Detailed description of the invention
As shown in Figures 1 to 6, a kind of efficient wet-type dust removal fan for mine comprises the fire-proof motor 2 of blower housing 4, impeller 1 and drives impeller.Impeller adopts diagonal flow type impeller, and fire-proof motor is sealed in cage 3.The interlayer formed between cage and Blower Housing is air channel, arranges that several make to be produced by air-flow the helical form guide vane of eddy flow in interlayer.Dehydration tube 6 is relative with blower housing fixing, dehydration tube has the water-permeable passage 5 that some roads run through barrel.Arrange impeller, cage and dehydration tube in turn along in airflow direction blower housing, have gap between dehydration tube and blower housing, cleaning solution outlet is arranged at impeller air inlet port place.
The technology that the utility model utilizes the exploitation of conventional art theory new, set up new theory and manufacture new equipment, meeting working condition, is improve must needing of working environment.According to existing domestic and international technical know-how, use hydrodynamics, aerodynamics, gas-liquid mass transfer scheduling theory, in conjunction with working site condition and operating mode, develop the dedusting fan that a kind of volume is little, power is large, purification efficiency is high, stable, collect air force, collection and purification dust, gas-liquid mixed and be located away from one, make it adapt to airborne or work alone, can be used for underground coal mine and combine pick, coal mining interface, also can be used for colliery washed coal system.
The utility model is a kind of is medium with cleaning solution, under the effect of mechanical force, cleaning solution atomization is become fine droplets particle, is combined, reaches the object of purification by the shock of certain speed or the effect of emulsifier with powder dust particle.
The utility model is made up of parts such as impeller, fire-proof motor, dehydration tube, cleaning solution systems, utility model purification mechanism, equivalence or higher than Venturi scrubber, it forms blade by vane rotary with the high speed relative motion of air-flow, dusty gas to be mixed with cleaning solution, and there is a series of, complicated physical action in mixed process, the unwanted particles in air is combined with cleaning solution and reaches purification object.Enter dewatering part with air after cleaning solution completes mixing, washing effect, through gas-liquid separation, purified gas directly enters air simultaneously, and the cleaning solution after separation is collected.The utility model compact conformation, take up room little, lightweight, can Foundation Design be removed from according to field condition during installation, be convenient to Installation and Debugging.
Impeller blade 8 is diagonal flow type plate blade, and blade has the windward side of blade-like.The design of blade is proved by theory and practice, and airfoil type is also not exclusively suitable for fan blade, so it is designed to the blade of veneer band sword, makes blade drag very little.This programme adopts flat veneer to do blade, does that processing technology is simple, weight is little, saved electrokinetic energy like this.
Current collector is installed on impeller air inlet port, and current collector adopts cylinder and the combined current collector of circular cone.Current collector guides uniform stream to be full of impeller air inlet port with minimum drag losses.
Fire-proof motor be equipped with frequency converter, install frequency converter adjustment different conditions under load, energy consumption can be made significantly to reduce, the blast in performance parameter table, air quantity non-at full capacity time parameter, under the cooperation of frequency converter also have 30 ~ 40% the leeway of adjustment up and down.
Gas-liquid-solid mixture produces swirling motion by helical form guide vane, when by dehydration tube central passage, under the effect of gravity, centrifugal force and air pressure, realize gas-liquid separation, gas after separation is discharged from air outlet, and Fig. 6 shows air stream 9 and the liquid stream 10 at dehydration tube barrel place.Per pass water-permeable passage spiral extension on dehydration tube.Dehydration tube axis and impeller axis being parallel, on dehydration tube axis direction, the flow area of dehydration tube reduces from both ends to the middle gradually.
Catch basin is arranged at below dehydration tube, and cleaning solution recycles.Through gas-liquid separation, purified gas directly enters air, and the cleaning solution after separation enters catch basin, and after precipitation or filtration, cleaning solution is recycled again, and sludge slurry is regularly discharged.The valuable material recoverables such as the cleaning solution for purification medium recycles, coal slime sediment.
The fire-proof motor coordinated signals of cleaning solution supply pump and drives impeller.Effectively run to ensure that equipment is stable, the application life of extension device, must maintain cleaning solution during fan operation, therefore devise the fire-proof motor coordinated signals of cleaning solution supply pump and drives impeller, cleaning solution supply pump stops supply cleaning solution blower fan out of service.
