Embodiment 1

[0031] A dangerous gas monitoring method using a radioactive tracer, comprising the steps of:

[0032] 1) Select water-insoluble radioactive substance solid micropowder as the tracer;

[0033] 2) The tracer is mixed and prepared with the dangerous gas;

[0034] 3) Determine the concentration of the leaked gas by the intensity of the radioactive material.

[0035] The invention mixes radioactive material solid micropowder with dangerous gas, controls the mixing ratio, and converts the leakage concentration according to the mixing ratio of dangerous gas and dangerous gas when the dangerous gas leaks, so that the data analysis and test are accurate, and the addition of radioactive material solid micropowder has no effect on dangerous gas. The fluidity of the liquid plays a role in reducing the floating height and diffusion speed of dangerous gases, and can be judged by the concentration of radioactive substances in the first time of leakage, providing a variety of ways to monito...

Embodiment 2

[0039] like Figure 1-5 As shown, the device for collecting solid micropowder gas containing radioactive substances includes a dust collector 4 connected to a collection pipe 5 at the inlet end, and a filter 3 connected to the outlet end of the dust collector 4, and the filter 3 is connected to the gas collection tank 2, and the gas The collection tank 2 is connected with a vacuum pump 1 . After the leakage of dangerous gas, it is not only necessary to monitor the leakage concentration to judge the degree of danger, but also to carry out emergency treatment on the leakage of dangerous gas to prevent major safety accidents. There are also certain safety hazards. When dealing with leaked gas, it is necessary to treat radioactive solid micropowder and dangerous gas together. In order to ensure the collection amount in the process of leaking dangerous gas, it is necessary to discharge the gas in the gas collection pipe 2 by using the vacuum pump 1. When the internal gas is exhaus...

Abstract

The invention discloses a dangerous gas monitoring method using a radioactive tracer, which comprises the following steps: 1) selecting water-insoluble radioactive substance solid micropowder as the tracer; 2) mixing and preparing the tracer with the dangerous gas; 3) The concentration of the leaking gas is determined by the intensity of the radioactive material. The present invention also provides a device for collecting solid micropowder gas containing radioactive substances. The method of the present invention determines the leaked gas concentration through a tracer, and the data analysis and test are accurate; the device of the present invention mainly solves the problem of gas leakage in the prior art. The dust filtration rate is not high and the gas outlet is easy to block.

Description

technical field [0001] The invention belongs to the technical field of gas monitoring, and in particular relates to a dangerous gas monitoring method using a radioactive tracer and a device for collecting solid micropowder gas containing radioactive substances. Background technique [0002] Rare gases, toxic gases and other gases have high requirements on the production environment during the storage process, especially in terms of safety. Once leakage occurs during the production process, it will bring serious consequences. Some toxic gases are harmful to the human body and the environment. It is very large; when these gases reach a certain concentration, it is difficult to detect them by human senses. When these gases reach a certain concentration, it is easy to cause safety accidents and personal injury. For example, the explosion limit of combustible gas in air is about 4%~75%, so if a large amount of combustible gas leaks, it will cause unimaginable consequences. [00...
