Abstract

The invention relates to the field of gas separating technology, and especially relates to a method for replacing molecular sieves and aluminum oxide in a vertical type dual bed radial flow purifier. The method comprises the following steps: dismounting an outlet pipeline at the top of a cylindrical shell; hoisting a center cylinder out; dismounting a material filling port cover plate and dismounting a filling tube cap; extracting molecular sieves and aluminum oxide above a top surrounding strap; supplying air into the cylindrical shell for allowing air content in the cylindrical shell to reach the standard; setting a maintenance platform up in the cylindrical shell; dismounting manhole plates and an inspection cover at a top surrounding strap inspection hole; extracting molecular sieves and aluminum oxide between two grating interlayers; inspecting gratings; refilling molecular sieves and aluminum oxide between the two grating interlayers; reinstalling the inspection cover and the manhole plate; refilling molecular sieves and aluminum oxide above the top surrounding strap, and reinstalling the filling tube cap and the material filling port cover plate; dismounting the maintenance platform and cleaning the inner side of the cylindrical shell; reinstalling the center cylinder and the outlet pipeline. Replacing process of molecular sieves and aluminum oxide is simple and highly efficient.

Description

technical field [0001] The invention relates to the technical field of gas separation, in particular to a method for replacing molecular sieves and alumina in a vertical double-bed radial flow purifier. Background technique [0002] The vertical double-bed radial flow purifier is mainly used in the air purification stage in the field of air separation. It changes the traditional horizontal bed design method and makes the adsorption and analysis more reasonable and thorough. The vertical double-bed radial flow purifier consists of a cylinder, a central cylinder suspended inside the cylinder and a three-layer grid. The bottom of the three-layer grid is welded to the spherical head, and the top is suspended in the top shroud in the cylinder. . Activated alumina is installed in the interlayer between the outer grid and the middle grid, and molecular sieve is installed in the interlayer between the middle grid and the inner grid. There is a gas inlet at the bottom of the cylind...
