Abstract
A continuous dryer heat exchanger device has a plurality of heat exchanger units. Waste air of an associated dryer section of the associated continuous dryer is guided through an individual heat exchanger unit and contaminants from the waste air are deposited in the heat exchanger unit. A cleaning device for cleaning the continuous flow heat exchanger device of the contaminants is thereby provided, which cleaning device has a plurality of cleaning units. An associated heat exchanger unit is to be cleaned by means of the individual cleaning unit. A switching device is provided, by means of which the cleaning units are to be switched in series one after the other.
Claims14
A continuous dryer heat exchanger device (30), comprising:
- a plurality of parallel heat exchanger units (32) configured to receive waste air (20) from at least one dryer section (16) of a continuous dryer (10),
- wherein the waste air (20) is separately guided through each of the parallel heat exchanger units (32), and
- wherein contaminants from the waste air (20) are deposited in each heat exchanger unit (32);
- a cleaning device (50) for cleaning the continuous dryer heat exchanger device (30) of the contaminants,
- wherein the cleaning device (50) has a plurality of cleaning units (52),
- each associated with a respective heat exchanger unit (32);
- and
- a switching device (82) configured to switch the plurality of cleaning units (52) in series one after another,
- whereby one of the parallel heat exchanger units (32) can be cleaned at a time while the remaining parallel heat exchanger units (32) remain in operation.
