Description

A foam dust removal device

technical field

The utility model relates to the technical field of dust removal equipment, in particular to a foam dust removal device.

Background technique

Coal mines, metal and non-metal mines, open-pit mining, culvert mining of hydropower stations, tunnel excavation and other places need to be dedusted. The existing dust removal methods mainly include wet dust removal, ventilation dust removal, and dust isolation. In some cases, the dust removal efficiency is acceptable. However, for mining, especially underground mining, culvert construction and tunnel mining in the early stage of hydropower stations, the dust removal efficiency is low, which has a serious impact. Safe production and the physical and mental health of workers.

Although wet dust removal has obvious dust removal effect, it also has great limitations and uncertainties.
