芯式过滤器

Core filter

【基本说明】：

芯式过滤器（也称作保安过滤器）大都采用不锈钢做外壳，内部装过滤滤芯（例如PP棉），主要用在多介质预处理过滤之后，反渗透、超滤等膜过滤设备之前。用来滤除经多介质过滤后的细小物质（例如微小的石英沙，活性炭颗粒等），以确保水质过滤精度及保护膜过滤元件不受大颗粒物质的损坏。

采用PP棉、尼龙、熔喷等不同材质作滤芯，去除水中的微小悬浮物，细菌及其它杂质等，使原水水质达到进水要求。

Basic Specificion:

Core filters, also known as security filters, are mostly adopting stainless steel as shell, with filter elements such as PP cotton inside. They are mainly used after multi-media pretreatment, before membrane filtration equipment such as reverse osmosis and ultrafiltration. It is applied to filter fine substances such as tiny quartz sand, activated carbon particles after multi-media filtration to ensure the filtration accuracy of water quality and protect membrane filter elements from damage by large particles.

PP cotton, nylon, melt blown and other different materials are used as filter elements to remove micro-suspended substances, bacteria and other impurities in water, so as to make the raw water quality meet the requirements of inlet water.

【结构及工作原理】：

    芯式过滤器主要由：滤布、滤网、滤片、烧结滤管、线绕滤芯、熔喷滤芯等构成。因滤材的不同，过滤孔径也不相同。

    芯式过滤器是介于砂滤(粗滤)与超滤之间的一种过滤，过滤孔径一般在0.5～120μm范围。同种形式的滤材，按外型尺寸可分为不同的规格。线绕滤芯(又称蜂房滤芯)有两种：一种是聚丙烯纤维---聚丙烯骨架滤芯，zui高使用温度60℃;另一种是脱脂棉纤维---不锈钢骨架滤芯，zui高使用温度120℃。 熔喷滤芯是以聚丙烯为原料，采用熔喷工艺形成的滤材，zui高工作温度60℃。 精密过滤可去除水中的悬浮物、某些胶体物质和小颗粒物。

    芯式过滤器利用滤芯的孔隙进行机械过滤。水中残存的微量悬浮颗粒、胶体、微生物等，被截留或吸附在滤芯表面和孔隙中。随着制水时间的增长，滤芯因截留物的污染，其运行阻力逐渐上升，当运行至进出口水压差达0.1MPa时，应更换滤芯。保安过滤器的主要优点是效率高、阻力小、便于更换。

Structure and working principle:

The core filter mainly consists of filter cloth, filter mesh, filter, sintered filter tube, wire wound filter element, melt blown filter element, etc. Because of the different filter materials, the filter aperture varies with the filtration material.

Core filter is a kind of filter between sand filtration (coarse filtration) and ultrafiltration, and its pore size is generally in the range of 0.5-120 micron. The same type of filter material can be divided into different specifications according to its size. Wire-wound filter element, also known as beehive filter element, has two kinds: one is polypropylene fiber - Polypropylene skeleton filter element of which the highest using temperature is 60 degrees C; the other one is degreased cotton fiber - stainless steel skeleton filter element of which the highest using temperature is 120 degrees C. Melt-blown filter element is a kind of filter material which is made of polypropylene by melt-blown process. The highest working temperature is 60 C. Precision filtration can remove suspended solids, some colloidal substances and small particles in water.

The core filter uses the pore of the filter element for mechanical filtration. The remaining suspended particles, colloids and microorganisms in water are intercepted or adsorbed in the surface and pore of the filter core. Because of the deposits contamination, the resistance of filter element increases gradually with the increasing of water-making time. When the pressure difference between inlet and outlet reaches 0.1 MPa, the filter element should be replaced. The main advantages of security filter are high efficiency, low resistance and easy to replace.
