Abstract
The utility model relates to a desulfurization tower bottom jet mixing system, which is arranged at the bottom of a desulfurization tower, and comprises a jet head, spoilers and a slag discharge pipe, wherein a plurality of spoilers are spirally arranged along he circumferential direction of the inner side of a desulfurization tower body, and the jet head is arranged towards the spoilers; and the slag discharge pipe penetrates through the desulfurization tower body, and an inlet end of the slag discharge pipe is arranged in the middle of the desulfurization tower body and discharges desulfurizing liquid and sulfur slag. According to the characteristics of the desulfurizing liquid and the sulfur slag, combined with years of practical experience in engineering, a novel desulfurization tower capable of desulfurizing and discharging the slag smoothly at the bottom is designed, accordingly, the technical problems that the desulfurization and slag discharge at the bottom of the desulfurization tower is not smooth, and pipelines and water pumps are easily blocked by long-time accumulation are solved, the mixing effect is good, the labor is saved, the service time is long, the structure is compact, and the production cost is low.
Description
Technical field
The utility model relates to environmental protection technical field, relates in particular at the bottom of a kind of desulfurizing tower tower the jet mixing system.
Background technology
Flue gas desulfurization---remove sulphur in flue gas and the process of compound, mainly refer to SO, SO2 in flue gas.To reach environmental requirement.
Double alkali method desulfurizing adopts soda ash to absorb SO2, the lime reducing/regenerating, and after regeneration, absorbent recycles.Doctor solution adopts the outer circulation absorption pattern, and the doctor solution that has absorbed SO2 flows into regenerated reactor, carries out regenerative response with new limewash, and reacted slurries flow into precipitation regenerated reactor precipitation.Upper liquid in circulatory pool after regeneration and precipitation is squeezed into desulfurizing tower by circulating pump and is recycled.Along with the long-play of desulphurization system and the problem of operation, and the part flue dust in flue gas enters into doctor solution, and the grey quantity of slag in desulfurizing tower in doctor solution can increase.Bottom traditional desulfurizing tower, majority does not have agitating device, and part has the angle-inserting type mixer at Ta Bishang.When there is no agitating device, desulfurizing tower bottom doctor solution stirs not quite, and the settling amount of lime-ash is larger, and time one length easily hardens, and the grey quantity of slag constantly increases, and can make the wearing and tearing of water circulating pump strengthen, and affects the operation of desulphurization system.Adopt the angle-inserting type mixer can temporarily solve the problem of tower bottom lime-ash sedimentation, but the sealing of mixer and tower wall and maintenance all have problems.
The utility model content
The purpose of this utility model be to provide a kind of efficient, economical and practical, mixing effect is good, save power, jet mixing system at the bottom of the low desulfurizing tower tower of service time length, compact conformation, production cost.
For solving the problems of the technologies described above, the utility model provides at the bottom of a kind of desulfurizing tower tower the jet mixing system, be arranged on bottom the desulfurizing tower body, described jet mixing system comprises jet head, spoiler and scum pipe, described spoiler is a plurality of, arranges in the shape of a spiral along desulfurizing tower body inner circumferential, and described jet head is towards deflector, described scum pipe pass the desulfurizing tower body, the arrival end of scum pipe is arranged on the middle part of desulfurizing tower body and doctor solution and sulphur slag is got rid of.
The utility model improves to be had, and also is provided with circulating pump outside described desulfurizing tower body, and described circulating pump is connected with the jet head, and doctor solution is delivered to the jet head.
The utility model improves to be had, and described spoiler is arranged on desulfurizing tower body inner circumferential uniformly and equidistantly.
The beneficial effects of the utility model are: for the characteristic of doctor solution in desulfurizing tower and sulphur slag, and combination practical engineering experience for many years, the bottom desulfurization deslagging of the new structure of designing is desulfurizing tower smoothly, effectively solved desulfurizing tower bottom desulfurization slag deslagging not smooth, long-time technical problem of piling up easy blocking pipe and water pump, mixing effect is good, save power, service time length, compact conformation, production cost low.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
With reference to accompanying drawing 1 and accompanying drawing 2, the utility model shown in accompanying drawing provides at the bottom of a kind of desulfurizing tower tower the jet mixing system, comprise desulfurizing tower body 1 and be arranged on the jet mixing system of desulfurizing tower body 1 bottom, described jet mixing system comprises jet head 2, spoiler 3 and scum pipe 4, described spoiler 3 is a plurality of, arrange in the shape of a spiral along desulfurizing tower body 1 inner circumferential, described jet head 2 is towards spoiler 3, described scum pipe 4 pass desulfurizing tower body 1, the arrival end of scum pipe 4 is arranged on the middle part of desulfurizing tower body 1 and doctor solution and sulphur slag is got rid of.
In the present embodiment, the setting of spoiler has certain angle, gradient and length, and concrete parameter and number needs will be configured according to the model of desulfurizing tower.
In the present embodiment, described jet head 2, spoiler and scum pipe 4 and desulfurizing tower inside all need to do preservative treatment, to reduce the corrosion of doctor solution, extend working time, and increase the service life of whole desulfurizing tower.
In the present embodiment, described spoiler 3 is arranged on desulfurizing tower body 1 inner circumferential uniformly and equidistantly, and the eddy flow better effects if of the doctor solution that makes is set uniformly and equidistantly, and the spoiler of specific quantity can be set as required.
By the jet mixing system is set at the bottom of the desulfurizing tower tower, can effectively solves the problem that the desulfurization slag deposition is stopped up at the bottom of the desulfurizing tower tower, and can solve the problems such as the sealing that has angle-inserting type mixer and tower wall now and maintenance.Guarantee the continuous and steady operation of desulphurization system.
At the bottom of the desulfurizing tower tower, the jet mixing system mainly is comprised of jet head 2, spoiler and scum pipe 4 three parts, and angle, length, gradient and the quantity of the position of appropriate design jet head 2 and spoiler, to reach the eddy flow state of doctor solution and sulphur slag at the bottom of tower, satisfy the requirement of deslagging.
By using at the bottom of the desulfurizing tower tower jet mixing system, can effectively satisfy the needs that efflux of desulfurization slag, also save the power that stirs under the prerequisite of the stable operation that has guaranteed desulphurization system, and reduced the problem such as maintenance of equipment
