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 of the exchanger). This fluid will be subject to a very low-pressure loss. In fact, gravity will be the sole force used to push this fluid through the exchanger. This fluid can be highly polluted even with mechanical impurities. • A secondary fluid, flowing inside the rotor, counter current to the primary one. This fluid must be free from mechanical impurities, which might remain trapped in the rotor due to the separating effect of the centrifugal force generated during rotation. The patented technology that lies behind the RHeX design is based on the idea that the whole exchanging surface is constantly kept in rotation and its movement induces 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.
