Abstract

The invention relates to a compulsory mixed tail gas furnace. An igniter is communicated with a burner inner pipe; a composite air distribution blade is positioned at the other end of a burner, and is communicated with a combustor; a primary air inlet is arranged on a shell of the combustor; a vortex guide vane is positioned in an air chamber between the primary air inlet and the composite air distribution blade; the combustor is sequentially communicated with an air cavity and a tail gas cavity; a secondary air inlet is arranged out of the shell of the combustor at the air cavity, and the air cavity is communicated with the combustor; a vortex mixing blade is installed at the connecting end of the combustion chamber and the tail gas cavity; and an inner shunting and accelerating mixing blade and an outer shunting and accelerating mixing blade are installed at a tapered end of the combustion chamber, and are fixed at the inner surface of a fire-proof lining of the combustion chamber. The structure has the characteristics that the fuel gas and air are mixed fully, the combustion is complete, the heat energy utilization is full, and the like; and the hydrogen sulfide content in the tail gas is reduced obviously, which plays an active role in pushing the integral performance and environment protection of a tail gas burning device.

Description

technical field [0001] The invention relates to a horizontal forced mixed tail gas burning furnace for sulfur recovery and tail gas treatment. Background technique [0002] The tail gas incinerator is an important equipment in the sulfur recovery and tail gas treatment process. Its main function is to purify the H 2 The tail gas of S is incinerated and discharged into the atmosphere. Most of the differences among existing exhaust gas burners are in the structure of the burner and the way of air distribution. Traditional tail gas burners are roughly divided into two structural types: primary air intake and secondary air intake. Tail gas incinerators used in sulfur recovery and tail gas treatment processes mostly use high-efficiency swirl inlets, and use secondary air distribution to mix tail gas and high-temperature flue gas to achieve incineration effects. Restricted by technical conditions and structure, the exhaust gas burning furnace still has the following technical p...
