Dust mine ventilation

Introduction

Dust mine ventilation is composed by mine ventilator with a wet vibrating wire catching dust components. Dust-laden air is inhaled dust blower, after wet vibrating wire catching dust capture the dust, local dust purification, purification of air from the dust after catching dust exhaust outlet, to purify romantic purposes. The Dust Blower for mechanized excavation face, boring job in situ dust dusty air purification, can also be used to coal, rock roadway, shotcrete face drilling, blasting the workplace.

working condition

1、Environment temperature 0～40℃；

2、Altitude less than 1000 meters；

3、Relative humidity less or equal（95±3）％（25℃）；

4、Used in methane and coal dust explosive gas underground；

5、Atmospheric pressure：（80～110）KPa。

Advantages

Mine Wet Dust Ventilation has unique properties and characteristics. Manifested in the following aspects:

1, the principle of unique, small size, light weight, use a dust removal mechanism with a variety of "vibrating wire filter plate" means catching dust through the filtration velocity can be increased to 10-18m / s, and with the efficiency of catching dust was positively related characteristics, so that unit air volume occupied by a minimum of space, similar products only 10% to 40%.

2, the working low resistance, low energy consumption: working resistance 1200Pa, unit energy consumption of air volume about 30% of similar products.

3, dust, high efficiency, suitable for a wide range of dust concentration, measured when the dust concentration 24000mg/m3, can still work without clogging, low concentrations of dust and gas purification effect is equally satisfactory. Dust particle can capture a wide range of coarse dust and respirable dust catching dust has a high efficiency.

4, simple structure, no cleaning cycle, "vibrating wire filter plate" self-purification ability, long-term continuous operation, do not plug without removing the cleaning and maintenance, simple structure, easy to use.

Technical index

1, total dust collection efficiency: ≥ 97%;

2, respirable dust collection efficiency: (90 ~ 98)% (positive correlation with the filtration velocity characteristics);

3, the liquid-gas ratio: (0.02 ~ 0.09) L/m3 (air volume) (by air dust concentration level may be);

4, most of the dust blower fan static efficiency of not less than 55%;

5, the working resistance: 1200Pa (with rated working resistance shall not deviate more than 10%);

6, applies to spray water pressure: ≥ 0.3MPa;

7, for the environment temperature :0-40 ℃;

8, work: long-term continuous operation;

9, Working noise: ≤ 85dB (A);

10 Dust concentration range: (0 ~ 24000) mg/m3 (air volume);
