The revised national standard safety code for special operations in hazardous chemical enterprises (GB 30871-2022) organized by the emergency management department has been officially released and will be implemented on October 1, 2022. In the revised new standard, it is mentioned for many times that enterprises that produce, operate (store) hazardous chemicals and chemical and pharmaceutical enterprises need to be equipped with mobile gas detection and alarm devices to monitor the concentration of combustible gas, toxic gas and oxygen during operation.

For dangerous chemical enterprises, the risk of safety production and the importance of safety work are self-evident. It also has the challenge of detecting various gases and complex environment. So how can we accurately and quickly identify hidden dangers of gas leakage?

The traditional gas detectors are unstable, easy to be disturbed, and have high false alarm rate. In this regard, Hanhai technology group, in cooperation with the Chinese Academy of Sciences, undertook the industrialization of laser absorption spectrum gas detection technology, a major national scientific research achievement. The equipment can realize on-line, high accuracy, calibration free, highly sensitive and reliable detection under the environment of strong acid, strong alkali and various gas interference.

Fixed reflection laser gas telemeter

Hanhai photoelectric fixed reflection laser gas telemetry instrument is composed of laser control unit, spectral analysis unit and optical reflection unit. It adopts laser absorption spectral gas detection technology (TDLAS) to conduct long-distance all-weather online monitoring of gas concentration between laser transceiver and reflection device. Through the networking of multiple devices, the real-time monitoring of the distribution concentration, moving speed and moving direction of different component gases can be realized. It is an ideal choice for monitoring gas leakage in a large open area. It is very suitable for the scenario application of hazardous chemical production enterprises, hazardous chemical storage enterprises and chemical industry parks.

01. Wide detection area

The fixed reflection laser gas telemeter can detect methane at a distance of 1km, and can detect ethylene, acetylene, hydrogen sulfide and other gases at a distance of 200m.

02. Preventive monitoring

Different from the passive waiting of traditional detection mode, it actively monitors the leakage risk points. The response time is only 1 second, which can accurately detect ppm level micro leakage. Truly realize the preventive monitoring of gas leakage.

03. Convenient installation

The laser transmitting end and receiving end are integrated at one end, and the other end is only equipped with a reflecting device, which is convenient to install.

04. Strong anti-interference ability

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 alarm.

05. Accurate measurement

The leakage gas concentration is quickly obtained by spectral inversion algorithm, and the sensitivity is up to 1ppm m. Completely eliminate the phenomenon of false positive and false negative.

06. "0" maintenance

The product does not need to be adjusted, which can save operation in the whole life cyclcost.

07. Long service life

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

08. Detection of gas diversification

Gas detection type: methane, carbon monoxide, hydrogen sulfide, and ethylene Alkene, acetylene and ammonia (more gas detection schemes can be provided according to customer needs)

For the mobile gas detector required in the new standard, it can also intelligently detect the chemical industry park through the inspection robot.

Safety protection intelligent robot

The safety protection intelligent robot is applicable to combustible gas detection, routine work inspection and other scenes in the chemical industry park. With 1000m long-distance wireless communication capability, Q235 metal skeleton crawler structure.

It can monitor methane, carbon monoxide, carbon dioxide, oxygen, nitrogen dioxide, hydrogen sulfide, sulfur dioxide, dust and noise in real time.

01. Firmer body

Adopt Q235 all metal framework crawler structure, and have effective shock absorption and anti-corrosion treatment.

02. Faster

The walking speed is more than 1.5 meters per second, and the speed can be adjusted according to the needs of the scene.

03. Smoother travel

It has the function of autonomous obstacle avoidance. With 200mm obstacle clearance height and 35 ° climbing performance, it can easily climb over various steep and potholes on the site. The 37 ° roll makes the vehicle more stable.

04. Strong endurance

Powered by lithium battery, it can work continuously for 12 hours.

05. Strong anti-interference ability

It will not be interfered by humidity, dust, temperature and other gases, and can work in a high humidity environment for a long time to adapt to the changes of temperature environment at the tunnel site.

06. Multi gas monitoring

Real time detection of methane, carbon monoxide, carbon dioxide, oxygen, nitrogen dioxide, hydrogen sulfide and sulfur dioxide.

07. Safety construction process control

Add dust, noise and other numerical monitoring. Meet the occupational health and safety standard requirements of code for design of railway tunnels tb10003-201 on tunnel construction environment.

08. Longer telemetry distance

It supports WiFi, 4G and 5g wireless communication, and the remote control distance can reach 1000m.
