1、除二氧化碳器Instruction for Decarbonator使用说明书Operation Instruction Manual无锡电站辅机厂Wuxi Power Auxiliary Equipment Works一、用途除二氧化碳器是用于驱除在水中的软化，除盐过程中，原水经过氢离子交换后，水中的 重碳酸被破坏而产生的大量游离二氧化碳的设备，它设置于氢离子之后。可以去除水中的二氧化碳，减少对设备的腐蚀，减轻阴离子交换的负荷，提高水处理设备系统的经济性与出水 水质。二、主要技术数据工作压力：常压工作温度：常温淋洒密度：60米3/米2时进水温度：15c进水CO2含量： 390毫克/升出水CO

2、2含量： 5毫克/升三、工作原理当含有H2CO3的水通过进水装置均匀地从容器顶部往下流过填料层时，水在填料的表 面形成一种薄膜的流动，薄膜的流动造成了水中CO2和容器底部鼓进来的空气密切接触的条 件，使水中气体与空气中气体容易自由交换， 由于空气里的CO2含量很小，它的压力只占大 气压力的0.003%左右，所以，水中的CO2就很容易扩散到空气里去，当水逐渐往下流动时， 它所接触的却是比较新鲜的空气（因空气向上流动，越到容器上部，空气里吸收的CO2越 多.“新鲜”指空气中所吸收的 CO2较少）更有利于CO2扩散出来，水流至底部时，水里的绝大 部分CO2已被去除，残余的CO2含量在5毫克/升左右。

3、四、结构简述1 .进水装置：采用支管式结构，用硬聚氯乙稀管或不锈钢管制作。2 .多孔板及填料：多孔板：小直径设备上采用硬聚氯乙稀板制作，大直径设备上采用钢板衬胶。填料：采用25X25X3陶瓷环或50聚丙烯塑料空心多面球。3 .进水管管径的选择按2米/秒流速考虑。4.本产品可根据用户不同的水质情况，按下表选取不同的填料层高度。编号12345含 CO2mg/l<25< 44.3<76.4<164<392.3填料高度（mm）16002000250032004000五、使用方法1. 启动和供水(1) 启动清水泵，开启投运的阳离子交换器运行进水门和空气门，待空气放尽关闭空气

4、门。开启该交换器疏水门，顺流至水质符合规范，并检查没有跑树脂现象以后，即开启鼓风机，然后关闭疏水门，开启阳离子交换器出水门向除碳器进水，进行除碳工作。(2) 水位到达中间水箱正常水位时，开启中间水泵、向阳离子交换器供水，严格监视中间水箱水位，以保持阴、阳离子交换器的流量平衡，防止水箱溢流和中间水泵打空泵。2. 停止供水和停用(1)停止供水顺序是：停用阴离子交换器-停用中间水泵-停用阳离子交换器-停用清 水泵-停用除碳器鼓风机。(2) 阴、 阳离子交换器切换时，应事先启用投运的交换器，然后关闭停用的离子交换器。六、安装1. 填料在运输过程中可能掺有污泥，杂质及破碎情况，应以于清洗及去除后方可装入

5、筒体。2. 除碳器所装塑料空心多面球的规格和高度应符合设计要求，填料应尽量保证完整，减少破碎情况。3. 将填料装入筒体时，可先在筒体内注入一定高度的水，然后再将填料倒入，这样可减少填料的破碎。4. 设备总装完毕后，除碳器所有构件的连接处，均应接合严密，不得有渗漏现象。七、维修保养1. 设备装置于室外的，应定期涂刷防锈漆，以防止设备腐蚀，延长设备的使用寿命。2. 由于设备内部装有塑料部件及筒体衬胶，因此设备发运至使用单位而不立即使用者，应将设备放入室内存放，其环境温度应是530C,室温低于5c应考虑保温措施，防止塑料及胶层的损坏，严禁在露天存放。3. 设备检修时，检查内部填料的破碎程度，根据实际

6、情况，应调换或添加以保证除碳效果。八、供货范围供应除二氧化碳器本体及配套风机。I. ApplicationThe decarbonator, equipped after H-ion exchange, is an apparatus used to remove a large amount of free CO2 produced while the high carbonic acid in water was destroyed after the raw water was exchanged with H-ion in course of the softening and des

7、alting water. The CO2 in water could be removed, resulting in reducing the collision to the equipment and the load of the anion exchanger and increasing the economy and outlet water quality of the water treatment system. II. Main Technical PerformanceWorking pressureWorking temperatureLeached densit

8、yInlet water temperatureordinary pressureordinary temperature60m3/m2 x h15Amount of CO2 in inlet water < 390mg/LAmount of CO2 in outlet water < 5mg/LIII. Working principleWhen the contained H2CO3 flow downward through the filler layer uniformly from the top of tank via intake apparatus, it wil

9、l form a kind of film flow on the surface of the filler. The formed film creates a condition for the CO 2 in water to come into closely with the air blown in from the bottom of tank and thus it makes the gas in water and that in the air exchange easily and freely. Sine there is little CO2 in air who

10、se pressure is about 0.003% of atmospheric pressure, the CO2 in water is spread out easily in the air. When the water flow downward gradually, what it contacts is fresher air (since air flow upward the higher it flow, the more CO2 the air intakes, the “ fresh means the air intakes less CO2) which is

11、 mosst advantageous for the CO2to spread out. Most CO2 in water has been removed while the water flow to the bottom and remained CO2 is less than 5mg/L.IV. Structure Specialty1. Intake apparatus: Branch type construction fabricated with high polyvinyl chloride is adopted2. Porous plate and filling m

12、aterial:High polyvinyl chloride plate is adopted for small diameter equipment . Steel plate rubber lining is adopted for large diameter equipment.Filling material： 25X 25X3 ceramic ring or polyacry plastic hollow polyhedral ball is adopted.3. The diameter of the intake tube is opted based on the flo

13、w speed of 2m/s.4. The height of filling material for the equipment may be opted based on the water quality ofuser as following table.Number1 一2345CO2 content (mg/l)<25<44.3<76.4<164<392.3Height of filling material (mm)16002000250032004000V. Operation1. Start and water supply(1) The c

14、lear water pump is started and the reserved cation exchanger, operating intake door and air door are opened. The air door should be closed when the air is exhausted out. The drainage door of the exchanger should be opened and the water will be washed till the quality conforms to the specification. A

15、fter the case of the escaping resin is inspected, the blower is started and then the drainage door is closed and the outlet water door of the cation exchanger should be opened to feed water to the decarbonator. Thus, decarbonating proceeding will be carried out.(2) Medium water pump should be operat

16、ed and water will be feed to the cation exchanger when the level is up to the normal level of the medium water tank. The water level of the medium water tank should be inspected carefully, to keep the flow balance of the anion and cation exchanger and to avoid overflowing of the water tank and pumpi

Stop feeding water and stop operating(1) The steps of stopping feeding:Stop operating anion exchange 什 stop operating medium water pum尸 stop operating cation exchanges stop operating clear water pump> stop operating decarbonator blower.(2) The reserved excha

18、nger should be used first before operating for the anion and cation exchanger. And then the unused ion exchanger should be closed.VI. Installation1. The filling material possibly mingle with mud and impurity during transport process, It should be washed with clear water prior to it is put in tank.2.

19、 The size and height of filling material in the equipment should conform drawing requirements, and the plastic hollow polyhedral should be integral, the fragmental ball should be reduced.3. When put the filling material in the tank, should fill the tank with water to proper height then put the filli

20、ng mater in the tank to reduce filling material fragment.4. All the interfaces of parts in the equipment should be compact jointed and leakage is forbidden after installationVII. Maintenance1. All those equipmentsshould be coated periodically with rust resistant paint to make the equipment long-service life.2. Since the plastic parts and shell rubber lining a
