Abstract

The invention discloses an anti-explosion torch. The anti-explosion torch comprises a connecting flange, a gas mixing pipeline and a torch head. A cooling gas channel is arranged in the middle of the torch head and is vertically through. An annular cavity is defined by a shell of the torch head and the cooling gas channel. The annular cavity, heat dissipation flow division pipes and the gas mixing pipeline are sequentially connected and communicate with one another. The heat dissipation flow division pipes are annularly distributed. The gas mixing pipeline is filled with a low-temperature flame-arresting net. The annular cavity is filled with a high-temperature flame-arresting net. The cooling gas channel and the heat dissipation flow division pipes play a role in cooling. The low-temperature flame-arresting net and the high-temperature flame-arresting net can prevent an explosion caused by pipeline backfire in the combustion process. Once the explosion happens, cooling gas enters the explosion region, the high temperature generated due to the explosion is lowered through cooling, high pressure generated due to the explosion is relieved through the low-temperature flame-arresting net and the high-temperature flame-arresting net, and the pressure and the temperature of the gas mixing pipeline are within the normal range, so that the anti-explosion effect is achieved. Air inlets around a rectifying air inflow pipe are formed between the gas mixing pipeline and the torch head and matched with the heat dissipation flow division pipes to play a role in airflow adjustment and sound attenuation.

Description

technical field [0001] The invention belongs to the technical fields of petroleum and oil shale exploitation and petrochemical industry, and in particular relates to an explosion-proof torch. Background technique [0002] Flare is a special combustion facility used to deal with combustible gas and combustible toxic gas that cannot be recovered and reprocessed from petrochemical plants, refineries, chemical plants and coke ovens. The hydrocarbon gas and acid gas are combusted and discharged in time. The torch system is an important facility to ensure the safe production of the factory and reduce environmental pollution. The stable operation of the flare system plays a vital role in safe production. With the enlargement of refining and chemical equipment and the increase of refining complexity, the amount of flare gas entering the flare system in emergency situations increases, and the operation risk of the flare system increases. The operation and management of the flare sy...
