Description
Technical field
The utility model belongs to the flue gas purifying equipment of environmental protection, is specifically related to a kind of self-cleaning type permanent magnet ground connection corona discharge utmost point flue gas cleaner.
Background technology
At present, known flue gas cleaning equipment by corona discharge depends primarily on its core component-corona discharge utmost point to the removal efficient of pollutant.The discharge performance that strengthens the corona discharge utmost point is the effective measures that improve purification utensil efficient, and particulate pollutant is the main cause that clarifier efficient constantly reduces to the pickup of electrode in the flue gas, improve purification utensil efficient and will manage to address this problem.
Summary of the invention
The purpose of this utility model is exactly to solve that particulate pollutant reaches the stable and high effective operation of long-term maintenance clarifier to the pickup problem of clarifier electrode in the flue gas.
The purpose of this utility model is achieved in that flue gas cleaner is divided into shell, ground connection atomizing discharge, high voltage collector and water and electricity supply four systems.
Self-cleaning type permanent magnet ground connection corona discharge extremely vertically is placed on the circle central axis of cylindrical shape high pressure collecting electrode.During the equipment operation, because the rounded edge of ground connection discharge electrode cylindrical permanent magnet has minimum radius of curvature and extremely nearest from the cylindrical shape high pressure collecting.Thereby under the electrostatic induction of the high pressure collecting utmost point, electric-field intensity is very high near the magnet seamed edge, is enough to produce gas ionization and forms corona discharge.Yet, because permanent magnet can produce the strongest magnetic field near circular crest line, and the magnetic line of force in magnetic field and the power line of highfield intersect, free electron herein is subjected to the Lorentz force effect and produces the Rameau motion, increased considerably the ionizing collision probability of free electron, made the corona discharge current of discharge electrode obtain at double growth.Meanwhile, water system makes constantly flow through the from top to bottom seamed edge of permanent magnet of recirculated water, and the corona discharge of enhancing can produce strong electrostatic atomization.When water droplets is left the permanent magnet discharge electrode,, when passing the gas discharge ionized region, carry a large amount of-OH and O again then because of responding to charged a large amount of electric charges that have
3The isoreactivity species.Thereby when these water droplets leapt between ionized region and the cylindrical shape high-field electrode broad regions, charged drop had improved the efficiency of dust collection of clarifier to particulate pollutant coalescence and washing in the flue gas; Simultaneously, the drop that has an active specy is oxidized to harmless or nontoxic material with the pernicious gas in the flue gas effectively.At last, drop collides extremely surface of cylindrical shape high pressure collecting.The electrostatic atomization process of discharge electrode surface recirculated water has played the effect of the automatic discharge cleaning utmost point, and drop is to the cleaning that has also kept the high pressure collecting utmost point effectively of washing away of the cylindrical shape high pressure collecting utmost point.
Recirculated water is arranged, so metal parts mainly adopts stainless steel when moving because of this equipment.Main casing can use 15X15X2 stainless steel angle steel to be processed into; It is the 76mm stainless steel cylinder that the cylindrical shape high pressure collecting utmost point can adopt diameter; Square chest type high-field electrode can adopt the thick corrosion resistant plate bending of 2mm to form; The stainless steel column of 2cm is welded on the thick 70X50mm corrosion resistant plate of 3mm makes fixed support; Nylon material is processed into the pyramidal structure that the top has screw makes insulated leg; Water pipe is φ 25PVC pipe, uses the PVC glue special bonding between water pipe; Except that the smoking port of the exhaust opening on clarifier top and bottom, case surface covers sealing with the 1mm corrosion resistant plate.
The utility model is under the condition that does not increase the clarifier volume, and the discharge performance of the enhanced discharge utmost point improves purification utensil efficient significantly. simultaneously, in the clarifier running, thus the constantly automatic discharge cleaning utmost point. keep the stable and high effective operation of clarifier for a long time.
