Novel fuel oil purging device

The utility model discloses a novel fuel oil purge, which comprises a gas transmission assembly, a heating assembly and a purge assembly, an operator can insert a purge pipe into a fuel oil pipeline in advance, at the moment, a suction pump is started to enable a gas inlet pipe to pump gas into a gas transmission pipe, and at the moment, a first valve can be opened to enable the gas to enter the inner side of a gas storage cylinder through the gas transmission pipe; then, an air compressor can be started to extract gas on the inner side of the gas storage cylinder, when the gas is on the inner side of the gas storage cylinder, a heating pipe can heat the gas, the temperature of the gas during flowing is increased, the gas can be better purged and support combustion, and at the moment, the heated gas is extracted and compressed by the air compressor to enter the inner side of a gas guide pipe; and an operator can open the second valve to enable the compressed high-temperature gas to be sprayed outwards through
