With the frequent occurrence of various types of gas explosion accidents, the installation of combustible gas detectors is now required in many places. Its gas detector is the 1 fixed gas detection alarm instrument, installed in the appropriate position and height can be long-term monitoring of nearby combustible gas concentration, and in the event of a leak timely alarm, to avoid casualties. Therefore, we in the combustible gas detector, for its installation position and height are required. Do you know the installation position and height requirements of combustible gas detector ? The following is a brief introduction by yi yun Tian:

Combustible gas detector installation position and height requirements:

1. combustible gas detector installation location

According to relevant regulations, the installation position of the detector is determined according to the density and wind direction of the detected gas, but the detector should be avoided in the place where the air flow is too large.

in general, the indoor space combustible gas detector is installed within 7.5m from the release source or within 15m from the horizontal distance between the two detectors; The toxic gas detection radius is 1m. For the indoor space with too large area or a large number of ventilated parts, the detector shall be arranged according to the outdoor situation. When the combustible gas detector is installed outdoors, it should be arranged on the windward side of the annual small frequency wind direction of the combustible gas release source, and the distance from the release source should not be greater than 15m; When the detector is arranged on the downwind side of the annual small frequency wind direction of the combustible gas release source, the distance from the release source should not be greater than 5m, and the toxic gas should be less than 2m.

2. combustible gas detector installation height

combustible gas detector installation height should be installed according to the proportion of combustible gas.When detecting combustible gas heavier than air, the installation height of the detector should be 0.3~0.6m from the ground; when detecting combustible gas lighter than air, the installation height of the detector should be 0.5~2m higher than the release source.

For gases such as hydrogen, it should be installed on the roof and other high places. Note: Gas density greater than 0.97kg/m3 (standard state) is considered heavier than air, gas density less than 0.97kg/m3 (standard state) is considered lighter than air.

To sum up, it is the installation position and height requirements of combustible gas detectors. In the process of installing the combustible gas detector, as long as we carefully follow the position and height requirements, we can more effectively ensure that the combustible gas detector can accurately and effectively detect the value of combustible gas, so as to better ensure our Personal safety.
