At about 23:00 on the 22nd, an explosion occurred in a chemical plant in the Alxa League high tech Industrial Development Zone. At present, four people have been killed and three injured.

    It is reported that at about 23:00 on the 22nd, a flash explosion occurred in the oxidation workshop of Inner Mongolia Zhonggao Chemical Co., Ltd. in Bayin OBO Industrial Park, resulting in four deaths, one serious injury and two minor injuries. The open fire on the site was extinguished at 0:50 on the 23rd. At present, the legal representative of the enterprise has been controlled by the public security organ, all on-site operators have been evacuated, and the enterprise is gradually stopping production.

    After the accident, Alxa League public security, emergency, fire and other departments rushed to the scene to carry out rescue and disposal work. The emergency management department of Inner Mongolia Autonomous Region timely dispatched the accident rescue and disposal, and sent a working group to the scene overnight to guide the accident rescue and disposal.

    It is reported that the people's Government of Inner Mongolia Autonomous Region has set up an accident investigation team to raise the level to investigate and deal with the accident. The cause of the accident is under further investigation.

  The newly revised production safety law of the people's Republic of China came into force on September 1 this year, which revised the responsible person. Article 5 of the new work safety law clearly stipulates that the main person in charge of the production and business operation unit is the first person responsible for the work safety of the unit and is fully responsible for the work safety of the unit. Other responsible persons shall be responsible for the work safety within their scope of responsibility.

Sharp、Accuracy、reliability

The recent explosion accident due to gas leakage is still vivid, which reminds us that the intelligent control of gas leakage detection is so important.

Article 5.2.3-6 of GB / T 50493-2019 design standard for detection and alarm of combustible and toxic gases in petrochemical industry points out that linear combustible and toxic gas detectors should be selected in open areas with special climatic environment or production environment.

The application products of Hanhai photoelectric's laser spectral absorption technology can actively monitor the risk nodes of gas leakage without waiting for the gas to diffuse to the equipment and change from passive to active.

01 high sensitivity

Trace gas leakage can be accurately detected and the reaction speed can be less than 0.1 second. It can prompt at the early stage of hidden danger and change the alarm into early warning

02 high monitoring accuracy

It can achieve "fingerprint" detection, provide reliable and accurate monitoring data, 0 false positives and completely eliminate false positives

03 strong anti-interference ability

It will not be disturbed by humidity, dust, temperature and other gases, and can work in high humidity environment for a long time

04 stable

Long term stable operation, safer and more reliable.

According to article 5.2.3-9 of GB / T 50493-2019 design standard for combustible gas and toxic gas detection and alarm in petrochemical industry, mobile gas detection and alarm device shall be equipped for inspection (maintenance) operation, confined space operation, hot work and other places requiring temporary detection of "combustible gas and toxic gas".

Portable telemetry laser methane detector

The portable telemetry laser methane detector can realize the remote telemetry of methane gas, realize the remote and rapid detection of areas that are not easy for personnel to reach, and avoid the detection personnel from entering the gas leakage area to be injured.

At the same time, according to the needs of the required detection area, the chemical park can also meet the daily inspection work by configuring fixed scanning laser gas telemeter, fixed reflection laser gas telemeter, vehicle mounted laser inspection system, electric vehicle mounted laser inspection system or dangerous gas detection robot.

Fixed scanning laser gas telemeter

The fixed scanning laser gas telemeter can conduct radar 360 degree rotation scanning within a radius of 300m to monitor the methane gas concentration, conduct remote online visual intelligent monitoring by means of real-time monitoring gas concentration data combined with high-definition video, and locate the leakage direction.

Fixed reflection laser gas telemeter

The fixed reflection laser gas telemetry instrument is composed of transmitting end and reflecting end, and the monitoring distance can reach 1km, so as to realize real-time, fast, continuous and reliable remote online leakage monitoring of trace gas on a large-scale and ultra long-distance open path. Multi equipment networking can realize real-time online monitoring of gas distribution area, distribution concentration, moving speed and moving direction.

Vehicle mounted laser inspection system

The vehicle mounted inspection system loads the front mounted and overhead laser detection equipment and Beidou / GPS positioning device on the inspection vehicle. The patrol inspection vehicle carries out patrol inspection along the natural gas pipeline road at 50km / h, which can quickly obtain the patrol inspection track and patrol inspection data (whether there is leakage, leakage concentration and leakage location) and accurately locate, and transmit the patrol inspection data to the monitoring center or on-board tablet computer in real time or regularly.

Vehicle mounted front laser detector

The subsystem is installed in the front of the patrol inspection vehicle to detect micro leakage of underground pipelines within 5m from the patrol inspection vehicle.

Vehicle mounted overhead laser detector

It is installed on the top of the vehicle to detect the leakage of underground pipelines buried under the green belt and sidewalk, which are far away from the driving road of the inspection vehicle.

Electric vehicle mounted laser inspection system

The patrol electric vehicle is equipped with laser detection equipment and digital display. The electric vehicle carries out patrol inspection along the natural gas pipeline road at 20 km / h. the display can display the real-time gas concentration value and has the function of audible and visual alarm.

Dangerous gas detection robot

Dangerous gas detection robot is the only multi gas detection robot in China. It has highly intelligent technologies such as robot positioning, environment modeling, navigation technology and image recognition, with slope climbing performance of 10% and maximum driving speed of 15km / h. It has wide-angle camera, searchlight and audible and visual alarm equipment, which can realize walking, steering and braking through remote control. Methane, hydrogen sulfide, carbon monoxide, carbon dioxide, oxygen, sulfur dioxide and nitrogen dioxide can be detected at the same time, and the collected data can be uploaded in real time. Remote wireless communication at a distance of 500 meters is realized through radio ad hoc network. It can support no more than 2 channels of HD video transmission at the same time.

Hanhai photoelectric laser absorption spectrum gas monitoring products truly achieve the sensitivity, accuracy and reliability of gas detection! Escort the safety of people's lives.
