Description
Technical field
The utility model relates to hot air heating system technical field more particularly to a kind of pressure spray drying tower Hot-blast Heatings
System.
Background technique
Currently, the bulky of spray dryer, the thermal efficiency are lower, the design of drying tower is relied solely on, for cocurrent work
Skill effect in terms of energy conservation is extremely limited.Developing two stages drying both at home and abroad, is completing constant speed using drying tower and dry, work as liquid
Body enters back into next stage drier after basically forming solid, improves heat utilization rate.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of press atomizations suitable for solving the above problems to do
Dry tower hot air heating system.
In order to solve the above technical problems, technical solution adopted in the utility model is:
A kind of pressure spray drying tower hot air heating system, it is characterised in that including be placed in the hot wind of dry column overhead into
Mouthful, it is hot wind wind distributing hole plate below the hot wind inlet, whirlwind orifice plate, the drying tower is arranged below in the hot wind wind distributing hole plate
A micro-positive pressure low temperature wind air outlet is set at the bottom plate of bottom and the space of inclined rewinding turntable；Insulating layer is equipped with around drying tower,
And main air hose is equipped with inside insulating layer；The drying tower lower part is equipped with the return air inlet of annular and is pooled to main air hose, heat exchanger channels
It is connected with return air inlet, the other end is equipped with return air channel.
Further technical solution is: the return air channel is connect by variable diameter air duct with main air duct, to balanced wind speed.
Further technical solution is: wind-wind heat exchanger of vertical comb, outdoor fresh air are equipped in the main air hose
It is sent into vertical comb by filter, and hot wind after heat exchange is sent into burner by air blower.
Further technical solution is: before the vertical comb welding, being first set with the inclination installation that one studs with rubber
Porous plate, every comb correspondence penetrate a hole；Porous plate is pulled by two chains, to move up and down.
The beneficial effects of adopting the technical scheme are that
The device is not only energy saving, can also cause the device to produce steadily in the long term, improves the dry thermal efficiency, improves production efficiency,
Guarantee product quality, it is easy to operate, substantially reduce cost；Purposes is wide, is particularly suitable for the drying of feather albumen powder.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
Wherein: 1- hot wind inlet, 2- tower body and insulating layer, 3- hot wind wind distributing hole plate, 4- drying tower, 5- whirlwind orifice plate, 6-
Return air channel, 7- heat exchanger, 8- air blower, 9- return air inlet, 10- heat exchanger channels.
Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that and described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Many details are explained in the following description in order to fully understand the utility model, but this is practical new
Type can also be implemented using other than the one described here other way, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case where novel intension, therefore the utility model is not limited by the specific embodiments disclosed below.
As shown in Figure 1, a kind of pressure spray drying tower hot air heating system, it is characterised in that including being placed in dry column overhead
Hot wind inlet 1, the hot wind inlet 1 is below hot wind wind distributing hole plate 3, and whirlwind hole is arranged below in the hot wind wind distributing hole plate 3
A micro-positive pressure low temperature wind air outlet is set at plate 5, the bottom plate of the dry tower bottom and the space of inclined rewinding turntable；Drying tower week
It encloses and is equipped with insulating layer, and be equipped with main air hose inside insulating layer；The drying tower lower part is equipped with the return air inlet 9 of annular and is pooled to master
Air hose, heat exchanger channels 10 are connected with return air inlet 9, and the other end is equipped with return air channel 6.
Further preferred is: the return air channel 6 is connect by variable diameter air duct with main air duct, to balanced wind speed.
Further preferred is: wind-wind heat exchanger 7 of vertical comb is equipped in the main air hose, outdoor fresh air is logical
It crosses filter and is sent into vertical comb, and hot wind after heat exchange is sent into combustion by air blower 8.
Further preferred is: before the vertical comb welding, being first set with the more of the inclination installation that one studs with rubber
Orifice plate, every comb correspondence penetrate a hole；Porous plate is pulled by two chains, to move up and down.
Equipment enters after drying tower in use, by the input hot wind of hot wind inlet 1 through being passed downwards by hot wind wind distributing hole plate 3
It broadcasts, row to drying tower tower wall opening position, the gas bypass with purge chamber side forms the air curtain of micro-positive pressure；And under its siding
If the drying tower siding of side is equipped with arterial highway annular air channel slot, adherent air curtain layer is formed, the slurry mist cloud of pressure injection is reduced
It is adherent；In the lower section of annular air channel siding, keeps the temperature tower wall internal diameter and expand as an annular passage, inside is additionally provided with opens obliquely upward
The whirlwind orifice plate 5 in hole, causes the vortical flow layer slowly rotated, synthesizes the whirlpool slowly rotated with leading hot wind, changes
The motion profile of the dry droplet of vertical drop, is allowed to rotate along helix, into falling-rate periods of drying state, when extending droplet drying
Between, improve surface drying effect；Achieve the effect that a Hot-blast Heating.
