Abstract
The utility model discloses an external alternating magnetic field-based electrostatic cyclone dust removal system and belongs to the field of electrostatic dust removal. The utility model mainly solves the technical problem that wind resistance is increased by an internally-applied magnetic field and aims to prolong the time that particles spend in an electric field. The external alternating magnetic field-based electrostatic cyclone dust removal system consists of a smoke inlet, a cylindrical ferrite, a round silicon steel sheet, a dust collection slot, a cylindrical coil, a smoke outlet duct, a high-voltage linear electrode, a high-voltage tubular electrode, an alternating current power supply and a cyclone separator cavity, and is characterized in that the cylindrical ferrite sheathed with the cylindrical coil is connected with the round silicon steel sheet welded on the wall of the cyclone separator cavity. The particles do a Larmor motion under the action of electric field force and Lorentz force, thus, the action time of the particles in the electric field is prolonged. As the polarity of the magnetic field is changed along with applied alternating current, when the particles move to break away from the electric field, the direction of a Lorentz force applied to the particles is changed, and the particles enter an electric field area again, so that the charging time of the particles is prolonged. The external alternating magnetic field-based electrostatic cyclone dust removal system is mainly used for the field of the electrostatic cyclone dust removal.
Description
Technical field
The utility model belongs to the electrostatic precipitation field, refers in particular to a kind of static cyclone system of strengthening based on outer alternation magnetic.
Background technology
Recently medical research shows that the generation of lung cancer is in rising trend, and particularly non-smoker's lung cancer incidence is in rising trend too.The appearance of existing this situation of bibliographical information is in close relations with PM2.5.PM2.5 refers to aerodynamic diameter less than 2.5 microns particle, and it can adsorb various noxious materials and directly enter the human body lower respiratory tract.Generally acknowledge that now PM2.5 is one of pollutant.
Thermoelectric enterprise, the employed fire coal of heating enterprise are one of important sources of PM2.5, thereby are the important means that suppress PM2.5 to the improvement of these enterprise's emissions.The mixing dust removing system that static combines with cyclone dust removal in numerous improvement methods is a kind of comparatively desirable method.Electrostatic precipitation mainly is to be adsorbed and to remove by charging particle.Cyclone dust removal is a kind of traditional dust collection method, and mainly the centrifugal force that produces by the air-flow of high speed rotary motion separates particle, has characteristics simple in structure, that cost is low, but its to the control action of particulate a little less than.Electrostatic precipitation is better to the control action of fine particles, is a kind of comparatively desirable schemes with both combinations therefore.Although the two is in conjunction with being a kind of good way, the clearance for molecule can't reach satisfaction, increases magnetic field on the basis of static whirlwind for this reason.Charged particle can produce complicated Rameau motion under the effect in magnetic field, make charged particle time of staying in handling electric field lengthen.Have the researcher magnet to be placed in the high-voltage electrostatic field, thereby add magnetic field in forming, but magnet increases very big windage in electrostatic field.Adopt permanent magnet poles that charged corpuscle time of staying in electric field is fallen short of simultaneously, adopt alternating magnetic field can make charged corpuscle stop the longer time at electric field.Increase the problem of windage and make particulate the utility model proposes a kind of static cyclone system of strengthening based on outer alternation magnetic in the electric field stop longer time in order to add magnetic field in overcoming.It can address the above problem effectively.
Summary of the invention
Increase the not enough of windage and prolong the time of particulate in electric field in order to add magnetic field in overcoming, the utility model proposes a kind of static cyclone system of strengthening based on outer alternation magnetic, this system not only can reach the purpose that improves efficiency of dust collection but also can reduce windage, thereby reaches the optimum efficiency of dedusting.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model device is formed by advancing mouth, cylindric ferrite, circular silicon steel sheet, dust collecting trough, cylindric coil, smoke outlet flue, high pressure wire electrode, high pressure tubular electrode, AC power, cyclone separator cavity, it is characterized in that the cylindric ferrite that is with cylindric coil links to each other with the silicon steel sheet that is welded in the circle on the cyclone separator cavity wall.
Because the cyclone separator cavity body is to be welded with steel plate, externally adding magnet can be by the shielding of the metallic walls of cyclone separator cavity, so on the sidewall with the cyclone separator cavity, cut out a circular port close to high pressure tubular electrode place.Circular silicon steel sheet with homalographic is welded in the circular port.With circular silicon steel sheet adhesion, cylindric coil is wrapped on the cylindric ferrite with cylindric ferrite end.The two ends of coil link to each other with AC power.
Under the wind-force effect of flue dust at air-introduced machine, enter the cyclone separator cavity through the circular mouth that advances.The centrifugal force that the air-flow of high speed rotary motion produces will produce centrifugation to larger particles.Bigger particle will be to the motion of chamber wall under action of centrifugal force, and dust collecting trough is gone in last landing.Subparticle is subjected to centrifugal action little, but is added with corona discharge electrode (high pressure wire electrode) and high pressure tubular electrode plate at cyclone separator cavity main shaft place, will produce the effect of electric field force to it; Owing to add the effect of alternating magnetic field, make charged particle be subjected to the effect of Lorentz force simultaneously.Microparticle is done complicated Rameau motion under the acting in conjunction of electric field force and Lorentz force, prolonged the action time of particle in electric field, makes that particle can be charged fully.Since polarity of the magnetic field with adding alternating current change.When the microparticle motion will be broken away from electric field, because polarity of the magnetic field changes, cause its suffered Lorentz force direction to change, enter electric field region again, the charged time of particulate is prolonged, and charged particle is with there not being charged particle collision can make it charged.Fully charged particle is finally caught by the cyclone separator cavity wall under the effect of electric field force.To be discharged by cylindric smoke outlet flue through the flue dust after cyclonic separation and the high-pressure electrostatic processing.
The alternating magnetic field change frequency is flow through the influence of the electric current in the coil.Electric current is provided by AC power.
The beneficial effects of the utility model are can prolong the time of microparticle in electric field, to reach the optimum efficiency of dedusting.It is mainly used in static cyclone dust removal field.
