Free-flow plate heat exchanger has obvious advantages, especially when it is used in liquid with solid particles, fibers or high viscous products, such as paper industry, sewage treatment plant, sugar industry, fruit juice production and ethanol production with grain as raw material, heat recovery system and many other special conditions, while ordinary plate heat exchanger is often blocked.
The plate of free-flow plate heat exchanger: The models of heat transfer plates are designed to be 11 mm apart. The sheet is pressed into transverse ripple to keep the flow without "plate-to-plate contact", to keep the flow passage free and barrier-free, and to allow the free flow of media/particles.
There is no metal contact point at the entrance angle of the sheet channel. This will ensure that there is no place to "hang" or pile up fibers, etc. In addition, the design of diversion zone can optimize turbulence and improve heat transfer efficiency. Therefore, the free-flow plate heat exchanger is a good way to solve the problem of insufficient heat transfer of lower heat transfer plate.
