The condensed water from air - conditioning equipment installed in buildings along the streets including public passageways in neighborhoods , lanes and alleys shall not be discharged onto the outside walls of the buildings or the ground outside 沿道路两侧（包括街坊、里弄内的公共通道两侧）建筑物安装空调设备的，禁止将空调设备的冷凝水排放到建筑物的外墙面和室外地面上。
Based on the analysis of the forms and facilities of the scwr system , the status of scwr was investigated in the industry of printing and dyeing . two projects of scwr system were brought forward and the thermal economics of the scwr system was studied 首先对印染企业的冷凝水回收进行调查研究，提出了两种蒸汽冷凝水回收方案，对两种回收系统进行了管路水力和热力计算，确定了系统各点的热力学参数。
As ammonia built up in the water gas purification system reacts with a part of condensate on the inner wall of the heat exchanger tube passes , and the salt solution formed cools down and crystallizes in the tube passes , the resistance in the shift conversion section increases exceedingly 摘要由于水煤气净化系统积累的氨与部分冷凝水在换热器管程内壁反应形成的盐溶液在管程内冷却结晶，造成变换工序阻力异常增大。
In the event that a boiler does shut down the stop - check must prevent backflow into the boiler , the weight of the disc and dash pot piston , through the force of gravity , promote rapid sealing so steam and condensate cannot backflow into the boiler even at low pressures 如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。
In this paper , at first , the benefits of energy conservation , the fixed number of invested - reclaimed year and the rate of reclaiming were calculated with the conventional method - the tech - economy means for the two scwr projects which were heat pump model scwr system and jet pump model scwr system 用传统的技术经济分析方法，对热泵式蒸汽冷凝水回收系统、喷射泵式蒸汽冷凝水回收系统进行了技术经济比较，得到喷射泵式蒸汽冷凝水回收系统较为适合。
In order to improve the utilization efficiency of energy and equipment , a general steady simulation model of complex cross - feed multi - effect evaporation was established for the purpose of in - depth research on rule of multi - effect evaporation . in this model , the energy - saving measures , including extra steam being led off to preheat material liquid , the condensation water flash and solution flash , were adopted , and the solid separation was also considered in the process of evaporation 为了提高多效蒸发系统能量与设备的利用效率以及深入研究多效蒸发过程的规律,建立了带有冷凝水闪蒸、溶液闪蒸和引出额外蒸汽预热原料液等节能措施并考虑蒸发过程有固相析出的复杂错流多效蒸发稳态模拟通用模型。
Suitable for the domestic water , food processing water , cool the circulating water , the boiler supplies water , exceed the filtration in advance of the pure water , steam condensation water , build well liquid and water flooding in the oil field , chemical liquid medicine , electroplate the filtration that the liquid , much kinds of acid or alkaline solution , emulsifier wash helping , cleaning solution , medical products , ink and water treatment of the semiconductor , electron trade 水过滤器适用于生活用水食品加工用水冷却循环水锅炉供水超纯水的预过滤蒸汽冷凝水油田修井液及注水化学药液电镀液多种酸性或碱性溶液乳化剂洗涤济洗涤液医药制品墨水的过滤及半导体电子行业的水处理。
According to the main cause of the heat loss in the course of conveying and applying steam , the steam - piping system of southwest jiaotong university has been rebuilt by designing and installing pipe rightly , optimizing the heat - insulating material and its thickness , reasonably selecting drainage valve and reasonably reclaiming condensate , the steam exploitation efficiency has been improved 根据蒸汽输送、使用过程中热损失的主要原因，利用管道的正确设计与安装、优化的保温材料和厚度、疏水阀的合理选择及冷凝水的合理回收改造西南交大热力管网，提高了蒸汽的利用效率。
Material balance and energy balance equations of complex multi - effect evaporation system were expressed in matrix equation , which has the advantages of clear structure and high modularization . by holding or omitting correlation block - matrix in matrix equation , matrix equation could be used to describe the difference of forward - feed , back - feed and cross - reed multi - evaporation system with or without solid separation , extra steam being led off to preheat material liquid , condensation water flash , or solution flash . the models include design and operation 该模型利用矩阵方程具有结构清晰和高度模块化的特点,将复杂多效蒸发系统的物料及热量衡算方程组以矩阵形式表达,通过保留或舍弃矩阵中特定功能模块,模型就能代表有或无固相析出、有或无引出额外蒸汽预热原料液、有或无冷凝水闪蒸、有或无溶液闪蒸等不同情况以及各种情况任意组合的并流、逆流、错流多效蒸发过程,从而实现模型的通用性。
