[0001] This utility model relates to the field of industrial gas treatment technology, and in particular to a device for harmless combustion and replacement of combustible gases in gas cylinders. Background Technology

[0002] Industrial gas cylinders (such as natural gas cylinders and solvent cylinders) often leave behind flammable and harmful gases after use. Traditional disposal methods often involve direct discharge or open-air burning, which poses risks of explosion and environmental pollution. Utility Model Content

[0003] To address the problem of direct emission of flammable and harmful gases from industrial gas cylinders, which pollutes the environment and poses an explosion risk, this application provides a device for the harmless combustion and replacement of flammable gases in gas cylinders.

[0004] The technical solution of the device for harmless combustion and replacement of combustible gas in a gas cylinder provided in this application is as follows: A device for harmless combustion and replacement of combustible gas in a gas cylinder, installed on a wall, includes a main pipe for connecting the gas cylinder and conveying combustible gas, a secondary pipe connected to the main pipe, a first manual valve, a second manual valve, a protective frame, an ignition device, and a pressure gauge. Both the main pipe and the secondary pipe are installed on the wall. The main pipe is vertically oriented. The first and second manual valves are respectively installed on the main pipe and the secondary pipe. A quick-connect fitting for connecting to the gas cylinder is connected to the bottom end of the main pipe. The pressure gauge is installed on the secondary pipe. The protective frame is installed on the wall, with the top of the main pipe located within the protective frame. The ignition device is installed within the protective frame, with its ignition head close to the top of the main pipe.

[0005] Preferably, a first fixing plate and a second fixing plate are connected to the wall surface, the first fixing plate being used to connect the main pipe and the second fixing plate being used to connect the secondary pipe.

[0006] In summary, this application includes the following beneficial technical effects: This utility model provides a device for the harmless combustion and replacement of combustible gases in gas cylinders. By setting up a main pipe, a secondary pipe, a first manual valve, a second manual valve, a protective frame, an ignition device, and a pressure gauge, the dual-pipeline design (main pipe and secondary pipe) combined with independent valves (first manual valve and second manual valve) physically isolates the combustion and replacement processes, avoiding the risk of gas mixing. The protective frame isolates the combustion process and prevents flame overflow, thereby achieving the effect of improving the problem of direct emission of combustible and harmful gases from industrial gas cylinders, which pollutes the environment and poses an explosion risk.
