Electrical tar precipitator, corona plasma common ground are to utilize the most uneven high-voltage dc, are formed Corona discharge, produces plasma, a large amount of electronics wherein comprised and the negative ions work in electric-force gradient Under with, and the particulate pollutant generation inelastic collision in air, thus attachment is on the particles, makes Become charged particle, to dust collecting electrode motion and then by collected by dust collecting electrode under the effect of electric field, thus Can effectively remove the particulate pollutant in air.
Its processing procedure divides three phases:
1) e+M (contaminant molecule) → M-
2)M-+ SP (solid particle) → (SPM)-
3)(SPM)-→ (being deposited in dust collecting electrode)
Corona discharge can produce nonequilibrium state low temperature plasma at certain space, can be used to purify air In harmful gas.Its catalytic purification mechanism includes two aspects:
1) during producing plasma, the high instantaneous energy that high-frequency discharge produces, opening some has The chemical bond of evil gas molecule so that it is resolve into monatomic or harmless molecule.
2) plasma contains substantial amounts of high energy electron, ion, excited state particle and there is Strong oxdiative Property free radical, the average energy of these active particles is about 5~20eV, near higher than general gas flow molecule Bond energy, they and harmful gas molecule occur to collide frequently, and the chemical bond opening gas molecule generates Monoatomic molecules or harmless molecule.A large amount of OH, the HO simultaneously produced2, free radical and the oxidation such as O Property extremely strong ozone be followed by evil gas molecule generation chemical reaction and generate harmless products.
The harmful gas produced during domestic garbage pyrolysis mainly has CO, NOx, SO2, HCl, this programme is just The harmful gas produced when being this catalytic purification mechanism utilizing plasma to purify refuse pyrolysis.

It is to be composited by two technology that electrical tar precipitator, corona plasma purify exhaust device, application It is an innovation that refuse at house refuse low temperature pyrogenation processes.
Electrical tar precipitator operation principle is applying high voltage direct current between plain conductor and metal pipe-wall, with dimension Hold the electric field that be enough to make gas produce ionization, make to be formed between anode and cathode corona zone.By electric field theory, just Ionic adsorption is in electronegative corona discharge electrode, anion is adsorbed in the receiving electrode of positively charged, all is ionized The whole space that negative ions is each filled with between corona discharge electrode and receiving electrode.When giving up containing impurity such as tar droplets When gas is by this electric field, adsorb the impurity of anion and electronics under the effect of electric field Coulomb force, mobile After receiving electrode, discharge institute electrically charged, and be adsorbed on receiving electrode, thus reach to purify the purpose of waste gas, Commonly referred to charged phenomenon.When the impurity level being adsorbed on receiving electrode increases to more than its adhesive force, meeting Automatically to dirty time, discharge bottom electrical tar precipitator.
It is to utilize Pulsed corona discharge that corona plasma purifies the principle of waste gas, makes gas ionization, So that exhaust gas particle is charged, then move to collecting polar plate under the effect of electric field force, charged Grain loses electric charge after contacting with collecting plate, becomes neutral and is deposited on collecting polar plate, thus reaches to purify The purpose of waste gas.Can produce during gas ionization simultaneously substantial amounts of high energy electron, ion, excited state particle and Having the free radical of strong oxidizing property, the average energy of these active particles is higher than the bond energy of gas molecule, it And harmful gas molecule occur collide frequently, open gas molecule chemical bond generate monoatomic molecules With innocuous gas molecule, a large amount of OH, the HO the most also produced2, free radical and the oxidisability pole such as O Strong ozone is followed by evil gas molecule generation chemical reaction and generates harmless products.
Its principle of the common ground of two technology is all corona discharge.The binding site of two technology is that corona is put Power supply selected during electricity: " the soft voltage-stabilizing power supply of critical pulse " or " pulse high-voltage direct current power supply ";Select suitable The corona discharge electrode closed, one is to need secondary electron yield (δ m) big;Two is to need reliable corrosion resistance With chemistry, physical stability.Therefore, tungsten is best suitable for making corona discharge electrode (δ m 1.4), rustless steel (δ m 1.24) Secondly.
Waste gas, through cloth air chamber, enters the space between honeycomb receiving electrode and corona discharge electrode, at DC Electric Field Under, gas is ionized, so that exhaust gas particle is electrically charged, then sinks to honeycomb under the effect of electric field force Shallow lake Ghandler motion moves, and loses electric charge after contacting with honeycomb receiving electrode, becomes neutral and is deposited on honeycomb receiving electrode, Thus reach to purify the purpose of waste gas.Along with the increase of adsorbance, the material of absorption can freely fall, nothing Honeycomb receiving electrode need to be cleared up.
Meanwhile, substantial amounts of high energy electron, ion, excited state particle can be produced during gas ionization and have strong The free radical of oxidisability, the average energy of these active particles higher than the bond energy of gas molecule, they and have Evil gas molecule occurs to collide frequently, and the chemical bond opening gas molecule generates monoatomic molecules and harmless Gas molecule, a large amount of OH, the HO the most also produced2, the free radical such as O and extremely strong smelly of oxidisability Oxygen is followed by evil gas molecule generation chemical reaction and generates harmless products.
The beneficial effect of exhaust-gas treatment: one is by (weighing with steam, tar, flying dust in pyrolysis garbage Metal), the aerosol class material that merges such as waste gas effectively traps;Two is by the oxidation in waste gas Carbon (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), Hydrocarbon, aromatic hydrocarbon etc. purifies.
Two technology are applied in the process of domestic garbage pyrolysis waste gas, revolutionize refuse pyrolysis waste gas row Put mode, smokeless, free from extraneous odour in line (zero-emission).

Ash layering
The lime-ash produced after carburization zone semicoke carbonization is in ash layering ashing and cooling.
Carburization zone
Semicoke (garbage carbon), in carburization zone carbonization heat release, produces high-temperature flue gas and lime-ash.Carbonization release Heat energy is absorbed by energy-accumulation material and stores, and when adding house refuse in stove, domestic garbage pyrolysis is absorbed Heat provided by carburization zone and energy storage material heat release, the thermal discharge of carburization zone is more than the warm increasing upper rubbish Desorbing heat, pyrolytic reaction just can go on.It is thus desirable to ensure the carburizing temperature of carburization zone.At carbon The temperature recorded, equipped with temperature transmitter, is input to automatically control by change layer with analog quantity (0-24mA) signal In systematic microprocessor processed, the temperature being controlled carburization zone by the analog quantity output signals of microprocessor is regulated The state of valve, controls the temperature of carburization zone.The temperature of carburization zone controls at 450 DEG C~500 DEG C.
Pyrolytic layer
Rubbish, after dehydration, continues heat absorption, and when temperature is more than 200 DEG C, organic matter in garbage divides The side chains such as methyl in son, ethyl start fracture, slough carbon and hydrogen respectively, generate methane, hydrogen and The micro-molecular gas such as other Hydrocarbon.Along with the further rising of temperature, take off the Organic substance of side chain Main chain rupture, generate many small-molecule substances.The pyrolysis of rubbish is not necessarily to certain time Sequence is carried out, and many reactions all intersections are carried out.The produced little molecule of pyrolysis is through condensation reaction again It is reassembled into the Organic substance of macromole, and the Organic substance of these macromole may also pass through cracking and again becomes For the Organic substance of little molecule, so the pyrolysis of rubbish is extremely complex physics, a chemical process.?
