Abstract
Apparatus for cleaning the heat exchanging surfaces of the heat transfer plates of rotary regenerative heat exchangers by using a row of high pressure directional jets of cleaning fluid directed into the interspaces between the plates and hitting deposits positioned in the interspaces essentially in the shape of a moving row of impact points.
Claims13
Apparatus for cleaning the heat exchanging surfaces of the heat transfer plates of a rotary regenerative heat exchanger comprising:
- a plurality of cleaning fluid nozzles (20) directed towards the heat transfer plates, said nozzles (20) being positioned adjacent each other on at least one line and essentially in parallel to the planes of the heat transfer plates;
- means for displacing said nozzles (20) relative to the planes of said plates;
- said nozzles (20) each being dimensioned to produce a directional output jet of high kinetic energy and with a sectional area that at least perpendicular to the planes of said heat transfer plates essentially does not increase in size;
- and
- a cleaning liquid source coupled to said nozzles (20) for supplying said cleaning fluid nozzles (20) sequentially in groups of at least one nozzle with a high pressure cleaning liquid.
