Description
技术领域technical field
本实用新型涉及降膜蒸发耦合吸收式制冷高盐污水处理设备。The utility model relates to a falling film evaporation coupled absorption refrigeration high-salt sewage treatment equipment.
背景技术Background technique
高盐污水是指总含盐质量分数等于或高于1％的废水，主要来自于化工厂，石油开采及大规模海水淡化等工业过程，高浓度的卤水和化学废水不能直接排入城市废水系统，必须运往特殊的工厂处理，去除高盐废水中有害污染物对环境产生的影响至关重要。工业生产过程中，经常会产生各种废液、污水等，通常利用物理化学、生物处理的方法将废水、废液中的污染物去除。但实际运行过程中，能耗巨大，装置庞大，不利于维护运行，难以推广运行和实现污水的有效处理。High-salt sewage refers to wastewater with a total salt content equal to or higher than 1%, mainly from industrial processes such as chemical plants, oil exploration, and large-scale seawater desalination. High-concentration brine and chemical wastewater cannot be directly discharged into urban wastewater systems , must be transported to a special factory for treatment, and the removal of harmful pollutants in high-salt wastewater is of great importance to the environment. In the process of industrial production, various waste liquids and sewage are often produced, and the pollutants in waste water and waste liquid are usually removed by physical, chemical and biological treatment methods. However, in the actual operation process, the energy consumption is huge and the device is huge, which is not conducive to maintenance and operation, and it is difficult to promote the operation and realize the effective treatment of sewage.
近年来又出现了许多其它的处理技术，例如多效蒸发(MED)、蒸汽压缩冷凝(VC)、多级闪蒸(MSF)等方法。但是在使用过程中同样出现多种问题。多效蒸发装置单机处理能力低、易结垢，高浓度废水易结焦，设备的工程造价高以及传热效率低；蒸汽压缩冷凝这种处理工艺，对设备材质的要求极高，且系统运行过程中需要消耗大量的热量，投入成本高，运行费用高；多级闪蒸技术虽然能够解决多效蒸发中存在的结焦严重的问题，但因其能耗巨大、占地面积大、热重复利用率等问题，难以大量投入使用。In recent years, many other treatment technologies have appeared, such as multiple effect evaporation (MED), vapor compression condensation (VC), multi-stage flash evaporation (MSF) and other methods. However, various problems also occur during use. The multi-effect evaporation device has low single-unit processing capacity, is easy to scale, and high-concentration wastewater is easy to coke. The engineering cost of the equipment is high and the heat transfer efficiency is low. It needs to consume a lot of heat, high input cost, and high operating cost; although multi-stage flash evaporation technology can solve the serious problem of coking in multi-effect evaporation, it has a large energy consumption, large floor area, and high heat reuse rate. And other problems, it is difficult to put into use in large quantities.

Due to the heat on the outside of the wall, the liquid film achieves a good heat transfer effect through the heat conduction of the liquid film and the convection of the gas-liquid two-phase during the flow process, and may be accompanied by liquid evaporation. It is an efficient heat and mass transfer technology. And in the process of use, it can be driven by low-quality energy to realize heat transfer with slight temperature difference.

It is a simple and efficient refrigeration method with simple structure and convenient operation. With thermal energy as the driving energy, in addition to the thermal energy generated by boiler steam and fuel, it can also utilize low-grade thermal energy such as waste heat, waste heat, and solar energy. The dual purposes of cooling and heating (heating) can also be achieved in the same unit. Except for the pump and valves, most of the whole set of equipment is a heat exchanger, which runs quietly and has little vibration; at the same time, the refrigerator operates in a vacuum state, and has a simple structure, safety and reliability, and is easy to install.
