Description

Adsorption cylinder and adsorption bed structure for catalytic adsorption and purification of gas Technical Field The utility model relates to the technical field of gas purification equipment, in particular to an adsorption cylinder and an adsorption bed structure for gas catalytic adsorption purification. Background Catalytic filtration purification is a conventional method of gas purification treatment. In the existing gas catalytic filtration and purification treatment technology, layered catalytic purification adsorbent particle materials are generally arranged in a gas flow channel to form an adsorbent bed, and then gas to be treated is driven to flow through the adsorbent bed, so that harmful components in the gas to be purified and the adsorbent are contacted and reacted, and the harmful components are trapped to realize filtration and purification. In some technologies, the adsorbent particles are supported on the porous material to form an adsorption material, but during the adsorption treatment, the gas to be treated is still driven to pass through the adsorption material for adsorption treatment. In the existing catalytic adsorption filtration mode, the gas to be treated generally passes through the adsorbent material in a unidirectional vertical direction, and the problems generally exist that 1 the contact-collision-reaction filtration flow of the gas to be treated and the adsorbent material is short, and the adsorption filtration efficiency is difficult to improve. 2 the gas to be treated passes through the adsorbent material in the vertical direction, so the reaction efficiency of the contact part of the adsorbent material and the gas to be treated is higher, the reaction efficiency of the contact part of the adsorbent material and the gas to be treated is lower, the non-uniformity of the reaction efficiency before and after the reaction efficiency can lead to the difficulty in controlling the whole regeneration time of the adsorbent, the non-uniformity of the purification efficiency before and after the reaction efficiency, and the whole purification effect and efficiency are reduced. And 3, the gas to be treated uniformly passes through the adsorbent material, and after the contact reaction between the adsorbent material at the front side and harmful substances, the volume is increased and pore channels are blocked, so that the blocking is caused, and the purification reaction efficiency of the subsequent adsorbent material is reduced. Therefore, how to better improve the adsorption efficiency, improve the utilization efficiency of the adsorbent material and facilitate the regeneration treatment of the adsorbent material is a direction of long-term effort improvement of the technicians in the field of catalytic adsorption, purification and filtration. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide an adsorption cylinder and an adsorption bed structure for gas catalytic adsorption purification, which can better improve the adsorption treatment purification efficiency, improve the utilization efficiency of an adsorbent material and facilitate the regeneration treatment of the adsorbent material. In order to solve the technical problems, the utility model adopts the following technical scheme: An adsorption cylinder for catalytic adsorption and purification of gas, which is cylindrical, is characterized in that, the adsorption cylinder is characterized in that a plurality of purification flow channels with sections gradually becoming smaller inwards are uniformly distributed on the peripheral wall of the adsorption cylinder, and a layer of catalytic adsorption material is arranged on the inner wall of each purification flow channel. In this way, the catalytic adsorption purification material is arranged on the inner wall of the purification flow channel with the diameter gradually decreasing in the advancing direction, so that the catalytic adsorption purification material contacts with the passing gas to realize the reaction purification of harmful components. When the gas is positioned at the inlet position of the rear end of the purifying flow channel, the corresponding purifying material area on the inner wall of the purifying flow channel is larger, and the cross section of the purifying flow channel is gradually reduced along with the forward flow of the gas along with the purifying flow channel, the area for adsorbing the purifying material is reduced, but the content of harmful components is also reduced along with the gradual purification of the gas, and the flow velocity is increased after the cross section of the purifying flow channel is reduced. Therefore, the purification rates at the front and rear parts of the purification flow channel can be kept high in consistency, the use uniformity of the adsorption material is improved, and the purification efficiency of the adsorption treatment can be better improved. Further, the i
