This paper presents a review of the bubble column evaporator (BCE) and its many novel applications. The BCE process offers a continuously produced source of high air–water interface and consequently provides high overall heat and mass transfer coefficients. Although the bubbling process itself is both simple to use and apply, our understanding of the fundamental physical and chemical principles involved is surprisingly limited and there are many issues yet to be explained. Recently the process has been used to develop new methods for the precise determination of enthalpies of vaporisation (ΔHvap) of concentrated salt solutions, as an evaporative cooling system, a sub-boiling thermal desalination unit, for sub-boiling thermal sterilisation, for low temperature thermal decomposition of different solutes in aqueous solution and for the inhibition of particle precipitation in supersaturated solutions. These novel applications can be very useful in many industrial practices, such as desalination, water/waste water treatment, thermolysis of ammonium bicarbonate (NH4HCO3) for the regeneration in forward osmosis and refrigeration related industries. The background theories and models used to explain the BCE process are also reviewed and this fundamental knowledge is applied to the design of BCE systems and to explain recently explored applications, as well as potential improvements. Many other prospective applications of the BCE process are also reported in this paper.

泡罩塔蒸发器及其应用的洞察

本文综述了泡罩塔蒸发器 (BCE) 及其许多新颖的应用。BCE 工艺提供了一个连续生产的高空气-水界面源,因此提供了高的整体传热和传质系数。尽管鼓泡过程本身使用和应用都很简单,但我们对所涉及的基本物理和化学原理的理解却非常有限,还有许多问题有待解释。最近,该过程已被用于开发精确测定浓盐溶液汽化焓 (ΔHvap) 的新方法,作为蒸发冷却系统、亚沸热脱盐装置、亚沸热灭菌、用于水溶液中不同溶质的低温热分解和抑制过饱和溶液中的颗粒沉淀。这些新颖的应用在许多工业实践中非常有用,例如海水淡化、水/废水处理、碳酸氢铵 (NH4HCO3) 的热解,用于正渗透和制冷相关行业的再生。还回顾了用于解释 BCE 过程的背景理论和模型,并将这些基础知识应用于 BCE 系统的设计,并解释最近探索的应用程序以及潜在的改进。本论文还报告了 BCE 过程的许多其他前瞻性应用。如海水淡化、水/废水处理、碳酸氢铵 (NH4HCO3) 的热解,用于正渗透和制冷相关行业的再生。还回顾了用于解释 BCE 过程的背景理论和模型,并将这些基础知识应用于 BCE 系统的设计,并解释最近探索的应用程序以及潜在的改进。本论文还报告了 BCE 过程的许多其他前瞻性应用。如海水淡化、水/废水处理、碳酸氢铵 (NH4HCO3) 的热解,用于正渗透和制冷相关行业的再生。还回顾了用于解释 BCE 过程的背景理论和模型,并将这些基础知识应用于 BCE 系统的设计,并解释最近探索的应用程序以及潜在的改进。本论文还报告了 BCE 过程的许多其他前瞻性应用。还回顾了用于解释 BCE 过程的背景理论和模型,并将这些基础知识应用于 BCE 系统的设计,并解释最近探索的应用程序以及潜在的改进。本论文还报告了 BCE 过程的许多其他前瞻性应用。还回顾了用于解释 BCE 过程的背景理论和模型,并将这些基础知识应用于 BCE 系统的设计,并解释最近探索的应用程序以及潜在的改进。本论文还报告了 BCE 过程的许多其他前瞻性应用。
