Description
Technical field
The present invention relates to coal-fired hot-blast stove technical field, specially a kind of high-efficient hot air furnace.
Background technology
At present, conventional coal-fired hot-blast stove, floor space is big, and the active combustion of burner hearth can not be completely covered in sootfall room
Scope, causes depositing dust not thorough, thus have impact on hot blast efficiency.
The content of the invention
It is an object of the invention to overcome the shortcomings of that there is provided a kind of high-efficient hot air furnace, this efficient hot-air in background technology
Stove, expansion chamber covers the active combustion scope of burner hearth, reduces floor space, improves dustfall efficiency.
To achieve the above object, the present invention provides following technical scheme：A kind of high-efficient hot air furnace, including body of heater, the stove
Body includes burner hearth and is arranged on the exhaust duct of burner hearth sidewall, and the top of the burner hearth is provided with flame-thrower nozzle, the burner hearth and air draft
The lower section of pipe is provided with the sedimentation channel plate that back taper is provided with above expansion chamber, the expansion chamber, between the burner hearth and exhaust duct
Provided with symmetrical above and below, and the upper fireguard and lower fireguard being separated by a certain distance, the entrance top of the exhaust duct is provided with drop
Dirt shutter.
It is preferred that, the distance of the upper fireguard and lower fireguard is the 1/3 of furnace height.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the high-efficient hot air furnace, directly sets expansion chamber below burner hearth and exhaust duct, covers the combustion range of burner hearth, burning
Powdered coal cinder directly enter expansion chamber by settling channel plate, thus improve dustfall efficiency.
2nd, the high-efficient hot air furnace, sets the sedimentation channel plate of back taper above expansion chamber, powdered coal cinder is made in gravity
With lower convenience enter expansion chamber, it is to avoid be deposited on sedimentation channel plate.
3rd, the high-efficient hot air furnace, sets symmetrical above and below between burner hearth and exhaust duct, and the upper gear being separated by a certain distance
Fiery plate and lower fireguard, it is ensured that freeze profile into convolution flame, extend the burning time of coal dust, make coal dust firing fully,
Burning is more thorough.
4th, the high-efficient hot air furnace, depositing dust shutter is set in the entrance top of exhaust duct, is further stopped and is risen with air-flow
Powdered coal cinder, it is fallen into the expansion chamber set below exhaust duct and removed, it is ensured that the hot blast of exhaust duct discharge is cleaner.
5th, the high-efficient hot air furnace, reasonable in design, with small volume, easy to manufacture, cost is low, and working service is convenient,
The advantages of dust-laying effect is notable.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：Fire is kept off on 1- bodies of heater, 2- burner hearths, 3- delivery pipes, 4- flame-thrower nozzles, 5- expansion chambers, 6- sedimentation channel plates, 7-
Fireguard under plate, 8-, 9- depositing dust shutters.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, a kind of high-efficient hot air furnace that the present invention is provided, including body of heater 1, the body of heater 1 is including burner hearth 2 and sets
The exhaust duct 3 in the side wall of burner hearth 2 is put, the top of the burner hearth 2 is provided with flame-thrower nozzle 4, the lower section of the burner hearth 2 and exhaust duct 3
Provided with expansion chamber 5, the top of expansion chamber 5 is provided with the sedimentation channel plate 6 of back taper, is provided between the burner hearth 2 and exhaust duct 4
Symmetrical above and below, and the upper fireguard 7 and lower fireguard 8 being separated by a certain distance, the entrance top of the exhaust duct 4 is provided with depositing dust
Shutter 9.
The distance of the upper fireguard 7 and lower fireguard 8 is the 1/3 of the height of burner hearth 2.
Operation principle：When the high-efficient hot air furnace works, flame is by being arranged on the flame-thrower nozzle 4 of the top of burner hearth 2 of body of heater 1
Into burner hearth 2, due to playing the role of upper fireguard 7 and lower fireguard 8, flame convolution burning in burner hearth 2 is caused, coal is extended
The burning time of powder, make coal dust firing fully, burn it is more thorough；The coal ash that pulverized coal friring is produced is fallen into by settling channel plate 6
Expansion chamber 5 is removed；With air-flow enter exhaust duct 3 hot blast, its carry secretly coal ash due to there is the stop of depositing dust shutter 9,
Expansion chamber 5 is fallen into also by the sedimentation channel plate 6 of the lower section of exhaust duct 3 to be removed, it is achieved that the repeatedly sedimentation to coal ash,
Improve the dustfall efficiency of coal ash, it is ensured that the hot blast of exhaust duct discharge is cleaner.
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art,
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacing, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in this
Within the protection domain of invention.
