Abstract

The present invention discloses a double side liquid film reverse cross double scale ripple plate absorber heat exchanging element, which includes at least two groups double scale ripple plate heat conduction plate bundles (1) disposed vertically that has a double crossing harrow type guide devices (2) mounted between each corresponding pair of plates. The harrow type guide device (2) includes an upper edge (21), the lower surface of the upper edge (21) is disposed with a guide tongue (22), and the side surface of the upper edge (21) is disposed with a liquid blocking piece (23). The present invention can realize the reverse for the double side liquid film, and fully uses the heat conduction surface of the heat exchanging element, improves the absorb ability of the solution liquid film on the heat exchanging element, and has excellent strengthen heat conduction and mass transfer characteristics.

Description

technical field [0001] The invention relates to a heat exchange element of a corrugated plate absorber, in particular to a heat exchange element of a double-sided liquid film reverse crossing double-scale corrugated plate absorber. Background technique [0002] Liquid film heat and mass transfer is a widely used heat and mass transfer technology. However, the existing research results on the falling film absorption process of lithium bromide solution show that along the direction of the liquid film flowing downward, as the absorption process continues, the temperature of the outer layer of the liquid film is higher and the solution mass fraction gradually decreases; In the first layer, the temperature gradually decreases and the mass fraction of the solution changes little, that is, the outer layer cannot be cooled down, and the inner layer cannot be diluted. Liquid film inversion technology is a more effective measure to improve heat and mass transfer. However, the existi...
