摘　　要：以深井热湿环境下矿用空冷器气侧粉尘沉积行为为研究对象,建立热湿环境下矿用空冷器气侧粉尘沉积模拟实验平台,采用实验方法研究热湿环境下不同大小粉尘颗粒在空冷器气侧壁面的沉积行为.结果表明:热湿环境下,粉尘颗粒更容易在前列沉积,随着平均粒径的增大,壁面的污垢层越厚,且沉积形态呈泥状;气侧粉尘沉积质量与进风含尘平均初始粒径的大小呈正比,与相对湿度呈反比,且粒径小于40μm的颗粒更容易沉积.研究对于深井热湿环境下空冷器气侧的结垢产生机制以及采取合理的防、除垢措施,保障良好的矿井降温效果和安全生产具有理论指导意义.Taking the air-side dust deposition behavior of mining air cooler under hot and humid environment of deep wells as the research object,the simulation experiment platform of air-side dust deposition of mining air cooler under hot and humid environment is established.Then,the deposition behavior of different sizes of dust particles on the air-side wall of air cooler under hot and humid environment is studied by experimental method.Results show that the dust particles are more easily deposited in the foreground under hot and humid environment,and with the increase of the average particle size,the fouling layer on the wall surface is thicker and the deposition pattern is mudlike.The dust deposition quality on the air-side is positively proportional to the size of the average initial particle size of the inlet air containing dust and inversely proportional to the relative humidity,and the particles with particle size less than 40μm are more easily deposited.This study has theoretical guidance for the mechanism of fouling generation on the air-side of air cooler under the hot and humid environment of deep wells and the adoption of reasonable antiscaling and descaling measures to ensure the good mine cooling effect and safe production.
