纯电低温降膜节能蒸发器 Pure Electric Low Temperature Falling Film Energy Saving Evaporator
工作原理 Working principle
热泵低品能回收节能技术作为当今优良和高效的节能技术在欧美国家已被广泛应用于各个行业的蒸发和干燥领域。沙家浜医药化工装备股份有限公司的低温热泵节能蒸发器引进德国低温热泵蒸发技术，并二次技术创新开发了热泵蒸发技术使热泵的能效比 COP 达到了10以上，能为客户提供设备设计、制造、安装调试、运行等成套解决方案及服务，为国内蒸发器的更新换代及节能、环保事业贡献自己的一份力量。热泵蒸发器采用逆卡诺原理其实就是从需要冷却的环境中吸收热量，通过绝热压缩使其升温，将热量传递给高温介质(接受温度的物体),放出热量之后，进行绝热膨胀，使温度降低至初始温度，回到最初的状态，从而完成一个循环。热量通过工质完成交换。在压缩机两端输出热源和冷源同时对物料进行蒸发和对蒸汽进行冷凝。与此同时高真空度保证物料能在较低的温度下进行蒸发。热泵蒸发技术在蒸发应用上最为高效节能及环保。更适合热敏性物料的蒸发。 As an advanced and efficient energy-saving technology,heat pump low-grade energy recovery technology has been widely appled in the evaporation and drying fields of vanious industries in Europe and the United States. Shajiabang Phamaceutical and Chemical Equipment Co,LTD,the low-temperature heat pumpenergy- saving evaporator introduced the Geman low-temperature heat pump evaporation technology,and the secondary technological innovation developed the heat pump evaporation technology to make the heat pump energy efficiency ratio COP reached more than 10,can provide customers with equipment design, manufactuning,installation and commissioning,operation and other complete solutions and services.For the domestic evaporator replacement and energy saing,environmental protection to contribute to their own strength. The inverse Camot prinople of the heat pump evaporator is actualy to absorb heat from the environment that needs to be cooled,heat up through adiabatic compression,transfer heat to the high temperature medium(the objec that accepts the temperature),release heat,adiabatic expansion,reduce the temperature to the initial temperature,retum to the initial state,so as to complete a cycle.Heat is exchanged through the working medium.The output heat source and cold source at both ends of the compressor vaporize the material and condense the steam at the same time.At the same time,the high vacuum ensures that the material can be evaporated at very low temperatures.Heat pump evaporation technology is the most energy-efficient and enironmentaly friendly in evaporation applications.More suitable for evaporation of heat-sensitive materials.

主要特点 Main feature
相较于传统蒸发技术，热泵蒸发技术在能耗上可以节约70%~90%; 其热源为电。开机后无需任何蒸汽供热或者作为辅助热源，因而大大节省设备的配套设施的投资及消耗；由于热泵其自身可以同时输出冷媒对物料产生的蒸汽进行冷凝并回收蒸汽潜热，所以无需任何外部的冷却水供应，因而大大节省设备的配套设施及冷却水和电的消耗； 40~50°℃低温蒸发。真空度达74Kpa。更加适合中药等热敏性物料。由于蒸发温度低设备不易结垢，清洗方便。蒸发温度低对设备的腐蚀程度降到较低，延长设备的寿命；自动化程度高，全自动化控制及运行，所需操作人员少。相比较于MVR 蒸发器，其操作简单，控制点少，自动化程度更高，故障率低，运行稳定，维修及保养成本较低；管式降膜蒸发是将料液自降膜蒸发器加热室上管箱加入，经液体分布器均匀分配到各换热管内，在重力及气流作用下成均匀膜状自上而下流动，流动过程中被壳程加热介质加热汽化，产生的蒸汽与液相共同进入蒸发器的分离室，汽液经充分分离，分别排出二次蒸汽及浓缩液。强制降膜蒸发器，是在普通的降膜蒸发器中加入大流量循环泵，以提高液膜厚度减少结垢，可减少和防止“干壁”现象。降膜蒸发器且可以有效降低泡沫夹带现象的发生。 Compared with traditional evaporation technology,heat pump evaporation technology can save 70%~90%in energy consumption; Its only source of heat is electricity.There is no need for any steam heating or as an auxiliary heat source after start-up,thus greatly saving the investment and consumption of supporting facilities of the equipment; Because the heat pump itself can output the refrigerant at the same time to condense the steam generated by the material and recover the latent heat of the steam,there is no need for any external cooling water supply,thus greatly saving the supporting facilities of the equipment and the consumption of cooling water and electricity; 40~50℃ low temperature evaporation.The vacuum degree is 74KpaIt is more suitable for Chinese medicine.Due to the low evaporation temperature,the equipment is not easy to scale and easy to clean.The low evaporation temperature minimizes the corrosion degree of the equipment and prolongs the life of the equipment; High degree of automation,fully automated control and operation,less operator required. Compared with MVR evaporator,its operation is simple,less control points,higher degree of automation,low failure rate,stable operation, repair and maintenance costs are very low;Tubular falling film evaporation is to add the material liquid from the upper tube box of the falling film evaporator heating chamber,evenly the liquid distributor,and flow into a uniform film from top to bottom under the action of gravityseparation chamber of the evaporator together. The steam and liquid are fully separated,and the secondary steam and concentrated iquid are discharged respectively.The forced faling film pump to the ordinary flling film evaporator to improve the liquid film thickness and reduce scaling,which can reduce and prevent the phenomenon of "dry wall.The falling film evaporator can effectively reduce the occurrence of foam entrainment.
