Abstract
The utility model relates to a dust collecting device of a boiler, and belongs to the field of flue gas purification plants of boilers. The dust collecting device of the boiler comprises a fan, a flue discharge pipeline, a closed reservoir, a spraying device, a motor and a chimney; wherein the closed reservoir is provided with a flue inlet and a flue discharge port, lime water is filled in the reservoir, one end of the flue discharge pipeline is connected with the boiler, the other end of the flue discharge pipeline penetrates through the flue inlet of the closed reservoir to be inserted into space below the liquid level of the lime water, and the flue discharge pipeline is connected with the fan; and the chimney of the boiler is connected onto the flue discharge port of the closed reservoir, and is connected with the spraying device, and the spraying device is connected with the motor. The dust collecting device of the boiler is simple in structure, secondary dust removal can be carried out for harmful substances such as sulfur and nitrogen in soot, then the soot can be exhausted into the atmosphere, and the dust collecting device is energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of dust-removing device for boiler, belongs to the flue purifier of boiler field.
Background technology
Simple scraper-type and the dedusting of medicine formula are all adopted in dedusting in the industry field at present, and cost is high, and dust removing effects is poor, and environmental pollution is serious.Many enterprises carry out tails dedusting during the operate as normal on daytime, discharge white cigarette, and close cleaner for reducing cost night, directly waste gas entered in the atmosphere serious environment pollution.And exhaust gas temperature is high, makes that the service life of chimney is short.
The utility model content
For overcoming the above problems, the utility model provides a kind of dust-removing device for boiler, and cost is low, is suitable for all kinds boiler, good dedusting effect, and the height of reduction chimney reduces exhaust gas temperature, prolongs the service life of chimney.
For solving above technical problem, the utility model provides following technical scheme:
A kind of dust-removing device for boiler comprises blower fan, smoke discharging pipe, closed cistern, spray equipment and chimney.
Smoke discharging pipe is connected with blower fan; Smoke discharging pipe one end connects boiler, and the other end is connected to advancing mouth and extending under the liquid level of closed cistern, is limewash in the closed cistern; The outlet flue of closed cistern is connected to chimney through pipeline, and the chimney middle and lower part is equipped with spray equipment.Spray equipment is connected with motor, through motor-driven.
The smoke discharging pipe two ends connect boiler and closed cistern respectively; Tail gas through blower fan is discharged boiler is introduced closed cistern by force; Because smoke discharging pipe stretches into the limewash liquid level below in the closed cistern; Therefore can the sulphur in the boiler exhaust gas and nitrogen the like waste reacted in limewash and precipitate through the limewash in the cistern, reach the purpose of first step desulfurization and dedusting.
The outlet flue of closed cistern is connected to chimney through pipeline; Tail gas behind closed cistern first step desulfurization and dedusting is discharged through pipeline to chimney again; Middle and lower part at chimney is equipped with spray equipment; When tail gas discharged through chimney, the motor-driven spray equipment carried out the second step dust-removal and desulfurizing to tail gas, further strengthened the effect of tail gas clean-up.
The utility model dust-removing device for boiler, simple in structure, can harmful substance such as sulphur, nitrogen in the coal smoke be carried out final dusting, enter in the atmosphere energy-conserving and environment-protective again.
Description of drawings
Fig. 1 is the structural representation of the utility model dust-removing device for boiler;
1, blower fan; 2, smoke discharging pipe; 3, limewash; 4, closed cistern; 5, spray equipment; 6, motor; 7, chimney.
The specific embodiment
As shown in Figure 1, a kind of dust-removing device for boiler comprises blower fan 1, smoke discharging pipe 2, closed cistern 4, spray equipment 5 and chimney 7.
The outlet flue of closed cistern 4 is connected to chimney 7 through pipeline; Tail gas behind closed cistern 4 first step desulfurization and dedustings is discharged through pipeline to chimney 7 again; The spray equipment of installing in the middle and lower part of chimney 75 is when tail gas discharges through chimney 7; 5 pairs of tail gas of motor-driven spray equipment carry out the second step dust-removal and desulfurizing, further strengthen the effect of tail gas clean-up.
The utility model dust-removing device for boiler, simple in structure, can harmful substance such as sulphur, nitrogen in the coal smoke be carried out final dusting, enter in the atmosphere energy-conserving and environment-protective again.
The described specific embodiment of the utility model does not constitute the restriction to the application's scope; Every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to replacement, improvement etc. and all should be included within the protection domain of the utility model.
