Abstract
The invention discloses a spray pipe device for a desulfurizing absorption tower. The spray pipe device comprises a main spray pipeline (1), a plurality of branch pipelines (2) and nozzles (3), wherein a plurality of branch pipeline connectors (6) are uniformly arranged in the main spray pipeline (1); the plurality of branch pipelines (2) are fixedly arranged on the main spray pipeline (1) through the connectors (6); the nozzles (3) are fixedly arranged on the main spray pipeline (1) and the branch pipelines (2) and are in a uniform distribution state; and a desulfurizing liquid enters the branch pipelines (2) through the main spray pipeline (1) and then is sprayed towards flue gas through the nozzles (3). The spray pipe device is simple in structure; the nozzles are uniform in mounting positions and uniform to spray when working, and sulfur dioxide in the flue gas can be fully absorbed; in addition, the used material is good in corrosion resistance; the spray pipe device is relatively light in weight; the spraying pipe device is effectively prevented from being blocked in the use procedure as the nozzles with different shapes are adopted according to different application methods; and the desulfurizing effect is greatly improved.
Description
Technical field
The present invention relates to industrial boiler desulfurizing technique for smoke field, particularly a kind of desulfuration absorbing tower spray pipe device
.
Background technology
The Dual alkali that the sulfur method that Industrial Boiler adopts at present is main and lime stone-gypsum; This this sulfur method is all pass through spray pipe device, by doctor solution spray in flue gas, sulfur dioxide in flue gas is absorbed, spray pipe device is generally arranged in desulfuration absorbing tower, usual spray pipe device part and parcel spray piping, the general high-grade alloy steel material that adopts is made, and the feature of this material is expensive, body is overweight, and corrosion resistance is undesirable; After current used spray pipe device is arranged on absorption tower in addition, spray time, due to nozzle location arrange improper, cause non-uniform spraying, the sulfur dioxide in flue gas can not be fully absorbed, environmental protection standard requirement cannot be reached; Moreover owing to not selecting nozzle according to different sulfur method, clogging have impact on the effect of desulfurization greatly to make nozzle in use occur.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of desulfuration absorbing tower spray pipe device, spray main pipeline has been evenly arranged multiple subtube connector, multiple subtube is fixed on spray main pipeline by connector; Nozzle to be firmly arranged on spray main pipeline and subtube and uniformly distribution, and doctor solution is entered subtube by spray main pipeline and sprayed to flue gas by nozzle; Because nozzle mounting position is even, uniform spraying during work, makes the sulfur dioxide in flue gas to be fully absorbed, and uses material good corrosion resistance in addition and spray pipe device lighter in weight; Moreover use difform nozzle effectively to avoid in use occurring that spray pipe device blocks, and substantially increases desulfurized effect for different usings method.
The technical solution used in the present invention is: a kind of desulfuration absorbing tower spray pipe device, is made up of spray main pipeline, multiple subtube, nozzle; Described spray main pipeline has been evenly arranged multiple subtube connector, and multiple subtube is fixed on spray main pipeline by connector; Described nozzle to be firmly arranged on spray main pipeline and subtube and uniformly distribution; It is characterized in that: described subtube is arranged on spray main pipeline, is arranged in fish-bone state, each subtube becomes the angle of 45-75 degree with spray main pipeline.
Described each subtube becomes vertical with spray main pipeline and fixedly mounts state, and is provided with branched pipe again on each subtube, and branched pipe is vertical with subtube.
Described nozzle is spiral solid-cone (type) nozzle or vortex nozzle.
Described spray main pipeline and subtube are provided with multiple nozzle installing port.
Described spray main pipeline and subtube are 316L stainless-steel pipe.
Described nozzle adopts 316L stainless steel or SIC material to make.
The present invention, structure is simple, and nozzle mounting position is even, and uniform spraying during work, makes the sulfur dioxide in flue gas to be fully absorbed, and uses material good corrosion resistance in addition and spray pipe device lighter in weight; Moreover use difform nozzle effectively to avoid in use occurring that spray pipe device blocks, and substantially increases desulfurized effect for different usings method.

Detailed description of the invention
Embodiment 1:
Known by Fig. 1, a kind of desulfuration absorbing tower spray pipe device, be made up of spray main pipeline 1, multiple subtube 2, nozzle 3; Spray main pipeline 1 has been evenly arranged multiple subtube connector 6, and multiple subtube 2 is fixed on spray main pipeline 1 by connector 6; Spray main pipeline 1 and subtube 2 are provided with multiple nozzle installing port; Nozzle 3 to be firmly arranged on spray main pipeline 1 and subtube 2 and uniformly distribution by nozzle installing port; It is characterized in that: described subtube 2 is arranged on spray main pipeline 1, is arranged in fish-bone state, each subtube 2 and the angle spraying main pipeline 1 one-tenth 45 ~ 75 degree; Nozzle 3 is selected by using method: use spiral solid-cone (type) nozzle when desulfurization uses Dual alkali or sodium alkali; Vortex nozzle is used when desulfurization uses lime-gypsum, magnesium oxide method or lime stone-gypsum; Spray main pipeline 1 is 316L stainless steel pipes with subtube 2; Spiral solid-cone (type) nozzle 3 adopts 316L stainless steel material to make; Vortex nozzle 3 adopts SIC material to make; Spray pipe device is fixed in absorption tower 7 by support 4.During work, doctor solution is entered subtube 2 by spray main pipeline 1 and is sprayed to flue gas by nozzle 3; Because nozzle 3 installation site is even, uniform spraying during work, the sulfur dioxide in flue gas can be fully absorbed, and each part all uses the material of good corrosion resistance in addition, and spray pipe device lighter in weight; Moreover use difform nozzle 3 effectively to avoid in use occurring that spray pipe device blocks, and substantially increases desulfurized effect for different usings method.
Embodiment 2:
Known by Fig. 2, it is another kind of status architecture schematic diagram of the present invention, described subtube 2 is arranged on spray main pipeline 1 by connector 6, each subtube 2 and the vertical fixed installation state of spray main pipeline 1 one-tenth, and branching pipe 5 is provided with again on each subtube 2, branching pipe 5 is vertical with subtube 2, greatly reduce equipment cost by this quantity that can reduce subtube 2 arranged vertically, the position additionally by branching pipe 5 makes the position of nozzle 3 more improve the uniformity of flue gas desulfurization sprinkle.
