Heat exchange device and through type drying equipment

Abstract

The invention discloses a heat exchange device and discloses through type drying equipment with the heat exchange device. The heat exchange device comprises a main box body and heat exchange assemblies, a ventilation channel is arranged in the main box body, the ventilation channel is provided with a hot air inlet end and a cold air inlet end, each heat exchange assembly comprises a heat exchange pipe and a plurality of fins, each heat exchange pipe is in a snakelike loop shape, each heat exchange pipe is provided with a water inlet end and a water outlet end, the fins are fixed to the heat exchange pipes, the fins are arranged at intervals, the number of the heat exchange assemblies is two, and the two heat exchange assemblies are arranged on one side, opposite to the hot air inlet end, of the main box body and one side, opposite to the cold air inlet end, of the main box body respectively. The hot air inlet end is connected to redundant heat discharged by a drying unit, and heating is carried out on cold water through the redundant heat. heating is carried out on low-temperature air injected from the cold air inlet end through high-temperature steam exhausted by the drying unit, so that redundant exhausted heat in the whole drying equipment is recycled, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a heat exchange device and a through-type drying equipment. Background technique [0002] Dryers can be divided into industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are one of washing machines. They are generally used to remove clothing and other textiles after washing and dehydration. of moisture. The dryer has several modes such as belt drying, tumble drying, box drying, and tower drying; the through-type dryer is a kind of washing machine, which is generally used to remove clothes after washing and dehydration. and other moisture in textiles. Most dryers consist of a rotating drum with an inner drum driven by a belt, around which hot air is used to evaporate moisture. The drying drum adopts the principle of forward and reverse rotation of the drum to achieve the non-winding effect of drying items. [0003] Am...

AI Technical Summary

Problems solved by technology

[0003] Among them, for the sake of efficiency, a large amount of steam is used for drying, which increases the amount of steam used, and the excess heat in the through-type dryer can only be discharged directly, and the heat cannot be effectively used, resulting in a large amount of energy waste.
