Trace explosive and drug gas generation device and using method thereof

Abstract

The invention discloses a trace explosive and drug gas generation device and a using method thereof. The trace explosive and drug gas generation device comprises a device main casing, a heating device, a power source control device and a water bath temperature control tank, wherein a temperature regulator is arranged on the lateral face outside the device main casing, the heating device is arranged at the bottom of the device main casing, the power source control device is arranged on the lateral face outside the device main casing and used for controlling working of the heating device, the water bath temperature control tank is arranged in the device main casing, and at least one diffusion bottle is arranged in the water bath temperature control tank. The lateral wall of the water bath temperature control tank is provided with a temperature sensor, a water inlet communicated with an external water inlet pipe and a water drainage port which is sealed by a sealing device. The diffusion bottle can be composed of a bottle body and a bottle neck which are detachable, wherein a diffusion hole is arranged at the upper portion of the bottle neck. The trace explosive and drug gas generation device is simple in structure, convenient to use and capable of micro-heating the water bath temperature control tank and accurately controlling the temperature of the water bath temperature control tank, and effectively improves safety performance and gas distribution requirements when in use.

Description

technical field [0001] The invention relates to a gas generating device, in particular to a trace explosive and drug gas generating device and its application method. Background technique [0002] In recent years, various terrorist activities involving explosions have intensified, posing a major threat to international security and seriously affecting the peace and development of the world today. Based on the needs of the current anti-terrorism situation, governments of various countries have not only gradually adopted high-standard security measures, but also used Advanced safety inspection equipment has also invested a lot of money in the development of newer technologies and more advanced equipment; among them, the research and development of explosive detectors with gas sampling functions occupies a considerable proportion. In the actual work of anti-terrorism and explosion protection, gas Explosive detectors with sampling functions have also been used more and more. ...

Problems solved by technology

[0003] At present, many explosive detectors and drug detectors on sale have claimed that the detection sensitivity has reached the ppb level (10 -9 ) to ppt level (10 -12 ), individual explosive detectors based on trace gas detection technology have even claimed that the detection sensitivity has reached 10 -13 ~10 -15 ); however, it still needs to be verified whether the declared detection sensitivity has actually been achieved. Currently, explosive solutions with corresponding concentrations are generally used for confirmation. However, there is currently no scientific and reasonable method to verify the sensitivity index of explosive detectors that only have the function of gas sampling. Therefore, research and design a trace explosive gas configuration device, use the device to configure trace explosive gas with accurate concentration, carry out relevant tests on explosive detectors, objectively evaluate related explosive detection equipment, promote the continuous improvement of explosive detection performance, and help anti-terrorism explosion-proof work
