Description

一种核电站除盐水系统除总有机碳的系统及控制方法 One kind of nuclear power plant control system and a method for total organic carbon in addition to other brine systems

技术领域 FIELD

[0001] 本发明涉及核电站除盐水处理系统领域,特别涉及一种核电站除盐水系统除总有机碳的系统及控制方法。 [0001] The present invention relates to water desalination systems of nuclear power plants, and more particularly, to a nuclear power plant control system and a method of demineralized water systems other TOC.

背景技术 Background technique

[0002] 核电站除盐水系统的功能是处理原水预处理系统来水,通过蒸馏、反渗透、离子交换或这些方法的结合去除经过原水预处理后的清水中的溶解盐,得到一级除盐水,然后一级除盐水通过混床得到满足机组要求的除盐水。 [0002] In addition to nuclear power system is a processing function saline water pretreatment system runoff, by distillation, reverse osmosis, ion exchange or a combination of these methods to remove water through the water treatment process after the dissolved salts, to give an addition salt, then demineralized water to give a desalted water satisfies the requirements set by the mixed bed. 水中有机物质的含量,以有机物中的主要元素-碳的量来表示,称为总有机碳(以下简称T0C)。 The water content of the organic substance, the organic substance to the main elements - the amount of carbon to said called TOC (hereinafter referred T0C).

[0003] 文中所述AP1000是一种先进的非能动型压水堆核电技术(以下简称AP1000),采用铀制成的核燃料在“反应堆”的设备内发生裂变而产生大量热能,再用处于高压下的水把热能带出,在蒸汽发生器内产生蒸汽,蒸汽推动汽轮机带着发电机一起旋转发电。 [0003] The AP1000 is described in an advanced pressurized water reactor nuclear power technology passive type (hereinafter referred AP1000), use is made of uranium fuel occurs in the "reactor" fission device generates a lot of heat, and then at a high pressure the thermal energy of water out of the steam is produced in the steam generator, the steam turbine driven generator to rotate together with the power generation.

[0004] 核电站除盐水处理系统是AP1000核电站重要的辅助系统之一,其作用等同于火电厂的锅炉补给水处理系统。 [0004] nuclear power plant desalination water treatment system is one of the important AP1000 nuclear power plant auxiliary systems, its role is equivalent to the boiler feed water treatment system in thermal power plants. 除盐水处理系统产水水质控制指标主要有导电度、硅酸根含量、TOC等,其中TOC在核、火机组上的控制区别很大。 Desalting produced water treatment system control main index conductivity, silicate content, TOC, etc., where a big difference between the control TOC on the core, the fire unit. AP1000核电站对除盐水中TOC指标的控制远远高于火电机组,其中AP1000要求TOC ( 50ppb,火电厂高压机组要求TOC ( 500ppb且仅在必要时监测。这就对核电站除盐水处理工艺设计提出了更高要求。 AP1000 nuclear power plant control for water desalination TOC index is much higher than thermal power, which requires AP1000 TOC (50ppb, high-pressure thermal power plant unit requires TOC (500ppb and monitored only when necessary. This desalination water treatment process design for nuclear power plants proposed higher requirements.

[0005] 在实现本发明的过程中,发明人发现现有技术至少存在以下问题: [0005] During the implementation of the present invention, the inventors found that the prior art has at least the following problems:

[0006] 1、除盐水处理系统产水TOC含量受制于水源水质 [0006] 1, desalination water system subject to the TOC content product water quality water

[0007] 目前国内在建的AP1000核电站的除盐水处理系统主要工艺都是采用反渗透(以下简称R0)与离子交换除盐相结合的方法,延续了火电厂的锅炉补给水处理工艺,除AP1000核电站外,其他核电站或火电站都没有特别提出去除TOC的工艺要求。 [0007] Currently AP1000 nuclear power plant under construction in the main process of desalination water treatment systems are reverse osmosis (hereinafter referred to as R0) desalination method in combination with ion exchange, continuing a thermal power plant boiler feed water treatment process, in addition AP1000 outer nuclear power plants, nuclear power plants or other power plant are not particularly made of TOC removal process requirements. 因此要求水源中TOC含量维持在5ppm,受制于水源情况,无法通过现有工艺解决,在核电厂建设中几乎难以达到。 Thus requiring water TOC levels maintained at 5ppm, subject to the water source, can not be resolved through the existing process, almost difficult to achieve in the construction of nuclear power plants.

[0008] 2、除盐水处理系统TOC去除率不稳定 [0008] 2, desalination water treatment system instability TOC removal

[0009] TOC是一个综合指标,其成分非常复杂,细菌、微生物、生化需氧量(B0D)、大分子有机物等都属于T0C,而采用反渗透+离子交换除盐方法对不同组成的TOC去除率是不同的,若TOC中大分子有机物占的比例较高,则去除率较高,反之去除率较低,TOC去除率不稳定,故而影响核电站热力系统稳定运行。 [0009] TOC is a composite indicator, which composition is very complex, bacteria, microbes, biochemical oxygen demand (B0d), organic molecules belong T0C, while the use of reverse osmosis desalination + ion exchange method of removing TOC different compositions rates are different, if the TOC higher proportion of organic molecules, the higher removal rate, the removal rate is low and vice versa, TOC removal instability, and therefore affect the nuclear power plant thermal stability of the system.

[0085] 综上所述,本发明实施例二的控制方法关键在于紫外线消毒设备3的位置及紫外线(UV)波长的选择。 [0085] In summary, embodiments of the present invention is that the method of controlling the key position and the UV disinfection device ultraviolet (UV) 3 wavelength selection. 若将紫外线消毒设备3设置在反渗透装置2之前,会由于悬浮物、胶体对紫外线的干扰,造成UV杀菌率降低,造成系统出水水质达不到要求;若将紫外线消毒设备3设置在后续水处理设备5之后,则会造成分解产物直接进入热力系统,变相给热力系统引入了杂质。 If UV disinfection device 3 is disposed before the reverse osmosis unit 2, due to suspended solids, colloids UV interference, resulting in reduced UV sterilization rate, causing the system mainly the water quality; if UV disinfection of water in a subsequent 3 after the processing apparatus 5, it will cause thermal decomposition product directly into the system, to disguise the impurity introduced thermodynamic system. 通常消毒用紫外线波长选用284nm,该波长能对细菌等生命体灭活,但失去活性的细菌等仍是T0C,并没有去除,通过合理选择UV灯管的波长及数量,保证合适的介质流速,使除盐水处理系统产水直接将细菌等活性或非活性有机物分解,去除T0C。 Disinfection is usually chosen with 284nm ultraviolet wavelengths, the wavelength can inactivate bacteria and other living, but the inactivated bacteria is still T0C, and not removed, by properly selecting the number and wavelength UV lamp, the flow rate to ensure a suitable medium, desalting yield water treatment system so that the bacteria directly active or inactive decomposition of organic matter, removing T0C.

[0086] 本发明实施例充分利用现有设备,通过合理的设计工艺,梯度处理理念,提高了核电站二回路汽水品质,有效的保证核电站长期、高水平运行,经济效益显著。 Example [0086] The present invention fully utilizes the existing equipment, through rational design process, the concept of the gradient process, improve the quality of the Secondary Circuit soda, nuclear power stations to ensure long-term effective, high-level operation and significant economic benefits.

[0087] I)直接经济效益 [0087] I) direct economic benefits

[0088] 采用RO + UV的除盐水处理系统,其出水TOC含量不受水源影响,避免了产水由于TOC不合格而浪费。 [0088] The RO + UV water desalination system water effluent TOC content is not affected, since the TOC avoids the unacceptable production of wasted water. 按照I台AP1000核电机组年运行7000h、每小时消耗除盐水70t计,假设全年有十分之一的时间受季节影响造成水质不合格,则会浪费70t/h X 7000h/10=49000t除盐水。 According to Taiwan I AP1000 units in operation 7000h, consumption of demineralized water 70t meter, assuming one tenth of the time throughout the year due to seasonal impact of substandard water quality, waste will be 70t / h X 7000h / 10 = 49000t demineralized water per hour . 采用RO + UV系统后,则可避免此部分损失,按除盐水制水成本5元/t计,每年产生直接经济效益24.5万元。 With RO + UV systems, the loss can be avoided in this section, in addition to the cost of water by saline 5 yuan / t count, generating direct economic benefits 245,000 yuan per year. [0089] 2)间接经济效益 [0089] 2) indirect economic benefits

[0090] 采用RO + UV系统后,供给AP1000核电站的除盐水中TOC含量极低,最大可能减少了TOC分解造成的蒸汽发生器腐蚀,从而延长了电厂寿期;避免了由于水质不合格造成的非正常停机等,这些间接经济效益无法估量。 After [0090] The RO + UV systems, desalination TOC content of the water supplied AP1000 nuclear power plant is very low, the maximum possible to reduce the TOC decomposition caused by corrosion of the steam generator, thereby extending the life of the plant; avoided because the water is caused by unqualified non-normal shutdown, etc. these indirect economic benefits incalculable.

[0091] 3)节约用水 [0091] 3) water conservation

[0092] 采用RO + UV的除盐水处理系统避免了产水浪费,从而节约了水源地取水。 [0092] The desalination RO + UV water treatment systems to avoid the production of waste water, thereby saving water source water.
