In some experimental conditions of M. D. for concentrated aqueous solution, it is impossible to concentrate the solution to saturation because of the interference of vapor pressure falling and dialysis. No M. D. -crystallization phenomenon is observed in this case even if the solute is easy to crystallize. In this work, the M. D. of concentrated NaCl solution was used as an example, the relationship between the balance concentration, in which M. D. and dialysis were in equilibrium, and temperature condition...

In some experimental conditions of M. D. for concentrated aqueous solution, it is impossible to concentrate the solution to saturation because of the interference of vapor pressure falling and dialysis. No M. D. -crystallization phenomenon is observed in this case even if the solute is easy to crystallize. In this work, the M. D. of concentrated NaCl solution was used as an example, the relationship between the balance concentration, in which M. D. and dialysis were in equilibrium, and temperature condition was analysed. It was necessary to choice a temperature difference which was big enough to make the M. D. in dominance during whole process. When the balance concentration was higher than the saturated concentration of solute, the M. D. crystallization phenomenon would be observed. The experimental basis to choice temperature condition was suggested in this paper.

由于蒸气压下降和透析现象的干扰,在某些实验条件下的浓水溶液膜蒸馏不可能把溶液浓缩到过饱和状态,因此观察不到膜蒸馏一结晶现象,既使溶质是易结晶物质。本文以氯化钠的浓水溶液膜蒸馏为例,分析了膜蒸馏过程和透析过程相平衡的浓度与所采用温度条件的关系,表明必须选择足够大的温差条件,以使在整个过程中膜蒸馏占主导地位,其平衡浓度大于溶质的饱和浓度,才能发生膜蒸馏国—结晶现象,文中提出了选择温度条件的实验依据。

Heat transfer and foullng-resistant properties of mechanically fabricated porous surface tubes in the process of evaporization are studied on this condition of constant heat flux with NaCl and CaSO_4·2H_2O solutions as working liquids. The results show that porous surface tubes can prevent deposit of NaCl within porous surface and have excellent heat transfer properties when the concentration of NaCl solution is lower than critical concentration. Within the range of heat flux in the experiment, heat transfer coefficient of porous surface tubes is 2.8 times that of plain tube (with NaCl solution as working liquid) and boiling heat transfer temperature difference of porous surface tubes is only 1/10~1/8 of that of plain tube (with distilled water as working liquid) and 1/2.6 (with NaCl solution as working liquid). For CaSO_4·2H_2O solution, porous surface tubes always have excellent heat transfer properties even if the solution is in saturation state.

在恒热流密度的工况下,分别以NaCl和CaSO_4·2H_2O水溶液为介质,研究了机械加工表面多孔管在蒸发过程中的传热和抗垢性能。当NaCl水溶液的浓度低于某一临界浓度时,多孔管可以防止NaCl在多孔层内析出,具有高效的传热性能。在实验的热负荷范围内,其沸腾给热系数为光管的2.8倍(NaCl溶液),沸腾传热温差仅为光管的1/(10)~1/8(蒸馏水)和1/(2.6)(Nacl溶液)。对CaSO_4·2H_2O水溶液,即使溶液的浓度达到饱和浓度,多孔管也始终能保持其优越的传热性能。
