Problems solved by technology

[0002] In the field of petrochemical industry, the adsorbent is leaked from the early bed of the adsorption tower. When the adsorption tower is replaced, the adsorbent will be taken out during the stripping step and brought into the compressor, causing damage to the compressor and making it impossible to continue the stripping operation.

Abstract

The invention relates to a technology for filtering an adsorbent during stripping of an adsorption tower of a bed leakage agent, in particular to an adsorption tower steam stripping improved structureof bed leakage agent, which comprises an extracting solution system, a raffinate system and a stripping line, wherein the extracting solution system and the raffinate system are connected through a pipeline and are jointly connected to a stripping line, the stripping line is connected to a compressor, an outlet lower line of the extracting solution system is connected with the stripping line through a first pipeline, an outlet lower line of the raffinate system is connected to the first pipeline through a second pipeline and is connected with the stripping line through the first pipeline, after improvement, when the adsorbent is replaced in the adsorption tower, the adsorbent is prevented from being brought into the compressor to damage the compressor in the steam stripping step, and smooth steam stripping operation is guaranteed.

Description

technical field [0001] The invention relates to the technology of filtering the adsorbent during the stripping of the adsorption tower of the leakage agent of the bed layer, in particular to the improved structure of the stripping of the adsorption tower of the leakage agent of the bed layer, and belongs to the field of petrochemical industry. Background technique [0002] In the field of petrochemical industry, the adsorbent leaks from the early bed of the adsorption tower. When the adsorption tower is replaced, the adsorbent will be taken out during the stripping step and brought into the compressor, causing damage to the compressor and making it impossible to continue the stripping operation. Contents of the invention [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to provide an improved stripping structure of the adsorption tower of the leakage agent in the bed. After the improvement, when the adsorption tower is chang...
