Description
Technical field
The present invention relates to exhaust-gas treatment fields, more particularly to a kind of contactless stench gas with foreign flavor processing method and dress
It sets.
Background technique
Higher and higher to environmental requirement with the raising of Living consumption and the change of philosophy of life, odor pollution is
Had become a serious society and environmental problem.Odor pollution mostlys come from factory, foul gas complicated component and
It is big to monitor difficulty.Common foul gas can be divided mainly into 5 classes: nitrogenous compound, sulfur-containing compound, halogenated hydrocarbons, hydro carbons, oxygen-containing
Organic matter.Conventional foul gas processing method has washing absorption method, biological treatment, photochemical catalytic oxidation, burning, active carbon to inhale
Attached, plasma method etc..
(1) washing absorption method mainly reacts using water or solution dissolution foul gas and with foul smell molecule, but
It is that many foul gas are insoluble in water or solution, deodorizing effect difference and equipment maintenance cost height, generates waste water or solid waste etc. two
Secondary pollution.
(2) biological treatment is mainly that microbial physiology metabolic activity converts odorous gas.Foul gas is as micro- life
The nutriment of object.The disadvantage is that microorganism needs first to be cultivated, temperature is bigger to microbiological effect and takes up a large area.
(3) photochemical catalytic oxidation is irradiated by the ultraviolet light of specific wavelength, and activated catalyst generates electron hole pair, then
Catalyst reacts with water, oxygen molecule, generates hydroxyl free radical, foul gas is then decomposed, to reach the mesh of deodorization
's.But photochemical catalytic oxidation, catalyst is easy poisoning and catalyst needs to be replaced frequently, and causes secondary pollution.
(4) burn is that foul gas and fuel gas are sufficiently mixed realization completely burned.But it is suitable for handling high concentration
The combustible gas of small tolerance.But high equipment cost and equipment are easy to be corroded and are lost big, take up a large area, fuel gas disappears
Consumption is big, and O&M is costly.
(5) activated carbon adsorption is to make foul gas be transferred to solid phase from gas phase using the adsorption function of active carbon to remove to reach
Smelly purpose.The disadvantage is that adsorbent consumption is big and difficult for regeneration, it is desirable that exhaust-gas treatment temperature cannot be too high, and the solid waste of generation needs
It is handled again.
(6) plasma method is to generate ion, dielectric barrier discharge process to main reactor using ionic reaction gatherer
In, it is generated inside plasma and is rich in high chemically active particle, such as electronics, ion, free radical and excited state molecule.It is useless
Polluter and these active groups with higher-energy in gas react, and are eventually converted into CO2And H2The substances such as O, from
And achieve the purpose that purify exhaust gas.But inflammable and explosive gas is handled in the presence of risk is fired, electric discharge field action range is small, in height
Purification efficiency is low in the case of flow velocity, Wind Volume.
Summary of the invention
The present invention provides a kind of contactless stench gas with foreign flavor processing method and processing devices, are removed using non-direct contact type
It is smelly, avoid foul gas and directly contacted with equipment, can effectively increase the service life of equipment, reduce equipment depreciation rate with
The proportion of goods damageds, equipment is easy to operate, the later period, reaction was fast without too many management, equipment starting, stop it is very rapid, with with opening.
A kind of contactless stench gas with foreign flavor processing method, specifically: the air being sent by fresh-air fan is through filter
After going chalk dust removing and heating and dehumidification device to dehumidify, dry cleaned air is formed, is then drained into active oxygen atom reactor, activity
Oxygen atom reactor mixes the hydroxyl radical free radical of generation with active oxygen atom injection waste gas header with exhaust gas, in waste gas header
Deodorization purification smell removal is carried out, exhaust gas can discharge after processing.
A kind of contactless stench malodorous gas processing device, fresh-air fan, filter including successively piping connection plus
Hot dehumidifier, active oxygen atom reactor；The outlet of the active oxygen atom reactor is passed through waste gas header；The fresh-air fan
For air to be sent into filter；The filter is used to remove the dust in air；The heating and dehumidification device is used for will be empty
Gas heats to reduce the humidity of air；The active oxygen atom reactor is for generating hydroxyl radical free radical and active oxygen atom.
The filter is made using metal outer frame and active carbon filtering layer or filter cotton.
The heating and dehumidification device heats air using electric heating.
It is additionally provided with diffuser in the junction with active oxygen atom reactor in the waste gas header, for making active oxygen
Atom is further mixed with exhaust gas.
Advantages of the present invention: a kind of contactless stench gas with foreign flavor processing method and processing device of the invention, use are non-straight
Contact deodorization is connect, treatment process occurs in waste gas header, avoids foul gas and directly contact with equipment, can be effectively
Increase the service life of equipment, reduces equipment depreciation rate and the proportion of goods damageds；Device is easy to operate, the later period, reaction was fast without too many management,
Equipment starting, stop it is very rapid, with with opening；Active oxygen atom reactor passes through the H contained in ultraviolet light air2O
With O2, the extremely strong hydroxyl radical free radical of oxidisability and active oxygen atom are generated, catalyst is not used, it is without secondary pollution.
