RHeX Rotating Heat Exchanger for effluent water
The natural evolution of the RCR design: how to turn an acclaimed winner into an even better performer
The RHeX enhanced rotating heat recovery unit is a recent development of the original RCR design; its main purpose as an exchanger is to be able to treat a very polluted stream of effluents minimising the effects of fouling and clogging, which standard heat exchangers are normally subject to. The exchanger is basically made to treat two streams of counter current fluids: • A primary fluid, flowing outside the rotor of the exchanger inside the trough. This fluid will be subject to a very low-pressure loss. In fact, gravity will be the sole force used to push it through the exchanger even in case it is highly polluted with mechanical impurities. • A secondary fluid, flowing inside the rotor, counter current to the primary one, will always be clean and free from mechanical impurities, The patented technology that lies behind the RHeX design is based on the idea that the whole exchanging surface is constantly kept in rotation inducing a centrifugal action that helps keeping the exchanger clean. In addition to its anti–fouling action, the shape of the rotating disks, which are the actual exchanging surface of the machine, allows for a positive pushing action exerted on the primary fluid towards the outlet port of the exchanger, reducing the pressure loss on this circuit. Furthermore, in the new RHeX design each disk composing the rotor is no longer welded to the next one but simply mounted on a central shaft with interposition of a gasket, allowing substitution in case of damage. It is overall a self-standing, robust and compact ancillary unit improving the efficiency of the machine or system to which it is connected.
