Therefore, the safe and stable operation of the emergency torch device is of vital importance to the safe production of enterprises. However, the existing technology usually has the risk of insufficient contact between the torch and the air, resulting in deflagration and incomplete combustion that damages the environment. Therefore, an emergency torch device with a simple structure, easy operation and high safety factor is needed. The existing technology focuses on sufficient combustion and heat utilization. For example, the CN211600734U ground torch, the cylinder is fixed by a bracket, leaving space for the cylinder to enter the air, and a fixing frame is also provided, etc., and its construction and material costs are high. Another example is the CN212108448U, a fully burned biogas torch, which uses a fan to suck hot air into the heating sleeve, heats the biogas inlet pipe, vaporizes the water in the biogas into water vapor, and then condenses it to eliminate part of the water contained in the biogas, so that the biogas burns more fully.
