Description
Technical field
The present invention relates to waste gas purification fields, and in particular to a kind of process flow of ion cleaning exhaust gas.
Background technique
Ion cleaning is owned by France in advanced oxidation processes.Can effectively remove volatile organic matter (TVOC) in air, bacterium,
The harmful substances such as pellet, sulphur compound.Its distinguishing feature is using hydroxyl radical free radical as primary oxidizers and organic matter
It reacts, the organic free radical generated in reaction can continue to participate in the chain reaction of H, or by generating organic peroxy
Further occurrence oxidative decomposition is directly degraded to final product CO2 and H2O after object free radical, to reach oxygenolysis
The purpose of organic matter, specifically, the oxygen molecule in gas receives one surely when passing through ion Oxygen Generator at normal temperature
The collision of the electronics of amount makes neutral molecule lose electronics and becomes the basic ion of anode, and the electronics discharged moment and it is another in
Property molecule combine, form the basic ion of cathode, the oxonium ion with positive and negative charge respectively adsorbs 10-20 molecule formation cluster ion.
Because of the catalytic action of hydrogen oxide, OOH, and generate O2、O2-、O2+、·OH、·HO2, the oxygen cluster aggregation such as O, O, have extremely strong
Oxidability, oxidability is 1000 times of oxygen, the oxonium ion group of these high concentrations of generation rapidly with it is various it is inorganic,
Organic pollutant gas (VOC) molecular collision activates contaminant gases molecule, and can open the chemical chain of contaminant gases molecule
It is directly destroyed, furthermore the oxygen molecule in energetic ion oxygen activation gas generates secondary ion oxygen group, with contaminant gases point
A series of redox reactions occur for son, and gas pollutant is resolved into carbon dioxide and water；To sulfide, benzene class, aromatic hydrocarbon
Class equally has decomposition.
In the prior art, often focus on the improvement of ion purifier and ignore the preposition and postpositive disposal of ion cleaning method,
Ion cleaning method, which can not be increased substantially, volatile organic matter (TVOC), bacterium, pellet, sulphur compound etc.
The elimination efficiency of evil substance.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of process flows of ion cleaning exhaust gas, by ion
Preposition and postpositive disposal is added on the basis of the method for purification, improves the process flow of ion cleaning exhaust gas, effectively increasing in exhaust gas has
The removal rate of evil substance.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs:
A kind of process flow of ion cleaning exhaust gas, comprising the following steps:
S1, there is the bottom of spray column to enter equipment the exhaust gas, exhaust gas from bottom to top passes through spray tower packing, and from top to bottom
Spray liquid form convection current, complete mass transport process, exhaust gas forms solution after spray liquid absorbs and falls into the sink of spray column bottom,
Exhaust gas after coagulation is discharged after the dehydration of device demisting；
S2, the exhaust gas after coagulation is passed through to the gas gathering systems of ionic decontamination devices, by air filter into
Enter ion generator, then the exhaust gas after two stage treatment is discharged by exhaust fan；
S3, the exhaust gas after two stage treatment is passed through deep oxidation tower by air-introduced machine, the exhaust gas after two stage treatment is passing through depth
It is discharged after fills unit in degree oxidizing tower by exhaust tube.
Preferably, S1Described in spray tower packing be polypropylene plastics polyhedron empty ball.
Preferably, S1Described in spray liquid be clear water spray liquid, in alkalinity soda lye, liquor natrii hypochloritis, salt
Any one in acid solution.
Preferably, S2Described in air filter filtering Deng Ji≤F5, Ya power Sun Shi≤5mmH of filtering material2O。
Preferably, S2Described in ionic decontamination devices the temperature classification of insulating materials be F grades.
Preferably, S3Described in fills unit be modified filler.
(3) beneficial effect
The present invention provides a kind of process flows of ion cleaning exhaust gas, have the advantages that
Firstly, the preposition processing of spray column and deep oxidation tower postpositive disposal, solution are added on the basis of ion cleaning method
Certainly in gas ions oxidation reactor, organic matter is broken down into debris particles coming, and part of oxygen is also under the bombardment of high energy electron
Composition is formed, since the residence time is extremely short in plasma reactor for gas, the debris particles coming of generation causes to react insufficient etc.
Problem,
Secondly, deodorization purification is carried out to exhaust gas using ion purifier, it is no any to easily cause or may cause secondary pollution
Material or chemical agent, without waste water or other any secondary pollutions after processing, and within the scope of all specified deodorization spaces
Deodorization reaches state specified standards.Gas discharge meets odorant pollutant factory circle standard value second level in national standard after deodorization.
Finally, deep oxidation tower uses modified filler for packed column, debris particles coming can be effectively adsorbed, and promotes to be adsorbed on to fill out
Expect that oxidation reaction occurs for these compositions on tower.Since the packed tower is not intended to absorption organic matter, and always there are equal compositions
In the presence of, therefore, even if packed tower has adsorbed a small amount of organic matter, as the presence of the oxidation reactions such as ozone, so that packed tower
Always it is in unsaturated state, i.e., no replacement is required for the packed tower of this system use, can be used for a long time.
