Technical field
The invention belongs to boiler, relate in particular to the energy-conservation hot air boiler of a kind of thermal efficiency height, environmental protection.
Background technology
In the prior art, the heating of rural area warmhouse booth, raising canopy, if adopt hot-water heating, mounting cost is high, often adopts the fire tube hot air boiler to warm oneself.This hot air boiler is simple in structure, and burning condition is poor, and boiler thermal output is low, and exhaust gas temperature is high, wastes energy, and the deashing amount is big, is unfavorable for promoting the use of.
In order to address the above problem; On July 30th, 2008; China utility model patent Granted publication CN 201093729Y discloses a kind of hot-blast stove, is included in the bottom and is provided with and fuels mouth, the body of heater of ash hole, upper of furnace body and be provided with the chimney interface, and body of heater thorax inherence is fueled and is provided with fire grate between mouth, the ash hole; Said body of heater is made up of shell and interior cover and is formed the cavity interlayer; Be provided with the some heating tubes that are uniformly distributed with along the axial inwall of interior cover, the heating tube two ends are fixedly connected with interior cover inwall respectively and communicate with the cavity interlayer, and sidewall of the furnace body is provided with the hot-blast outlet that is communicated with the cavity interlayer near the top.Be provided with the air outlet that is communicated with the cavity interlayer in corresponding fire grate position.This kind boiler causes fire box temperature low because low temperature return air directly gets into from burner hearth of the furnace body, and imperfect combustion CO gets into smoke exhaust pipe and burns once more, and exhaust gas temperature is high, and fuel economy is still lower.
Summary of the invention
The problem that the present invention is directed to the prior art existence is improved, and provides a kind of rational in infrastructure, and heat transfer rate is fast, and the thermal efficiency is high, and energy-saving effect is remarkable, easy to operate energy-conservation hot air boiler.
The present invention adopts following technical scheme for realizing above-mentioned purpose: a kind of energy-conservation hot air boiler, comprise inside and outside body of heater, be provided with in the bottom of external furnace body fuel mouthful, ash hole, air outlet and air outlet; The external air blast of air outlet wherein, the external air-introduced machine of air outlet; Return air inlet is arranged at the top of external furnace body, and return air inlet takes back airduct; The top of external furnace body the chimney interface arranged; Dust Storage Room, static pressure bellows, fire grate and the burner hearth that is communicated with ash hole arranged at said inner furnace body bottom; Open a plurality of small through hole on the furnace wall of burner hearth, have a benefit fan housing to cover fully around the appearance of furnace wall; Above-mentioned static pressure bellows be one by multistage rectangular tube or rectangular bend, the end to end each other toroidal cavity body that forms, the outside portion of static pressure bellows is opened an air admission hole and is communicated with said air outlet, the top drilling of static pressure bellows communicates with said benefit fan housing bottom; The inside portion of static pressure bellows or bottom opening communicate with burner hearth from said fire grate bottom; Said external furnace body constitutes the first cavity interlayer with inner furnace body bottom appearance, static pressure bellows top and benefit fan housing appearance; The first cavity interlayer takes back the air port; Said inner furnace body top is the stove tube, and stove tube top connects the chimney interface; The inwall of stove tube is provided with the heating tube group that level is uniformly distributed with; Leaning on the air blast pusher side; Have by the inboard on external furnace body top, the second cavity interlayer that left outer wall and left horizontal baffle was separated out of stove tube, the 4th cavity interlayer that left outer wall and left horizontal baffle was separated out by the inboard on external furnace body top and top thereof, stove tube is arranged; The 4th cavity interlayer is communicated with return air inlet; Leaning on the air inducing pusher side, the 3rd cavity interlayer that right outer wall and right horizontal baffle was separated out by the inboard on external furnace body top and top thereof, stove tube is being arranged; Above-mentioned left horizontal baffle is arranged on the middle part of heating tube group left port, and the heating tube group is divided into two halves up and down; Above-mentioned right horizontal baffle is arranged on the bottom of heating tube group right output port, and the first cavity interlayer of heating tube group and below is isolated.
The used fuel of the present invention can be coal, living beings.
The course of work of the present invention is: ash hole is shut, mouthful fueled to burner hearth through fueling, ignite; Make fuel combustion, when normal combustion heats up, open air blast; Wind gets into the static pressure bellows from air blast; In the static pressure bellows, most of wind gets into burner hearth from the inside portion or the bottom opening of static pressure bellows through fire grate, and fuel is constantly burnt.Few part wind is realized mending wind through mending fan housing layering entering burner hearth from the top drilling of static pressure bellows, and imperfect combustion CO is fully burned.High-temperature flue gas after the burning rises to heating tube group district along the stove tube and carries out heat exchange; Flue-gas temperature is lowered, and the flue gas after the cooling is discharged through external chimney with the chimney interface at stove tube top.Meanwhile; The course of work of hot-air system of the present invention is: under the effect of air-introduced machine; Return air gets into the 4th cavity interlayer through return air inlet, all presses through the buffering of the 4th cavity mezzanine space, and wind carries out the following current heat exchange through first heating tube group and becomes hot blast to enter into the 3rd cavity interlayer; Hot blast is all pressed through the buffering of the 3rd cavity mezzanine space again, and hot blast carries out countercurrent flow through second heating tube group again and improves wind-warm syndrome, enters into the 4th cavity interlayer again; Hot blast improves wind-warm syndrome around the radiant heat that inner furnace body bottom appearance continues to absorb burner hearth on one side in the 4th cavity mezzanine space, and the part hot blast adds again and vulcanizes fan housing simultaneously; At last, the high temperature wind in the 4th cavity mezzanine space is delivered to the heating of warmhouse booth or raising canopy through air-introduced machine and airduct.
The present invention compares with prior art, and it is reasonable to have a compact conformation, and heat transfer rate is fast, and the thermal efficiency is high, reduces the deashing number of times, and is easy to operate, and characteristics such as long service life can satisfy the requirement that remote intensification or short distance heat up.The present invention mainly tries out in purposes such as warmhouse booth, aquaculture, factory building, residential building, oven dry.Reduce expense 60% than hot water space heating boiler is installed, energy-conservation more than 40%, the air outlet temperature is at 60-190 ℃, and heating area is 100-1000 square metres.
