Abstract

The utility model discloses a pulse type cyclone washing device of a desulfurization sedimentation basin. The pulse type cyclone washing device of the desulfurization sedimentation basin comprises a sedimentation basin and a vertical shaft, wherein a size channel ditch and a slurry pipeline are arranged at the bottom of the sedimentation basin; a slurry pump is mounted on the slurry pipeline; a support pillar of the vertical shaft is mounted on the vertical shaft; a washing pipeline is mounted around the vertical shaft, and is located inside the sedimentation basin; and a plurality of pulse cyclone nozzles are mounted on the washing pipeline. Through the improvement, the condition of hardening and curing of desulfurization slurry inside the sedimentation basin is greatly improved, so that the problem of influencing the slag discharge effect can be solved well; the normal operation of a desulfurization system can be recovered; desulfurization liquid keeps clean all along; and the normal and safe operation of the desulfurization system can be ensured.

Description

Desulfurization sedimentation basin pulsed rotational flow flushing device
Technical field
The utility model relates to a kind of particularly double alkali method desulfurizing technology of wet desulphurization that is applicable to, and relates in particular to a kind of desulfurization sedimentation basin pulsed rotational flow flushing device.
Background technology
What power plant's wet desulphurization adopted is double alkali method desulfurizing technology, its cardinal principle is to utilize NaOH solution as starting desulfurizing agent, the NaOH solution prepared is squeezed into to desulfurizing tower, absorb the SO2 in flue gas, desulfurization product and Ca(OH) 2 solution reactions, restore NaOH solution and return again circulation desulfurization in desulfurizing tower.The sulphur of taking off is separated out (being desulfurated plaster) with the form of calcium sulfite, calcium sulfate, carries out fully utilizing after processed.
The desulfurization slag treatment system comprises vertical-flow square sedimentation basin and slag stock pump and vacuum dewatering system.The slag stock pump, by the slurry of the desulfurization slag in sedimentation basin suction concentration basin, is transported outward after vacuum belt dewatering system processed.Higher because entering stove coal sulphur content, the sulfur dioxide original concentration all, more than 5000 mg/m3, produces desulfurated plaster every day approximately more than 70 tons.The desulfurization slag slurry easily hardens curing, after moving 3-4 days, has basically piled up full desulfurization slag slurry in sedimentation basin.Due to slag stock pump pump intake in sedimentation basin one side, after desulfurization slag pulpboard knot solidifies, only can lift suction pump entrance a small amount of desulfurization slag on every side starch, the desulfurization slag slurry of other sides can't be extracted out, and space in sedimentation basin is diminished gradually, and settling height shortens, calcium sulfite in doctor solution, calcium sulfate etc. can't precipitate, doctor solution starts by becoming clearly muddy, and the doctor solution that contains lime enters desulfurizing tower, very easily causes nozzle and demister to stop up fouling.Necessary stoppage in transit desulphurization system, after the nozzle of obstruction fouling in harden desulfurization slag slurry and the desulfurizing tower that accumulate in sedimentation basin, demister etc. are cleaned out, can again prepare the operation of doctor solution startup system, have a strong impact on the normal safe operation of desulfurized effect and desulphurization system.
Summary of the invention
The purpose of this utility model is to provide a kind of desulfurization sedimentation basin pulsed rotational flow flushing device, solves desulfurization slag pulpboard knot and solidifies the many difficult problems that affect slag tap effect and the normal operation of system.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of desulfurization sedimentation basin pulsed rotational flow flushing device, comprise sedimentation basin and vertical shaft, the bottom of sedimentation basin is provided with slurry channels ditch, slag slurry pipeline, on slag slurry pipeline, the slag stock pump is installed, the vertical shaft pillar is installed on vertical shaft, it is characterized in that: around vertical shaft, flushing pipe is installed, flushing pipe is positioned at sedimentation basin, and a plurality of pulse rotary flow nozzles are installed on flushing pipe.
According to described desulfurization sedimentation basin pulsed rotational flow flushing device, it is characterized in that: described pulse rotary flow nozzle lays respectively at position, four jiaos of He Meice stage casings, pond.
According to described desulfurization sedimentation basin pulsed rotational flow flushing device, it is characterized in that: in described sedimentation basin, immersible pump is set.
The utility model has the advantages of and be: by above transformation, the interior desulfurization slag pulpboard of sedimentation basin is tied curing situation and is greatly improved, well solved the problem that affects the effect of slagging tap, desulphurization system is recovered normal operation, it is limpid that doctor solution remains, guaranteed the normal and safe operation of desulphurization system.
