FQ3.55 Mine Pneumatic Axial Fan environmental pressures force significantly reduce the use of coal. FQ3.55 Mine Pneumatic Axial Fan power is China's largest coal consumer industry, accounting for more than 50% of the country's total coal consumption, but the sulfur dioxide emissions from coal combustion process, nitrogen oxides, smoke, dust and other FQ3. 55 Pneumatic roadway fan, is a major source of atmospheric pollutants. Most of the province is high-sulfur high ash coal mines, with the increase of environmental protection efforts, the use of coal will be gradually reduced. 1. Characteristics and uses FQ series of mine pneumatic fan jet type disturbance in the structure, there are two ends of the output shaft of the fan, the front mounted fan impeller, rear mount itself airflow from the fan-driven air distribution round, opened the cloth wind wheel incomplete ring outlet. When such a fan of work, even the impeller rotation, but also led to the cloth wind wheel rotation, produce a certain frequency within a cone, with a range of up to disturbance jet (8 ~ 15) m, which greatly enhances the surrounding gas volume Hybrid absorption capacity. The fan is suitable for underground mine ventilation exhaust blown dead, especially the upper corner area of ??accumulation of gas and harmful gases. FQ series compact pneumatic blower structure, small size, easy to install, safe, low noise, wide practicability.
