Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
The oil curtain purifying column suitable for waste gas absorption adsorption plant involved by this case, in structure, as shown in figure 1, bag
Include tower body 5, base and aiutage 11.
The bottom of tower body 5 is connected with base, and the top of tower body 5 is connected with aiutage 11.
The lower end of tower body 5 is provided with exhaust collection mouth 6 and additive import.In the present embodiment, additive import includes adding
Hydraulic fluid port 7 and tap water inlets 8, and exhaust collection mouth 6 is arranged on the upper end of additive import.Exhaust collection mouth 6 is in tower body 5
Exit towards under, one cause to greatest extent with additive import enter composition contact.
Activated carbon adsorption layer 1, gas-liquid contact layer and some hollow clapboards 12 are disposed with inside tower body 5 from top to bottom.
Internally in structure, one end of each hollow clapboard 12 is connected with the side wall of tower body 5, and the other end is free end, with tower body 5
Side wall between be provided with space.Neighbouring hollow clapboard 12 and the link position of the side wall of tower body 5 mutually deviate from, that is, cause
All hollow clapboards 12 will be divided into continuous S-shaped passage inside tower body 5, in order to waste gas, the distance through stream is longer in tower body 5,
Time is more long, improves the efficiency for absorbing processing.
Base is connected with circulating pump 10, and circulating pump 10 is connected with the cavity of the superiors hollow clapboard 12.Base is provided with
Waste gas tower liquid sewage draining exit, the absorbing liquid flowed down along hollow clapboard 12 can flow to tower bottom after multistage blended absorbent in order,
And by being fully absorbed from top to bottom with the VOCs waste gas in waste gas on more than 10 hollow clapboard 12 for being extracted into the superiors of circulating pump
Absorption.In use, in the cavity of hollow clapboard 12 by the way that oil-water mixture to be extracted into the superiors so that the dividing plate of lower section is formed
Blended absorbent adsorption liquid is covered with profit curtain 3 and profit curtain 4, the efficiency handled so as to the absorption improved to VOCs in waste gas.
The junction of hollow clapboard 12 and oil mixing with water curtain is dead slot, in order to which oil can pass through from cavity, and it is suitable
Flow to sharply on lower floor's hollow clapboard 12, in favor of forming oil mixing with water curtain again.
The present apparatus is for paint tail gas, VOCs tail gas absorptions, absorption complete set of equipments, suitable for the organic tail gas of various concentration
Absorption processing, compared to active carbon adsorption equipment on the market at present, have treatment effect is stable, sorbing material replacing construction is long,
The advantages that organic matter adsorption efficiency is high, recyclable recycling, the scope of application is wider.
Various VOCs gases have certain solubility in certain solvent naphtha liquid, when VOCs gases and oily liq connect
When touching, untill amount that the material in VOCs gases is dissolved in solvent naphtha liquid progressively increases to saturation.Absorb the absorption after VOCs
Agent can pass through rectifying recovery liquefied petroleum gas product, and absorbent can be recycled after regeneration.
It is different according to discharge operating mode according to VOCs tail gas, the absorption of normal temperature oil can be divided into and low-temperature oil absorbs absorbing process.
The present apparatus has same treatment effect to NMHC processing.Operation a period of time can pass through grease trap according to test data
Releasing solvent naphtha is recycled or incineration disposal.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
