The utility model relates to an inner supporting hollow fiber membrane, which comprises a shell. One side of the shell is provided with a water inlet, the other side is provided with a dense water outlet, the top of the shell is provided with a water inlet, the bottom of the shell is provided with a water inlet cavity, the bottom of the water inlet cavity is connected with a stirring shaft, the outer side of the stirring shaft is connected with a stirring blade, and the upper part of the water inlet cavity is provided with a water inlet separator. A water inlet pipe is arranged on the water inlet separator, and an inclined baffle is arranged in the water inlet pipe. The top of the water inlet pipe is connected with an outlet pipe, and the top of the water outlet pipe is connected with a spiral elbow pipe. Under the action of an inclined baffle arranged in the water inlet pipe, the water flow of the utility model accelerates the flow speed, and when passing through the spiral elbow pipe, the water flow forms turbulent flow under the guidance of the spiral elbow pipe, thus reducing sedimentation. After the water flow out, the force on the rotating disc is upward, so that the rotating disc rotates, thus forming a circulating water flow, continuously impacting the bottom sediment, and further reducing the sediment.
【技术实现步骤摘要】
一种内支撑中空纤维膜
本技术涉及一种内支撑中空纤维膜,属于纤维膜
技术介绍
柱式中空纤维膜组件由于具有较高的装填密度和产水量,膜组件连接和装卸方便,是目前工业上应用最为广泛的膜组件形式。柱式中空纤维膜组件又分为内压式中空纤维膜组件和外压式中空纤维膜组件两种,内压式中空纤维膜组件是流体流经中空纤维膜的内腔,由于流动阻力较大,所以通常膜组件长度较短;而外压式中空纤维膜组件是流体流经中空纤维膜的外侧,一般来讲,在相同膜面积装填密度情况下,外压式中空纤维膜组件流道较宽,水流阻力相对较小,所以可以实现膜组件长度更长和膜面积装填密度更高,而且可以采用加气擦洗,提高清洗效果。但是现有的膜组件进水管管口竖直设置,进水布气呈层流状态,进水管管口与中空纤维膜丝之间易产生进水盲区,导致布水不均匀,影响膜丝的出水过滤性能,现有技术中虽然也有使水形成紊流,可减少沉淀的改进,但是效果并不太理想。
