[0004] During the use of the purification equipment for air pollution control disclosed in the application, since the air entering the purification box 1 passes through the gas uniform distribution plate 1 from bottom to top, large particles of impurities are more likely to be intercepted and adhered to the bottom of the gas uniform distribution plate 1, and the cleaning plate has a smaller cleaning effect on the gas uniform distribution plate 1, and the nozzles 1 and 2 are mainly used to spray desulfurization solution, and are difficult to be used to flush the air outlet on the gas uniform distribution plate 1.

DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] See also Figure 1-6 As shown, in this embodiment, a purification device for air pollution control is provided, including a purification box 1, one side of the purification box 1 is connected to an air intake component, and the other side is connected to an exhaust pipe 101 and a sewage discharge component. A filter component, a brushing component corresponding to the filter component, and a control and discharge component are arranged in the purification box 1, and the brushing component is located below the filter component;

[0034] A motor 13 is installed on one side of the purification box 1. The motor 13 is located between the air intake assembly and the exhaust pipe 101. The output shaft of the motor 13 is fixedly connected to a rotating column 1301. The end of the rotating column 1301 is connected to a rotating drum 14 that is rotatably matched in the purification box 1. The rotating drum 14 and the exhaust pipe 101 are both located above the filter assembly. A liquid supply assembly connected to the rotating drum 14 is connected to the side of the purification box 1 away from the motor 13. A plurality of flushing nozzles 15 and a plurality of aerosol nozzles 16 are connected to the side of the rotating drum 14. The flushing nozzles 15 are located above the aerosol nozzles 16. An electric push rod 17 is installed in the rotating column 1301. The electric push rod 17 The output shaft 17 is fixedly connected to a connecting plate 1701 located in the rotating drum 14, and extension plates 1702 are respectively provided at both ends of the connecting plate 1701. A plurality of arc-shaped baffles 1703 are provided on the upper and lower sides of the two extension plates 1702. The flushing nozzles 15 are located on the side of the corresponding arc-shaped baffles 1703, and the aerosol nozzles 16 are located on one side of the corresponding arc-shaped baffles 1703, wherein the flushing nozzles 15 are in a single row and the aerosol nozzles 16 are in three rows. The flushing nozzles 15 can be used to spray high-pressure water columns to flush the filter components, and the aerosol nozzles 16 can be used to spray mist-like desulfurization solution to fill the purification box 1 and wait for it to react with sulfur dioxide in the air.

[0035] The application of one aspect of this embodiment is as follows: during purification operation, the liquid supply component works to pump the desulfurization solution into the drum 14, and then the desulfurization solution is sprayed out in a mist form through the aerosol nozzle 16. At the same time, the air intake component works to pump air into the bottom of the inner cavity of the purification box 1, and then the air is discharged from the exhaust pipe 101 after filtering dust and impurities through the filter component. During this process, the air fully contacts and reacts with the mist-like desulfurization solution; and when the filter component needs to be cleaned, the electric push rod 17 extends to push the connecting plate 1701, the extension plate 1702 and the arc baffle 1703 to move a certain distance, so that the arc baffle 1703 located below blocks the aerosol nozzle 16, and the arc baffle 1703 located above cancels the flushing. The nozzle 15 is blocked, and then the motor 13 drives the rotating column 1301, the rotating drum 14, the flushing nozzle 15 and the aerosol nozzle 16 to rotate 180 degrees, so that the flushing nozzle 15 is facing downward. At this time, the liquid supply component works to pump clean water into the rotating drum 14, and then the clean water is sprayed out through the flushing nozzle 15 to flush the filter component. At this time, the motor 13 works to drive the flushing nozzle 15 to swing back and forth within a certain angle range, and at the same time controls the brushing component to brush the bottom of the filter component. After the brushing is completed, the control and discharge component is shifted open, so that the water on the filter component flushed by the flushing nozzle 15 can also flow down from the side of the filter component, and the flushed sewage and the desulfurization solution after failure can be controlled and discharged from the sewage discharge component.

[0036] The connecting plate 1701, the extension plate 1702 and the arc baffle 1703 are moved by the extension and retraction of the electric push rod 17, so that the arc baffle 1703 can be adjusted to block the aerosol nozzle 16 or the flushing nozzle 15, and the motor 13 can be used to drive the drum 14 to rotate, so that the aerosol nozzle 16 can be used to evenly spray the desulfurization solution, and the flushing nozzle 15 can be used to flush the top and mesh of the filter component, and at the same time, the dust and impurities adhered to the bottom of the filter component can be scrubbed in cooperation with the brushing component, thereby improving the efficiency and cleanliness of the cleaning of the filter component, thereby extending the interval time of the cleaning of the filter component and reducing the cleaning frequency.

[0037] like Figure 6 As shown, in this embodiment, two grooves are provided on the inner wall side of the rotating drum 14, and a sliding bar that slides in the groove is provided on the side of the extension plate 1702. The sliding direction and distance of the extension plate 1702 are limited by the cooperation between the groove and the sliding bar, thereby improving the stability of the extension plate 1702 and the arc baffle 1703 when sliding.

The end of the rotating drum 14 away from the rotating column 1301 is rotatably matched on the peripheral side of the extension cylinder. The peripheral side of the extension cylinder is provided with a ring plate located in the rotating drum 14. The upper part of the L-shaped return pipe 1801 is connected to the side of the liquid supply pipe 18. The L-shaped return pipe 1801 The lower part is connected with the bottom of the inner cavity of the purification box 1, a valve 1 20 is arranged on the L-shaped reflux pipe 1801, a water pump 19 and a valve 2 21 are arranged on the liquid supply pipe 18, the water pump 19 is located between the purification box 1 and the valve 2 21, the upper part of the L-shaped reflux pipe 1801 is located between the water pump 19 and the valve 2 21, the liquid supply pipe 18 is connected to a water storage container and a desulfurization solution storage container through a three-way valve, and a sulfur dioxide detector is installed on the inner wall of the exhaust pipe 101. When in use, close the valve One 20, open valve two 21, and control the three-way valve to connect the liquid supply pipe 18 with the desulfurization solution storage container, and then the water pump 19 works to pump the desulfurization solution into the drum 14; and when a certain amount of desulfurization solution exists at the bottom of the inner cavity of the purification box 1, open valve one 20, close valve two 21, and the water pump 19 works to pump the desulfurization solution at the bottom of the inner cavity of the purification box 1 into the drum 14 again through the L-shaped reflux pipe 1801, thereby achieving full utilization of the desulfurization solution and reducing waste; a sulfur dioxide detector can be used to detect the sulfur dioxide concentration in the exhaust air to reflect the effectiveness of the desulfurization solution in the purification box 1. After the desulfurization solution in the purification box 1 fails, the sewage discharge component is controlled to open and discharge it, and then the above operation is repeated to inject new desulfurization solution; the stability of the drum 14 during rotation is improved by the extension drum, the drum 14 is restricted from detaching from the extension drum by the ring plate, and the probability of the liquid in the drum 14 flowing out from the gap between the drum 14 and the extension drum is reduced.
