Abstract
The utility model provides a desulfurization, dust removal and self-cleaning system of a residue-fired boiler, which belongs to the technical field of smoke and dust treatment of a fully furfural residue-fired boiler and mainly aims at solving the problems that shutdown is required for artificially cleaning a smoke and dust mixture after burning of furfural residues in the prior art, and the production efficiency is further affected. The system comprises a desulfurization and dust removal chamber and a dust accumulation pool, and is characterized by further comprising a water injection pipe, a plurality of sedimentation tanks and clear water return pipes, wherein a smoke gas inlet is arranged on one side of the desulfurization and dust removal chamber, and a smoke gas outlet is arranged on the other side of the desulfurization and dust removal chamber; the dust accumulation pool is positioned below the desulfurization and dust removal chamber; the water injection pipe is communicated with the dust accumulation pool; the bottom of each sedimentation tank is shaped like a slope, a clear water drainage port is arranged on one side of each sedimentation tank, one end of each clear water return pipe is connected with the clear water drainage port, and the other end of each clear water return pipe is communicated with the dust accumulation pool; the smoke and dust mixture in the dust accumulation pool is pumped into the sedimentation tanks through a slurry pump; and the water level in the dust accumulation pool is lower than that in each sedimentation tank. Clear water in the sedimentation tanks can be recycled.
Description
Technical field
The utility model belongs to full combustion furfural dregs boiler smoke processing technology field, is specifically related to fire slag boiler desulfurization dedusting self-cleaning system.
Background technology
Dust quantity is large after the furfural dregs burning, and long-pending to a certain extent when the laying dust pond, shutdown is cleared up with regard to needs, and artificial clear pond needs 3-4 people, and two day time, production efficiency is lower, and production cost is high.
Summary of the invention
The purpose of this utility model is to solve the problem that prior art exists, and combustion slag boiler desulfurization dedusting self-cleaning system is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
Combustion slag boiler desulfurization dedusting self-cleaning system comprises desulfurization dust chamber and laying dust pond; It is characterized in that: also comprise water injection pipe, some sedimentation basins and clear water return duct; Described desulfurization dust chamber one side arranges smoke inlet, and opposite side arranges exhanst gas outlet; Described laying dust pond is positioned at the below of desulfurization dust chamber; Described water injection pipe communicates with the laying dust pond; Described sedimentation basin bottom is ramped shaped, and the one side arranges the clear water outlet, and described clear water return duct one end is connected the other end and communicates with the laying dust pond with the clear water outlet; Flue dust mixture in the laying dust pond is by slush pump suction sedimentation basin; The laying dust pool water level is lower than the sedimentation basin water level.
The utility model compared with prior art has following beneficial effect:
1, the injection clear water makes it to become mud in the flue dust mixture because the utility model adopts, and extracts out with slush pump again, has substituted manually, has improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-slush pump; 2-flue gas discharge opening; 3-desulfurization dust chamber; 4-smoke inlet; 5-laying dust pond; 6-clear water return duct; 7-sedimentation basin.
The specific embodiment
As shown in Figure 1, combustion slag boiler desulfurization dedusting self-cleaning system comprises desulfurization dust chamber 3 and laying dust pond 5; Be characterized in: also comprise some sedimentation basins 7 and clear water return duct 6; Described desulfurization dust chamber 3 one sides arrange smoke inlet 4, and opposite side arranges flue gas discharge opening 2; Described laying dust pond 5 is positioned at the below of desulfurization dust chamber 3; Described sedimentation basin bottom is ramped shaped, and the one side arranges the clear water outlet, and described clear water return duct 6 one ends are connected the other end and communicate with the laying dust pond with the clear water outlet; Flue dust mixture in the laying dust pond is by slush pump 1 suction sedimentation basin 7; The laying dust pool water level is lower than the sedimentation basin water level.
Using method:
The utility model designs for the large characteristics of dust quantity after the furfural dregs burning, for time of assurance equipment operation and efficient, reduction human input, reduces the stopping production clearing times.This system connects to a circulatory system to desulfurization dust chamber 3, desilting system, sedimentation basin, clear water return duct.With slush pump the flue dust mixture is extracted into sedimentation basin, carries out natural sediment, clear water and be back to the laying dust pond and continue to use, long-pending to a certain extent the time when the sedimentation basin precipitation, stopping using in this pond, reinstates standby pool.Long-pending full sedimentation basin bleeds off Yu Shuihou, by forklift from the slope one side advance the pond sediment cleaning.
