Heat exchanger industry related knowledge

2013-9-5 read:2152

Heat exchanger ( English Translation: heat exchanger ), is a hot portion of the fluid transfer heat to the cold fluid equipment, and heat exchanger. The heat exchanger is chemical, petroleum, power, food and many other industrial sectors of the general equipment, in production plays an important role in. Heat exchanger Fluid flows through the tube and shell selection. 1) do not clean and easy to scale the fluid should take tube, pipe cleaning convenient. 2) corrosive fluid should go to tube, tube bundle and shell and corrosion, and the tube is convenient for cleaning and maintenance. 3) high pressure fluid should go to tube, casing pressure, can save the consumption of metal shell. 4) saturated steam should walk hull distance, to remove condensate, and steam cleaner, so as to avoid the pollution of shell. 5) the cooled fluid should walk hull distance, easy heat radiation, enhance the cooling effect. 6) toxic fluid should take tube, to reduce the chances of losing environment. 7) the high viscosity liquid or small flow rate of fluid should walk hull distance. 8) if the two fluid temperature difference larger, a larger fluid should walk hull distance, to reduce tube wall and the shell wall temperature difference. In short, the fluid flow channel selection principle should be based on good heat transfer effect, convenient cleaning and other specific circumstances, specific analysis, seize the main contradiction. Heat exchangers installed base must be met in order to make the heat exchanger does not happen to sink, or make the pipe the excessive deformation to the heat transfer pipe. Base is generally divided into two kinds: one kind is the brick saddle foundation, heat exchanger without saddle and placed directly on the saddle base, heat exchanger and the base is not fixed, with the thermal expansion of the need to move freely. A concrete foundation, through the heat exchanger to saddle support by anchor bolt with its solid foundation to link up.
