精密过滤器特点是什么?使用时应注意哪些问题?大连预处理系统-大力水处理设备-大连精密水处理系统

产品特点
1、过滤效率高:作液固过滤,小可过滤0.45um左右的颗粒,作气固过滤,小可过滤0.3um左右的颗粒,可滤除率99.9%,过滤压差低。
2、排干滤饼效率高:采用压缩气体快速反冲法可以很轻便的将附在微孔管外表面的滤饼快速地、有效地、安全的卸下。
3、再生效率高:采用简易的气液快速反冲反吹法可以将受到堵塞的微孔管进行高效且快速的再生,当滤管使用一段时间后,可采用化学方法再生,使滤管的使用寿命更长。
4、耐化学腐蚀的性能优越:微孔管耐各种酸、碱、盐和绝大部分有机溶剂,无毒、无味、无异物溶出,极适用于医药、食品、化工、环保等行业应用。
 
使用注意事项
◆不锈钢过滤器使用前必须检查配件和密封圈是否齐全,有无损坏,然后按要求把它装好。
 
◆新的过滤器必须用清洁剂清洗干净(请不要用酸类清洗)洗净后用高温蒸汽杀菌、消毒、洗净的过滤器要放好,避免污染。
 
◆新的滤芯是生产厂家在洁净的生产厂房内用塑料袋封装的未使用切勿撕破塑料包装,使用要求较高的滤芯,安装好后要经过高温蒸汽杀菌消毒。
 
◆安装滤芯时,两头平滤芯应先将滤芯下部固定插件装好,然后插入滤芯(折叠滤芯直接插入钢碗),插入时,滤芯一定要垂直,再将不锈钢压板扣住滤芯上部插件(折叠滤芯为翅片或三角箭头),旋紧拉杆螺丝不动即可。226接口的滤芯插件滤芯接口后,应旋转90度卡紧,这是安装中的关键,否则会影响密封程度,容易漏水,就达不到使用要求。
 
◆过滤器安装时进出水口不要接反,高的管口是进出水,低的管口是出水口,小的管口是排污口。
 
◆过滤的液体进入时,应打开过滤器上面的放气开关,让液体充满柱体,否则过滤效果不好。
 
◆筒体的压力表是液体压力显示表,如果是二级过滤,第一过滤器压力表指数稍少一些是正常现象,使用时间越长,压力会增大,流速减少,这说明滤芯空隙大多已被堵塞,要冲洗或者更换新的过滤芯。
 
◆在过滤时,使用的压力一般在0.1Mpa左右,能满足生产需要就可以了,随着时间与六流量的增加,滤芯微孔堵塞,压力增加,一般不要超过0.4Mpa,高绝对不能超过0.6Mpa。否则会损坏滤器滤芯或被击穿。
 
◆反冲洗滤芯,一定要用无菌水,否则会污染滤芯。反冲方法原出口变进口,把无菌水反方向打进去(要注意关闭原液过滤管道),打开排污口,操作人员看到滤液明显好转为宜。
 
◆生产完成不用时,尽量把滤液放光,停机时间不长,一般不要打开机器,滤芯不要拔掉,停机时间长或者滤液不宜隔夜存放,停机一定要清洗滤芯和滤器(也可以用反冲方法)
 
◆自选配套使用,要注意需要的流量、压力、泵的扬程要匹配,选型一般选用旋涡泵、输液泵等为宜,离心泵不适用。

Product features
1, filtration efficiency: make the liquid-solid filtering, minimum filter 0.45 um around the particle filter, air and solid, the smallest of filtering particle, um 0.3 can filter out rate, low differential pressure filtration 99.9 percent.
2 and drained filter cake of high efficiency: using compressed air recoil method can very quickly in the light will microporous filter cake outer surface of tube rapid, effective, safe.
3 and regenerative efficiency high: the simple gas-liquid fast recoil blow method can be blocked by the microporous efficiently and quickly regeneration, when the filter tubes used after period of time, can use chemical method to the use of the filter tubes lifespan.
4 and corrosion-resistant properties superior: microporous pipe resistance of acid, alkali, salt and most organic solvents, non-toxic, tasteless, no foreign dissolving, very suitable for medicine, food, chemical, environmental protection, etc.

Cautions
1 stainless steel strainer before use must check whether the sealing parts and complete, whether have damage, then according to the request it properly.

2 new filter must use cleaner clean (please don't use acid cleaning) with high temperature steam wash after sterilization, disinfection, clean strainer should put to avoid contamination.

Three new filter is manufacturer in the clean room of plastic packaging manufacturer use do not tear plastic packaging, use the filter to install, high-temperature sterilization of steam.

4 when installation, two flat filtering cores should be lower filter plugins pack good, then fixed inserting filter (folded filter directly into steel bowl), insert, filter must be stainless steel plate, vertical buckle folding filter plugins (upper filter for fin or triangle arrow), tighten the screws motionless tension. 226 the filter plugins filter interface should interface rotates 90 degrees, it is installed card, otherwise, it will affect the critical sealing, easy to use, not leak.

5 when install filters out, don't answer the pipe is high and low water, the orifice is an outlet, the smallest pipe is directly.

6 the filtration liquid into, should open a strainer above deflated switch, let the fluid filled with cylinder, or filtering effect is bad.

7. The cylinder pressure gauges are liquid, if that is secondary filter, the first filter pressure gauge less index is normal phenomenon, use longer, can increase the pressure and flow velocity, reduce the gap has been blocked filter, mostly to wash or replacement of the filtering.

8 when used in filter, the pressure on 0.1 Mpa, generally can meet the requirements of production, as time increases with six traffic jams, microporous filter, commonly pressure increases, the highest do not exceed 0.4 Mpa, absolutely cannot exceed 0.6 Mpa. Otherwise it will damage filter cores or breakdown.

9 flush filter, must use sterile water, otherwise will pollution filter. Methods the original import export recoil, change direction in sterile water filtration close attention to filter (pipe), open, operator saw filtrate sewage improved obviously.

The production is completed, as far as possible the filtrate was not long, general downtime don't open machines, filter, don't stop time deposit, or unfavorable overnight stop filtrate cores and filter must be cleaned (can also use recoil method),

11. Customize supporting the use, must pay attention to the flow rate, pressure and pump head to match, the selection is generally selected vortex pumps, infusion pump etc advisable, centrifugal pump does not apply.
