According to the "Shiyan release" official account of WeChat, the Shiyan City Public Security Bureau has taken criminal detention measures against 8 suspect, including Huang Dong, general manager of Shiyan Dongfeng Middle Gas City Gas Development Co., Ltd.

After the gas explosion accident in Yanhu community fair market in Zhangwan District, Shiyan City, Hubei Province, the Hubei provincial Party committee and government immediately set up an investigation team to investigate, and the public security organ of Shiyan City also filed an investigation at the same time. According to the preliminary findings, the Shiyan city public security organs have taken criminal detention measures against 8 suspect, including Huang, a general manager of Shiyan Dongfeng gas burning city gas development Co., Ltd.

After the gas explosion accident in Yanhu community fair market in Zhangwan District, Shiyan City, Hubei Province, the Hubei provincial Party committee and government immediately set up an investigation team to investigate, and the public security organ of Shiyan City also filed an investigation at the same time. According to the preliminary findings, the Shiyan city public security organs have taken criminal detention measures against 8 suspect, including Huang, a general manager of Shiyan Dongfeng gas burning city gas development Co., Ltd.

According to the preliminary investigation, the natural gas pipeline in which the accident occurred was owned by Shiyan Dongfeng zhongran City Gas Development Co., Ltd. the company's safety management system was not perfect, the responsibility was not implemented, the gas pipeline patrol inspection system was not strictly implemented, and there were serious defects in the operation of relevant equipment.

At present, the accident investigation is being carried out in depth. After the investigation is completed, the relevant units and individuals will be held accountable according to law and discipline.

Accurate and rapid warning of gas safety is the top priority of the safety operation of cities and enterprises.

Hanhai optoelectronic's laser spectrum absorption technology can actively monitor the risk nodes of gas leakage, instead of waiting for the gas to diffuse to the equipment. High sensitivity, can detect early micro leakage, in the early stage of the hidden danger can prompt, will alarm into early warning. It can run stably for a long time without regular adjustment, which can reduce staff and increase efficiency for the enterprise. Fingerprint detection, not affected by environmental conditions, provide reliable and accurate monitoring data, 0 false alarm. Millisecond level detection speed, as long as there is leakage gas can be found immediately, 0 missing report.

Portable remote sensing laser methane detector

The portable remote sensing laser methane detector can realize the remote sensing of methane gas, realize the remote and rapid detection of the area that is not easy for personnel to reach, and avoid the detection personnel from being injured when entering the gas leakage area.

Fixed scanning laser gas telemeter

The fixed scanning laser gas telemeter can monitor methane gas concentration by radar 360 degree rotary scanning within 300 meters radius. It can monitor the gas concentration in real time and high-definition video, and can monitor the leakage position.

Fixed reflection laser gas telemeter

The fixed reflection laser gas telemetry instrument consists of the transmitter and the reflecting end, and the monitoring distance can reach 1km. The remote on-line leakage monitoring of micro gas can be realized in real time, fast, continuous and reliable on a wide range and ultra long-distance open path. Multi equipment networking can realize real-time online monitoring of gas distribution area, distribution concentration, mobile speed and moving direction.

Laser gas leakage monitor for Internet of things

The laser gas leakage monitor of Internet of things includes fixed-point laser methane leakage monitoring sensor and management platform software installed on site. The detector adopts highly integrated design, which integrates laser emission and control, spectral analysis into the module to realize the complete methane detection function of laser absorption spectrum. The unique modular design can be used as an independent fixed-point laser methane leakage monitoring sensor, and can directly replace the detection part of the traditional methane detector to achieve productupgrading.

Vehicle mounted laser inspection system

The vehicle mounted inspection system loads the front mounted and top mounted laser detection equipment and Beidou / GPS positioning device on the inspection vehicle. The inspection vehicle can quickly obtain the inspection track and inspection data (whether there is leakage, leakage concentration, leakage location) and accurately locate the inspection data along the natural gas pipeline road at a speed of 50 km / h, and transmit the 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 inspection vehicle, which is used to detect the micro leakage of the underground pipeline within 5 meters from the 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 road of the inspection vehicle.

Electric vehicle laser inspection system

The inspection electric vehicle is equipped with laser detection equipment and digital display. The electric vehicle inspects along the natural gas pipeline road at a speed of 20 km / h. the display can display the real-time gas concentration value and has sound and light alarm function.

UAV laser inspection system

The inspection UAV is equipped with laser inspection equipment and Beidou / GPS positioning device to realize rapid inspection of ground facilities or high-altitude facilities from the air.
