第一章胶球清洗系统布置和安装
ChapterⅠLayout and Installation of Gum Ball Cleaning System
一、胶球清洗系统布置方式有两种
Ⅰ. There are two layout ways of gum ball cleaning system
1、单元制系统Modular system
1、排污口2、清洗蝶阀3、二次滤网4、装球室5、球阀6、胶球泵7、收球网8、收球网板操作机构.
1. Outfall 2, Cleaning valve 3, Secondary screen 4, Ball room 5, Ball valve 6, Gum ball pump 7, Ball screen 8, Ball net plate operating mechanism.
2. Sharing system
2、共用制系统Common control system
1、排污口2、清洗蝶阀3、二次滤网4、电动机5、收球网6、装球室7、球阀8、胶球泵9、分汇器.
1. Outfall 2, Cleaning valve 3, Secondary screen 4, Motor 5, Ball screen 6, Ball room 7, Ball value 8,
Gum ball pump 9, Sub-exchange device.
胶球清洗系统安装应遵照供货单位提供的系统布置图和技术要求进行安装,不可随意增减系统中的相对位置.
The installation of gum ball cleaning system shall be subject to system layout diagram and technical requirements provided by supply unit, prohibit increase or decrease the relative position of the system arbitrarily.
二、不同布置方式的适用范围:
II. The scope of application of different layout:
a、单元制系统,适合于为100MW以上容量的机组配套使用.优点是对凝汽器各侧可同时进行清洗;另外,任何一侧的胶球清洗系统出现故障,均不会影响另一侧的正常运行.
b、共用制系统,适合于小机组使用.优点是设备少,主要缺点是当系统中共用部分发生故障时,凝汽器的任何一侧都无法清洗.
a. Modular system is suitable with the units of over 100MW. Advantage is that each side of condenser can be cleaned at the same time; Moreover, any side of the gum ball cleaning system broke down, which will not affect the normal operation of the other side.
b. Sharing system is suitable for use in small units. Advantage is less equipment, and the main drawback is that when the common parts of the system broke down, any side of the condenser can not be cleaned.
第二章设备安装
Chapter II Equipment Installation
收球网:Ball screen:
收球网尽量采用立式安装,并且收球网胶球引出管尽量高于胶球泵入口.
收球网在循环水管弯头后很近处安装时,应使操作轴与弯头方向相平行;对SD型收球网最好采用操作轴与弯头方向相垂直的布置方式,且在收球位置时,网板进口端靠在内侧筒壁.收球网若采用卧式布置时,胶球引出管应按要求在收球网底面或侧面.
Ball screen adopts vertical installation as far as possible, and ball screen gum ball extraction tube shall be higher than gum ball pump.
When installing the ball screen closed to circulating water pipe elbow, they should make the operation shaft run parallel to the direction of elbow; about SD-type ball screen, preferable to use the layout of operation axis perpendicular to the direction elbow, and in the position received the ball, head of the halftone leaning against the inner tube wall. If the ball screen adopts horizontal layout, the gum ball extraction tube should bet at the bottom or the side of the ball screen as required.
胶球泵:Gum ball pump:
胶球泵安装的相对位置不宜过高,以防气蚀.胶球泵的吸上真空高度一般为7m水柱.
The relative position of gum ball pump should be not too high to prevent gas etching. The vacuum suction height of gum ball pump is generally the water column of 7m.
装球室:Ball room:
用于贮存、更换胶球及观察胶球运动,故安装位置应便于操作人员接近,放气、放水管接至排水地沟.
For use of storage, replace of gum ball and the observation of gum ball’s movement, so the installation location should be accessible to the operator, exhaust tube and offlet connected to the drainage trench.
胶球管路及阀门:Gum ball piping and valves:
胶球管路应短直流畅,球阀或蝶阀安装位置应便于操作,装球室进口阀在装球室的进口处安装,管系严密不漏.
Gum ball piping should be short, straight and smooth. The installation location of ball valve or butterfly valve should be easy to operate. Suction valve shall be installed on the entrance of ball valve. Piping shall be tight and no leaking.
循环水系统中安装有二次滤网时,一般情况下,二次滤网出口至凝汽器间,循环水的长度有限,但布置投球管时,应遵照以下原则,且不可在凝汽器水室中布置.
When installing the secondary screen in circulating water system, generally, the circulating water is limited in length from the outlet of the secondary screen to the condenser, but arranging pitch pipes shall be subject to the following principles, and can not do in water room of the condenser.
循环水管通径DN<1200时,投球管(伸入循环水管中的胶球管路)用一根,并伸至循环水管中心,DN≥1200mm时,用两根并在循环水管同一正截面内对称布置,两管口中心在循环管同一直径上,管口间距离等于循环水管半径,投球管出口逆循环水流方向.
When the circulating water pipe diameter DN <1200, the pitch pipe (the gum ball piping stretching into the circulating water pipe) adopts one, and extended to the center of circulating water pipe. When DN ≥ 1200mm, use two to parallel in the same section of the circulating water pipe with symmetrical arrangement, centers of the two nozzles in the same diameter of the loop pipe, the distance between the nozzle is equal to the radius of the circulating water pipe, and the outlet of the pitch pipe opposes circulating flow direction.
控制装置:Control device:
控制柜或程控柜,应在通风、干燥、且靠近装球室处安装.
Control cabinets or program-controlled cabinets should be installed in ventilated, dry, and close to the ball room.
二次滤网:Secondary screen:
配装有二次滤网的胶球清洗系统中,二次滤网的安装部位,一般情况下应离开凝汽器进口一段距离,这样对于投球管的布置有利.以海水为冷却水源的电厂,二次滤网宜靠近凝汽器进口布置,以便减少二次滤网后循环水管中海生物的数量,从而减少冷却管、收球网被堵塞的机会.二次滤网的排污管路应短直流畅,尽量减少管路水阻,因为二次滤网排污是依靠循环水压差来实现的,故排污水阻大时会直接影响排污效果.
In the gum ball cleaning system with the secondary screen, the installation position of the secondary screen should keep a distance from the entrance of the condenser, so that it’s favorable for the arrangement of pitch pipe. Regard the seawater as the cooling water plant, the secondary screen should be close to the entrance of the condenser in order to reduce the number of sea creatures in the circulating water pipe after the secondary screen, thereby reducing the opportunities of the blocked cooling pipe and ball screen. The blow-off line of the secondary screen should be short, straight and smooth, minimize the water resistance of piping, as the secondary screen scavenging relies on recycled water pressure to achieve, the large sewage water resistance will affect effects of sewage directly.
胶球清洗系统的安装,应按照制造厂提供的系统布置图和技术要求进行,不可随意增减系统中配套件的数量和改变设备配套件的数量和改变设备配套件在原系统中相对位置.
The installation of gum ball cleaning system should be in accordance with layout diagram and technical requirements provided by factory, prohibit increase or decrease the number of component parts and the relative position of the system arbitrarily.
