Description
Technical field
The utility model relates to warm-air drier field more particularly to a kind of fuel heater unit smoke secondary heat exchangers.
Background technique
Fuel heater unit is mainly matched with tent, solves the heating problem of extremely frigid zones, with provide it is good office,
Living environment.Also it can be used for heating in tent when north of china in winter is camped, can also be used in the fixed barracks of large size and civilian house.
Fuel heater unit has good intensity, high reliablity, service life length, high, capable of washing, corrosion-resistant, the low temperature resistant, low noise of the thermal efficiency etc. excellent
Point.
The thermal efficiency is the main performance index of fuel heater unit, since leaving air temp should not be too low when heating, is generally all answered
It at 70 DEG C or more, is limited by fuel heater unit outer dimension, the heat exchange area of combustion heat exchanger is smaller, causes combustion heat exchanger
Exit gas temperature is higher, and generally between 250 DEG C~290 DEG C, partial heat is discharged into atmosphere with flue gas, causes energy
Source waste, it is therefore desirable to be improved, the heat in flue gas is secondary use.
Utility model content
Based on the above, the application provides a kind of fuel heater unit smoke secondary heat exchanger, warm to solve existing fuel oil
The problem of smoke temperature is excessively high in blower, causes energy waste.
For this purpose, the utility model uses following technical scheme:
A kind of fuel heater unit smoke secondary heat exchanger, including seat, outlet flue heat exchanger tube and smoke under outlet flue heat exchanger tube
Mouthful heat exchanger tube seat of honour, the outlet flue heat exchanger tube setting is under the outlet flue heat exchanger tube seat of honour and outlet flue heat exchanger tube between seat.
As a kind of preferred embodiment of the utility model, under the outlet flue heat exchanger tube seat of honour and the outlet flue heat exchanger tube
Seat is seat under the L shape outlet flue heat exchanger tube seat of honour and L shape outlet flue heat exchanger tube.
As a kind of preferred embodiment of the utility model, the outlet flue heat exchanger tube is kidney-shaped pipe.
As a kind of preferred embodiment of the utility model, the outlet flue heat exchanger tube is elliptic cylindrical shape outlet flue heat exchanger tube.
As a kind of preferred embodiment of the utility model, under the outlet flue heat exchanger tube seat of honour and outlet flue heat exchanger tube seat with
The setting plate of outlet flue heat exchanger tube is provided at the connecting portion of the outlet flue heat exchanger tube.
As a kind of preferred embodiment of the utility model, seat and combustion heat exchanger connecting portion under the outlet flue heat exchanger tube
Place is provided with chimney flange.
The utility model has the following beneficial effects:
Compared with prior art, design adds smoke secondary heat exchanger to the utility model at the outlet flue of warm-air drier,
Its advantage is mainly reflected in that smoke secondary heat exchanger structure is simple, ingenious, reasonable, and resistance is small when flue gas flows in heat exchanger,
Air resistance when flowing through secondary heat exchanger is small, and smoke secondary heat exchanger heat exchange efficiency is high, has sufficiently recycled in flue gas
Waste heat, have the advantages that energy conservation and environmental protection.
Detailed description of the invention
It, below will be to the utility model embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing needed in description is briefly described.
Fig. 1 is a kind of fuel heater unit smoke secondary heat exchanger main view that the utility model embodiment provides；
Fig. 2 is a kind of fuel heater unit smoke secondary heat exchanger side view that the utility model embodiment provides.
Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
It is described in further detail below in conjunction with technical solution of the attached drawing to the utility model embodiment.
As Figure 1-Figure 2, present embodiment provides a kind of fuel heater unit smoke secondary heat exchanger, mainly includes smoke
Seat 1, outlet flue heat exchanger tube 2 and the outlet flue heat exchanger tube seat of honour 3 under mouth heat exchanger tube, the setting of outlet flue heat exchanger tube 2 exchange heat in outlet flue
Under the pipe seat of honour 1 and outlet flue heat exchanger tube between seat 2, since the fuel heater unit smoke secondary heat exchanger tube is for the first time in fuel oil warm wind
Utilization on machine, in order to meet the various needs of fuel heater unit, the fuel heater unit smoke secondary in the utility model is changed
Hot device is made that corresponding change.Seat 3 is equal under the outlet flue heat exchanger tube seat of honour 1 and outlet flue heat exchanger tube first in the utility model
For seat under the L shape outlet flue heat exchanger tube seat of honour and L shape outlet flue heat exchanger tube, so-called L shape, in the utility model more towards
The advantages of seat 3 designs in this way under boots shape, outlet flue heat exchanger tube is that can reduce flue gas changes from a heat exchanger to secondary
Resistance in the outlet flue heat exchanger tube 2 of hot device, similarly, the advantage that the outlet flue heat exchanger tube seat of honour 1 is designed in this way are to reduce
Flue gas from secondary heat exchange pipe to chimney in resistance.General, the outlet flue heat exchanger tube 2 in the utility model is designed as cylindroid
The outlet flue heat exchanger tube 2 of shape, popular says, kidney-shaped pipe is similar to, while effect is resistance when reducing air flowing
It can guarantee enough heat exchange areas, the air for making flue gas and flowing through sufficiently exchanges heat.Preferably, the utility model is changed in outlet flue
Outlet flue heat exchange tube socket is provided under the heat pipe seat of honour 1 and outlet flue heat exchanger tube at the connecting portion of seat 3 and outlet flue heat exchanger tube 2
Sealing plate 4 exchanges heat setting plate 4 by setting outlet flue to guarantee the leakproofness of three's connection, in addition, the utility model is also in smoke
Also be equipped with chimney flange 5 at the connecting portion of seat 3 and the hot device of burningization under mouthful heat exchanger tube, come guarantee flue gas can all into
Enter fuel heater unit smoke secondary heat exchanger, and then be discharged by chimney, as shown, its working principle is that chimney flange 5
With combustion heat exchanger outlet flue flanged joint, the high-temperature flue gas being discharged from combustion heat exchanger outlet flue is under smoke secondary heat exchanger
The chimney of side is entered with flange 5, enters outlet flue heat exchanger tube 2 through seat 3 under the setting plate 4 of outlet flue heat exchanger tube, outlet flue heat exchanger tube,
Enter cigarette through the outlet flue heat exchanger tube seat of honour 1, the setting plate 4 of outlet flue heat exchanger tube with after outdoor cold air (or circulation air) heat exchange
Chimney then drains into atmosphere.
Note that above are only the preferred embodiment and institute's application technology principle of the utility model.Those skilled in the art's meeting
Understand, the utility model is not limited to specific embodiment described here, is able to carry out for a person skilled in the art various bright
