Abstract
Description
technical field
[0001] The invention relates to a smoke and dust purification system. Background technique
[0002] During the blasting operation, a large amount of dust and harmful gas will be produced. The dust is mainly free silica, especially the dust concentration in drilling, blasting, and slugging processes is higher. Harmful gases mainly include CO, CO 2 γH 2 , NO, HCN, CH 4 , NH 3 , SO 2 , NO 2 γH 2 S. The blasting construction of underground workshops belongs to confined space blasting. The dust and harmful gases generated will accumulate on the working surface for a long time and are not easy to disperse, causing great harm to the health of workers. The current conventional treatment method is to rely on tunnel ventilation. The dust and harmful gas on the face of the tunnel are discharged, but the dust will pollute the entire tunnel during the discharge process, endangering all operators who enter the tunnel, and the cost of electricity is high. Therefore,...
