Comprehensive solution for gas safety in “three-in-one” places

In every corner of the city, “three-in-one” places are widely distributed. While they bring convenience to people’s lives, they also hide huge safety hazards. Due to the complex functions, dense personnel, and imperfect fire-fighting facilities of such places, once a gas safety accident occurs, it often causes serious casualties and property losses. Therefore, it is urgent to build a scientific and effective comprehensive solution for gas safety in “three-in-one” places.

Analysis of gas safety hazards in “three-in-one” places

1. High risk of gas leakage: In “three-in-one” places, various flammable gases, such as natural gas and liquefied gas, may be used in production and business activities. Due to aging equipment, improper operation, pipeline damage and other reasons, the probability of gas leakage is relatively high. Moreover, many places lack regular equipment maintenance and inspection mechanisms, and cannot detect and deal with potential leakage problems in time.

2. Poor ventilation conditions: Such places usually have relatively closed spaces, insufficient ventilation facilities or poor operation. Once a gas leak occurs, it is difficult for the leaked gas to be quickly discharged outdoors, increasing the risk of explosion and fire.

3. Electrical equipment triggers sparks: If the electrical equipment in the venue does not have explosion-proof functions, or generates electric sparks and arcs during use, it is easy to ignite leaked flammable gases and cause serious safety accidents. In addition, illegal behaviors such as private wiring and overloading electricity are also common, which further aggravates the hidden dangers of electrical fires.

4. Weak safety awareness of personnel: Some employees and residents of “three-in-one” venues have little knowledge of gas safety and lack basic safety awareness and emergency response capabilities. In the event of emergencies such as gas leaks, correct response measures may not be taken, resulting in the expansion of the consequences of the accident.

1. Intelligent monitoring system construction

Deployment of combustible gas detectors: According to the area, layout and gas usage of the venue, combustible gas detectors should be reasonably installed. For gases lighter than air, such as natural gas, the detector should be installed 0.3-0.6 meters from the ceiling; for gases heavier than air, such as liquefied gas, the detector should be installed 0.3-0.6 meters from the floor, and the probe should always face downward. The detector uses a high-precision sensor that can quickly and accurately detect gas leaks. It also has explosion-proof and waterproof (IP66) functions and can adapt to complex environments.

2. Efficient alarm

When the combustible gas detector detects that the gas concentration exceeds the alarm value, it immediately triggers a local sound and light alarm to remind people in the venue to pay attention to safety. At the same time, the alarm information is pushed through the APP so that the owner can understand the situation at the first time. At the same time, the solenoid valve will automatically cut off the gas source to prevent further gas leakage, and start the exhaust equipment to accelerate indoor air circulation and reduce gas concentration.

3. Closed-loop management and intelligent operation and maintenance

Establishment of digital ledger: Use the cloud big data platform to establish a “three-in-one” digital ledger of gas safety in the venue. The ledger records information such as equipment status, inspection records, and historical data of gas concentration to achieve visual management of data. Managers can view the ledger at any time through computers or mobile phones to understand the safety dynamics of the venue, discover potential problems in time and take measures.

Intelligent operation and maintenance and fault diagnosis: The system has intelligent operation and maintenance functions, and the equipment can perform fault self-detection. Once a device failure is detected, a notification is immediately sent to the operation and maintenance personnel to inform them of the type and location of the failure. At the same time, the system can regularly perform remote calibration of the equipment to ensure the accuracy and reliability of the equipment. Through intelligent operation and maintenance, the workload of manual inspections can be greatly reduced, the efficiency of equipment maintenance can be improved, and the equipment failure rate can be reduced.
