Waste liquor sampling device

Abstract

The invention belongs to the technical field of analysis and treatment of radioactive waste, and discloses a waste liquor sampling device. The device comprises a carrying and moving mechanism, an operation panel, a vacuum pump, a sampling tank and a buffer tank, wherein the operation panel, the vacuum pump, the sampling tank and the buffer tank are all fixed on the carrying and moving mechanism; the sampling tank is positioned under the buffer tank and is connected with the buffer tank through a pipeline; the vacuum pump is connected with the top of the buffer tank through a pipeline to pump negative pressure of the buffer tank and the sampling tank so as to enable waste liquor to get into the sampling tank from a waste liquor storage tank. The device has the advantages that the movement is convenient, the sampling is simple, and the quantitative sampling is realized.

Description

technical field [0001] The invention belongs to the technical field of radioactive waste analysis and disposal, and in particular relates to a waste liquid sampling device. Background technique [0002] With the continuous development of my country's nuclear industry, the daily operation and maintenance and emergency treatment of various nuclear facilities continue to produce radioactive waste liquid, and more and more old facilities are facing closure and decommissioning. The investigation and detection of radioactive waste liquid sources is a prerequisite for waste liquid treatment, which runs through the entire process of nuclear facility shutdown and decommissioning, and is also the guarantee for safe and rapid handling of nuclear facility emergency events. In the process of source item investigation, sampling and analysis of newly generated and possible radioactive waste liquid in nuclear facilities is an indispensable work. [0003] At present, many nuclear facilitie...

AI Technical Summary

Problems solved by technology

[0003] At present, many nuclear facilities facing decommissioning are old. There is no sampling system in the facility or the original sampling system is polluted or damaged. Sampling is difficult. The sampling method for such nuclear facilities and radioactive waste liquid in response to nuclear emergency is generally artificial direct sampling

This method has the following two disadvantages. First, it is inconvenient to operate. It requires personnel to visit the top of the waste liquid storage tank or the pit to pass through the manhole on the equipment or sink into the sampling bottle from the mouth of the pit to take samples. Accidents are prone to occur and each sampling requires at least Two staff members cooperate and the operation takes a long time

Secondly, personnel must stay in areas with strong radioactivity for a long time, which will inevitably cause radiation hazards or other contamination to the human body.
