The CIP of the decanter is carried out in two steps: |
離心機(jī)的CIP清洗是在兩個(gè)步驟中進(jìn)行: |
First a High-speed CIP at full bowl speed, which is followed by a Low-speed CIP at speeds corresponding to just under 1*g (50 - 150 rpm). |
個(gè)高速CIP在滿轉(zhuǎn)鼓的速度,其次低速CIP在對(duì)應(yīng)于在1×g的速度(50 - 150 rpm)。 |
|
While the high-speed CIP is performed, the pipings, the inlet parts, and the outside of bowl and decanter casing are cleaned. The sludge remaining in the bowl after completion of the high-speed is cleaned out during the low-speed CIP. |
轉(zhuǎn)鼓,離心機(jī)的罩殼同時(shí)進(jìn)行高速CIP清洗,剩余污泥在轉(zhuǎn)鼓里由高速和低速清洗 |
|
When terminating the separation performance, the decantershould be prerinse with water until all visible solids and process material have been removed before using a liquid with cleaning detergent. |
離心機(jī)停止分離后,應(yīng)預(yù)用清洗水清洗直到所有可見(jiàn)的固體材料及工藝已在使用液體清潔劑去除。 |
|
In most cases water alone cannot remove the dirt and deposits, its removing power being insufficient. |
在通常情況下,憑借水的力量是不能去除所有沉積的污垢。 |
|
Chemicals such as sodium hydroxide, also known as caustic soda, must be added in order to achieve a satisfactory result. Caustic Solution: 1-1.5% NaOH, to ensure a pH value of 12 to 13. A detergent compound of NaOH with an admixture of complexing agent such as sodium-polyphosphates, EDTA, or should be used. |
為了達(dá)到滿意的清洗效果,必須添加化學(xué)試劑如氫氧化鈉,也稱為燒堿,其濃度為1-1.5 %,pH值12到13。NaOH洗滌劑化合物復(fù)合劑如EDTA,三聚磷酸鈉,。 |
|
An acid cleaning could be carried out as a supplement to thecaustic cleaning. Nitric acid (HNO), concentration 0.5%, is suitable. |
合適的酸洗可以代替堿洗。如濃度為0.5%硝酸(HNO)。
