Abstract
This invention relates to gas melt deionization device with high voltage and field charge, which comprises the following parts: inner axis electrode distributed with outside electrode to support inner axis electrode front and back rack; front and back end cover set on both ends of electrodes; holes on front and back rack with gas melt entrance and exit holes with one conductive detector imbedded at inner axis electrode entrance end connected to the high voltage power; the outside cylinder electrode is connected to earth to form high voltage field.
Description
Technical field
The present invention relates to a kind of discharge system, relate in particular to a kind of high voltage electric field that utilizes and eliminate the charged device of charged aerosol.
Background technology
Aerosol is a liquid or solid with diameter is the dispersion that the Dispersion of Particles of 0.002～100 μ m forms in gas medium.Aerosol has bigger specific surface, may be charged in several ways, and electrically charged amount does not wait and can change along with the time, the positive and negative external environmental condition that depends on of electric charge.Measuring instrument demarcate or multiple operating process such as filtering product Performance Detection in, need to use neutral or have the unicharged aerosol of stable state, this moment must demarcate or detecting operation before, to the charged aerosol electric treatment that disappears.
Mainly contain three kinds of aerosol deionization technologies at present in the prior art: radiation deionization technology, corona deionization technology and static deionization technology.The radiation deionization technology mainly uses Krypton 85 (Kr85) and polonium 210 radioactive substances such as (Po210), utilizes radioactive substance to produce the ionization of ray, and charged aerosol is neutralized; The corona deionization technology mainly uses the form of point discharge to produce negative ions, thus in and aerosol institute electrically charged; The static deionization technology then utilizes high voltage electric field to capture charged particle in the aerosol, reaches the disappear purpose of electricity of aerosol.The major defect of radiation deionization technology has: the poor stability of Krypton 85 (Kr85) and polonium 210 radioactive sources such as (Po210), and in buying, transportation, storage, use, management, and all there is very big potential safety hazard in the aspects such as treatment and disposal in useless source; Can only be effective to low discharge, low concentration, aerosol that initial charge is low; The radiation discharge system costs an arm and a leg.In the present electric product that disappears to use the radiation electric mode that disappears the most common.The major defect of corona deionization technology has: the negative ions quantity difference that electrode produces, and the electricity back aerosol that disappears can have excessive single electric charge; The electric process that disappears can produce harmful ozone; In the electric process that disappears, thereby because sputter, aerosol chemistry reaction and electrode chemical reaction produce unnecessary particle.
Compare preceding two kinds of deionization technologies, the static deionization technology that uses in the product of the present invention can utilize high voltage electric field to capture charged particle, aerosol is reached disappear fully the purpose of electricity, and uses economic, safety, reliable.
Summary of the invention
The object of the invention provide a kind of utilize the static deionization technology to aerosol disappear the electricity device, use the existing many safety issues of radioactive source in the present prior art to solve, it is simple in structure that it is had, easy to operate, investment and the low characteristics of maintenance cost.
Product technology scheme of the present invention is:
A kind of aerosol discharge system is characterized in that: this device comprises inner axis electrode, with the outside electrode of inner axis electrode arranged concentric, is used to support the front and back support of inner axis electrode, is arranged on the front and rear cover at electrode two ends; Be respectively equipped with through hole on described front and back support, be respectively equipped with aerosol air inlet and venthole on front and rear cover, embed a conducting probe at the inner axis electrode entrance point, this probe forces down the stream power supply with height and is connected outside electrode ground connection.
Distance between inner axis electrode of the present invention and the outside electrode is 4mm～40mm
The present invention compared with prior art, the present invention has following advantage and high-lighting effect:
The present invention is by the electric field force effect of positive and negative polarities high voltage electric field, the charged particle of attraction and capture charged aerosol is to the two poles of the earth, the acquisition electric colloidal sol that disappears, thereby effectively avoid using tradition disappear Krypton 85 (Kr85) and polonium 210 radioactive substances such as (Po210) in the method for electrically, under the more excellent situation of action effect, the existing many safety issues of use radioactive source have been solved., simple in structure, easy to operate, safeguard that simply, investment and maintenance cost are low.

Embodiment
Below in conjunction with accompanying drawing principle of the present invention, structure and the course of work are further described.
Fig. 1 is the structural representation of the embodiment of aerosol discharge system provided by the present invention.This device comprises inner axis electrode 10, with the outside electrode 4 of inner axis electrode arranged concentric, is used to support fore-stock 6, the after-poppet 3 of inner axis electrode, is arranged on front end housing 7, the rear end cap 2 at electrode two ends; Be respectively equipped with through hole on described front and back support, be respectively equipped with aerosol air inlet 8 and gas outlet 1 on front and rear cover, embed a conducting probe 5 at the inner axis electrode entrance point, this probe forces down the stream power supply with height and is connected outside electrode ground connection.Rear end cap 2 and outside electrode 4, outside electrode 4 and fore-stock 6 are respectively by being threaded; After-poppet 3 compresses by rear end cap 2 and outside electrode 4; Fore-stock 6 is connected by screw thread or form of flanges with front end housing 7.
The course of work of the present invention is as follows: the center circle pipe electrode connects height and forces down the stream power supply, and the on-load voltage scope is 1kV～10kV, and outside electrode ground connection makes and forms the positive and negative polarities high voltage electric field in the discharge system cavity; Introduce the charged aerosol of 300L/h～6000L/h flow from the air inlet of discharge system, the charged particle that enters discharge system is under the effect of electric field force, be attracted and trap respectively on two electrodes, reach the electric purpose charged aerosol that disappears by discharge system and flow out from the gas outlet.
The aerosol discharge system of the invention is applied in the efficient mask filtration efficiency checkout gear, the aerocolloidal carried charge of solid sodium chloride of 5400L/h flow is eliminated to 10fA by original 1pA, (using TSI-3068 aerosol electrostatic instrumentation amount), reduce by 100 times, reached the good electric effect that disappears.
