This paper intruduce the question about the AHBLG GRP crosscurrent water in a sulphuric acid factory is overfiowed seriously and the water's diversion is out of shape;proposed the improvement plan that made the aperture of the distributive holes in the launder fromφ10 toφ16;After implementation,it has saved 2 millions tons productive used water every year.
介绍了某厂硫酸系统AHBLG全玻璃钢横流式凉水塔漫水严重、分水板变形的问题;提出了将布水槽上布水孔孔径由Φ10扩大到Φ16的改造方案;实施后,每年节约生产用水200万t。
In order to improve the problems from HDT-55 truntable filters, measures are taken as follows:cloth water and distributing trough are rotated clock-wise at 10～15°, athodyd combustion chamber enlarged, filter cloth washing nozzle, ring-shaped pipe material improved.
为了改进HDT-55转台过滤机使用中暴露出的布料布水槽角度不合理、栈桥及支架腐蚀严重、滤布冲洗水喷头易堵、钢衬胶真空环形管易起泡等问题,采取了如下措施:将布水、布料槽顺时针转10～15°,增加吸气室空间,改进滤布冲洗喷头总成,改进环形管材质等。
On the other hand,the design of UASB system must consider the separation of UASB system、three-phase separator、influent distribution system and culture of granular sludge.
上流式厌氧污泥床(UASB)处理PTA污水可取得良好的效果,在工艺设计的过程中需要考虑到PTA污水在事故状态下的收集和污水的水质调节;UASB厌氧系统的设计要注意处理单元的合理划分、布水系统、三相分离器以及污泥培养四个方面的问题。
Once the water distributor on the bottom of UASB is often blocked, when operating in practice,the uniformity of water distribution is destroyed.
厌氧反应器UASB在实际运行中 ,其底部的布水器经常出现堵塞 ,从而造成了配水的不均匀 。
Aiming at the issue of the uniformity of water distribution in indirect evaporative coolers, based on the improvements of structure of water distributors and the selection of water absorbing materials, presents specific measures and conducts some accordingly experimental studies.
针对管式间接蒸发冷却器在工程应用中存在的布水不均匀问题,从布水器结构型式的改进和吸水性材料的选择两个方面着手,提出了具体的措施并进行了相应的实验研究,结果表明可以达到改善均匀布水效果、增大换热器表面润湿系数,进而提高管式间接蒸发冷却器热质交换效率的目的。
Unification of the water distributor and the effect of separation of three-phase .
本文首先论述了课题提出的背景和意义，指出影响升流式厌氧污泥床(UASB)处理效果的因素，其中布水器的均匀布水和三相分离器的分离效果直接影响处理效果。
