Abstract

The utility model relates to a cyclone dust collector for vertical hand-fired boiler used for the dust removal of flue gases of the hand-fired boiler. The dusty gas is reelingly separated by an impeller inducer and is reelingly separated secondly by a small cyclone after entering into the cyclone dust collector, and the separated dust particle is exhausted from a dust falling pipe. The purified flue gas changes the moving direction through an anti-drag impeller, and is exhausted into the atmosphere from a chimney. The structure adopted by the cyclone dust collector solves the problems of the back mixature and the secondary flying of the dusty air flow, and raises the dedusting effect. Thus, the utility model not only reduces the pollution of the atmosphere, but also has the advantages of compact structure, small volume, few floor space and easy installation.

Description

Vertical hand-fired boiler cyclone dust collectors

The utility model relates to a kind of dust-removing device for boiler, particularly with the matching used cyclone dust collectors of vertical hand-fired boiler.

Present vertical hand-fired boiler is intermittent coal, by artificial slagging-off, because the restriction of this body structure of boiler, smoke content has substantially exceeded the permission discharge standard of national regulation, and what the employed cyclone dust collectors of prior art can be up to standard fully is also few in number, in these cyclone dust collectors, the cylindrical shell that has is too high, needs the pipeline of connection long, and the build that has is bigger, steel quantity consumption is more, and the floor space that has is too big.

The purpose of this utility model provides a kind of vertical hand-fired boiler cyclone dust collectors, and it does not need by air-introduced machine, relies on the draft of chimney and the pressure of air blast, flue gas can be discharged smoothly.

The purpose of this utility model is achieved in that it comprises urceolus 10, and the upper and lower end of this urceolus 10 is respectively equipped with air inlet 1 and exhaust outlet 12, the downside of urceolus 10 leaves perforate, and this tapping is sealedly connected with ash tube 8, and its primary structure is, in described urceolus

It also includes shunting rotary-assistance mechanism and impeller inducer 3, and this shunting rotary-assistance mechanism is to be fixed in one by helping spiral cone 4 and shunting cone 2 to be upward and downward, and described impeller inducer 3 is to be installed between the inner ring of the outer ring of shunting cone 2 and urceolus 10,

Have tangent line mouth 5 corresponding to the above-mentioned outer tube wall place of the side direction of spiral cone that helps, whirly 6 is to be fixed on the outer wall of urceolus and by above-mentioned tangent line mouth 5 to communicate with urceolus, the upper end of whirly communicates with the urceolus upper end by exhaust elbow 9, and the lower end of whirly is connected to ash tube 7

Drag reduction impeller 11 promptly at the alternate place that helps spiral cone 4 with exhaust outlet 12, also is equipped with in the upper end of tube inner chamber outside, and the outer ring of this drag reduction impeller is fixed on the inwall of urceolus.

Long-pending plate effect of the present utility model is, after ash-laden gas enters cyclone dust collectors, separates through the rotation separation of impeller inducer and the secondary rotation of whirly, isolated grit is discharged through ash tube, and flue gas after being purified is directly arranged to atmosphere by chimney, and cyclone dust collectors adopt this structure, the back mixing and the secondary fly-up of dust-contained airflow have been solved, improved dust removing effects, not only reduced pollution atmosphere, and compact conformation, volume is little, take up an area of and lack, simple installation, flue gas resistance is little.

The utility model is described in further detail below in conjunction with accompanying drawing,

Fig. 1 is a structural representation of the present utility model,

Fig. 2 helps the spiral cone schematic diagram in the utility model,

Fig. 3 is the above-mentioned vertical view that helps spiral cone,

As shown in Figure 1, ash-laden gas enters from air inlet 1, through the shunting cone 2 with flue gas radially to external shunt, change the rectilinear motion of flue gas into rotatablely moving upwards through impeller inducer 3 again, helping has six to help and revolve helical blade (as Fig. 2, shown in Figure 3) on the spiral cone 4, with the further swing that strengthens flue gas, and dwindled the flow area of flue gases in the urceolus 10 gradually, flue dust is under the effect of centrifugal force and gravity, assemble to the barrel of urceolus 10, along the barrel landing through ash tube 8 to the collection ash can.

Simultaneously in rotary course, the gas that contains a large amount of grits from the nearest part of barrel, enter two of next door along the tangential direction of urceolus 10 through tangent line mouth 5 and be in whirly 6 cylindraceous, flue dust further is rotated separation, and the grit of separating drops down onto in the collection ash can through ash tube 7.In order to strengthen the rotary speed of flue gas in whirly, there is an eccentric distance in the cylinder center of described whirly 6 with respect to the tube hub of ash tube 7.

Purify rotatablely moving of back flue gas in the tube through drag reduction blade 11, become rectilinear motion upwards, reduced the resistance of flue gas, flue gas after being purified enters the top of deduster through exhaust elbow 9 in whirly 6, converge with the air-flow that has purified in the tube, enter chimney by exhaust outlet 12 and drain into atmosphere.
