In this heat recovery energy-saving baking box structure, including furnace body number can be one or more, this hair
The bright particular number for furnace body is not specifically limited；When being provided with multiple furnace bodies, multiple furnace bodies are sequentially connected；Fig. 1, Fig. 2
The present embodiment be a furnace body representative side section view, for hot blast feeding system 15 and dehumidifier blower 5 positional relationship not
Stringent limitation can be configured the layout of hot blast feeding pipeline 15 and dehumidifier blower 5 using existing layout type.
Have several drying cavities 1 in furnace body, be loaded with the trolley of provided with wheels in charka 12(Fig. 1 of glass fibre) it can be
Unidirectional operation in drying cavity 1, to complete the drying to glass fibre.Charka 12 is opened from right to left in Fig. 1, before the right side is, Zuo Wei
Afterwards.
Wherein, each drying cavity 1 has individual heating plant to carry out heat supply, while each drying cavity 1 is interconnected.It changes
Yan Zhi is parallelly distribute between drying cavity 1 and interconnects that centre does not separate, and is contacted with each other between charka 12,
To constitute the drying channel for going out charka 12 into charka 12 to other end from one, the drying channel i.e. hot wind are supplied
Answer pipeline 11.
The dehumidifier air piping 4 of the drying cavity 1 in the several areas in energy-saving baking box foremost is interconnected and concentrates on a reuse
In pipeline 3, the slow situation of efficiency is transported in order to avoid hot wind enters at the top of furnace body after reuse pipeline 3, so that the heat in hot wind
In a large amount of conduction to outside air of amount, dehumidifier blower 5 is installed in reuse pipeline 3, accelerates hot wind being sent into the last of baking oven
Reuse is carried out in one drying cavity 1, is circulated because accelerating hot wind using dehumidifier blower 5 in 2 outside surrounding of charka, is promoted
Drying effect, while reuse decreases the loss that thermal energy is directly brought into behind the external world by dehumidifier wind.
In order to which heat is preferably carried out reuse, one is distributed in the top dehumidifier air piping 4 of each drying cavity 1
A heat exchanger 2, heat is also pulled away while moisture is discharged to the external world by dehumidifier air piping 4, will by heat exchanger 2
Heat in moisture exchanges.And baking oven fills into air and needs through heat exchanger 2, just the heat in moisture is handed at this moment
It changes to and fills into air.The heat increased in drying cavity 1 after air uses in drying cavity 1 is filled into, to reach drying effect
It is promoted.
Further, in order to guarantee the stability of the temperature and humidity in furnace body, guarantee baked products quality and energy
The stability of consumption, further increases energy utilization rate, is arranged on 4 linkage section 41 of dehumidifier air piping that each drying cavity 1 comes out
One conversion valve 13, conversion valve 13 are connected to reuse pipeline 3, dehumidifier air piping 4, and conversion valve 13 and server 7 connect
It connects, Temperature and Humidity device 6 is distributed in the dehumidifier air piping 4 of each drying cavity 1 and shows on the server 7, in server 7
Middle setting limits up and down, once temperature and humidity is more than the range of technological standards, middle control signal feedback to heat recovery section
On the automatic adjustment valve 9 of energy baking oven, controlling opening of valve reduces temperature and humidity wave so that internal temperature and humid control are stablized
The rising of energy consumption after dynamic.When the temperature-humidity signal that the Temperature and Humidity device 6 of any dehumidifier air piping 4 detects meets reuse
When standard, 4 linkage section 41 of dehumidifier air piping is directly connected to reuse pipeline 3 by conversion valve 13, and otherwise dehumidifier air piping 4 connects
Section 41 is connected to dehumidifier air piping 4.
Certainly, increase or reduce quantity and the position of Temperature and Humidity device 6 according to the length of furnace body or drying cavity 1
It sets, the technological standards of temperature and humidity can also be required to be formulated and improved according to the control of production product, but be to ensure that
Temperature and humidity in drying cavity 1 is in a certain range.
Specifically, Fig. 1, Fig. 2 shows a kind of structural schematic diagrams of heat recovery energy-saving baking box of the invention.This field
Ordinary artisan is appreciated that can be set two or more furnaces being sequentially connected in heat recovery energy-saving baking box
Body is not specifically limited the particular number of furnace body.There are six the drying cavities being sequentially connected for the present embodiment setting in the figure
1。
Unlike the prior art, dehumidifier air piping 4 is provided with heat exchanger in heat recovery energy-saving baking box of the present invention
2, it can be seen in the drawing that the heat exchanger 2 is set to 4 top exit of dehumidifier air piping, and it is connect with total dehumidifier air piping.This
The hot wind extracted out in the heat recovery energy-saving baking box of invention is back to use in the last one drying cavity 1, can be in Fig. 1
Find out, the hot wind of two drying cavities 1 in foremost is by direct reuse.Temperature and humidity in heat recovery energy-saving baking box of the invention
Control is to be carried out automatically controlling by server 7 and adjusted the aperture of automatic adjustment valve 9, it can be seen in FIG. 1 that by warm and humid
Spend each cavity of 6 test oven of detector temperature and humidity and in being collected into server 7, for data analyze once occur
Parameter is more than that critical field is arranged in technique, i.e., can feed back to the adjusting that automatic adjustment valve 9 carries out aperture, adjust to temperature and humidity
Section, reduces unnecessary thermo-field thoery, to reduce the consumption of the energy.
Concrete operation step, when baking oven is opened, dehumidifier blower 5 can be automatically turned on, and the hot wind of oven interior also can be with Fig. 1
Route shown in ~ 3 is recycled, and fresh air can enter oven interior from air scoop 14 is filled into and be mixed with internal hot wind, is followed
The hot wind of ring can heat the yarn on charka, so that the moisture of yarn starts to evaporate.The moisture being evaporated can be taken out
The exhaust outlet (at automatic adjustment valve 9) of wet blower 5 is extracted out, and the heat of part is mixed in dehumidifier wind.It is carried out by heat exchanger 2
Heat exchange is transferred heat to fresh air and to fill into air themperature rising, reduced baking oven itself and added using steam to fresh air
The origin temp of heat, the consumption of the energy is reduced with this.
