Description
Technical field the utility model relates to a kind of Environmental-protecting dust-removing equipment-field constraint deduster
The dust-cleaning principle of the technical background domestic and international high-voltage electrostatic dust separator for administering dust pollution is at present that dust is charged, and charged dust tends to control of dust plate and deposits under the effect of electric field force.Electrostatic precipitator structure is simple, but lower to micro mist dirt efficiency of dust collection.
The object of summary of the invention the utility model field constraint deduster is that proposing a kind of electric field and magnetic field of adopting retrains charged dust, thus carry out the electric cleaner of gas solid separation, it is by air intake vent, housing, plate, corona discharge electrode, magnetic group, grid, insulating barrier, suspend naked grid, the naked grid of ground connection, air outlet, high voltage source, first pole of high voltage source, second pole of high voltage source and current limiting element form, it is characterized in that: set into air port at housing left end, air port is set out at housing right-hand member, plate and corona discharge electrode are set enclosure interior is alternate, on plate or permanent magnetism group is set, grid and insulating barrier form insulated gate electrode, on the right side of plate or arrange insulated gate electrode, or the naked grid that suspends is set, or the naked grid of ground connection is set, first pole of high voltage source is connected with housing and ground connection, second pole of high voltage source is connected with corona discharge electrode by current limiting element, plate, insulated gate electrode, the naked grid of ground connection is connected with housing and ground connection, the naked grid that suspends extremely is connected with second of high voltage source.High voltage source can adopt DC high-voltage power supply, or adopts alternation high voltage source.
Insulated gate electrode, the naked grid that suspends, the naked grid of ground connection are made up of expanded metal lath or screen material, has good electric conductivity and gas permeability.Can planar structure be adopted, or adopt the structure such as fold plane, arch face, to increase filter area, reduce resistance and gain in strength.
So-called insulated gate electrode refers to the surface coverage insulating barrier at conductive grid, and so-called naked grid refers to surperficial naked layer, and the naked grid of ground connection is exactly this electrode and the same current potential in ground, does not produce corona discharge between the naked grid of ground connection and corona discharge electrode.The so-called naked grid that suspends is exactly that this electrode insulate with ground, does not produce electric discharge with plate.
When dust-contained airflow flows through the space of plate and corona discharge electrode, gas produces corona discharge, produces cation and electronics, and dust is by how negative electricity or positive electricity simultaneously.
Electronics and electronegative dust are called negative particle, and the dust of cation and positively charged is called positive corpusc(u)le.Negative particle and positive corpusc(u)le are referred to as charged particle.
Permanent magnetism group composition magnetic mirror relative on two plates, the magnetic field of magnetic mirror is to the effect of charged particle Constrained, insulated gate electrode, or the first pole of suspend naked grid or the naked grid of ground connection and high voltage source or the second pole connect, the electric field that insulated gate electrode, suspend naked grid and the naked grid of ground connection are formed is to the motion Constrained effect of charged particle.
