Abstract
The utility model relates to an indirectly heating hot-air and hot-water furnace. The utility model comprises an air-water inlet and an outlet, a hot air-water cavity, a furnace door, an ash-draining door, a hearth and a chimney structure. The utility model is characterized in that the hot air-water cavity is positioned at the center and the hot air-water is always packed by the hot fire and hot smoke. A cold air-water inlet and the chimney are arranged on the top, the hot air-water outlet is arranged on the lower part. The cold air-water convects with the hot smoke up-and-down crossly. A flow-changing board and a cockle heat-exchanging steel cover are designed to raise the flow and heat-exchanging area. The utility model has a compact structure with a high heat-exchanging efficiency; the hot air and hot water can be cleanly used at the same time. And the coal, firewood and grass are all used; the utility model can be widely applied to the agriculture, the special breeding, drying devices and life heating.
Description
The utility model relates to a kind of indirect hot air and hot water stove.
Industrialized agriculture, special cultivation, drying materials equipment and heating for residential area etc. all need the hot air and hot water stove of easy economy, but existing technology or can not the hot air and hot water dual-purpose, or complex structure, manufacturing cost height, or heat utilization efficiency is low, operating cost is high, is unfavorable for applying.As the patent No. 01222174.0 disclosed technical pattern complexity; The patent No. 01270015.0 disclosed technology heat-exchange surface is big not enough, and heat exchange process is long not enough, so heat utilization efficiency is also not too high.
The utility model purpose is to provide a kind of hot air and hot water dual-purpose, the big and exchange long flow path of heat-exchange surface, the simple again indirect hot air and hot water stove of structure.
The utility model is realized by following measure: become burner hearth, hot air and hot water chamber, three parts in flue gas chamber with three steel plate enclosures, the hot air and hot water chamber is placed in the middle, and interior two steel cages are made wrinkle shape; Between burner hearth and the flue gas chamber, be communicated with steel pipe between burner hearth middle part and two hot air and hot water chambeies of lower curtate; The cold wind cooling water inlet is located at the body of heater top, and with steel pipe and chimney, top, flue gas chamber is staggered and is communicated with the hot air and hot water chamber, the hot air and hot water outlet is located at heat exchanger tube (hollow bar) under body of heater bottom and the connection; Middle part in the hot air and hot water chamber and heat exchange mouth of pipe place, bottom establish and change the stream plate.
The utility model has the advantages that: cold wind cold water is sent into from the body of heater top, with the terminal heat exchange of flue gas, the heat of discharging chimney is reduced at first.The wind of preheating, water flow through under the effect that changes the stream plate heat exchanger tube and following heat exchanger tube in the burner hearth elongate flow process, and among wrapping up in burner hearth and flue gas chamber all the time.Wrinkle shape heat exchanger plates increases heat exchange area, slows down steel plate rising-heat contracting-cold pressure.Furnace main body is made by three steel cages, and is simple in structure.Hot air and hot water dual-purpose, body of heater place in the drying room, must hot blast with the air blast air blast; Body of heater places in the pond, and fire door stretches out outside the pond, passes through the water hot water that adds just capable of circulation with immersible pump.
Structure of the present utility model and heat exchanging process are provided by following example and accompanying drawing.
A kind of indirect hot air and hot water stove comprises: 1, cold wind cooling water inlet; 2, go up heat exchange box; 3, hot air and hot water chamber; 4, middle heat exchanger tube; 5, following heat exchanger tube; 6, hot air and hot water outlet; 7, fire door; 8, ashpit; 9, cleaning door; 10, wrinkle heat exchange steel cage; 11, burner hearth; 12, ventilating smoke tube; 13, change the stream plate; 14, flue gas chamber; 15, chimney.→ flue gas flow direction ,=＞wind, current direction.
During work, cold wind or cold water are sent into from cold wind cooling water inlet (1) by blower fan or water pump, last heat exchange box (2) at first with the exit gas heat exchange that is about to discharge chimney (15), enter hot air and hot water chamber (3) and change and flow to into middle heat exchanger tube (4) and following heat exchanger tube (5) under the effect that changes stream plate (13), the discharge hot air and hot water exports (6).Coal, bavin, grass flue gas that burner hearth (11) burning produces through about back three ventilating smoke tubes (12) enter flue gas chamber (14), discharge chimney (15) after heat exchange box on process (2) and the cold wind cold water heat exchange that enters at first.Cold wind cold water and is wrapped among the showing tremendous enthusiasm hot cigarette of burner hearth (11) and flue gas chamber (14) from top to bottom all the time fully, further increases heat exchange area by the wrinkle position, elongates heat exchange process by last heat exchanger tube (4) and following heat exchanger tube (5).Hot flue gas from bottom to top, with the staggered heat exchange of cold wind cold water, its temperature is opposite, improves heat exchange efficiency, discharges chimney (15) at last.
Claims (4)
1, a kind of indirect hot air and hot water stove, comprise cold wind cooling water inlet (1), hot air and hot water chamber (3), hot air and hot water outlet (6), fire door (7), ashpit (8), burner hearth (11), chimney (15) structure, it is characterized in that: interior two heat exchange covers (10) are made wrinkle shape.
2, indirect hot air and hot water stove according to claim 1, it is characterized in that cold wind cooling water inlet (1) and chimney (15) are located at the body of heater top, hot air and hot water outlet (6) is located at the body of heater bottom and is communicated with following heat exchanger tube (5), the staggered up and down convection current of cold wind cold water and hot flue gas.
3, indirect hot air and hot water stove according to claim 1 is characterized in that three steel plate enclosures become burner hearth (11), (14) three parts in hot air and hot water chamber (3) and flue gas chamber, and hot air and hot water chamber (3) are placed in the middle.
4, indirect hot air and hot water stove according to claim 1 is characterized in that establishing in the hot air and hot water chamber (3) changing and flows plate (13).
