FILTRATION DEVICE AND METHOD OF FILTERING HIGH-PRESSURE FLUID TO BE TREATED

摘要

PROBLEM TO BE SOLVED: To provide a filtration device which can use a filtration vessel for filtration of high-pressure fluid to be treated as it is even when the filtration vessel has not satisfactory pressure-resistant performance but has clean specification, and can facilitate replacement or maintenance of the filtration vessel, and to provide a filtration method using the filtration device.;SOLUTION: The filtration device 10 is provided with: a filter; and the filtration vessel 12 which allows the filter to be arranged therein and allows a first inflow line A and a discharge line C of high-pressure fluid to be treated to be connected thereto, wherein a pressure vessel 11 in which the filtration vessel 12 is arranged therein and to which a second inflow line B of high-pressure fluid is connected is further included, wherein the fluid to be treated is caused to flow through the filtration vessel 12 from the first inflow line A, and the high-pressure fluid is caused to flow into the pressure vessel 11 from a second inflow line B, so that the filtration vessel 12 is formed so as to permit pressurization from the outside.;COPYRIGHT: (C)2011,JPO&INPIT
