Safe transportation device for high-pressure combustible experimental gas and gas supply method thereof

Abstract

The invention discloses a safe transportation device for high-pressure combustible experimental gas and a gas supply method thereof. The device comprises a combustible experimental gas cylinder, an inert gas cylinder, a filter, a pipeline pressure reducing valve, a manual stop valve, a pneumatic stop valve, a pressure transmitter, a vacuum pump, a pressure gauge, a vacuum gauge, an electromagneticvalve, a combustible gas detector, a combustible gas alarm controller, a metal pipeline and the like. The device can be used for: 1) transporting the combustible gas to experimental equipment safely;2) adjusting the gas pressure in full range during the using process; 3) supplying gas continuously or intermittently for laboratory equipment; 4) conduting air tightness inspection to the equipmentbefore the experiment and supplying gas for cleaning tail gas after the experiment; 5) replacing the high-pressure gas cylinder safely and conveniently; 6) detecting combustible gas concentration in real time to maintain laboratory safety. With good air tightness, high cleanliness, high durability and safety reliability, the transportation device and method provided by the invention can meet the requirements of continuous gas supply and intermittent gas supply for the laboratory equipment.

Description

technical field [0001] The invention relates to a transport system for flammable test gas, in particular to a safe transport device for high-pressure flammable test gas and a gas supply method thereof. Background technique [0002] Flammable experimental gases include hydrogen, acetylene, methane, etc., which are often delivered to experimental devices and instruments by gas cylinders through pipelines. However, improper gas transportation and use may cause flammable gas leakage. Once it encounters an ignition source, it is very easy to cause a fire and explosion accident, resulting in casualties and property losses. For example, an explosion occurred in a university laboratory in 2015, resulting in the death of one person. It was initially confirmed that the gas explosion was caused by improper use of hydrogen. How to ensure the safe transportation and operation of laboratory flammable gases, especially high-pressure gases, is a problem that needs to be paid attention to i...

Problems solved by technology

Decentralized gas supply is easy to operate and saves gas, but poor safety; centralized gas supply has high reliability and strong functionality, but the gas supply pipeline is long and wastes gas. It is inconvenient to use the gas cylinder to turn on or off the gas source
