Abstract

The invention discloses a method for filtering flue gas from radioactive waste incineration, aiming to solve the problem that bag filters currently used in the field of radioactive waste incineration in China need to be opened for ash removal and filter bag replacement. The bag filter used in this method comprises a box body, a partition assembly, a filter unit, and an ash removal unit; There are at least two filter units respectively. The inventor of the present application has carried out a new improvement on the structure of the filter, which can realize the simple and airtight process of filter ash removal and filter bag replacement, effectively solve the difficult problem of conventional bag filter ash removal and filter bag replacement that need to be opened, and alleviate When the bag filter is used in the field of radioactive waste incineration, the labor intensity and occupational damage of the operator should be guaranteed to ensure their occupational health. Based on the inventor's improvement, the present application solves the problem of difficulty in filter ash removal, and has high application value.

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 ...
