Problems solved by technology

[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; before 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

Embodiment 1

[0025] Such as Figure 1-5As shown, a dangerous gas monitoring device using a fluorescent tracer includes a gas monitoring module, a control module and a gas processing module, and the gas monitoring module: includes a drone 1, and the drone 1 is equipped with a wireless transmission device 2, UAV controller 3, wind direction and anemometer 4, video camera 5, gas sensor 8 is provided under the fuselage of UAV 1; Control module: comprises the mobile terminal 11 that is connected with signal transceiver 10; UAV 1 body A clamp 7 for connecting the suction pipe 12 is provided on the side, and the suction pipe 12 is connected with the gas processing module. In the present invention, after the fluorescent solid micropowder is mixed with the dangerous gas, the fluorescence intensity emitted by the fluorescent solid micropowder after the dangerous gas leaks can directly display the gas leakage concentration, so that the naked eye can distinguish the gas leakage concentration. When the...

Embodiment 2

[0033] The suction pipe 12 of the present invention is prepared by the following process:

[0034] 1) Select the aluminum composite pipe as the raw material, after continuous multi-stage stamping and stretching, the pipe body is bent with a bending angle of 120°, and the port 24 of the bending section is reamed to form a gradually expanding pipe 26 with a diffusion angle of 15° °;

[0035] 2) Weld the diffuser plate 28 corresponding to the inner diameter of the expander tube 26 with the inner wall of the expander tube 26, the angle between the diffuser plate 28 and the inner wall of the expander tube 26 is 12°, and weld the mesh plate 27 to the expander tube 26 Nozzle;

[0036] 3) Heat the formed suction pipe 12 to 710°C±5°C, treat at constant temperature for 25-30min, carbonitride, nitrogen source is ammonia, carbon source is methane, and the carbon potential in the strong infiltration stage is controlled to 1.26±0.05 %, the flow rate of ammonia gas is 1.9-2.6L / min, the flo...

Embodiment 3

[0040] A dangerous gas monitoring method using a fluorescent tracer, comprising the following steps:

[0041] 1) Select fluorescent solid micropowder as the tracer;

[0042] 2) The tracer is mixed with dangerous gas, prepared and packed;

[0043] 3) Measure the concentration of leaked gas by fluorescence intensity or gas sensor 8 .

[0044] The existing equipment in the device of the present invention should be known to those skilled in the art, and it can be obtained by market purchase, for example, fluorescent solid micropowder is phosphor powder, and fluorescence detector 6 is the product that can be used for detecting fluorescence concentration for market purchase, such as Shenzhen The model produced by City Tianmeiyi Technology Co., Ltd. is WP1213 VSON fluorescent agent detection pen; the SPM deodorization equipment used in the present invention is the SPM-series malodorous gas TiO2 photocatalytic oxidation equipment produced by Shenzhen Xinshengda Environmental Protecti...
