Abstract

The invention provides an online cleaning device for a methanol washing methanol filter. The online cleaning device for the methanol washing methanol filter comprises a methanol filter; a high methanol washing input end which is arranged at the input end of the methanol filter; a medium methanol washing output end which is arranged at the output end of the top of the methanol filter; and a cleaning pipeline inlet which is formed in a cleaning input port in the top of the methanol filter. According to the online cleaning device for the methanol washing methanol filter, the online cleaning device is provided with a hot desalted water input end pipe and a steam pipeline, the hot desalted water input port and the steam input port are respectively adopted to enter the inlet of the cleaning pipeline and the interior of the methanol filter for filtering so that the interior of the methanol filter is conveniently cleaned again through steam, the purpose of multi-medium cleaning is achieved, and the problem of incomplete cleaning is solved by adopting multiple media and multiple cleaning methods.

Description

technical field [0001] The invention relates to the technical field of cleaning methanol washing filters, in particular to an online cleaning device for methanol washing methanol filters. Background technique [0002] Low-temperature methanol washing, using cold methanol as the absorption solvent, using the excellent characteristics of methanol’s great solubility to acid gases at low temperatures, to remove acid gases in the raw material gas, the process generally includes an absorption tower and multiple desorption towers, the absorption tower absorbs Acid gas, the analysis tower resolves the acid gas and returns the lean liquid methanol to the absorption tower to achieve the recycling of methanol. When methanol is used for washing, it is necessary to use methanol to wash the filter. [0003] The methanol washing filter has a large pressure difference. When it needs to be switched and cleaned, the online cleaning effect is often poor and the cleaning is not thorough. After ...
