Condenser dense rubber ball online cleaning device
     

.5 %-- 2.5 %, 对经济性影响非常大 ,因此凝汽器都需要在线清洗,以清除污垢,减小传热热阻。 Every time the end difference of the condenser is reduced by 1 ℃, the coal consumption for power generation will increase by 1.5 % -2.5 %, which has a great impact on the economy . Therefore, the condenser needs to be cleaned online to remove dirt and reduce heat transfer heat. Resistance. 0 - 20%管子数量的胶球装入球罐 用泵将胶球打入循环水总管 一起进入凝汽器端部水室 随机分配达到各个管口 依靠水力通过管子内孔 对管壁进行擦洗 从而去除污垢 The most common online cleaning method for condensers is the cleaning of rubber balls. Put 10 to 20% of the number of tubes into the ball tank . Use a pump to drive the rubber balls into the circulating water main and enter the water chamber at the end of the condenser. It is randomly distributed to reach the mouth of each pipe , and the water is passed through the inner hole of the pipe to scrub the pipe wall to remove dirt . 然后再进入凝汽器循环使用 The rubber ball discharged with the circulating water is collected by the ball collecting device , and then enters the condenser for recycling . 这样的胶球清洗虽然有较好的效果 但总有一些管子 Practice has proved that although such rubber ball cleaning has better results , there are always some tubes ,而且存在逐渐增多的趋势, 只好在停机时人工清洗 Without cleaning for a long time , it will fail , and there is a gradual increase, so we have to manually clean it when it is stopped .

是胶球密集度低 The main reason for the poor cleaning effect of rubber balls is the low density of rubber balls . 一两千只胶球分散其中 很难保证分布的均匀 此有些管子过度清洗 有些管子得不到清洗 The end of the condenser is a huge space . One or two thousand rubber balls are dispersed in it . It is difficult to ensure uniform distribution . Therefore, some pipes are over-washed and some pipes are not cleaned . 研究开发了密集胶球的在线清洗装置 利用原来的胶球系统 只是在凝汽器端部水室内 安装了平面扫描机构 对每个区域进行扫描 将密集的胶球输送到扫描区域 保证该区域的胶球数量多于管口数量 , 每根管子获得胶球的概率大大提高 使每根管子都得到清洗 In response to this problem , Hangzhou Dika Company researched and developed an on-line cleaning device for dense rubber balls . Using the original rubber ball system , only a flat scanning mechanism was installed in the water chamber at the end of the condenser , and each area was scanned to densely The rubber ball is transported to the scanning area to ensure that the number of rubber balls in this area is greater than the number of nozzles . The probability of obtaining a rubber ball per tube is greatly increased , so that each tube is cleaned . 不影响原来胶球清洗系统的使用 改造小 没有任何副作用和风险 The device only bypasses the original rubber ball scoring tube , does not affect the use of the original rubber ball cleaning system, and has a small modification without any side effects and risks .

00MW机组的凝汽器 一般有 4个室,每个室有9 000多根冷却管 , 每台机组 一套胶球系统 切换使用 The condenser of a 600MW unit generally has 4 rooms, each room has more than 9,000 cooling pipes , and each unit is equipped with a rubber ball system , which can be switched . 就要在每个室的进水端 安装 1套扫描式密集胶球清洗装置,因此需要4套,通过阀门切换。 If intensive rubber ball cleaning and transformation is carried out , a set of scanning type dense rubber ball cleaning device must be installed at the water inlet end of each chamber , so 4 sets are needed, which are switched by a valve.

.
Features of the dense rubber ball online cleaning device:


▲ The tee is enriched with rubber balls , the number of rubber balls is higher than the number of nozzles , and the probability of passing the ball is greatly increased ;

▲ The servo motor and the chain transmission mechanism realize plane scanning without omissions and dead angles.
