Pneumatic Shell And Tube Heat Exchanger U Shaped DN80

Low Price Double Tube Sheet Heat Exchanger And Condenser Machine

Description

The double-tube heat exchanger consists of concentric inner and outer tubes. Hot and cold fluids flow through the gap between the inner tube and the housing, exchanging heat simultaneously. The inner pipe is connected in series with the U-pipe, and both ends of the casing are connected with the straight pipe. The casing heat exchanger has the advantages of simple structure, quick heat transfer area, easy cleaning, convenient disassembly, suitable flow rate and high heat transfer.

design

For the double tube sheet heat exchanger, there are two design concepts: one is that the double tube sheet heat exchanger is used to absolutely prevent the mixing of the medium between the shell and the tube, and it is designed to be installed on the cavity between the inner and outer tube sheets. The drain valve is used for daily observation and discharge when the inner tube sheet leaks, so that the medium on the shell side is effectively isolated by the inner and outer two-layer tube sheets. This is the main reason for adopting the double tube sheet structure type. Another thinks that the double tube sheet heat exchanger can be used in the case where the medium pressure difference between the tube and shell sides is large, and a medium is designed to be added to the cavity between the inner and outer tube sheets to reduce the pressure of the medium between the tube and shell sides. Difference. This is the same as the general single tube sheet heat exchanger, which cannot be absolutely guaranteed to prevent leakage from the orifice of the outer tube sheet. The isolation cavity between the double tube sheets is the main difference from the structure of the single tube sheet heat exchanger (as shown in the figure, the isolation cavity is not connected to the tube side and the shell side, and does not bear the pressure of the medium, but bears the mechanical load and heat of the equipment). Load.

The bearing capacity of the isolation cavity mainly depends on the distance between the double tube sheets. When the fixed double tube sheet is subjected to the shell-side hydrostatic test, there may be leakage at the connection between the inner tube sheet and the heat exchange tube. Therefore, when determining the distance between the double tube sheets The minimum space required for observation and leak detection must be considered
