Description
Technical field
The present invention relates to a kind of vertical arrow tail micro-structural liquid film evaporation heat exchanger, be specially a kind of industrial liquid film evaporation heat exchanger.
Background technology
Liquid film evaporation device is as a kind of efficient heat transfer mass transfer technology, have a wide range of applications in a lot of field, such as, the thin liquid film cooling, novel solar collector cooling etc. of film type evaporator, liquid film deduster, high molecular polymer processing, coke oil slurry overheavy firing, large scale integrated circuit.
Heat exchanger surface conventional in industrial heat exchange device mostly is common metal material, and its surface energy is higher and contact angle is less, is easy wetting surface, is difficult to form dropwise condensation, and therefore, most industry heat exchanger is film condensation.But when heat exchanger surface temperature is higher or coolant flow is lower, easily cause liquid film to break, thus reduce heat transfer efficiency.
Summary of the invention
For the shortcoming such as liquid-sheet disintegration, deterioration heat transfer that current industrial heat exchanger exists, the invention provides a kind of vertical arrow tail micro-structural liquid film evaporation heat exchanger, comprise: flat plate heat exchanger 1, it is rectangular enclosure slab construction, described flat plate heat exchanger 1 one side is uniformly distributed vertical arrow tail micro-structural 2, and described flat plate heat exchanger 1 is distributed with that one of vertical arrow tail micro-structural 2 faces up with horizontal direction is that 80 ° of angles are fixed, and top and bottom, described flat plate heat exchanger 1 side are communicated with hot water inlet pipe 3 and hot water outlet pipe 4 respectively; Liquid distributor 5, it is cavity pipe, the horizontally disposed top being distributed with vertical arrow tail micro-structural 2 one side in described flat plate heat exchanger 1, and is evenly arranged multiple liquid distributing hole 6 below described liquid distributor 5.
Described vertical arrow tail micro-structural 2 cross section is rectangular recess, and arrow stern construction angle is 90 °.
Described vertical arrow tail micro-structural 2 is to be transversely interconnected, and in longitudinal direction, the mode of equidistantly distribution is evenly arranged in described flat plate heat exchanger 1 surface.
Preferably, described one vertical arrow tail micro-structural liquid film evaporation heat exchanger, wherein said flat plate heat exchanger (1) material therefor is the metal material that heat conductivility is good.
Preferably, described one vertical arrow tail micro-structural liquid film evaporation heat exchanger, wherein said liquid distributor 5 is cooling water inlet device.
One provided by the invention vertical arrow tail micro-structural liquid film evaporation heat exchanger, by increasing vertical arrow tail micro-structural 2 on flat plate heat exchanger 1 surface, thus restrained effectively liquid film blockage effect, increasing liquid film area coverage, enhance the disturbance of thin film drainage, improve the heat exchange amount of unit are.
