Novel gas distributor

Abstract

The invention relates to a novel gas distributor. The novel gas distributor comprises a gas inlet, a stripy channel, a ring-shaped channel, a filtering net and distributing holes, wherein the gas inlet is of a cylindrical structure positioned at the central position of the gas distributor; the stripy distributing channel is of a horizontal columnar structure, one end of the stripy distributing channel is communicated with the gas inlet, and the other end of the stripy distributing channel is communicated with the ring-shaped distributing channel; the ring-shaped distributing channel is of a ring-shaped structure, and the two ends of the ring-shaped distributing channel are respectively communicated with the stripy distributing channel; the filtering net is positioned at an inlet of the stripy distributing channel; and the distributing holes are round through holes and are 6-10mm in hole diameter. The novel gas distributor has the advantages that gas outside a tower enters into the gas distributor through the gas inlet of the distributor, impurities and foams in the gas are removed by the filtering net, and then the gas flows into the whole distributing channel, flows out through the gas distributing holes uniformly distributed at the lower end of the channel, and is uniformly distributed to a treating layer, so that the condition of local concentration or dead zones is prevented, and the working efficiency of the gas distributor is greatly improved. The novel gas distributor is simple in structure and convenient in manufacture.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a gas distributor used in a chemical separation device. Background technique [0002] In chemical production, it is usually necessary to introduce the gas outside the tower into the tower to contact with the treatment layer (such as adsorption layer, catalyst layer, etc.) inside the tower for treatment or chemical reaction. However, directly passing the gas outside the tower into the tower will often cause uneven distribution of the gas, local concentration of gas or gas dead zone (no gas inflow), etc., which seriously affects the treatment effect and quality of the treatment layer in the tower. reaction efficiency. In order to avoid this situation, a gas distributor is often installed in the tower, so that the gas entering the tower can be evenly distributed to the treatment layer. At present, a commonly used gas distributor is a strip-shaped gas distributor. The gas flows ou...

AI Technical Summary

Problems solved by technology

At present, a commonly used gas distributor is a strip-shaped gas distributor. The gas flows out from the distribution holes at the lower end of the strip after passing through the air inlet. This kind of distributor can achieve uniform gas distribution to a certain extent, but there are also Some shortcomings, due to the use of strip distribution channels, the distribution point of gas distribution is reduced, and the gas introduced from outside the tower sometimes produces foam or impurities, which will block the gas distribution channels and directly reduce the gas distributor. distribution effect, which will greatly reduce the working effect of the treatment layer in the tower
