Description
また前記濾布ベルトの送り速度は、０．５〜２ｍ／ｍｉｎであることが好ましい。実験によれば、この送り速度の範囲内であれば、上記二流体ノズルを使用することで、洗浄水量を削減することができた。
さらに前記二流体ノズルは、前記濾布ベルトの幅方向に向けて複数個設置され、各々の二流体ノズルから噴射される気液混合ミストが重ならないように該二流体ノズルの取り付け角度が調節されていることが好ましい。その理由は、一つの二流体ノズルから噴射される気液混合ミストと他の二流体ノズルから噴射される気液混合ミストが接触し、重なり合うと、気液混合ミストが重なった箇所でお互いの気液混合ミストの噴霧打力を打ち消し合い、その箇所での濾布ベルトの洗浄効果が得られにくいためである。
Moreover , it is preferable that the feed speed of the said filter cloth belt is 0.5-2 m / min. According to the experiment, it was possible to reduce the amount of washing water by using the two-fluid nozzle within the range of the feed rate.
Further, a plurality of the two-fluid nozzles are installed in the width direction of the filter cloth belt, and the mounting angle of the two-fluid nozzles is adjusted so that the gas-liquid mixing mist ejected from each two-fluid nozzle does not overlap. It is preferable. The reason is that if the gas-liquid mixing mist ejected from one two-fluid nozzle and the gas-liquid mixing mist ejected from another two-fluid nozzle come into contact with each other and overlap, the gas-liquid mixing mist overlaps each other at the location where the gas-liquid mixing mist overlaps. This is because the spraying force of the liquid mixed mist cancels each other, and it is difficult to obtain the cleaning effect of the filter cloth belt at that point.
