Abstract

The invention relates to the technical field of nuclear power station waste liquid treatment systems, and relates to nuclear power station radioactive wastewater filtering equipment and a control device thereof. An alternating current input side of a switch power supply in the control device is connected with a power supply circuit, a direct current output side of the switch power supply is connected with a normally-closed switch assembly, wherein the normally-closed switch assembly is connected with a normally-open switch assembly, the normally-open switch assembly is connected with a controlswitch assembly, and the control switch assembly is connected with a direct-current output side of the switch power supply; the power supply circuit is connected with an electric pump in the filtering equipment through the control switch assembly, the control switch assembly is electrified when the normally-closed switch assembly and the normally-open switch assembly are in a conducting state, and when the control switch assembly is electrified, the voltage output by the power supply circuit is connected to an electric pump. The electric pump is additionally arranged on the filtering equipment, the electric pump is electrically controlled by adopting the control device, working personnel can conveniently control the starting and stopping of the filtering equipment, and the influence of the nuclear radiation, caused when the radioactive wastewater in the nuclear power station is filtered, is reduced.

Description

technical field [0001] The application relates to the technical field of nuclear power plant waste liquid treatment systems, in particular to a nuclear power plant radioactive waste water filtering equipment and a control device thereof. Background technique [0002] With the increasing energy consumption, the construction of nuclear power plants has entered a peak period. However, during the construction and use of nuclear power plants, it is necessary to strengthen the safety supervision of nuclear facilities and radioactive sources to ensure the safety of nuclear pollution and radiation environments. The radioactive waste water in the fuel pool of the existing nuclear power plant needs to be purified and treated by filtering equipment before it can be discharged, so as to prevent the waste water from being discharged directly to produce nuclear radiation or nuclear pollution. [0003] In the process of wastewater treatment in the early stage, a filter device is required t...
