Based on the original single segmental baffle heat exchanger
    Based on the original single segmental baffle heat exchanger, double/triple segmental baffle floating head heat exchangers are such that the original baffle plate is revised into double notch form, the cut area is increased counter-current flowing state from the counter-current flowing state of the single segmental baffle; overcoming the pipe bundle vibration caused by the drastic flowing of the fluid, the resistance of the shell side pipe bundle is lowered to 1/6-1/8 of that of the single segmental baffle at the same flow rate on the contrary, the flow rate can be improved by more than 2 times under the same pressure drop, thus improving the heat conducting speed.
    The shell pass of double/tri segmental baffle floating head heat exchangers does have the advantages of low pressure drop and large amount of process load. Compared with single segmental baffle heat exchanger, it can save 20%-30%heat exchange area under the condition of obtaining the same heat quantity. Based on the same pressure drop, he general heat conducting rate can be improved by 50% ,and it is new-type energy-saving equipment in the petroleum and chemical industry.
This heat exchange equipment is suitable for the heat exchange of phase transition free fluid in the production of petroleum and chemical industry, especially suitable for the condition of great amount of fluid at shell side and big viscosity.
