Abstract
The utility model relates to industrial drying and heating equipment, in particular to a double-stage separation efficient clean fluidized bed coal hot air furnace. The double-stage separation efficient clean fluidized bed coal hot air furnace is provided with a furnace body and is characterized in that a front fire barrier and a rear fire barrier in the furnace body divide an inner cavity of the furnace body into a combustion chamber, a smoke sedimentation chamber and a heat exchange chamber, the top ends of the two fire barriers are disconnected with the top of the furnace body by a certain distance, a combined grid separator is arranged above the first fire barrier, and a smoke channel is formed above the second fire barrier; an air heat exchanger is arranged in the heat exchange chamber, an equipressure air bellow is arranged below the combustion chamber, and a coal feeding pipe is arranged at the front end of the furnace body and exactly faces the combustion chamber.
Description
Technical field
The utility model relates to industrially drying heating equipment, and especially a kind of twin-stage separates high effect cleaning fluidized bed burned-coal hot-blast stove.
Background technology
Existing industrial hot blast heating equipment is mostly chain grate furnace in conjunction with air heat exchanger structure, is mainly horizontal type level and installs.Chain grate furnace exists burning insufficient, the difficulty of slagging tap, and can not burning inferior coal, and heat exchanger easily leaks out with the existence of chain grate furnace air outlet joint portion, the drawback such as collapse, and easy-to-clean ash not.Entire arrangement floor space is large, and steel consumption is higher, and split arranges that radiation loss is also larger, and overall thermal efficiency is on the low side.
Summary of the invention
The purpose of this utility model will solve existing hot air heating equipment exactly, can not burning inferior coal, and problems such as easily leaking out, collapse, easy-to-clean ash, floor space are not large, and overall thermal efficiency is on the low side, provides a kind of twin-stage to separate high effect cleaning fluidized bed burned-coal hot-blast stove.
Concrete scheme of the present utility model is: twin-stage separates high effect cleaning fluidized bed burned-coal hot-blast stove, there is body of heater, it is characterized in that: before and after being provided with in body of heater, body of heater inner chamber is divided into combustion chamber, fume sedimentation chamber, heat-exchanging chamber by twice firebreak, twice firebreak top all disconnects certain distance with body of heater top, and assembled grating separator is installed above first firebreak, and second firebreak top is exhaust gases passes; And air heat exchanger is installed in heat-exchanging chamber, below combustion chamber, is provided with isobaric bellows, coal-feeding tube is housed just to combustion chamber placement at body of heater front end.
The below of fume sedimentation chamber described in the utility model is provided with ash bucket.
The upper end of air heat exchanger described in the utility model is for entering mouth, and lower end is exhaust opening, and air heat exchanger is provided with cold wind blast pipe and warm air discharge tubes is extended respectively body of heater outside.
In the utility model, adopt fluidized bed combustion, its combustion system is that fire coal is broken into the particle below 10mm, through coal feeder average rate send on burner hearth fluid bed, the high-pressure blast of air blast by isobaric bellows the numerous blast cap apertures from air distribution plate inject burner hearth, the wind of each side's scattering aggregates into " air cushion " picking-up coal grain and furnace charge is the Boiling Combustion of fluidisation state, and coal grain and cinder are pranced up and down in the condition of high temperature, mutually wearing and tearing, collision and cracking, by little and large until burn.
Cup of the present utility model is combustion chamber, fuel produces high-temperature flue gas and enters grid separator after fluidized bed combustion, enter again expansion chamber, flue gas through two-stage separate laggard enter shell and tube air heat exchanger, high-temperature flue gas heats the normal temperature dry air in pipe through superheater tube bundle, be heated to export hot blast after the dry temperature needing, useless flue gas is discharged from stove tail after heat absorption.
The utility model has the advantages that:
1. adopt fluidized bed combustion, have that fuel tolerance is wide, burn-off rate is high, can fire the advantages such as colm.
2. adopt large area assembled grating separator, there is long service life, the advantages such as thick good dedusting effect.
3. adopt expansion chamber to the further sedimentation of flue gas.
4. the utility model structure arranges compactness, arranges rationally, and economical and practical, monolithic construction heat exchange efficiency is high.
5. the convenient electromechanical automatic technology that adopts, easily realizes temperature automatically controlledly, automatically go up coal, automatically adjustment.

Fig. 2 is the view of the A-A of Fig. 1.
In figure: 1-body of heater, 2-coal-feeding tube, 3-combustion chamber, 4-assembled grating separator, 5-fume sedimentation chamber, 6-exhaust gases passes, 7-air heat exchanger, 8-warm air discharge tubes, 9-cold wind blast pipe, 10-second firebreak, 11-ash bucket, 12-first firebreak, the isobaric bellows of 13-.
The specific embodiment
Referring to Fig. 1,2, the utlity model has body of heater 1, particularly: before and after being provided with in body of heater 1, body of heater 1 inner chamber is divided into combustion chamber 3, fume sedimentation chamber 5, heat-exchanging chamber by twice firebreak 12,10, twice firebreak top all disconnects certain distance with body of heater 1 top, and the employing the applicant's of assembled grating separator 4(system patent ZL201120131332.5 is installed above first firebreak 12), second firebreak 10 tops are exhaust gases passes; And air heat exchanger 7 is installed in heat-exchanging chamber, below combustion chamber 3, is provided with isobaric bellows 13, at body of heater 1 front end, coal-feeding tube 2 is housed and just combustion chamber 3 is arranged.
The below of fume sedimentation chamber 5 described in the utility model is provided with ash bucket 11.The upper end of described air heat exchanger is for entering mouth, and lower end is exhaust opening, and air heat exchanger is provided with cold wind blast pipe 9 and warm air discharge tubes 8 is extended respectively body of heater 1 outside.
