Spiral plate heat exchanger optimization design performance what?
Jan 19, 2018

As far as we know, there are two types of spiral plate heat exchangers that can be disassembled and can not be disassembled. The way to distinguish these two heat exchangers is very simple, just observe the structure. Non-removable spiral plate heat exchanger structure is relatively simple, both ends of the spiral channel is welded to death.


In contrast, removable spiral plate heat exchanger in addition to the spiral structure at both ends of the seal, the other with the same non-removable. For mechanical cleaning purposes, one end of the detachable spiral channel is open using a flat plate cover and a gasket seal to prevent fluid from leaking into the atmosphere or shorting fluid within the same channel.


In order to improve the helical plate heat exchanger spiral plate bearing capacity, the distance between the plate with the plate support; and spiral plate heat exchanger tube body fluid inlet and outlet and the tangential take over two , The commonly used is the tangential takeover, because of its fluid resistance, impurities easily washed out.


In addition, the rotary plate can be configured for the spiral plate heat exchanger, this is more convenient, you can stand up or put the heat exchanger lying. Exhaust heat A, B fluid flow through the spiral plate on both sides, respectively, one of the fluid along the spiral passage from the outside to the center outlet; and the other along the helical channel from the center of imports, from the inside out . Both fluids flow in a purely countercurrent manner.


With the existing technology, the maximum structural dimension of the spiral plate heat exchanger is 1,800 mm in width, 1700 mm in outer diameter and 250 mm in heat transfer area, and the distance between the plates is 20 mm; while its maximum allowable operating pressure Up to 2.5 MPa; Operating temperature is dependent on the material selected, most of the material is carbon steel, stainless steel, aluminum, copper and titanium.
