Problems solved by technology

Therefore, in the existing hollow fiber membrane module, the filtration efficiency is high on the outer peripheral side, but the filtration efficiency decreases toward the center, which limits the filtration efficiency as a whole.

Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Fig. 1 shows a filter device 1 in an embodiment of the present invention. The axial direction of the filter cartridge 2 of the filter device 1 is installed (mounted, arranged) along the vertical direction. A funnel 3 is disposed inside the filter cartridge 2 , and the inner space of the filter cartridge 2 is divided into an upper filter chamber 4 and a lower filter chamber 5 by using the funnel member 3 . The funnel member 3 is a conical surface whose opening area becomes narrower downwards, and a lower end opening 3a is formed at the lower end. The filter chamber 4 and the recovery chamber 5 are communicated through the lower end opening 3a.

[0019] In the filter chamber 4, the hollow fiber membrane module 6 is arranged in a state extending in the vertical direction. In this hollow fiber membrane module 6, the upper side of a plurality (hundr...

Abstract

A filter device of a hollow fiber membrane type is prevented from being clogged. A filter cylinder is two-divided with a filter chamber on the upper side and a recovery chamber on the lower side by a funnel member. A hollow fiber membrane module is arranged in a state spread in a broom form within the filter chamber. Raw fluid is radially ejected through ejection ports of an injection pipe. Consequently, the hollow fiber membrane module positively spreads into a broom form while vibrating. Due to this, raw fluid sufficiently reaches an inside of the hollow fiber membrane module, thereby achieving efficient filtration and stripping away of deposit. The stripped deposit enters the recovery chamber. The deposit entered the recovery chamber does not return to the filter chamber. Thus, there is no re-deposition of the once-removed deposit onto the hollow fiber membrane module.

Description

technical field [0001] The present invention relates to a filter device. In a filter device using a hollow fiber membrane module and using an external pressure filtration method, the attachments attached to the surface of the hollow fiber membrane module can be effectively removed and at the same time, the removed attachments can be prevented from reattaching to it. , so as to better improve the filtration efficiency. Background technique [0002] Hollow fiber membranes are known as liquid filter media. By filtering with such a hollow fiber membrane, it is possible to produce ultra-pure water, sterilize upper water, refine solvents or lubricating oils, recover effective substances in solvents, and treat or recover waste liquids and waste water. [0003] As a method of filtering using a hollow fiber membrane, there are an external pressure filtration method and an internal pressure filtration method. In a filtration device using a hollow fiber m...
