Pneumatic injection pressurization wet type foam generating device and using method thereof

The invention relates to a pneumatic injection pressurization wet type foam generating device and a using method thereof, belongs to the technical field of mine underground dust removal equipment, and solves the technical problems that existing wet type dust removal equipment is low in dust removal efficiency, weak in wind resistance, small in coverage area and poor in reliability. The foam solution is subjected to primary foaming in the primary foam generating device, and then is conveyed to the secondary foam generating device for secondary foaming. Through cooperation of the first-stage foam generating device and the second-stage foam generating device, compressed air is injected and pressurized through the second-stage foam generating device, generated high-speed airflow carries foam and can cover a dust source in all directions, and the foam generated by the device has the advantages of being high in dust removal efficiency, high in wind resistance, wide in coverage range and good in reliability. 一种气动引射增
