Problems solved by technology

According to the decommissioning experience of nuclear facilities for many years, the insoluble solid particles in the radioactive waste liquid produced during the decommissioning process have brought many problems to the three waste treatment facilities: deposition at the bottom of the storage tank, clogging of pipelines, scratching of transfer pump blades, clogging of instrument pipes, clogging of sampling Tubes, reducing evaporator efficiency, increasing the number of solidified bodies, scratching the blades of the stirring paddles, etc., these derivative problems have caused the overall high radiation level of the three wastes treatment facilities, which in turn increased the exposure dose of the maintenance staff
Under this condition, if the filter water inlet is set at the top of the filter, it will cause the filter to be unable to be installed and disassembled, so the filter inlet can only be set at the bottom, and personnel cannot use flanges and seals in the middle tank. The sealing method combined with ring and bolt can reliably seal the filter inlet and pump outlet pipe, so it is necessary to study an installation method that can achieve precise positioning of the filter and reliable sealing when the worker operates above the heavy concrete

Embodiment Construction

[0024]In order to be able to understand the above objectives, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other if they do not conflict with each other.

[0025]In the following description, many specific details are explained in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from the scope described here. Therefore, the protection scope of the present invention is not disclosed below. Limitations of specific embodiments.

[0026]Please refer toFigure 1-Figure 2, The present invention changes the filter inlet from the top to the bottom, the filter is installed upside down to the middle water tank, at the same time, the filter is a...

Abstract

The invention discloses a radioactive liquid filtering device and a filter replacement method, and belongs to the fields of treatment of three waste and nuclear radiation protection. The device comprises a middle water tank, a filter, a filter inlet female connector, a filter support, a filter support male connector, sealing rings, a plurality of guiding supports, an inlet pipe and a heavy concrete layer. By means of the method, long-distance installation of the filter can be achieved, people do not need to get close for installation, the installation speed is much higher than those of universal installation modes of flanges, gaskets and bolts, a sealing effect of a filter inlet can also meet the use requirements, exposure doses of people can be reduced greatly, and the safety of people isprotected.

Description

Technical field[0001]The present invention relates to the field of radioactive liquid processing in the nuclear field, in particular to a radioactive liquid filtering device and a filter replacement method.Background technique[0002]The radioactive waste liquid generated during the decommissioning or overhaul of nuclear facilities can be classified into primary circuit waste water, decontamination waste liquid, boron-containing waste liquid, and storage pool waste liquid. These waste liquids all contain radioactive insoluble solid particles. Among them, the concentration of radioactive insoluble particles contained in decontamination waste liquid and storage pool waste liquid is the highest. Based on many years of experience in nuclear facility decommissioning, the insoluble solid particles in the radioactive waste liquid generated during the decommissioning process have caused many problems for the three waste treatment facilities: deposits at the bottom of the tank, blocked pipelin...
