Abstract
The utility model relates to an annular space type combustor for a sulfur recovery device. The annular space type combustor comprises an air chamber, an acid gas chamber, a cooling chamber and a fuel gas chamber which are nested successively from the outside to the inside. A fuel gas mixer and a combustion chamber are arranged in the fuel gas chamber, space is formed between the inner wall of the cooling chamber and the outer wall of the fuel gas chamber, an acid gas director extending axially is arranged on the whole circumference of the inner wall of the acid gas chamber, and an air director extending axially is arranged on the whole circumference of the inner wall of the air chamber. According to the annular space type combustor, the requirement for small Claus technological combustion space of acid gases rich in impurities is met by controlling the flame shape. By means of an annular space type non-nozzle structure, risks of blockage of the combustor by tar drops in the acid gases are removed. Reaction time of impurities in the acid gases is increased, the impurities are fully heated and pyrolyzed, initial conditions are provided for the reaction of the impurities at a catalysis stage, and the characteristic is valuable and necessary for the narrow combustion stage of a sulfur production furnace.
Description
Technical field
The utility model relates to a kind of sulfur recovery facility with annular space formula burner, particularly relates to a kind of sulfur recovery facility that is rich in impurity acid gas annular space formula burner that is applicable to.
Background technology
Be rich in the impurity acid gas because containing a large amount of NH3, HCN, arene and sweep along a large amount of tar liquids to adopt WSA technology to reclaim element sulphur in the acid gas, as adopt traditional claus process will carry out preliminary treatment to acid gas.Must cause system more complicated thus, cost also can correspondingly improve.
Since claus process was come out, the sulfur recovery facility burner is constantly perfect, and was full-fledged so far.Be representative with the Du Ke burner, its basic principle is: H2S and combustion air O2 are by strong swirl-flow premixed realization burning, by shunting, oxygen-enriched air, pure oxygen is combustion-supporting or means such as local introducing pure oxygen improve furnace temperature and decompose hydrocarbon, Ammonia impurity in the acid gas.Yet after impurity content surpassed certain upper limit, the efficient of acid gas burning obviously descended, and handles the limited in one's ability of tar drop, produces a large amount of carbon blacks Crouse's down-stream system is caused fatal influence.
Adapt to the claus process that is rich in the impurity acid gas and in sulphur stove processed catalyst is installed, therefore sulphur stove processed is divided into burning zone, catalytic section and rear.The reaction effect of burning zone directly has influence on life of catalyst and conversion ratio in the catalytic section, is related to the success or failure of process system.Therefore require sulfur burner processed to have higher adaptability, anticlogging ability is stronger, and the flame modeling requirement is higher, and the space utilization degree is higher.Therefore need need badly provides a kind of sulfur recovery facility that is rich in impurity acid gas annular space formula burner that is applicable to.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of sulfur recovery facility that is rich in impurity acid gas annular space formula burner that is applicable to.
For solving the problems of the technologies described above, a kind of sulfur recovery facility of the utility model is with annular space formula burner, comprises from outside to inside nested successively air chamber, acid gas chamber, cooling chamber, and the combustion gas chamber; Be provided with fuel gas mixer and combustion chamber in the combustion gas chamber; Cooling chamber inwall and combustion gas cavity outer wall keep the gap; Upwards be provided with the acid gas air deflector that extends vertically whole week of acid gas cavity wall; Upwards be provided with the air deflector that extends vertically whole week of air chamber inwall.
The end cap that is sealed in the combustion gas top of chamber is provided with igniter, visor, and flame detector.
The utility model satisfies the narrow and small requirement in claus process combustion space of being rich in the impurity acid gas by the control to the flame moulding.
The utility model does not have nozzle arrangements by the annular space formula, has removed the risk of tar drop obstruction burner in the acid gas.
The utility model is by the design of open and flat flame, increased the reaction time of impurity in the acid gas, it has been heated up and pyrolysis fully, for its reaction in catalytic section provides primary condition, for the narrow and small burning zone of sulphur stove processed, this characteristic is estimable and requisite.
Description of drawings
Fig. 1 is the structural representation that sulfur recovery facility provided by the utility model is used annular space formula burner.
Among the figure: 1 is air chamber, and 2 is the acid gas chamber, and 3 is cooling chamber, and 4 are the combustion gas chamber, and 5 are capping, and 6 is igniter, and 7 is visor, and 8 is flame detector, and 9 is air deflector, and 10 is the acid gas air deflector, and 11 is fuel gas mixer, and 12 is the combustion chamber.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model comprises air chamber 1, acid gas chamber 2, cooling chamber 3, and combustion gas chamber 4.Be provided with fuel gas mixer 11 and combustion chamber 12 in the combustion gas chamber 4.Upwards be provided with the acid gas air deflector 10 that extends vertically whole week of acid gas chamber 2 inwalls; Upwards be provided with the air deflector 9 that extends vertically whole week of air chamber 1 inwall.Air chamber 1, acid gas chamber 2, cooling chamber 3, and combustion gas chamber 4 is nested successively from outside to inside.Cooling chamber 3 inwalls and combustion gas chamber 4 outer walls keep the gap.4 tops, combustion gas chamber are equipped with end cap 5 by bolt seal, and igniter 6, visor 7 are installed on the end cap 5, and flame detector 8.Air chamber 1 constitutes acid gas burner with acid gas chamber 2, and cooling chamber 3 constitutes the startup burner with combustion gas chamber 4.
The startup burner is made of combustion gas chamber 4 and cooling chamber 3 for startup, intensification and the afterburning of claus oven provide energy.Combustion gas mixes with startup air blender in being installed in combustion gas chamber 4 11 in the combustion gas chamber, forms annular attached wall flame in combustion chamber 12.Combustion chamber 12 inwalls are provided with the specific coatings material, and this coating has higher anti-impact and rinses and high-temperature stability.When cooling chamber 3 is worked in the combustion gas chamber, feed the cooling air and provide protection to combustion gas chamber 4 outer walls.
Acid gas burner is the main device that claus oven is handled sour gas, is made of acid gas chamber 2 and air chamber 1.The air deflector 9 of air through being installed in air chamber 1 end reaches swirl strength M, and the acid gas air deflector 10 of acid gas through being installed in acid gas chamber 2 ends reaches swirl strength N, air and M＜N＜0.6 opposite with the acid gas rotation direction.Acid gas and air burning form open and flat flame, and the size of the subtended angle of open and flat flame and recirculating zone, center is regulated by swirl strength M and N.
