造纸废液碱回收治污系统的液-固旋流分离器

Liquid-solid vortex separators——Alkali recovery from paper-making wastewater in pollution control systems

用新型中小型液-固旋流分离器,使造纸黑液中的有机物、杂质、渣等固形物同碱液分离,较干净的稀碱液进入黑液蒸发器组,蒸发浓缩后回收烧碱。造纸绿液或白液和渣进入中小型新型液-固旋流分离器,快速连续运作,除去绿泥和白泥渣后成干净的澄清液,代替大型的缓慢速度重力沉降的绿液和白液澄清器、稀白液澄清器,废液经处理后达排放水标准。

After organisms,impurities,residues and other solids are separated from alkaline liquid in the alkali recovery from papermaking black liquid in pollution control systems, the mediumsmall sized liquidsolid vortex separators are used. As a result, the clean thin alkaline liquid goes into the black liquid evaporator system. After the black liquid is concentrated by evaporation,caustic soda is recovered. The green liquid and residues in papermaking go into liquidsolid vortex separator, working rapidly and continuously. After the green sludge and white sludge are removed and becomes clean and clarified liquid, in order to replace the original bigsized green liquid and white liquid clarifier which works slowly by gravity settling. The waste liquid pollution control has met the requirements of effluent discharge standard. They are highly efficient vortex separators for industrial water treatment.
