Description

Energy-saving hot-air boiler

Technical field

The invention belongs to boiler, relate in particular to that a kind of thermal efficiency is high, the energy-saving hot-air boiler of environmental protection.

Background technology

In 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 high fume temperature wastes energy, and the deashing amount is large, is unfavorable for promoting the use of.

in order to address the above problem, on July 30th, 2008, Chinese utility model patent Granted publication CN 201093729Y discloses a kind of hot-blast stove, being included in the bottom is provided with and fuels mouth, the body of heater of ash hole, upper of furnace body is provided with the chimney interface, mouth is fueled in body of heater thorax inherence, be provided with fire grate between ash hole, described body of heater is comprised of shell and inner sleeve and forms the cavity interlayer, be provided with some uniform heating tubes along the axial inwall of inner sleeve, the heating tube two ends are fixedly connected with the inner sleeve inwall respectively and communicate with the cavity interlayer, 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 in corresponding fire grate position the air outlet that is communicated with the cavity interlayer.This kind boiler causes fire box temperature low because low temperature return air directly enters from burner hearth of the furnace body, and imperfect combustion CO enters smoke exhaust pipe and again burns, and high fume temperature, fuel economy are 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-saving hot-air boiler.

The present invention for achieving the above object, by the following technical solutions: a kind of energy-saving 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 chimney interface is arranged at the top of external furnace body; Dust Storage Room, static pressure bellows, fire grate and the burner hearth that is communicated with ash hole arranged at described inner furnace body bottom; Open a plurality of small through hole on the furnace wall of burner hearth, the appearance surrounding of furnace wall has a benefit fan housing to cover fully; Above-mentioned static pressure bellows be one by the multistage rectangular tube, the end to end toroidal cavity body that forms each other, the outside portion of static pressure bellows is opened an air admission hole and is communicated with described air outlet, the top drilling of static pressure bellows communicates with described benefit fan housing bottom; The inside portion of static pressure bellows or bottom opening communicate with burner hearth bottom described fire grate; Described external furnace body and inner furnace body bottom appearance, static pressure bellows top and mend and consist of the first cavity interlayer together with the fan housing appearance; The first cavity interlayer picks out the air port; Described inner furnace body top is the stove cylinder, and stove cylinder top connects the chimney interface; The inwall of stove cylinder is provided with the uniform heating tube group of level; By the air blast pusher side, inboard, the left outside wall of stove cylinder and the second cavity interlayer that left horizontal baffle is separated out by part on external furnace body are arranged, inboard and top, the left outside wall of stove cylinder and the 4th cavity interlayer that left horizontal baffle is separated out by part on external furnace body are arranged; The 4th cavity interlayer is communicated with return air inlet; By the air inducing pusher side, inboard and top, the right outside wall of stove cylinder and the 3rd cavity interlayer that right horizontal baffle is separated out by part on external furnace body are 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 the up and down two halves; Above-mentioned right horizontal baffle is arranged on the bottom of heating tube group right output port, with the first cavity interlayer isolation of heating tube group and below.

The present invention's fuel used can be coal, living beings.

The course of work of the present invention is: ash hole is shut, mouthful fuel to burner hearth by fueling, ignite, make fuel combustion, when normal combustion heats up, open air blast, wind enters the static pressure bellows from air blast, in the static pressure bellows, most of wind enters burner hearth from inside portion or the bottom opening of static pressure bellows by fire grate, and fuel is constantly burnt.Small part wind enters burner hearth realization benefit wind from the top drilling of static pressure bellows by mending the fan housing layering, and imperfect combustion CO is fully burned.High-temperature flue gas after burning rises to heating tube group district along the stove cylinder and carries out heat exchange; Flue-gas temperature is lowered, and the flue gas after cooling is discharged by external chimney with the chimney interface at stove cylinder top.Meanwhile, the course of work of hot-air system of the present invention is: under the effect of air-introduced machine, return air enters 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, then enters into the 4th cavity interlayer; Hot air ring 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 warm air in the 4th cavity mezzanine space is delivered to the heating of warmhouse booth or raising canopy through air-introduced machine and airduct.

Compared to the prior art the present invention has a compact conformation reasonable, and heat transfer rate is fast, and the thermal efficiency is high, reduces the deashing number of times, easy to operate, and the 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.Than hot water space heating boiler cost reduction 60% is installed, energy-conservation more than 40%, the air outlet temperature is at 60-190 ℃, and heating area is 100-1000 square metres.
