K40 mine energy-saving ventilation

Introduction

The ventilators specifically based metallurgy, nonferrous metals, gold, chemicals, building materials and other types of non-coal mines nuclear industry needs and design, can be used as the main fan and auxiliary fan can be installed on the surface, can also be installed in the underground, suitable for multi-joint operation fan.chinacoal05

Characteristic

1, using twisted airfoil blades, pneumatic, high efficiency, energy-saving effect is extremely significant.

2, the performance and specifications complete, resistance to air flow with various types of ventilation network good match, you can maintain long-term efficient operation.

3, has a steady flow loop device characteristic curve no hump, no surge danger at any resistance state are safe and stable operation, and is suitable for multi-turbine combined operation.

4, the use of the motor and impeller directly linked structure, the overall stable, easy installation, easy maintenance, low resistance device Bureau.

5, compact structure, good moisture resistance. Fans main use of steel, structural steel welding, material for the steel blade, hollow, blade and machine high strength, anti-mine blast shockwave ability, can be mounted on the surface, also suitable for installation in underground, particularly suitable as a multi-level machine station ventilation system stations fan.

6, can reverse the anti-air, anti-air ratio greater than 60%, no anti-duct construction.

7, the blade angle adjustable, according to changes in mine production, at any time adjust the fan status.

8, civil works is very small, you can save a lot of investments.

9, the noise is low.

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
