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.
