Abstract
The invention provides a lower slurry stirring device of a desulfurizing absorption tower. The lower slurry stirring device comprises a slurry output pipe, a slurry delivery pump arranged outside the desulfurizing absorption tower and a slurry distributor submerged in lower slurry of the desulfurizing absorption tower. The slurry output pipe is connected with an inlet of the slurry delivery pump, an outlet of the slurry delivery pump is connected with the slurry distributor, and the supply delivery pump pumps out the lower slurry of the desulfurizing absorption tower and pumps in the lower slurry to the slurry distributor submerged in the lower slurry of the desulfurizing absorption tower. Multi-point slurry discharging is achieved through the slurry distributor, each slurry discharging point stirs slurry around the slurry discharging point, stirring and mixing of the lower slurry of the desulfurizing absorption tower is achieved, sediment formed at the bottom of the desulfurizing absorption tower is greatly reduced or even avoided, up-to-the-standard discharge of boiler exhaust gas and normal production of a company are guaranteed, and labor cost needed by sludge cleaning is reduced.
Description
Technical field
The present invention relates to desulfuration absorbing tower, be specifically related to desulfuration absorbing tower bottom slurry agitating device.
Background technology
The nucleus equipment of boiler flue gas desulfurization is the absorption tower, and the neutralization reaction of sulfur dioxide and NaOH is just finished at this.What my company's desulphurization system adopted is two alkaline process, the amount that lime adds is not easy control, the sodium carbonate that generates in the system is all replaced in the process that generates calcium sulfite, lime sometimes can be excessive, excessive lime reacts with sulfur dioxide in the absorption tower, generate calcium sulfite, be deposited in the absorption tower.In addition, enter the absorption tower owing to when some stove, also having a large amount of cigarette ashes, be deposited on the bottom.Thus, the sediment in the absorption tower can increase gradually, and roughly every operation just needed the cleaning of stopping in one month.Deposit reaches as high as 2 meters, needs at least 2 talentes to clean out.
Summary of the invention
In order to solve the problem of above-mentioned absorption tower inside deposition, the invention provides a kind of desulfuration absorbing tower bottom slurry agitating device.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of desulfuration absorbing tower bottom slurry agitating device, comprise the slurries efferent duct, be arranged at the slurry feeding pump outside the absorption tower and be immersed in the interior pulp distributor of bottom, absorption tower slurries, the slurries efferent duct connects the slurry feeding pump entrance, and the slurry feeding pump outlet connects pulp distributor.
Above-mentioned desulfuration absorbing tower bottom slurry agitating device, described pulp distributor comprise that house steward is connected the some arms that connect with house steward, and a tube end and middle part arrange downward pulp nozzle.
Above-mentioned desulfuration absorbing tower bottom slurry agitating device, described pulp nozzle is 11.
Above-mentioned desulfuration absorbing tower bottom slurry agitating device, the install pipeline thickness of described slurries efferent duct and pulp distributor is at least the wear-resistant liner of 3mm.
Above-mentioned desulfuration absorbing tower bottom slurry agitating device arranges granite slab under the described pulp nozzle.
Above-mentioned desulfuration absorbing tower bottom slurry agitating device, described pulp distributor supports by brace summer, and pulp distributor pipeline and brace summer are fastened by glass wool cloth.
Above-mentioned desulfuration absorbing tower bottom slurry agitating device, described pulp distributor house steward goes back and the cushion gas pipeline communication.
Slurry feeding pump is extracted desulfuration absorbing tower bottom slurries out, and pump into the pulp distributor that is immersed in the slurries of bottom, absorption tower, realize the multiple spot pulp by pulp distributor, each pulp point stirs the slurries around it, cause the stirring of bottom, absorption tower slurries to mix, greatly reduce even avoid forming deposit at the bottom of the absorption tower, guaranteed the qualified discharge of boiler smoke and the normal production of company, the less required labour cost of cleaning mud.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 is A place partial enlarged drawing among Fig. 1.
Fig. 3 is B place partial enlarged drawing among Fig. 1.
Among the figure: 1 house steward, 2 arms, 3 pulp nozzles.
The specific embodiment
As Figure 1-3, desulfuration absorbing tower bottom slurry agitating device comprises the slurries efferent duct, is arranged at the slurry feeding pump outside the absorption tower and is immersed in the interior pulp distributor of bottom, absorption tower slurries, the slurries efferent duct connects the slurry feeding pump entrance, and the slurry feeding pump outlet connects pulp distributor.
Particularly, described pulp distributor comprises that house steward 1 is connected the some arms 2 that connect with house steward, and a tube end and middle part arrange downward pulp nozzle 3.
Particularly, described pulp nozzle is 11.
In order to prolong the service life of pipeline, the install pipeline thickness of described slurries efferent duct and pulp distributor is at least the wear-resistant liner of 3mm.
For fear of the pulp distributor pulp desulfuration absorbing tower inside is damaged, under the described pulp nozzle granite slab is set.
Particularly, described pulp distributor supports by brace summer, and pulp distributor pipeline and brace summer are fastened by glass wool cloth.
Particularly, described pulp distributor house steward goes back and the cushion gas pipeline communication, enables the cushion gas pipeline when pulp spray nozzle clogging or slurry feeding pump fault.
