In hot summer, in addition to traditional risks such as flammability, explosion and volatility, hazardous chemical enterprises also have to accept environmental tests such as high temperature, long sunshine time, high intensity, many thunderstorms and long flood season. According to incomplete data statistics, in the past 30 years, there have been as many as 18 major accidents of hazardous chemicals in China from July to September, accounting for more than 40% of the total. Therefore, hazardous chemical enterprises should strictly prevent the prone and frequent periods of accidents in summer, and achieve advanced prevention and hidden danger management.

1. Risk of over temperature and over pressure

In high temperature in summer, some hazardous chemicals volatilize quickly, and at the same time, it is very easy to cause pressure rise due to the temperature rise of gas and liquid. The pressure of storage facilities, transmission pipelines, valves and flanges increases, and the possibility of leakage and explosion of hazardous chemicals is greatly increased.

2. Chemical reaction risk

It is rainy and humid in summer, and dangerous chemicals that avoid water are prone to violent chemical reactions when encountering water in summer, releasing heat and generating flammable gases, increasing the risk of combustion, explosion or release of toxic substances.

3. Risk of cross interference

In summer flood season, the traditional gas leakage detector should be affected by the complex environment such as high humidity and water vapor, resulting in false alarm and missing alarm. Even unable to work in case of flooding.

Therefore, in the face of complex and changeable weather factors in summer, hazardous chemical enterprises should regularly detect key equipment and maintain an emergency state at all times. At the same time, an all-round, three-dimensional and blind zone free dynamic monitoring and online monitoring system is established to collect combustible and toxic gas alarm data and videos of key parts in real time, so as to realize the global supervision of hazardous chemicals.

Hanhai technology group, in cooperation with the Chinese Academy of Sciences, has undertaken the industrialization of laser absorption spectroscopy gas detection technology, a major national special scientific research achievement. Aiming at the current safety situation of hazardous chemical enterprises, the self-developed laser monitoring series products overcome the technical bottleneck of integrating the characteristics of water flooding resistance, corrosion resistance, high precision, long life and calibration free, and effectively solve the technical problems of sensor measurement drift, weak monitoring environment transmission signal and long-term low-power operation.

Fixed reflection laser gas telemeter

The fixed reflection laser gas telemeter is composed of a laser control unit, a spectral analysis unit and an optical reflection unit.

04. Strong anti-interference

Compared with traditional detectors, which are easily disturbed by environment, cross gas and other factors, the anti-interference ability is strong. Fingerprint detection, truly achieve zero false positives.

05. More stable

The traditional detection equipment has poor stability and is vulnerable to impact and poisoning caused by excessive concentration of flammable, toxic and harmful gas leakage; Then detect the failure. Passive fiber laser leakage monitoring equipment does not have this problem. The working performance is more stable.

06. Precise measurement

Through the spectral inversion algorithm, the leakage gas concentration value can be quickly obtained, and the sensitivity is as high as 1ppm. M, which completely eliminates the phenomenon of false alarm and false alarm.

07. "0" maintenance

There is no need to adjust the product, which can save operation in the whole life cycle

Cost.

08. Long service life

The service life of the product is up to 20 years.

09. Detection of gas diversification

It has the ability to detect methane, carbon monoxide, carbon dioxide, hydrogen sulfide, ethylene, acetylene, ammonia and other gases (more gas detection schemes can be provided according to customer needs).

Fixed scanning laser gas telemeter

The fixed scanning laser gas telemetry instrument can monitor the gas concentration with 360 degree rotation scanning of radar within a radius of 300 meters. It can monitor the gas concentration in real time, and conduct remote online visual intelligent monitoring in the way of data combined with high-definition video, so as to locate the leakage direction. It is suitable for operation scenarios with complex process layout and high risk, which need to realize large-scale monitoring.
