Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is further described:
A kind of low temperature spiral corona plasma VOCSEmission-control equipment, as shown in Figure 1 to Figure 3, including low temperature spiral corona plasma reactor and electrode body plate 1, electrode body plate 3, extremely rod plate 4, extremely rod plate 5, the insulation porcelain knob 2 of multiple parallel connections.Described low temperature spiral corona plasma reactor is made up of spiral prickle extremely rod 6 and pipe electrode body 7, spiral prickle extremely rod is co-axially located in pipe electrode body, spiral prickle extremely rod connects the positive pole of AC-DC overlaying power, pipe electrode body connects the negative pole of AC-DC overlaying power, spiral prickle extremely rod and pipe electrode body all use stainless steel material to make, and uniform are shaped with prickle 8 spiral prickle is the most excellent.The pipe electrode body two ends of each low temperature spiral corona plasma reactor are connected with electrode body plate respectively, the spiral prickle of each low temperature spiral corona plasma reactor extremely rod two ends are connected with extremely rod plate respectively, two electrode body plates connect the negative pole of AC-DC overlaying power, two extremely excellent plates connect the positive pole of AC-DC overlaying power, and each electrode body plate is installed together by four insulation porcelain knobs with extremely rod plate.The electron energy that the electric discharge of low temperature spiral corona plasma reactor produces is the highest, and low-temperature plasma density is big, reaches 1500 times of conventional plasma technology (corona discharge), almost can be with all of VOCSAnd stench gas with foreign flavor molecular action；VOCSAnd stench gas with foreign flavor clearance reaches 80%-98%.Oil smoke clearance 90%-98%.
It is known that, although Helicon wave plasma have electron density high and uniformly, confining magnetic field is low, have the features such as extraordinary ionizing efficiency, but, because its occurring mode is to be made magnetic line of force generation disturbance by the effect of electromagnetic wave, become spiral line, there is the problem that application conditions is limited, should not use as exhaust-gas treatment.Low temperature spiral corona plasma reactor is made up of spiral prickle extremely rod and pipe electrode body, high density, broadband ion beam is produced under the effect of AC-DC overlaying power, by plasma occurring mode and channel parameters structure, produced helical magnetic force line by spiral prickle extremely rod and pipe electrode body structure, ultimately form low temperature spiral corona plasma reactor.It is high and uniform that plasma has electron density, and confining magnetic field is low the features such as extraordinary ionizing efficiency.
Work process of the present utility model is: when applied voltage reaches the discharge voltage of gas, gas is breakdown, produces the mixture including electronics, various ion, atom and free radical.Although electron temperature is the highest in discharge process, but heavy particle temperature is the lowest, and whole system presents low temperature state, so referred to as low temperature plasma.Low-temperature plasma degradation pollutant are to utilize the pollutant effect in these high energy electrons, free radical isoreactivity particle and waste gas, make contaminant molecule decompose within the extremely short time, and occur follow-up various reactions to reach the purpose of degradation of contaminant.(note: low temperature plasma, for high-temperature plasma, belongs to room temperature and runs.) this plasma reaction zone is rich in high material, such as high energy electron, ion, free radical and excited state molecule etc., polluter in waste gas can react with these materials with higher-energy, make polluter decompose within the extremely short time, and occur follow-up various reactions to reach the purpose of degradation of contaminant.The basic process that this utility model removes pollutant is as follows:
