Abstract
The utility model discloses a desulfurization and ash discharging device at the bottom of a dry flue gas desulfurization absorbing tower, which mainly comprises a screw conveyor, a flange, a double roll crusher, an air locking machine, an ejector and a Roots blower. The double roll crusher comprises a material inlet and a material outlet; the material inlet of the double roll crusher is connected with the screw conveyor through a flange; the material outlet of the double roll crusher is connected with the air locking machine; the ejector is connected with the air locking machine; and one side of the ejector is connected with the outlet pipeline of the Roots blower. The utility model effectively solves the technical problems of effective treatment of desulfurized ash and the recycling utilization, has the advantages of reasonable design, convenient maintenance and low equipment cost, greatly reduces the operating cost of the flue gas desulfurization, and improves the operating interval and the operating environment of the plant.
Description
Technical field
The utility model belongs to the flue gas desulfurization technique field, and particularly a kind of dry flue gas desulphurization that is used for absorbs desulfurization ash exhauster at the bottom of the Tata.
Background technology
At present in the dry flue gas desulphurization process, the ash that falls at the bottom of the absorption Tata is very general, and especially the phenomenon that bulky grain drops at the bottom of tower in the absorption tower is more serious, and handling usually is at the bottom of absorbing Tata the taper ash bucket to be set, regularly carry out ash discharge, be transported to certain place then and stack or landfill.Processing not only can cause secondary pollution like this, and wastes raw material, and increases operating cost, very easily pollutes plant environment.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of dry flue gas desulphurization to absorb desulfurization ash exhauster at the bottom of the Tata.
The purpose of this utility model is achieved through the following technical solutions: desulfurization ash exhauster at the bottom of a kind of dry flue gas desulphurization absorption Tata, and it mainly is made up of conveying worm, flange, double-roll crusher, air locking machine, injector and roots blower; Described double-roll crusher comprises charging aperture and discharging opening, the charging aperture of double-roll crusher links to each other with conveying worm by flange, the discharging opening of double-roll crusher links to each other with air locking machine, and injector links to each other with air locking machine, and injector one side joint is gone into the outlet conduit of roots blower.
The beneficial effects of the utility model are: the utility model has solved effective processing of desulfurization ash and recycling, reasonable in design, easy to maintenance effectively, and equipment cost is low, can reduce the operating cost of flue gas desulfurization greatly, improves between the operation area and plant area's running environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1, tapered ash bucket, 2, flange, 3, conveying worm, 4, charging aperture, 5, double-roll crusher, 6, discharging opening, 7, air locking machine, 8, injector, 9, roots blower, 10, pipeline.
The specific embodiment
Further specify the utility model below in conjunction with the drawings and specific embodiments, it is more obvious that the purpose of this utility model and effect will become.
As shown in Figure 1, the desulfurization ash exhauster mainly was made up of flange 2, conveying worm 3, double-roll crusher 5, air locking machine 7, injector 8 and roots blower 9 at the bottom of dry flue gas desulphurization of the present utility model absorbed Tata.Double-roll crusher 5 comprises charging aperture 4 and discharging opening 6, and flange 2 is movable flange.Conveying worm 3 is installed in the tapered ash bucket bottom at the bottom of the absorption Tata, and the charging aperture 4 of double-roll crusher 5 links to each other with conveying worm 3 by flange 2.The discharging opening 6 of double-roll crusher 5 links to each other with air locking machine 7.Injector 8 links to each other with air locking machine 7, and injector 8 one side joints are gone into the outlet conduit of roots blower 9, and the opposite side pipeline 10 of roots blower 9 inserts absorption tower (venturi upper area, not shown).
When the utility model used, its workflow was:
1, desulfurization ash is delivered to double-roll crusher 5 through the conveying worm 3 of tapered ash bucket 1 bottom and carries out fragmentation, and the 8mm desulfurization ash that broken back grain diameter is not more than enters air locking machine 7, and the desulfurization ash by air locking machine 7 enters injector 8.
2, injector 8 one side joints have the outlet conduit of roots blower 9, and roots blower 9 bloats the wind of enough pressure and carries through the dilute phase strength, by roots blower 9 opposite side pipelines 10 the desulfurization ash is returned and sends into the absorption tower, and the desulfurization ash is taken away by flue gas again.
3, at conveying worm 3 outlet(discharge) flanges 2 places a movable blind flange is installed, increase a urgent ash discharging hole (250 * 400mm), be connected to the ground annex with pipe, so that under the situation that system can't normally move, realize urgent ash discharge.
Claims (2)
1. a dry flue gas desulphurization absorbs desulfurization ash exhauster at the bottom of the Tata, it is characterized in that it mainly is made up of conveying worm, flange, double-roll crusher, air locking machine, injector and roots blower; Described double-roll crusher comprises charging aperture and discharging opening, the charging aperture of double-roll crusher links to each other with conveying worm by flange, the discharging opening of double-roll crusher links to each other with air locking machine, and injector links to each other with air locking machine, and injector one side joint is gone into the outlet conduit of roots blower.
2. according to desulfurization ash exhauster at the bottom of the described dry flue gas desulphurization absorption of claim 1 Tata, it is characterized in that described flange is movable flange.
