Problems solved by technology
During the water intake operation of nuclear power plants, marine organisms such as jellyfish and water hyacinth often block the circulating water flow channel, resulting in damage to the nuclear power plant unit, which will not only affect the operation safety of the nuclear power plant, but also cause great economic losses to the nuclear power plant

Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] It should be noted that when the circulating water does not pass through the drum filter 3 provided by the embodiment of the present invention, the circulating water is mixed with sundries of different sizes (the sundries include marine organisms such as jellyfish and water hyacinth).
[0021] The embodiment of the present invention provides a filter system, as attached figure 1 As shown, the filtration system includes: a mobile rake cleaning machine 1, a rotary cleaning machine 2, and a drum filter 3 arranged sequentially in the circulating water flow channel of the nuclear power plant along the flowing direction of the circulating water.
[0022] During the water intake operation of the nuclear power plant, the circulating wat...

The invention discloses a filtering system and belongs to the field of circulating water filtration. The filtering system comprises: a movable scraper bucket cleaning machine, a rotary cleaning machine and a drum filter net orderly arranged in a circulating water flowing path of a nuclear power plant along the flowing direction of the circulating water. Through use of the movable scraper bucket cleaning machine, the filtering effect on the large-sized debris is guaranteed. Through use of the rotary cleaning machine, the filtering effect on the medium-sized debris (such as marine organisms) isguaranteed. Through use of the drum filter net, the filtering effect on the small-sized debris (such as marine organisms) is guaranteed. The movable scraper bucket cleaning machine, the rotary cleaning machine and the drum filter net are orderly arranged in the circulating water flowing path so that the triple filtration of the sundries can be realized and the water intake operation safety of thenuclear power plant can be ensured.
Description
technical field [0001] The invention relates to the field of circulating water filtration, in particular to a filtration system. Background technique [0002] The circulating water system of nuclear power plants and the cooling water of important equipment use seawater as the water source, and the operation status of the water intake system directly affects the operation safety of nuclear power plants. During the water intake operation of nuclear power plants, marine organisms such as jellyfish and water hyacinth often block the circulating water flow channel, resulting in damage to the nuclear power plant unit, which will not only affect the operation safety of the nuclear power plant, but also cause great economic losses to the nuclear power plant . [0003] Therefore, it is very necessary to set up a filtration system in the circulating water channel upstream of the circulating water pump to filter marine organisms such as jellyfish and water hyacinth during the water in...
