Description

A kind of Hot Blast Furnace With Heat Pipes
Technical field
The present invention relates to a kind of hot-blast stove, it is characterized in that a kind of novel energy-conserving hot-blast stove.
Background technology
At present, all using hot-blast stove in many fields of wanting industrial or agricultural and people to live, traditional hot-blast stove structure is: establish heat-insulation layer by the housing exterior that barrel-type casing and napex cover plate are formed, the shell inner bottom part is provided with fire grate, the housing of air port (also being breast hole) above the fire grate that housing below this fire grate is provided with the band door is provided with the mouth that adds of being with 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, the smoke exhaust pipe that is connected with smoke-box passes the cover plate upper end and is connected with atmosphere, on shell, be respectively equipped with the cold wind import and the hot-blast outlet that are connected with heating clamber, this heating clamber is by shell, the space that combustion chamber and orifice plate are folded.The weak point of above-mentioned hot-blast stove is: adopt traditional efficient of heat exchange pattern own just very low, and easy again dust in the pyrotechnics pipe, make the thermal efficiency just lower, for reaching certain heating load, hot-blast stove bulky makes equipment investment expense height, exhaust gas temperature height simultaneously.Fuel consumption is many, one day environment of the many pollutions of the Dust Capacity of discharging; Its used fuel is fat coal in addition, and the fuel scope of application is too narrow.
Summary of the invention
The object of the present invention is to provide a kind of energy consumption low, thermal efficiency height pollutes for a short time, and equipment and operating cost are low, the energy-efficient heat blower that fuel is applied widely.The present invention goes out to include 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 is that the diameter that is made of metallic plate is greater than the smoke exhaust pipe diameter and the chamber of two openings is up and down arranged, connect under its upper end open and the 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 by smoke exhaust pipe, so that go out to remove, 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, increase 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 its underpart on it and be positioned at the combustion chamber, top is positioned at heating clamber, and this heating clamber is a shell, the combustion chamber and the folded space of discharging fume.This improves heat and changes efficient, and 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 on the fire grate during fuel combustion, heat pipe absorbs the heat energy that fuel discharges by the heat absorption 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, the air heat in the hot cell of accompanying each other.The cold wind import is provided with its cold wind that is blown into of blower fan (natural wind or return air) heated air in the heating clamber is changed away, 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 last dust settler upper wall, hardship which is provided with the preheating heat pipe, and 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 having existing is that this preheating heat pipe is to absorb entrained heat in the flue gas.So enter following heating clamber again behind the heat founder that the cold air that is blown into by blower fan is discharged by the preheating heat pipe, can make full use of heat energy like this, improve 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, 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.Can utilize body of heater to see the warm-air supply combustion zone that self produces like this, to the fuel preheating, might 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.Also be provided with nozzle on above-mentioned heat blower, Deng is 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 present invention 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, reduced operating cost greatly; Also can reduce the volume of entire equipment simultaneously.Reduced 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.
