Description

A New Type of Combustible Gas Alarm

technical field

The utility model relates to the technical field of combustible gas detection, in particular to a novel combustible gas alarm instrument.

Background technique

The combustible gas alarm is also called a gas leak detection alarm instrument. When the combustible gas leaks in the industrial environment and daily life environment (such as a kitchen using natural gas), the combustible gas alarm detects that the concentration of the combustible gas reaches the alarm value set by the alarm. The combustible gas alarm will emit sound and light alarm signals to remind people to take safety measures such as evacuation of personnel, forced exhaust air, and shutdown of equipment. In addition, the gas alarm can be linked to related linkage equipment. If there is leakage in the factory production, storage and transportation, it can drive the exhaust, cut off the power supply, spray and other systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. It is often used in chemical plants, oil, gas stations, steel plants and other places where flammable gases are used or generated. However, for some slight flammable gas leakage, especially the slight change of concentration caused by the leakage of flammable gas in non-closed space, the detection response of the flammable gas sensor probe based on catalytic combustion type is slow, and it is difficult to locate accurately.

CN208335435U discloses a combustible gas alarm device. The right side of the box body is provided with a combustible gas detector, and a wireless signal transmitter is installed on the right end wall of the box body. The alarm information can be transmitted to the control room through the wireless transmitter. The signal of the wireless signal transmitter cannot achieve the signal transmission effect because the signal is blocked by the building, and the positioning effect is relatively poor.
