Abstract
The utility model relates to a sludge drying device for a circulating fluidized bed boiler, and belongs to the field of thermoelectric equipment. The boiler is connected with an economizer through a pipeline; the economizer is connected with a multi-pipe dust collector through a pipeline; the multi-pipe dust collector is connected with a drying fan through a pipeline; the drying fan is connected with a sludge dryer through a pipeline; a sludge drying tower is arranged at the upper end of the sludge dryer; a wet sludge hopper is arranged on one side of the sludge drying tower; the bottom of the wet sludge hopper is connected with the sludge drying tower through a sludge feeder; the top of the sludge drying tower is connected with a dry sludge collector through a pipeline; and the gas outlet of the dry sludge collector is connected with an electrostatic dust collector, a boiler induced-draft fan and a chimney in turn through a pipeline. By arranging the sludge drying device, 85 percent of wet sludge can be quickly dried, and a mixed burning effect is achieved; and the transportation cost and labor cost of manual airing are saved, space and time required by airing are saved, and the requirement of environment friendliness is met.
Description
Technical field
The utility model relates to a kind of circular fluid bed sludge drying device, belongs to the thermal power unit field.
Background technology
There is the qualification of handling mud the boiler factory, can realize that the burning of mixing of refuses such as mud is handled.But the mud that transports is 85% wet basis mostly, and water cut is bigger, the journey flow-like.Mix behind the coal because high humidity usually occurs stopping up phenomenons such as crusher, trommel screen, cause coal ineffective, but also can cause the ineffective disconnected coal phenomenon of coal under the coal bunker, influence boiler and normally move.Place outdoor airing to deposit and to cause environmental pollution, do not meet environmental regulations.
Summary of the invention
Deficiency according to prior art; The technical problem that the utility model will solve is: a kind of circular fluid bed sludge drying device is provided; The device that utilizes existing resource that mud is carried out quick mummification, mud can reach and in time mix the burning condition after the mummification, does not influence the operation of boiler.
The utility model solves the technical scheme that its technical problem adopted: a kind of circular fluid bed sludge drying device is provided; Comprise boiler and economizer; Boiler connects economizer through pipeline; It is characterized in that also comprising: multi-tube dust cleaner, drying air fan, sludge dryer, drying sludge tower, wet bucket, mud feeding machine, dewatered sludge scoop, electrostatic precipitator, boiler induced-draft fan and chimney, economizer connects multi-tube dust cleaner through pipeline, and multi-tube dust cleaner connects drying air fan through pipeline; Drying air fan connects sludge dryer through pipeline; The sludge dryer upper end is equipped with the drying sludge tower, and drying sludge tower one side is provided with wet bucket, and wet bucket bottom links to each other with the drying sludge tower through the mud feeding machine; The drying sludge top of tower connects the dewatered sludge scoop through pipeline, and the pneumatic outlet of dewatered sludge scoop connects electrostatic precipitator boiler induced-draft fan and chimney successively through pipeline.
Said wet bucket lower end is provided with kickoff.
Said dewatered sludge scoop material outlet place is provided with dried mud and discharges machine.
Said wet bucket top is provided with electronic cover plate.
High-temperature flue gas is through multi-tube dust cleaner part dedusting (flue dust is sent into ash-transmission system by the ash conveying spiral machine) behind back-end ductwork flue gas and the economizer; Send into sludge dryer by drying air fan, get into the drying sludge tower again, wet mud is sent into the drying sludge tower from wet bucket by the mud feeding machine; In the drying sludge tower by the flue gas mummification; Dried mud and flue gas get into dried mud scoop, and flue gas returns the preceding flue collector of electric precipitator, and dried mud is got rid of machine and the output of dump machine by dried mud.
The beneficial effect of the utility model is: through installing additional of sludge drying device, can be so that 85% wet basis mud, and flash baking reaches and mixes the burning effect.Save transportation, the human cost of artificial airing, saved airing requisite space and time, reached environmental requirement.
