Abstract
The invention belongs to sulfur recovery technology in the petrochemical and coal chemical industries and provides a burner of a tail gas burning furnace of a sulfur recovery device, which mainly comprises a burner body, a burning flame path, a gas gun (1), a primary air inlet (2) and an ignition gun (9), wherein the burning flame path and the gas gun (1) are positioned in the burner; primary airin a swirling flow enters the burning flame path to be mixed and burnt with gas sprayed out from the gas gun (1) and high-temperature smoke generated during burning is sprayed into a furnace hearth inform of high speed swirling flow; a tail gas inlet (4) is arranged on the burner, a tail gas path and the burning flame path are arranged independently, tail gases enter an interlayer of the body ofthe burner from the top part of the burner and are directly sprayed into the furnace hearth by a group of spraying pipes which are concentric with the burning flame path and are arranged around a lining of the burning flame path, and secondary air is sprayed out along the front end of an interlayer between the tail gas spraying pipes and an outer sleeve pipe to be immediately mixed and burnt withthe tail gases in the furnace hearth of the burning furnace; and at the same time, the secondary air is sprayed out in form of a swirling flow to be mixed and burnt with the tail gases.
Description
Technical field
The invention belongs to the sulphur recovery technology of petrochemical industry and Coal Chemical Industry industry, mainly propose a kind of burner of tail gas burning furnace of sulfur recovery facility.
Background technology
Along with industry such as the petrochemical industry of China and natural gas, Coal Chemical Industry obtain high speed development.The treating capacity of sulfur-containing compound sharply increases thereupon in sour crude oil processing capacity, sulfur-containing gas treating capacity and the coalification industrial process.Because the raising of the level of crude oil processing and the middle-eastern crude that processing contains high-sulfur are more and more, and the high load capacity of device is produced continuously, require sulfur recovery facility necessary reliable, a whole set of sulfur recovery facility reliability of operation can and select for use high-quality equipment to be improved by good technological design.Economic in addition in addition growth makes relevant gas sweetening and sulphur recovery technology become more and more important with the strictness of environmental requirement.Along with the continuous deterioration of global environmental pollution situation, country is more and more higher to the requirement of pollutant emission, thereby the efficient operation of sulfur recovery facility is particularly important.
The sulfur recovery facility tail gas burning furnace is as remaining H in the sour gas incinerator smoke
2S burning of gas carrier, tail gas stove furnace temperature require with it mated burner a certain amount of fuel gas that burns to keep furnace temperature, to such an extent as to remaining H generally about 650 ℃
2S gas is completely oxidized to SO
2After drain in the atmosphere again.And common tail gas burning burner adopts intensification fuel and fuel to enter from burner with combustion air more, tail gas enters from the incinerator body of heater, and adopt a traditional air distribution structure, will certainly shorten the effective time of staying of tail gas in burner hearth like this, cause the pyroreaction time short, and make tail gas fully not react, burn not exclusively.
Summary of the invention
Its main purpose of burner of tail gas burning furnace of the sulfur recovery facility that the present invention proposes is to improve H
2The oxidation effectiveness of S gas fully reacts the toxic gas in the tail gas, (with remaining H
2S gas is completely oxidized to SO
2) the raising environmental-protecting performance.
Another object of the present invention is the structural design by the optimization burner, thereby simplifies the furnace binding of tail gas burning furnace, makes its structure more be tending towards simply reducing cost, and making Operation and Maintenance more convenient.
The present invention adopts following technical proposals to finish its invention task: a kind of burner of tail gas burning furnace of sulfur recovery facility mainly includes burner body, is positioned at the burning quirk of burner and gas gun, primary air inlet and burning torch; At the primary air inlet airstream deflector that is made of one group of vane type eddy current deflector is set and makes primary air become swirling flow to enter the burning quirk, spray into burner hearth with high speed swirling flow form with the Device in Gas mixed combustion of gas gun ejection and the high-temperature flue gas that burning is produced; Gas inlet is arranged on the burner and is provided with exhaust gas channel and burning quirk are independent respectively, tail gas enters in the interlayer of burner body from the burner top, through concentric with the burning quirk and directly spray in the burner hearth of incinerator around one group of playpipe of fire trough liner setting, auxiliary air and tail gas is with the concentric jacket structured incinerator burner hearth that enters, and promptly auxiliary air sprays from import along the interlayer front end between tail gas playpipe and the outer tube immediately and tail gas mixed combustion in the incinerator burner hearth; Be provided with the swirling flow flow deflector in the auxiliary air outlet simultaneously, make the form ejection and tail gas mixed combustion of auxiliary air with swirling flow.
In the structural design of the present invention, gas inlet is arranged on burner body and enters the burner interlayer from the burner top, through concentric with fire trough and directly spray into the incinerator burner hearth around one group of playpipe of fire trough liner setting, does not influence the burning of main fuel gas; Contact with burning quirk outer wall in the flow process simultaneously, play the purpose of preheating; Tail gas and auxiliary air adopt unique sandwich directly to spray in the burner hearth, can make that tail gas mixes with auxiliary air fully, evenly, oxidation thoroughly, this part gas plays the effect to the cooling of incinerator lining effectively equably around the fire trough liner simultaneously.Primary air enters the fuel gas mixed combustion of fire trough and fuel gas spray gun ejection with swirling flow, and the high-temperature flue gas of burning sprays into the incinerator burner hearth with high speed swirling flow form, and the flue gas of the whole burner hearth of disturbance burns fully pernicious gas; Auxiliary air sprays the mixability of having strengthened air and tail gas in the swirling flow mode, makes its reaction more abundant.
The present invention adopts tail gas is entered by the burner interlayer, has effectively simplified the furnace binding of incinerator, and its cost is reduced.
