[0029] 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.

[0030] Please see Figure 1-8 In this embodiment of the utility model, an energy-saving waste gas dust removal and environmental protection equipment includes a dust removal box body 1, a dust removal device 2 is installed on the upper end of the dust removal box body 1, and one side is connected to an adsorption device 3; the other side of the adsorption device 3 is connected to an emission device 4.

[0031] The dust removal device 2 includes a mounting frame 21, which is fixedly mounted on the upper surface of the outer frame 17. The upper end of the mounting frame 21 is fixedly connected to the air tank 22. A plurality of electromagnetic pulse valves 23 are connected in a rectangular array on one side of the air tank 22. Each electromagnetic pulse valve 23 is connected to a blow pipe 24 at its end. The lower end of each blow pipe 24 is provided with a plurality of venturi tubes 26. The plurality of venturi tubes 26 are fixedly mounted on the fixing plate 25, and each venturi tube 26 is connected to a filter bag 27 at its lower end.

[0032] By adopting the above technical solution, the dust removal device 2 uses a combination of filter bag 27 and electromagnetic pulse cleaning. The filter bag 27 can effectively intercept a large amount of dust, while the cleaning system composed of electromagnetic pulse valve 23, air tank 22, blow pipe 24 and venturi tube 26 can remove the dust accumulated on the surface of filter bag 27 in a timely manner, ensuring that filter bag 27 is always in a high-efficiency filtration state. The electromagnetic pulse cleaning system uses compressed air to remove dust by instantaneous blowing, which reduces the operating energy consumption of the equipment compared with continuous mechanical vibration cleaning. The air tank 22 stores compressed air and releases it in a concentrated manner when cleaning is required, avoiding continuous energy consumption and effectively reducing the operating cost of the equipment.

[0033] In this embodiment, the fixing plate 25 is installed inside the dust collector 16, the bottom of the dust collector 16 is fixedly connected to the ash hopper 13, and dust inlets 12 and maintenance doors 15 are installed on both sides of the ash hopper 13, while the bottom is equipped with an ash discharge valve 14; both the dust collector 16 and the ash hopper 13 are installed on the base frame 11.

[0034] The dust collector 16 is equipped with an outer frame 17 on the outside and a top cover 18 on the top. One side of the upper end of the dust collector 16 is connected to the dust collector 16, and the other end of the dust collector 16 is fixedly connected to the connecting pipe 110. A controller 111 is also installed on the same side of the upper end of the dust collector 16.

[0035] By adopting the above technical solutions, the base frame 11 and the outer frame 17 provide a stable support structure for the equipment, ensuring that the equipment remains stable during operation. The dust removal and environmental protection equipment adopts a modular design as a whole. The dust removal box body 1, dust removal device 2, adsorption device 3 and emission device 4 are independent of each other but closely connected. This design facilitates the transportation, installation and commissioning of the equipment, and can be flexibly combined according to the needs and spatial layout of different industrial sites, thus improving the applicability of the equipment.

[0036] In this embodiment, the other end of the connecting pipe 110 is fixedly connected to the air filter inlet 33. The air filter inlet 33 is installed at one end of the filter box 32, and the other end of the filter box 32 is equipped with an air filter outlet 34. The filter box 32 is installed on the support leg 31, and the upper surface of the filter box 32 is provided with multiple top maintenance doors 37.

[0037] The filter box 32 has symmetrically arranged dust collection hoppers 35 at the bottom of its inner side, and each dust collection hopper 35 has a dust discharge port 36 installed at the bottom. The filter box 32 has multiple activated carbon filter plates 38 arranged in a rectangular array inside its inner side. The upper end of the activated carbon filter plates 38 is connected to the inner side of the filter box 32, and the bottom is fixedly connected to the dust collection hoppers 35.

[0038] By adopting the above technical solution, the activated carbon filter plates 38 in the adsorption device 3 are arranged in a rectangular array, which increases the contact area and contact time between the waste gas and the activated carbon filter plates 38, and can fully adsorb the residual harmful gases and fine particles in the waste gas, thereby achieving deep purification of the waste gas and enabling the waste gas emissions to meet higher environmental protection standards. The multiple top maintenance doors 37 set on the filter box 32 facilitate the staff to inspect, replace and maintain the activated carbon filter plates 38, ensuring the normal operation of the equipment.

[0039] In this embodiment, the air outlet 34 is fixedly connected to the connecting pipe 41, the other end of the connecting pipe 41 is fixedly connected to the fan 42, and the other end of the fan 42 is fixedly connected to the air outlet pipe 44; the fan 42 and the air outlet pipe 44 are respectively connected to the bottom and top of the fixing frame 43.

[0040] By adopting the above technical solution, the fan 42 and the exhaust pipe 44 in the emission device 4 are securely installed by the fixing frame 43, ensuring that the fan 42 and the exhaust pipe 44 can work stably during the operation of the equipment, avoiding gas leakage or unstable transmission caused by factors such as vibration, and ensuring stable emission of exhaust gas.

[0041] The working principle of this utility model is as follows: When the exhaust gas containing dust and pollutants enters the ash hopper 13 from the dust inlet 12, due to the sudden decrease in airflow speed, the larger dust particles will directly settle to the bottom of the ash hopper 13 under the action of gravity. Subsequently, the dust-laden exhaust gas rises into the dust collection box 16. In the dust collection box 16, the exhaust gas passes through the filter bag 27, and the dust is intercepted on the surface of the filter bag 27. The purified gas then passes through the filter bag 27 and enters the space above.

[0042] As the filtration process proceeds, dust accumulates on the surface of the filter bag 27, affecting the filtration effect. At this time, the controller 111 sends a signal to trigger the electromagnetic pulse valve 23 to open. Compressed air in the air tank 22 is injected into the filter bag 27 at high speed through the blow pipe 24 and the venturi tube 26, causing the filter bag 27 to expand instantly and shake, shaking the dust on the surface into the ash hopper 13, and then discharged through the ash discharge valve 14.

[0043] After the gas has undergone preliminary dust removal by the filter bag 27, it enters the filter box 32 through the connecting pipe 110. Inside the filter box 32, the gas passes through the activated carbon filter plate 38. The activated carbon filter plate 38 can adsorb harmful gases and remaining fine particles in the exhaust gas, further purifying the gas. The purified gas enters the fan 42 from the filter outlet 34 through the connecting pipe 21. Under the action of the fan 42, it is finally discharged through the exhaust pipe 44.

[0044] The dust removal device 2 uses a combination of filter bags 27 and electromagnetic pulse cleaning. The filter bags 27 can effectively intercept a large amount of dust, while the cleaning system composed of electromagnetic pulse valve 23, air tank 22, blow pipe 24 and venturi tube 26 can remove the dust accumulated on the surface of the filter bags 27 in a timely manner, ensuring that the filter bags 27 are always in a high-efficiency filtration state. The electromagnetic pulse cleaning system uses compressed air to remove dust by instantaneous blowing, which reduces the operating energy consumption of the equipment compared with continuous mechanical vibration cleaning. The air tank 22 stores compressed air and releases it in a concentrated manner when cleaning is required, avoiding continuous energy consumption and effectively reducing the operating cost of the equipment.

[0045] The activated carbon filter plates 38 in the adsorption device 3 are arranged in a rectangular array, which increases the contact area and contact time between the waste gas and the activated carbon filter plates 38. This allows for the full adsorption of residual harmful gases and fine particles in the waste gas, achieving deep purification of the waste gas and enabling the waste gas emissions to meet higher environmental protection standards. The multiple top maintenance doors 37 on the filter box 32 facilitate the inspection, replacement and maintenance of the activated carbon filter plates 38 by the staff, ensuring the normal operation of the equipment.

[0046] The fan 42 and the exhaust pipe 44 in the emission device 4 are securely installed by the fixing frame 43 to ensure that the fan 42 and the exhaust pipe 44 can work stably during the operation of the equipment, avoid gas leakage or unstable transmission caused by factors such as vibration, and ensure stable emission of exhaust gas.

[0047] The base frame 11 and the outer frame 17 provide a stable support structure for the equipment, ensuring that the equipment remains stable during operation. The dust removal and environmental protection equipment adopts a modular design. The dust removal box body 1, dust removal device 2, adsorption device 3 and emission device 4 are independent yet closely connected. This design facilitates the transportation, installation and commissioning of the equipment and can be flexibly combined according to the needs and spatial layout of different industrial sites, thus improving the applicability of the equipment.
