一种基于节水预期成本投入的火电厂节水减排数学求解系统 技术领域
本发明涉及发电厂水处理技术领域，具体是一种基于节水预期成本投入的火电厂节水减排数学求解系统。
 背景技术
近年来，我国现代化和工业化进程不断提速，废水排放总量也呈现持续增长态势。我国废水排放总量从2001年的433亿吨增长到2012年的685亿吨，12年间增加了252亿吨，平均每年多排放了21亿吨废水，平均年复合增长率约4.3%。我国废水污染源主要分为工业源、农业源、城镇生活源，以及少量的集中式污染设施排放源。在三种废水污染源中，工业废水特点是排放数量及污染物含量相对小，污染物种类多、治理难度大，引起水环境发生质化污染。
对比文件1（公开号CN112142233A）公开了一种火电厂循环水排污水全膜法零排放处理系统及方法，包括调节水池、双碱法联合软化混凝澄清处理系统、多介质过滤器、超滤处理系统、纳滤处理系统及反渗透处理系统；调节水池的出口与双碱法联合软化-混凝澄清处理系统的入口相连通，双碱法联合软化混凝澄清处理系统的出口与多介质过滤器的入口相连通，多介质过滤器的出口经超滤处理系统与纳滤处理系统相连通，纳滤处理系统的产水出口与反渗透处理系统相连通，纳滤处理系统的浓水出口与外界脱硫系统的工艺水箱相连通，该系统及方法能够实现循环水排污水零排放，满足火电厂节水减排的环保要求，且处理成本低。
对比文件2（公开号CN111363590A）公开了一种火电厂碳减排系统，所示火电厂碳减排系统包括火电厂锅炉、汽机和发电机设备，所述火电厂锅炉与汽机连接，所述汽机与发电机设备连接；所述火电厂碳减排系统还包括热解气化装置、热解气供气管路和多燃烧燃烧器，多燃烧燃烧器设置在火电厂锅炉上，热解气化装置通过热解气供气管路与多燃烧燃烧器连接，所述热解气化装置能够将煤炭、生物质、垃圾、污泥燃料中的任意一种热解为热解气，供给火电厂锅炉进行混配燃烧。
由于我国水资源与煤炭能源的分布特征以及火电厂对二者的需求特点，用水形势日趋紧张，严重地限制了火电厂的发展。火电厂节水模型的研究，对减少单位发电量水耗、提高水资源利用水平有着很重大的现实意义，火电厂节水模型的建立以水平衡测试试验以及用水水质分析为数据依据，目的在于寻求火电厂先进的节水技术、合理的水处理工艺以及完善的水务管理方式。
因此，针对以上现状，迫切需要开发一种基于节水预期成本投入的火电厂节水减排数学求解系统，以克服当前实际应用中的不足。

实施例1
请参阅图1-6，本发明实施例中，一种基于节水预期成本投入的火电厂节水减排数学求解系统，包括相互连接的监测平台100和水处理系统200，监测平台100辅助决策者通过数据、模型和知识，以人机交互方式对水处理系统200进行半结构化或非结构化决策，水处理系统200用于对火力发电厂用水及废水进行零排放处理。
所述水处理系统200包括有沿水处理顺序依次连接的第一水处理单元、第二水处理单元、第三水处理单元和第四水处理单元。
不同类型火力发电厂废水的种类较多，水质、水量的特性差异很大。一般情况有机污染物少，除了油之外，废水中的污染成分主要是无机物；另外，间断性排水较多，连续排水量一般不大。火力发电厂废水一般可以按照以下指标进行分类：
（1）按照废水的来源划分
按照废水的来源划分，火力发电厂的废水包括循环水排污水、灰渣废水、工业冷却水排水、机组杂排水、含煤废水、油库冲洗水、化学水处理工艺废水、生活污水、脱硫废水等。
（2）按照废水的流量特点划分
按照流量特点，废水分为经常性废水和非经常性废水。经常性废水包含火力发电厂在正常运行过程中，各系统排出的工艺废水，这些废水是连续排放的，也有间断性排放的。火力发电厂的大部分废水为间断排放，连续排放的废水较少。连续排放的废水主要有锅炉连续排污、汽水取样系统排水、部分设备的冷却水、反渗透水处理设备的浓排水；间断性排水包括锅炉补给水处理系统的工艺废水、凝结水精处理系统的再生排水、锅炉定时排污、化验室排水、冷却塔排污及各种冲洗废水等。
非经常性废水包含设备检修、维护、保养期间产生的废水，如化学清洗排水（包括锅炉、凝汽器和热力系统其它设备的清洗）、锅炉空气预热器冲洗排水、机组启动时的排水、锅炉烟气侧冲洗排水等。与经常性排水相比，非经常性排水的水质较差而且不稳定。
（3）按照废水的水质特点划分
根据电厂不同系统用水的水质差异，将废水进行回用，可以根据废水的悬浮物和含盐量两个代表性指标进行分类。按照来源划分，废水种类很多，这给废水处理系统的选择带来了很大的困难。从回用角度分析，从处理工艺的相似性来划分。废水分类处理的一个原则是在保证可靠性的前提下，尽可能用最简单的处理工艺满足回用要求。具体需要选择哪一类处理系统，除了用水系统的要求外，主要取决于废水的水质。
火力发电厂的用水系统一般由生产用水和生活用水两部分构成。生产用水按 用途和工艺流程分为循环冷却水、工业用水、化学除盐水、输煤用水、除灰渣用水等系统；非生产用水通常包括厂区生活用水。
（1）火电厂的循环冷却水水质虽低于锅炉补给水，但若冷却水水质不好，会造成冷却系统管道和设备结垢、腐蚀和微生物滋生，导致系统的热传导性和严密性降低，设备出力下降，严重时甚至会发生故障，影响电厂经济运行和安全生产。
（2）火电厂工业用水通过工业水泵由循环水系统而来，主要是用于厂房内辅机设备、高温取样架、制氢站、除灰输送风机及各车间转机设备冷却，使用后一般可回用至循环水系统，常规的工业水系统冷却水一般分为直接冷却水和间接冷却水，其中，直接冷却水可用于直接和热介质接触通过热交换以达到冷却目的，其水质要求应为低温，无杂质，不腐蚀设备。而间接冷却水是通过热交换器换热来达到冷却目的，并不与热介质直接接触，故其不受热介质污染。间接冷却水的水质要求不高，只需用水对换热器的热管无腐蚀，不结垢。
（3）化学除盐水系统用水一般来源千深井水或者河水等水质较好的源水，也可来 源千如经过反渗透等工艺处理后的循环冷却水排污水等，其原水经过处理后主要 作为锅炉用水的补水。化学除盐水系统为锅炉、氢站、炉内采样冷却、溶药和精处理再生等单位供水，最终的去向主要表现为锅炉汽水损失、锅炉排污损失和再生废水。在疑汽器发电厂中，锅炉补给水董的多少取决于锅炉排污量和系统汽水损失水董的多少。锅炉的排污量因机组情况的不同而异，锅炉汽水损失主要包括排汽损失和一些热水的蒸发损失等。一般相当于锅炉蒸发量的5-7%。此外，化学除盐系统自用水量也不容忽视，一般自用水损失量大小与水处理的方式有关，一般包括反洗、再生设备时产生的酸碱废水以及过滤器反洗排水等。
（4）火电厂生活、消防用水系统来水一般取自水质较好的深井水或者湖泊、河流来水以及市政给水系统等，一般用于洗澡、冲厕等电厂人员用水。
具体的，本实施例中，所述第一水处理单元包括有循环水及排污水减量单元、反渗透浓水减量单元、酸碱废水减量单元和其他废水减量单元。
进一步的，本实施例中，第二水处理单元包括有循环水及排污水复合利用单元、反渗透浓水复合利用单元和其他水复合利用单元。
所述监测平台100包括有数据处理模块120、模型调用单元130、数学求解模块140和数据收发模块110，数据处理模块120、模型调用单元130、数学求解模块140均与数据收发模块110连接，在节水分析过程中，从数据处理模块120中选择数据，从数学求解模块140中选择算法，从模型调用单元130中选择模型，然后将数据、算法、模型结合起来进行问题求解，输出结果并进行决策制定，解决水处理系统200中水处理问题。
所述数据收发模块110包括有人机交互界面111和决策制定单元112，人机交互界面111和决策制定单元112相连接。
所述数据处理模块120包括有数据分析单元122、数据管理模块123、数据存储单元121、数据字典124和数据查询模块125，数据分析单元122与数据管理模块123、数据存储单元121相互连接，数据管理模块123还与数据字典124和数据查询模块125相互连接，数据字典124和数据查询模块125相互连接。
具体的，本实施例中，数据字典124还分别与人机交互界面111、模型调用单元130相互连接，模型调用单元130与人机交互界面111均与数学求解模块140相互连接。
所述模型调用单元130包括模型建立单元131、模型管理单元132、模型字典134和模型库133，模型管理单元132分别与模型建立单元131、模型库133连接，模型库133与模型字典134相互连接。
具体的，本实施例中，所述模型建立单元131还与人机交互界面111相互连接，人机交互界面111还与数据处理模块120相互连接，数据处理模块120还与数学求解模块140相互连接。
所述数学求解模块140包括有方法管理模块141、方法字典142和方法库143，方法管理模块141与方法字典142、方法库143相连接。
具体的，本实施例中，所述方法管理模块141还与数据处理模块120相互连接，数据处理模块120与模型调用单元130相互连接，人机交互界面111还与模型调用单元130相互连接。
需要说明的是，作为火电厂节水方法计算的模型调用渠道，模型调用单元130存有多种数学模型，例如，排污量 P 3与浓缩倍率 K之间的关系。
P 3=[ P 1+ P 2(1- K)]/ ( K-1)
式中： P 1为蒸发损失率； P 2为风吹损失率； K为浓缩倍率。
在火电厂循环式冷却系统的中水多次使用后其中杂质浓度提高，导致循环式水质变差，为保证机组的安全与经济运行，循环供水冷却系统都需要不断排水并补充新水，排放的水即为循环水排污水，循环水排污量一般占循环水补充量的15-70%。
还有，循环水系统作为火电厂用水量最大的水系统，包括有蒸发损失，风吹损失以及排污损失，模型调用单元130还包括有冷却塔的蒸发损失计算模型。
P 1= Z*Δt（%）
式中： P 1为蒸发损失率； Z为与环境温度有关的系数；Δt为冷却塔进出口水温差。
数据处理模块120由数据库管理系统负责管理和维护节水分析系统中使用的各类数据，在模型运行的过程中所使用的数据，按其数据内容分类存储，分别建立数据仓库文件；运行的结果所产生的各种决策信息，常以报表或图形形式存放在数据库中，并增加时间维度来实现数据库的动态连续性；通过数据库管理系统有效地实现与模型库、方法库、知识库与用户接口部件方便、快捷的联结，实现数据的有效输出，以达到为各种决策服务的目的。
模型调用单元130是模型的集合，它按照一定的组织方法，将模型有机地汇集起来，由模型库管理系统统一管理，模型库需要模型库管理系统来建立、运行、维护、交互，模型库管理系统为用户提供有关模型属性的特征信息，便于用户正确地使用模型，对模型的运算结果做出正确的判断；指导用户迅速准确地查找到有关模型，了解模型及其输入输出参数的相关信息；为用户新增模型的源代码和可执行代码的修改以及模型的调用提供相关信息；类似于数据库管理，模型属性库的管理包括模型属性的增加、删除、修改、查询以及新库的创建等操作。
