Description

Technical Field

[0001] The present application relates to the technical field of tail gas treatment, and in particular to an electrolyte tail gas condensation treatment device. Background Art

[0002] The tail gas released during the production of the electrolyte needs to be treated before it can be discharged into the atmosphere, and the tail gas treatment process is to first condense and cool it in a three-stage condensation tower, and then adsorb it through an activated carbon adsorption box and then discharge it through a fan. In the condensation tower, low-temperature water generated by heat exchange in the refrigerator exchanges heat with the tail gas, and the low-temperature water is passed into the neatly arranged heat exchange tubes distributed in the upper half of the condensation tower, while the tail gas is passed in from the bottom of the side. After the exhaust gas is cooled by the induced draft fan and heat exchanged with the heat exchange tubes, it flows out from the top of the condensation tower through the ventilation pipe to the bottom of the side of the next condensation tower. After the condensed water droplets reach a certain volume, they fall to the bottom of the inside of the condensation tower and are discharged through a pressure valve.

[0003] Because the condensed water is formed on the surface of the heat exchange tube, in the process of forming a certain volume on the surface of the heat exchange tube, it will continuously exchange heat with the low-temperature water in the heat exchange tube, which will cause the condensed water to retain a certain amount of cold and fall to the bottom of the condensation tower for discharge, increasing the loss of cold energy, increasing the load of the refrigerator, and reducing the heat exchange utilization rate of the cold energy. Summary of the invention

[0004] The present application proposes an electrolyte tail gas condensation treatment device, which has the advantages of reducing cold loss and improving heat exchange efficiency, and is used to solve the problems of cold loss and refrigeration load raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an electrolyte tail gas condensation treatment equipment, including a condensation tower, one side of the condensation tower is fixedly connected with an air inlet, the end of the air inlet away from the condensation tower is connected with a ventilation pipe for exhaust gas, and the top of each condensation tower is connected with the end of the ventilation pipe of the next level away from the air inlet, and the inner side of the condensation tower is fixedly connected with heat exchange tubes at equal distances horizontally and vertically, the upper layer of heat exchange tubes and the lower layer of heat exchange tubes on the inner side of the condensation tower are arranged with gaps, and connecting plates are fixedly connected between the end of one of the heat exchange tubes of the upper layer and the two closest ends of the heat exchange tubes of the lower layer, and the connecting plate is vertically arranged between the two heat exchange tubes of the upper and lower layers, and a vertical sliding groove is provided on the side of the connecting plate away from the heat exchange tube, and the connecting plate is slidably connected to a scraper plate through the sliding groove.

[0006] The cam is connected to the rear portion of the linkage set, and the rear portion is connected to the rear portion of the linkage set by the linkage set, so that the cam can be connected to the rear portion of the linkage set by the linkage set.

[0007] Furthermore, the cross-sectional shapes of the top end surface and the bottom end surface of the heat exchange tube are both inverted "V" shapes, and the heat exchange tube close to the inner wall of the condensation tower is a vertical half "V" shape, and the bottom end of the half "V" shape of the heat exchange tube close to the inner wall of the condensation tower is far away from the inner wall of the condensation tower.

[0008] Furthermore, the surface of the connecting plate is provided with heat exchange holes at equal distances in the horizontal and vertical directions, and the thickness of the connecting plate makes the two ends of the heat exchange holes far away from each other, and the end of the heat exchange hole close to the bottom surface of the upper heat exchange tube is higher than the end away from the bottom surface of the heat exchange tube.

[0009] Furthermore, the cross-sectional shape of the scraper plate is a rectangle with the bottom end close to the connecting plate and the top end away from the connecting plate, and the end of the scraper plate away from the connecting plate is located above the end of the scraper plate close to the connecting plate.

[0010] Furthermore, the bottom tangent of the central axis is parallel to the condensed water surface inside the condensation tower, and the central axis is located in the air inlet plane of the air inlet.

[0011] Furthermore, when the wind-bearing plate is moved from the top end of the wind-bearing plate being closer to the air inlet than the bottom end of the wind-bearing plate to the top end of the wind-bearing plate being farther away from the air inlet than the bottom end of the wind-bearing plate, the wind-bearing plate rotates to drive the central axis and the fixed column to wrap around the linkage rope. When the wind-bearing plate is moved from the top end of the wind-bearing plate being farther away from the air inlet than the bottom end of the wind-bearing plate to the top end of the wind-bearing plate being closer to the air inlet than the bottom end of the wind-bearing plate, the sliding rod pulls the linkage rope to drive the central axis, the fixed column and the wind-bearing plate to rotate.

[0012] Furthermore, when the sliding rod is at the top end of the inner side of the strip groove, the scraping plate is located at the bottom end of the outer side of the connecting plate.

[0013] The present application provides an electrolyte tail gas condensation treatment device, which, through the shape setting of the top end surface and the bottom end surface of the heat exchange tube, makes the condensed water attached to the top end surface and the bottom end surface of the heat exchange tube flow out to the two ends of the heat exchange tube due to its own gravity. Among them, the condensed water flowing to the two sides of the bottom end surface of the heat exchange tube will directly flow to the side surface of the connecting plate close to the bottom end of the heat exchange tube. Because the connecting plate is provided with a heat exchange hole inside, the end of the heat exchange hole close to the bottom end of the heat exchange tube forms a layer of water film due to the flow of condensed water, and then the water film is broken when the air flow passes through the heat exchange hole of the connecting plate, thereby enabling heat exchange between the tail gas and the condensed water, reducing the coldness in the condensed water, and the top end surface of the heat exchange tube slides to the condensed water on both sides, due to the top end surface of the heat exchange tube and the scraper The shape of the moving plate allows the condensed water to gather in the "V" shaped area formed by the heat exchange tube, the scraper plate and the inner wall of the condensation tower. As the condensed water continues to accumulate, the condensed water causes the scraper plate to slide downward again on the outside of the connecting plate due to its own gravity, so that the scraper plate can scrape on the side of the connecting plate away from the bottom end of the heat exchange tube, and the condensed water flows downward synchronously, forming a layer of water film again on the end of the heat exchange hole on the side of the connecting plate away from the bottom end of the heat exchange tube, thereby achieving the goal of forming a layer of water film at both ends of the heat exchange hole in the connecting plate, thereby enhancing the heat exchange effect between the exhaust gas and the condensed water, reducing the cold water flowing due to the condensed water, and increasing the instantaneous heat exchange of the exhaust gas through the two layers of film of the heat exchange hole.

Since the exhaust gas enters the inner side of the condensation tower 1 in a heat exchange and cooling process, the gas flow rate entering the inner side of the condensation tower 1 through the air inlet 2 is low, reference Figure 2 , Figure 3 , the inside of the condensation tower 1 is fixedly connected with heat exchange tubes 3 at equal distances horizontally and vertically, and the heat exchange medium required for condensation inside the condensation tower 1 is introduced into the inside of the heat exchange tubes 3. The upper layer of heat exchange tubes 3 and the lower layer of heat exchange tubes 3 on the inside of the condensation tower 1 are arranged with gaps, and the ends of one heat exchange tube 3 in the upper layer and the ends of the two closest heat exchange tubes 3 in the lower layer are respectively fixedly connected with connecting plates 4, and the connecting plates 4 are vertically arranged between the two heat exchange tubes 3 in the upper and lower layers, so that after the condensed water is generated, it slides from the top and bottom ends of the heat exchange tube 3 to the surface of the connecting plate 4, and only The condensed water continuously flows downward on the surface of the connecting plate 4, and then forms a water film on both sides of the connecting plate 4 close to or far away from the heat exchange tube 3 through the continuously flowing condensed water, thereby improving the heat exchange efficiency of the exhaust gas and reducing the loss of cold. A vertical sliding groove is provided on the side of the connecting plate 4 away from the heat exchange tube 3, and the connecting plate 4 is slidably connected to a scraper plate 5 through the sliding groove. The end side of the scraper plate 5 close to the connecting plate 4 is in close contact with the surface of the connecting plate 4, so that the scraper plate 5 can be pushed and moved by the condensed water to form a water film on the surface of the connecting plate 4.

[0026] Embodiment 2

[0027] Embodiment 2 is based on Embodiment 1. Please refer to Figure 2 The inner side of the condensation tower 1 is equidistantly connected to a central axis 6, and the outer side of the central axis 6 is fixedly connected to a wind bearing plate 7. Figure 4The top of the scraping plate 5 is fixedly connected with a connecting leather cord 8, and the top of the sliding groove inside the connecting plate 4 is provided with an "L"-shaped hole extending horizontally to the side of the connecting plate 4, and the connecting leather cord 8 extends from the sliding groove opened on the surface of the connecting plate 4 into the "L"-shaped hole and passes through the side of the connecting plate 4, and the outer side of the connecting leather cord 8 is sealed with the inner side of the "L"-shaped hole. The material of the connecting leather cord 8 is leather, refer to Figure 1 The back of the condensation tower 1 is fixedly connected with a spacer layer 9, and the spacer layer 9 and the back of the condensation tower 1 form a chamber, the spacer layer 9 and the condensation tower 1 are not connected, and the inner side of the spacer layer 9 is vertically provided with a strip groove 11 corresponding to the position of the same vertical scraper plate 5, and the inner side of the strip groove 11 is slidably connected with a sliding rod 10, reference Figure 4 The end of the connecting leather rope 8 passes through the side wall of the condensing tower 1 and the spacer layer 9 and is fixedly connected to the surface of the sliding rod 10 close to the condensing tower 1, and the point where the connecting leather rope 8 passes through the condensing tower 1 and the spacer layer 9 is located at the end position of the "L"-shaped hole on the side of each connecting plate 4, reference Figure 5 The center axis 6 is fixedly connected to the outside of the spacer layer 9 with a fixed column 12 located on the inside of the spacer layer 9, and the outside of the fixed column 12 is fixedly connected to a linkage rope 13. The top end of the linkage rope 13 is fixedly connected to the bottom end of the sliding rod 10, and the linkage rope 13 is an inelastic rope.

[0028] See also Figure 2 The cross-sectional shapes of the top and bottom surfaces of the heat exchange tube 3 are both in an inverted "V" shape, and the heat exchange tube 3 close to the inner wall of the condensation tower 1 is in a vertical half "V" shape, and the bottom end of the half "V" shape of the heat exchange tube 3 close to the inner wall of the condensation tower 1 is far away from the inner wall of the condensation tower 1. Through the shape setting of the top and bottom surfaces of the heat exchange tube 3, the condensed water formed on the top surface of the heat exchange tube 3 slides to the area formed by the heat exchange tube 3 and the scraper plate 5 for collection, and then the scraper plate 5 is pushed on the outside of the connecting plate 4 by the gravity of the continuously collected water. The scraper plate 5 scrapes the surface of the connecting plate 4 and the condensed water, and a mesh water film is formed on the side of the connecting plate 4 away from the bottom end of the heat exchange tube 3 through the heat exchange holes, thereby helping the heat exchange between the exhaust gas and the condensed water. The water condensed on the bottom end surface of the heat exchange tube 3 will flow to the surface of the connecting plate 4 on both sides of the heat exchange tube 3, and then the condensed water will form a water film again on the side of the connecting plate 4 close to the bottom end of the heat exchange tube 3 through the heat exchange holes. The cold energy in the condensed water is utilized through the two layers of water film at both ends of the heat exchange holes, thereby reducing the loss of cold energy.

[0029] See also Figure 6The surface of the connecting plate 4 is provided with heat exchange holes at equal distances horizontally and vertically, and the thickness of the connecting plate 4 makes the two ends of the heat exchange hole far away from each other, the end of the heat exchange hole close to the bottom surface of the upper heat exchange tube 3 is higher than the end away from the bottom surface of the heat exchange tube 3, and the axis of the heat exchange hole itself is perpendicular to the axis of the central axis 6. Through the high and low settings of the two ends of the heat exchange hole, when the condensed water collected between the heat exchange tube 3 and the scraper plate 5 on the side of the connecting plate 4 away from the bottom end of the heat exchange tube 3 flows downward, a certain amount of water flow will only flow on the side of the connecting plate 4 away from the bottom end of the heat exchange tube 3, reducing the influence of this part of the water flow on the water film formed on the side of the connecting plate 4 close to the bottom end of the heat exchange tube 3, thereby improving the utilization efficiency of the water film in the heat exchange hole.

[0030] See also Figure 3 The top of the scraper plate 5 is located above the end of the scraper plate 5 close to the connecting plate 4, and the scraper plate 5 is sealed against the inner wall side of the condensation tower 1 when the scraper plate 5 is located at the top of the outer side of the connecting plate 4. The scraper plate 5 is close to the side of the heat exchange tube 3 and the heat exchange tube 3 and the inner wall of the condensation tower 1 to form an area for collecting condensed water, so that the condensed water continues to gather inside this area, and the force of the condensed water on the scraper plate 5 continues to increase. When the water volume reaches a certain amount, the scraper plate 5 will be forced to move downward. Because of the oblique setting of the water exchange hole on the inner side of the connecting plate 4, the water volume at the top of the scraper plate 5 will not decrease in the initial stage of the downward movement of the scraper plate 5, thereby ensuring the effect of water gravity on the scraper plate 5, and further making the scraper plate 5 impart a water film to the surface of the connecting plate 4.

[0031] See also Figure 2 The bottom tangent of the central axis 6 is parallel to the condensed water surface inside the condensation tower 1. The central axis 6 is located in the air inlet plane of the air inlet 2. The wind-bearing plate 7 is synchronously located in the air inlet plane through the central axis 6. When the wind blows in through the air inlet 2, the wind-bearing plate 7 will be blown by the airflow to rotate clockwise, thereby driving the sliding rod 10 connected by the central axis 6, the fixed column 12 and the linkage rope 13 to move, so that the scraping plate 5 slides vertically on the surface of the connecting plate 4. At the same time, because the condensed water at the bottom will continuously exchange heat and cool with the ground and the external environment through the side wall of the condensation tower 1, The temperature of the condensed water falling from the top will be higher than that of the condensed water at the bottom. Therefore, at the moment when the condensed water at the top falls, the heat exchange area between the condensed water surface at the bottom and the exhaust gas will be reduced. Because the lower part of the wind-bearing plate 7 will enter the condensed water, when the wind-bearing plate 7 rotates, the condensed water surface will be directly stirred, and the falling condensed water will directly and quickly neutralize the temperature with the condensed water at the bottom, making the temperature of the bottom condensed water uniform, thereby ensuring that the initial heat exchange area between the exhaust gas that instantly enters through the air inlet 2 and the condensed water surface at the bottom is maximized.

[0032] See also Figure 2 , Figure 5 When the wind-bearing plate 7 is moved from the top end of the wind-bearing plate 7 being closer to the air inlet 2 than the bottom end of the wind-bearing plate 7 to the top end of the wind-bearing plate 7 being farther away from the air inlet 2 than the bottom end of the wind-bearing plate 7, the wind-bearing plate 7 rotates to drive the central axis 6 and the fixed column 12 to wrap around the linkage rope 13. When the wind-bearing plate 7 is moved from the top end of the wind-bearing plate 7 being farther away from the air inlet 2 than the bottom end of the wind-bearing plate 7 to the top end of the wind-bearing plate 7 being closer to the air inlet 2 than the bottom end of the wind-bearing plate 7, the sliding rod 10 pulls the linkage rope 13 to drive the central axis 6, the fixed column 12 and the wind-bearing plate 7 to rotate, that is, the clockwise rotation of the wind-bearing plate 7 is driven by wind force, and the counterclockwise rotation of the wind-bearing plate 7 is driven by water gravity, thereby achieving a transmission process at both ends through the connecting leather rope 8, the sliding rod 10, the linkage rope 13 and the fixed column 12.

[0033] See also Figure 2 By setting the wind-bearing plate 7, the central axis 6 and the wind-bearing plate 7 are located in the air inlet plane of the air inlet 2, and the flow rate of the exhaust gas is further reduced by the wind-bearing plate 7. At the same time, the condensed water collected on the side of the connecting plate 4 close to the scraping plate 5 has a large flow rate that flows down in an instant, which facilitates the formation of a thicker water film on the side of the connecting plate 4 close to the scraping plate 5, so that this part of the water film closes one end of the heat exchange hole, so that the airflow inside the heat exchange hole does not flow instantly, and then helps the formation of a water film on the side of the connecting plate 4 close to the bottom end of the heat exchange tube 3, so that the heat exchange exhaust gas passes through two layers of water film, thereby increasing the heat exchange between the condensed water and the exhaust gas.

[0034] See also Figure 5 When the sliding rod 10 is at the top of the inner side of the strip groove 11, the scraper plate 5 is located at the bottom of the outer side of the connecting plate 4. When the scraper plate 5 is pulled by the water gravity to slide the sliding rod 10, the sliding rod 10 slides on the inner side of the strip groove 11 to the top of the strip groove 11. At this time, the scraper plate 5 is located at the bottom of the outer side of the connecting plate 4. At the same time, the scraper plate 5 applies a water film to the surface of the connecting plate 4.

[0035] The method of use (working principle) of the present invention is as follows:

[0036] When the exhaust gas is condensed and cooled, the low-temperature water required for condensation is introduced from the inner side of the heat exchange tube 3, and the exhaust gas is introduced into the inner side of the condensation tower 1 from the inner side of the air inlet 2. The wind force pushes the wind-bearing plate 7 to rotate clockwise. While the wind-bearing plate 7 rotates, the fixed column 12 is driven to rotate clockwise through the central axis 6, so that the outer side of the fixed column 12 is wrapped with the linkage rope 13, so that the linkage rope 13 pulls the sliding rod 10 to slide downward, and the sliding rod 10 drives the connected connecting leather rope 8 to be pulled toward the bottom of the spacer layer 9, so that the connecting leather rope 8 drives the scraping plate 5 connected at the other end to slide upward on the outer side of the connecting plate 4, so that the scraping plate 5 is located at the outer top of the connecting plate 4. At the same time, the exhaust gas enters the inner side of the condensation tower 1 and is in contact with the exchange After heat exchange on the outside of the heat pipe 3, condensed water is formed. Due to the shape of the heat exchange tube 3, the condensed water slides to the two ends of the heat exchange tube 3. The condensed water on the bottom end surface of the heat exchange tube 3 will pass through the two connecting plates 4 close to the side of the heat exchange tube 3, so that the condensed water forms a water film at the end of each heat exchange hole in the connecting plate 4 close to the bottom end of the heat exchange tube 3. Because the connecting plate 4 is connected between the upper and lower adjacent heat exchange tubes 3, the connection between the two layers of heat exchange tubes 3 is isolated by the connection of the connecting plate 4, and the gas flow of the upper and lower layers is isolated, so that the gas can only pass through the heat exchange holes in the surface of the connecting plate 4, and then the water film is broken by the exhaust gas and the cold carried by the condensed water can be exchanged again before flowing into the upper heat exchange tube 3, so that the condensed water The cooling capacity in the heat exchange tube 3 is reduced. At the same time, the condensed water on the top surface of the heat exchange tube 3 will flow to the two ends of the heat exchange tube 3 due to the shape of the heat exchange tube 3, so that the condensed water flows to the area between the top surface of the heat exchange tube 3 and the scraper plate 5, and the condensed water gathers in this area. When the water continues to increase to the point where it can push and pull the scraper plate 5 to move downward on the outside of the connecting plate 4 again, the condensed water gathered between the scraper plate 5 and the heat exchange tube 3 will follow the movement of the scraper plate 5, and be scraped from the top of the side surface of the connecting plate 4 away from the bottom end of the heat exchange tube 3 to the bottom end of the connecting plate 4, thereby forming a water film at the end of each heat exchange hole in the connecting plate 4 away from the bottom end of the heat exchange tube 3, thereby making the connecting plate 4 close to the heat exchange tube 3 and away from the outside of the heat exchange tube 3 A double layer of water film is formed on the surface to enhance the heat exchange effect between the exhaust gas and the condensed water. When the scraper plate 5 moves downward on the outside of the connecting plate 4, the scraper plate 5 will synchronously pull the connected connecting leather rope 8 to move downward on the inside of the condensation tower 1, so that the connecting leather rope 8 pulls the sliding rod 10 connected to the inside of the spacer layer 9 to move upward, and then pulls the linkage rope 13 to rotate the wind-bearing plate 7 to release the linkage rope 13, so that the wind-bearing plate 7 at the bottom of the condensation tower 1 moves the bottom liquid level counterclockwise again, so that the side of the wind-bearing plate 7 close to the air inlet 2 faces the air inlet surface of the air inlet 2 for the exhaust gas to enter. The exhaust gas cooled by the heat exchange tube 3 passes out from the ventilation pipe at the top and enters the inner side of the next condensation tower 1 for cooling again.
