Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a dust removal and dehumidification device for industrial waste gas treatment. Background Technology

[0002] With the acceleration of industrialization, industries such as chemical, metallurgical, and building materials emit large amounts of industrial waste gas during production. A search revealed Chinese patent CN222752856U, which discloses a dust removal and dehumidification device for industrial waste gas treatment. This device includes a support box with a purification chamber fixedly connected to its inner wall. An induced draft fan is fixedly connected to the left side of the support box, and a stirring mechanism is installed on top of the fan. An air inlet pipe is fixedly connected to the right side of the support box, and a cleaning mechanism is installed on the back of the support box. A guide ramp is fixedly connected to the inner wall of the support box. This dust removal and dehumidification device, through its cleaning mechanism, can move the filtered particles on the filter frame, allowing them to be discharged into the collection box. This achieves the purpose of collecting the particles, reducing clogging of the filter frame during filtration, further improving filtration smoothness, and ensuring the continued operation of the filtration process. Simultaneously, opening the sealed door on the front of the support box and pulling out the collection box allows for the removal of the cleaned particles.

[0003] The dust removal and dehumidification equipment for industrial waste gas treatment in the aforementioned patent has the following shortcomings: Due to the continuous rotation of the output shaft through the cleaning mechanism, the cleaning block will move back and forth. The cleaning block in the reciprocating motion can push the filtered particles on the filter frame to move, so that the filtered particles can be discharged into the inside of the collection box, thereby achieving the purpose of collecting particles and reducing the clogging of the filter frame during the filtration process. However, since the dust particles in the waste gas are extremely small, the reciprocating movement of the cleaning block on the filter frame can easily cause dust to clog the filter frame. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust removal and dehumidification device for industrial waste gas treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial waste gas treatment dust removal and dehumidification device includes a waste gas treatment box. A top plate is fixedly connected to one side of the inner wall of the waste gas treatment box near the top, and a second baffle is fixedly connected to the bottom of the top plate near the edge of the waste gas treatment box. A first baffle is fixedly connected to the other end of the top plate. A third baffle is fixedly connected to the bottom of the inner side of the waste gas treatment box, with the top of the third baffle located between the first and second baffles and the bottom of the third baffle not in contact with the bottom of the waste gas treatment box. A horizontal pipe is fixedly connected between the two sides of the waste gas treatment box, and multiple atomizing nozzles are fixedly connected at equal intervals at the bottom of the horizontal pipe. The horizontal pipe is located between the first and second baffles and at the bottom of the top plate. Through the arrangement of the first, second, and third baffles, the waste gas needs to pass through water twice before it can be discharged, which facilitates the combination of dust and water and achieves the dust removal effect.

[0007] Preferably, a metal mesh plate is fixedly connected to the inner wall of the exhaust gas treatment box at the top of the top plate, and a honeycomb activated carbon block is placed on top of the metal mesh plate. An inspection door is provided on the outer wall of the exhaust gas treatment box near the honeycomb activated carbon block. The inspection door allows for the maintenance and replacement of the honeycomb activated carbon block. The honeycomb activated carbon block can dehumidify the exhaust gas and also adsorb harmful substances.

[0008] Preferably, the top of the waste gas treatment box is provided with an air outlet, and an exhaust fan is fixedly installed at the air outlet.

[0009] Preferably, an air inlet pipe is fixedly connected to the outer wall of the exhaust gas treatment box near the second baffle, and the air inlet pipe is located at the bottom of the top plate. A sewage pipe is fixedly connected to the bottom of the same side of the outer wall of the exhaust gas treatment box, and a control valve is fixedly installed on the sewage pipe.

[0010] Preferably, an external water tank is fixedly connected to the side of the outer wall of the exhaust gas treatment box away from the sewage pipe, and a connection hole is opened at the bottom of the side of the external water tank near the exhaust gas treatment box, and the connection hole is connected to the exhaust gas treatment box. A water level detector is fixedly installed at the top of the inner wall of the external water tank. The water level detector can monitor the change of the liquid level inside the exhaust gas treatment box in real time to ensure normal operation.

[0011] Preferably, a circulation pump is fixedly connected to one side of the outer wall of the exhaust gas treatment box, and a water suction pipe is fixedly connected to the input end of the circulation pump. The other end of the water suction pipe passes through the bottom of the exhaust gas treatment box, and a filter screen is fixedly connected to the water suction pipe inside the exhaust gas treatment box. A water delivery pipe is fixedly connected to the output end of the circulation pump, and the other end of the water delivery pipe passes through the exhaust gas treatment box and is fixedly connected to one end of the horizontal pipe. The circulation pump can continuously deliver water from the bottom of the exhaust gas treatment box to the horizontal pipe, so that the water mist sprayed from the atomizing nozzle can carry the dust in the exhaust gas into the water.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing technologies such as a top plate, first baffle, second baffle, third baffle, honeycomb activated carbon blocks, and atomizing nozzles, the exhaust gas entering the waste gas treatment chamber is guided by the first, second, and third baffles, requiring it to pass underwater twice. This allows dust in the exhaust gas to easily combine with water and remain in the water. Simultaneously, the water mist sprayed from the atomizing nozzles further carries the dust and dissolves it in the water, improving dust removal efficiency. At the same time, the honeycomb activated carbon blocks can dehumidify the exhaust gas after dust removal and adsorb harmful substances, effectively solving the problem of poor dust removal mentioned in the background technology. This achieves full contact and combination between dust and water, and the water mist sprayed from the atomizing nozzles further captures and dissolves the dust, significantly improving dust removal and dehumidification efficiency. It can effectively remove dust particles of different sizes from the exhaust gas, deeply purify industrial waste gas, and ensure that the emitted gas meets environmental protection standards.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4A dust removal and dehumidification device for industrial waste gas treatment includes a waste gas treatment box 1. A top plate 9 is fixedly connected to one side of the inner wall of the waste gas treatment box 1 near the top, and a second baffle 902 is fixedly connected to the bottom of the top plate 9 near the edge of the waste gas treatment box 1. A first baffle 901 is fixedly connected to the other end of the top plate 9. A third baffle 903 is fixedly connected to the bottom of the inner side of the waste gas treatment box 1, with the top of the third baffle 903 located between the first baffle 901 and the second baffle 902, and the bottom of the third baffle 903 not in contact with the bottom of the waste gas treatment box 1. The exhaust gas treatment box 1 is fixedly connected to the same horizontal pipe 10 on both sides, and multiple atomizing nozzles 1001 are fixedly connected at equal intervals at the bottom of the horizontal pipe 10. The horizontal pipe 10 is located between the first baffle 901 and the second baffle 902 and at the bottom of the top plate 9. Through the arrangement of the top plate 9, the first baffle 901, the second baffle 902 and the third baffle 903, the exhaust gas needs to cross the water surface twice after entering the exhaust gas treatment box 1, so that the dust can be left in the water. At the same time, the operation of the atomizing nozzles 1001 improves the dust removal efficiency.

[0021] In this utility model, a metal mesh plate 8 is fixedly connected to the inner wall of the exhaust gas treatment box 1 at the top of the top plate 9, and a honeycomb activated carbon block 801 is placed on the top of the metal mesh plate 8. An inspection door 2 is provided on the outer wall of the exhaust gas treatment box 1 near the honeycomb activated carbon block 801. The honeycomb activated carbon block 801 can absorb moisture and harmful substances in the exhaust gas.

[0022] In this utility model, the top of the exhaust gas treatment box 1 is provided with an air outlet, and an exhaust fan 3 is fixedly installed at the air outlet. The exhaust fan 3 can provide negative pressure inside the exhaust gas treatment box 1 to ensure the flow of exhaust gas.

[0023] In this utility model, an air inlet pipe 5 is fixedly connected to the outer wall of the exhaust gas treatment box 1 near the second baffle 902, and the air inlet pipe 5 is located at the bottom of the top plate 9. A sewage pipe 6 is fixedly connected to the bottom of the same side of the outer wall of the exhaust gas treatment box 1, and a control valve 601 is fixedly installed on the sewage pipe 6. The sewage pipe 6 can discharge the wastewater inside the exhaust gas treatment box 1.

[0024] In this utility model, an outer water tank 4 is fixedly connected to the side of the outer wall of the exhaust gas treatment box 1 away from the sewage pipe 6, and a connection hole 402 is opened at the bottom of the side of the outer water tank 4 close to the exhaust gas treatment box 1, and the connection hole 402 is connected to the exhaust gas treatment box 1. A water level detector 401 is fixedly installed at the top of the inner wall of the outer water tank 4. The water level detector 401 can detect changes in liquid level and remind the user to add water in time to avoid affecting the dust removal effect.

[0025] In this utility model, a circulation pump 7 is fixedly connected to one side of the outer wall of the exhaust gas treatment box 1, and a water pump 701 is fixedly connected to the input end of the circulation pump 7. The other end of the water pump 701 passes through the bottom of the exhaust gas treatment box 1, and a filter screen is fixedly connected to the water pump 701 inside the exhaust gas treatment box 1. A water supply pipe 702 is fixedly connected to the output end of the circulation pump 7, and the other end of the water supply pipe 702 passes through the exhaust gas treatment box 1 and is fixedly connected to one end of the horizontal pipe 10. Through the arrangement of the circulation pump 7, the water pump 701, and the water supply pipe 702, water can be continuously supplied to the horizontal pipe 10.

[0026] Working principle: The top of the third baffle 903 is higher than the bottom of the two second baffles 902 by a certain distance. The first baffle 901 and the second baffle 902 are the same size. The first baffle 901, the third baffle 903, and the second baffle 902 are interleaved. In use, the air inlet pipe 5 is connected to the exhaust pipe, and water is added to the outer water tank 4. Under the action of the connection hole 402, the outer water tank 4 and the exhaust gas treatment box 1 form a communicating vessel. The liquid level inside the outer water tank 4 is the same as the liquid level inside the exhaust gas treatment box 1. The water level gauge 401 ensures that the liquid level inside the exhaust gas treatment box 1 is slightly higher than the bottom of the second baffle 902 and the first baffle 901, thus dividing the interior of the exhaust gas treatment box 1 into three spaces. The exhaust fan 3 is then turned on, creating negative pressure inside the exhaust gas treatment box 1. Due to the low position of the connection hole 402, the water pressure at that location is high, preventing external air from entering the exhaust gas treatment box 1 through the connection hole 402. Consequently, the exhaust gas enters the exhaust gas treatment box 1 through the inlet pipe 5, passes through the bottom of the second baffle 902, and enters the third space. In the space enclosed by the first baffle 901, the top plate 9, and the second baffle 902, the exhaust gas passes through the bottom of the first baffle 901, enters the metal mesh plate 8 and the honeycomb activated carbon block 801, and is then discharged. The exhaust gas enters the exhaust fan 3 from the inlet pipe 5 and needs to pass through water twice. During this process, dust particles in the waste dissolve in the water. Simultaneously, the circulation pump 7 is activated, drawing water from the bottom of the exhaust gas treatment box 1 to the horizontal pipe 10, where it is sprayed out through the atomizing nozzle 1001, further atomizing the dust in the exhaust gas. Combined with water mist, the water falls into the water at the bottom of the exhaust gas treatment box 1, effectively treating the dust in the exhaust gas. When the exhaust gas passes through the honeycomb activated carbon block 801, moisture and other harmful substances can be absorbed by the honeycomb activated carbon block 801 before being discharged. The water level detector 401 can detect changes in the liquid level. When the liquid level drops, the user needs to be reminded to replenish the water in time. When there is a lot of water and dust at the bottom of the exhaust gas treatment box 1, the water inside the exhaust gas treatment box 1 can be drained by opening the control valve 601 and replaced.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
