Description
Technical field
The application is related to dryer field, and in particular to a kind of dryer with heat recovery, is mainly used in cloth
Drying.
Background technology
Drying refers to that high temperature drying cylinder by rotating, by the moisture removal in fabric, makes fabric obtain dry process.Work
When, the drying cylinder inner utilization steam or electric power of rolling cause drying cylinder surface high-temp, cloth be close in drying cylinder outer surface it is passing, this
Can causes cloth flash baking.During drying cylinder runs at high speed, the temperature of drying cylinder determines the quality of drying, in order to carry
High drying temperature, the temperature of drying cylinder is generally all very high, and generally these heats can dissipate in atmosphere, cannot be effective
Utilize, so as to cause the waste of resource.Drying cylinder carries out drying to wet cloth, and substantial amounts of steam can be produced in drying process, these
Steam can be more poly- more, have little time the steam of evaporation and will condense to form the globule on drying cylinder surface, these globules are cumulative, reach
It will be dropped on cloth cover, cloth cover can be polluted to constant weight, so as to cause fabric defect.
Conventional, when not transforming dryer, the heat in drying cylinder is expelled directly out, and this not only results in the wave of heat
Take, but also the hot-air on drying cylinder surface can be caused to condense into the globule, drop in the cloth cover of drying, cause fabric defect, influence
Product quality.
In view of the above-mentioned problems, some producers are correspondingly improved to dryer, such as Fig. 1 of the drying machine structure after improvement
Shown, it includes：

Drawn from the drying cylinder, the drying cylinder condensate for condensate caused by the drying cylinder surface is outwards drawn
Drainage tube 3, and
With the wind-supplying mouth 4 of the intracavity inter-connection of the baking oven.
Its key improvements is that there is provided the drying cylinder condensate drainage tube 3 drawn from drying cylinder 2.During work, drying cylinder surface
Caused condensate is outwards drawn by the drying cylinder condensate drainage tube 3, is discharged outside drying cylinder, so as to avoid the solidifying of drying cylinder surface
Bear water and drop on cloth and influence the quality of cloth product.
However, the condensate drawn from drying cylinder condensate drainage tube 3 is the high-temperature water for having a large amount of heat energy, drying cylinder condensate
Drainage tube 3 has also been taken away the heat of condensed water in high temperature and has been expelled directly out, condensate while condensate is outwards drawn
Heat be not utilized effectively.
The content of the invention

Drawn from the drying cylinder, the drying cylinder condensate for condensate caused by the drying cylinder surface is outwards drawn
Drainage tube 3, and
With the wind-supplying mouth 4 of the intracavity inter-connection of the baking oven.
The key improvements of the present embodiment are：Air-water heat exchanger 5 (i.e. a gas and water are provided with the wind-supplying mouth 4
Heat exchanger, widely say, be the heat exchanger of gaseous material and liquid), above-mentioned drying cylinder condensate drainage tube 3 goes out
Water end (W.E.) is connected with the water inlet end of the air-water heat exchanger 5.
During work, condensed water in high temperature caused by the surface of drying cylinder 2 is led to air-water heat exchanger 5 by drying cylinder condensate drainage tube 3
In, the natural wind filled into from wind-supplying mouth 4 first blows to air-water heat exchanger 5, then flows to above-mentioned each drying cylinder 2, when natural wind passes through
After air-water heat exchanger 5, absorb the heat of condensed water in high temperature in air-water heat exchanger 5 and be warming up to 55 DEG C -65 DEG C, turn into " high temperature
Wind ", high temperature it is distinguished and admirable to inside baking oven 1 so as to the temperature of drying cylinder and oven interior is greatly improved so that heat obtains
Recycling, accelerates the drying rate of cloth A in baking oven 1, but also can reduce the condensation of the surface vapor of drying cylinder 2, reaches
To the purpose for reducing energy consumption, improving drying effect and drying quality.
In order to improve benefit wind velocity, the present embodiment is also provided with (not drawing in figure with the hair-dryer that the gas phase of wind-supplying mouth 4 connects
Go out), to be blown into substantial amounts of wind into baking oven 1 through wind-supplying mouth 4 by the hair-dryer.Obviously, wind-supplying mouth 4 has inlet side and air-out
Side, in the present embodiment, foregoing hair-dryer is arranged on the inlet side of wind-supplying mouth, and foregoing air-water heat exchanger 5 is arranged on wind-supplying mouth
Air side.Natural wind firstly flows through wind-supplying mouth, then it is heated by the air-water heat exchanger 5.
Certainly, air-water heat exchanger 5 directly can also be arranged in wind-supplying mouth 4 by we, and cause natural wind flowing into benefit
While air port 4, the heat of condensed water in high temperature in air-water heat exchanger 5 is absorbed；Or air-water heat exchanger 5 is arranged on benefit wind
The inlet side of mouth 4, when natural wind does not also flow into wind-supplying mouth 4, heat temperature raising just is carried out to natural wind.
Three kinds of arrangements of above-mentioned air-water heat exchanger 5, are included in that described herein " air-water heat exchanger 5 is arranged in
At wind-supplying mouth 4 " in the range of.
