Comprehensive Treatment Technology and Application of Scale in Coal Mine Pump Station
CHEN Cheng
Abstract：In response to the frequent scaling problem of gas extraction pump station equipment in Guanzhuanghe Coal Mine,scale and water samples were collected.Qualitative and quantitative analysis of scale and water samples were carried out using X-ray diffraction spectroscopy(XRD)and chemical substance content determination methods to determine the composition of scale substances and the content of circulating water and new makeup water elements in the pump station.A corresponding comprehensive treatment plan was formulated:after online cleaning with targeted cleaning solution,high entropy alloy scale inhibition devices were installed on the circulating water and new makeup water inlet pipelines for scale inhibition.Through on-site application results verification,it was found that the scale inside the equipment was thoroughly removed.After installing a scale inhibition device,the cleaning cycle was extended from 3 months to 1 year.This solution provides technical and equipment support for scale prevention and control.
