The cylinder is designed in an annular shape and is adaptive to circulating airflow, the upper part of the cylinder is provided with incremental perforations which are increased progressively according to the size of the cylinder of the acid gas torch, the caliber of the acid gas torch is 1 set of an igniter and 1 set of Changming lamp below DN200, the calibers of the acid gas torch are 2-3 sets of the igniter and the Changming lamp respectively from DN200-DN400, and the calibers of the acid gas torch are 3-4 sets of the igniter and the Changming lamp respectively from DN 400-700.

The flame spraying head is annularly cylindrical, and the streamline design, its flame spraying head top are provided with the flame spraying hole, and the overhead top of flame spraying is according to certain angle, and the flame spraying head cylinder central line becomes 60 ℃ promptly, and the hole is to up, and outer big-end-up opens the flame spraying hole to one side, and flame spraying hole blowout flame leads to next flame spraying head, and the class is igniteed, forms annular combustion zone, realizes the steady combustion.

The flame spraying holes are conical and are arranged at a certain angle, namely the central line of a flame spraying head cylinder is 60 ℃, the holes face upwards, the outer part is large, the inner part is small, and the flame spraying hole is upward, so that airflow can be conveniently injected; an annular flame is formed at the flare opening to cover the whole flare opening, so that the diffusion of sulfur-containing gas caused by different wind directions can be prevented. When the flame is sprayed from the nozzle, the flame is inclined upwards at a certain angle to drive the sulfur-containing gas to rotate and burn, so that the stirring effect is achieved, the wind resistance is improved, and the complete combustion degree is increased.

The utility model discloses an application method is, the utility model discloses a design is that wholly adopt the loop configuration barrel, and the barrel top increases progressively and sets up the gas pocket, and the gas pocket top sets up a plurality of flame spraying head, reachs best air inlet position through reasonable calculation, when the special combustor of acid torch burns, the combustible gas that introduces the loop configuration barrel by fuel gas pipe forms cyclic annular air current, and flame spraying hole blowout flame leads to next flame spraying head, and the class is igniteed, forms the annular combustion zone, realizes the multiple spot at last and discharges the burning, reaches the purpose of stable combustion.

The utility model has the significance that the traditional single-point emission combustion is changed into the multi-point emission combustion by the device, so that the defect of fire shedding in the combustion is overcome, the reliability of normal emission combustion is greatly improved, and the device is particularly suitable for an acid torch.
