DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 5 A kind of acid gas recovery and treatment equipment with protective function comprises an acid removal pipeline 1, one end of which is provided with an exhaust hole 4, and the other end of the acid removal pipeline 1 is penetrated by an air inlet pipe 2, the inside of the acid removal pipeline 1 is provided with a net tube 12, the outer wall of the net tube 12 is slidably connected with the inner wall of the acid removal pipeline 1, the side wall of the net tube 12 is provided with a sewage outlet 10, and the ends of the net tube 12 are fixed with baffles 11, the air inlet pipe 2 penetrates one of the baffles 11 and is rotatably connected with the baffle 11, and the other end of the baffle 11 is fixed with a fixing column 9, The fixed column 9 is connected to a rotating mechanism 5, which is used to drive the fixed column 9 to rotate, wherein an acid removal mechanism 8 is provided inside the net tube 12, and the acid removal mechanism 8 is used to remove the acid gas inside the net tube 12. A water storage tank 3 runs through the bottom of the acid removal pipeline 1, and the water storage tank 3 is movably connected to the bottom of the acid removal pipeline 1, and the top of the water storage tank 3 is open. The water storage tank 3 is connected to a driving mechanism 6, and the driving mechanism 6 is used to drive the water storage tank 3 to move. A cleaning mechanism 7 is provided inside the acid removal pipeline 1, and the cleaning mechanism 7 is used to clean the inner wall of the acid removal pipeline 1.

[0031] In this embodiment, when the equipment is recovering and treating the acid gas, the air inlet pipe 2 is connected to the external air suction device. Under the action of the air suction device, the acid gas enters the mesh tube 12 through the air inlet pipe 2. After the acid gas enters the mesh tube 12, it is deacidified by the acid removal mechanism 8. The alkaline solution sprayed by the acid removal mechanism 8 reacts with the acidic substances in the acid gas to neutralize, thereby achieving the purpose of acid gas recovery and treatment. The gas without acidic substances directly passes through the inside of the mesh and is finally discharged from the exhaust hole 4 at the end of the acid removal pipeline 1, thereby avoiding the damage of the acid gas generated in the starch production process to the staff or the equipment on the site, and playing an effective protective role. In addition, the acidic substances will produce salts and water during the neutralization reaction. The water directly passes through the mesh and falls into the water storage tank 3, and the salts accumulate in the mesh tube 12. When the water level inside the water storage tank 3 is When it reaches a certain depth, the lower end of the mesh drum 12 will be immersed in the water inside the water storage tank 3. At this time, the rotating mechanism 5 drives the fixed column 9 to rotate, and the fixed column 9 drives the mesh drum 12 to rotate through the baffle 11. While the mesh drum 12 rotates, on the one hand, the inner wall of the acid removal pipeline 1 is cleaned by the cleaning mechanism 7, which can avoid the corrosion of the inner wall of the acid removal pipeline 1 caused by long-term use of the equipment with acidic gases, and plays a protective role for the acid removal pipeline 1, effectively improving the service life of the equipment. In addition, while the mesh drum 12 rotates, it will also drive the sewage outlet 10 to flip. When the sewage outlet 10 turns to the bottom, the salt substances generated inside the mesh drum 12 will directly fall into the water storage tank 3. At this time, the driving mechanism 6 drives the water storage tank 3 to move downward, thereby moving the water storage tank 3 to the outside of the acid removal pipeline 1, thereby facilitating the staff to clean the salt substances on the inner wall of the mesh drum 12.

[0032] See also Figure 5 The cleaning mechanism 7 includes a cleaning cotton fixed on the outer wall of the net cylinder 12, and the cleaning cotton is located on the side of the outer wall of the net cylinder 12 opposite to the sewage outlet 10;

[0033] When the water level inside the water storage tank 3 reaches a certain depth, the cleaning cotton on the outer wall of the mesh drum 12 will be immersed in the water inside the water storage tank 3. At this time, the mesh drum 12 will drive the cleaning cotton to move in a circular motion while rotating. The cleaning cotton will contact the inner wall of the acid removal pipe 1 while moving in a circular motion. The inner wall of the acid removal pipe 1 is cleaned by the wet cleaning cotton, which can effectively avoid the corrosion of the inner wall of the acid removal pipe 1 caused by the acidic gas used by the equipment for a long time. The inner wall of the acid removal pipe 1 is cleaned by the water generated by the neutralization reaction. No external water source and tools are required, the structure is simple, and it is convenient for staff to operate.

[0035] When the water level inside the water storage tank 3 reaches a certain depth, the motor 54 is started, and the motor 54 drives the second gear 52 to rotate through the rotating rod 53, and the engagement of the second gear 52 with the first gear 51 drives the fixed column 9 to rotate, and then drives the mesh cylinder 12 to rotate. On the one hand, the salt substances inside the mesh cylinder 12 can be discharged in time, and on the other hand, the cleaning mechanism 7 can clean the inner wall of the acid removal pipeline 1.

[0036] See also Figure 4 The driving mechanism 6 includes a symmetrically distributed pressing plate 62 arranged inside the acid removal pipeline 1, and the pressing plate 62 is connected to the bottom of the acid removal pipeline 1 through an elastic component 63, wherein a slide plate 64 is fixed to the bottom of the pressing plate 62, and the slide plate 64 passes through the bottom of the acid removal pipeline 1 and is slidably connected to the bottom of the acid removal pipeline 1, and one end of the slide plate 64 passing through the bottom of the acid removal pipeline 1 is connected to the water storage tank 3, and a push plate 61 for squeezing one of the pressing plates 62 is fixed to the outside of the rotating rod 53;

[0037] When the water level inside the water tank 3 reaches a certain depth, the motor 54 drives the rotating rod 53 to rotate, and the rotating rod 53 drives the push plate 61 to rotate at the same time. During the rotation of the push plate 61, the pressure plate 62 will be squeezed, so that the pressure plate 62 drives the water tank 3 to move downward through the slide plate 64, and then the water tank 3 is moved to the outside of the acid removal pipeline 1, which is convenient for the staff to clean the water and salt substances inside the water tank 3.

The elastic component 63 can be a spring, and the bottom of the acid removal pipeline 1 is provided with an anti-skid gasket. The setting of the anti-skid gasket can increase the friction between the water tank 3 and the bottom of the acid removal pipeline 1, thereby ensuring the stability of the water tank 3 and preventing the water tank 3 from moving downward due to the increase of water inside it.

[0038] See also Figure 2 The outer wall of the water storage tank 3 is fixed with symmetrically distributed rotating shafts 65, and one end of the rotating shaft 65 away from the water storage tank 3 is rotatably connected to the slide plate 64;

[0039] The water storage tank 3 can be rotated by setting the rotating shaft 65. When the water storage tank 3 moves to the outside of the acid removal pipeline 1, the staff can directly turn the water storage tank 3 over to facilitate the staff to pour out the water and salt substances inside the water storage tank 3.

[0040] See also Figure 5 The deacidification mechanism 8 includes an atomizing nozzle 83 disposed inside the mesh tube 12, a hollow tube 82 is fixed at the bottom of the atomizing nozzle 83, and an end of the hollow tube 82 away from the atomizing nozzle 83 is connected to a water inlet pipe 81, wherein the water inlet pipe 81 passes through one of the baffles 11 and the fixed column 9 and is rotatably connected to the two, and the water inlet pipe 81 passes through one end of the deacidification pipeline 1 and is fixedly connected thereto;

[0041] When the acid gas is recovered and treated, the external alkaline solution enters the hollow tube 82 through the water inlet pipe 81 and is finally sprayed out from the atomizing nozzle 83. The alkaline solution is diffused by the atomizing nozzle 83, which can effectively increase the reaction area between the alkaline solution and the acid gas, thereby improving the treatment effect of the acid gas.

[0042] See also Figure 5 A support rod 84 is fixed to the outside of the hollow tube 82, and a brush plate 85 is fixed to one end of the support rod 84 away from the hollow tube 82;

[0043] When the mesh cylinder 12 rotates, its inner wall will contact the brush plate 85 , and the brush plate 85 can clean the inner wall of the mesh cylinder 12 during the rotation process, thereby preventing salt substances from adhering to the inner wall of the mesh cylinder 12 .

[0044] See also Figure 1-Figure 6 A method for recovering and treating acid gas with a protective function, the method uses the acid gas recovery and treatment equipment with a protective function as described above to recover and treat the acid gas, comprising the following steps:

[0045] S1, acid gas enters into the mesh tube 12 through the air inlet pipe 2;

[0046] S2, the atomizing nozzle 83 sprays alkaline solution to react with the acid gas to generate salt substances and water. The salt substances accumulate inside the mesh tube 12, and the water falls into the water storage tank 3;

[0047] S3, when the water level inside the water storage tank 3 reaches a certain depth, the motor 54 is started, and the motor 54 drives the net cylinder 12 to rotate through the rotating rod 53;

[0048] S4, while the net cylinder 12 rotates, on the one hand, the salt substances inside it are poured into the water storage tank 3, and on the other hand, the cleaning cotton is driven to rotate, thereby cleaning the inner wall of the acid removal pipeline 1;

[0049] S5, the rotating rod 53 drives the push plate 61 to rotate, the push plate 61 presses the pressing plate 62, and the pressing plate 62 drives the water storage tank 3 to move through the slide plate 64, thereby moving the water storage tank 3 to the outside of the acid removal pipeline 1.

[0050] Working principle: When the equipment is recovering and treating the acid gas, the acid gas enters the mesh tube 12 through the air inlet pipe 2. After the acid gas enters the mesh tube 12, the external alkaline solution enters the hollow tube 82 through the water inlet pipe 81, and is finally sprayed out from the atomizing nozzle 83. The alkaline solution is diffused by the atomizing nozzle 83, and the alkaline solution reacts with the acidic substances in the acid gas to neutralize, thereby achieving the purpose of acid gas recovery and treatment. When the acidic substances react with the neutralization reaction, salts and water will be produced. The water directly passes through the mesh holes and falls into the water storage tank 3, and the salts are accumulated in the mesh tube 12. When the water level in the water storage tank 3 reaches a certain depth, the cleaning cotton on the outer wall of the mesh tube 12 will be immersed in the water in the water storage tank 3. At this time, the motor 54 is started, and the motor 54 drives the second gear 52 and the push plate 61 to rotate through the rotating rod 53. The meshing of 52 with the first gear 51 drives the fixed column 9 to rotate, and then drives the mesh drum 12 to rotate. When the mesh drum 12 rotates, it will drive the cleaning cotton to move in a circular motion. When the cleaning cotton moves in a circular motion, it will contact the inner wall of the acid removal pipe 1. The inner wall of the acid removal pipe 1 is cleaned by the wet cleaning cotton, which can effectively avoid the corrosion of the inner wall of the acid removal pipe 1 caused by the acid gas used for a long time by the equipment. In addition, when the mesh drum 12 rotates, it will also drive the sewage outlet 10 to flip. When the sewage outlet 10 turns to the bottom, the salt substances generated inside the mesh drum 12 will directly fall into the water storage tank 3. At the same time, the push plate 61 squeezes the pressure plate 62, and the pressure plate 62 drives the water storage tank 3 to move downward through the slide plate 64, so that the water storage tank 3 moves to the outside of the acid removal pipe 1, which is convenient for the staff to clean the water and salt substances inside the water storage tank 3.
