Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon adsorption devices, in particular to an activated carbon adsorption device for waste gas treatment. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health.

[0003] At present, in order to reduce air pollution, it is necessary to purify the waste gas from industrial sites and factory workshops before discharge. Activated carbon adsorption devices are usually used to treat waste gas. However, after a period of use, the existing activated carbon adsorption devices gradually become saturated due to the adsorption of a large amount of adsorbent on the surface, and lose their working ability. In severe cases, they will penetrate the filter layer. Therefore, we propose an activated carbon adsorption device for waste gas treatment to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide an activated carbon adsorption device for waste gas treatment, which can enable the activated carbon adsorption device to work continuously, increase the use efficiency of the activated carbon, and solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an activated carbon adsorption device for waste gas treatment, comprising a box body, the bottom of the box body is designed to be funnel-shaped and has a discharge port in the middle, support columns are fixedly installed around the bottom of the box body, a first support mesh plate is fixedly installed on one side of the box body near the top, a second support mesh plate is fixedly installed on one side of the box body near the bottom, the first support mesh plate and the second support mesh plate are parallel to each other and both face the discharge port, a motor is fixedly installed in the middle of the top of the box body, the output end of the motor is downward and fixedly connected to a rotating shaft, the One end of the rotating shaft away from the motor extends through the top plate of the box to the inside of the box and is rotatably connected to the upper surface of the first supporting mesh plate, a plurality of fixing rods extending toward the side wall of the box are fixedly installed around the rotating shaft, a shift rod is fixedly installed at one end of the fixing rod away from the rotating shaft, and the top of the first supporting mesh plate is filled with block activated carbon, a plurality of ultraviolet lamps are fixedly installed around the rotating shaft at the top of the box, a feeding port and an exhaust pipe are fixedly installed near the edge of the top of the box, an air inlet pipe is fixedly installed on the side of the box near the bottom, and a box door is installed in the middle of the side of the box.

[0006] The exhaust gas enters the box from the air intake pipe and passes through the second supporting mesh plate and the first supporting mesh plate in turn, and then the harmful substances in the exhaust gas are adsorbed by the block activated carbon. The motor controls the rotating shaft to drive the lever to stir the block activated carbon, thereby increasing the contact area between the block activated carbon and the exhaust gas, and causing the block activated carbon to collide with each other, thereby wearing out the surface, and continuously updating the surface adsorption effect of the block activated carbon. At the same time, the exhaust gas is irradiated with an ultraviolet lamp to accelerate the decomposition of harmful substances in the exhaust gas. The exhaust gas after adsorption is discharged through the exhaust pipe, and the fragments and debris produced by the wear of the block activated carbon fall to the bottom through the first supporting mesh plate. The larger fragments fall on the second supporting mesh plate, and the smaller ones fall on the bottom of the box, so that it can perform preliminary adsorption on the exhaust gas. When the block activated carbon is consumed, new block activated carbon is added through the feeding port. The fragments produced by the wear of the activated carbon accumulated on the second supporting mesh plate can be cleaned up by opening the box door, and the debris accumulated at the bottom of the box can be cleared through the discharge port.

[0007] Preferably, the discharge port and the feeding port are detachably provided with sealing covers, and when the discharge port and the feeding port are not in use, they are covered by the sealing covers to prevent exhaust gas from being discharged from the discharge port and the feeding port.

[0008] Preferably, the motor drives the rotating shaft to rotate, so that the rotating shaft drives the lever to stir the activated carbon blocks, so that the activated carbon blocks collide with each other to produce activated carbon fragments and activated carbon particles, the activated carbon fragments are accumulated on the second supporting mesh plate, and the activated carbon particles are accumulated at the bottom of the box. The collision of activated carbon blocks can not only continuously update the surface of the activated carbon blocks and maintain the best adsorption state, but also the activated carbon fragments and activated carbon particles produced by the collision can preliminarily adsorb the exhaust gas, thereby improving the adsorption efficiency and effect.

[0009] Preferably, one end of the exhaust pipe close to the box body extends through the box body to the interior thereof, and a support frame is fixedly installed around the exhaust pipe inside the box body.

[0010] Preferably, the support frame and the side wall of the box body surround the exhaust pipe, a filter plate is arranged below the exhaust pipe, and the four sides of the filter plate are fixedly connected to the bottom of the support frame and the side wall of the box body respectively. The filter plate prevents the activated carbon particles generated by the collision of the block activated carbon from being discharged along with the exhaust gas.

[0011] Preferably, one end of the air intake pipe close to the box body passes through the box body and extends to the inside thereof and is fixedly connected to an air guide pipe, one end of the air guide pipe away from the air intake pipe is closed and a plurality of air guide branch pipes are fixedly connected below the air guide pipe, and the lower end of the air guide branch pipe extends into the activated carbon particles. The exhaust gas enters the accumulated activated carbon particles through the air guide branch pipes, so that the activated carbon particles preliminarily adsorb the exhaust gas, thereby improving the adsorption efficiency.

[0012] Preferably, a sealing ring is fixedly installed at the connection between the box door and the box body to increase the sealing between the box door and the box body.

[0013] Preferably, the mesh size of the first support mesh is smaller than that of the block activated carbon, and the mesh size of the second support mesh is smaller than that of the first support mesh. The block activated carbon, activated carbon fragments and activated carbon particles are screened to facilitate subsequent cleaning.

[0014] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:

[0015] The utility model sets a first supporting mesh plate and a second supporting mesh plate, so that the exhaust gas enters the box body from the intake pipe and is filtered through activated carbon particles, activated carbon fragments and block activated carbon in sequence, and is finally discharged from the exhaust pipe through the filter screen, thereby improving the filtering effect; the motor drives the rotating shaft to drive the lever to stir the block activated carbon, so that the block activated carbon collides with each other, thereby wearing out the surface to generate new activated carbon fragments and activated carbon particles that fall below, so that the surface of the block activated carbon always maintains the best adsorption state, and the generated activated carbon fragments and activated carbon particles can be initially adsorbed, thereby improving the use efficiency of the activated carbon, improving the exhaust gas treatment effect, and realizing the purpose of the activated carbon adsorption device to continuously treat the exhaust gas; by installing an ultraviolet lamp on the top of the box body, the ultraviolet lamp irradiates the exhaust gas, which can accelerate the decomposition of harmful substances in the exhaust gas, and further improve the adsorption effect and efficiency of the activated carbon.
