Problems solved by technology

[0002] Facilities involving tritium operations at home and abroad will produce a certain amount of tritium pollution. According to data research, tritium facilities are equipped with corresponding on-site tritium waste gas treatment devices or measures, but due to the conditions of tritium facilities or tritium operation sites, tritium process Processes, operating modes, operating hours, on-site tritium emission management limits, etc. vary, so there is no standard commodity sales in the market

Embodiment Construction

[0018] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific examples.

[0019] Such as figure 1 As shown, a purification device for processing tritium gas produced by a neutron imager includes a control and signal processing system, a gas delivery system, a gas collection system and a purification treatment system, and the control and signal processing system communicates with the control signal line The gas delivery system, the gas collection system are connected to the purification treatment system,

[0020] The gas delivery system includes a filter 1, a diaphragm booster pump 1 2 and a control valve 3. The filter communicates with the diaphragm booster pump 1 through a pipeline. A control valve is arranged between the collecting tank and the collecting tank;

[0021] The gas collection system includes two collection tanks 4 connected in series, a pressure gauge is a...

Abstract

A purification device for treating tritium gas generated by a neutron imager comprises a control and signal processing system, a gas conveying system, a gas collecting system and a purification treatment system. The control and signal processing system is connected with the gas conveying system, a gas collecting system and a purification treatment system through control signal lines; the gas conveying system comprises a filter, a diaphragm booster pump I and a control valve, the gas collecting system comprises two collecting tanks in series connection with each other, and the purification treatment system comprises a preheater, a palladium and platinum inorganic hydrophobic catalyst catalytic reactor, an air cooler, a condensation collector, a molecular sieve adsorber and an ammonia cooler. Qualified gas having passed an ionization chamber is discharged, and disqualified gas flows back to the collecting tanks through pipelines. Tritium gas purification is implemented efficiently and accurately through the device, the device has the advantages of less generated tritium waste, fewer refueling times and high stability and the like, and requirements such as site environments of a tritium process lab, emission limit and radioactive occupational health protection are met.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and nuclear equipment, and in particular relates to a system of a purification device for processing tritium gas generated by a neutron imager. Background technique [0002] Facilities involving tritium operations at home and abroad will produce a certain amount of tritium pollution. According to data research, tritium facilities are equipped with corresponding on-site tritium waste gas treatment devices or measures, but due to the conditions of tritium facilities or tritium operation sites, tritium process Processes, operating modes, operating hours, on-site tritium emission management limits, etc. vary, so there is no standard product on the market. Because tritium gas is at normal temperature, normal pressure, and normal humidity, half of HT will be converted into HTO in about 60 days, and the inhalation hazard of HTO is 1.0×10 of gaseous tritium. 4 times, HTO can also be absorbed in...
