The role of spacer column in the spiral plate heat exchanger is introduced. When the spacer column is machined, the one end of the spacer column should be chamfered and the height deviation of the spacer column should be controlled. , Should choose the appropriate arrangement and welding methods; pointed out that the outermost circle of spiral body welding a certain amount of unequal length of the importance of column spacing.
