Description
Technical field
This utility model is related to a kind of air stove, especially a kind of indirect hot air stove with cold air preheating.
Background technology
Air stove as thermal power machinery starts extensively application in late 1970s in China, and it is in many industries
The regeneration product of electric heat source and conventional vapor power heat source is become.Air stove is divided into the high purification air stove of direct-type and indirect type
Air stove, indirect hot air stove is primarily adapted for use in dried material and does not allow to be contaminated, or is applied to the relatively low thermal sensitivity of temperature
Dry materials.Indirect hot air stove combustion gas is in combustor（Body of heater）Interior abundant burning, the hot-air after burning, through heat exchanger,
Heat is given fresh cold air, fresh air temperature can be made to reach more than 1000 degree.Existing indirect hot air stove body of heater
Can be expelled directly out after the heat smoke of generation and heat exchanger heat-shift, now heat smoke becomes cold flue gas, the temperature of cold flue gas
It is general to be re-used for seeming that temperature is relatively low, effect is bad with heat exchanger contact heat-exchanging between 60-130 °, but it is expelled directly out
Seem again and extremely waste, to the insufficient of fuel thermal energy conversion.
Chinese patent Authorization Notice No. is CN202868979U, and authorized announcement date is the utility model patent of 2013.04.10
Patent discloses a kind of heat exchanger pressure-bearing type air stove, constitutes including the combustor being arranged in hot-blast furnace body and by heat exchanger
Heat Room；The combustor and the horizontally adjacent setting of Heat Room, the indoor heat exchanger of the heat exchange is arranged in pressure-bearing type, described
Heat Room is provided with the flue gas blower fan in the indoor heat suction Heat Room of burning.The design structure is simple, easy to make,
Under the suction of flue gas blower fan, produced heat can be by heat transfer principle, heating heat exchanger pipeline so as to carry out in combustor
Heat exchange.But, the flue gas of combustor is expelled directly out, and it is insufficient that fuel thermal energy is converted, and economic benefit is low.
The content of the invention
The purpose of this utility model is to overcome exist in indirect hot air stove in prior art the cold smoke with uniform temperature
Gas is expelled directly out causes fuel thermal energy to convert insufficient problem, there is provided a kind of simple structure, fuel thermal energy high conversion rate
Indirect hot air stove with cold air preheating.
To realize object above, technical solution of the present utility model is：A kind of indirect type with cold air preheating
Air stove, including body of heater and heat exchange box, are provided with heat exchanger in the heat exchange box, heat exchanger top is provided with hot-blast outlet, changes
Hot device is connected by air inlet pipe with aerator, it is characterised in that：Water tank is additionally provided with the heat exchange box, air inlet pipe passes through water tank
It is connected with heat exchanger, fume pipe is connected through water tank with the exhanst gas outlet of heat exchange box outer wall.
The fume pipe includes tube head, and tube head is cavity-like, and at least two separate escape pipes are connected with after tube head,
Escape pipe afterbody is connected with exhanst gas outlet.
The beneficial effects of the utility model are：
1st, the design includes body of heater and heat exchange box, and water tank is additionally provided with the heat exchange box, and air inlet pipe passes through water tank and changes
Hot device is connected, and after the heat smoke produced in body of heater carries out heat exchange with heat exchanger, heat smoke becomes cold flue gas, due to fume pipe
It is connected with the exhanst gas outlet of heat exchange box outer wall through water tank, cold flue gas will be remaining during exhanst gas outlet is reached through fume pipe
Water in heat transfer feed-tank, the water of water tank will be preheated after being heated to the cold air in air inlet pipe, and cold air is obtained
Heat exchanger is entered after certain intensification to continue to heat, and is finally given hot-air and is discharged via hot-blast outlet, the design simple structure, energy
Cold air is preheated using cold flue gas, takes full advantage of the heat energy of fuel.
2nd, fume pipe includes tube head in the design, and tube head is cavity-like, be connected with after tube head at least two it is separate
Escape pipe, escape pipe afterbody is connected with exhanst gas outlet, and such design causes cold flue gas to discharge via a plurality of escape pipe, escape pipe
More, the area of heat exchange is bigger, and heat just can be transmitted as far as possible cold flue gas the water in feed-tank, heat utilization rate
It is high.
