Description

Technical Field

[0001] This utility model relates to the field of liquid polyferric sulfate production technology, and in particular to a tail gas absorption tower for liquid polyferric sulfate production. Background Technology

[0002] Liquid polyferric sulfate (PFS) is a chemical substance, a reddish-brown liquid without precipitation. It is widely used in the purification of drinking water, industrial water, various industrial wastewater, municipal sewage, and sludge dewatering. The preparation of PFS mainly involves direct oxidation and catalytic oxidation. Most PFS are prepared using the direct oxidation method, which has a simpler process route and can reduce equipment investment and production steps, thus lowering equipment costs in industrial production. However, this process relies on oxidants such as inorganic oxidants like H2O2, KClO3, and HNO3. The catalytic oxidation method generally uses a catalyst to oxidize PFS using oxygen or air.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4As shown, this embodiment proposes a tail gas absorption tower for the production of liquid polyferric sulfate, including a frame assembly 1 and a suction and compression component 2. The suction and compression component 2 is bolted to the inner side of the frame assembly 1, and a through-sleeved suction and dispersion component 3 is provided on the inner side of the suction and compression component 2.

[0021] The intake compression component 2 includes a cooling chamber 201, an airlock chamber 202, an air pump motor 203, an air pump body 204, a connecting pipe 205, an intake nozzle 206, a top cover 207, a hydraulic cylinder 208, and a pressure plate 209. The cooling chamber 201 is sleeved and connected to the inner side of the frame assembly 1. The airlock chamber 202 is provided on the upper outer side of the cooling chamber 201, and the air pump body 204 connected to the output end of the air pump motor 203 is provided on the outer side of the airlock chamber 202. The intake nozzle 206 is sleeved and connected to the air pump body 204 through the connecting pipe 205. The top of the cooling chamber 201 is provided with a bolted top cover 207, and the hydraulic cylinder 208 is provided around the top of the top cover 207. The output end of the hydraulic cylinder 208 is provided with a pressure plate 209.

[0022] The central axis of the air compressor plate 209 and the cooling chamber 201 are on the same straight line, and the air intake 206 has a porous structure.

[0023] In this embodiment, the airlock chamber 202 is then opened, and the air pump motor 203 is started to output power, so that the air pump motor 203 outputs power to drive the air pump body 204 to run, so that the connecting pipe 205 cooperates with the air intake nozzle 206 to extract the exhaust gas. After extraction, the exhaust gas is input into the cooling chamber 201 through the pipeline, and the hydraulic cylinder 208 on the top cover 207 outputs power to drive the output end to run, so that the air pressure plate 209 pushes the gas.

[0024] The frame assembly 1 includes a base pad 101, a first base plate 102, a bolted housing 103, a side frame 104, a fixing platform 105, and a fan 106. The first base plate 102 is bolted on one end of the base pad 101, and the bolted housing 103 is provided on the inner side of the first base plate 102.

The fan 106 is bolted on the inner sides of both ends of the fixing platform 105.

[0025] In this embodiment, when in use, the various components are assembled by using the base pad 101 in conjunction with the first substrate 102 and the second substrate 401, and the power output of the fan 106 on both sides of the fixed platform 105 drives the output end to run, which blows air onto the external connecting pipe 304 and the external fin plate 305 to achieve a continuous heat dissipation effect.

[0026] The absorption assembly 3 includes a through pipe 301, an inner connecting pipe 302, an inner fin 303, an outer connecting pipe 304, and an outer fin 305.

The inner connecting pipe 302 is provided on the inner side of the through pipe 301, and the inner connecting pipe 302 is sleeved and connected to the inner fin 303. The outer connecting pipe 304 is provided on the outer side of the through pipe 301, and the outer connecting pipe 304 is sleeved and connected to the outer fin 305.

[0027] In this embodiment, when the gas is inside the cooling chamber 201, the inner connecting pipe 302 and the inner fin plate 303 pre-absorb the heat of the gas, and dissipate it through the through pipe 301, the outer connecting pipe 304, and the outer fin plate 305.

[0028] The directional purification component 4 includes a second base plate 401, a lifting frame 402, a top base shell 403, a directional pipe 404, a side pipe 405, a lower valve block 406, a purification chamber 407, a catalyst block 408, an activated carbon group 409, a separator plate 4010, a filter element block 4011, an upper valve block 4012, and an exhaust nozzle 4013. The second base plate 401 is bolted to the top of the other end of the base pad 101. The lifting frame 402 is provided on the side of the second base plate 401, and the top base shell 403 is provided at the top of the lifting frame 402. The directional pipe 404 is provided on the inner bottom side of the second base plate 401, and the side pipe 405 is provided on one side of the directional pipe 404. The exhaust nozzle 4013 is provided at the top of the top base shell 403.

[0029] In this embodiment, the gas is then input through the side pipe 405 to the branch pipe 404, and after being output from the branch pipe 404, it is input to the lower valve block 406 above the periphery of the second substrate 401. After the lower valve block 406 is opened, the gas is input into the purification chamber 407.

[0030] A lower valve block 406 is provided at the output end of the branch pipe 404, and a purification chamber 407 is provided above the lower valve block 406. A catalyst block 408 is provided on the inner bottom side of the purification chamber 407, and an activated carbon group 409 is provided above the catalyst block 408. An isolation plate 4010 is provided above the activated carbon group 409, and a filter element block 4011 is provided above the isolation plate 4010. An upper valve block 4012 is provided at the top of the purification chamber 407.

[0031] In this embodiment, after the gas is input into the purification chamber 407, the catalyst block 408, in sequence, cooperates with the activated carbon group 409 and the isolation plate 4010 to react and adsorb through the filter core block 4011, so that the gas achieves the effect of purification and discharge. After the upper valve block 4012 is opened, the gas is finally discharged from the equipment through the exhaust port 4013, so as to complete the absorption effect.

[0032] The working principle of the tail gas absorption tower for liquid polyferric sulfate production is as follows: During use, the various components are assembled using the base pad 101 in conjunction with the first substrate 102 and the second substrate 401. Power is output from the fan 106 on both sides of the fixed platform 105 to drive the output end, which then blows air onto the external connecting pipe 304 and the external fins 305, achieving continuous heat dissipation. Next, the airlock chamber 202 is opened, and the air pump motor 203 is started, driving the air pump body 204. This allows the connecting pipe 205, in conjunction with the suction nozzle 206, to extract the tail gas. After extraction, the tail gas is piped into the cooling chamber 201. At appropriate times, the hydraulic cylinder 208 on the top cover 207 outputs power to drive the output end, causing the pressure plate 209 to pressurize the gas. As the gas flows through the cooling chamber 201, the internal connecting pipe 302 and the internal fin 303 pre-absorb the heat of the gas, and dissipate it through the through pipe 301, the external connecting pipe 304, and the external fin 305. Then, the gas is input through the side pipe 405 to the branch pipe 404, and after the output of the branch pipe 404, it is input to the lower valve block 406 above the second substrate 401. After the lower valve block 406 is opened, the gas is input into the purification chamber 407. After the gas is input into the purification chamber 407, the catalyst block 408, in sequence with the activated carbon group 409 and the isolation plate 4010, reacts and is filtered by the filter core block 4011 to achieve the effect of purified gas discharge. After the upper valve block 4012 is opened, the gas is finally discharged from the equipment through the exhaust port 4013 to complete the absorption effect.
