Spiral plate heat exchanger, zhang ping done by two metal plate made two spiral roll channel, heat and cold, fluid through spiraling wooden partition between in the heat exchanger. Spiral plate heat exchanger is detachable and not detachable two types.
Spiral plate heat exchanger wide application. In China, the ammonia plant of small and medium-sized transform heat exchanger and synthesis tower of the heat exchanger already has used spiral plate heat exchanger replace tubular heat exchanger.
Caustic soda factory of electrolyte heater and strong alkali liquor cooler, adopting spiral plate heat exchanger used equipment fee is only a third of the tubular heat exchanger.
In addition, the heat exchanger used for top condensation, quenching oil cooling, cooling and fatty acid fuming sulfuric acid and good cooling effect. The equipment is used for steam condensation and no phase change of the convection heat transfer effect best, can also be used to boiling heat transfer.
