Abstract
PURPOSE: To maintain the power plant stably, at high efficiency and at a low operation cost by a mechanism wherein the filter treatment of a large amount of a circulating water system with high flow speed is carried at a high removing efficiency by constituting a filter layer by filling corrosion resistant metal spheres having the diameter of 1W3mm.
CONSTITUTION: A filter tank is formed from the corrosion resistant metal spheres having the diameter of 1W3mm comprising a material which is not corroded by contacting the same with the high temperature and a high pressure condensed water such as stainless steel or the like by filling the said spheres with uniform diameter or the mixture of the said spheres with different diameter. The operation of the filter device is carried out by passing the circulated water downwardly through the filter layer to filter and the backwash is carried out by the upflow stream. That is, the circulated water is supplied from a raw water tank 3 and filtered by the filter layer 2 to obtain a treated water from a treated water pipe 5. When the filter layer is crogged by the filter continuation, the backwash water is supplied to the filter layer 2 from the backwash water pipe 6 to develope and backwash the said filter layer, thereafter the exhauste water is discharged from a backwash water exhauste pipe 4.
