A gas purification adsorption tower based on environmental engineering

Abstract

This invention belongs to the field of environmental engineering technology and discloses a gas purification adsorption tower based on environmental engineering, including a tower body and a packing bin installed therein. An upper support is fixedly installed on the top of the tower body, and a spiral conveying roller is rotatably connected to the middle of the packing bin. The above scheme involves inputting organic waste gas from the top of the tower body, driving the blades and main shaft to rotate. This causes the spiral conveying roller to rotate, gradually transporting the packing layer at the bottom of the packing bin upwards and covering the entire activated carbon packing layer, thus covering the original packing. Simultaneously, the activated carbon at the top gradually falls to the bottom under gravity, thereby circulating the activated carbon layer. This method ensures that the activated carbon in the entire packing layer can uniformly contact the waste gas, avoiding premature saturation of the front section of the activated carbon adsorption layer, which would significantly hinder the gas flow path, thereby significantly improving the utilization rate of activated carbon and the operational stability of the adsorption tower.

Description

Technical Field

[0001] This invention belongs to the field of environmental engineering technology, specifically a gas purification adsorption tower based on environmental engineering. Background Technology

[0002] Activated carbon adsorption technology is a highly efficient and economical separation and purification method in environmental engineering. Its basic principle is to utilize the well-developed pore structure and huge specific surface area of ​​activated carbon to adsorb and enrich pollutants in waste gas on the solid surface through physical adsorption.

[0003] When purifying organic waste gas, the waste gas is fed into the adsorption tower. It enters the activated carbon packing layer and is adsorbed by its porous structure. The purified gas then passes through the activated carbon packing layer and is discharged. However, as the waste gas continuously passes through the stationary activated carbon layer, the adsorption process is not uniform throughout the entire bed but rather progresses gradually along the airflow direction. The activated carbon layer at the waste gas inlet first comes into contact with high-concentration pollutants, and its pores are rapidly filled, reaching saturation. At this point, the activated carbon layer loses its adsorption capacity and significantly obstructs the gas flow path. This results in the activated carbon in the later stages of the adsorption layer being in a fresh or unsaturated state, preventing the entire packing layer from effectively contacting and adsorbing pollutants in the waste gas. Consequently, the utilization rate of the entire activated carbon adsorption layer decreases significantly, seriously threatening the stable operation of the adsorption system.

[0004] Therefore, in order to solve the above problems, a gas purification adsorption tower based on environmental engineering is proposed. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a gas purification adsorption tower based on environmental engineering, which solves the problem that the front section of the activated carbon adsorption layer is prone to premature saturation, which would significantly hinder the gas flow path.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas purification adsorption tower based on environmental engineering, comprising a tower body and a packing bin installed therein, an upper support fixedly installed on the top of the tower body, a spiral conveying roller rotatably connected to the middle of the packing bin, a main shaft for driving the spiral conveying roller to rotate rotatably connected to the upper support, and a reduction gearbox for increasing speed and torque is provided between the packing bin and the main shaft. The packing chamber is porous and allows the upper and lower parts of the tower to be connected. A filter screen is provided on the upper surface of the packing chamber, and activated carbon packing is stored above the filter screen. The top of the main shaft is a blade, and the blade is located in the air inlet at the top of the tower.

[0007] Preferably, the reduction gearbox includes a frame fixedly installed inside the tower body and located above the packing bin and the spiral conveying roller. A gear ring is fixedly installed on the top of the spiral conveying roller. A plurality of planetary gears that mesh with the gear ring are rotatably connected to the lower part of the frame. The bottom end of the main shaft passes through the frame and is fixedly fitted with a sun gear that can mesh with the plurality of planetary gears. There are gaps between the bottom end of the main shaft and the lower surface of the planetary gear and the upper surface of the spiral conveyor roller.

[0008] Preferably, the inner surface of the packing chamber is an arc-shaped surface that can guide the activated carbon packing to the center of the packing chamber.

[0009] Preferably, a guide is fixedly installed in the middle of the packing bin. The upper surface of the guide is an arc-shaped surface whose height gradually decreases from the inner ring to the outer ring, and a channel is left between the lower surface of the guide and the arc-shaped surface.

[0010] Preferably, the support foot portion of the guide can pass through the filter screen and the packing chamber and extend below the packing chamber, and a vibration component for preventing activated carbon packing from accumulating on the guide is installed on the guide.

[0011] Preferably, the vibration assembly includes a plurality of spring push rods arranged in a ring and vertically movably installed in the guide member. Initially, the spring push rods are supported by their spring portions and have an upward tendency. The bottom end of the spring push rod is initially located below the filling chamber and is fixedly installed with a convex shaft. The bottom end of the spiral conveying roller is fixedly installed with a swing arm located below the filling chamber. One end of the swing arm is provided with a guide groove, and one end of the convex shaft can slide in the guide groove. The guide groove is in an inclined state, and the height of the guide groove is equal to the height of the convex shaft in the initial state.

[0012] Preferably, the guide groove can only accommodate one convex shaft for sliding at a time.

[0013] Preferably, a lower support is fixedly installed inside the tower body, located below the vibration assembly, and an air storage assembly for cleaning the blades is installed on the lower support.

[0014] Preferably, the gas storage assembly includes several sleeves fixedly sleeved on the lower support. A one-way valve is installed at the bottom of each sleeve, allowing one-way flow into the sleeve. A connecting pipe is fixedly connected to each sleeve. A gas storage rod is fixedly installed in the middle of the lower support. The other ends of the several connecting pipes are connected to the gas storage rod. A one-way valve is installed in each connecting pipe to restrict the one-way flow of gas from the sleeve to the gas storage rod. The top of the gas storage rod passes upward through the swing arm, the spiral conveying roller, and the main shaft and is connected to the top of the main shaft. The top of the main shaft has a number of air holes arranged in a ring array facing the blades. The bottom end of the spring push rod is a piston end and is vertically movably sleeved on the top of the sleeve; The blade is equipped with a valve assembly located below the swing arm to isolate the lower and upper parts of the gas storage rod, wherein the valve assembly can be opened intermittently.

[0015] Preferably, the valve body assembly includes a spring valve core rod movably mounted on the gas storage rod. In the initial state, the spring valve core rod can isolate the upper middle part and the bottom of the gas storage rod by its own elastic force. The spring valve core rod has an annular groove in the middle part and one end of the spring valve core rod can extend to the outside of the gas storage rod and is provided with an end. The bottom of the swing arm is provided with a fan-shaped component, which can squeeze the end to move when the swing arm rotates, and allow the upper middle and bottom of the gas storage rod to be connected through the annular groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The above scheme involves inputting organic waste gas from the top of the tower, driving the blades and main shaft to rotate. The high-speed rotation of the main shaft is reduced in speed and torque by a reduction gearbox, which then drives the screw conveyor roller to rotate slowly. The rotation of the screw conveyor roller gradually transports the packing layer at the bottom of the packing chamber upwards, covering the entire activated carbon packing layer and the existing packing. Simultaneously, the activated carbon at the top gradually falls to the bottom under gravity, thus circulating the activated carbon layer. This method ensures that the activated carbon in the entire packing layer can uniformly contact the waste gas, preventing the front section of the activated carbon adsorption layer from becoming saturated prematurely and significantly hindering the gas flow path. This significantly improves the utilization rate of activated carbon and the operational stability of the adsorption tower.

[0017] The above solution rotates the spiral conveyor roller while simultaneously driving the swing arm to rotate. At this time, the top of the guide groove causes the corresponding convex shaft to slide within it and forces the convex shaft to move downward within the guide groove. This causes the spring push rod to move downward and compress its spring portion to store energy. When the corresponding convex shaft disengages from the bottom of the guide groove, it quickly moves upward and resets under the action of the spring force of the spring push rod, impacting the guide component and causing it to vibrate. This allows the activated carbon filler on the upper surface of the guide component to quickly fill the upper layer of the filler in the filler bin.

[0018] The above solution involves transferring the gas in the corresponding sleeve through one-way valve two to the gas storage rod when the spring push rod moves downward. When the spring push rod moves upward and resets, external gas is replenished into the sleeve through one-way valve one. After the swing arm rotates one revolution, it will drive the extrusion end of the fan-shaped part to move, thereby connecting the bottom and upper middle part of the gas storage rod through the annular groove. At this time, the compressed gas in the gas storage rod will quickly enter the top of the main shaft through the top of the gas storage rod and be discharged through the air hole to blow onto the blades, thereby achieving a cleaning effect on the blades and preventing excessive deposits from adhering to them and affecting the rotation of the blades.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, the present invention provides a gas purification adsorption tower based on environmental engineering, including a tower body 1 and a packing bin 2 installed therein. An upper support 11 is fixedly installed on the top of the tower body 1. A spiral conveying roller 4 is rotatably connected to the middle of the packing bin 2. A main shaft 3 for driving the spiral conveying roller 4 to rotate is rotatably connected to the upper support 11. A reduction gearbox 5 for increasing speed and torque is provided between the packing bin 2 and the main shaft 3. Among them, the packing bin 2 is porous and can make the upper and lower parts of the tower body 1 interconnected. The upper surface of the packing bin 2 is provided with a filter screen 21, and the activated carbon packing is stored above the filter screen 21. The top of the main shaft 3 is a blade 31, and the blade 31 is located in the air inlet at the top of the tower body 1. The reduction gearbox 5 includes a frame 51 fixedly installed inside the tower body 1 and located above the packing bin 2 and the spiral conveying roller 4. A gear ring 54 is fixedly installed on the top of the spiral conveying roller 4. Several planetary gears 52 that mesh with the gear ring 54 are rotatably connected to the lower part of the frame 51. The bottom end of the main shaft 3 passes through the frame 51 and is fixedly fitted with a sun gear 53 that can mesh with several planetary gears 52. There are gaps between the bottom end of the main shaft 3 and the lower surface of the planetary gear 52 and the upper surface of the screw conveyor roller 4; Using the above scheme, organic waste gas is input from the top of the tower body 1, driving the blades 31 and the main shaft 3 to rotate. The high-speed rotation of the main shaft 3 drives the sun gear 53 to rotate, which in turn drives the gear ring 54 to rotate at a reduced speed via the planetary gears 52. At this time, the screw conveyor roller 4 is decelerated and its torque is increased, causing it to rotate slowly. The rotation of the screw conveyor roller 4 gradually transports the packing layer at the bottom of the packing bin 2 upwards, covering the entire activated carbon packing layer and the original packing. Simultaneously, the activated carbon at the top gradually falls to the bottom under gravity, thus circulating the activated carbon layer. This method allows the activated carbon in the entire packing layer to contact the waste gas evenly, avoiding premature saturation of the front section of the activated carbon adsorption layer, which would significantly hinder the gas flow path. This significantly improves the utilization rate of activated carbon and the operational stability of the adsorption tower.

[0023] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the inner surface of the packing chamber 2 is an arc-shaped surface 22 that can guide the activated carbon packing to the middle of the packing chamber 2; a guide 23 is also fixedly installed in the middle of the packing chamber 2. The upper surface of the guide 23 is an arc-shaped surface whose height gradually decreases from the inner ring to the outer ring, and a channel is left between the lower surface of the guide 23 and the arc-shaped surface 22. By adopting the above scheme, the arc-shaped part 22 and the guide 23 are set so that the guide 23 can guide the activated carbon packing layer after the spiral conveying roller 4 is transported upward and cover the upper layer of the packing layer. At the same time, the channel left between the arc-shaped part 22 and the guide 23 can ensure that the upper packing can gradually move downward and approach the middle of the packing bin 2.

[0024] like Figures 2-7 As shown, the support foot portion of the guide 23 can pass through the filter screen 21 and the packing chamber 2 and extend to the bottom of the packing chamber 2. A vibration component 6 is installed on the guide 23 to prevent activated carbon packing from accumulating on the guide 23. The vibration assembly 6 includes a ring array of several spring push rods 61 vertically movably mounted within the guide member 23. Initially, the spring push rods 61 are supported by their spring portions and tend to move upwards. The bottom end of the spring push rods 61 is initially located below the filling chamber 2 and a convex shaft 62 is fixedly installed thereon. The bottom end of the spiral conveying roller 4 is fixedly installed with a swing arm 63 located below the filling chamber 2. One end of the swing arm 63 has a guide groove 64, and one end of the convex shaft 62 can slide within the guide groove 64. The guide groove 64 is in an inclined state, and the height of the guide groove 64 is equal to the height of the convex shaft 62 in the initial state. The guide groove 64 can only accommodate one convex shaft 62 for sliding at a time. Using the above scheme, the rotation of the spiral conveyor roller 4 will also drive the swing arm 63 to rotate. At this time, the top of the guide groove 64 will cause the corresponding convex shaft 62 to slide in it and force the convex shaft 62 to move downward in the guide groove 64. This will cause the spring push rod 61 to move downward and compress its spring part to store force. When the corresponding convex shaft 62 is separated from the bottom of the guide groove 64, it will quickly move upward and reset under the action of the spring force of the spring push rod 61, impacting the guide member 23 and causing the guide member 23 to vibrate. This will enable the activated carbon filler on the upper surface of the guide member 23 to quickly fill the upper layer of the filler in the filler bin 2. It is worth noting that by limiting the sliding of only one cam 62 in the guide groove 64 at any given time, the pressure on the main shaft 3 and the blade 31 can be reduced, thus avoiding the situation where several cams 62 are forced to move downwards at the same time, which would reduce the rotational torque of the screw conveyor roller 4.

[0025] like Figures 3-8 As shown, a lower support 12 located below the vibration assembly 6 is fixedly installed inside the tower body 1, and an air storage assembly 7 for cleaning the blades 31 is installed on the lower support 12. The gas storage assembly 7 includes several sleeves 71 fixedly sleeved on the lower support 12. A one-way valve 72 is installed at the bottom of the sleeve 71 to allow one-way flow into the sleeve 71. A connecting pipe 74 is fixedly connected to the sleeve 71. A gas storage rod 73 is fixedly installed in the middle of the lower support 12. The other end of the several connecting pipes 74 is connected to the gas storage rod 73. A one-way valve 75 is installed in the connecting pipe 74 to restrict the one-way flow of gas in the sleeve 71 to the gas storage rod 73. The top of the air storage rod 73 passes upward through the swing arm 63, the spiral conveying roller 4, and the main shaft 3 and is connected to the top of the main shaft 3. The top of the main shaft 3 has a number of air holes 32 arranged in a ring array facing the blade 31. The bottom end of the spring push rod 61 is the piston end and is vertically movably sleeved on the top of the sleeve 71; A valve body assembly 8 is installed on the blade 31, located below the swing arm 63, to isolate the lower and upper parts of the gas storage rod 73. The valve body assembly 8 can be opened intermittently. The valve body assembly 8 includes a spring valve core rod 81 movably mounted on the gas storage rod 73. In the initial state, the spring valve core rod 81 can isolate the upper middle part and the bottom of the gas storage rod 73 by its own elastic force. The spring valve core rod 81 has an annular groove 82 in the middle part. One end of the spring valve core rod 81 can extend to the outside of the gas storage rod 73 and is provided with an end head 83. The bottom of the swing arm 63 is provided with a fan-shaped part 631. When the swing arm 63 rotates, the fan-shaped part 631 can squeeze the end 83 to move and make the upper middle and bottom of the gas storage rod 73 pass through the annular groove 82.

[0026] Using the above scheme, when the spring push rod 61 moves downward, the gas in the corresponding sleeve 71 is transported to the gas storage rod 73 through the one-way valve 75. When the spring push rod 61 moves upward and resets, the external gas will be replenished into the sleeve 71 through the one-way valve 72. After the swing arm 63 rotates one revolution, it will drive the extrusion end 83 of the fan-shaped part 631 to move, so that the bottom and upper middle part of the gas storage rod 73 are connected through the annular groove 82. At this time, the compressed gas in the gas storage rod 73 will quickly enter the top of the main shaft 3 through the top of the gas storage rod 73 and be discharged through the air hole 32 to blow onto the blade 31, thereby achieving the cleaning effect on the blade 31 and avoiding excessive deposits on it, which would affect the rotation of the blade 31.

[0027] Working principle and usage process of this invention: In operation, activated carbon packing is first filled into the packing chamber 2. Organic waste gas is input through the top of the tower body 1. The input airflow drives the blades 31 and the main shaft 3 to rotate. The high-speed rotation of the main shaft 3 is reduced in speed and torque by the reduction gearbox 5, which then drives the screw conveyor roller 4 to rotate slowly. The rotation of the screw conveyor roller 4 gradually transports the packing layer at the bottom of the packing chamber 2 upwards, covering the entire activated carbon packing layer and the existing packing. Simultaneously, the activated carbon at the top gradually falls to the bottom under gravity, thus circulating the activated carbon layer. This method ensures that the activated carbon in the entire packing layer can uniformly contact the waste gas, avoiding blockage and decreased adsorption efficiency caused by premature local saturation, significantly improving the utilization rate of activated carbon and the operational stability of the adsorption tower.

[0028] While the spiral conveyor roller 4 rotates, it also drives the swing arm 63 to rotate. At this time, the top of the guide groove 64 will cause the corresponding convex shaft 62 to slide inside it and force the convex shaft 62 to move downward in the guide groove 64. This causes the spring push rod 61 to move downward and compress its spring part to store force. When the corresponding convex shaft 62 is disengaged from the bottom of the guide groove 64, it will quickly move upward and reset under the action of the spring force of the spring push rod 61, impacting the guide member 23 and causing the guide member 23 to vibrate. This allows the activated carbon filler on the upper surface of the guide member 23 to quickly fill the upper layer of the filler in the filler bin 2.

[0029] When the spring push rod 61 moves downward, it will transport the gas in the corresponding sleeve 71 to the gas storage rod 73 through the one-way valve 75. When the spring push rod 61 moves upward and resets, the external gas will be replenished to the sleeve 71 through the one-way valve 72. After the swing arm 63 rotates one revolution, it will drive the extrusion end 83 of the fan-shaped part 631 to move, so that the bottom and upper middle part of the gas storage rod 73 are connected through the annular groove 82. At this time, the compressed gas in the gas storage rod 73 will quickly enter the top of the main shaft 3 through the top of the gas storage rod 73 and be discharged through the air hole 32 to blow onto the blade 31, thereby achieving the cleaning effect on the blade 31 and preventing too much deposits from adhering to it and affecting the rotation of the blade 31.
