Description

Waste heat recovery device for laundry treatment system {Waste Heating Recycle Device for Washing and Drying System}

The present invention relates to a waste heat recovery apparatus in a laundry treatment system capable of re-introducing and reusing hot air excluding moisture from high-temperature / humidity air generated in the process of processing laundry.

In general, in order to process a large amount of wet laundry in a large laundry shop, the laundry is dried while passing the laundry into a chamber where hot heat is supplied, and then the laundry is transferred to the next process.

At this time, the hot heat used in the drying process is discharged to the outside through the exhaust port connected to the chamber in a state contaminated with the gas generated during the drying of the laundry, and again the fresh air is continuously introduced into the dryer In the process of drying, a considerable amount of heat is released as it is with hot exhaust gas.

Thus, not only does it result in waste of renewable fuels, but also causes environmental pollution.

For example, in the publications of Korean Patent Publication Nos. 2009-0085425, 2010-0135149, 2015-0025071, etc. in connection with a laundry drying facility, waste heat generated during drying of laundry can be recovered and reused. The device is described.

However, in the case of applying an organic solvent recovery system, a complex refrigeration cycle composed of a compressor, a condenser, an expansion valve, and an evaporator is used. Therefore, the facility itself is complicated and the failure rate is high. When used as a necessary heat source, there is a problem that the utilization is greatly reduced.

In addition, Korean Patent No. 0653197 discloses high thermal efficiency by supplying cold air into a housing equipped with a heat exchanger to preheat and circulate primary and secondary to absorb heat retained by the exhaust gas and preheat it to a high temperature. Disclosed is a waste heat recovery apparatus.

However, such a device takes a long time because after the heat exchange is performed as waste heat is discharged, the dryer itself is stopped to deal with sludge generated by waste heat and contaminated gas, and then the operator has to rely on manual cleaning. It involves the problem of wasting unnecessary manpower.
