 via the bracket 25 to ensure its stability during operation. The atomizing nozzle atomizes the water in the water tank 21 into fine water droplets, which come into full contact with the exhaust gas, further absorbing or reacting residual pollutants in the exhaust gas and improving purification efficiency.

[0031] In the above scheme, a water filter layer 26 is provided in the lower part of the inner cavity of the purification tank 2, and the purification tank 2 is connected to the water tank 21 through a return pipe 27. The water filter layer 26 is located in the lower part of the inner cavity of the purification tank 2 and is used to filter impurities generated during the purification process, preventing them from entering the water tank 21. The return pipe 27 returns the purified water from the purification tank 2 to the water tank 21, realizing the recycling of water resources, reducing waste, and meeting environmental protection requirements.

[0032] In the above scheme, the exhaust gas detection sensor 29 is electrically connected to the controller. The exhaust gas detection sensor 29 is installed on the exhaust valve 28 of the purification box 2 to monitor the quality of the treated exhaust gas in real time. The sensor 29 is electrically connected to the controller and transmits the monitoring data to the controller. The controller automatically adjusts the treatment process according to the preset emission standards, such as starting the circulation pump 3 for secondary treatment, to ensure that the exhaust gas meets the emission standards.

[0033] In the above scheme, the air intake pipe 11 is connected to the exhaust gas emission mechanism. Exhaust gas enters the pretreatment box from the air intake pipe 11.

[0034] Working principle:

[0035] This modular, assembled waste gas treatment device includes the following stages during use:

[0036] Pre-treatment stage: Exhaust gas enters the pre-treatment box 1 through the inlet pipe 11. First, it passes through the filter module 15, which intercepts larger particulate impurities such as dust and fibers. Then, the exhaust gas enters the particulate filter module 16, which further removes smaller particles such as PM2.5. Finally, the exhaust gas reaches the photocatalytic module 17, where, under the action of photocatalysis, the organic pollutants in the exhaust gas are decomposed into harmless substances such as carbon dioxide and water.

[0037] Purification Stage: After pretreatment, the exhaust gas enters the purification chamber 2 through the connecting pipe 19. At this time, the water pump 22 starts, drawing water from the water tank 21 and delivering it to the atomizing nozzle 24 through the lift pipe 23. The atomizing nozzle atomizes the water and sprays it into the exhaust gas, allowing the remaining pollutants in the exhaust gas to be further absorbed by the water or removed through other chemical reactions. The purified exhaust gas rises to the exhaust valve 28, where the exhaust gas detection sensor 29 detects the exhaust gas and transmits the detection results to the display screen 18 for display.

[0038] Recirculation treatment stage: If the exhaust gas detection sensor 29 detects that the exhaust gas still does not meet the emission standards, the controller controls the circulation pump 3 to start based on the detection results, drawing the exhaust gas from the pretreatment tank 1 back into the purification tank 2 for recirculation treatment until the exhaust gas meets the emission standards. During the purification process, the water filter layer 26 filters the downstream water, and the filtered water flows back to the water tank 21 through the return pipe 27 for recycling.
