Steam raising for desalination processes; electrolyser; voltage generator/converter

摘要

Saturated steam suitable for sea-water desalination distillation processes is raised by decomposing distilled water from any distillation process 3 in electrolyser 2 into hydrogen and oxygen gases which recombine in burner 4 forming superheated steam which is converted to a greater tonnage of saturated steam by mixing in desuperheater 5 with another part of distilled water from 3. Electrolyser 2 has separate cathodic and anodic half-cells, includes an integral acyclic voltage generator/converter 1, has close to nil ohmic resistance, operates at between 1.229 and 1.47 volts. It comprises conductive plate(s) having cathodic and anodic surfaces on both faces served with falling films of water electrolyte. After passing over these surfaces the electrolyte is cool and regains heat in heat exchanger 6 otherwise wasted in 3, before circulation to surfaces oppositely charged in the other half cell. Generator/converter 1 consists of permanently magnetised steel disc spinning in a slot cut in each anode-cathode plate and is driven by polyphase synchronous electric motor 1a. IMAGE
