第五節 自動排渣分油機自動控制系統

一. 系統流程概要圖(CLEANING SYSTEM-SCHEMATIC

DIAGRAM)

DIRTY OIL 經過初步過濾，將污由中所含的固體雜質過濾出，再經加熱器適當加熱，經由OIL FEED PUMP 不間斷持續的注入SEPARATOR中，經由高速旋轉，清淨油、水、雜質因比重的不同而產生不同的離心力，清淨油被導引至日用櫃存放備用，水分及雜質則被排放至 Purifier Sludge Tank，排出的清淨油在被送至日用櫃前需先經過WATER TRANSDUCER檢測，若含水量超出設定標準，則警報響起，停止 DIRTY OIL繼續進油，若含水量合乎設定標準即輸送至日用櫃儲存備用。

二. 基本裝備 (BASIC CONCEPT)

每一淨油系統之組成，包含FOPX SEPERATOR、EPC-400 CONTROL UNIT、輔助控制系統和監視器. 如下圖為一單組淨油系統之佈置圖：

ALCAP CONCEPT

當SLUDGE在SLUDGE SPACE (H) 囤積至一定量、水進入DISC STACK (G)時，少量的水將隨著清淨油排出，降低淨油機的效能，裝於清淨油出口端之水分檢測器 MT4負責把關之責任，當監測到含水量超出標準值時，採取下列其一之方式排出：

a).經由WATER OUTLET VALVE V5 排出. b).經由SLUDGE PORT排出.

SLUDGE DISCHARGE FUNCTION

P孔為排泄SLUDGE、WATER用，P孔平時被SLIDING BOWL BOTTOM (Q)保持在關閉狀態，當OPENING WATER(15)進入時，排擠出CLOSING WATER，促使SLIDING BOWL BOTTOM向下開啟，P孔開啟並排放出SLUDGE、
