Description
Technical field
The present invention relates to a kind of plasma odor treatment device.
Background technology
Foul gas is meant that mainly all stimulate organum olfactorium to cause the gaseous matter that people are unhappy and damage living environment, and its composition is complicated especially, comprises hydrogen sulfide, mercaptan, ammonia, amine, hydro carbons etc.Be mainly derived from commercial production, municipal wastewater, Treatment of Sludge and waste treatment facility etc.These gases all can cause in various degree infringement to human body respiration, digestion, cardiovascular, endocrine and nervous system etc.And deodorization in most cases is meant and removes the gas with penetrating odor of sneaking in the air, thereby makes the air quality of discharge can reach the requirement of " discharge standard of air pollutants " and " odorant pollutant discharge standard " of country's promulgation.
Conventional deodorization technology has absorption process, absorption method, firing method, chemical oxidization method, biological filter process etc.It is low that these methods all exist purification efficiency, and the Purge gas kind is single, and the control difficulty is big, and the energy consumption height takies shortcomings such as volume is big.
And the various in recent years devices of Low Temperature Plasma Treating foul smell technology that utilize constantly occur, and are not good but their ubiquities the foul gas treatment effect, and the gas after the deodorization does not carry out after-treatment, easily cause secondary pollution problem.
Summary of the invention
The object of the present invention is to provide a kind of novel plasma odor treatment device, to solve the technical problem of in the environment of normal temperature and pressure, effectively removing foul smell.
A kind of novel plasma odor treatment device of the present invention, it comprises power supply, plasma deodorizing reactor, blower fan and scrubbing tower; The plasma deodorizing reactor is connected with scrubbing tower; In the pipeline of blower fan between reactor and scrubbing tower, the junction of reactor and blower fan is connected with one section insulant.
Described a kind of novel plasma odor treatment device, described power supply adopts high-voltage pulse power source or HVDC superimposed pulse power supply; The peak impulse voltage of power supply is adjustable in 10 to 1000 kilovolt range, and the impulse waveform rise time, frequency was adjustable at 10-100KHz between 1 nanosecond to 100 nanoseconds.
Described a kind of novel plasma odor treatment device, reactor is made up of electrode respect to one another.One of them electrode is to be made of the some equidistant parallel connections of corona wire that have sawtooth, and adjacent sawtooth is dislocatedly distributed on the every corona wire; Another electrode is to be made of slick corrosion resistant plate, and each pole plate is parallel to each other, and corona wire is positioned at the pole plate middle; Corona wire and polar board surface all scribble insulant.
Described a kind of novel plasma odor treatment device, the reactor corona wire links to each other with positive source, and corrosion resistant plate links to each other with negative pole and ground connection, constitutes the positive streamer discharge; Or corona wire links to each other with power cathode and ground connection, and corrosion resistant plate links to each other with positive source, constitutes negative streamer-discahrge.
Described a kind of novel plasma odor treatment device has the circulating pump of circulated sprinkling cleaning mixture, scrubbing tower top to have to remove the demister of the solution vapor that the washing back produced in the scrubbing tower.
The present invention has following advantage:
1, use multi-group electrode to connect mutually, with the odor removal efficient of enhancing reactor.
2, blower fan is between reactor and scrubbing tower, can timely the gas that generates in the reactor be sent in the scrubbing tower, accelerate gas flow in the reactor, can also improve deodorant efficient according to the flowing velocity of foul smell in the variable concentrations conditioned reaction device of foul smell.
3, spray and demister are arranged in the scrubbing tower, the deodorization product is absorbed, remove fog by demister then, effectively inhibitory reaction product secondary pollution that environment is caused by circulating pump circulated sprinkling cleaning mixture.
Description of drawings
Fig. 1 is a structure principle chart of the present invention.
Fig. 2 is the structure chart of deodorizing reactor of the present invention.
Fig. 3 is the corona wire cross section structure figure of deodorizing reactor of the present invention.
The specific embodiment
Structure of the present invention is referring to Fig. 1, and this device has foul smell inlet 1, power supply 2, plasma deodorizing reactor 3, blower fan 4, scrubbing tower 5, circulating pump 6, spray equipment 7, demister 8.Wherein power supply can use high-voltage pulse power source, also can use the dc pulse superposition power supply.Wherein peak impulse voltage can reach 10 to 1000 kilovolts adjustable, the rise time, frequency was adjustable at 10-100KHz between 1 to 100 nanosecond, they can produce stable streamer-discahrge in reactor.
Referring to Fig. 2, corona wire 3-1 is wherein arranged, pole plate 3-2.Deodorizing reactor 3 is made up of electrode respect to one another, and one of them electrode is to be made of the some equidistant parallel connections of corona wire 3-1 that have sawtooth, and every corona wire 3-1 goes up adjacent sawtooth and is dislocatedly distributed.Corresponding electrode is a slick pole plate 3-2, and both are parallel to each other.Surface at two electrodes all scribbles insulant.Positive source links to each other with corona wire 3-1, and negative pole links to each other with stainless steel polar plate 3-2 and ground connection, constitutes the positive streamer discharge; The ground connection that also can power cathode links to each other with corona wire 3-1, and anodally link to each other with stainless steel polar plate 3-2, constitute and bear streamer-discahrge.But no matter which kind of connects, must be reliable, firm.
Referring to Fig. 3, the sawtooth angle of the corona wire of band saw tooth is approximately 60 °.The corona wire 3-1 of band saw tooth helps forming stronger field intensity on its surface, when applying hf and hv pulse voltage or dc pulse superposition voltage between two electrodes when, will form streamer-discahrge between the electrode, produces plasma.Simultaneously, we can also use multi-group electrode to connect mutually, with the odor removal efficient of enhancing reactor.This reactor can increase or reduce the logarithm and the group number of electrode according to the needs of actual treatment foul smell.By regulating the coupling between power supply and the reactor, can in reactor, produce stable streamer-discahrge.
Blower fan 4 is connected in reactor 3 afterbodys, in time the foul smell of handling in the reactor 3 is taken away and is sent in the scrubbing tower 5, accelerates gas flow in the reactor 3, can also improve deodorant efficient according to the flowing velocity of foul smell in the variable concentrations conditioned reaction device 3 of foul smell.Reactor 3 is connected with one section insulant with the junction of blower fan 4.
