Tow-Bro技术优势(中英文).doc

Tow-Bro单管式吸泥机技术优势一 世界领先的技术Tow-Bro单管式吸泥机是美国U.S.FILTER公司拥有的专有技术，授权国美（天津）水务设备工程有限公司在中国独家制造，并达到美国U.S.FILTER公司的质量和标准。Tow-Bro单管式吸泥机与周边进水周边出水二沉池（Rim-Flo）工艺配合使用，更能体现工程造价的经济合理。二 先进的工艺设计1 Tow-Bro单管式吸泥机是依据水力学理论和二沉池底部污泥特性，采用异型管结构制成的吸泥装置，它的吸泥管在整个池底按比例地均匀收集污泥，与其它传统的立管吸泥机相比，可获得较高的污泥吸除效果。2 由于排泥管的设计符合二沉池底部污泥水力分布特性，可使二沉池排泥浓度提高20%-30%，从而提高生物反应池的污泥浓度，大幅度提高生化反应效率和污泥脱水效率，减小池容，降低工程造价，同时也减少了日常的运行耗电费用。3 电脑设计的单管式吸泥机能够迅速、均匀吸取二沉池内絮凝状污泥。在数百个系统及在测试中已得到证实的独特设计确保实效，操作简单，维护要求少，并能大大减少建设和能源消耗费用。三 先进的工艺特点：1.吸泥迅速利用电脑设计的单管吸泥机确保准确、迅速地将沉淀的污泥吸除。这一干净利落的作业可保证全池污泥成层沉淀提高污泥通量。这种快速吸泥方法可确保无长时间沉积污泥、积腐少、提高生物活性、降低生物池供氧量并能防止磷酸盐的释放和污泥反硝化膨胀上浮。2.污泥浓度高由于首先清除的是池底未搅动部分的污泥，因此保持了回流污泥的足够浓度，使回流及剩余污泥液体流量减少，从而减少了泵水的需要。由于污泥未被稀释及液体量降至最低，曝气池和污泥处理系统的设计和运行，都可减至最少。3.最小污泥搅动吸泥管的缓和平稳的吸泥作业减少了将沉积污泥再悬浮及往上浮出水面的机会。水池下层的搅动降至最低，避免了污泥的稀释，提高沉淀效率。4.平衡的水循环设计由于污泥层均匀地覆盖着整个池底，吸泥管和管上的吸泥孔必须根据每孔吸泥面积的比例吸除沉积污泥。Tow-Bro吸泥机适用于广泛的流量，可确保污泥层最薄，保持较清的出水。5.经济由于池底是水平的，无须另配斜坡池底和专门的污泥斗，土建投资省。好的污泥质量意味着需氧量低，减少了系统能耗。同时由于没有了刮泥和挖泥的过程，扭矩要求也小于其它吸泥机，使之更为节电。6.灵活的运行和维护与其它大多数类型的吸泥机相比，Tow-Bro吸泥机结构简单。通过压力或重力由一个阀门控制污泥排出，这种方法在所需排泥速度发生变化时具有明显优势。单阀控制可以方便调整污泥回流量，使得二沉池易于满足工艺变化的条件。与其它吸泥机相比，不存在堵塞现象，因此，很少需要维护。电脑设计的单管式吸泥机能够迅速、均匀吸去二沉池内絮凝状污泥。在数百个系统及在测试中已得到证实的独特设计确保实效，操作简单，维护要求少并能大大减少建设和能源消耗费用。四 先进的配套部件1专用的回转支承及带有过载保护装置的驱动组合美国U.S.FILTER公司具有75年二沉池理论与实践研究之精华和遍布全球的2500台以上的优良运行经验。采用了美国U.S.FILTER专门为二沉池中心传动单管式吸泥机设计及制造的回转支承、驱动装置及过扭矩保护装置的原装进口组合部件，大大提高了转动配合，运行平稳，安全可靠，使用寿命长。2先进合理的结构件设计整套设备全部由美国U.S.FILTER公司采用先进的力学软件优化设计，结构受力合理，整机重量较轻，使用寿命长。工作桥采用固定半桥式桁架结构，与其它刮吸泥机工作桥相比，重量较轻，刚度好，外形美观。五 成功的运行业绩Tow-Bro单管式吸泥机在国内已有直径48M和峰值负荷1.55m3/m2h 的周进周出二沉池成功运行业绩。在国外已有直径60M和峰值负荷2 m3/m2h 的周进周出二沉池成功运行业绩。出水SS均不高于20mg/L。六完善的培训计划、郑重的质量承诺1. 为了更好的完成设备的供货、安装、调试、试运转及保证设备的长期正常的运转，我公司可提供完善的培训计划。2. 为使业主放心使用，我公司对产品质量及售后服务作出了郑重承诺。七按期交货、按期完成安装调试我公司采用世界先进的工程项目管理软件及管理方法实施各项目，严格执行ISO9001系列质量管理，保证产品的出厂质量和项目的按期完成。The Advanced Technologies of TowBro Uni-tube Sludge CollectorI.The Leading Technology in the WorldThe patent of TowBro Uni-tube Sludge Collector is under the control of U.S.FILTER which authorized U. S. Filter (Tianjin) to exclusively manufacture in China. The quality of the product can reach the standard of U.S.Filter. The cost of engineering is economic optimum because of the combination of Tow-Bro uni-tube sludge collector and Rim-flo clarifier.II.Advanced design 1. TowBro Uni-tube Sludge Collectors are designed according to the hydraulic theories and characters of sludge on the bottom of the clarifier and use headers of special sharp to assure the hydraulic balance required for proportional sludge withdrawal volumes and withdraw greater volumes compared to other ones.2. A header suitably designed increase 20%-30% of the concentration of discharged sludge from secondary clarifiers, thus increases the concentration of the biological tanks to result higher efficiencies of biological recreation and dewatering, in the same time, deduces the housing capacities and the costs of the tanks and lower the routine power of operation consumption.3. The computer-designed Uni-tube sludge collector provides the ultimate in rapid, uniform removal of secondary clarifier flocculent sludge. The unique design, proven in hundreds of installations as well as in exhaustive testing programs, assures effective results, simple operation, less maintenance requirements, and substantial construction and energy cost savings.III.The advantages of the technology:1. Rapid sludge removal Computer-designed Uni-tube sludge collector ensures positive, rapid removal of settled concentrated sludge in one revolution. The revolution is able to suck the solid all over the tank thoroughly. This rapid removal ensures to reduce the settling time and the septic sludge; to raise the activated sludge organisms; to reduce aeration requirement; to prevent of phosphate release and sludge bulking for de-nitrification. 2. Maximum solids concentration Because the undisturbed layer on the tank floor is removed first, the necessary concentration of flow-back sludge required to maintain. The process is returned without unnecessary dilution water. Less pumping is required. Aeration basins and solid handling systems can be designed and operated for the minimums since sludge is not diluted and liquid volumes are reduced.3. Minimum sludge agitation The header design and gentle removal action reduce the chance for the concentrated settled sludge to re-suspend into the upper liquid. There is a minimum of underwater disturbance. Sludge dilution is again avoided.4. Balanced hydraulic design Since a sludge blanket settles uniformly over the entire tank bottom, the sludge collector must remove settled solids in proportion to the area covered. The Tow-Bro sludge collector doses this over a wide range of flows and permits low sludge blankets to be maintained for clearer effluents.5. Economy Since tank floors are virtually flat, there is no need for a separate drain line, sloping floors and special hopper designs. Thus means lower costs for construction. And the superior sludge quality means lower aeration requirements, companied by torque requirements are less than other sludge removal devices-another power saver. 6. Flexible operation and maintenanceCompared to most other types of sludge collectors the Tow-Bro Uni-tube header is simplicity itself. One valve controls sludge withdrawal by pressing or gravity, an important advantage particularly when change in withdrawal rates is required. Single valve allows the final clarifier to be more flexible in meeting changing process conditions. Clogging is nonexistent as compared to other devices. Less maintenance is required. The computer-designed Uni-tube header provides the ultimate in rapid, uniform removal of final clarifier flocculent sludge. The unique design, proven in hundreds of installations as well as in exhaustive testing programs, assures effective results, simple operation, less maintenance requirements, and substantial construction and energy cost savings.IV. Advanced matched parts and components1. Special swing bearing and driving assembly with overload protectionThe U.S.Filter has 75 years history of the theory of research and practice of secondary clarifier and more than 2500 sludge collectors running all over the world. The congregated group of drive assembly, swing bearing, and protection device, and so on, are produced for the Collector by U.S.Filter and intact imported. It improves the rotational cooperation at most, runs stability and safety and has a long life.2. Advanced and reasonable design for structural partsUSFilter used advanced mechanics software to optomize the design of the whole set. The force that the structure can support is reasonal. The whole set is very light and has a long life. Working bridge is fixed semi-bridge and truss structure. It is lighter, better stiffness and more beautiful figure comparing with working bridges of other scrapers and sludge collectors.V.
