Description
Technical field
The utility model belongs to electrostatic precipitation field, refers in particular to a kind of charge device based on microwave.
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 the particle that aerodynamic diameter is less than 2.5 microns, and it can adsorb various noxious materials and directly enter human body lower respiratory tract.Generally acknowledge now that PM2.5 is one of pollutant.
The fire coal that Thermal Power Enterprises, heating enterprise are used is one of important sources of PM2.5, thereby the improvement of these enterprise's emissions is the important means that suppresses PM2.5.In numerous improvement methods, static is a kind of comparatively desirable method.Electrostatic precipitation is mainly by charging particle, is then adsorbed and removes.Although this is a kind of good way, the clearance for molecule can't reach satisfaction, and this is because near the particle of kinetic diameter 1 micron is very difficult charged, because particle band is not gone up electric charge, so can not be adsorbed by Electrode.This phenomenon is referred to as window effect by static educational circles.In order to make atomic chargeability increase, people have adopted several different methods, and as increased magnetic field etc., but effect is all unsatisfactory.The utility model proposes a kind of charge device based on microwave, it can address the above problem effectively.
Summary of the invention
In order to promote the chargeability of microparticle, the utility model proposes a kind of charge device based on microwave.
The utility model solves the technical scheme that its technical problem adopts: the utility model device is comprised of high pressure tubular electrode, insulating support, high pressure wire electrode, microwave generator, vertical heating flue wall, vertical heating flue, horizontal flue wall, horizontal flue, it is characterized in that: columniform microwave generator is positioned on horizontal flue wall and in vertical heating flue bottom, high pressure tubular electrode cylindraceous is connected with vertical heating flue wall by insulating support.
Microwave generator, horizontal flue, vertical heating flue, high pressure wire electrode are cylindrical structural; High pressure tubular electrode is cylinder-like structure.
Under the effect of air-introduced machine, flue dust enters cylinder horizontal flue, by the horizontal flue of level, proceeds to vertical vertical heating flue.Below the junction of horizontal flue and vertical heating flue, a microwave generator is installed.The waveguide of microwave generator upwards.Thereby the powder dust particle that enters vertical heating flue can be subject to the effect of microwave.
When powder dust particle continues to move along vertical heating flue, enter in the electric field being formed by high pressure wire electrode and high pressure tubular electrode.Near high pressure wire electrode, can produce corona, ionize out negative ions.Be subject to the effect of electric field, charged particle is to contrary electrode movement.Charged particle is by under the effect of electric field force, to its charged opposite polarity battery lead plate motion, in motion process, charged particle may meet with dust granules, bearing thereon, make dust granules become charged particle, to dust collecting pole plate motion (being generally high pressure tubular electrode), be finally attached on dust collecting pole plate.
In the used time of doing that there is no microwave, some dust granules, particularly kinetic diameter, at the particle of 1 micron of left and right, are difficult to meet with charged particle, also seldom adsorb charged particle, the famous window effect in electrostatic precipitation field that Here it is even if meet.
Due on horizontal flue wall, the below of vertical heating flue is provided with microwave generator, and its waveguide is launched microwave vertically.Microwave makes particulate produce vibration, and atomic energy increases, and makes it be easy to attract electrons.Meanwhile, microwave is also conducive to the formation of corona, can ionize out more free electron and positive charge.Under the acting in conjunction of the two, make the clearance of dust particle increase.
The beneficial effects of the utility model are can promote microparticle chargeability, to reach the optimum efficiency of dedusting.It is mainly used in electrostatic precipitation field.
