Drying system having a thermal engine

摘要

A system for drying vehicle bodies and/or for controlling the temperature thereof. The system includes a cabin and has a heater for heating hot air for the cabin. The system is equipped with a mechanical energy-consuming device, for example, a generator and/or a fan. The heater contains at least one heat exchanger. The hot exhaust gas of a thermal engine can be supplied to the heat exchanger. The thermal engine is coupled to the mechanical energy-consuming device, for example, the generator, so as to move together. Because of the coupled movement, mechanical energy can be transmitted from the thermal engine to the mechanical energy-consuming device.

1. A drying system comprising:
a temperature-controllable drying cabin for heating-up workpieces and discharging exhaust gas; a heating arrangement for heating-up intake air supplied to said drying cabin; a consumer; a thermal engine generating hot exhaust gas during operation thereof and being movably coupled to said consumer for transmitting mechanical energy from said thermal engine to said consumer; said heating arrangement including a heat exchanger charged with said hot exhaust gas of said thermal engine and being adapted to draw heat from said hot exhaust gas to heat said intake air supplied to said drying cabin; a spray booth for applying spray paint to workpieces; said spray booth having an extraction system including a fan for drawing exhaust gas charged with hydrocarbons from said spray booth; a supply source for supplying combustion gas from outside of said system; a mixing chamber operatively connected to said supply source, said spray booth and said drying cabin for receiving and mixing said combustion gas, said exhaust gas from said spray booth and/or said exhaust gas from said drying cabin; and, said thermal engine being connected to said mixing chamber to generate said hot exhaust gas from said combustion gas, said exhaust gas from said spray booth and/or said exhaust gas from said drying cabin.
