January 15, Liaoning Panjin Panshan County, a chemical plant fire explosion. That afternoon, Panshan County issued a notice saying that the Panshan County Hao ye chemical company alkylation plant in the maintenance of an explosion caused a fire.

On the afternoon of January 15, the propaganda department of the Mount Pan County Party Committee announced through the website of the Panshan County Financial Media Center that at 13:252023 on January 15, the alkylation unit of the Panshan County Hao ye chemical company, in the course of maintenance, an explosion caused a fire. After the accident, the city and county level quickly launched emergency plans, emergency on-site disposal and rescue work. At present, the cause of the accident investigation and personnel treatment is under way.

According to reports, Panjin explosion chemical plant safety responsible for voice, the explosion was due to alkylation device pipeline leak, the incident before workers were repairing the leaking pipeline.

In recent years, refining and chemical accidents continue, especially near the end of the year, the enterprises increased production safety risks, which need to be more vigilant. In its report to the 20th National Congress of the Communist Party of China (CPC) , the party called for Putting Safety First and putting prevention first, establishing a framework for major safety and emergency response, improving the public safety system, and promoting the transformation of the public safety governance model into an ex ante prevention model.

According to the cause of explosion and the characteristics of accident in chemical industry, it is more effective to use the gas leakage monitoring equipment which can actively monitor and have no false alarm.

Fixed reflection laser gas telemeter

The equipment is mainly used for the overall monitoring of large-scale space. It consists of two parts, one is a transmitter-receiver for laser control and spectral signal analysis, and the other is a pure optical reflector without power supply. The transmitting and receiving device is arranged at one end of the monitored area. The detection laser is transmitted from the transmitting and receiving device to the reflecting device and receives the returned spectral signal. The concentration monitoring results are obtained through analysis. The area between the transmitting and receiving device and the reflecting device is the monitored area, the monitoring range is up to 1 km. It can monitor methane, hydrogen sulfide, ethylene, acetylene, carbon monoxide, ammonia, hydrogen fluoride, hydrogen chloride and other gases on-line. In line with the national GB/T 50493-2019 standard.

In line with the national GB/T 50493-2019 standard

It conforms to GB/T 50493-2019 standard for detection and alarm design of combustible and toxic gases in petrochemical industry.

The detection area is wide

The fixed reflection laser gas telemeter can be detected for a distance of up to 1 km.

Preventive monitoring

Different from the traditional passive waiting mode, the active detection of leakage risk points. Response time is only 1 second, can accurately detect ppm micro-leakage. To realize the preventive monitoring of gas leakage.

Flexible and precise positioning

The laser emitting end and the receiving end are integrated at one end, and the other end is only provided with a reflecting device, so that the installation is convenient. By moving the positioning device, the leak source can be found quickly.

Strong anti-interference

Compared with the traditional detector, it is easy to be interfered by environment and cross gas. Fingerprint detection, truly achieve zero false positives.

Accurate measurement

The leakage gas concentration can be obtained quickly by the spectral inversion algorithm, and the sensitivity is up to 1 ppm. M, completely eliminate the phenomenon of false alarm and missing report.

“0” maintenance

The product need not adjust, but can save the operation cost in the whole life cycle.

Long Life

The service life of the product is up to 10 years.

Detect gas diversity

Can be methane, hydrogen sulfide, ethylene, acetylene, carbon monoxide, ammonia, hydrogen fluoride, hydrogen chloride and other gases on-line real-time detection (according to customer demand to provide more gas detection program) .
