Filtration device

Abstract

Provided is a filtration device exhibiting a high water treatment capacity and capable of increasing the longevity of a hollow-fiber filter, in a water purification device not requiring a purification material and requiring a high water treatment capacity. The filtration device (3) has: a housing case (15) having a water inlet unit and a water outlet unit arranged on one end side thereof; and a membrane module (17) provided inside this housing case (15). A first flow path (31) for causing raw water that has flowed in from the water inlet unit (21) to flow further to the other end side of the housing case (15) than the membrane module (17), and a second flow path (33) for causing the raw water that has flowed further to the other end side of the housing case (15) along this first flow path (31) to pass through the membrane module (17) and flow to the water outlet unit (23) are provided inside the housing case (15). A spacer (19) is provided on the upstream side of the membrane module (17) in the second flow path (33).

Description

technical field [0001] The invention relates to a filter device for a cleaning device, in particular to a filter device used in a cleaning device for medical instruments such as endoscopes. Background technique [0002] Conventionally, the water purifier described in patent document 1 is known as a water purifier which filters raw water supplied from a water pipe, for example. The water purifier of Patent Document 1 is configured as follows: the raw water entering the filter element from one end side of the cylindrical water purifier element flows along the inner wall of the water purifier element toward the other end, and passes through the The activated carbon in the radial center on the other end side is then supplied to the outside as purified water through the hollow fiber membrane located on the one end side of the water purifier cartridge than the activated carbon. [0003] On the other hand, in Patent Document 2, there is a cleaning and disinfecting device for medic...

AI Technical Summary

Problems solved by technology

[0009] As such a filtering device for cleaning devices for medical instruments such as endoscopes that requires high water treatment capacity and does not require activated carbon, etc., if it is used, only the purification material is removed from the water purifier as described in Patent Document 1. In the final filter device, there is the following problem: although the amount of water treated per unit time is increased by removing the purification material, the longevity of the hollow fiber filter inside the filter device cannot be achieved.
