| description | To provide an operation method of a dust collector capable of accurately switching the circulating speed of a screen corresponding to a dust amount.SOLUTION: An operation method of a dust collector driven by jointing a net frame having a dust collecting screen to an endless carrying chain and driving the chain via upper and lower sprocket wheels, includes the steps of: switching the rotation speed of the screen to a second speed higher than a first speed when a water level difference between an upstream side and a downstream side of the screen circulating at the first speed and capturing dust exceeds a set value, or when the water level difference does not exceed the set value and an upstream flow rate of the screen becomes lower than the set value; and switching the rotation speed of the screen to the first speed when the water level difference between the upstream side and the downstream side of the screen circulating at the second speed becomes lower than the set value, and the upstream flow rate of the screen exceeds the set value, and a dust amount to be caught by the screen becomes lower than the set value.SELECTED DRAWING: Figure 1
【課題】塵芥量に応じたスクリーンの周回速度の切り替えを精度良く実行できる除塵装置の運転方法を提供する。【解決手段】本発明の除塵装置の運転方法は、無端状のキャリングチェーンに塵芥捕集用スクリーンを備えた網枠を接合し、チェーンを上下部スプロケットホイールを介して駆動する除塵装置の運転方法において、第１速度で周回移動して塵芥を捕捉するスクリーンの上流側と下流側の水位差が設定値を超えたとき、又は水位差が所定値を越えずにスクリーンの上流側の流速が設定値を下回ったときにスクリーンの回転速度を第１速度よりも速い第２速度に切り替える工程と、第２速度で周回移動するスクリーンの上流側と下流側の水位差が設定値を下回ったとき、及びスクリーンの上流側の流速が設定値を超えたとき、及びスクリーンで捕捉する塵芥量が設定値を下回ったときにスクリーンの回転速度を第１速度に切り替える工程と、を有することを特徴としている。【選択図】 図１ |
