Description

TECHNICAL FIELD

In the process of cold and hot medium flow, the spiral pipeline design will make the temperature of the two media tend to the average value in the transmission process, and the heat exchange efficiency of the existing spiral plate heat exchanger needs to be improved.

[0012] The application provides an energy-saving spiral plate heat exchanger. 1. One of the two groups of conical spiral bodies can be removed from the inside of the group of spiral plates, and a conical cap without a fluid tank is installed, so that the outer fluid area disappears. After the high-temperature fluid is input from the group of conical spiral bodies with an outer fluid area, the low-temperature waste water in the outer fluid area can enter the spiral cavity to assist the heat exchange of the two groups of media with a small temperature difference between the spiral plates. At the same time, the low-temperature medium is pre-cooled by the low-temperature medium, and the pre-cooled low-temperature medium enters the inside of the double-channel conical spiral body, and the low-temperature medium enters the double-channel conical spiral body and exchanges heat with the low-temperature medium.

Since v=Q / A, the average flow velocity (v) in the pipeline is increased under the condition that the pipe diameter A is unchanged, the flow resistance of the heat exchange medium is reduced under the condition that the relative situation is reduced, and the formation of scale in the spiral plate heat exchanger is fundamentally slowed down by reducing the local resistance.

[0014] 3. The drainage pipe connected between the conical spiral bodies is internally provided with a check valve and a pressure pump connected through a flange.
