Explosive particle detection device and method

Abstract

The invention relates to an explosive particle detection device and a method. An adsorption leaf fan adsorbs the air in a adsorption pipeline for directional circulation under the rotation of the output shaft of a motor, so that the explosive particles can be adsorbed along with the directional flow of the air. A normally open switch is used for controlling a motor working circuit and controllingthe working thereof. The length of the leaf fan is consistent with the inner radius of a circular center of the adsorption pipeline, so that the air circulation efficiency in the leaf fan is higher. Awater storage device can help to store moisture. A production device is used for generating steam. A valve is connected between the water storage device and the production device, so that steam can be generated quantitatively. A whole semi-saturated film generating device is wrapped with an insulating material, and the insulating material is wrapped with a heat insulating film, so that discomforts of a user can be prevented, and the safety of the explosive particle detection device and the method is improved. A background monitoring PC stores the results of the back stimulation detection, andcan be compared with the transmitted graph according to the internal original explosive peak-to-valley map.

Description

technical field [0001] The invention relates to the detection of explosives through non-contact radioactive source technology, which is mainly used in the safety field of airports and railway stations, and in particular relates to an explosive particle detection device and method. Background technique [0002] With the advancement of science and technology and the substantial increase in people's income, it is normal for people to go out to travel and work, and with the rise of China's technology in transportation equipment, a large number of high-speed rails have been put into use. occasions, it is necessary to prevent some unscrupulous personnel from vandalizing. [0003] Peace and development have become the theme of today's world. However, terrorist attacks occur from time to time. Casualties and widespread panic caused by explosions are still the main attack methods used by terrorists. Due to the gene of nitro compounds such as RDX, PETN, TNG and TNT Its explosive part...

Problems solved by technology

[0004] The usual explosives detection method often collects the residual chemical components on the detected object by contact method to determine whether it carries or has been in contact with explosives. This method is often limited; at the same time, the detection process is complicated and the sensitivity is low. , it is inconvenient to carry, sometimes it cannot provide accurate detection information, the detection time is too long, etc.
