It's the annual festival full of love

However, the feelings of lovers are like dangerous chemicals in this hot summer

"Flammable", "explosive", "Volatile"

Talking about dangerous chemicals in summer

We have to say that the next hazardous chemical enterprise

Safety issues that should be paid attention to in summer

(1) risk of overtemperature and overpressure

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

(2) chemical reaction risk

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

(3) cross interference risk

In the 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. And even unable to work in case of flooding.

Facing the complicated and changeable weather factors in summer

Hazardous chemical enterprises shall regularly test key equipment

Establish an all-round, three-dimensional and blind area free online monitoring system

Real time collection of combustible and toxic gas alarm data

And videos of key parts

Realize global supervision of hazardous chemicals

Hanhai technology group and Hefei Institute of Materia Medica of Chinese Academy of sciences have undertaken the industrialization of the national major special scientific research achievement laser absorption spectrum gas detection technology. In view of the safety status of hazardous chemicals enterprises, the laser monitoring series products independently developed have overcome the technical bottleneck of integrating water flooding resistance, corrosion resistance, high accuracy, long life and calibration free characteristics, and effectively solved the technical problems of sensor measurement drift, weak transmission signal in monitoring environment and long-term low power consumption operation.

Passive optical fiber laser leakage monitoring system

The passive optical fiber laser leakage monitoring system is composed of a system host (laser control unit, spectrum analysis unit), a light sensing terminal and a monitoring platform. The laser absorption spectrum gas detection technology (TDLAS) is used to connect the light sensing terminal installed on the monitoring site with the host of the monitoring center system through optical fibers. Multiple light sensing terminals can be installed in the monitoring area, which can work for a long time without power supply on site, and realize multi-point, real-time and uninterrupted remote monitoring of gas concentration. The corresponding light sensing terminal or detector can be matched according to the application requirements of the scene. The system supports 8, 16, 32, 64, 128, 254 multi-channel customization, covers the three-dimensional space above and below the ground, and provides users with solutions for safety detection products.

01 、there is no need for power supply on site, and the system is safer

The monitoring site does not need power supply and is connected through optical fiber. The monitoring platform receives and processes the information of each light sensing terminal on the site in real time, and the monitoring is more stable.

02 、easy installation and more flexible configuration

It subverts the traditional system composition mode and adopts the digital design from the light sensing terminal to the control system. The simplified system structure makes installation easier and can meet more application needs of customers.

03、 no need to replace the detection element

The light sensing terminal is a pure optical device with no loss characteristics. High reliability, no adjustment required.

04 、preventive monitoring

The response time of each monitoring channel is only 10 seconds, and the transmission distance can reach 20 kilometers. It can accurately detect ppm level trace gas leakage and truly realize the preventive monitoring of gas leakage.

05、 perfect alternative to traditional catalytic combustion alarm system

Super long operating life of the whole system. Greatly reduce the equipment operation cost throughout the life cycle, once and for all.

06、 detection gas diversification

With methane, ethylene, acetylene and other gas detection capabilities (more gas detection solutions can be provided according to customer needs).
