Detailed description of the invention
As shown in Figure 1, a kind of low-temperature plasma equipment for the purification of garbage transfer station foul gas, comprise shell 2, air inlet 1 and air outlet 8, also comprise: double-dielectric barrier discharge system, power-supply system, high pressure converting system, cloth wind flow guide system 3, spray irrigation system.
Wherein, double-dielectric barrier discharge system, comprises multiple discharging tray 5, discharging tray 5 plurality of rows is arranged in shell 2, and double-dielectric barrier discharge frequency 5000-30000Hz is pulsed discharge, discharge electrode is positive pole and negative pole each other, belongs to bilateral electric discharge, and each second, discharge time was 10000-60000 times.Double-dielectric barrier discharge voltage is greater than 20000 volts, and the energy of the high energy electron of generation is greater than 8eV, higher than the energy needed for the cracking of most of odor molecules scission of link.
High pressure converting system, comprises the high voltage package 6 that quantity is identical with discharging tray 5 quantity, and 380V input voltage is converted to 20000V electrion voltage by high pressure converting system, and wherein, discharge voltage is higher, and the energy of the high energy electron of generation is larger.
Because discharging tray 5 is adhered to by the stickum in waste gas, fouling can affect discharge effect, for keeping discharging tray 5 clean, spray irrigation system is set in low-temperature plasma equipment, this system comprises atomization metal nozzle 4, stainless steel connecting hose, PPR vibration means for main pipe for supplying water, magnetic valve, be connected with the resource of water supply of more than external water pressure 3bar, the corresponding discharging tray 5 of each atomization metal nozzle 4, manually operation or automatic sequence opens solenoid valve, realize the on-line rinsing to discharging tray 5.In addition, in abnormal cases, when the too high startup of temperature in equipment, spray irrigation system is opened automatically.
Power-supply system is divided into and equipment integral type and discrete two kinds.Power-supply system comprises multiple power pack 7, the corresponding power pack 7 of each discharging tray 5.
Being evenly distributed after entering low-temperature plasma equipment for making waste gas, ensureing treatment effect, waste gas being divided into multichannel and entering low-temperature plasma device interior flow passage components.In air inlet 1, air outlet 8 and shell 2, according to gas motion principle, arrange cloth wind flow guide system 3, make without eddy current, short stream, bias current in air channel, waste gas is evenly distributed to each discharging tray 5 region, is effectively purified under action of plasma.
Low-temperature plasma equipment to the operation principle that garbage transfer station foul gas purifies is:
In double-dielectric barrier discharge process, electronics obtains energy from electric field, by collision by Conversion of Energy be in contaminant molecule can or kinetic energy, these molecules obtaining energy are excited or ionization occur and form active group, oxygen simultaneously in air and moisture also can produce a large amount of hydrogen in statu nascendis, ozone and hydroxyl oxygen isoreactivity group under the effect of high energy electron, and the mutual collision rift of these active groups has just caused physics, the chemical reaction of series of complex.Form as can be seen from the active group of plasma, high chemically active particle is rich in plasma inside, as electronics, ion, free radical and excited state molecule etc.Polluter in waste gas and these active groups with higher-energy react, and are finally converted into CO
2and H
2o etc. are pollution-free material, thus reach the object of purifying exhaust air.
With H in garbage transfer station waste gas
