Description
Technical field:
The present invention relates to a kind of waste gas purification apparatus, a kind of specifically low temperature plasma waste gas cleaning device that can purify multiple waste gas.
Background technology:
Present used waste gas purification apparatus mainly is made up of housing, field generator, the pulse power, and field generator is made negative plate by the black iron plate, and the positive plate that strings together is done positive pole; The both sides of positive plate are profile of tooth; As discharge electrode, and between per two negative plates one group of positive plate is arranged, anodal pointed tooth is facing to the plane of negative plate; Barnyard between the positive/negative plate is an electric field, i.e. the passage that flows through of waste gas.Because the space of passage is big, and is without hindrance, when receiving effect on structure waste gas to flow through each passage, mass flow discrepancy is even, and because the stroke of electric field is short, the time of the stop of waste gas in electric field is also short, causes exhaust purification efficiency low; Because of reasons in structure, the electric field in the purifier exists highfield, weak electric field and does not have electric field region, and when positive pole during to negative discharge, electronics is moved to negative pole by positive pole, and drives waste gas stream continuously to the negative pole motion, produces the electronics air curtain.When waste gas gets into electric field from the side, receive the influence of electronics air curtain to produce resistance, though forceful electric power place purification efficiency is higher; But the flow of waste gas is little; Do not have purification function and there is electric field region, but the flow of waste gas being maximum, is to cause exhaust purification efficiency to hang down another key factor.
Summary of the invention:
In order to overcome the existing low problem of waste gas purification apparatus purification efficiency, the present invention provides a kind of low temperature plasma waste gas cleaning device.This device has increased waste gas through stroke, adopts two-step purification pattern and duplicate supply system, makes that waste gas through purifier is evenly distributed, flow velocity slows down, and improves the electric field strength of discharge, thereby has improved exhaust purification efficiency greatly.
Technical scheme of the present invention is: low temperature plasma waste gas cleaning device; Comprise casing and be fixed on the circuit board case on the casing; The interior fixedly movement of casing; And connect with circuit in the circuit board case by circuit; Movement embedded have negative plate and a positive plate, in described movement, also is equipped with punched-plate, and the distributing position of negative plate, positive plate plate and punched-plate is: middlely be negative plate; Both sides symmetry respectively are equipped with punched-plate and positive plate successively, and the outside of two positive plates is followed successively by punched-plate and negative plate; And distribute on the punched-plate some delthyriums and coupled triangular plate, and triangular plate tilts to the negative plate direction; Between inlet end negative plate and punched-plate, fix, fix by sealing insulation board C between middle two punched-plates, and sealing insulation board C and two seals insulation board B by insulation connecting plate E connection by sealing insulation board B; Fixed by sealing insulation board C between exhaust end two punched-plates, two sealing insulation board C are connected by insulation connecting plate D.
Circuit in the described circuit board case mainly by rectification filtering unit, pulse output unit, high pressure output unit, driver element, and the voltage display unit form; The low level end of described rectification filtering unit connects with the low pressure input of high pressure output unit, and the high level end of rectification filtering unit connects the input of voltage display unit and driver element successively; And the output of driver element connects the high voltage input terminal of pulse output unit and high pressure output unit successively.
Fix by hold-down screw through the dihedral connecting plate between described casing and movement; Described positive and negative pole plate and punched-plate are respectively 2,3,4; Described sealing insulation board B, sealing insulation board C, insulation connecting plate E and insulation connecting plate D are respectively 2,3,2,2.
The invention has the beneficial effects as follows: owing in movement, increase the punched-plate that has delthyrium and triangular plate, waste gas has played shunting and slowed down flow velocity when getting into purifier effect, thus make the waste gas distributions even, improve purification efficiency; The triangular plate that is connected with delthyrium simultaneously can be used as the positive pole that discharge electrode promptly discharges, after waste gas gets into purifier, behind the plane and the purification of the discharge field between positive plate through punched-plate; When getting into the discharge field between triangular plate and negative plate through delthyrium again; Place, tip at triangular plate forms point-to-point purification pattern, is purified once more by the discharge field between triangular plate and negative plate again; Form bipolar purification pattern, further improve exhaust purification efficiency.Because this adopts the duplicate supply system, also improved the strength of discharge of electric field simultaneously, improved exhaust purification efficiency once more.
