摘要:

为在矿山领域有效应用微纳米气泡水炮泥,以微纳米气泡水为研究对象,探究其作为水炮泥内部填充物质在降尘与消纳CO方面的关键性能。通过表面张力、接触角、喷雾降尘、溶液吸附等试验,考察微纳米气泡水润湿、氧化等基本特性及其对粉尘的降尘性能和CO的消纳效率。结果表明:微纳米气泡水比自来水的表面张力低,对煤接触角小,增强对煤颗粒的润湿性;随静置时间延长,坍塌的微米气泡提供大量·OH,提高微纳米气泡水催化氧化性能;微纳米气泡水比自来水降尘效率高,最高达到62.27%,且对呼吸性粉尘降尘作用效果更为明显;微纳米气泡水有效提高CO消纳效果,随微纳米气泡发生器循环时间延长、进气量增加以及洗气用水量升高,微纳米气泡水对CO消纳效率逐渐上升,但其增长率呈现先升高后降低的趋势;在最佳试验条件下,微纳米气泡水对CO消纳效率可达到64.27%。

Abstract:

To effectively apply micro-nano bubble water stemming in mining operations, this study investigated the key performance of micro-nano bubble water as the internal filling material in stemming for dust suppression and CO absorption. Experiments including surface tension measurement, contact angle analysis, spray dust suppression, and solution adsorption were conducted to examine the fundamental properties of micro-nano bubble water, such as wettability and oxidation capability, as well as its effectiveness in suppressing blasting dust and CO absorption efficiency. The results show that: compared with tap water, micro-nano bubble water exhibits lower surface tension and a smaller contact angle with coal, thereby enhancing the wettability of coal particles. With prolonged standing time, collapsed microbubbles generates abundant OH radicals, improving the catalytic oxidation performance of micro-nano bubble water. Micro-nano bubble water achieves higher dust suppression efficiency than tap water, reaching up to 62.27%, with a more pronounced effect on respirable dust. In addition, it significantly enhances CO absorption efficiency. As the circulation time of the micro-nano bubble generator increases, along with higher air intake and larger scrubbing water volume, the CO absorption efficiency gradually increases, though its growth rate first rises and then declines. Under optimal experimental conditions, the CO absorption efficiency of micro-nano bubble water reaches 64.27%.
