Plain-English summary
This study focuses on improving air quality in mines after blasting, which releases harmful pollutants. Researchers developed a purification system that uses tiny bubbles in water combined with a special carbon filter to clean the air quickly. They tested different settings and found that using a high-pressure nozzle and specific types of filters worked best. The results showed that this system could significantly reduce dust and harmful gases like carbon monoxide and hydrogen sulfide. Overall, the system was effective in reducing pollution in mining environments.
Abstract
In order to create a safe and healthy working environment in mines, an issue that urgently needs to be addressed is the rapid discharge of high concentrations of toxic and harmful pollutants after blasting. This paper proposes a deep well rapid purification system based on the combination of nanobubble water spray and water bath/wire mesh carbon, and conducts single-variable optimization tests on the parameters of micro-nano bubble water and the atomizing nozzle. The wet spray fiber grid and carbon adsorption network form in sequence and verify the purification experiment under the clear optimal parameters. The results show that the micro-nano bubble water is used as the spray medium, and a high-pressure nozzle with a diameter of 0.4 mm is also used. The water supply pressure of the nozzle is 3.0 MPa, the wet spray fiber grid uses a double-layer 10-mesh metal wire, and the carbon adsorption network uses 5 mm activated carbon fiber cotton as the optimal parameter for the deep well rapid purification system. Under these conditions, the efficiency of total dust and exhalation dust reduction is 72.90% and 79.17%, respectively, and the purification efficiency of CO, H<sub>2</sub>S, and SO<sub>2</sub> reaches 84.39%, 78.75%, and 55.54%, respectively. This study provides reference data for efficient pollution reduction in mines and has high practical value.
