Description
Technical Field
[0001] This invention belongs to the field of waste gas treatment device application technology, specifically a high-concentration acid mist purification tower for industrial waste gas. Background Technology
[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via various pathways; some cause direct harm, while others have a cumulative effect, further jeopardizing human health. Different substances have different effects. Acid mist purification towers, also known as acid gas purification towers, acid mist absorption towers, and waste gas purification towers, are used to remove harmful gases from waste gases. They are characterized by wide applicability, high purification efficiency, low equipment resistance, and small footprint.
[0003] Existing acid mist purification towers typically introduce acid mist into a purification tank, where it reacts with an alkaline solution. However, this method results in a low reaction rate due to the small contact area between the acid mist and the alkaline solution, ultimately leading to poor purification performance. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies and solve existing problems, this invention proposes a high-concentration acid mist purification tower for industrial waste gas.
[0005] The technical solution adopted by this invention to solve its technical problem is as follows: An industrial waste gas high-concentration acid mist purification tower, comprising a base, a purification tank, an end cap, and a stirring mechanism; the purification tank is disposed on top of the base; the end cap is disposed on top of the purification tank; the stirring mechanism is disposed inside the purification tank; the stirring mechanism includes an inlet pipe, a stirring rod, blades, a collar, a through hole, a straight rod, and an outlet pipe; the inlet pipe penetrates through the side wall of the purification tank, and one end of the inlet pipe communicates with the inside of the purification tank; the stirring rod is rotatably connected to the bottom of the end cap; the collar is fixedly connected to the outer side wall of the stirring rod; the side wall of the collar is provided with a through hole; the straight rods are symmetrically arranged on the side wall of the stirring rod; the outlet pipe… The agitator is arranged on the side wall of the straight rod. During operation, directly discharging acid mist into the purification tank results in low purification efficiency. Therefore, it is necessary to thoroughly mix the acid mist with the alkaline solution. This requires a stirring mechanism. First, the acid mist is discharged into the purification tank through the inlet pipe. Due to the high flow velocity of the acid mist, it blows onto the blades, causing the collar to drive the stirring rod to rotate. The straight rod also rotates with the stirring rod. At the same time, this high-velocity acid mist flows into the through hole, then into the cavity inside the stirring rod and the straight rod, and finally flows out through the outlet pipe. This achieves full contact between the acid mist and the alkaline solution, thereby accelerating the reaction between the acid mist and the alkaline solution and greatly improving the overall performance of the device.
[0006] Preferably, the stirring rod is hollow inside; the straight rod is hollow inside; the stirring rod and the straight rod are connected inside; and a waterproof and breathable membrane is provided at the end of the vent pipe. During operation, the acid mist flowing into the purification tank will flow through the through hole into the cavity inside the stirring rod and the straight rod, and then flow out from the vent pipe on the side wall of the straight rod, thereby accelerating the reaction between the acid mist and the alkaline solution. The waterproof and breathable membrane can prevent the alkaline solution from flowing back into the interior of the straight rod.
[0007] Preferably, the purification tank is further provided with auxiliary components; the auxiliary components include a cam, a stacked airbag, an air guide pipe, and a rubber tube; the cam is connected to the side wall of the stirring rod; the stacked airbag is disposed on the inner wall of the purification tank; the rubber tube is disposed inside the wall of the purification tank; one end of the air guide pipe is connected to the stacked airbag, and the other end is connected to the rubber tube; during operation, when the high-speed flowing acid mist blows onto the blades, causing the stirring rod to rotate, the cam will rotate, and the cam will intermittently squeeze the stacked airbag, causing the stacked airbag to compress and deform. The gas inside the stacked airbag flows into the rubber tube through the air guide pipe, causing the rubber tube to expand and deform, thus causing the alkaline solution inside the purification tank to shake, which is beneficial for stirring the alkaline solution evenly.
[0008] Preferably, an exhaust pipe is provided on the top of the end cap; a filter mechanism is provided on the top of the end cap; the filter mechanism includes a housing, an activated carbon plate, a first rotating shaft, a first gear, a second gear, a motor, a second rotating shaft, and fan blades; the housing is fixedly connected to the top of the end cap; the activated carbon plate is rotatably connected to the side wall of the housing via the first rotating shaft; the motor is located on the outer side wall of the housing; the second rotating shaft is located at the output end of the motor; the fan blades are located at the end of the second rotating shaft; the first gear is connected to the side wall of the second rotating shaft; the second gear is located on the side wall of the first rotating shaft; during operation, due to... Acid mist contains a large amount of harmful gases. If it is directly released into the air, it will pollute the atmospheric environment. Therefore, these gases need to be filtered before being released into the air. First, these gases are discharged from the exhaust pipe. Then, the motor switch is turned on, which drives the second shaft to rotate. This causes the fan blades at the end of the second shaft to start rotating, which will accelerate the flow of gas in the exhaust pipe. At the same time, the first gear on the second shaft meshes with the first gear, causing the first shaft to start rotating. This, in turn, drives the activated carbon plate to rotate, which can filter out the harmful gases in the acid mist. Then, the gas is discharged into the atmospheric environment through the through hole.
[0009] Preferably, the first gear and the second gear are in a meshing state; and the top of the housing is provided with exhaust holes.
[0010] Preferably, the top of the end cap is provided with a liquid inlet; the bottom of the base is provided with a support column; and the top of the base is also provided with a liquid outlet.
[0011] The beneficial effects of this invention are as follows:
[0012] 1. The high-concentration acid mist purification tower for industrial waste gas described in this invention is equipped with a stirring mechanism. High-speed flowing acid mist flows into the purification tank through the air inlet pipe, which will blow the blades, eventually causing the straight rod to rotate along with the stirring rod. At the same time, the acid mist will also flow into the through hole and finally flow out through the air outlet pipe, achieving full contact between the acid mist and the alkaline solution, thereby accelerating the reaction between the acid mist and the alkaline solution and greatly improving the overall performance of the device.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 6As shown, the present invention discloses a high-concentration acid mist purification tower for industrial waste gas, comprising a base 1, a purification tank 2, an end cap 3, and a stirring mechanism 4; the purification tank 2 is disposed on top of the base 1; the end cap 3 is disposed on top of the purification tank 2; the stirring mechanism 4 is disposed inside the purification tank 2; the stirring mechanism 4 includes an inlet pipe 41, a stirring rod 42, blades 43, a collar 44, a through hole 45, a straight rod 46, and an outlet pipe 47; the inlet pipe 41 penetrates the side wall of the purification tank 2, and one end of the inlet pipe 41 communicates with the interior of the purification tank 2; the stirring rod 42 is rotatably connected to the bottom of the end cap 3; the collar 44 is fixed to the outer side wall of the stirring rod 42; the side wall of the collar 44 is provided with a through hole 45; the straight rod 46 is symmetrically arranged on the side wall of the stirring rod 42; the outlet pipe 47... The pipes 47 are arranged on the side wall of the straight rod 46. During operation, since the acid mist is directly discharged into the purification tank 2, the purification efficiency of the acid mist is low. Therefore, it is necessary to fully mix the acid mist with the alkaline solution. This requires the use of the stirring mechanism 4. First, the acid mist is discharged into the purification tank 2 through the air inlet pipe 41. Due to the high flow velocity of the acid mist, it will blow onto the blades 43, causing the collar 44 to drive the stirring rod 42 to rotate. As a result, the straight rod 46 will also rotate with the stirring rod 42. At the same time, the acid mist with high flow velocity will flow into the through hole 45, and then into the cavity inside the stirring rod 42 and the straight rod 46. Finally, it will flow out through the air outlet pipe 47, achieving full contact between the acid mist and the alkaline solution, thereby accelerating the reaction between the acid mist and the alkaline solution and greatly improving the overall performance of the device.
[0024] In one embodiment of the present invention, the interior of the stirring rod 42 is hollow; the interior of the straight rod 46 is hollow; the interiors of the stirring rod 42 and the straight rod 46 are connected; a waterproof and breathable membrane is provided at the end of the vent pipe 47; during operation, the acid mist flowing into the purification tank 2 will flow from the through hole 45 into the cavity inside the stirring rod 42 and the straight rod 46, and then flow out from the vent pipe 47 on the side wall of the straight rod 46, thereby accelerating the reaction between the acid mist and the alkaline solution; wherein the waterproof and breathable membrane can prevent the alkaline solution from flowing back into the interior of the straight rod 46.
[0025] In one embodiment of the present invention, an auxiliary component 5 is also provided inside the purification tank 2; the auxiliary component 5 includes a cam 51, a stacked airbag 52, an air guide pipe 53, and a rubber tube 54; the cam 51 is connected to the side wall of the stirring rod 42; the stacked airbag 52 is disposed on the inner wall of the purification tank 2; the rubber tube 54 is disposed inside the wall of the purification tank 2; one end of the air guide pipe 53 is connected to the stacked airbag 52, and the other end is connected to the rubber tube 54; during operation, when the high-speed flowing acid mist blows onto the blade 43, the stirring rod 42 rotates, and the cam 51 rotates, and the cam 51 intermittently squeezes the stacked airbag 52, causing the stacked airbag 52 to be compressed and deformed. The gas inside the stacked airbag 52 flows through the air guide pipe 53 into the rubber tube 54, causing the rubber tube 54 to expand and deform, thus causing the alkaline solution inside the purification tank 2 to shake, which is beneficial for stirring the alkaline solution evenly.
[0026] In one embodiment of the present invention, an exhaust pipe 31 is provided on the top of the end cap 3; a filter mechanism 6 is provided on the top of the end cap 3; the filter mechanism 6 includes a housing 61, an activated carbon plate 62, a first rotating shaft 63, a first gear 64, a second gear 65, a motor 66, a second rotating shaft 67, and fan blades 68; the housing 61 is fixedly connected to the top of the end cap 3; the activated carbon plate 62 is rotatably connected to the side wall of the housing 61 via the first rotating shaft 63; the motor 66 is located on the outer side wall of the housing 61; the second rotating shaft 67 is located at the output end of the motor 66; the fan blades 68 are located at the end of the second rotating shaft 67; the first gear 64 is connected to the side wall of the second rotating shaft 67; the second gear 65 is located on the side wall of the first rotating shaft 63; the first gear 64 and the second gear 65 are in a meshing state; the top of the housing 61 is arranged with... The exhaust port 69; the top of the end cap 3 is provided with a liquid inlet 32; the bottom of the base 1 is provided with a support column 11; the top of the base 1 is also provided with a liquid outlet 12; during operation, since the acid mist contains a large amount of harmful gases, directly releasing it into the air will pollute the atmospheric environment. Therefore, these gases need to be filtered before being released into the air. First, these gases are discharged from the exhaust pipe 31. Then, the switch of the motor 66 is turned on, causing the motor 66 to drive the second rotating shaft 67 to rotate. This causes the fan blades 68 at the end of the second rotating shaft 67 to also start rotating, which will accelerate the flow of gas in the exhaust pipe 31. At the same time, the first gear 64 on the second rotating shaft 67 meshes with the first gear 64, causing the first rotating shaft 63 to start rotating, which in turn drives the activated carbon plate 62 to rotate, which can filter out the harmful gases in the acid mist and then discharge them into the atmospheric environment from the exhaust port 69.
[0027] Working Principle: During operation, directly discharging acid mist into the purification tank 2 results in low purification efficiency. Therefore, it is necessary to thoroughly mix the acid mist with the alkaline solution. This requires the use of a stirring mechanism 4. First, the acid mist is discharged into the purification tank 2 through the air inlet pipe 41. Due to the high flow velocity of the acid mist, it blows onto the blades 43, causing the collar 44 to drive the stirring rod 42 to rotate. Consequently, the straight rod 46 also rotates along with the stirring rod 42. Simultaneously, this high-velocity acid mist flows into the through hole 45, then into the cavity inside the stirring rod 42 and the straight rod 46, and finally flows out through the air outlet pipe 47. This achieves sufficient contact between the acid mist and the alkaline solution, thereby accelerating the reaction between the acid mist and the alkaline solution and greatly improving the overall effectiveness of the device. When the high-speed flowing acid mist blows onto the blades 43, causing the stirring rod 42 to rotate, the cam 51 will rotate. The cam 51 will then intermittently squeeze the stacked airbag 52, causing the stacked airbag to rotate. The airbag 52 is compressed and deformed, and the gas inside the stacked airbag 52 flows through the air guide tube 53 into the rubber tube 54, causing the rubber tube 54 to expand and deform. This causes the alkaline solution inside the purification tank 2 to shake, which helps to stir the alkaline solution evenly. Since the acid mist contains a large amount of harmful gases, directly releasing it into the air will pollute the atmospheric environment. Therefore, these gases need to be filtered before being released into the air. First, these gases are discharged from the exhaust pipe 31. Then, the switch of the motor 66 is turned on, causing the motor 66 to drive the second rotating shaft 67 to rotate. Then, the fan blades 68 at the end of the second rotating shaft also start to rotate, which will accelerate the flow of gas in the exhaust pipe 31. At the same time, the first gear 64 on the second rotating shaft 67 will mesh with the first gear 64, causing the first rotating shaft 63 to start rotating, which in turn drives the activated carbon plate 62 to rotate, which can filter out the harmful gases in the acid mist and then discharge it into the atmospheric environment through the exhaust port 69.
