摘要
浓密机是湿法炼锌企业浸出车间液固分离的主要设备,使用寿命在30～50年左右。本厂浓密机底流输送系统流量控制阀消耗严重,占车间总成本的1/3,年累计达100余万元。采用变频技术对该系统进行控制,取得了较好的效果,有效地降低了成本。
The thickener is the main equipment for liquid and solid separation in leaching workshop of zinc hydrometallurgical enterprise,and its range of service life is between 30 and 50 years.The consumption of flow control valve in delivery system of thickener underflow is very serious,accounts for one third of total cost of flow control valve in workshop,the accumulative total of which reaches more than 1000 000 Yuan per year.The good effects were achieved and the cost reduced effectively through use of frequency conversion technology to control the system.
