Leakage alarm linkage system and linkage alarm exhaust method

Abstract

The invention belongs to the technical field of laboratory gas bottle internal pressure monitoring, and particularly relates to a leakage alarm linkage system and a linkage alarm exhaust method. The leakage alarm linkage system mainly comprises a normally-open pneumatic valve, a normally-closed pneumatic valve, a leakage alarm probe, a leakage alarm host, a linkage anti-explosion exhaust device, alinkage closing device and a hazardous gas dilution device. The leakage alarm probe is installed near a hazardous gas bottle. When gas leakage is sensed, a signal is transmitted to the leakage alarmhost installed in a master control room or a manager office, the leakage alarm host gives out a sound-light alarm to inform a manager to carry out emergency treatment, meanwhile, the signal is transmitted to the linkage anti-explosion exhaust device and the linkage closing device, the linkage anti-explosion exhaust device is started, high-power exhaust is started, the linkage closing device is started, hazardous gas is prevented from being continuously output, the hazardous gas dilution device outputs inert gas to dilute the hazardous gas, the hazardous gas is exhausted outdoors through an exhaust pipeline, and therefore indoor safety is automatically guaranteed, and potential safety hazards are systematically eliminated.

Description

technical field [0001] The invention belongs to the technical field of pressure monitoring inside a laboratory gas cylinder, and in particular relates to a leakage alarm linkage system and a linkage alarm exhaust method. Background technique [0002] At present, with the development of science and technology and the increase of laboratory instruments, various gases need to be used, including flammable, explosive, toxic, corrosive and other gases. This kind of gas is stored indoors (instrument room) with greater safety. Hidden dangers, especially in the past two years, China University of Mining and Technology exploded with methane gas, causing one death and four injuries; Causing varying degrees of casualties, if there is a device that can quickly detect these leaked dangerous gases and give early warning in time, the potential safety hazard can be reduced to the lowest point.

Problems solved by technology

[0003] In the early gas detection and alarm devices, when the gas leaks, the alarm device reminds the management personnel to deal with it. If the management personnel is not present, the dangerous gas cannot be automatically discharged. The existing leakage alarm device has added an automatic exhaust device and an automatic shut-off device. When there is a gas leak, the alarm device will activate the exhaust device and the gas shut-off device at the same time as the alarm, cut off the output of the dangerous gas, and discharge the dangerous gas outside in time, but at this time there is still gas in the gas delivery pipeline, fundamentally The risk of hazardous gases has not been completely eliminated
