SUMMERY OF THE UTILITY MODEL
The utility model overcomes above-mentioned technique is not enough, provides a drying device convenient to energy saving and emission reduction.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
The utility model provides a drying device convenient to energy saving and emission reduction, includes oven 1, heating cabinet 2 and heat exchanger 3, be equipped with the heater in the heating cabinet 2, oven 1 air outlet through return air pipe 41 to heating cabinet 2 return air, be connected with on the heating cabinet 2 and be used for the fan 5 that takes out the gas in the heating cabinet 2, fan 5 output passes through air-supply line 42 to oven 1 air inlet, be equipped with new trend inlet port 31 on the heat exchanger 3 and be connected with respectively and be used for following the wind that new trend inlet port 31 got into heat exchanger 3 sends to new trend conveying pipe 32 in the heating cabinet 2, be used for with wind portion in the return air pipe 41 distributes to heat exchanger 3's first exhaust connecting pipe 33 and is used for will getting into the second exhaust connecting pipe 34 of the wind output of heat exchanger 3 through first exhaust connecting pipe 33.
According to the drying device convenient for energy conservation and emission reduction, the fresh air inlet 31 is connected with the fresh air inlet pipe 311.
Compared with the prior art, the beneficial effects of the utility model are that:
According to the scheme, the air outlet of the oven, the air return pipe, the heating box, the fan and the air inlet of the oven are sequentially connected to form a loop, so that the recycling of old air is facilitated, the temperature of the old air is increased as required, the energy conservation and emission reduction are facilitated, and the oven has substantial characteristics and progress; in addition, the first exhaust connecting pipe is used for sending the air part in the return air pipe to the heat exchanger, then discharging the air part through the second exhaust connecting pipe, sending the fresh air entering from the fresh air inlet to the heating box through the heat exchanger and the fresh air conveying pipe, so that part of the old air in the device is discharged to reduce the concentration of harmful gas, and part of the fresh air is supplemented to the device to reduce the concentration of the harmful gas, and in the process, the discharged old air is subjected to heat exchange preheating on the supplemented fresh air through the heat exchanger, so that heat recovery is facilitated, energy-saving control is realized, and the device has substantive characteristics and progress; in addition, the fresh air conveying pipe is connected to the heating box and not directly connected to the drying oven, so that the problem that the drying effect is influenced because wind with insufficient temperature directly enters the drying oven can be avoided.
