Description

A alarm device for methane gas detects

Technical Field

The utility model relates to the technical field of methane detection equipment, in particular to an alarm device for methane gas detection.

Background

The specific gravity of methane to air is 0.54, the methane is lighter than air and is gathered above a coal mine tunnel, and the methane gas is colorless, tasteless, flammable and slightly toxic. When the methane gas in the air reaches 5-15% (volume fraction), the ignition will explode, and the methane accounts for more than 9.5% of the air in volume fraction, and the explosion is most intense. Methane, although slightly toxic, reduces the atmospheric oxygen partial pressure at high concentrations, resulting in insufficient oxygen supply, resulting in anoxic asphyxiation, which immediately kills people when it is present in excess of 40% in the air. In the methane monitoring and monitoring link, the reliability and the sensitivity of the methane sensor are directly related to the reliability and the sensitivity of a coal mine safety monitoring system, are eyes of the coal mine safety monitoring system, are key technical equipment for predicting and early warning of mine gas disasters,

at present, methane testing arrangement is when testing methane, and inconvenient staff carries testing arrangement, and the alarm mode is too single, can't arouse the staff fast and notice, can not be fine satisfies people's work demand.
