Description

Technical Field

[0001] The utility model belongs to a smoke treatment device generated by a carbonization furnace, in particular to a smoke adsorption tower. Background Art

[0002] During the carbonization production process in the carbonization furnace, the flue gas needs to be treated, and activated carbon adsorption is a commonly used treatment link in flue gas treatment.

[0003] An activated carbon adsorption tower is usually used in the adsorption process. When the core of an existing activated carbon adsorption tower is saturated with adsorption, the internal adsorbent, i.e., activated carbon, needs to be replaced to achieve the desired adsorption effect again.

[0004] For example: Chinese invention CN201910755943.8 discloses a circulating mobile adsorption device for exhaust gas treatment, including an adsorption tank filled with adsorption material for adsorption treatment of exhaust gas and a desorption tank for receiving adsorbed adsorption material discharged from the adsorption tank and desorbing the adsorbed adsorption material, the desorption tank is connected to the adsorption tank by a desorbed adsorption material conveying device for conveying the desorbed adsorption material back to the adsorption tank; the top of the adsorption tank is provided with an adsorption tank feed pipe, the bottom of the adsorption tank is provided with an adsorption tank discharge pipe, the top of the desorption tank is provided with a desorption tank feed pipe, and the bottom of the desorption tank is provided with a desorption tank discharge pipe; the desorption tank is provided with a desorption gas inlet device for ensuring that the adsorption material can be desorbed and regenerated, and a desorption exhaust gas treatment device for treating the exhaust gas generated by the adsorption material during the desorption process;

[0005] The top inner end of the adsorption tank is provided with a leveling device for flattening the adsorption material in the adsorption tank so that the exhaust gas can fully contact the adsorption material; the middle and lower inner end of the adsorption tank is provided with a unloading device for ensuring that the adsorption material that has completed adsorption can fall down in time so that the adsorption material can be fully adsorbed; the adsorption tank located below the unloading device is connected to a tail gas intake device for introducing tail gas into the adsorption tank; the adsorption tank located above the leveling device and the bottom end of the desorption tank are connected to an exhaust gas exhaust device for discharging the adsorbed tail gas; an exhaust gas circulation device for allowing the exhaust gas to undergo multiple adsorption treatments is provided between the exhaust gas intake device and the exhaust gas exhaust device.

[0006] The device can effectively desorb the activated carbon used for adsorption and reuse it, thus realizing the recycling of the activated carbon.

[0007] However, in the prior art, the structure of the activated carbon core in the adsorption tank and the flow direction of the flue are not disclosed, and those skilled in the art cannot determine whether it is necessary to stop the furnace to empty the materials in the adsorption tank during circulation. Utility Model Content

[0008] Technical problem: The technical problem to be solved by the utility model is to provide an activated carbon adsorption tower, which is used in the treatment of flue gas generated by a carbonization furnace, and can replace the activated carbon core in the adsorption tower without stopping the furnace.

[0009] Technical solution: In order to solve the above technical problems, this application provides a new technical solution, as follows:

[0010] An adsorption tower includes a tower body and at least one activated carbon core body, the core body is vertically arranged inside the tower body, mesh holes are provided on the surface of the core body, a filling port is provided on the top, and a discharge port is provided on the bottom, and both the filling port and the discharge port are provided with a material inlet and outlet mechanism capable of blocking smoke, such as a star-shaped feeder. The vertically arranged core body can make the activated carbon inside fall naturally, which is convenient for the renewal and replacement of the activated carbon, and the star-shaped feeder provided at the filling port and the discharge port can block the smoke from overflowing from the filling port or the discharge port. Through this arrangement, the activated carbon can be renewed and replaced without stopping the furnace, which not only stabilizes the adsorption effect in real time, but also avoids the loss of carbonization production caused by stopping the furnace.

[0011] Furthermore, mesh holes are provided on two opposite side walls of the core body, and a cavity exists between the surface with the mesh holes and the tower body. The remaining two side walls are sealed and connected to the inside of the tower body, and the smoke passes through the core body in the cavity and is adsorbed before being discharged from the tower body.

[0012] Furthermore, the interior of the tower body is a chamber surrounded by the tower body side walls, and a number of cores divide the chamber into a number of vertical cavities. The existence of the cavity provides sufficient dust accumulation for the adsorption of flue gas containing a large amount of dust, so that excess dust is gathered in the cavity for subsequent cleaning, avoiding the rapid clogging of the porous structure of the activated carbon by dust, and improving the utilization rate of the activated carbon.

[0013] Furthermore, the tower body also includes partitions, which are respectively arranged in different cavities and arranged in a staggered manner in the horizontal direction. The staggered partitions divide the smoke channel into an S-shape, lengthen the smoke flow path, and make the smoke pass through the core body multiple times to achieve multiple adsorption effects.

[0014] Furthermore, the core body penetrates the top and bottom of the tower body, and a filling port is opened in the portion above the top;

[0015] The discharge port is set below the bottom. The side wall of the core extending out of the tower body is no longer meshed, and is fully enclosed to prevent smoke from overflowing.

[0016] Furthermore, two cores are arranged in the tower body, and the cores divide the chamber into a first cavity, a second cavity, and a third cavity. The two cores distributed in this way can increase the amount of activated carbon, thereby doubling the adsorption capacity that can be achieved, that is, the number of cores can increase the workload of the adsorption tower, and the number of times the flue gas passes through the core can be increased through the guidance of the partition, thereby achieving multiple adsorption.

[0017] Furthermore, a smoke inlet is provided on the lower side wall of the tower body, and a smoke outlet is provided on the top, and both the smoke inlet and the smoke outlet are provided in the second cavity.

[0018] Further, the partition includes at least a first partition, a second partition, a third partition, and a fourth partition;

[0019] The first partition is arranged on the first horizontal plane in the second cavity, the second partition and the third partition are arranged on the second horizontal plane in the first cavity and the third cavity respectively, and the fourth partition is arranged on the third horizontal plane in the second cavity. The first horizontal plane, the second horizontal plane and the third horizontal plane are arranged from low to high in sequence. Through the staggered partitions, the cavity formed by the two cores is formed into an S-shaped flue to achieve multiple adsorption treatment.

[0020] Furthermore, the partition completely seals and isolates the cavity into two upper and lower cavities.

[0021] Furthermore, at least two opposite sides of the partition are respectively embedded in the adjacent cores, increasing the path of the smoke in the core, avoiding incomplete adsorption caused by part of the smoke quickly entering and exiting the core along the side wall of the partition, and the embedded part of the side wall is preferably enlarged to make a bevel or arc edge to reduce the obstruction caused by the replacement of the activated carbon.

[0022] The beneficial effects of this application are:

[0023] 1. The activated carbon core is vertically arranged inside the tower body, so that the activated carbon inside can fall naturally, which is convenient for renewal and replacement. The filling port and the discharge port block the inlet and outlet of flue gas through the star-shaped feeding mechanism, so that the activated carbon can be replaced without stopping the furnace, avoiding production losses caused by stopping the furnace.

[0024] 2. The staggered arrangement of the partitions divides the smoke channel into an S shape, lengthens the smoke flow path, and allows the smoke to pass through the core multiple times, achieving a multiple adsorption effect.

[0025] 3. The cavity inside the tower body provides sufficient ash accumulation for the adsorption of flue gas with a large amount of dust. Excess dust can be gathered in the cavity for subsequent cleaning, avoiding dust clogging the porous structure of activated carbon and improving the utilization rate of activated carbon.

[0026] 4. By setting up multiple cores and corresponding partitions, the interior of the tower is divided into multiple vertical cavities. This can increase the amount of activated carbon, improve the workload of the adsorption tower, and increase the number of times the flue gas passes through the core through the guidance of the partition, thereby achieving multiple adsorption.

[0027] 5. The smoke inlet and smoke outlet of the tower body are arranged in the second cavity, and effective smoke treatment effect is achieved through reasonable smoke flow design. BRIEF DESCRIPTION OF THE DRAWINGS

The remaining two side walls are sealed and connected to the inside of the tower body 1, and the flue gas passes through the core body 2 in the cavity and is adsorbed before being discharged from the tower body 1.

[0037] The core 2 passes through the top and bottom of the tower body 1, and a filling port 4 is provided above the top; a discharge port 5 is provided below the bottom. The side wall of the core 2 extending out of the tower body 1 is no longer provided with mesh holes 3, and is fully enclosed to prevent the overflow of smoke.

[0038] Both the filling port 4 and the discharge port 5 are provided with star-shaped feeders. The vertically arranged core 2 can make the activated carbon inside fall naturally, which is convenient for the renewal and replacement of the activated carbon. The star-shaped feeders arranged at the filling port 4 and the discharge port 5 can block the smoke from overflowing from the filling port 4 or the discharge port 5. Through this arrangement, the activated carbon can be renewed and replaced without stopping the furnace, which not only stabilizes the adsorption effect in real time, but also avoids the loss of carbonization production caused by stopping the furnace.

[0039] The core 2 is designed inside the tower body 1 to expand outwards on both sides at the smoke inlet and outlet to increase the smoke inlet and outlet. Figure 1 As shown, the upper part of the core 2 is diagonally expanded to both sides to expand the smoke outlet and reduce the flow rate of the smoke. A plurality of smoke inlets and outlets may also be provided on the tower body 1, which are not shown in this embodiment.

[0040] The core 2 divides the chamber into a first cavity 6, a second cavity 7, and a third cavity 8. The two cores 2 distributed in this way can increase the amount of activated carbon, thereby doubling the adsorption capacity that can be achieved, that is, the number of cores 2 can increase the workload of the adsorption tower, and can also increase the number of times the flue gas passes through the core 2 through the guidance of the partition to achieve multiple adsorption.

[0041] A smoke inlet 9 is provided on the lower side wall of the tower body 1 , and a smoke outlet 10 is provided on the top. Both the smoke inlet 9 and the smoke outlet 10 are provided in the second cavity 7 .

[0042] The partitions include a first partition 11, a second partition 12, a third partition 13, and a fourth partition 14; the partitions completely seal and isolate the cavity where they are located into two upper and lower cavities.

[0043] The first partition 11 is arranged on the first horizontal plane in the second cavity 7, the second partition 11, the second partition 12 and the third partition 13 are arranged on the second horizontal plane in the first cavity 6 and the third cavity 8, respectively, the fourth partition 14 is arranged on the third horizontal plane in the second cavity 7, and the first horizontal plane, the second horizontal plane and the third horizontal plane are arranged from low to high in sequence. Through the staggered partitions, the cavity formed by the two core bodies 2 is formed into an S-shaped flue to achieve multiple adsorption treatment.

[0044] The opposite sides of the partition are respectively embedded in the adjacent core 2. The path of the flue gas in the core 2 is increased to avoid incomplete adsorption caused by the rapid entry and exit of part of the flue gas along the side wall of the partition. The embedded part of the side wall is preferably enlarged to make a bevel or arc edge to reduce the obstruction caused by the replacement of the activated carbon.
