Problems solved by technology

In order to cope with frequent cold source incidents, each power station in operation generally arranges some temporary interception facilities in the water intake channel. These temporary facilities are patch-type improvements with poor mechanization and require a lot of manpower. Damaged, not included in the formal system for operation and maintenance management
[0003] The existing circulating water filtration system and temporary measures can no longer meet the needs of stable operation of the power station. Therefore, an automatic lifting and suction device is needed to reduce the frequency of retracting and releasing the net, effectively deal with sudden outbreaks of marine organisms, and ensure the stable operation of nuclear power units.

Abstract

The invention relates to an automatic lifting suction device which comprises a frame, a suction pump is arranged below the frame, a water inlet pipe and a water outlet pipe are installed on the suction pump, and a trap is installed at the end, away from the suction pump, of the water inlet pipe; according to the automatic lifting suction device, by additionally arranging the automatic lifting suction device, the frequency of collecting and releasing a net can be reduced, sudden outbreak marine organisms can be effectively dealt with, stable operation of a nuclear power unit is guaranteed, impurities on the sea level can be blown, the impurities can be prevented from influencing the detection precision of an ultrasonic liquid level, and therefore the reliability of seawater suction is improved, and the service life of the nuclear power unit is prolonged. And meanwhile, additional self-cleaning can be realized, and the filter screen is prevented from being blocked.

Description

technical field [0001] The invention relates to an automatic lifting suction device, which belongs to the field of nuclear power plant circulating water cooling. Background technique [0002] my country's coastal nuclear power plants use seawater as a cold source to provide cooling water for steam turbines and nuclear island equipment. In recent years, with the change of the sea environment, nuclear power plant outages caused by the invasion of marine organisms or marine debris have occurred from time to time. In order to cope with frequent cold source incidents, each power station in operation generally arranges some temporary interception facilities in the water intake channel. These temporary facilities are patch-type improvements with poor mechanization and require a lot of manpower. Damaged, not included in the formal system for operation and maintenance management. [0003] The existing circulating water filtration system and temporary measures can no longer meet the...
