Abstract
The invention provides an electric field dust collecting mechanism. The mechanism comprises crossbeams, longitudinal beams, connecting angles, an anode hanging framework, a cathode hanging framework, anode plates, cathode wires, anode shaking rods, air flow through holes and a cathode hanger, wherein the crossbeams and the longitudinal beams are welded on the top of an electric dust collector; the anode hanging framework is fixed on the longitudinal beams through the connecting angles; the anode plates are hung on a hook of the anode hanging framework; air flow through holes on the two neighboring anode plates are staggered; the anode shaking rods are fixed below the anode plates; the cathode hanging framework is fixed on the crossbeams through the cathode hanger; and the cathode wires are hung on the cathode hanging framework. Since the anode plates are vertically arranged in the smoke flow direction and the electric field force direction is consistent with the smoke flow direction, driving speed of charged particles is increased, and fine dust impacts the anode plates by virtue of greater inertia force so as to fully settle; the smoke entering an electric field is further distributed uniformly through the air flow through holes arranged on the anode plates, thus ensuring that air can reach the best turbulence uniform distribution effect; and the smoke can be fully ionized without secondary dust reentrainment, thus improving dust collecting efficiency of the dust collector.
Description
Technical field
The present invention relates to electric cleaner, particularly its electric field mechanism of gathering dust.
Technical background
Along with the promulgation of new atmosphere pollutants emission standards, the concentration of emission of deduster must be controlled at 50mg/Nm
3Below, even lower, this just has higher requirement to the efficiency of dust collection of deduster.
At present, the layout of positive plate is parallel with flue gas flow direction in the electric cleaner, the dust-laden particle is after being ionized through the electric field between positive plate and the cathode line, charged dust at first will overcome its inertia force with air motion and could move to dust collector pole and discharge electrode, this is for the less fine dust of particle diameter, be difficult to overcome its inertia force and be adsorbed to positive plate and cathode line, still because inertia force discharges with air-flow, directly influenced the dust-collecting efficiency of electric cleaner mostly.And reentrainment of dust mostly is the less fine dust of particle diameter during vibration dust-cleaning, airflow uniform distribution device only relies on airflow-distribution board in the import end socket in addition, the airflow uniform distribution effect does not reach perfect condition, exist local wind speed too high, make partial fume sedimentation in time and directly discharging after ionization or the ionization fully with flue gas.Therefore further uniform flue gas, effectively to adsorb charged dust be a key link that improves the electric cleaner efficiency of dust collection.
Summary of the invention
At above problem, the invention provides a kind of electric cleaner electric field mechanism of gathering dust, utilize the positive plate self structure further uniform to the flue gas that enters behind the electric field, and allow it vertically be installed on the direction of flow of flue gas, just the direction with flow of flue gas is consistent for the charged back of dust electric field force direction, increased the migration velocity of charged particle to dust collecting pole plate, make fine dust obtain sufficient sedimentation there to be inertia force to impact positive plate more greatly, escape and effective fine dust of collecting thereby reaching removes smoke, reduce the electric cleaner discharging, improve the purpose of electric cleaner efficiency of dust collection.
The technical scheme that the present invention is adopted for its technical problem of solution is: comprise that crossbeam, longeron, angle cleat, anode hang framework, negative electrode and hang framework, positive plate, cathode line, anode vibrating rod, air-flow through hole, negative electrode and hang.
The case top of electric cleaner is welded with crossbeam and longeron, anode is hung framework and is fixed on the longeron by angle cleat, positive plate hangs over anode and hangs on the hook of framework, have the air-flow through hole on the positive plate, adjacent two positive plate overdraught through holes stagger, and hang with cathode line between adjacent two positive plates.The positive plate below is fixed with the anode vibrating rod.
Crossbeam is fixed in the case top of electric cleaner, and negative electrode is hung framework and hung by negative electrode and be fixed on the crossbeam, and cathode line hangs over negative electrode and hangs on the framework.
Positive plate vertically is installed on the flow of flue gas direction, and the electric field force direction is consistent with the flow of flue gas direction, has increased the migration velocity of charged particle, and fine dust impacts positive plate and obtains sufficient sedimentation with big inertia force.After dust entered electric-field charge, positively charged dust-laden particle and positive plate repelled each other, and moved to cathode line, and absorption back dead electricity is assembled the back and is being deposited on next row's positive plate by inertia force under the drive of air-flow.Electronegative dust-laden particle is inhaled mutually with positive plate, directly impacts the positive plate sedimentation.
The air-flow through hole of opening on the positive plate makes the flue gas enter behind the electric field obtain further uniform, adjacent two positive plate overdraught through holes stagger make flue gas pass through last row's positive plate after, the air-flow through hole that enters next row's positive plate must change certain direction and just can enter, guaranteed that gas reaches best turbulent uniform effect, do not exist local flue gas flow rate too high and situation that electric field has little time to handle is avoided the direct escape of flue gas in the electric field in the flue gas.
The positive plate spacing is 380～450mm, and the air-flow through-hole aperture on the positive plate is Φ 50～Φ 80mm, and the air-flow through hole number on every square metre of positive plate is 16～24.Air-flow through-hole aperture on the positive plate changes according to the positive plate spacing, and the positive plate spacing is little, and then the aperture is little, and the positive plate spacing is big, and then the aperture is big.
And the flue gas in the electric field need be through laterally moving the air-flow through hole that just can enter next row's pole plate, the time of staying lengthening of flue gas in region of discharge, the dust-laden particle can be by abundant ionization, flue gas flow rate increases through the air-flow through hole time, after the collection ash of being taken away by air-flow on the cathode line quickened, more dust can borrow inertia force to be deposited on the positive plate.Simultaneously during vibration dust-cleaning, because reentrainment of dust is in positive plate surface low regime, most dust just has enough sedimentation times and freely drops in the ash bucket.
Beneficial effect of the present invention is: the airflow uniform distribution effect is fine in the electric field, the ionization fully of flue gas energy quilt, and can not produce the dirt reentrainment of dust substantially, and effectively captured fine dust, improved the efficiency of dust collection of deduster.
