Description

Technical Field

[0001] The invention relates to the technical field of waste gas purification, and in particular to a purification device for treating waste gas from the production and processing of sulphur black. Background Art

[0002] At present, the tail gas in the production process of sulfide black contains hydrogen sulfide and ammonia. Hydrogen sulfide is a toxic gas with the smell of rotten eggs. It mainly comes from the preparation of sodium polysulfide and the sulfidation reaction process. In the preparation process of sodium polysulfide, the reaction of sodium sulfide and sulfur may produce a side reaction to release hydrogen sulfide. In the sulfidation reaction, the reaction of sulfur-containing compounds will also produce hydrogen sulfide. Ammonia mainly comes from the decomposition of nitrogen-containing compounds in the hydrolysis and sulfidation reaction process. When purifying the waste gas, an alkaline solution is usually used to react with the waste gas to purify and remove the internal hydrogen sulfide; When the exhaust gas is introduced into the alkaline solution through the pipeline for reaction, due to the single gap for exhaust gas outlet when closed, the alkaline solution penetrates from the gap position, causing corrosion damage. Summary of the invention

During the process of increasing the pressure, the gap between the disc and the conical surface at the top of the inner wall of the connecting pipe is opened by moving the shaft disc upward. At the same time, driven by the shaft disc, the sliding column opens the gap between the sliding column and the bevel ring, so that the exhaust gas first passes through the gap of the disc, and then is discharged through the gap between the sliding column and the bevel ring to perform a neutralization reaction. The exhaust gas is discharged through the two gaps. At the same time, after closing, there is still gas between the two gaps, and there is air pressure in the space to prevent the alkaline solution from penetrating from the gap position when there is no gas inside during closing, causing corrosion damage.

Through the cooperation between the air guide pipe and the spring, when the exhaust gas is introduced, it is necessary to overcome the hydraulic pressure and spring deformation pressure to prevent the air pressure from decreasing, resulting in a low gas outflow speed, causing alkali solution to penetrate into the gas pipeline and cause corrosion damage. At the same time, in conjunction with the tortuosity of the air guide pipe, after a small amount of alkaline solution penetrates, it is stored at the tortuous end of the air guide pipe to avoid directly flowing into the dust removal mechanism. A rubber gasket is fixedly installed on the outside of the connecting pipe.

[0005] Preferably, the dust removal mechanism includes a fixed cylinder, the bottom of which is fixedly connected to the bottom of the inner wall of the tank body, and a conical cylinder is fixedly installed on the top of the fixed cylinder. Through the cooperation between the conical cylinder and the top plate, when the exhaust gas is introduced, the guide of the conical cylinder and the path gap change, so that the flow velocity of the exhaust gas is accelerated in the process of upward conduction, and the exhaust gas impacts the top plate and then diffuses obliquely downward to the surrounding areas, so that the gauze can comprehensively screen the exhaust gas and prevent the exhaust gas from directly impacting the surface of the gauze to cause serious blockage that is difficult to clean.

[0007] Preferably, the alkali liquid mechanism comprises an alkali liquid bin, a fixing ring is fixedly installed at the bottom of the alkali liquid bin, the alkali liquid bin is fixedly installed on the inner wall of the tank body through the fixing ring, and the bottom of the alkali liquid bin is fixedly connected to the outer side of the connecting pipe, and the top of the connecting pipe passes through the alkali liquid bin and extends to the inside thereof, an air outlet is opened at the center position of the top of the alkali liquid bin, and the air outlet of the alkali liquid bin is fixedly connected to the bottom end of the exhaust pipe, a fixing shaft is fixedly installed at the center position of the bottom of the inner wall of the alkali liquid bin, a swivel is rotatably installed on the outer side of the fixing shaft, a fixing plate is fixedly installed on the outer side of the swivel, and an inner screw is fixedly installed on the outer side of the fixing plate A plate, an outer spiral plate is fixedly installed at one end of the outer side of the fixed plate away from the rotating ring, and a rotary impeller is rotatably installed between the outer spiral plate and the inner spiral plate. When the alkaline solution is driven by the exhaust gas to surge upward, the rotary impeller is driven to rotate. At the same time, the rotating ring is rotated according to the spiral distribution of the rotary impeller. Driven by the surging solution, the rotary impeller rotates itself and rotates along the axis of the fixed axis, thereby improving the uniformity of solution mixing and avoiding uneven alkaline substances in the solution, which leads to incomplete removal of acidic substances during neutralization reaction.

[0008] The present invention provides a purification device for treating waste gas from the production and processing of sulfur black. It has the following beneficial effects: 1. The purification equipment for treating waste gas from the production and processing of sulfur black cooperates with the disc of the shaft disc and the sliding column. In the process of increasing internal air pressure, the shaft disc moves upward to open the gap between the disc and the conical surface at the top of the inner wall of the connecting pipe. At the same time, driven by the shaft disc, the sliding column opens the gap between the sliding column and the bevel ring, so that the waste gas first passes through the gap of the disc and then is discharged through the gap between the sliding column and the bevel ring to perform a neutralization reaction. The waste gas is discharged through the two gaps. At the same time, after closing, there is still gas between the two gaps, and there is air pressure in the space, which prevents the alkaline solution from penetrating from the gap position when there is no gas inside during closing, causing corrosion damage.

[0009] 2. The purification equipment used for waste gas treatment in the production and processing of sulphur black, through the cooperation between the air duct and the spring, needs to overcome the hydraulic pressure and spring deformation pressure when the waste gas is introduced to prevent the air pressure from decreasing, resulting in a low gas outflow speed, causing alkaline solution to penetrate into the gas pipeline and cause corrosion damage. At the same time, in conjunction with the twists and turns of the air duct, after a small amount of alkaline solution penetrates, it is stored at the tortuous end of the air duct to avoid directly flowing into the dust removal mechanism.

[0010] 3. The purification equipment used for waste gas treatment in the production and processing of sulfur black, through the cooperation of the conical cylinder and the top plate, when the waste gas is introduced, the guidance of the conical cylinder and the path gap change, so that the flow rate of the waste gas in the process of upward conduction is accelerated, and the waste gas impacts the top plate and diffuses obliquely downward in all directions, so that the gauze can comprehensively screen out the waste gas, and at the same time prevent the waste gas from directly impacting the surface of the gauze, causing serious blockage that is difficult to clean.

[0011] 4. The purification equipment used for waste gas treatment in the production and processing of sulfur black, through the cooperation of the inclined cylinder and the gauze, allows the waste gas to flow downward under the restriction of the inner wall of the inclined cylinder. At the same time, the distance between the inclined cylinder and the gauze gradually decreases from top to bottom, which accelerates the flow speed. In conjunction with the annular protrusion, the waste gas fluctuates when flowing, impacts the gauze from inside and outside, and offsets the waste gas flowing outward, thereby cleaning the gauze and reducing the impact force of particles when impacting the gauze.

[0012] 5. The purification equipment for treating waste gas from the production and processing of sulphur black drives the impeller to rotate when the alkaline solution is driven upward by the exhaust gas. At the same time, the rotating ring rotates according to the spiral distribution of the impeller. Driven by the surging solution, the impeller rotates itself and along the axis of the fixed axis, thereby improving the uniformity of solution mixing and avoiding uneven alkaline substances in the solution, which leads to incomplete removal of acidic substances during the neutralization reaction.

[0016] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a purification device for treating waste gas from the production and processing of sulphur black, comprising: The tank body 1 provides a place for exhaust gas purification, and the top and bottom of the tank body 1 are respectively equipped with an exhaust pipe 5 and an intake pipe 6; A dust removal mechanism 3, which is used to remove smoke particles in the exhaust gas, and the dust removal mechanism 3 is installed at the bottom of the inner wall of the tank body 1, and the bottom of the dust removal mechanism 3 is connected to the air inlet pipe 6; An alkali liquid mechanism 4, which is used to neutralize the exhaust gas with alkali liquid, and the alkali liquid mechanism 4 is installed on the top of the inner wall of the tank body 1, and the top of the alkali liquid mechanism 4 is connected to the bottom end of the exhaust pipe 5; An air guide mechanism 2, which is used to guide the exhaust gas from which smoke particles are removed into the alkali solution, and the air guide mechanism 2 is fixedly installed between the dust removal mechanism 3 and the alkali solution mechanism 4; Among them, the air guide mechanism 2 includes a sealing ring cover 201, the bottom of the sealing ring cover 201 is fixedly connected to the top of the dust removal mechanism 3, and the outer side of the sealing ring cover 201 is tightly fitted with the inner wall of the tank body 1, and an air guide pipe 202 is fixedly installed on the top of the sealing ring cover 201. The air guide pipe 202 is evenly installed along the center position of the sealing ring cover 201, and a connecting pipe 203 is fixedly installed at one end of the air guide pipe 202 away from the sealing ring cover 201, and a bevel ring 206 is fixedly installed on the top of the connecting pipe 203. In the process of continuous accumulation of exhaust gas, the air pressure gradually increases, and the disc of the shaft disc 207 is pushed upward by the air pressure, so that the shaft disc 207 drives the spring 209 to compress and deform through the connecting rod 208, and at the same time When the shaft disc 207, the connecting rod 208 and the sliding column 205 slide upward together, and a gap appears between the shaft disc 207 and the conical surface of the connecting pipe 203, a gap of the same size is opened between the sliding column 205 and the bevel ring 206 at the same time, so that the exhaust gas is conducted upward through the gap between the shaft disc 207 and the connecting pipe 203, and then discharged through the gap between the sliding column 205 and the bevel ring 206, and enters the alkali solution mechanism 4 for neutralization reaction. The inner wall of the bevel ring 206 is a conical bevel, and the sliding column 205 is slidably installed on the inner wall of the bevel ring 206. The shaft disc 207 is fixedly installed at the bottom of the sliding column 205. The shaft disc 207 is composed of a shaft block and a disc, and the top of the inner wall of the connecting pipe 203 is a conical bevel.

[0017] A connecting rod 208 is fixedly installed at the bottom of the shaft disk 207, and a groove disk 210 is fixedly installed on the inner wall of the connecting pipe 203. The inner wall of the groove disk 210 is slidably adapted to the outer side of the connecting rod 208. A spring 209 is fixedly installed at the bottom of the groove disk 210. After the exhaust gas passes through the dust removal mechanism 3 to remove smoke particles, it gathers at the bottom of the sealing ring cover 201. Through the connection between the sealing ring cover 201 and the air guide pipe 202, the air guide pipe 202 guides the exhaust gas into the connecting pipe 203. The bottom end of the spring 209 is fixedly connected to the bottom of the outer side of the connecting rod 208. The air guide pipe 202 is a zigzag circular tube, and a rubber gasket 204 is fixedly installed on the outer side of the connecting pipe 203.

[0018] The second embodiment is based on the first embodiment. Figure 6 to Figure 7As shown, the dust removal mechanism 3 includes a fixed cylinder 35, the bottom of which is fixedly connected to the bottom of the inner wall of the tank body 1, and a conical cylinder 37 is fixedly installed on the top of the fixed cylinder 35. The inner diameter of the conical cylinder 37 gradually increases from top to bottom, and a turntable 36 is fixedly installed on the inner wall of the fixed cylinder 35. The exhaust gas is introduced through the air inlet pipe 6. Through the cooperation of the fixed cylinder 35 and the conical cylinder 37, the exhaust gas introduced into the tank body 1 first enters the interior of the fixed cylinder 35 and the conical cylinder 37. Through the guidance of the conical cylinder 37 and the change of the inner diameter, the exhaust gas in the conical cylinder 37 quickly surges upward and impacts the top of the top plate 34. A support frame 39 is fixedly installed on the top of the turntable 36, and empty grooves are evenly opened on the outer side of the support frame 39, and meshes 38 are fixedly installed at the empty grooves of the support frame 39.

[0019] A top plate 34 is fixedly installed on the top of the support frame 39, and an arc cover ring 32 is fixedly installed on the edge of the bottom of the rotating disk 36. The inner wall of the arc cover ring 32 is provided with an arc-shaped groove, and a sealing ring 31 is fixedly installed on the bottom of the arc cover ring 32. The outer side of the sealing ring 31 is tightly fitted with the inner wall of the tank body 1. The top of the top plate 34 is fixedly connected to the bottom of the sealing ring cover 201, and a bevel cylinder 33 is fixedly installed on the bottom of the top plate 34. The bevel cylinder 33 is located on the outer side of the gauze 38. Under the restriction of the top plate 34, the exhaust gas is diffused to the surroundings, and the gauze 38 is fixedly installed in the support frame 39 to screen out the smoke and dust particles in the exhaust gas, so that the exhaust gas can be removed. The exhaust gas after the smoke and dust particles are removed reaches the outside of the gauze 38, and flows downward under the restriction of the inclined cylinder 33, flows out from the gap between the bottom end of the inclined cylinder 33 and the arc cover ring 32, and surges upward from the outside of the inclined cylinder 33. At the same time, in the process of the exhaust gas flowing downward along the inner wall of the inclined cylinder 33, the gradually decreasing gap between the inclined cylinder 33 and the gauze 38 accelerates the downward flow speed. At the same time, the annular protrusion on the inner wall of the inclined cylinder 33 is used to make the flow of the exhaust gas fluctuate, impacting the gauze 38 from the outside to the inside, and the distance between the inclined cylinder 33 and the gauze 38 gradually decreases from top to bottom. The inner wall of the inclined cylinder 33 is evenly provided with annular protrusions from top to bottom.

[0020] The third embodiment is based on the first and second embodiments. Figures 8 to 9As shown, the alkali liquid mechanism 4 includes an alkali liquid tank 41, a fixing ring 42 is fixedly installed at the bottom of the alkali liquid tank 41, the alkali liquid tank 41 is fixedly installed on the inner wall of the tank body 1 through the fixing ring 42, and the bottom of the alkali liquid tank 41 is fixedly connected to the outer side of the connecting pipe 203, and the top of the connecting pipe 203 passes through the alkali liquid tank 41 and extends to the inside thereof, and an air outlet is opened at the center position of the top of the alkali liquid tank 41. Through the fixed connection between the alkali liquid tank 41 and the connecting pipe 203, when working, the corresponding alkaline solution is added to the alkali liquid tank 41, and the exhaust gas flows upward from the bottom of the inner cavity of the alkali liquid tank 41, reacts with the alkaline solution, and reacts to neutralize and purify the acidic substances in the exhaust gas, so as to avoid the acidic substances in the exhaust gas being directly discharged into the air to cause air pollution, and the air outlet of the alkali liquid tank 41 is fixedly connected to the bottom end of the exhaust pipe 5, and a fixed shaft 43 is fixedly installed at the center position of the bottom of the inner wall of the alkali liquid tank 41.

[0021] A swivel 44 is rotatably mounted on the outer side of the fixed shaft 43, a fixed plate 46 is fixedly mounted on the outer side of the swivel 44, an inner screw plate 45 is fixedly mounted on the outer side of the fixed plate 46, an outer screw plate 47 is fixedly mounted on the outer end of the fixed plate 46 away from the swivel 44, a rotary impeller 48 is rotatably mounted between the outer screw plate 47 and the inner screw plate 45, and the rotary impeller 48 is evenly mounted along the spiral shape of the outer screw plate 47 and the inner screw plate 45. In the process in which the exhaust gas reacts with the alkaline solution and drives the alkali solution in the alkali solution bin 41 to surge upward, the surging alkaline solution drives the rotary impeller 48, so that the rotary impeller 48 rotates under the drive of the surging solution, and the solution is stirred by the stirring blade. At the same time, the rotary impeller 48 is spirally distributed between the inner screw plate 45 and the outer screw plate 47 to rotate the swivel 44, and the outer side of the rotary impeller 48 is evenly provided with stirring blades.

[0022] When in use, workers connect the exhaust gas discharge pipe with the air inlet pipe 6, so that the exhaust gas enters the interior of the tank body 1 through the air inlet pipe 6, and the tail gas first enters the dust removal mechanism 3, and the smoke and dust particles in the exhaust gas are screened out by the dust removal mechanism 3, and the exhaust gas after the smoke and dust particles are removed is introduced into the alkali liquid mechanism 4 through the air guide mechanism 2. When the exhaust gas is guided by the air guide mechanism 2, the exhaust gas is evenly introduced from the bottom of the alkali liquid mechanism 4, and the acidic substances in the exhaust gas are reacted and neutralized by the alkaline solution in the alkali liquid mechanism 4.

[0023] When the dust particles in the exhaust gas are screened by the dust removal mechanism 3, the exhaust gas is introduced through the air inlet pipe 6. Through the cooperation of the fixed cylinder 35 and the conical cylinder 37, the exhaust gas introduced into the tank body 1 first enters the interior of the fixed cylinder 35 and the conical cylinder 37. Through the guidance of the conical cylinder 37 and the change of the inner diameter, the exhaust gas in the conical cylinder 37 quickly surges upward and impacts the top of the top plate 34. At the same time, under the restriction of the top plate 34, the exhaust gas diffuses to the surroundings, and passes through the gauze 38 fixedly installed in the support frame 39, so that the gauze 38 can filter the smoke particles in the exhaust gas. The smoke particles are screened out, so that the exhaust gas after the smoke particles are removed reaches the outside of the gauze 38, and flows downward under the restriction of the inclined cylinder 33, flows out from the gap between the bottom end of the inclined cylinder 33 and the arc cover ring 32, and surges upward from the outside of the inclined cylinder 33. At the same time, in the process of the exhaust gas flowing downward along the inner wall of the inclined cylinder 33, the gradually decreasing gap between the inclined cylinder 33 and the gauze 38 accelerates the downward flow speed. At the same time, the annular protrusion on the inner wall of the inclined cylinder 33 is used to make the flow of the exhaust gas fluctuate and impact the gauze 38 from the outside to the inside.

[0024] After the exhaust gas passes through the dust removal mechanism 3 to remove the smoke particles, it gathers at the bottom of the sealing ring cover 201. Through the connection between the sealing ring cover 201 and the air guide pipe 202, the air guide pipe 202 guides the exhaust gas into the connecting pipe 203. In the process of continuous accumulation of exhaust gas, the air pressure gradually increases, and the disc of the shaft disc 207 is pushed upward by the air pressure, so that the shaft disc 207 drives the spring 209 to compress and deform through the connecting rod 208. At the same time, the shaft disc 207, the connecting rod 208 and the sliding column 205 slide upward together. When a gap appears between the shaft disc 207 and the conical surface of the connecting pipe 203, the same size gap is opened between the sliding column 205 and the bevel ring 206 at the same time, so that the exhaust gas is conducted upward from the gap between the shaft disc 207 and the connecting pipe 203, and then discharged through the gap between the sliding column 205 and the bevel ring 206, and enters the alkali solution mechanism 4 for neutralization reaction.

[0025] When waste water is introduced into the alkali liquid mechanism 4 by the air guide mechanism 2, the alkali liquid tank 41 is fixedly connected to the connecting pipe 203. During operation, the corresponding alkaline solution is added into the alkali liquid tank 41, and the waste gas flows upward from the bottom of the inner cavity of the alkali liquid tank 41 to react with the alkaline solution, and the acidic substances in the waste gas are reacted and neutralized to purify it, so as to avoid the acidic substances in the waste gas being directly discharged into the air to cause air pollution. The waste gas reacts with the alkaline solution and drives the alkali liquid in the alkali liquid tank 41 to surge upward. In the process, the surging alkaline solution drives the impeller 48, so that the impeller 48 rotates under the drive of the surging solution, and the solution is stirred by the stirring blade. At the same time, the impeller 48 is spirally distributed between the inner spiral plate 45 and the outer spiral plate 47 to rotate the rotating ring 44.
