Abstract
The utility model relates to a coal -burning air heater, including the hot -blast furnace body, the export of hot -blast furnace body has connected gradually deposit room, heat exchanger, chimney, be equipped with vertical last baffle in the deposit room and reach baffle down, separate into the communicating space of two parts with the deposit room, be equipped with hot exchange pipe in the heat exchanger, hot exchange pipe communicates with each other with the chimney. The utility model discloses a hot -blast furnace is equipped with the deposit room between being connected with heat exchanger, enable dust particle in the flue gas and carry on effectually subsiding and filtering, through the reentrant heat exchanger of filtration purification's flue gas, has prolonged heat exchanger's life.
Description
Technical field
This utility model relates to a kind of coal-fired hot-blast stove.
Background technology
Current coal-fired hot-blast stove kind is a lot of, but Problems existing and defect are too many, and outstanding behaviours is in the following aspects: one is that the consumption of coal is too big；Two is unreasonable structure, the high-temperature flue gas of combustor do not have any block be just directly entered heat exchanger, make the too early scaling loss of heat exchanger；The letter that three is traditional connects air stove all without sedimentation filtration device, combustor flue gas out is carried substantial amounts of grit secretly and is directly entered heat exchanger, little granule and light dirt thing are exhausted directly in air, easy contaminated air, unfavorable environmental protection, bulky grain and the just accumulation of weight dirt thing in a heat exchanger, greatly affect the thermal efficiency, unfavorable energy-conservation.
Summary of the invention
The purpose of this utility model is in that to overcome the problem existing for above-mentioned air stove, it is provided that a kind of coal-fired hot-blast stove that grit can be made to carry out effectively sedimentation and filtration.
The purpose of this utility model is achieved in that a kind of coal-fired hot-blast stove, including air stove body, the outlet of described air stove body is connected with expansion chamber, heat exchanger, chimney in turn, is provided with vertical upper spacer and lower clapboard, expansion chamber is divided into the space that two parts communicate in described expansion chamber；Being provided with heat-exchange tube in described heat exchanger, described heat-exchange tube communicates with chimney.
Further, described heat exchanger includes upper and lower smoke chamber and the vertical heat-exchange tube placed, described upper smoke chamber is connected with expansion chamber outlet, the upper end of described heat-exchange tube is all connected with upper smoke chamber, the lower end of described heat-exchange tube is all connected with lower smoke chamber, is provided with and arranges heat-exchange tubes by every two and carry out intersecting the dividing plate separated in described upper and lower smoke chamber.
Further, it is provided with ashpit bottom described expansion chamber.
Further, it is provided with ashpit bottom described lower smoke chamber.
Further, described air stove body is connected to combustion fan.
Further, described chimney is connected to smoke exhaust fan.
Air stove of the present utility model is provided with expansion chamber between heat exchanger is connected, and the grit in flue gas can be made to carry out effectively sedimentation and filter, enter back into heat exchanger through the flue gas of filtration, purification, extend the service life of heat exchanger.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the structural representation of coal-fired hot-blast stove.
Legend: 1. combustion fan, 2. air stove body, 3. expansion chamber, 4. upper spacer, 5. ashpit, 6. lower clapboard, 7. descends smoke chamber, 8. dividing plate, 9. goes up smoke chamber, 10. heat exchanger, 11. heat-exchange tubes, 12. chimneys, 13. smoke exhaust fans.
Detailed description of the invention: this utility model, not by the restriction of following embodiment, can determine specific embodiment according to the technical solution of the utility model and practical situation.
Embodiment: as shown in Figure 1, a kind of coal-fired hot-blast stove, including air stove body 2, air stove body 2 is connected to combustion fan, air stove body 2 outlet is connected with expansion chamber 3, heat exchanger 10, chimney 11 in turn, it is provided with vertical upper spacer 4 and lower clapboard 6 in expansion chamber 3, expansion chamber 3 is divided into the space that two parts communicate；Heat exchanger 10 includes upper and lower smoke chamber 9,7 and the vertical heat-exchange tube 11 placed, upper smoke chamber 9 is connected with expansion chamber 3 outlet, the upper end of heat-exchange tube 11 is all connected with upper smoke chamber 9, the lower end of heat-exchange tube 11 is all connected with lower smoke chamber 7, being provided with in upper and lower smoke chamber 9,7 and arrange heat-exchange tubes 10 by every two and carry out intersecting the dividing plate 8 separated, the bottom of expansion chamber 3 and lower smoke chamber 7 is equipped with ashpit 5.Heat-exchange tube 11 communicates with chimney 12, and chimney 12 is connected to smoke exhaust fan 13.
Flue gas after air stove body 2 burning initially enters expansion chamber 3, heat exchanger 10 is entered back into after dust is precipitated by expansion chamber 3, flue gas through heat-exchange tube 11 and in the direction of the arrow upper and lower stroke four times or more times, by the heat exchange as much as possible of the heat in flue gas, last flue gas is discharged from chimney 12.
Flue gas is when expansion chamber 3, and the particulate matter in flue gas is settled by expansion chamber, and crock has also been filtered by expansion chamber 3, is regularly purged from the ashpit 5 below expansion chamber 3, thus having purified the discharge of flue gas, extends the service life of heat exchanger 10.Additionally, heat-exchange tube 11 vertical, the granule in flue dust easily falls, again clearing out from the ashpit 5 bottom lower smoke chamber 7, another has purified the discharge of flue gas, makes heat-exchange tube 11 inwall not hang crock, improve the thermal efficiency, be a kind of energy-saving and environment-friendly New-type hot-air furnace.
Above technical characteristic is only embodiment of the present utility model, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
