In particular to a gas combustion device suitable for steel (iron) ladles, tundishes, iron mixing furnaces, steel rolling heating furnaces and heat treatment furnaces of iron and steel enterprises, combustion devices for heating or heat preservation of natural gas of copper clad, aluminum ladles, heat preservation furnaces (or smelting furnaces) and the like of nonferrous metal enterprises, matching devices of safety control interlocking systems of various production devices and conveying pipelines, and the like.
Background
At present, the known various combustion devices, production devices and equipment pipelines of iron and steel and non-ferrous metal (and chemical industry) enterprises are mostly only provided with nitrogen (or steam) purging pipe heads manually connected, and the automatic interlocking function cannot be realized. And some enterprises adopt the electromagnetic valve as a blowing facility, although automatic interlocking can be realized, the requirements of the relevant clause standards of GB6222 coal gas safety regulations of industrial enterprises are seriously violated. In addition, the pipelines (the diameter is larger than 159 mm) of the combustion devices of most enterprises are only provided with the quick cut-off valves of the pressure-free interlocking devices, and the requirements of the standards of the relevant provisions of GB6222 'gas safety regulations of industrial enterprises' are violated.
Taking steel enterprises as examples: when various combustion devices are extinguished before or after ignition, explosive gas exists in a pipeline behind a valve or the combustion device due to internal leakage defects of gas valves and the presence of unprecedented gas. In the state where no automatic device handles explosive gases, there is inevitably an explosion risk when re-ignition is performed. The same various combustion devices do not have the quick cutting function of the pressure maintaining interlocking device on the pipeline with the diameter larger than 100mm, and the risk of backfire explosion exists. And after the nitrogen purging is finished, only the electromagnetic valve is used for closing without reliable partition measures, and the risk of accidents is caused because the leakage of the nitrogen can cause mutual channeling.
