Cleaning Problem in Pulp and Paper Mill by High Pressure Jet Water

II. High Pressure Shower Pipe

Abstract

The idea of high pressure on shower pipes is not new but practical application does not yet.There fore, we examined a spraying test by Emerson Shower Pipe at Asahi Iron Works Co., in order to determine what effect the high pressure spray have on washing.
From this test, we found that the using of high pressure saves a consumption of fresh water as compared with the using of conventional low pressure.Thereto, it can be estimated that the washing effect of spray on high pressure is approximately proportional to the water speed (U²) and the quantity of the spray (Q), whereas a washing effect can be computed as (U²·Q).
