Description
Technical field the utility model relates to a kind of heater.
Background technology is present, is all using hot-blast stove in many fields of industrial or agricultural and people's life.Traditional hot-blast stove structure is: establish heat-insulation layer by the housing exterior that barrel-type casing and top blind flange are formed, the shell inner bottom part is provided with fire grate, and the housing of air port (also being breast hole) above the fire grate that the housing below this fire grate is provided with the band door is provided with the coal filling hole of band door.Be provided with above the fire grate it is covered on the burning chamber shell that certain interval is arranged between also following and the shell, on this combustion chamber top board wall, be provided with some through holes, be fixed with vertical pyrotechnics pipe lower end on it, pyrotechnics pipe upper end is fixed on the orifice plate below the smoke-box, and the smoke exhaust pipe that is connected with smoke-box passes the cover plate upper end and is connected with atmosphere.Be respectively equipped with the cold wind import and the hot-blast outlet that are connected with heating clamber on shell, this heating clamber is by the folded space of shell, combustion chamber and orifice plate.The weak point of above-mentioned hot-blast stove is: adopt traditional efficient of heat exchange pattern own just very low, and easy dust again in the pyrotechnics pipe, make the thermal efficiency just lower, for reaching certain heating load, hot-blast stove bulky makes equipment investment expense height; While exhaust gas temperature height.Fuel consumption is many, the many contaminated environment of the Dust Capacity of discharging; Its used fuel is fat coal in addition, and the fuel scope of application is too narrow.
The summary of the invention the purpose of this utility model is to provide that a kind of energy consumption is low, the thermal efficiency is high, pollution is little, equipment and operating cost is low, fuel is applied widely energy-efficient heat blower.The utility model also includes the shell of being made up of barrel-type casing and top blind flange, and heat-insulation layer is established in its outside; The shell inner bottom part is provided with fire grate, and the shell below this fire grate is provided with the air port (also being breast hole) of band door, and the shell above the fire grate is provided with the coal filling hole of band door; Be provided with burning chamber shell above the fire grate, be provided with some through holes on this combustion chamber top board, its central through hole is provided with the smoke exhaust pipe that the lower end is fixed thereon, and this smoke exhaust pipe passes the cover plate upper end and is connected with atmosphere.For reducing the dust of discharging, preferably smoke exhaust pipe is two sections, be provided with dust-settling compartment between them, this dust-settling compartment be the diameter that constitutes by metallic plate greater than the smoke exhaust pipe diameter and the chamber of two openings is up and down arranged, its upper end open links to each other with epimere smoke exhaust pipe lower end, its lower ending opening links to each other with the upper end of hypomere smoke exhaust pipe, and the dust-settling compartment lower case is back taper, the dust that settles down is glided along the conical surface, fall on the fire grate below the combustion chamber, so that remove by smoke exhaust pipe.Establish conical fair water cone on the top of hypomere smoke exhaust pipe again, it can change the flow direction of flue gas, makes it to enter dust-settling compartment from the fair water cone side, increases heat-transfer effect first, can reduce the discharge capacity of dust simultaneously again.Be provided with some through holes around the top board central through hole of above-mentioned combustion chamber, all be fixed with heat pipe on it, its underpart is positioned at the combustion chamber, and top is positioned at heating clamber.This heating clamber is the folded space of shell, combustion chamber and smoke exhaust pipe.For improving heat exchanger effectiveness, the heat pipe that is positioned at heating clamber is provided with radiating fin.Be provided with the cold wind import that is connected with heating clamber in shell upper in addition, be provided with the hot-blast outlet that is connected with heating clamber at outer casing underpart.When the fuel combustion on the fire grate, heat pipe absorbs the heat energy that fuel discharges by the endotherm section that is positioned at the combustion chamber, and the heat transfer medium in it is vaporized rapidly, makes it to enter radiating segment, carries out heat exchange by radiating segment and air again, with the air heat in the heating clamber.The cold wind import is provided with blower fan, and its cold wind that is blown into (natural wind or return air) is gone out heated air displacement in the heating clamber, so the air of being discharged by hot-blast outlet is hot blast.For making full use of heat energy, the cold air elder generation preheating that preferably will enter heating clamber is promptly established toroidal membrane in the dust-settling compartment bottom once, and its central through hole links to each other with the hypomere smoke exhaust pipe, and the neighboring links to each other with shell, and the space on this dividing plate top is a preheating chamber.On dividing plate, be provided with the through hole that enters for preheated air.Establish through hole on the dust settler upper wall, which is provided with the preheating heat pipe, its underpart is positioned at dust-settling compartment, and top is positioned at preheating chamber, and it is identical with above-mentioned heat pipe operation principle, and different is that this preheating heat pipe is to absorb entrained heat in the flue gas.So the cold air that is blown into by blower fan enters following heating clamber after the heat preheating by the release of preheating heat pipe earlier again, can make full use of heat energy like this, improves overall thermal efficient.The cold air only of for this reason setting up defences in preheating chamber directly enters the deflector of heating clamber without preheating, and this deflector also helps the exchange of heat simultaneously.In addition establish combustion-supporting airduct at outer casing underpart, its upper end is connected with heating clamber, and the lower end is connected with air compartment below the fire grate, and establishes the magnetic valve of controlling the air quantity size on the combustion-supporting airduct.The warm-air supply combustion zone that can utilize body of heater self to produce like this, to the fuel preheating, can not only improve the thermal efficiency like this and can save air blast again, can also enlarge the scope of application of fuel simultaneously, make bituminous coal, anthracite, brown coal, wooden fuel and other conventional solid fuel all can use.On above-mentioned heat blower, also be provided with nozzle, be preferably uniform 4-8 cover.Water jet one end of this nozzle is positioned at heating clamber, and water inlet one end links to each other with the feed pipe that is located at enclosure, and this feed pipe is provided with magnetic valve.When having a power failure or blower fan when breaking down, magnetic valve is opened automatically, and the water of nozzle ejection can make hot pipe cooling; When operation at ordinary times, the humidity that the water of nozzle ejection can be regulated hot blast.
The utility model has following advantage compared to existing technology:
1, therefore adopting heat pipes for heat transfer efficient improved the thermal efficiency of entire equipment more than 95%, reduced energy resource consumption, greatly reduces operating cost; Also can reduce the volume of entire equipment simultaneously, reduce investment cost of equipment.
2, exhaust gas temperature is low, almost do not have dust in the cigarette, so environmental pollution is very little.
3, fuel is applied widely, and solid fuel commonly used all can use.
4, heat pipe is difficult for dust, can keep heat exchange effect efficiently for a long time.
5,60-240 ℃ hot blast can be provided.
