Novel complete device for room-temperature delay treatment of highly radioactive waste gas of nuclear power station

Abstract

The invention relates to a novel complete device for room-temperature delay treatment of highly radioactive waste gas of a nuclear power station, which is characterized by mainly comprising a buffer tank (1), a pre-filter (2), a dryer (3), a heater (4), a protective bed (5) filled with activated carbon and at least two delay beds (6 and 7) connected in series. The gas inlet end of the buffer tank (1) is connected with the output end of a tank for waste gas collection through a pipeline, the output end of the buffer tank (1) is connected with the input end of the pre-filter (2), the output end of the pre-filter (2) is connected with the input end of the dryer (3), the output end of the dryer (3) is connected with the input end of the heater (4), the output end of the heater (4) is connected with the input end of the protective bed (5), the output end of the protective bed (5) is connected with the input end of the delay bed (6), the output end of the delay bed (7) is connected with the input end of an efficient particulate filter (8) through a pipeline, and the output end of the efficient particulate filter (8) is connected with the corresponding input end of a plant ventilation system (9). The device has a simple structure, the area and energy can be saved, the cost of operation and maintenance is low, and the device is safe and reliable.

Description

technical field [0001] The invention relates to nuclear power plant equipment, in particular to nuclear power plant exhaust gas treatment equipment, in particular to a new type of nuclear power plant high-level radioactive waste gas normal temperature delay treatment complete set. Background technique [0002] As we all know, my country's nuclear power industry has gone through more than 20 years of development. At present, the nuclear power plants that have entered commercial operation mainly include: Qinshan Phase I, Phase II, and Phase III, Daya Bay, Ling Ao Phase I, Phase II and Hetian Bay Nuclear Power Plant. The total amount accounts for 1.9% of the country's total power generation, while the global average nuclear power has accounted for 16% of the total power generation, of which the proportion of nuclear power in the United States, Japan, and France has reached 20%, 30%, and 80% respectively. There is still a big gap between my country's nuclear power and the wor...
