作用原理:

       不銹鋼藍(lán)式過濾器是用過濾介質(zhì)把容器分隔為上、下腔即構(gòu)成簡單的過濾器。懸浮液加入上腔，在壓力作用下通過過濾介質(zhì)進(jìn)入下腔成為濾液，固體顆粒被截留在過濾介質(zhì)表面形成濾渣(或稱濾餅)。過濾過程中過濾介質(zhì)表面積存的濾渣層逐漸加厚，液體通過濾渣層的阻力隨之增高，過濾速度減小。當(dāng)濾室充滿濾渣或過濾速度太小時，停止過濾，清除濾渣，使過濾介質(zhì)再生，以完成一次過濾循環(huán)。
懸浮液過濾有濾渣層過濾、深層過濾和篩濾 3種方式。
①濾渣層過濾：過濾初期過濾介質(zhì)只能截留大的固體顆粒，小顆粒隨濾液穿過過濾介質(zhì)。在形成初始濾渣層后，濾渣層對過濾起主要作用，這時大、小顆粒均被截留，例如板框壓濾機(jī)的過濾。
②深層過濾：過濾介質(zhì)較厚，懸浮液中含固體顆粒較少，且顆粒小于過濾介質(zhì)的孔道。過濾時，顆粒進(jìn)入后被吸附在孔道內(nèi)，例如多孔塑料管過濾器、砂濾器的過濾。
③篩濾：過濾截留的固體顆粒都大于過濾介質(zhì)的孔隙，過濾介質(zhì)內(nèi)部不吸附固體顆粒，例如轉(zhuǎn)筒式過濾篩濾去污水中的粗粒雜質(zhì)。在實際的過濾過程中，三種方式常常是同時或相繼出現(xiàn)。

How it works:

       The stainless steel blue filter is a simple filter that separates the container into upper and lower chambers with filter media. The suspension is added to the upper chamber, and enters the lower chamber through the filter medium under pressure to become filtrate, and the solid particles are trapped on the surface of the filter medium to form a filter residue (or filter cake). During the filtration process, the filter residue layer existing on the surface of the filter medium gradually thickens, the resistance of the liquid passing through the filter residue layer increases, and the filtration speed decreases. When the filter chamber is full of filter residues or the filtration speed is too low, the filtration is stopped, the filter residues are removed, and the filter medium is regenerated to complete a filtration cycle.

There are three ways to filter the suspension: filter residue layer filtration, depth filtration and sieve filtration.

①Filter residue layer filtration: In the initial stage of filtration, the filter medium can only retain large solid particles, and the small particles pass through the filter medium with the filtrate. After the initial filter residue layer is formed, the filter residue layer plays a major role in filtration. At this time, both large and small particles are trapped, such as the filtration of plate and frame filter presses.

②Deep filtration: The filter medium is thicker, and the suspension contains less solid particles, and the particles are smaller than the pores of the filter medium. During filtration, the particles are adsorbed in the pores after entering, such as the filtration of porous plastic tube filters and sand filters.

③Screening: The solid particles retained by filtration are larger than the pores of the filter medium, and the solid particles are not adsorbed inside the filter medium, such as the rotary drum filter screen to filter out coarse impurities in the sewage. In the actual filtering process, the three ways often appear simultaneously or sequentially.
