Description

Technical Field

[0001] The invention belongs to the field of waste gas treatment devices, in particular to a polypropylene tail gas treatment device. Background Art

[0002] In the production of electronic component factories, chemical pollution, metallurgy, and thermal power plants, tail gas often contains hydrogen chloride, chlorine, and sulfur dioxide. These tail gases are directly discharged into the atmosphere, which will seriously pollute the environment. Therefore, the tail gas generated needs to be treated. The tail gas treatment mostly uses absorption towers, packed towers, and washing towers. They have a strong adsorption capacity for waste gas. The absorption tower is filled with fillers, and the absorption liquid is sprayed on the fillers to contact with the tail gas for absorption. Spraying the absorption liquid on the fillers can increase the contact area between the absorption liquid and the tail gas, thereby improving the absorption efficiency. However, after a long time, the impurities adsorbed on the surface of the filler, and the adsorption of the filler gradually deteriorates. The filler needs to be replaced regularly. The operation process is time-consuming and cumbersome. Therefore, we designed a polypropylene tail gas treatment device that can reduce the number of filler replacements. Summary of the invention

[0009] In the polypropylene tail gas treatment device as described above, a second avoidance groove is provided on the vertical pipe and the partition corresponding to the first gear.

[0010] As described above, a polypropylene tail gas treatment device, a part of the spherical surface of the packing cage is rotatably connected to another part, and a limiting mechanism for limiting the relative rotation of the spherical surface of the packing cage is provided.

A plug rod is installed in the slide groove through a spring, and one end of the plug rod is plugged into the slot.

[0012] The advantages of the present invention are: the present invention has a simple structure and an ingenious design. When the stuffing cage enters the absorption liquid accumulated at the bottom of the tank body, the stuffing cage can be cleaned by the absorption liquid when moving in the absorption liquid, thereby improving its adsorption effect, being able to meet actual needs, and being suitable for promotion. When using the present invention, after sufficient absorption liquid is introduced into the tank body through the drain pipe, the input is stopped, and then the exhaust gas is introduced into the tank body through the intake pipe. Subsequently, the exhaust gas flows upward into the stuffing cage, and the absorption liquid sprayed from the spray pipe is sprayed onto the filler in the stuffing cage. The exhaust gas contacts the absorption liquid on the filler and is absorbed and purified. The sprayed absorption liquid accumulates in the tank body and can be discharged through the drain pipe after reaching the height of the drain pipe, thereby avoiding excessive accumulation of absorption liquid. The purified exhaust gas flows to the top of the tank body and is discharged from the exhaust pipe to enter the next process. Since the exhaust gas first contacts the filler near the intake pipe, the exhaust gas is discharged from the exhaust pipe. The packing cage on the lower side is more polluted, while the packing cage on the upper side is less polluted. When the packing in the packing cage needs to be cleaned, the first motor is controlled to operate, so that the first motor drives the rotating shaft to rotate counterclockwise, and then drives the sprocket to rotate counterclockwise, so that the chain drives the packing cage to revolve counterclockwise, so that the packing cage on the upper left side of the tank body moves downward, and the packing cage on the lower left side enters the absorption liquid. When the packing cage moves in the absorption liquid, the absorption liquid flushes the packing in the packing cage, thereby restoring part of its absorption capacity, thereby reducing the replacement cycle of the packing.

The stuffing in this embodiment is a polyhedral hollow sphere, and the two parts of the partition 7 are respectively provided with a through groove that allows the stuffing cage 14 to pass through. The present invention has a simple structure and an ingenious design. When the filler cage 14 enters the absorption liquid accumulated at the bottom of the tank body 1, the filler cage 14 can be cleaned by the absorption liquid while moving in the absorption liquid, thereby improving its adsorption effect, meeting actual needs, and being suitable for promotion.When using the present invention, firstly, the end of the spray pipe 8 located outside the tank body 1 is connected to the high-pressure water source, and clean water is pumped into the spray pipe 8 by a high-pressure pump, and sprayed out through the nozzle on the spray pipe 8, and the sprayed clean water is sprayed onto the stuffing cage 14 and the stuffing in the stuffing cage 14. In this embodiment, the clean water is absorption liquid, and the absorption liquid is collected at the bottom of the tank body 1 until the liquid level of the absorption liquid submerges the lower end of the vertical plate 9 to prevent the exhaust gas from entering the right side of the vertical plate 9, and then the exhaust gas is passed into the tank body 1 through the air intake pipe 2, and then the exhaust gas flows upward into the stuffing cage 14, and the absorption liquid sprayed from the spray pipe 8 is sprayed onto the stuffing in the stuffing cage 14, and the exhaust gas contacts with the absorption liquid on the stuffing to be absorbed and purified, and the sprayed absorption liquid accumulates in the tank body 1, and can be discharged through the drainage pipe 3 after reaching the height of the drainage pipe 3, avoiding Too much absorption liquid accumulates, and the purified exhaust gas flows to the top of the tank body 1 and is discharged from the exhaust pipe 6 to enter the next process. Since the exhaust gas first contacts the stuffing cage 14 close to the intake pipe 2, the stuffing cage 14 on the lower side is highly polluted, and the stuffing cage 14 on the upper side is less polluted. When it is necessary to clean the stuffing in the stuffing cage 14, the first motor 11 is controlled to operate, so that the first motor 11 drives the rotating shaft 10 to rotate counterclockwise, and then drives the sprocket 12 to rotate counterclockwise, so that the chain 13 drives the stuffing cage 14 to revolve counterclockwise, so that the stuffing cage 14 on the upper left side of the tank body 1 moves downward, and the stuffing cage 14 on the lower left side enters the absorption liquid. When the stuffing cage 14 moves in the absorption liquid, the absorption liquid flushes the stuffing in the stuffing cage 14, thereby restoring part of its absorption capacity, thereby reducing the replacement cycle of the stuffing.

[0018] Specifically, if Figure 1 , Figure 2 As shown, the vertical pipe 20 is fixedly installed on the partition plate 7 corresponding to the through groove in this embodiment, and the vertical pipe 20 is coaxially arranged with the corresponding through groove, and the stuffing cage 14 can move in the vertical pipe 20. The exhaust gas can only flow upward through the through groove through the vertical pipe 20. When the chain 13 drives the stuffing cage 14 to pass through the through groove, the exhaust gas will pass through the vertical pipe 20 and then enter the stuffing cage 14, thereby preventing the exhaust gas from directly flowing upward from the gap between the stuffing cage 14 and the through groove, and ensuring that the exhaust gas can enter the stuffing cage 14 for absorption and treatment.

[0019] Specifically, Figure 2 As shown, the baffle 7 and the vertical pipe 20 of this embodiment are provided with a first avoidance groove 30 corresponding to the chain 13, and a brush is provided in the first avoidance groove 30, which is not shown in the figure. The setting of the first avoidance groove 30 enables the chain 13 to operate normally, and the setting of the brush can hinder the flow of exhaust gas, reduce the flow of unabsorbed exhaust gas, and prevent unabsorbed exhaust gas from flowing away from the gap between the chain 13 and the first avoidance groove 30.

[0020] Further, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the packing cage 14 described in this embodiment is respectively fixedly mounted with a coaxial first gear 40, the inner periphery of the first gear 40 is fixedly connected to the outer wall of the packing cage 14, the first gear 40 is located at the largest diameter of the packing cage 14, the packing cage 14 is rotatably mounted on the chain 13, the front and rear sides of the packing cage 14 are respectively rotatably mounted with support shafts through bearings, the support shafts are fixedly mounted on the corresponding chains 13, a rotating rod 41 is rotatably mounted in the tank body 1, one end of the rotating rod 41 extends to the outside of the tank body 1 and is fixedly connected to the output shaft of the second motor 42, the two ends of the rotating rod 41 are respectively rotatably mounted in the reserved holes on the tank body 1 through sealed bearings, the rotating rod 41 is coaxially arranged with the output shaft of the second motor 42, the second motor 42 is fixedly mounted on the tank body 1, one side of the second motor 42 is also fixedly connected to the mounting plate, one side of the mounting plate is fixedly connected to the side wall of the tank body 1, a coaxial second gear 43 is fixedly mounted on the rotating rod 41, and the first gear 40 can mesh with the second gear 43 in sequence. When the chain 13 drives the filling cage 14 to move, and the first gear 40 on one of the filling cages 14 meshes with the second gear 43, the second motor 42 is started, and the second motor 42 drives the rotating rod 41 to rotate, thereby driving the second gear 43 to rotate, and the second gear 43 drives the filling cage 14 to rotate, so that the absorption liquid at the bottom of the tank body 1 flushes the filler in the filling cage 14, and the filling cage 14 is driven to rotate by the second motor 42, so that the cleaning effect is better, the flushing effect is improved, and the replacement of the filler is further reduced.

[0021] Furthermore, Figure 1 As shown, the second avoidance groove 50 is provided on the vertical pipe 20 and the partition plate 7 in this embodiment corresponding to the first gear 40. The second avoidance groove 50 allows the first gear 40 to pass through the through groove and the vertical pipe 20 without making the gap between the through groove, the vertical pipe 20 and the filling cage 14 too large.

[0022] Furthermore, Figure 1 As shown, a part of the spherical surface of the packing cage 14 described in this embodiment is rotatably connected to another part, a rod on the rotatable part of the packing cage 14 is installed in the fixed tube, the inner periphery of the fixed tube is frictionally contacted with the outer periphery of the rod, and the connection is coaxially arranged, the fixed tube is fixedly installed on the other part of the packing cage 14, and a limiting mechanism for limiting the relative rotation of its spherical surface is provided on the packing cage 14, and a material change pipe 61 is connected and installed on one side of the tank body 1, and a second sealing cover 62 is provided on the material change pipe 61 in a sealing manner, and the first sealing cover 62 is installed on the flange of the material change pipe 61 by bolts. After the absorption liquid in the tank body 1 is discharged, the second sealing cover 62 is removed, the restriction of the limiting mechanism is released, and the rotatable part of the packing cage 14 is opened, and the packing in the packing cage 14 can be taken out for replacement.

[0023] Furthermore, Figure 6As shown, the limiting mechanism of this embodiment includes a slot 70, which is provided on a rotatable part of the stuffing cage 14, and a corresponding slide groove 71 is provided on the other part. A plunger 73 is installed in the slide groove 71 through a spring 72. One end of the spring 72 is fixedly connected to the side wall of the slide groove 71, and the other end of the spring 72 is fixedly connected to the plunger 73. The plunger 73 is an L-shaped rod, which is composed of a rod in the front and rear directions and a vertical rod. One end of the plunger 73 is plugged into the slot 70. Push the plunger 73 upward, and the spring 72 is compressed until the plunger 73 is completely removed from the slot 70. At this time, the limit is released, and the rotatable part of the stuffing cage 14 can be opened. When the limit needs to be restored, the rotatable part of the stuffing cage 14 is closed, and the plunger 73 is inserted into the slot 70 under the action of the spring 72, and the limit is restored.
