Abstract
The utility model relates to industrial drying and heating equipment and provides a boiling type hot air blower. The boiling type hot air blower is characterized by comprising a vertical furnace body, wherein an equipressure air box is arranged at the bottom of the furnace body, a combustion chamber is arranged above the equipressure air box in the furnace body, a coal feeding device and a secondary air device are installed on the front side, right opposite to the combustion chamber, of the furnace body, and an air heat exchanger is installed on the top of the furnace body. The boiling type hot air blower is compact in structure, small in occupied area, high in overall heat efficiency and capable of being widely used for food drying and nine heating, inferior coal can be combusted, and coal ash can automatically overflow to be discharged.
Description
Technical field
The utility model relates to industrially drying heating equipment, especially a kind of boiling type air-heater.
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 horizontal type level 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 easily to leak out, collapse, easy-to-clean ash not, the problem such as floor space is large, and overall thermal efficiency is on the low side, provides a kind of boiling type air-heater.
Concrete scheme of the present utility model is: boiling type air-heater, it is characterized in that: there is vertical furnace, the bottom of body of heater is provided with isobaric bellows, and in body of heater, the top of isobaric bellows is combustion chamber, just combustion chamber is provided with to coal feeder and overfire air device in body of heater front; Top at body of heater is provided with air heat exchanger.
For improving the thermal efficiency, heat pipe bundle described in the utility model in air heat exchanger is to adopt blossom type jet pipe, described blossom type jet pipe includes the inner and outer pipe of suit, has densely covered mesh on inner tubal wall, makes the axial arranged groove in some roads on outer tube wall.
For guaranteeing the sufficient space of combustion chamber, be conducive to burn-off rate and improve, prevent air heat exchanger scaling loss, the end face >=3m of the isobaric bellows of the distance from bottom of air heat exchanger described in the utility model.
The utility model is combined into one air heat exchanger and fluidized bed furnace, and vertical adopts the tube bank of blossom type jet pipe composition, is arranged on top, Boiling Combustion chamber, and high-temperature flue gas becomes hot blast by heat pipe by the cold conditions air heat in flowing pipe, supplies with heating device.
The utility model has adopted fluidized bed combustion, automatic overflow deslagging; Blossom type jet pipe can be out of shape by heat of neutralization swelling stress, jet pipe produces and is free air bound rete in tank in heat exchanging process, membrane layer is divided into several piece by plum blossom-shaped, break the integrality of membrane layer, hot air flow penetrates from the jet flow aperture of inner tube, through the multi-faceted reflection of plum blossom-shaped outer tube wall, better play the effect of abundant mixing air uniform heat exchange, improve the thermal efficiency with this.
The utlity model has following characteristics:
1. adopt fluidized bed combustion, have that fuel tolerance is wide, burn-off rate is high, can fire the advantages such as colm;
2. the convenient electromechanical automatic technology that adopts, temperature automatically controlled, automatically goes up coal, and overtemperature stops coal automatically, can effectively prevent that heat pipe from burning;
3. adopt blossom type jet pipe technology, improve heat exchange efficiency;
4. vertical structure, automatic overflow ash discharge;
5. this device arranges compactness, arranges rationally, and the thermal efficiency is high, economical and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that zoomed-in view cuts open in blossom type jet pipe office;
Fig. 3 is the A-A zoomed-in view of Fig. 2.
In figure: 1-air heat exchanger, 2-heat pipe bundle, 3-coal feeder, 4-overfire air device, 5-combustion chamber, 6-isobaric bellows, 7-body of heater, 8-inner tube, 9-outer tube, 10-mesh, 11-groove, 12-cold air inlet, 13-hot-blast outlet.
The specific embodiment
Referring to Fig. 1, the utlity model has vertical furnace, the bottom of body of heater 7 is provided with isobaric bellows 6, and the top of the interior isobaric bellows 6 of body of heater 7 is combustion chamber 5, just combustion chamber 5 is provided with to coal feeder 3 and overfire air device 4 in body of heater 7 fronts; Top at body of heater 7 is provided with air heat exchanger.
End face >=the 3m of the isobaric bellows 6 of the distance from bottom of air heat exchanger 1 described in the present embodiment, is specially 3.5m.
Claims (3)
