泥水分离设备概述 General Description of STP 海瑞克泥水分离设备HSP2800 Herrenknecht Separation Plant, HSP 2800 针对出渣能力和排出渣土特性的波动情况，泥水分离设备在隧道施工过程中的设计要具高度灵活性，以避免隧道掘进机外围系统在施工过程中出现瓶颈现象。 Separation Plants in tunnelling operations have to be designed with the up-most flexibility regarding capacity and muck characteristic fluctuations to avoid a bottle neck for the tunnel boring machine (TBM) operation in the peripheral system. 海瑞克公司开发的HSP系列泥水分离设备，全面支持隧道掘进机的隧道施工， 尤其是与海瑞克公司的隧道掘进机相配套，将更是如鱼得水。 Herrenknecht Separation Plant, HSP was developed to fully support the TBM especially Herrenknecht TBM’s tunnelling progress. 模块式设计 Modular concept 所有主要部件都安置在标准的30或40英尺的集装箱内。人行通道采用宽度为集装箱宽度一半的组件。模块式设计使得对现场面积的要求减到最小，而且方便运输、组建和拆卸。在城市施工环境中，还可以对设备采取噪音隔离措施。 All major components are housed in standard 30 or 40 foot containers. Catwallk units have half container width. The modular concept leads to minimum footprint requirements at site as well as facilitating easy transport, set-up and dismantle. Noise insulation can also be achieved in urban environments. 分离过程 Separation Process 海瑞克公司的泥水分离设备的作用是高效地分离传统泥水盾构或海瑞克公司的混合式盾构机在隧道开挖时所用的膨润土悬浮液。在使用这样的隧道掘进系统时，膨润土悬浮液是作为一种传输流体，用来把隧道掌子面上开挖下来的物料输送到地面，同时还起到对掌子面的支撑作用。泥水分离设备用来在尽量减少膨润土的损失的条件下把膨润土悬浮液中的固体渣料分离出去。分离过的膨润土悬浮液通过泥水循环中的进泥管被重新泵回隧道掌子面。 The HSP is designed to effectively regenerate bentonite suspension used in tunnel excavation by means of conventional Hydroshield (Slurry Shield) or Herrenknecht Mixshield. With such tunnelling systems, bentonite suspension serves as a carrier fluid for both transport of excavated material from the tunnel face to the surface as well as for face support. The separation plant is used to remove solid material with a minimum loss of suspension. The regenerated suspension is pumped back to the tunnel face via the feed line of the slurry circuit. 分离过程可以分为初级筛分、粗颗粒渣料分离、细颗粒渣料分离和淤泥及粘土的分离四个阶段。 The process of separation can be broken down into primary screening, coarse particle separation, fine particle separation and silt and c
