Description

technical field [0001] The invention relates to the technical field of gas purification equipment, in particular to a medical oxygen purification device that is convenient for cleaning the inner wall of a pipeline. Background technique [0002] Gas purification refers to the filtration and adsorption treatment of gas to achieve the purpose of purifying and drying the gas and reducing the impurity content. It can also be used for deep drying of cylinder gases such as hydrogen, nitrogen, oxygen and compressed air, and pipelines will be used in the use of gas purification devices To transport it, some of the existing gas purification pipelines on the market transport part of the gas with high density and heavy weight, and the impurities will be precipitated and adsorbed under the inner wall of the pipeline, but some existing gas purification pipelines on the market lack protection against the inner wall. The cleaning structure will lead to the accumulation of residues, resultin...

Problems solved by technology

[0002] Gas purification refers to the filtration and adsorption treatment of gas to achieve the purpose of purifying and drying the gas and reducing the impurity content. It can also be used for deep drying of cylinder gases such as hydrogen, nitrogen, oxygen and compressed air, and pipelines will be used in the use of gas purification devices To transport it, some of the existing gas purification pipelines on the market transport part of the gas with high density and heavy weight, and the impurities will be precipitated and adsorbed under the inner wall of the pipeline, but some existing gas purification pipelines on the market lack protection against the inner wall. The cleaning structure will lead to the accumulation of residues, resulting in a decrease in the purity of the gas to be transported and causing peculiar smells on the inner wall of the pipeline. For this reason, we propose a medical oxygen purification device that is convenient for cleaning the inner wall of the pipeline to solve the above problems
