PURPOSE:To improve cleaning efficiency by connecting the gap between the adjacent filter elements to a cleaning fluid outlet passage which is opened when the element is cleaned. CONSTITUTION:Plural or plural sets of filter elements 1 are provided in a fluid passage in series. The gap between the adjacent filter elements 1 or sets of filter elements 1 is connected to a cleaning fluid outlet passage which is opened when the element is cleaned. Namely, when the element 1 is cleaned, the inflow of the fluid contg. particulates to a tubular body 7 from a pipeline 8 is stopped, a valve 16 is closed, and cleaning water is introduced into the tubular body 7 from a pipeline 21. The cleaning water is passed through the elements 1 in a case shell 3, through holes and grooves of plates 2, holes 171 and 172 of the case shell 3 and a case head 4 from the hole 10 in the bottom 5 of a canister and then introduced into a pipeline 20. Consequently, cleaning efficiency is improved. |
