Channel type explosive /drug checking door

Abstract

The invention discloses a channel type explosive / drugs detecting gate, comprising a channel doorframe, wherein, a gas jet orifice which is arranged on the channel doorframe and jets gas upwards, a sample collecting device which is arranged on the upper part of the doorframe, and a detector which is arranged on the rear of the sample collecting device, wherein, the sampling collecting device is a device which separates particles of a detected substance in the gas, vaporizes and sends into the detector. The invention has a reasonable structure, a non-contact mode, short sampling period and highefficiency, thereby guaranteeing that the channel type explosive / drugs detecting gate has the advantages of quick detection speed, high sensitivity and so on.

Description

Channel Explosives / Narcotics Detection Door Technical field: The invention relates to a detection device. Background technique: With the increasing exchanges and frequent exchanges between our country and the international community, the incidents of domestic and foreign criminals carrying out criminal activities through the customs are also increasing. In particular, international drug trafficking and terrorist bombings pose a serious threat to national security and social stability. Airports, stations, etc. Ports, docks, government departments and public safety areas have become important places for criminals to carry out illegal activities. Due to the large flow of people in the above places, the detection capacity of conventional equipment is difficult to meet, and there is an urgent need for a fast drug / explosives detector. Due to the large molecular weight of explosives / drugs, they are easily adsorbed on the surface of tiny particles (such as dust, clothing fibers,...

AI Technical Summary

Problems solved by technology

Conventional sampling transfers the tiny particles on the subject to the sampling paper by wiping, and then analyzes the sampling paper. Although the detection success rate is high, the analysis process is complicated and time-consuming, which cannot meet the needs of large-traffic locations. at the same time, the analysis process uses contact sampling, and the tested personnel are usually unwilling to accept
