Description
Technical Field
The invention relates to the technical field of flammable gas detection alarm, in particular to an automatic flammable gas detection alarm.
Background
The combustible gas detection alarm is a technical means for monitoring the concentration of the combustible gas in the environment in real time by using specific instruments and equipment and sending out an alarm when the concentration of the combustible gas reaches or exceeds a set safety threshold. Through combustible gas detection alarm, can reduce the economic loss such as equipment damage, production interruption that lead to because of combustible gas leaks, can also in time discover that combustible gas leaks simultaneously, avoid taking place dangerous such as explosion, conflagration, protect personnel's life. Accordingly, there are regulations in many industries that require the installation of flammable gas detection alarm devices to ensure safe production.
The combustible gas detection alarm is a device for detecting the concentration of combustible gas in the environment and giving an alarm when a dangerous threshold is reached, and generally consists of a sensor, a signal processing circuit, an alarm device and the like. The sensor can sense the existence of the combustible gas and convert the combustible gas into an electric signal, the signal processing circuit analyzes and processes the signal, and when the concentration of the combustible gas exceeds a set safety limit value, the alarm device can give out an audible and visual alarm to remind people to take corresponding safety measures so as to avoid dangerous accidents such as fire and explosion caused by the leakage of the combustible gas.
The existing automatic alarm for detecting the combustible gas needs to be installed in the area where the leakage possibility of the combustible gas exists, and the installation height of the alarm is related to the ratio of the detected gas to the air molecular weight. When the ratio of the measured medium to the molecular weight of the air is larger than 1.2, the gas which is heavier than the air is leaked and then downwards diffused and accumulated, and the installation height of the detector is 0.3-0.6 m higher than the ground in consideration of preventing damage to the alarm caused by dust, water stains and the like on the ground on site. In contrast, when a combustible gas such as hydrogen or acetylene lighter than air leaks, the gas rapidly diffuses and rises. In order to achieve the desired detection effect, the alarm needs to be installed within the range of 0.5-1.5 m above the release source. Because the automatic alarm for detecting the combustible gas can detect different types of combustible gas, and when detecting different combustible gas, the detection height of the alarm is different, but because the alarm is usually fixedly installed on the side wall of the detected area, when the detection height of the alarm needs to be changed, the alarm needs to be detached and reinstalled, and the height conversion when detecting different types of combustible gas in the area by the alarm is not facilitated, so that the alarm is very inconvenient to use.
