Embodiment Construction

[0009] Such as Figure 1~3 As shown, the present invention is a flushing system of a nuclear power plant drum-type rotary filter screen. The top of the drum-shaped rotary filter screen 6 is a flushing system. The flushing system is fixed on the fixed bracket by two flushing pipes 1 through fastening bolts 2. 7, the length of the flushing pipe 1 is about 200mm longer than the length of the drum-type rotary screen 6, and the flushing pipe 1 is connected with the water inlet pipe through the connecting flange 3, and the flushing pipe is provided with a plurality of connecting nuts 5. Nozzle 4, the shape of the outlet of the nozzle 4 is rectangular, and directly below the flushing pipe 1 is a garbage collection device 8. When the drum-shaped rotary filter screen 6 is in normal operation, it will be on the inner surface of the filter plate of the drum-shaped rotary filter screen 6. There is a lot of garbage attached. When passing through the flushing system, the high-pressure water...

Abstract

The invention aims to provide a shower nozzle for a flushing system of a drum-shaped rotating filter net of a nuclear power plant, which can effectively solve the problems that flushing dead zones can be formed in a local area which can not be flushed by flushing water or the flushing water pressure is insufficient in the prior art, thus a filter plate can be blocked due to accumulation of sundries in a long time by changing the outlet shape of the shower nozzle, thereby improving the flushing capability.

Description

technical field [0001] The invention relates to a flushing system for a drum-type rotary filter screen used in a filter system of a nuclear power plant. Background technique [0002] At present, the nozzles of the flushing system of the drum-shaped rotary screen used in nuclear power plants are all circular in shape, and the flushing effect is not ideal. In some areas, the flushing dead zone is formed due to insufficient flushing water or insufficient flushing water pressure, which will last a long time. The accumulation of debris over time will cause the blockage of the filter plate, which seriously affects the normal operation of the filter system of the nuclear power plant. Contents of the invention [0003] In order to solve the above problems, the task of the present invention is to provide a nozzle for the flushing system of a nuclear power plant drum type rotary screen, which solves the problem of flushing caused by insufficient flushing water or insufficient flushi...
