Embodiment Construction

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper end", "lower end", "top", "bottom", "inner" and "outer" are based on the Orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention. Wherein, "upper end" and "lower end" are for the outside of the cold finger sampler 8, "top" and "bottom" are for the inside of the cold finger sampler 8, and "inside" and "outside" are For the internal space and the external space of the cold finger sampler 8, "water sample" is the moisture in the gas sample obtained after cold finger sampling, and the "gas sample" refers to the water that enters t...

Abstract

The invention relates to a gas cold finger sampling device which comprises a cold finger sampler, a cold finger inlet pipeline, a cold finger outlet pipeline and cooling equipment, the cold finger inlet pipeline and the cold finger outlet pipeline respectively extend into the cold sampler and are hermetically connected with the upper end of the cold sampler, the cold sampler can be inserted into the cooling equipment, and dry ice is arranged in the cooling equipment. According to the cold finger sampling device provided by the invention, dry ice is used as a cooling agent, so that the interference of the cooling agent in a measurement link on moisture in a gas sample is avoided, a good cooling effect is achieved, carbon dioxide gas of the gas sample is not condensed into solid to cause blockage, and meanwhile, the cold finger sampler is small in size and low in cost. The contact area with cooling equipment is large, and the condensation efficiency of moisture in a gas sample reaches 100%.

Description

technical field [0001] The invention belongs to the technical field of gas cold finger sampling, and in particular relates to a gas cold finger sampling device. Background technique [0002] The annulus gas system of the heavy water reactor needs to monitor the moisture content and its changes in the carbon dioxide gas in the system. The trace moisture in the gas is collected by condensation sampling, and the radioactivity and water quality indicators in it are analyzed to determine the source of moisture leakage and its leakage rate. [0003] The gas cold finger sampling device includes a cold finger sampler and a coolant. Immerse the cold finger sampler in liquid nitrogen, the gas enters the cold finger sampler, the moisture in the gas condenses into ice due to the cooling of the external liquid nitrogen, and condenses inside the cold finger sampler. After sampling, the ice condensed inside the cold finger sampler is melted into water, which can be taken out from the cold...
