Description

Technical Field

[0001] This application belongs to the field of environmental protection equipment technology, and in particular relates to a waste gas treatment and recovery device based on air pollution prevention and control. Background Technology

[0002] In recent years, with economic development, a large number of chemical, coating, furniture, toy, electronics, and spraying enterprises have emerged. Coupled with insufficient investment in environmental protection, this has led to the emission of a large amount of industrial waste gas, resulting in a decline in air quality and serious harm to human health. The amount of waste gas emitted varies depending on the size of the factory and equipment.

[0003] A Chinese patent with publication number CN112808733B discloses an industrial waste gas treatment and purification device, including a base, a filter box, and a purification barrel. The base is a hollow structure, and the filter box is located on the upper left side of the base. A maintenance cover is threadedly connected to the upper end of the filter box, and an ultraviolet lamp is located in the middle of the lower end of the maintenance cover. A cleaning shaft is rotatably connected to the bottom of the filter box. The lower end of the cleaning shaft passes through the filter box and the base and is connected to a first driven wheel. A cleaning crossbar is located at the upper end of the cleaning shaft, and a brush is located at the upper end of the cleaning crossbar. A filter screen is located on the lower side of the filter box.

[0004] Although the above-mentioned waste gas treatment device has a good purification effect, the purification tank lacks a filter structure. After the purification tank has been working for a long time, the flocculated impurities inside will still have a certain impact on the filter cover connected to the water pump. This needs to be improved. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a waste gas treatment and recovery device based on air pollution prevention and control, which can recover impurities and harmful gases in waste gas and ensure the operational stability of the recovery device.

[0006] This application provides a waste gas treatment and recovery device based on air pollution control, comprising:

[0007] The purification tank is equipped with an air inlet and an air outlet.

[0008] A filter canister is placed on one side of the purification canister and connected to it; an ultraviolet lamp is installed inside the filter canister.

[0009] An air intake pipe, connected to an air intake port, is spiral-shaped;

[0010] The filtration system is installed on the purification tank.

[0011] The mixing mechanism is installed inside the purification tank;

[0012] The filtration mechanism includes a filter housing, a filter screen, a first connecting pipe, and a second connecting pipe. The filter screen is placed inside the filter housing. The first connecting pipe and the second connecting pipe are both connected between the purification tank and the filter housing. The first connecting pipe is connected to the top of the filter housing, and the second connecting pipe is connected to the bottom of the filter housing. The connection position between the first connecting pipe and the purification tank is higher than the connection position between the second connecting pipe and the purification tank.

[0013] The purification tank introduces exhaust gas through the air inlet, which is connected to the air inlet pipe, allowing the exhaust gas to be transported along the air inlet pipe to the filter tank. The filter tank filters dust and other impurities, and then ultraviolet lamps achieve rapid sterilization. It also has a strong ability to oxidize and decompose organic molecules, including malodorous substances. The gas is then transported back to the purification tank, where it flocculates. The flocculated material in the purification tank is filtered by the filtration mechanism, and the stirring mechanism improves the flocculation efficiency. The filtration mechanism is connected to the filter housing through the first and second connecting pipes. Water flow is generated in the filtration mechanism, allowing the water in the purification tank to pass through the filtration mechanism for filtration. The flocculated material is filtered through the filter screen, and the filter housing is installed on the outer wall of the purification tank with fasteners.

[0014] Furthermore, the filtering mechanism is provided with a first filter cover, which corresponds to the first connecting pipe.

[0015] The first filter cover is installed on the inner wall of the purification tank, with its opening facing the opposite direction to the rotation of the stirring mechanism. When the flocculent material enters the first filter cover, it is intercepted. The intercepted flocculent material and a small amount of water enter the filtration mechanism, keeping the water volume in the purification tank constant, ensuring the stability of the purification performance in the purification tank, and avoiding large-scale replacement of the water in the purification tank, thus improving water conservation.

[0016] Furthermore, a drain outlet is provided at one end of the filter housing.

[0017] The drain outlet facilitates the discharge of highly concentrated flocculent material from the filter housing, ensuring the filtration stability of the filtration mechanism and the ease of discharging the flocculent material.

[0018] Furthermore, both the second connecting pipe and the first connecting pipe are equipped with a heat exchange mechanism, the heat exchange mechanism comprising:

[0019] The heat exchange shells are respectively installed on the first connecting pipe and the second connecting pipe;

[0020] Spiral blades are installed inside the heat exchange housing;

[0021] The water inlet pipe is connected to the heat exchange shell corresponding to the second connecting pipe;

[0022] The water outlet pipe is connected to the heat exchange shell corresponding to the first connecting pipe;

[0023] The two heat exchange shells are connected to each other.

[0024] The exhaust gas introduced into the inlet pipe has a high temperature. The heat exchange mechanism is used to improve the energy utilization rate. When the water in the purification tank flows through the first connecting pipe and the second connecting pipe, heat exchange occurs through the heat exchange mechanism. The heat exchanged is used for other equipment or for power generation. The heat exchange medium flows in from the inlet pipe and flows out from the outlet pipe. The heat exchange shell and spiral blades increase the heat exchange efficiency between the heat exchange medium and the first connecting pipe and the second connecting pipe, respectively.

[0025] Furthermore, the purification tank includes:

[0026] A water pump is connected to the bottom of the purification tank;

[0027] Spray pipes are installed on the purification tank and connected to the water pump;

[0028] The second filter cover is installed at the connection between the water pump and the purification tank;

[0029] The connection between the second connecting pipe and the purification bucket corresponds to the second filter cover.

[0030] Water is drawn from the purification tank by a water pump and then sprayed out from the spray pipe. The decomposed organic molecules in the exhaust gas entering the purification tank are dissolved in the water. The second filter cover ensures that the water pump draws clean water. The second filter cover corresponds to the second connecting pipe, so that the water flushed out of the second connecting pipe acts on the second filter cover, reducing the adhesion of flocculent substances on the filter cover.

[0031] Furthermore, the filter canister includes:

[0032] The collection box is placed at the bottom of the filter bucket;

[0033] The filter layer consists of several layers.

[0034] The air intake pipe is equipped with a guide pipe connected to the filter barrel, and the purification barrel is equipped with an air jet pipe connected to the filter barrel.

[0035] The filter layer uses multiple filtration layers such as filter screen, activated carbon filter layer, and zeolite filter layer. Larger dust and impurities enter the filter barrel and are collected by the collection box. The filter barrel and the purification barrel are connected by a guide pipe and an air jet pipe. The guide pipe introduces the exhaust gas from the air inlet pipe, and the air jet pipe improves the uniformity of the gas introduced into the purification barrel.

[0036] The beneficial effects of this application are:

[0037] 1. The filtration mechanism filters the flocculent material in the purification tank. By generating water flow in the filtration mechanism, the water in the purification tank is filtered through the filtration mechanism, ensuring the stability of the flocculent material in the purification tank.

[0038] 2. When the flocculent material enters the first filter hood, it is intercepted. The intercepted flocculent material and a small amount of water enter the filtration mechanism, keeping the water volume in the purification tank constant and ensuring the stability of the purification performance in the purification tank.

[0039] 3. The exhaust gas introduced into the intake pipe has a high temperature, which is used to improve the energy utilization rate through a heat exchange mechanism. Attached Figure Description

[0047] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0048] Example 1:

[0049] like Figures 1-4 As shown in the figure, this application provides a waste gas treatment and recovery device based on air pollution prevention and control, including:

[0050] The purification tank 100 is equipped with an air inlet 110 and an air outlet 120;

[0051] A filter canister 200 is placed on one side of the purification canister 100 and connected to the purification canister 100. An ultraviolet lamp 210 is installed inside the filter canister 200.

[0052] An air intake pipe 300 is connected to an air intake port 110, and the air intake pipe 300 is spiral in shape;

[0053] The filter unit 400 is installed on the purification tank 100;

[0054] A stirring mechanism 500 is installed in a purification tank 100;

[0055] The filtration mechanism 400 includes a filter housing 410, a filter screen 420, a first connecting pipe 430, and a second connecting pipe 440. The filter screen 420 is placed inside the filter housing 410. The first connecting pipe 430 and the second connecting pipe 440 are both connected between the purification tank 100 and the filter housing 410. The first connecting pipe 430 is connected to the top of the filter housing 410, and the second connecting pipe 440 is connected to the bottom of the filter housing 410. The connection position between the first connecting pipe 430 and the purification tank 100 is higher than the connection position between the second connecting pipe 440 and the purification tank 100.

[0056] The purification tank 100 introduces waste gas through the air inlet 110, which is connected to the air inlet pipe 300, allowing the waste gas to be transported along the air inlet pipe 300 to the filter tank 200. The filter tank 200 filters dust and other impurities, and then the ultraviolet lamp 210 achieves rapid sterilization. It also has a strong ability to oxidize and decompose organic molecules, including malodorous substances. The waste gas is then transported back to the purification tank 100, where it flocculates. The flocculated material in the purification tank 100 is filtered by the filtration mechanism 400. The stirring mechanism 500 improves the flocculation efficiency. The filtration mechanism 400 is connected to the filter housing 410 through the first connecting pipe 430 and the second connecting pipe 440. Water flow is generated in the filtration mechanism 400, allowing the water in the purification tank 100 to be filtered through the filtration mechanism 400. The flocculated material is filtered through the filter screen 420. The filter housing 410 is installed on the outer wall of the purification tank 100 by fasteners.

[0057] Furthermore, the filtration mechanism 400 is provided with a first filter cover 450, which corresponds to the first connecting pipe 430.

[0058] The first filter cover 450 is installed on the inner wall of the purification tank 100, and its opening faces the opposite direction to the rotation direction of the stirring mechanism 500. When the flocculent material enters the first filter cover 450, it is intercepted. The intercepted flocculent material and a small amount of water enter the filtration mechanism 400, which keeps the water volume in the purification tank 100 constant, ensures the stability of the purification performance in the purification tank 100, and avoids large-scale replacement of the water in the purification tank 100, thereby improving water conservation.

[0059] Furthermore, a drain outlet 411 is provided at one end of the filter housing 410.

[0060] The drain outlet 411 facilitates the discharge of highly concentrated flocculent material from the filter housing 410, ensuring the filtration stability of the filter mechanism 400 and the ease of discharging the flocculent material.

[0061] Furthermore, both the second connecting pipe 440 and the first connecting pipe 430 are provided with a heat exchange mechanism 460, the heat exchange mechanism 460 including:

[0062] The heat exchange shell 461 is respectively installed on the first connecting pipe 430 and the second connecting pipe 440;

[0063] Spiral blade 462 is installed inside heat exchange housing 461;

[0064] Water inlet pipe 463 is connected to heat exchange shell 461 corresponding to the second connecting pipe 440;

[0065] Water outlet pipe 464 is connected to heat exchange shell 461 corresponding to the first connecting pipe 430;

[0066] The two heat exchange shells 461 are interconnected.

[0067] The exhaust gas introduced into the intake pipe 300 has a high temperature. The heat exchange mechanism 460 is used to improve the energy utilization rate. When the water in the purification tank 100 flows through the first connecting pipe 430 and the second connecting pipe 440, heat exchange occurs through the heat exchange mechanism 460. The heat exchanged is used for other equipment or for power generation. The heat exchange medium flows in from the inlet pipe 463 and flows out from the outlet pipe 464. The heat exchange shell 461 and the spiral blades 462 increase the heat exchange efficiency between the heat exchange medium and the first connecting pipe 430 and the second connecting pipe 440, respectively.

[0071] Spray pipe 140 is installed on purification tank 100 and connected to water pump 130;

[0072] The second filter cover 150 is installed at the connection between the water pump 130 and the purification tank 100;

[0073] The connection point between the second connecting pipe 440 and the purification tank 100 corresponds to the second filter cover 150.

[0074] Water is drawn from the purification tank 100 by the water pump 130 and then sprayed out from the spray pipe 140. The decomposed organic molecules in the exhaust gas entering the purification tank 100 are dissolved in the water. The second filter cover 150 ensures that the water pump 130 draws clean water. The second filter cover 150 corresponds to the second connecting pipe 440, so that the water flushed out of the second connecting pipe 440 acts on the second filter cover 150, reducing the adhesion of flocculent substances on the filter cover.

[0075] Furthermore, the filter cartridge 200 includes:

[0076] Collection box 220 is placed at the bottom of filter bucket 200;

[0077] Filter layer 230, consisting of several layers;

[0078] The air intake pipe 300 is provided with a guide pipe 310 connected to the filter barrel 200, and the purification barrel 100 is provided with a jet pipe 160 connected to the filter barrel 200.

[0079] The filter layer 230 uses multiple filter layers 230, such as filter screen 420 plate, activated carbon filter layer 230, and zeolite filter layer 230, for filtration. Larger dust and impurities enter the filter barrel 200 and are collected by the collection box 220. The filter barrel 200 and the purification barrel 100 are connected by a guide pipe 310 and an air jet pipe 160. The guide pipe 310 introduces the exhaust gas from the air inlet pipe 300, and the air jet pipe 160 improves the uniformity of the gas introduced into the purification barrel 100.
