[0002] With the continuous development of society and the continuous progress of science and technology, people have been making unremitting efforts for environmental protection. During daily use, smoke is emitted into the air. This includes smoke and dust generated from the combustion of fuels and other substances, as well as smoke and dust generated from mechanical processes such as crushing, screening, and conveying of solid materials. Dust removal is the process of separating these particles from the smoke and dust and collecting and recycling them.

[0003] Existing technologies for flue gas dust removal mostly rely on activated carbon to absorb and remove harmful substances in the flue gas. This results in a relatively simple dust removal effect and easily leads to the release of harmful elements from the flue gas into the air. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, most flue gas dust removal methods rely on activated carbon to absorb and clean harmful substances in the flue gas, resulting in a relatively simple flue gas dust removal effect and easily causing harmful elements in the flue gas to be released into the air. Therefore, this utility model proposes a flue gas dust removal device for air pollution prevention and control.

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

[0006] A flue gas dust removal device for air pollution control includes an exhaust chamber and a connecting chamber. The upper end of the exhaust chamber is fixedly connected to the connecting chamber, and the end of the connecting chamber away from the exhaust chamber is fixedly connected to an air inlet chamber.

[0007] A dust removal component is installed between the air inlet chamber and the exhaust chamber. The dust removal component includes a sliding plate, an airbag, a support plate, a water flow chamber, and a collection chamber. The two ends of the sliding plate are slidably connected to both sides of the exhaust chamber. The airbag is fixedly connected between the sliding plate and the outer surface of the connecting chamber. The support plate is fixedly connected inside the exhaust chamber. Multiple spray nozzles are connected to the inner wall of the support plate. The water flow chamber is fixedly connected to the support plate. An air vent is opened at the upper end of the water flow chamber. The collection chamber is fixedly connected to the exhaust chamber and is connected to the water flow chamber. The airbag is connected to the multiple spray nozzles through a water delivery chamber.

[0008] Preferably, the dust removal component further includes a water storage chamber and a water inlet pipe. The water storage chamber is fixedly connected to the upper end of the air inlet chamber, and the water inlet pipe is fixedly connected between the water storage chamber and the air bladder. The water inlet pipe is slidably connected to the slide plate, and a one-way valve is installed on both the water inlet pipe and the water delivery chamber.

[0009] Preferably, a spring is fixedly connected between the sliding plate and the outer wall of the communicating cavity.

[0010] Preferably, a filter chamber is slidably connected inside the discharge chamber, and the filter chamber is filled with activated carbon.

[0011] Preferably, a semi-circular cavity is fixedly connected to the air intake chamber, and a rotating rod is rotatably connected to the semi-circular cavity. Multiple fan blades are arranged in a ring on the rotating rod.

A cam is fixedly connected to the rotating shaft, and a transmission belt is sleeved between the rotating shaft and the rotating rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A flue gas dust removal device for air pollution control includes an exhaust chamber 1 and a connecting chamber 6. The lower end of the exhaust chamber 1 is not sealed, allowing the treated flue gas to be discharged. The upper end of the exhaust chamber 1 is fixedly connected to the connecting chamber 6. The end of the connecting chamber 6 away from the exhaust chamber 1 is fixedly connected to an air inlet chamber 11. A semi-circular cavity 12 is fixedly connected to the air inlet chamber 11. A rotating rod 19 is rotatably connected to the semi-circular cavity 12. Multiple fan blades 20 are arranged in a ring on the rotating rod 19. There are multiple fan blades 20, some of which are located in the semi-circular cavity 12 and some of which are located in the air inlet chamber 11. Two protrusions are provided at the upper end of the air inlet chamber 11. A rotating shaft 16 is rotatably connected between the two protrusions. A cam 14 is fixedly connected to the rotating shaft 16. A transmission belt 13 is sleeved between the rotating shaft 16 and the rotating rod 19. A filter chamber 2 is slidably connected inside the exhaust chamber 1. The filter chamber 2 is filled with activated carbon.

[0024] A dust removal component is installed between the air intake chamber 11 and the exhaust chamber 1. The dust removal component includes a slide plate 4, an airbag 8, a support plate 5, a water flow chamber 18, and a collection chamber 3. The two ends of the slide plate 4 are slidably connected to both sides of the exhaust chamber 1. A spring 15 is fixedly connected between the slide plate 4 and the outer wall of the connecting chamber 6. The airbag 8 is fixedly connected between the slide plate 4 and the outer surface of the connecting chamber 6. The support plate 5 is fixedly connected inside the exhaust chamber 1. Multiple spray nozzles 17 are connected to the inner wall of the support plate 5. The spray nozzles 17 are horizontally arranged and can spray the medicine in an atomized form, which falls onto the support plate. 5. The water flow chamber 18 is fixedly connected to the support plate 5. The upper end of the water flow chamber 18 is provided with an air vent. The collection chamber 3 is fixedly connected to the discharge chamber 1 and is connected to the water flow chamber 18. The air bag 8 is connected to multiple spray nozzles 17 through the water delivery chamber 7. The dust removal component also includes a water storage chamber 10 and a water inlet pipe 9. The water storage chamber 10 is fixedly connected to the upper end of the air inlet chamber 11. The water inlet pipe 9 is fixedly connected between the water storage chamber 10 and the air bag 8. The water inlet pipe 9 is slidably connected to the slide plate 4. A one-way valve is installed on both the water inlet pipe 9 and the water delivery chamber 7.

[0025] In this invention, during use, the flue gas is first pressurized and flows into the discharge chamber 1 through the air inlet chamber 11 and the connecting chamber 6. It then passes through the water flow chamber 18 and the filter chamber 2 before being discharged from the lower end of the discharge chamber 1. During the process of passing through the filter chamber 2, the dust and harmful substances in the flue gas are adsorbed by the activated carbon, thus achieving the effect of safe emission of the flue gas after dust removal.

[0026] When the flue gas passes through the intake chamber 11, it pushes the fan blade 20 to move and drives the rotating rod 19 to rotate clockwise. The rotating shaft 16 also rotates clockwise through the transmission belt 13. When the cam 14 rotates with the rotating shaft 16, it can squeeze the slide plate 4 to move to the right and compress the spring 15. When the slide plate 4 moves to the right, it can compress the air bag 8. At this time, the one-way valve on the water inlet pipe 9 is closed, and the one-way valve on the water delivery chamber 7 is opened. The water in the air bag 8 is sprayed out from the spray nozzle 17 onto the support plate 5 through the water delivery chamber 7. When the cam 14 is not pressing the slide plate 4, the slide plate 4 returns to its original position under the elastic force of the spring 15 and stretches the air bag 8. At this time, the one-way valve on the water inlet pipe 9 opens and the one-way valve on the water delivery chamber 7 closes. As the slide plate 4 moves horizontally back and forth continuously, the medicine in the water storage chamber 10 can be sprayed into the tray 5, which can cool and reduce dust in the flue gas passing through the tray 5 and the water flow chamber 18. At the same time, the alkaline substances in the medicine can neutralize the acidic gases in the flue gas.

[0027] The liquid medicine on the tray 5 can flow into the water flow chamber 18, and then into the collection chamber 3. The gas will enter the water flow chamber 18 along with the liquid medicine. After fully reacting, it can be discharged through the vent on the upper side of the water flow chamber 18 and then pass through the filter chamber 2 for activated carbon adsorption of impurities. Finally, it is discharged through the bottom of the discharge chamber 1.

[0029] 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.
