Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a sulfur-containing waste gas purification and absorption device. Background Art

[0002] Sulfur-containing waste gas refers to waste gas containing sulfur compounds such as sulfur dioxide (SO2) and hydrogen sulfide (H2S). If these waste gases are directly discharged into the atmosphere, they will cause serious harm to the environment and human health, so they need to be purified;

[0003] Using activated carbon to treat sulfur-containing waste gas is a common method. During the treatment process, the sulfur-containing waste gas passes through the activated carbon bed, and the sulfur compounds are adsorbed on the surface and pores of the activated carbon, thereby achieving the purification of the waste gas. However, the use of activated carbon to treat sulfur-containing waste gas also has some limitations. For example, the adsorption capacity of activated carbon is limited. After a period of use, it will gradually become saturated and need to be regenerated or replaced, which increases the treatment cost and operational complexity. When replacing it, the remaining sulfur-containing waste gas is prone to leakage. At the same time, the part of the activated carbon close to the sulfur-containing waste gas absorbs saturation faster, resulting in a higher frequency of replacement of the activated carbon, which is not conducive to the purification of the sulfur-containing waste gas. Utility Model Content

A mounting hole 3 matching the partition 311 is provided on the top of the outer box body 1. A connecting pipe 32 is connected to the top of the mounting block 31. A connecting hole 321 communicating with the connecting pipe 32 is provided on the top of the outer box body 1. The top of the connecting pipe 32 is connected to the regulating box 33. A rotating rod 35 is rotatably connected to the center of the regulating box 33. A separation plate 352 corresponding to the connecting pipe 32 is fixedly connected to the outer wall of the rotating rod 35. Two exhaust holes 36 located on both sides of the mounting block 31 are provided on the outer wall of the mounting block 31. An air inlet pipe 34 is fixedly connected to the top of the regulating box 33.

[0018] In this embodiment: the outer box body 1 is a carrier of the carrying device, and several storage boxes 2 can be installed through the outer box body 1, so that when the activated carbon 23 is added to the storage box 2, when the sulfur-containing waste gas flows through the activated carbon 23 placed in the storage box 2, the sulfur gas in the sulfur-containing waste gas can be absorbed. The inner sliding hole 12 opened on the top of the outer box body 1 can be used to install the storage box 2, so that the storage box 2 can be opened through the inner sliding hole 12. The storage box 2 can be installed in the outer box body 1, and the activated carbon 23 in the multiple groups of storage boxes 2 can continuously filter the sulfur-containing waste gas, so that the sulfur gas in the sulfur-containing waste gas can be adsorbed by the activated carbon 23. When it is necessary to adsorb the activated carbon 23 in the storage box 2, the two sides of the position where the inner sliding hole 12 is opened are opened. The outer chute 13 is connected to it, so that the side panels 21 slidably connected to the inner wall of the outer chute 13 can slide on the front and rear sides of the storage box 2, so that when it is necessary to filter the sulfur-containing exhaust gas, the side panels 21 can slide upward so that the bottom of the side panels 21 can be in the position where the outer chute 13 is opened, so that the side panels 21 can make way for the two sides of the storage box 2, so that the storage box 2 is made of filter material, so that the storage box 2 can store the activated carbon 23 while allowing the gas to contact the activated carbon 23 after passing through the storage box 2. When replacing the activated carbon 23, the side panels 21 are lowered to close the two sides of the storage box 2, thereby disconnecting the storage box 2 from the sulfur-containing exhaust gas remaining in the outer box body 1. At this time, the storage box 2 can be taken out, so that the activated carbon 23 in the storage box 2 can be filtered. When the activated carbon 23 in the storage box 2 filters the sulfur-containing exhaust gas, the sulfur-containing exhaust gas delivery pipe can be connected to the air inlet pipe 34, the air inlet pipe 34 is connected to the regulating box 33, and the two connecting pipes 32 connected at the bottom end of the regulating box 33 can be connected to the inner cavity of the outer box body 1, and the mounting block 31 can be installed on the top of the outer box body 1 so that the partition 311 can be connected to the mounting hole 3 opened on the top of the outer box body 1, so that the partition 311 is inserted into the mounting hole 3 to interrupt the inner cavity of the outer box body 1. At this time, the rotating rod 35 at the center of the inner wall of the regulating box 33 can be rotated to drive the rotating rod 35 to drive the rotating plate 351 to block and seal the connecting pipe 32 on the left, so that the sulfur-containing exhaust gas can be connected to the connecting pipe 32 on the right through the air inlet pipe 34 to the outer box body 1, so that the sulfur-containing exhaust gas can be replaced. After entering from one of the connecting pipes 32, it flows along the inner cavity of the outer box body 1, and by closing the exhaust hole 36 on the right, the exhaust hole 36 on the left can be connected to the output pipeline to transport the gas. At this time, the gas flow direction is fixed. When the activated carbon 23 closer to the right connecting pipe 32 comes into contact with the sulfur-containing waste gas, it absorbs more sulfur gas, while the activated carbon 23 closer to the exhaust hole 36 for exhaust absorbs relatively less sulfur gas. At this time, the connection between the air inlet pipe 34 and different connecting pipes 32 can be adjusted by rotating the rotating rod 35, and then the output pipeline is connected to another exhaust hole 36, and the original exhaust hole 36 is closed, so that the device can make the sulfur-containing waste gas flow in the direction inside the outer box body 1, thereby increasing the absorption rate of the activated carbon 23 in the outer box body 1 to the sulfur-containing waste gas.

[0019] Several inner sliding holes 12 are opened at equidistant positions, and the storage box 2, the side panel 21 and the two ends of the mounting block 31 are respectively fitted with the inner wall of the outer box body 1 and the outer wall of the center column 11; the inner sliding holes 12 are opened at equidistant positions, so that the sulfur-containing exhaust gas in the inner cavity of the outer box body 1 can be filtered in sequence by the activated carbon 23 in the storage box 2 installed in the inner sliding holes 12 when it circulates, and the storage box 2 and the side panel 21 are fitted with the inner sliding holes 12 and the outer wall of the outer chute 13 to prevent the leakage of sulfur-containing exhaust gas.

[0020] The top of the storage box 2 is fixedly connected to an inner fixing block 22, and the top of the side panel 21 is fixedly connected to an outer fixing block 221 corresponding to the inner fixing block 22. The outer fixing blocks 221 are connected by an insertion rod 222, and the top of the inner fixing block 22 is fixedly connected to a pull block 24; the inner fixing block 22 fixedly connected to the top of the storage box 2 can correspond to the outer fixing block 221, so that when the storage box 2 and the inner fixing block 22 need to be taken out together for regular cleaning, they can be connected by the insertion rod 222 and taken out together. The pull block 24 is used to facilitate the pulling out of the storage box 2 and the side panel 21.

[0021] The side panels 21 and the storage box 2 fit together with the inner sliding hole 12 and the inner walls of the outer sliding groove 13, and the height of the storage box 2 and the side panels 21 corresponds to the height of the outer box body 1; the side panels 21 and the storage box 2 fit together with the inner sliding hole 12 and the inner walls of the outer sliding groove 13, so that when the storage box 2 and the side panels 21 are in the outer box body 1, their top positions are in the inner sliding hole 12 and the outer sliding groove 13, ensuring leakage of sulfur-containing exhaust gas.

[0022] Two rotating plates 351 corresponding to the connecting pipe 32 are fixedly connected to the top of the rotating rod 35; the rotating plate 351 fixedly connected to the top of the rotating rod 35 can facilitate the rotation of the rotating rod 35, and its position corresponds to the connecting pipe 32, so that the staff can adjust the position of the separation plate 352 when the rotating rod 35 rotates by corresponding the rotating plate 351 to the connecting pipe 32.

[0023] The working principle and use process of the present invention are as follows: when filtering the sulfur gas in the sulfur-containing waste gas, the sulfur-containing waste gas is connected to the outer box body 1 through the air inlet pipe 34 and the connecting pipe 32 on the right side, so that the sulfur-containing waste gas can enter from one of the connecting pipes 32 and flow along the inner cavity of the outer box body 1. The activated carbon 23 placed in the storage box 2 in the outer box body 1 adsorbs the sulfur gas. By closing the exhaust hole 36 on the right side, the exhaust hole 36 on the left side can be connected to the output pipeline to transport the gas. At this time, the gas flow direction is fixed, and the activated carbon 23 closer to the right connecting pipe 32 is in contact with the sulfur-containing waste gas. When touched, more sulfur gas is absorbed, while the activated carbon 23 near the exhaust hole 36 for exhaust absorbs relatively less. At this time, the connection between the air inlet pipe 34 and different connecting pipes 32 can be adjusted by rotating the rotating rod 35, and then the output pipe is connected to another exhaust hole 36, and the original exhaust hole 36 is closed, so that the device can make the sulfur-containing exhaust gas flow in the outer box body 1, increase the absorption rate of the sulfur-containing exhaust gas by the activated carbon 23 in the outer box body 1, and at the same time, the side plate 21 can block the two sides of the storage box 2, so that the storage box 2 can avoid leakage of sulfur-containing exhaust gas in the outer box body 1, and replace the activated carbon 23 placed in the storage box 2.
