Explosive particle detection device and method

Abstract

The invention relates to a device and method for detecting explosive particles. Under the rotation of the output shaft of the motor, the air in the adsorption pipeline is directional flowed by the adsorption leaf fan, so that the explosive particles can be adsorbed along with the directional flow of the air. The switch is used to control the working circuit of the motor to control whether it works or not; the length of the leaf fan is consistent with the inner radius of the circular center of the adsorption pipe, which can make the internal air circulation more efficient; the water storage can help store water , where the generator is used to generate steam, and a valve is connected between the water storage and the generator to make the steam generate quantitatively; the whole semi-permeable membrane generating device is wrapped with insulating material, and the insulating material is wrapped with a heat-insulating film to prevent the user from Discomfort occurs and the safety of the present invention is improved; the backstab monitoring PC stores the results of the backstab detection, and can compare it with the transmitted diagram according to the original internal explosive peak-valley diagram.

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...

AI Technical Summary

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.
