specific Embodiment 1

[0047] Such as Figure 2 to Figure 4 As shown, the sulfur recovery burner includes a primary unit, a secondary unit and a tertiary unit connected in series, and each unit is connected coaxially. During use, according to the load of the sulfur recovery burner, the units of each level are turned on in sequence. In this embodiment, for the convenience of description, it is defined that the primary unit, the secondary unit and the tertiary unit are arranged sequentially from front to rear, and gas and flame are also sprayed from front to rear.

[0048] Such as figure 2 As shown, the first-stage unit includes a first-stage combustion chamber 201 , a first-stage nozzle 202 is installed on the front side of the first-stage combustion chamber 201 , and the first-stage nozzle 202 is arranged coaxially with the first-stage combustion chamber 201 . A first-stage fuel passage is provided in the first-stage nozzle 202, and acid gas and air are supplied to the first-stage combustion chamb...

Embodiment 1

[0063] In Embodiment 1, the secondary combustion chamber has two stages. In this embodiment, the number of secondary combustion chambers can be changed according to the actual situation. For example, it can be three or more stages. The number of stages increases, and the number of nozzles in any two adjacent combustion chambers is the same, and they are evenly distributed along the circumferential direction.

specific Embodiment 3

[0065] In Embodiment 1, the secondary combustion chamber has two stages. In other embodiments, there may be only one secondary combustion chamber.

Abstract

The invention relates to the field of combustion technology and material recovery, in particular to a sulfur recovery combustor which comprises at least two stages of combustion chambers, the combustion chambers are sequentially communicated from front to back, the foremost combustion chamber is defined as a first-stage combustion chamber, and the combustion chamber behind the first-stage combustion chamber is defined as a second-stage combustion chamber; a first-stage nozzle is formed in the front end of the first-stage combustion chamber, a first-stage fuel channel is formed in the first-stage nozzle, and air and acid gas are introduced into the first-stage fuel channel and sprayed backwards; the first-stage nozzle is further provided with an ignition gun channel for an ignition gun to extend into for ignition, or the first-stage fuel channel can be used for the ignition gun to extend into. A secondary fuel inlet communicated with the corresponding secondary combustion chamber is formed in the side wall of the secondary combustion chamber, and fuel gas is sprayed into the secondary fuel inlet and ignited by flames in the secondary fuel chamber.

Description

technical field [0001] The invention relates to the fields of combustion technology and material recovery, in particular to a sulfur recovery burner. Background technique [0002] The gas produced from high-sulfur gas fields is rich in hydrogen sulfide, which is a highly toxic gas, and must be converted into elemental sulfur by a sulfur recovery device for recycling. The core equipment of the sulfur recovery unit is the sulfur recovery burner. The sulfur recovery burner burns the acid gas rich in hydrogen sulfide to cause a chemical reaction at high temperature, and part of the hydrogen sulfide is oxidized to sulfur dioxide, and then the sulfur dioxide is combined with the remaining unreacted Hydrogen sulfide reacts under the action of catalyst to produce sulfur. Its main reaction formula is: H 2 S+3 / 2O 2 = SO 2 +H 2 O; 2H 2 S+SO 2 =3S+2H 2 O. [0003] During the sulfur recovery process, the performance of the burner directly affects the processing capacity and conv...
