Abstract
The invention relates to an airtight automatic-oxygen-supply, twinbridge-smoke and smoke-drum energy-saving hot blast stove. The hot blast stove comprises a stove body, a dust chamber, a chimney and a blower. The hot blast stove further comprises a waste heat recoverer, an induced draft fan and a temperature controller except the stove body, the dust chamber, the chimney and the blower. The stove body is connected with the blower, the induced draft fan and the dust chamber. The dust chamber is connected with the waste heat recoverer and the chimney, and the blower is connected with the temperature controller. The hot blast stove is in a double-smoke and double-air structure, heat transfer area is large, and heat exchange is sufficient. Waste heat is recovered by the recoverer, and temperature of cold-air preheat can be increased by about 10 DEG C. Fuel is saved by more than half than the conventional stove, smoke discharge is reduced, and mounting is convenient. Temperature stability is high, temperature difference is about +/- 3 DEG C, and temperature can be flexibly adjusted. Labor is economized, and the service life is long.

2, energy consumption large (many consumptions about 40%), soot discharge capacity is large, environmental pollution weight;
3, labor intensive, needs frequently to manage stove fire (needing for average about 20 minutes to manage stove fire, refuelling or minimizing fuel, temperature required to ensure);
4, service life is short.Air-introduced machine adopts air draught mode, and stove inner bag slightly defect just can
Soot is sucked in hot blast, thus affects tea leaf quality
Summary of the invention
The present invention relates to one

Described restoration of lower stack is also provided with ash discharge frame and firedoor frame.
Described smoke box outer setting fin II.
Hot-blast stove of the present invention is primarily of chimney, and cigarette backhaul body of heater crossed by one deck cigarette wind adverse current, the following current of one deck cigarette wind, doube bridge, and waste-heat recoverer forms.Branch designs, easy accessibility.Cold wind, by recover, blasts body of heater by blower fan from outer layers towards inner layers and heats, finally bloat supply wind devices.The part (dividing ectonexine plume by smoke baffle plate) of inner bag plume blasted outer smoke stratification from internal layer by playing smoke pipe (gap bridge) by air blast, be back to inner bag by upper smoke pipe (upper gap bridge) of crossing again to top, after last two-layer plume mixing, enter waste-heat recoverer.Control cigarette speed and smoke which by chimney and temperature control system simultaneously, can control temperature flexibly.
The present invention has following characteristics compared with prior art:
1, the two stratification of wind of two cigarette is adopted, one deck cigarette wind adverse current, one deck cigarette wind following current (existing stove uses a pair adverse current or two pairs of adverse currents mostly), gap bridge mode is adopted between outer plume and internal layer plume, passed a bridge under inner bag lower furnace top is provided with smoke pipe 13(), cross cigarette area and rationally make plume shunt ratio rationally smooth and easy; Cross on inner bag top is provided with equally on smoke pipe 6(and pass a bridge), plume is refluxed.
2, outer plume controls air blast air blast by temperature control and to be pressed into from internal layer plume and to carry out heat exchange, automatically can control that press-in smoke which is how many, speed according to wind-warm syndrome; Burner hearth is airtight, adopts temperature controller to control air blast and provides oxygen needed for hearth combustion, both combinations can reach the artificial effect in temperature constant energy-saving (average 2 hours manage a stove fire, and actual temperature and setting temperature requiredly to differ ± 3 DEG C within).
3, be provided with smoke box: dead room sedimentation dedusting, can exhaust gas heat exchange be carried out, energy-conserving and environment-protective simultaneously.
4, cold wind sucks from stove top, carries out preheating simultaneously, make full use of using waste heat from tail gas with chimney, then can carry out multilayer circulation heat exchange by blower fan press-in body of heater, and finally discharging provides heating equipment.Plume, after two-layer smoke stratification heat exchange, converges with stove top and is discharged by chimney, carries out waste heat recovery and dedusting in waste-heat recoverer simultaneously.
Its advantage is:
1, energy-efficient.Adopt two cigarette, two stratification of wind structure, heat transfer area is large, and heat exchange is abundant; Adopt recover by waste heat recovery, cold wind preheating can be heightened about 10 DEG C.More over half than traditional stove fuel saving, reduce soot discharge, easy for installation.
2, temperature stability is good.Adopt temperature controller automatically to control plume and smoke which, reach equalized temperature stablizing effect, about temperature deviation ± 3 DEG C, and temperature can be adjusted flexibly.
3, less manpower.2 hours only need manage a stove fire, save artificial three parts two than existing stove.
4, the life-span is long.Adopt air blast form to provide hot blast (market adopts air draught type mostly), also can continue to use even if body of heater inner bag burns defectiveness, the life-span is longer than stove on the market of market.
