Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization towers, and specifically to an exhaust gas desulfurization tower for silica gel production. Background Art

[0002] Silica gel is a highly active adsorbent material, usually prepared by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid soaking. Silica gel is an amorphous substance, insoluble in water and any solvent, non-toxic and odorless, with stable chemical properties, and does not react with any substance except strong alkalis and hydrofluoric acid. During the production of silica gel cat litter, a large amount of waste gas is generated, and the waste gas contains a large amount of sulfides. Direct emission will cause serious air pollution. Currently, wet flue gas desulfurization tower devices are commonly used for silica gel flue gas desulfurization. The main function of the desulfurization tower is to remove sulfur dioxide from the silica gel flue gas.

[0003] In the prior art, as disclosed in the patent application number: CN202022028237.4, a waste gas desulfurization tower for silica gel cat litter production is disclosed, which includes a tower body. An air inlet pipe is opened at the bottom of the tower body, and an air outlet pipe is opened at the upper part. The air inlet pipe passes through the tower body and is fixedly connected with a diffuser pipe. The diffuser pipe is composed of two annular pipes of different sizes and multiple straight pipes. A plurality of rows of air diffusion holes are arranged on the side surfaces of the large and small annular pipes and the straight pipes. A liquid delivery rod is rotatably connected inside the tower body. A motor is installed outside the bottom of the tower body. One end of the liquid delivery rod is rotatably connected to the top wall of the tower body, and the other end passes through the tower body and is connected to the output end of the motor. A liquid delivery sleeve is sleeved on the liquid delivery rod, and liquid delivery holes are opened in the part located inside the liquid delivery sleeve. A plurality of arm rods are fixedly connected to the liquid delivery rod, and a plurality of spray heads are fixedly connected to the plurality of arm rods. The bottom wall of the tower body is connected with a waste liquid treatment tank through a waste liquid pipe. The present invention ensures the reaction time of the waste liquid under the condition of uniform waste gas.

[0004] However, in the prior art, as mentioned in the waste gas desulfurization tower with the patent application number: CN202022028237.4, during actual use, although the waste gas can react uniformly, the lime water in the existing waste gas desulfurization tower is directly sprayed downward, while the waste gas, after being introduced into the tower body, directly ascends from the position where the pipeline is connected to the tower body, resulting in the silica gel waste gas being prone to too fast flow rate and being discharged without contacting the lime water for desulfurization, causing pollution. At the same time, after the reaction in the current flue gas desulfurization tower, precipitate impurities will be generated, and the accumulation of the precipitate impurities is prone to block the circulating spray mechanism. Therefore, it needs to be improved. Summary of the Invention

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides an exhaust gas desulfurization tower for silicone production, which has the following beneficial effects:

[0018] 1. In the present invention, the moving block blocks the chute block, forming an S-shaped channel inside the tower body, reducing the flow rate of the silicone exhaust gas, making the silicone exhaust gas more evenly purified and reacted by the second spraying block and the first spraying block, and making the precipitate after the purification reaction flow into the inside of the chute block for precipitation. Then, the driving mechanism drives the moving block and the blocking block respectively, so that the blocking block opens the sewage outlet, and the moving block releases the block on the chute block, so that the second spraying block can spray and wash the precipitate inside the chute block, and the precipitate is discharged through the sewage outlet, preventing the precipitate from blocking the second spraying block and the first spraying block through the circulating water supply mechanism.

[0019] 2. In the present invention, when the control box controls the blocking block to open the sewage outlet through the electric telescopic rod, the control box will first control the first valve pipe to close the air inlet pipe, so that the outside air cannot introduce the silicone exhaust gas into the inside of the tower body through the first connecting pipe and the air inlet pipe. Thus, the control box drives the blocking block to often open the sewage outlet through the electric telescopic rod, so that the precipitate inside the chute block can be discharged through the sewage outlet, avoiding too much precipitate inside the chute block from flowing into the inside of the circulating water supply mechanism and causing blockage of the first spraying block and the second spraying block.

[0020] 3. In the present invention, when the liquid level controller detects that the lime water in the circulating water tank is lacking, the liquid level controller will transmit the detection signal to the control box, so that the control box controls the opening of the second valve pipe. Then, the outside dosing device introduces the lime water into the circulating water tank through the second connecting pipe and the water inlet pipe. By starting the circulating water pump, the circulating water pump pumps the lime water inside the circulating water tank, and the lime water is introduced into the inside of the first spraying block and the second spraying block through the circulating pipeline and the circulating connecting pipe in sequence and sprayed to purify the silicone exhaust gas, ensuring the operation of the first spraying block and the second spraying block to circulate and spray the lime water to purify the silicone exhaust gas.

Detailed implementation manners

[0032] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually left and right as shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms are not used to limit the present invention.

[0033] Example 1. According to Figures 1 - 10 As shown in the figure, an exhaust gas desulfurization tower for silicone production includes a tower body 1. An air outlet 2 is provided at the upper end of the tower body 1. Inside the tower body 1, a first spraying block 3, a second spraying block 4 and an inclined groove block 6 are fixedly arranged in sequence. A moving block 5 located between the second spraying block 4 and the inclined groove block 6 is movably sleeved inside the tower body 1. The first spraying block 3, the second spraying block 4, the moving block 5 and the inclined groove block 6 divide the interior of the tower body 1 into an S-shaped channel. An air inlet pipe 7 fixedly communicated with the inside of the tower body 1 is located between the moving block 5 and the inclined groove block 6. A sewage discharge port 8 is opened inside the tower body 1 on the left side of the inclined groove block 6. A hinge block 9 is fixed on the side surface of the tower body 1. A blocking block 10 for closing the sewage discharge port 8 is hinged on the hinge block 9. A driving mechanism fixed on the tower body 1 is in transmission connection with the moving block 5 and the blocking block 10. The rear ends of the first spraying block 3 and the second spraying block 4 are fixedly communicated with a circulating water supply mechanism fixed under the tower body 1. The silicone waste gas is introduced into the inside of the tower body 1 through the air inlet pipe 7. At this time, since the first spraying block 3, the second spraying block 4, the moving block 5 and the inclined groove block 6 divide the interior of the tower body 1 into an S-shaped channel, the silicone waste gas will flow through the S-shaped channel and be discharged from the air outlet 2. During the flow of the silicone waste gas, the circulating water supply mechanism will respectively circulate and supply lime water into the first spraying block 3 and the second spraying block 4. The first spraying block 3 and the second spraying block 4 will carry out a spraying and purification reaction on the silicone waste gas flowing through the S-shaped channel. As a result, the lime water sprayed by the first spraying block 3 and the second spraying block 4 will be splashed respectively due to the blocking of the second spraying block 4 and the moving block 5. Furthermore, the splashed lime water will further react uniformly with the silicone waste gas. At this time, due to the design of the S-shaped channel, the second spraying block 4 and the first spraying block 3 will carry out a spraying and purification reaction on the silicone waste gas step by step, and effectively prevent the situation that the flow rate of the silicone waste gas is too fast, making the purification reaction of the silicone waste gas more sufficient. At the same time, due to the blocking of the moving block 5 on the inclined groove block 6, the sediment of the purification reaction of the silicone waste gas and the lime water can be washed into the inside of the inclined groove block 6 for precipitation, and the precipitated lime water will flow back into the circulating water supply mechanism again, so that the lime water can be circulated and guided into the first spraying block 3 and the second spraying block 4 for use through the circulating water supply mechanism, thus preventing the sediment from blocking the second spraying block 4 and the first spraying block 3;

[0034] When it is necessary to discharge the sediment inside the inclined groove block 6, at this time, the driving mechanism drives the moving block 5 and the blocking block 10 to move respectively, so that the blocking block 10 gradually opens the sewage discharge port 8, so that the sediment and lime water inside the inclined groove block 6 will be discharged through the sewage discharge port 8. At the same time, the moving block 5 will gradually move to the right to release the blocking of the inclined groove block 6, so that the second spraying block 4 can spray and wash the sediment inside the inclined groove block 6, and the sediment will be discharged through the sewage discharge port 8, thus achieving the purpose of conveniently discharging the sediment inside the inclined groove block 6.

[0035] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods. For details, see the following description.

[0036] Embodiment 2 is as follows Figures 4 - 10 As shown, the driving mechanism includes a convex rod 11 movably sleeved inside the tower body 1. A rotating block 12 located outside the tower body 1 is fixed to the left end of the convex rod 11. A sleeve block 13 is slidably sleeved inside the rotating block 12. A connecting block 14 located outside the rotating block 12 is fixed to one end of the sleeve block 13. A connecting rod 15 is limitedly sleeved inside the connecting block 14. The other end of the connecting rod 15 is fixedly connected to the moving block 5. A side through hole 16 is opened at the other end of the rotating block 12. A round plug rod 17 is movably sleeved inside the side through hole 16. The other end of the round plug rod 17 is fixedly connected to the blocking block 10. A side block 20 is fixed to one end of the connecting rod 15 and located on the front side of the connecting block 14. An electric telescopic rod 19 is drivingly connected to the side block 20. The other end of the electric telescopic rod 19 is fixedly connected to a fixed block 18. The other end of the fixed block 18 is fixedly connected to the outer surface of the tower body 1. When it is necessary to discharge the sediment inside the inclined chute block 6, at this time, the operator starts the electric telescopic rod 19, so that the electric telescopic rod 19 drives the connecting rod 15 to move through the side block 20. Furthermore, the connecting rod 15 drives the sleeve block 13 to move outwards along the rotating block 12 through the connecting block 14, and the connecting block 14 drives the rotating block 12 to rotate around the convex rod 11 as the axis through the sleeve block 13. Furthermore, the rotating block 12 drives the blocking block 10 to rotate and open the sewage outlet 8 through the side through hole 16 and the round plug rod 17, so that the sediment and lime water inside the inclined chute block 6 will be discharged through the sewage outlet 8. At the same time, the connecting rod 15 will drive the moving block 5 to move along the inner wall of the tower body 1, so that the moving block 5 gradually moves to the right to release the block on the inclined chute block 6, so that the spray block two 4 can spray and wash the sediment inside the inclined chute block 6, and the sediment is discharged through the sewage outlet 8, so as to achieve the purpose of separately driving the moving block 5 and the blocking block 10.

[0037] A sewage draining trough 32 is fixed to the side of the tower body 1 and located below the blocking block 10. The other end of the sewage draining trough 32 is located outside the tower body 1. Through the design of the sewage draining trough 32, the sediment discharged from the sewage outlet 8 will flow into the inside of the sewage draining trough 32, and then be discharged through the sewage draining trough 32 into the collection equipment below the tower body 1 for collection, avoiding the sediment from polluting the working environment outside the tower body 1.

[0038] A control box 25 is fixed to the side of the tower body 1. The control box 25 is electrically connected to the electric telescopic rod 19. Through the mutual cooperation between the control box 25 and the electric telescopic rod 19, the control box 25 can control the electric telescopic rod 19 to start at regular intervals, so that the electric telescopic rod 19 can drive the blocking block 10 to often open the sewage outlet 8, enabling the sediment inside the chute block 6 to be discharged through the sewage outlet 8, avoiding excessive sediment inside the chute block 6 from flowing into the internal part of the circulating water supply mechanism and causing blockage of the spraying block one 3 and the spraying block two 4.

[0039] One end of the air inlet pipe 7 is fixedly connected to a first valve pipe 27. The other end of the first valve pipe 27 is fixedly connected to a first connecting pipe 28 communicating with an external air guiding mechanism. The first valve pipe 27 is electrically connected to the control box 25. Through the mutual cooperation between the first valve pipe 27 and the control box 25, when the control box 25 controls the blocking block 10 to open the sewage outlet 8 through the electric telescopic rod 19, at this time, the control box 25 will first control the first valve pipe 27 to close the air inlet pipe 7, so that the external air guiding cannot introduce silicone waste gas into the tower body 1 through the first connecting pipe 28 and the air inlet pipe 7, thereby avoiding the discharge of silicone waste gas when the sewage outlet 8 is opened to discharge sediment and causing environmental pollution.

[0040] On the basis of Embodiment 1, the solution in Embodiment 2 is further refined and introduced in combination with the following specific working methods. For details, see the following description.

[0041] Embodiment 3, as Figures 3 - 8 shown, a water inlet pipe 29 is fixedly connected to the inside of the tower body 1. One end of the water inlet pipe 29 is fixedly connected to a second valve pipe 30. The other end of the second valve pipe 30 is fixedly connected to a second connecting pipe 31 communicating with an external dosing device. The second valve pipe 30 is electrically connected to the control box 25. When there is a shortage of lime water in the circulating water supply mechanism below the tower body 1, at this time, the control box 25 controls the second valve pipe 30 to open, so that the external dosing device can supplement lime water to the circulating water supply mechanism through the second connecting pipe 31 and the water inlet pipe 29, ensuring the operation of the circulating water supply mechanism to circulate and supply lime water to the spraying block one 3 and the spraying block two 4.

[0042] A liquid level controller 26 is fixed to the bottom of the inclined chute block 6. The lower end of the liquid level controller 26 extends into the circulating water supply mechanism. The liquid level controller 26 is electrically connected to the control box 25. Through the design of the liquid level controller 26 and the control box 25, when the liquid level controller 26 detects that the circulating water supply mechanism lacks lime water, at this time, the liquid level controller 26 will transmit the detection signal to the control box 25, so that the control box 25 controls the opening of the second valve pipe 30, and then the external dosing device introduces lime water into the circulating water supply mechanism through the second connecting pipe 31 and the water inlet pipe 29. When the liquid level controller 26 detects that there is enough lime water in the circulating water supply mechanism, at this time, the liquid level controller 26 will transmit the detection signal to the control box 25, so that the control box 25 controls the closing of the second valve pipe 30, and then the external dosing device cannot introduce lime water into the circulating water supply mechanism through the second connecting pipe 31 and the water inlet pipe 29.

[0043] The circulating water supply mechanism includes a circulating water tank 21 fixed below the tower body 1. The lower end of the circulating water tank 21 is fixedly communicated with a circulating water pump 22. The upper end of the circulating water pump 22 is fixedly communicated with a circulating pipeline 23. The upper end of the circulating pipeline 23 is fixed with two circulating connecting pipes 24. The other ends of the two circulating connecting pipes 24 are respectively fixedly communicated with the spraying block 1 3 and the spraying block 2 4. By starting the circulating water pump 22, the circulating water pump 22 pumps the lime water inside the circulating water tank 21, and introduces the lime water into the interiors of the spraying block 1 3 and the spraying block 2 4 through the circulating pipeline 23 and the circulating connecting pipes 24 in sequence, so that the spraying block 1 3 and the spraying block 2 4 can spray the lime water to purify the silica gel waste gas.

[0044] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
