Black pressure filter
纸原料经碱法蒸煮后，必须将浆料中的黑液提取出来供碱回收之用，但不论使用何种黑液提取设备，其黑液中均或多或少带有纤维或各种残渣。（尤其是当提取设备的过滤网破裂，管道或阀门损坏等情况发生时，可能使黑液含有更多的纤维），至使在黑液进行蒸发浓缩时，这些纤维往往会在蒸发器的管（板）壁沉积，使加热管（板）结垢，影响蒸发效率，因此，在黑液送往碱回收车间之前，应该首先通过黑液过滤设备除去纤维，要求黑液含纤维量降低到60mg/L以下，以适应蒸发部的要求。
本机是现代国际上过滤制浆黑液先进的新型设备，是在吸收近期引进的新技术的基础上研制开发的新一代黑液过滤设备。采用高速旋筒和微孔过滤筛鼓（直径只有0.1-0.3mm）等新结构。在压力状态下工作，比目前国内采用传统的圆网式黑液过滤机有：过滤能力大，滤液清净度高，技术装备水平高等优点。
适用于过滤制浆造纸厂的蒸煮黑液，也可作为过滤其他废液，废水的环保设备。
用途:
●过滤碱法制黑液或酸法制浆红液，去除细小纤维。
●过滤纸机白水，回收纤维，循环用水。
●净化纸厂中段废水，减轻废水处理系统负荷。
●过滤纸厂循环用水，去除阿质，提高水质。
特征:
●滤液的清净度高。
●在压力状态下进行过滤，通过能力大。
●滤孔不堵塞，运行可靠，操作方便。
●采用不锈钢材料制造，防腐性能好。
●密闭操作，不会产生泡味。
●设备体积小，安装方便。
Black filter paper as raw material alkali cooking, the slurry must be in the black liquor extracted for recovery purposes, but no matter what the use of black liquor extraction equipment in both the black liquor with more or less fiber Or a variety of residues. (Especially when extraction equipment breakdown of the filters, valves or damage to the pipeline, such as happens when black liquor may contain more fiber), to make the black liquor evaporation carried out, these fibers are often in the evaporator Pipe (board) wall deposition, so that the heat pipe (plate) scale, the impact on the efficiency of evaporation, in the black liquor recovery sent prior to the workshop should be the first black liquor through the filtration equipment to remove fibers, with black demands to reduce the amount of fiber 60mg / L of the following, in order to meet the requirements of the Department of evaporation.
Local modern international pulp black liquor filter of a new type of advanced equipment in the near future to absorb the introduction of new technologies on the basis of research and development of a new generation of black liquid filtration equipment. Using high-speed rotating cylinder and the porous filter drum sieve (diameter of only 0.1-0.3mm) and other new structures. To work under pressure in the state than the current traditional black rotary-filter: the ability to filter, clean filtrate high, high level of technical equipment.
Filter applied to the pulp and paper mill black liquor cooking, and other filters can be used as waste, waste water environmental protection equipment.
Uses:
● filter acid or alkali legal black liquor pulping red liquid, remove the tiny fibers.
● White filter paper machine, fiber recycling, and reuse.
● paper mill in the middle of wastewater purification, wastewater treatment systems to reduce the load.
● filter paper circulating water to remove Arab-quality and improve water quality.
Characteristics:
● a high degree of purity of the filtrate.
● under pressure to filter through large capacity.
● filter does not plug the hole, reliable, easy to use.
● use of stainless steel materials, good anti-corrosion properties.
● operate in confined and will not have a bubble flavor.
● devices are small, easy to install.
