The present invention is characterized in that an annular rack of the dust removing device is provided with an anode dust removing brush, a cathode dust removing brush and an anode dust removing shovel, and dust on the anode and the cathode can be removed in the operating state; a corona discharge pole is formed in the dust hopper and is capable of suppressing secondary blowing dust. The present invention has the advantages of high dust concentration at an inlet, great air flow treatment, convenient and reliable dust cleaning, compact structure, low cost, convenient maintenance, small occupation area, moisture condensation resistance and high dust collecting efficiency.
Description
The present invention relates to environment protection equipment; promptly be to utilize machinery, electrostatic precipitation mechanism and the resistive connection that designs reveals multimachine reason deduster, it mainly is made of sleeve pipe, ash bucket, corona wire, electric heating element, deashing device and the high voltage power supply that standpipe, bottom have a reverse taper.
At present, the kind of deduster is a lot, but all has certain problem.As cyclone dust collectors are the centrifugal force that utilizes swirling eddy to produce is separated dust from gas devices.Be generally used for the grit of particle separation diameter greater than 10 μ m, general efficient is about 85%.For the superfine dirt that floats is helpless.Because in tornadotron, the motion of solid particle is a continuous turbulent flow admixture, when the turbulent flow eddy flow reverses in cone space forms, the dust of having separated, the swirling eddy that might be made progress is taken away from escape pipe.Simultaneously, the dust of having separated in the ash bucket might be taken away from ash bucket once more by the secondary gas flow in the boundary layer, so its normal and other duster parallels use.Electrostatic precipitator is by the sparking electrode that produces corona current and form the solid particle of negative electrical charge or the collector electrode of flue dust is formed.Rely on dc high voltage electric field to capture the dust that is suspended in air-flow.It is a kind of cleaner preferably.Can isolate the grit that particle diameter is 0-10 μ m, efficiency of dust collection depends primarily on the flow velocity of gas, the factors such as intensity, electrode situation and dust performance of electric field, and efficiency of dust collection can reach more than 99%.But, can make dust charged insufficient because gas flow rate is too fast in the electrostatic precipitator.The dust content height can make the hurried decline of corona current, also may level off to zero when serious.These phenomenons all will influence efficiency of dust collection.Therefore, people are seeking the more rational cleaner of structure.The notification number that China's patent is announced is the cyclone electrostatic deduster of CH2119964 and the repeatedly rotation electrostatic precipitator that notification number is CH2097689, and than simple cyclone dust collectors or electrostatic precipitator, performance has had very big improvement, and efficient improves greatly.It is big that but these two kinds of dedusters all exist volume, complex structure, maintenance difficult, the easy dewfall of under the big state of gas humidity, working, vibration dust-cleaning mechanism is at the top, rapping power is little, and the dust difficult drop-off influences the dust migration velocity and is easy to generate prickle hypertrophy and the creepage electrical breakdown accident that causes of insulator dust stratification; Rapping power is strong, easily produces the broken and corona wire broken string of insulator.
Purpose of the present invention is to overcome above all weak points, and provides a kind of inlet dust concentration big, and it is big to handle air quantity, and field gas velocity is fast, and deashing is convenient and reliable, efficiency of dust collection height, the efficient dust collector of the multimachine reason that resistive connection reveals.
The present invention adopts following scheme to solve.It mainly is made up of a standpipe and sleeve pipe, ash bucket, corona wire, dust-blocking cover, electric heating element, ash bucket discharging electrode, deashing device, air valve, high voltage power supply of being enclosed within outside it.It is characterized in that:
Corona wire adopts stainless steel tube or coating steel pipe to make, and is welded with n row prickle around it, and there is one grade of dust hood on top near the insulator place, and there is the ash bucket discharging electrode that stops Returning flow to roll the effect of dust again the lower end.Ash bucket discharging electrode is a bullet, and prickle is arranged at the bottom.
Deashing device is by ring stand, and the anode deashing shovels, anode deashing brush, cathode ash-clearing brush, pulley, steel wire rope, reel, stepless speed-regulating motor, decelerator, lead, v shape guide plate, limit switch, compositions such as high voltage insulator.Anode deashing brush is installed on the ring stand of deashing device, the cathode ash-clearing brush, anode deashing shovels etc. have high voltage insulator to isolate between cathode ash-clearing brush and the ring stand, make the deashing device can be under the dust-precipitator duty, opposition inside pipe wall and corona wire and on the prickle deashing.Ring stand is lifted in the standpipe with steel wire rope, and with the tightening up and loosen and rise in standpipe or descend of steel wire rope, the speed that ring stand rises in standpipe or descends is controlled by stepless speed-regulating motor.
Have two ring stand leads in the standpipe at least, keep ring stand normally operation up and down in standpipe, and very big the issuing tiltedly of unlikely generation,, the phenomenon of the short circuit that ring stand contacts with corona wire can not take place yet even under steel wire rope broken string state.The top of standpipe is equipped with the push rod with cathode ash-clearing brush equal number.The upper and lower of standpipe is equipped with limit switch respectively.
Electric heating element to the insulator heating, keeps the insulator drying around the corona wire insulator, avoids dewfall.
The outside of standpipe is with under one and has reverse taper, and the sleeve pipe of tangent air inlet is arranged at top.
In view of above feature, the present invention has following advantage:
1, the inlet dust concentration is big, and 2, air velocity is fast in the electric field, 3, to handle air quantity big, 4, deashing is convenient and reliable, 5, the compact conformation cost is low, and 6, be adapted to purify high specific resistance and strong sticky dust, 7, easy to maintenance, floor space is minimum, and 8, resistive connection reveals, 9, the efficiency of dust collection height.
