Description

Technical Field

[0001] This utility model relates to the field of sulfur dioxide treatment technology, and in particular to a sulfur dioxide filtration device. Background Technology

[0002] Sulfur dioxide, as one of the most common and simplest sulfur oxides, is colorless and transparent with a pungent odor and is one of the major air pollutants. Large amounts of sulfur dioxide are generated during industrial production processes, and many factories and enterprises use equipment to filter and purify it to reduce its pollution of the atmosphere and environment.

[0003] A search revealed a sulfur dioxide filtration device with authorization announcement number CN223096533U. This device allows for easy replacement of activated carbon adsorption plates, ensuring that the activated carbon in the plates can continue to filter sulfur dioxide, facilitating continued purification of sulfur dioxide. Furthermore, it allows for the easy removal of two sets of activated carbon adsorption plates from the filter box, while the other two sets can continue to purify sulfur dioxide inside the filter box.

[0004] Based on the aforementioned patents, it can be seen that most existing sulfur dioxide filtration devices first pre-treat sulfur dioxide using a spray method, and then filter it using activated carbon adsorption plates before discharge. Although this method can effectively treat sulfur dioxide, the water used in the spraying process cannot be recycled, resulting in a large consumption of water resources during long-term operation of the device and thus high water costs.

[0005] Therefore, it is necessary to provide a sulfur dioxide filtration device to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the technical problem that existing sulfur dioxide filtration devices cannot recycle the water used in the spraying process, resulting in high water consumption and costs during long-term operation, this utility model provides a sulfur dioxide filtration device.

[0009] Preferably, the circulating spray mechanism includes: a hollow plate fixedly installed on the inner wall of the top of the air inlet box, with a spray head provided at the bottom of the hollow plate; a partition fixedly installed on the inner wall of the air inlet box, with a bottle threadedly installed on the partition, an activated carbon adsorption layer provided inside the bottle, and a liquid outlet hole opened at the bottom of the bottle; and a water pump fixedly installed on the inner wall of the bottom of the air inlet box, with a connecting pipe fixedly installed on the discharge end of the water pump, one end of the connecting pipe extending above the partition and fixedly connected to one side of the hollow plate, and the connecting pipe communicating with the interior of the hollow plate.

[0010] Preferably, a through pipe is fixedly installed on the air intake box, one end of the through pipe extends into the interior of the filter box, and a solenoid valve is provided on the through pipe.

[0011] Preferably, an exhaust pipe and a drain pipe are fixedly installed on the filter box, the drain pipe is located below the exhaust pipe, and a valve is provided on the drain pipe.

[0012] Preferably, an addition pipe is fixedly installed on the top of the filter box, and a cover is threaded onto the addition pipe.

[0013] Preferably, the air intake box has an opening on one side, and the opening is equipped with a sealing door.

[0014] Compared with related technologies, the sulfur dioxide filtration device provided by this utility model has the following beneficial effects: This utility model provides a sulfur dioxide filtration device. The device uses an inlet pipe to allow sulfur dioxide gas to enter the inlet chamber. A circulating spray mechanism pre-treats the sulfur dioxide gas entering the inlet chamber, dissolving some of the sulfur dioxide in the water. The water used for spraying is recyclable, effectively avoiding water waste and reducing water costs over long-term use. The device exhibits good performance. A gas conveying mechanism transports the pre-treated sulfur dioxide gas to the filter chamber. After the gas enters the filter box, the activated carbon adsorption plate adsorbs and filters the sulfur dioxide, thus purifying it. At the same time, the sulfur dioxide reacts with the alkaline solution at the bottom of the filter box, further purifying it. Finally, the purified gas is discharged from the exhaust pipe. The electric slide rail can move the support block, support plate, frame, and activated carbon adsorption plate upwards. Once the frame and activated carbon adsorption plate have been moved from the top of the filter box, the frame and activated carbon adsorption plate can be removed from the support plate by simply removing the bolts, so that the activated carbon adsorption plate can be replaced.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model provides a sulfur dioxide filtration device, such as... Figure 1-3 As shown, the sulfur dioxide filtration device includes: a base plate 1, on the top of which an air inlet box 2 and a filter box 3 are fixedly installed, and an air inlet pipe 19 is provided on the air inlet box 2; a support base 4 fixedly installed on the top of the filter box 3, an electric slide rail 5 fixedly installed on one side of the support base 4, a support block 6 fixedly installed on the sliding block of the electric slide rail 5, and a support plate 7 fixedly installed at the bottom of the support block 6; a frame 9 fixedly installed on the support plate 7 by bolts 8, the frame 9 being slidably connected to the filter box 3, and an activated carbon adsorption plate 10 for filtering sulfur dioxide fixedly installed on the inner wall of the frame 9; a gas conveying mechanism for conveying sulfur dioxide assembled between the air inlet box 2 and the filter box 3; and a circulating spray mechanism for treating sulfur dioxide installed on the air inlet box 2.

[0020] In this embodiment, during use, a certain amount of alkaline solution is injected into the filter box 3, and the inlet pipe 19 is assembled with the external sulfur dioxide discharge pipe, allowing sulfur dioxide gas to enter the inlet box 2 from the inlet pipe 19. At this time, the circulating spray mechanism installed on the inlet box 2 starts to work, performing preliminary treatment on the sulfur dioxide gas entering the inlet box 2, so that some of the sulfur dioxide gas can dissolve in water. This circulating spray mechanism can also achieve water recycling, effectively avoiding water waste. Then, the gas conveying mechanism installed between the inlet box 2 and the filter box 3 transports the pre-treated sulfur dioxide gas to the filter box 3. When the sulfur dioxide gas enters the filter box 3, the activated carbon adsorption plate 10 adsorbs and filters the sulfur dioxide, achieving... The device purifies sulfur dioxide, and also reacts with alkaline solutions to further purify it. The purified gas is then discharged from the device, making it convenient to use. After use, if the activated carbon adsorption plate 10 needs replacement, the electric slide rail 5 is activated to move the support block 6 upwards. The support block 6 then moves the support plate 7 upwards, which in turn moves the frame 9 onto the filter box 3. The frame 9 then moves the activated carbon adsorption plate 10 upwards. Once both the frame 9 and the activated carbon adsorption plate 10 have moved out of the top of the filter box 3, simply remove the bolts 8 to remove them from the support plate 7. Then, the new frame 9 and activated carbon adsorption plate 10 can be installed in the reverse manner, making replacement convenient.

[0021] In a further preferred embodiment of the present invention, the gas delivery mechanism includes: a fan 11 fixedly installed on one side of the air inlet box 2, an air extraction pipe 12 fixedly installed on the air extraction end of the fan 11, one end of the air extraction pipe 12 extending into the interior of the air inlet box 2; and an air delivery pipe 21 fixedly installed on the exhaust end of the fan 11, one end of the air delivery pipe 21 extending into the interior of the filter box 3.

[0022] In this embodiment, when the gas delivery mechanism is in use, the fan 11 is started. The fan 11 will extract the sulfur dioxide-containing gas that has been preliminarily treated by the circulating spray mechanism in the air inlet box 2 through the air extraction pipe 12 and the air delivery pipe 21 and send it into the filter box 3, so that the gas can enter the filter box 3 and be further filtered and purified by the activated carbon adsorption plate 10.

[0023] In a further preferred embodiment of this utility model, the circulating spraying mechanism includes: a hollow plate 13 fixedly installed on the inner wall of the top of the air inlet box 2, with a spray head provided at the bottom of the hollow plate 13; a partition 14 fixedly installed on the inner wall of the air inlet box 2, with a bottle body 15 threadedly installed on the partition 14, an activated carbon adsorption layer 16 provided inside the bottle body 15, and a liquid outlet hole opened at the bottom of the bottle body 15; and a water pump 17 fixedly installed on the inner wall of the bottom of the air inlet box 2, with a connecting pipe 18 fixedly installed on the discharge end of the water pump 17, one end of the connecting pipe 18 extending above the partition 14 and fixedly connected to one side of the hollow plate 13, and the connecting pipe 18 communicating with the interior of the hollow plate 13.

[0024] In this embodiment, when the circulating spraying mechanism is in use, the sulfur dioxide-containing gas enters the air inlet box 2 through the air inlet pipe 19. Then, the water pump 17 is started, and the water pump 17 will transport the water in the air inlet box 2 to the hollow plate 13 through the connecting pipe 18. The water is then sprayed out from the spray head set at the bottom of the hollow plate 13 to spray the sulfur dioxide-containing gas entering the air inlet box 2, so that some of the sulfur dioxide in the gas dissolves in the water. The sprayed water will fall on the top of the partition plate 14 and then enter the bottle body 15, so that the activated carbon adsorption layer 16 can adsorb and purify the water flowing through the bottle body 15. The purified water flows out from the liquid outlet hole opened at the bottom of the bottle body 15 to the bottom of the air inlet box 2, so that the water pump 17 will draw out the purified water again and transport it to the hollow plate 13 through the connecting pipe 18 for circulating spraying. This achieves continuous treatment of sulfur dioxide gas and water recycling, which can greatly save water costs.

[0025] In a further preferred embodiment of the present invention, a through pipe 20 is fixedly installed on the air intake box 2, one end of the through pipe 20 extends into the interior of the filter box 3, and a solenoid valve is provided on the through pipe 20.

[0026] In this embodiment, by using the pipe 20 and the solenoid valve together, the water in the air intake box 2 can be discharged into the filter box 3 when needed, so that the water mixes with the alkaline solution at the bottom of the filter box 3 and reacts.

[0027] In a further preferred embodiment of the present invention, an exhaust pipe 22 and a drain pipe are fixedly installed on the filter box 3, the drain pipe is located below the exhaust pipe 22, and a valve is provided on the drain pipe.

[0028] In this embodiment, the purified sulfur dioxide gas can be discharged to the outside of the device through the exhaust pipe 22, and the liquid in the filter box 3 can be discharged by opening the valve on the liquid draining pipe.

[0029] In a further preferred embodiment of this utility model, an addition tube is fixedly installed on the top of the filter box 3, and a cover is threaded onto the addition tube.

[0030] In this embodiment, the addition tube allows for easy injection of an alkaline solution for purifying sulfur dioxide into the filter box 3, and the addition tube can be sealed with a cover.

[0031] In a further preferred embodiment of the present invention, an opening for taking out and putting in air is provided on one side of the air intake box 2, and a sealing door is provided on the opening for taking out and putting in air.

[0032] In this embodiment, the bottle 15 can be easily removed by using the pick-up and drop-out port and the sealing door together. When removing it, first open the sealing door from the pick-up and drop-out port, and then manually rotate the bottle 15 to remove it from the partition 14. After removal, the bottle 15 can be taken out from the pick-up and drop-out port so that the activated carbon adsorption layer 16 inside can be replaced.

[0033] In summary, compared with related technologies, this solution, through the use of the intake pipe 19, allows sulfur dioxide gas to enter the intake box 2. The circulating spray mechanism provides preliminary treatment of the sulfur dioxide gas entering the intake box 2, dissolving some of the sulfur dioxide in the water. Furthermore, the water used for spraying can be recycled, effectively avoiding water waste and reducing water costs in long-term use. The gas delivery mechanism transports the pre-treated sulfur dioxide gas to the filter box 3. Once the sulfur dioxide gas enters the filter box 3, the circulating spray mechanism further enhances its performance. The activated carbon adsorption plate 10 adsorbs and filters sulfur dioxide, thus purifying it. Simultaneously, the sulfur dioxide reacts with the alkaline solution at the bottom of the filter box 3, further purifying it. The purified gas is then discharged from the exhaust pipe 22. The electric slide rail 5 moves the support block 6, support plate 7, frame 9, and activated carbon adsorption plate 10 upwards. Once the frame 9 and activated carbon adsorption plate 10 have moved from the top of the filter box 3, the frame 9 and activated carbon adsorption plate 10 can be removed from the support plate 7 by removing the bolts 8, allowing for the replacement of the activated carbon adsorption plate 10.
