Description
Technical field
The invention belongs to agricultural product are heated, are dried the firing equipment field providing heated dry air and in particular to one kind is provided with
The heat-exchange device of mixing bunker.
Background technology
Heating in agricultural production, be dehydrated, drying is conventional technique, needs frequently dry using being provided that in technical process
The firing equipment of hot-air.The heat exchanger of existing firing equipment has 16 groups of radiating tubes, and in a heat exchanger in a row longitudinally
Arrange one by one, as shown in Figure 1.Radiating tube in heat exchanger and radiating fin arrange more tight, air in interchange channel
Relatively short by the time of interchange channel, cause rate of heat exchange not high, and it is all from top to bottom that water steams in the radiating tube of place
Co-flow, the temperature potential of radiating tube must form the low situation of relative superiority or inferiority, result in the interchange channel upper, middle and lower layer of air temperature difference
Excessive, it is unfavorable for the abundant exchange of heat.Therefore also there is combustion heat exchange not abundant, expend excessive fuel, relatively costly etc.
Shortcoming.It is thus desirable to by transforming to existing heat exchanger, improve heat exchanger effectiveness, to meet the needs of production.
Content of the invention
The present invention is directed to the deficiencies in the prior art, provides a kind of higher heat exchange being provided with mixing bunker of heat exchanger effectiveness
Device, reducing energy consumption, improve production efficiency.
The technical scheme is that and be achieved in that: a kind of heat-exchange device being provided with mixing bunker include vapour inlet,
Condensed water and waste gas outlet and heat exchanger, described heat exchanger includes hot water and steam pipe and many be connected with hot water and steam pipe
Radiating tube, has radiating tube fin outside this radiating tube, described heat exchanger one end is provided with heat exchanger air inlet, and the other end is provided with
Heat exchanger gas outlet it is characterised in that: described heat exchanger is multiple levels heat exchanger in parallel；The plurality of heat exchange
The pipeline narrowing for a section is closed up in the heat exchanger gas outlet of device after being interconnected；Set respectively between described adjacent heat radiation pipe
There is mixing bunker, described mixing bunker can make the air of different temperatures after radiating tube in its internal even conjunction of convection current up and down.
Preferably, the quantity of described heat exchanger at least two.
Preferably, the quantity of described radiating tube at least 8.
Preferably, described radiating tube and radiating tube fin are made up of aluminium or copper product.
The present invention solves defect present in background technology, has the advantages that
The heat-exchange device being provided with mixing bunker that the present invention provides, is formed by arranging multiple levels heat exchanger in parallel
One complete heat-exchange device, increased air flow area, in the case of identical amount, reduces the flowing speed of air
Degree, extends the time of contact of air and radiating tube, improves heat exchanger effectiveness, reduce energy consumption.Between two-stage radiation pipe
Add a mixing bunker, make the even conjunction of cross-ventilation of upper and lower different temperatures in mixing bunker, so that heat is sufficiently swapped, heat is handed over
Change rate lifting, improve production efficiency.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
A kind of heat-exchange device being provided with mixing bunker as shown in Figures 2 and 3, including vapour inlet 6, condensed water and waste gas
Outlet 7 and heat exchanger, heat exchanger includes hot water and steam pipe 1 and many radiating tubes 8 being connected with hot water and steam pipe 1, and this dissipates
There is radiating tube fin 2, heat exchanger one end is provided with heat exchanger air inlet 4, and the other end is provided with heat exchanger and gives vent to anger outside heat pipe 8
Mouth 5, heat exchanger is two levels heat exchanger in parallel；After the heat exchanger gas outlet 5 of two heat exchangers is interconnected
Close up the pipeline for a truncated tapered, be so conducive to the quick discharge of hot-air.Set respectively between adjacent heat radiation pipe 8
There is mixing bunker 3, mixing bunker 3 can make by the air of different temperatures after radiating tube 8 in its internal even conjunction of convection current up and down.Radiating tube 8
Quantity at least 8.Radiating tube 8 and radiating tube fin 2 are made up of aluminium or copper product.
The course of work of the present invention is: produces pressure steam with pressure boiler, by pipeline, steam is passed through pressure
Radiating tube 8 and air that hot water and steam pipe 1 is transported in heat exchanger carry out thermal energy exchange, and produce hot-air from heat exchanger
The pipe outlet of gas outlet 5 is discharged, for the drying in producing, heating.This is provided with the heat-exchange device of mixing bunker and is provided with two
Individual level the heat exchanger connecting, are interconnected two heat converter air-out mouths 5, finally will be converged by the hot blast of heat exchanger
Integrated one, so constitute the heat exchanger of two hot switching paths, be equivalent to increase heat exchanger hollow air-flow
Dynamic section.In the case of equal flow, reduce flow velocity, make the time lengthening of air and heat sink contact, heat exchange is more
Plus fully.Air themperature for making air duct upper, middle and lower layer equalizes, and is respectively equipped with mixing bunker in two adjacent groups radiating tube 8
3, make thermal current carry out heat exchange inside it, so that the gas flow temperature of levels is equalized, improve rate of heat exchange.Finally will radiate
The condensed water that pipe produces and waste gas are sent boiler back to by condensed water and waste gas outlet 7 after bottom is collected and are carried out energy recovery profit
With.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
