为了探究传统小型矿用空冷器在降温的同时是否具备除湿能力的问题,采用试验研究和数值模拟相结合的研究方法,构建了小型矿用空冷器除湿试验装置及其相应模型。在试验研究中对小型矿用空冷器输送的冷风温度和湿度进行4种不同工况设置,即20℃、35%,20℃、55%,25℃、35%和25℃、55%。保持其他试验参数固定不变,监测环境相对湿度在不同试验条件下的变化情况,然后采用ANSYS数值模拟方法对以上4种不同工况进行模拟研究,并对试验结果加以验证。结果表明:小型矿用空冷器在降温的过程中具有一定的除湿能力,但整体除湿效果并不明显,需要进一步探究除湿能力较强的矿用降温除湿空冷器设备,以增加高温高湿矿井的安全生产效率。

ln order to studly and disoover the conventional small ype mine air cooler would have the de- moisture capacity while the air cooler would have the temperature reduction,a study method combined with the experiment study and the numerical simulaton was applea io estaDlSnthe de-moisture experiment device and other related model of the small type mine air cooler.During the experiment study,there were four diferent devices conducted to send the cool air temperature and humidity to the small ype mine air coole,the cool temperature and humidity were 20 ℃and 35%,20 ℃ and 55%,25 ℃ and 35% and 25 ℃ and 55% individual . Other experiment parameters were kept stable and no change and the variation conditon of the environment relative humidity under the diferent experiment condition was montored and measured.Then the ANSYS numerical simulation method was applied to the simulation study on the four different devices and the experiment results were verified.The resultsshowed that during the cooling process,the small type mine air cooler would have a certain de-moisture capacity,but the completed de- moisture effect was not obvious and a further discovery and study should be conducted on the mine cooling and de-moisture air cooler equipment with a higher de-moisture capacity in order to improve the safety production efficiency of the high temperature and high moisture mine.
