Embodiment Construction

[0025] The mobile air filter sodium flame test system is designed in accordance with the requirements of "High Efficiency Air Filter Performance Test Method Efficiency and Resistance" (GB / T 6165), and is used to test the efficiency and resistance of air filters. The system includes a detection platform, a fogging device (spray box), a hydrogen generator, an aerosol and a detection device, an air duct system, and a compressed air supply system. All the above equipment components are installed in the 40GP container, which makes the testing equipment intensive, miniaturized and easy to transfer, and can realize the testing of air filters in multiple nuclear power plants. A temperature-controlled exhaust system is installed in the container to keep the operating environment in a normal temperature and humidity environment to ensure the accuracy of the detection.

Abstract

The invention belongs to the field of nuclear detection, and particularly relates to a sodium flame method detection system. At present, a large number of various ventilation filters need to be replaced every year in a nuclear power plant, and large radioactive technical waste is generated. The device comprises a fogging device, an air duct system, a compressed air supply system, a sampling deviceand a detection device, wherein the fogging device comprises an atomizing box, and the atomizing box is connected with the air duct system, The device is intensive, miniaturized and easy to circulate, and can detect the air filter in a plurality of nuclear power stations. A temperature control exhaust system is arranged in the container, so that the operating environment is kept in a normal-temperature and normal-humidity environment, and the detection accuracy is ensured.

Description

technical field [0001] The invention belongs to the field of nuclear detection, and in particular relates to a sodium flame method detection system. Background technique [0002] During the operation of nuclear power units, in order to ensure that the radioactive substances in the control area do not leak into the environment, the radiation control area is equipped with a special ventilation system and air filtration device to purify and retain radioactive particles in the air. Therefore, a large number of various ventilation filters need to be replaced every year, resulting in a large amount of radioactive technical waste. [0003] In order to reduce the amount of radioactive waste and reduce costs and increase efficiency, the company's waste minimization leading group organized and carried out a special research and development work on "reuse of nuclear-grade high-efficiency air filter metal frames". After the "metal frame reusable" filter reaches the end of its service l...
