The utility model discloses utilize baking house room air that the air duct inner loop flows in with the combustion chamber heat of accumulation take out of, in fact the air duct of increase is the heat transfer area who has increased heat -exchanging device for heat transfer speed, consequently can improve heat exchange efficiency, fuel saving, environmental protection more.
Description
Technical field
The utility model belongs to heat transmission equipment.
Background technology
Heat transmission equipment is widely used in each industrial circle, is particularly widely applied especially in tobacco flue-curing.At present for the heat transmission equipment of tobacco flue-curing, carry out to adopt the heat exchanger using methyl alcohol, fuel oil, combustion gas etc. as fuel manyly, utilize burner to be heated by the water and air as medium, carry out heat exchange, by drying tobacco by the air in heat transmission equipment and drying room.The deficiency of existing heat transmission equipment shows that heat transfer effect is also not very good, consumes energy more high.
Utility model content
The purpose of this utility model is to provide the heat transmission equipment that a kind of heat transfer effect is better, energy consumption is low.
The technical scheme realizing the utility model object is:
Heat transmission equipment, comprise one end to be provided with the combustion chamber of burner, to be positioned at the exhaust chamber of both sides, described combustion chamber, be provided with some flange-cooled radiating tubes between described combustion chamber and exhaust chamber, be provided with some through described combustion chambers in described combustion chamber and the wireway be communicated with air.
Described wireway divides two rows to be arranged along combustion chamber to narrow by wide from the one end near burner by splayed.
Through described exhaust chamber is provided with and the wireway be communicated with air in described exhaust chamber.
The front portion of described combustion chamber is provided with tubaeform anemostat, and described burner is located at the front end of described tubaeform anemostat.
Described combustion chamber and exhaust chamber all adopt rectangle, and the top of wherein said rectangular type bumer adopts herringbone, and described anemostat is located at the front end of described rectangular type bumer, described radiating tube be arranged in line be located at described rectangular type bumer and rectangle exhaust chamber sidewall between.
Described combustion chamber and exhaust chamber all adopt cylindrical shape, and described anemostat is located on the radial barrel of described throat less chamber, and described radiating tube circularizes cloth and is set between described throat less chamber and the axial barrel of cylindrical shape exhaust chamber.
Described exhaust chamber is provided with blast pipe.
Beneficial effect:
Find after deliberation, why there is heat transfer effect in existing heat transmission equipment not very good, and the reason of the more high deficiency that consumes energy is, the heat that fuel produces in combustion chambers burn process exists the phenomenon that accumulation causes combustion chamber to have burning red in combustion chamber.The utility model adds wireway for this phenomenon in combustion chamber, the drying room room air of wireway internal circulation flow is utilized to be taken out of by the heat accumulated in combustion chamber, the wireway increased is actually the heat exchange area adding heat transmission equipment, accelerate heat transfer rate, therefore heat exchange efficiency can be improved, fuel saving, more environmental protection.The utility model may be used for the industries such as flue-cured tobacco, food, medicinal material, grain, papermaking baking and heating.
Below in conjunction with accompanying drawing, the utility model is described further.

Detailed description of the invention
Embodiment 1
See Fig. 1 to Fig. 3, the heat transmission equipment that the utility model provides, comprise combustion chamber 3 and the exhaust chamber 6 being positioned at both sides, combustion chamber, combustion chamber 3 and exhaust chamber 6 all adopt rectangle, wherein the top 301 of rectangular type bumer 3 adopts herringbone (or arc), be provided with tubaeform anemostat 2 in the front end of rectangular type bumer 3, the front end of tubaeform anemostat 2 is provided with combustor 1, is provided with somely be arranged in line and be with the radiating tube 4 of fin 5 between rectangular type bumer 3 and the sidewall of rectangle exhaust chamber 6; Be provided with some through described combustion chambers 3 in combustion chamber 3 and the wireway 8 be communicated with air, described wireway 8 point two row arranged along combustion chamber 3 to narrow by wide from the one end near combustor 1 by splayed (or alternate manner); Also be provided with aligned (or alternate manner arrangement) through described exhaust chamber in exhaust chamber 6 and the wireway 8 be communicated with air, each exhaust chamber 6 is connected with blast pipe 7.
Combustor 1 is using methyl alcohol as fuel (also can adopt other liquid fuel), during work, the high-temperature combustion gas that combustor 1 burning produces flows through the radiating tube 4 that wireway 8 enters both sides, combustion chamber 3 again, due to wireway 8, point two rows in combustion chamber 3 arrange (also can arrange otherwise) by splayed, make the high-temperature gas basis equalization that front and back radiating tube 4 enters, be conducive to the burning of methyl alcohol and being uniformly distributed of thermal current, the combustion rate of methyl alcohol can reach more than 95 %; Heat exchange is carried out by fin 5 and the air in tobacco flue-curing house after high-temperature gas enters radiating tube 4, partial air in tobacco flue-curing house then carries out heat exchange through wireway 8 and the high-temperature gas in combustion chamber 3, the blower fan F blowing be arranged in tobacco flue-curing house above combustion chamber 3 makes the Indoor Thermal air through heat exchange form convection gas quickening heat exchange, herringbone (or arc) top 301 of combustion chamber 3 is conducive to the heat radiation of combustion chamber 3, the temperature of tobacco leaf improves by hot-air, the moisture in tobacco leaf is constantly evaporated and forms hot and humid gas discharge tobacco flue-curing house.The burning gases completing heat exchange through radiating tube 4 become tail gas and collect at exhaust chamber 6 and discharged by blast pipe 7.
