Abstract

The invention relates to a gas distributor of an adsorption tower, and mainly solves the technical problems in the prior art that gas is unevenly distributed in an adsorbent bed layer and the adsorption effect is bad. The gas distributor of the adsorption tower is adopted and comprises a feed pipe (1), a pre-distributor (2) and a gas distribution pipe (3), one end of the pre-distributor (2) is connected with the feed pipe, the other end of the pre-distributor (2) goes deep into the interior of the adsorption tower, the pre-distributor (2) comprises an annular clearance (5) and a middle escape pipe (6), the middle escape pipe (6) is provided with a round hole near the diameter of the adsorption tower, the gas distribution pipe (3) is connected onto the pre-distributor (2) and is communicated with the annular clearance (5), and a round open hole (7) is formed in the gas distribution pipe (3). The technical scheme better solves the problems and can be applied to the industrial production of the gas adsorption tower.

Description

technical field

[0001] The invention relates to a gas distributor of an adsorption tower, in particular to a gas distributor of an adsorption tower used for purifying coal gas. Background technique

[0002] The main advantage of the axial flow fixed bed adsorption tower is that the flow of the fluid in the bed is close to plug flow, and the chemical reaction speed is faster; a larger production capacity can be obtained with a smaller amount of adsorbent and a smaller adsorption tower volume; The residence time can be strictly controlled, and the temperature distribution can be adjusted appropriately, which is beneficial to improve the conversion rate and selectivity of the chemical reaction. In addition, the axial fixed bed adsorption tower has simple structure, convenient operation, low investment cost, small mechanical wear of the adsorbent in the bed, and can be operated under high temperature and high pressure, so it is widely used in petrochemical industry.
