Abstract

The invention discloses a radioactive waste incineration flue gas filtering method, and aims to solve the problem that ash removal and filter bag replacement of a bag filter used in the field of radioactive waste incineration at present in China need to be operated in an open manner. A bag filter used in the method comprises a box body, a partition plate assembly, filtering units and an ash removal unit, the partition plate assembly is arranged in the box body, at least two dust filtering chambers are formed between the partition plate assembly and the inner wall of the box body, and at leasttwo filtering units are arranged. The inventor of the invention makes a brand new improvement on the structure of the filter; the bag type filter can realize simple and closed operation of dust removal and filter bag replacement of the filter, effectively solves the problem that dust removal and filter bag replacement of a conventional bag type filter need to be opened, reduces the labor intensityand occupational injury of operators when the bag type filter is used for operation in the field of radioactive waste incineration, and ensures occupational health of the operators. Based on the improvement of the inventor, the problem of difficulty in ash removal of the filter is solved, and the application value is higher.

Description

technical field [0001] The invention relates to the field of incineration flue gas dust removal, especially the field of radioactive waste incineration, and specifically relates to a method for filtering radioactive waste incineration flue gas. This application provides a bag filter, which can realize functions such as automatic airtight ash removal, airtight replacement of filter bags, and free switching of filter chambers, reducing the risk of personnel exposure or inhalation of harmful dust during ash removal and filter bag replacement, and ensuring operation Occupational health of personnel has high application value and good application prospects. Background technique [0002] In the field of waste incineration, the incineration flue gas needs to be treated before it can be discharged. Among them, a key step in the treatment of incineration flue gas is to use a bag filter to initially filter the dust in the flue gas; during this process, the dust is intercepted by the ...
