Description

격자형 심지를 포함한 섬유지지체 중공사분리막 {Fiber supported hollow fiber membrane contained wick of cross stripes}Fiber supported hollow fiber membrane contained wick of cross stripes}

본 발명은 폐수에 함유된 부유성 입자를 펌프 등의 물리적인 힘에 의해 가압 및 흡입 여과 할 수 있는 격자형 심지를 포함한 섬유지지체 중공사분리막에 대한 기술이다.The present invention relates to a fiber support hollow fiber separator comprising a lattice wick capable of pressurizing and suction filtration of suspended particles contained in waste water by a physical force such as a pump.

보다 자세하게는 폐수 중에 존재하는 입자성 물질을 제거하는 격자형 심지를 포함한 섬유지지체 중공사분리막으로 중공사분리막의 내부에 공간을 일정하게 분할하며 구조적 형태를 일정하게 유지시켜주는 격자를 포함한 섬유지지체와 섬유지지체 외부 표면에 고분자 수지를 코팅 또는 도포하여 제조된 중공사분리막으로 코팅 또는 도포된 고분자 수지의 정밀여과 분획 특성으로 입자성 물질을 차단하고 여과액만을 투과 후 여과 액은 섬유지지체를 통과하는 격자형 심지를 포함한 섬유 지지체 중공사분리막이다. 중공사분리막은 내부의 격자로 인하여 형성되며 일정하게 분할된 유로를 통하여 여과액이 이송되어지는 격자형 심지를 포함한 섬유지지체중공사분리막이다.More specifically, the fiber support hollow fiber membrane including a lattice wick to remove particulate matter present in the wastewater, and the fiber support including a lattice that divides the space uniformly in the hollow fiber membrane and maintains a constant structural form. A hollow fiber membrane prepared by coating or applying a polymer resin on the outer surface of the fiber support to block the particulate matter with the fine filtration fraction characteristics of the polymer resin coated or coated, and then pass through the filtrate only, and the filtrate passes through the fiber support. It is a fiber support hollow fiber separation membrane including a mold wick. Hollow fiber separation membrane is a fiber-supported hollow fiber membrane, including a lattice wick which is formed due to the internal lattice and the filtrate is transported through a regularly divided flow path.

일반적으로 중공사분리막은 고분자 수지의 단독으로 제조되어 중공사분리막 내부의 단일 유로를 갖고 있어 가압 또는 흡입 등의 방법으로 액체의 여과과정이 장기간 지속되거나 중공사분리막의 표면이 오염되면 투과 압력의 상승으로 구형의 중공사분리막의 형태는 타원형으로 수축하여 결과적으로 중공사분리막 내부 유로가 좁아지게되어 여과액의 원할한 이송이 어렵게 되고, 또한 중공사분리막의 구조적 결함을 주게되어 그 수명이 짧아 지게된다.In general, hollow fiber membranes are made of polymer resin alone and have a single flow path inside the hollow fiber membranes. Therefore, if the filtration process of the liquid continues for a long time or the surface of the hollow fiber membranes is contaminated by pressure or suction, the permeation pressure is increased. As a result, the spherical hollow fiber membrane is shrunk to an elliptical shape, consequently narrowing the internal flow path of the hollow fiber membrane, making it difficult to smoothly transport the filtrate, and shortening the life of the hollow fiber membrane. .

또한, 종래의 중공사분리막은 침적법 및 연신법 등에 의하여 생산되어지며 그 내부 EH는 구조적으로 어떠한 심지 또는 섬유지지체를 갖고있지 않아 일반적으로 알려져 있기로 그 인장강도가 200 gf 이하로 수중의 협잡물 등의 혼입에 의한 분리막의 절단 및 파손 등 분리막의 성능 저하와 손상 등의 문제를 안고있다.In addition, the conventional hollow fiber membranes are produced by the immersion method and the stretching method, and the internal EH does not have any wick or fiber support in structure, so it is generally known that its tensile strength is 200 gf or less, There are problems such as degradation and damage of the membrane, such as cutting and breakage of the membrane due to mixing.

그러므로 본 발명은 상기의 문제점을 해결 방안으로 격자형 심지(1) 외부에 섬유지지체(2)를 직조한(도 2)후 그 섬유지지체(2) 외부 표면에 고분자 수지(5)를 코팅 및 도포하여 정밀여과 분획 특성을 갖는 중공사분리막(도 3)을 제공함으로서 가압 및 흡입에 의한 여과액의 장시간 투과시 중공사분리막(도 3)의 구조적 형태가 변형되지 않음은 물론, 본 발명의 중공사분리막(도 3) 내부로 원할한 여과액의 수송을 할 수 있는 내부유로(6)를 제공하며, 격자형 심지(1)를 포함한 섬유지지체 중공사분리막(도 3)은 격자형 심지(1)와 섬유지지체(2) 및 고분자수지(5)의 3중 구조로 구성됨을 특징으로 하는 중공사분리막(도 3)으로 그 인장강도가 65,000 gf로 수중의 협잡물 등의 혼입에 의한 분리막의 절단 및 파손 등 분리막의 성능 저하와 손상 등의 문제를 해결할 수 있다.Therefore, the present invention is to solve the above problems by woven fiber support (2) on the outside of the lattice wick (Fig. 2) and then coating and applying the polymer resin (5) on the outer surface of the fiber support (2) By providing a hollow fiber separation membrane (FIG. 3) having a fine filtration fraction characteristics, the structural form of the hollow fiber separation membrane (FIG. 3) during the long time permeation of the filtrate by pressure and suction, as well as the hollow fiber of the present invention An internal flow path 6 capable of transporting a smooth filtrate into the separation membrane (FIG. 3) is provided, and the fiber support hollow fiber separation membrane (FIG. 3) including the lattice wick 1 is a lattice wick 1 And the fiber support (2) and the polymer resin (5) in the structure of the hollow fiber membrane (Fig. 3) characterized in that the tensile strength of 65,000 gf of the membrane separation and breakage due to the mixing of impurities such as underwater Problems such as deterioration and damage of the separator can be solved.
