The self-suction-type Venturi water scrubber performance testing system comprises a self-suction-type Venturi water scrubber and a data collecting system, and is characterized in that the self-suction-type Venturi water scrubber performance testing system further comprises an air supply loop, a steam supply loop, a gas mixed distribution loop, an inlet sampling section, a self-suction-type Venturi water scrubber injection property measuring loop and an outlet sampling section; after being joined, an outlet of the air supply loop and an outlet of the steam supply loop are connected with an inlet of the gas mixed distribution loop, an outlet of the gas mixed distribution loop is connected with the inlet sampling section, an outlet of the inlet sampling section is connected with the self-suction-type Venturi water scrubber, and the self-suction-type Venturi water scrubber is externally connected with the injection property measuring loop.

Description

technical field [0001] The invention relates to a performance experiment system of a self-priming venturi water washer. Background technique [0002] When a severe reactor core melt accident occurs, a large amount of radioactive substances will be released into the containment, causing the pressure inside the containment to rise. The method is to wash and filter the gas in the containment and discharge it into the environment, so as to prevent the overpressure of the containment and reduce the release of radioactive substances into the environment as much as possible. The safety of the next nuclear power plant is of paramount importance. [0003] Due to the advantages of simple structure and high filtration efficiency, Venturi water scrubber has gradually attracted people's attention in the design of containment filtration and discharge system of nuclear power plants in recent years, and has been applied to a certain extent. However, due to the passive safety requirements ...

AI Technical Summary

Problems solved by technology

Due to the special nature of nuclear power, when a serious accident occurs in a nuclear power plant, the release of a large amount of radioactive substances will threaten the living environment of human beings. Therefore, in the event of a serious accident, the filtration efficiency of radioactive substances in the discharge system becomes the verification system reliability and safety. so that any set of Venturi scrubbers or other filtering devices applied to the containment filtration and drainage system must pass strict tests, but the reliability of the equipment cannot be tested in actual severe accidents, for Therefore, a system that can simulate the high-temperature, high-pressure, and high-humidity atmospheric environment in the containment under various accident conditions is needed. This system is used to test the performance of the self-priming Venturi scrubber. At present, there is no published literature at home and abroad. Mention of experimental systems that can be used to test the performance of self-priming venturi scrubbers
