Description

Technical Field

[0001] The invention relates to the technical field of gas purification, in particular to a regenerable multi-stage particle activated coke adsorption tower. Background Art

[0002] As an important organic waste gas (mainly various volatile organic compounds) treatment equipment, activated coke adsorption tower is widely used. In the process of using activated coke adsorption tower to treat organic waste gas, the organic waste gas passes through the activated coke, and the activated coke uses its own adsorption capacity to adsorb the volatile organic compounds in the organic waste gas to achieve the purpose of purifying the air.

[0003] There are many existing technologies for adsorption tower devices, such as: Chinese patent publication number CN107537282A discloses a horizontal activated carbon adsorption tower, including a bracket, a driving motor is provided on the lower side wall of the bracket, and the output shaft of the driving motor is connected to a first rotating shaft arranged horizontally, a driving wheel is provided on the side of the first rotating shaft away from the driving motor, and two vertically arranged fixed blocks are symmetrically provided on the upper side wall of the bracket, and bearings are provided in both of the fixed blocks, a second rotating shaft is inserted in the bearing, and one end of the second rotating shaft passes through one side of the fixed block and is connected to a driven wheel, the driving wheel and the driven wheel are connected by a vertically arranged belt, and two gears are symmetrically sleeved on the outer side wall of the second rotating shaft. The present invention has a simple structure and is easy to operate. The structural design of the horizontal adsorption tower is compact and ingenious, so that the waste gas is treated more fully and thoroughly. At the same time, the activated carbon layer can be replaced at any time to ensure that the equipment can continue to work.

[0004] However, there are still some problems in actual use: 1. In the operation of traditional adsorption towers, when the activated coke particles are saturated with adsorption, they need to be replaced. However, the activated coke particles can continue to be used after being regenerated by heating. However, in actual operation, due to the lack of efficient regeneration supporting facilities and mature processes, the regeneration process is difficult to carry out smoothly. Enterprises often have to choose to frequently replace new activated coke particles, which not only greatly increases production costs, but also causes a huge waste of resources; 2. During the exhaust gas adsorption stage, the activated coke particles in the filling frame are in a relatively fixed position. The activated coke particles close to the gas channel can preferentially and fully contact the exhaust gas, and the adsorption process is faster, and it is very easy to reach the adsorption saturation state first. However, the activated coke particles far away from the gas channel have relatively less contact with the exhaust gas due to limited gas diffusion, and the adsorption speed is slow, resulting in their adsorption capacity not being fully utilized. This significant difference in adsorption efficiency seriously affects the overall adsorption effect and utilization rate of the activated coke.

[0005] In view of this, we propose a regenerable multi-stage granular activated coke adsorption tower. Summary of the invention

[0006] The object of the present invention is to provide a regenerable multi-stage granular activated coke adsorption tower to solve the problems raised in the above background technology.

[0008] As a further improvement of the technical solution, a gas channel is opened at the center of the filling frame, and the diameter of the gas channels is the same as that of the air inlet, and the gas is purified through the air inlet, the gas channel and the air outlet in sequence.

[0009] As a further improvement of the technical solution, a plurality of groups of filling frames are provided inside the tower body, and the filling frames are arranged in an array, and the active coke particles inside the filling frames close to the air inlet are saturated first.

[0011] As a further improvement of the technical solution, the heating port of the heating device is arc-shaped, and the heating device moves horizontally under the tower body.

[0012] As a further improvement of the technical solution, a column tube is provided on the side wall of the movable seat, a sliding rod is slidably provided on the inner wall of the column tube, a compression spring is provided between the column tube and the sliding rod, and a suction cup is provided at the end of the sliding rod, and the suction cup is adsorbed on both sides of the bottom of the heating device for fixation.

[0013] As a further improvement of the present technical solution, the rotating assembly includes an extension seat arranged on one side of the support frame, a servo motor is provided on the surface of the extension seat, a first gear is provided at the output end of the servo motor, a fixed gear is provided on one side of the first gear, the fixed gear is fixed on the surface of the tower body, and the rotation of the first gear drives the fixed gear to mesh and rotate.

[0014] As a further improvement of the technical solution, the buffer assembly includes a support rod arranged on the inner wall of the filling frame, a baffle is rotatably provided on the surface of the support rod, and a torsion spring is provided between the baffle and the filling frame.

[0015] As a further improvement of the technical solution, the torsion springs are arranged in a ring array inside the filling frame, and there is a gap between the baffle and the filling frame, and the active coke particles can pass through the gap.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the renewable multi-stage granular activated coke adsorption tower, multiple groups of filling frames are arranged in sequence inside the tower body. The multi-stage structure prolongs the contact time between the fluid and the activated coke. Compared with single-stage adsorption, the fluid must pass through multiple activated coke layers in the multi-stage adsorption tower in sequence, which increases the contact opportunities between pollutants and the adsorption sites on the surface of the activated coke, thereby greatly improving the adsorption efficiency and the exhaust gas purification effect.

[0017] 2.

Since a heating device is provided on the surface of the moving seat, the heating device is arc-shaped and can completely fit the bottom of the tower body for heating, so that the heating range is more uniform. The surface of the tower body is heated by the heating device. Since the tower body is made of metal material with thermal conductivity, when the tower body is heated, the heat is transferred to the surface of the filling frame provided inside. When the filling frame is heated, the activated coke particles inside are heated, so that the organic matter adsorbed in the gaps of the activated coke is volatilized, thereby increasing the service life of the activated coke and reducing the production cost.

[0018] 3. In the renewable multi-stage particle activated coke adsorption tower, the internal space of the filling frame is divided by a baffle, so that the activated coke particles are blocked by the baffle when rotating inside the filling frame, reducing the collision and breakage of the activated coke particles, thereby ensuring the adsorption effect of the activated coke particles. At the same time, there is a gap between the baffle and the filling frame. When the filling frame rotates, the activated coke particles inside it are slightly hit by the surface of the baffle due to inertia, so that the activated coke particles in different spaces interact with each other, thereby avoiding the active coke particles from adhering to each other, and improving the adsorption effect of the activated coke particles on polluted gases.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] As an important organic waste gas treatment equipment, activated coke adsorption tower is widely used. In the process of using activated coke adsorption tower to treat organic waste gas, the organic waste gas passes through activated coke, and the activated coke uses its own adsorption capacity to adsorb the volatile organic matter in the organic waste gas to achieve the purpose of purifying the air. At present, in the traditional adsorption tower process, when the activated coke particles are saturated with adsorption, they need to be replaced. However, the activated coke particles can continue to be put into use after regeneration treatment such as heating. However, in actual operation, due to the lack of efficient regeneration supporting facilities and mature processes, the regeneration link is difficult to carry out smoothly. Enterprises often have to choose to frequently replace new activated coke particles, which not only greatly increases production costs, but also causes a huge waste of resources.

[0024] The purpose of this embodiment is to provide a regenerable multi-stage particle activated coke adsorption tower, see Figure 1-Figure 7 As shown, it includes a support frame 100, bearing seats 101 are arranged on both sides of the top of the support frame 100, a tower body 102 is arranged between the bearing seats 101, an air inlet 103 and an air outlet 104 are respectively opened at both ends of the tower body 102, a filling frame 200 is arranged inside the tower body 102, a sealing plate 201 is arranged at the end of the filling frame 200, the filling frame 200 is filled with activated coke particles, a heating component 300 is arranged under the tower body 102, the heating component 300 is used to heat the surface of the tower body 102, the heated tower body 102 transfers heat to the filling frame 200 to heat the activated coke particles, a rotating component 400 is arranged on one side of the tower body 102, the rotating component 400 is used to drive the tower body 102 to rotate, so that the filling frame 200 fixed inside the tower body 102 is evenly heated, and a buffer component 500 is arranged inside the filling frame 200, the buffer component 500 is used to buffer the activated coke particles rotating inside the filling frame 200, so as to reduce the collision and breakage of the activated coke particles.

[0025] The improvement of the present invention lies in that the internal space of the filling frame 200 is divided by the baffle 502, so that the active coke particles are blocked by the baffle 502 when rotating inside the filling frame 200, reducing the collision and breakage of the active coke particles, thereby ensuring the adsorption effect of the active coke particles. At the same time, there is a gap between the baffle 502 and the filling frame 200. When the filling frame 200 rotates, the active coke particles inside it are slightly hit by the surface of the baffle 502 due to inertia, so that the active coke particles in different spaces interact with each other, thereby avoiding the adhesion of the active coke particles, thereby improving the adsorption effect of the active coke particles on the polluted gas.

[0026] In the process of purifying the gas, in order to facilitate the adsorption of harmful gases, a gas channel 202 is opened at the center of the filling frame 200. The diameter of the channels of the gas channel 202 is the same as that of the air inlet 103. The gas is purified in turn through the air inlet 103, the gas channel 202 and the air outlet 104. By arranging the filling frame 200 inside the tower body 102, since the filling frame 200 is filled with activated coke particles, the harmful gas molecules first diffuse outward through the activated coke particles, that is, the harmful gas molecules diffuse from the gas phase through the boundary layer to the outer surface of the activated coke particles, and then diffuse inward, and the gas molecules diffuse from the outer surface of the activated coke particles through the pore channels to the inside of the particles. This process allows the gas molecules to penetrate into the pores inside the activated coke for adsorption, thereby achieving gas purification.

[0027] In the process of purifying the exhaust gas, in order to improve the purification effect, a plurality of groups of filling frames 200 are provided inside the tower body 102, and the filling frames 200 are arranged in an array. The active coke particles inside the filling frames 200 close to the air inlet 103 are saturated first. By sequentially arranging a plurality of groups of filling frames 200 inside the tower body 102, the multi-stage structure prolongs the contact time between the fluid and the active coke. Compared with single-stage adsorption, the fluid must pass through multiple active coke layers in the multi-stage adsorption tower in turn, which increases the contact opportunities between the pollutants and the adsorption sites on the surface of the active coke. For example, in exhaust gas treatment, the exhaust gas may only stay for a few seconds in a single-stage adsorption tower, but in a multi-stage adsorption tower, due to the layer-by-layer adsorption effect, the total contact time may be extended to more than ten seconds or even dozens of seconds, thereby greatly improving the adsorption efficiency and improving the exhaust gas purification effect.

[0028] When the activated coke particles inside the filling frame 200 are saturated with adsorption, pollutants such as organic matter adsorbed in the pores of the activated coke can be volatilized through high-temperature heating, so as to be reused. Therefore, the heating component 300 includes a rotating motor 301 arranged on one side of the support frame 100, a screw rod 302 is arranged at the output end of the rotating motor 301, a movable seat 303 is arranged on the surface of the screw rod 302, and a heating device 304 is arranged above the movable seat 303. The heating device 304 is used to heat the bottom of the tower body 102. The heating port of the heating device 304 is arc-shaped, and the heating device 304 moves horizontally below the tower body 102. When the activated coke particles in the filling frame 200 are saturated with adsorption, the output end of the gas outlet 104 is connected to the purification device to purify the organic matter volatilized from the heated activated coke. The collecting and purifying is performed by controlling the output end of the rotating motor 301 to drive the screw rod 302 to rotate. When the screw rod 302 rotates, it drives the moving seat 303 to move horizontally under the tower body 102. Since the surface of the moving seat 303 is provided with a heating device 304, the heating device 304 is arc-shaped and can completely fit the bottom of the tower body 102 for heating, so that the heating range is more uniform. The surface of the tower body 102 is heated by the heating device 304. Since the tower body 102 is made of metal and has thermal conductivity, when the tower body 102 is heated, the heat is transferred to the surface of the filling frame 200 provided inside. When the filling frame 200 is heated, the activated coke particles inside are heated, so that the organic matter adsorbed in the gaps of the activated coke is volatilized, thereby increasing the service life of the activated coke and reducing the production cost.

[0029] Considering that the position of the heating device 304 is easily deviated due to inertia during the movement, resulting in the displacement of the heating position, which affects the purification efficiency of the activated coke particles, a column 305 is provided on the side wall of the moving seat 303, and a slide bar 306 is slidably provided on the inner wall of the column 305. A compression spring 307 is provided between the column 305 and the slide bar 306, and a suction cup 308 is provided at the end of the slide bar 306. The suction cup 308 is fixed on both sides of the bottom of the heating device 304, and the slide bar 306 is driven to slide on the column 305 by squeezing the suction cup 308. During the sliding process of the slide bar 306, the compression spring 307 is squeezed to deform the inner wall, and the space between the suction cups 308 is increased during the squeezing process. The heating device 304 is placed between the suction cups 308, and the squeezing of the suction cups 308 is stopped. The slide bar 306 is pushed by the reverse force of the compression spring 307, so that the suction cup 308 provided at the end of the slide bar 306 is adsorbed on the side wall of the heating device 304 for fixation, so that the heating device 304 remains stable during the horizontal movement, thereby ensuring the heating effect on the activated coke particles.

[0030] Considering that when the activated coke particles inside the filling frame 200 are heated, since the heating device 304 can only heat the bottom of the tower body 102, the heating effect of the activated coke above the filling frame 200 is poor, which affects the secondary utilization of the adsorbed saturated activated coke particles. Therefore, the rotating component 400 includes an extension seat 401 arranged on one side of the support frame 100, and a servo motor 402 is arranged on the surface of the extension seat 401. The output end of the servo motor 402 is provided with a first gear 403, and one side of the first gear 403 is provided with a fixed gear 404. The fixed gear 404 is fixed on the surface of the tower body 102. The rotation of the first gear 403 drives the fixed gear 404 to engage and rotate. By controlling the heating device 304 to move to the corresponding bottom of the filling frame 200, the servo motor 402 is started to drive the first gear 403 to rotate. When the first gear 403 rotates, it drives the fixed gear 404 to engage and rotate. When the fixed gear 404 rotates, the tower body 102 rotates on the inner wall of the bearing seat 101, so that the activated coke particles in the filling frame 200 are evenly heated, and the service life of the activated coke particles is improved.

[0031] Considering that when the tower body 102 drives the filling frame 200 to rotate, the active coke particles filled in the filling frame 200 are easy to rub and collide with each other, resulting in particle breakage, which affects the adsorption efficiency of harmful gases. Therefore, the buffer component 500 includes a support rod 501 arranged on the inner wall of the filling frame 200, and a baffle 502 is provided on the surface of the support rod 501 for rotation. A torsion spring 503 is arranged between the baffle 502 and the filling frame 200. The torsion spring 503 is arranged in a circular array inside the filling frame 200. There is a gap between the baffle 502 and the filling frame 200. The active coke particles can pass through the gap and impact the filling frame through the baffle 502. The internal space of filling frame 200 is divided so that the activated coke particles are blocked by baffle 502 when rotating inside filling frame 200, thereby reducing the collision and breakage of the activated coke particles and ensuring the adsorption effect of the activated coke particles. At the same time, in order to prevent the activated coke from accumulating in the same space for a long time and being adsorbed together, a gap is provided between baffle 502 and filling frame 200. When filling frame 200 rotates, the activated coke particles inside thereof are slightly hit against the surface of baffle 502 by inertia, so that the activated coke particles in different spaces interact with each other, thereby preventing the activated coke particles from adhering to each other and improving the adsorption effect of the activated coke particles on polluted gases.

[0032] When used specifically, a filling frame 200 is arranged inside the tower body 102. Since the filling frame 200 is filled with activated coke particles, gas molecules diffuse from the outer surface of the activated coke particles to the inside of the particles through the pore channels. This process allows the gas molecules to penetrate into the pores inside the activated coke for adsorption, thereby purifying the gas. By sequentially arranging multiple groups of filling frames 200 inside the tower body 102, the multi-stage structure prolongs the contact time between the fluid and the activated coke. Compared with single-stage adsorption, the fluid must sequentially pass through multiple activated coke layers in the multi-stage adsorption tower, which increases the contact opportunities between the pollutants and the adsorption sites on the surface of the activated coke, thereby greatly improving the adsorption efficiency and the exhaust gas purification effect. The output end of the control rotating motor 301 drives the screw rod 302 to rotate. When the screw rod 302 rotates, it drives the moving seat 303 to move horizontally below the tower body 102. Since the surface of the moving seat 303 is provided with a heating device 304, the heating device 304 is arc-shaped and can completely fit the bottom of the tower body 102 for heating, so that the heating range is more uniform. The surface of the tower body 102 is heated by the heating device 304. Since the tower body 102 is made of metal material with thermal conductivity, when the tower body 102 is heated, the heat is transferred to the surface of the filling frame 200 provided inside. When the filling frame 200 is heated, the active coke particles inside are heated, so that the organic matter adsorbed in the gaps of the active coke is volatilized, thereby increasing the service life of the active coke and reducing the production cost. The output end of the servo motor 402 drives the first gear 403 to rotate, and when the first gear 403 rotates, it drives the fixed gear 404 to mesh and rotate. When the fixed gear 404 rotates, the tower body 102 rotates on the inner wall of the bearing seat 101. When the heating device 304 heats the bottom of the tower body 102, the heated tower body 102 transfers heat to the filling frame 200 to heat the activated coke particles, so that the activated coke particles in the filling frame 200 are evenly heated, thereby improving the service life of the activated coke particles. At the same time, the tower body 102 can drive the filling frame 200 to rotate, so that the activated coke particles filled in the filling frame 200 are evenly mixed, thereby improving the adsorption effect of the activated coke.

[0033] The baffle 502 is used to divide the internal space of the filling frame 200 so that the activated coke particles are blocked by the baffle 502 when rotating inside the filling frame 200, thereby reducing the collision and breakage of the activated coke particles and ensuring the adsorption effect of the activated coke particles. At the same time, there is a gap between the baffle 502 and the filling frame 200. When the filling frame 200 rotates, the activated coke particles inside it slightly hit the surface of the baffle 502 due to inertia, so that the activated coke particles in different spaces interact with each other, thereby preventing the activated coke particles from adhering to each other and improving the adsorption effect of the activated coke particles on polluted gases.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
