Abstract
The invention discloses a slurry spraying and stirring device for a desulfurization absorption tower, and relates to a stirring device for replacing a laterally-fed stirrer for a desulfurization spraying absorption tower. The device comprises a spraying pipe (1) and a spraying throat pipe (2), wherein a suction port (3) which extends outwards and is bell-mouthed is formed at one end of the spraying throat pipe (2); and the nozzle end of the spraying pipe (1) is fixed at the suction port (3) of the spraying throat pipe (2) through a support plate (4) which is axially arranged. The device has the advantages of simple structure, high reliability, low failure rate, manufacturing cost, using cost and maintenance cost, and the like, and can partially or completely replace the laterally-fed stirrer for the desulfurization absorption tower.
Description
Technical field
The present invention relates to a kind of agitating device that is used to replace desulfurization fountain absorption tower side-feeding mixer.
Background technology
Desulfuration absorbing tower is to use physics and chemical method, removes sulfur dioxide in flue gas (SO
2) device or structures.
In multiple desulfuration absorbing tower; It is the fountain absorption tower that one type of absorption tower is arranged; Its groundwork process is to utilize slurry circulating pump will absorb slurries to be transported to the spraying layer that is made up of a plurality of nozzles; Form intensive atomization slurry spray district after absorbing the atomizer ejection of slurries by spraying layer, slurries contact with flue gas in the atomizing spray district, absorb the SO in the flue gas in contact process
2Deng pernicious gas, accomplish flue gas desulfurization, slurries descend slowly and lightly in the stock tank of bottom, absorption tower along inside, absorption tower.
Oxidation wind is used in desulfurization: desulfurization is also claimed oxidation air with oxidation wind, is that the oxidation air that equipment such as oxidation fan provide is transported in the pressure absorption tower slurries, for slurries provide oxygen, with the SO in the slurries
2, H
2SO
3, SO
3 2-Deng being oxidized to SO
4 2-And with slurries in Ca
2+Reaction forms CaSO
42H
2O.The oxidation air source of the gas has various ways.
Desulfuration absorbing tower is used side-feeding mixer: side-feeding mixer is the agitator that gets into from container side.Be that physics character, chemical property, capacity, stirring purpose according to different medium selected corresponding agitator, wall gets into desulfuration absorbing tower from the absorption tower with side-feeding mixer.Its effect is to prevent absorption tower slurries deposition and impel the slurries uniformity.
Because the side-feeding mixer that uses at present needs drive unit to drive, both increase construction costs and also improved use and maintenance cost, also can influence normal the startup when stopping transport because of the slurries deposition on the absorption tower.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of desulfuration absorbing tower to use the slurries jet agitation device; The high potential energy slurries that utilize the collection of desulfuration absorbing tower slurries gathering system are as spraying slurries; In course of injection, the slurries around the suction inlet are sucked and shift the central area, absorption tower onto and reach the stirring purpose, thereby replace the function of side-feeding mixer.
Technical solution of the present invention is: it comprises playpipe and sprays trunnion that spray trunnion one end and be provided with the suction inlet that outside expansion is bell mouth shape, the spout end of playpipe is fixed on the suction inlet place of spraying trunnion through the gripper shoe of axial setting.
Technique effect of the present invention is: it have simple in structure, reliability is high, fault rate is low, cost is low, the operation and maintenance low cost and other advantages, it can partially or completely substitute desulfuration absorbing tower and use side-feeding mixer.
Description of drawings
Fig. 1 is a perspective view of the present invention;
Fig. 2 is the structural representation that partly cuts open of the present invention.
The specific embodiment
As illustrated in fig. 1 and 2, it comprises playpipe 1 and sprays trunnion 2 that spray trunnion 2 one ends and be provided with the suction inlet 3 that outside expansion is bell mouth shape, the spout end of playpipe 1 is fixed on suction inlet 3 places of spraying trunnion 2 through the gripper shoe 4 of axial setting.
Said playpipe 1 is the pipe body with injection trunnion 2, and the two concentric is fixed.
Said gripper shoe 4 is " ten " word cross-like and is fixed in the whole tube chamber that sprays trunnion 1.
The present invention directly is fixed on the absorption tower wall 5 through playpipe 1; The high potential energy slurries that utilize desulfuration absorbing tower slurries gathering system to collect spray from playpipe 1 as jetting fluid; Suction inlet 3 slurries on every side that in course of injection, will spray trunnion 2 suck and shift onto the central area, absorption tower;, reach the purpose of stirring.
Be specially: high velocity slurry flow self-injection pipe 1 sprays into and sprays trunnion 2; Spraying trunnion 2 places generation negative pressure; Spray trunnion 2 and be communicated with suction inlet 3, the slurries in the stock tank of absorption tower are inhaled at suction inlet 3 places, and the slurry stream of suction can prevent suction inlet zone slurries deposition.In spraying trunnion 2, mix with the high velocity slurry flow of playpipe 1 ejection; Mixed slurry stream is by spraying trunnion 2 outlet ejections, and the slurries flow after the ejection has stirring action, and slurries are mixed; Sufficient reacting, thorough can prevent the slurries deposition simultaneously.
The present invention has following advantage:
1, can be used to replace the desulfuration absorbing tower side-feeding mixer.
2, can be energy-conservation, reduce the desulfurization plant power consumption rate.
3, replace the absorption tower side-feeding mixer, stopped desulfuration absorbing tower side-feeding mixer paddle, reductor, motor wearing and tearing, thereby reduced maintenance cost.
4, can reduce the absorption tower construction costs.
5, cooperate rational desulfuration absorbing tower rinse-system after replacing the absorption tower side-feeding mixer, start (jacking-type and side-feeding mixer when desulfuration absorbing tower is stopped transport, can cause slurries deposit cause agitator to be difficult to startup) because of the influence of slurries deposition in the time of can avoiding stopping transport on the absorption tower.
