Description
Technical field
This utility model relates to water treatment field, is specifically related to a kind of place based on stripping with MVR group technology
The system of reason wastewater from chemical industry.
Background technology
The mode that China's major part chemical enterprise generally uses in terms of waste water process at present is that waste water is carried out letter
Enter biochemistry pool after single pretreatment and carry out biochemical treatment again.Although biochemical process is the industry that Technical comparing is ripe
Change method, and processing cost is relatively low, but owing to wastewater from chemical industry toxicity is high and biodegradable containing being much difficult to
Organic substance, thus adopt process wastewater from chemical industry in this way and be often difficult to obtain preferable effect.And traditional thing
Physicochemical method is at the aspect Shortcomings such as removal wastewater toxicity and the biodegradability improving waste water, some thing
Logos preconditioning technique can not thoroughly reduce toxic component, thus causes transfer and the secondary pollution etc. polluted.
Therefore the pretreatment of wastewater from chemical industry must be strengthened, by the pollutant of high for toxicity, difficult for biological degradation at pretreatment stage
It is completely separated or is converted into degradable material, the most again through biochemical treatment to reach preferable treatment effect.
In principle, all of COD is produced by volatile or nonvolatile material.For volatilization
Property material, they can be separated by steam stripped process with water, for nonvolatile material, utilizes distillation side
Method, can reach to purify the purpose of water.
In stripping process, allow waste water directly contact with water vapour, make the volatility poisonous and harmful substance in waste water
It is diffused in gas phase by a certain percentage, thus reaches to separate the purpose of pollutant from waste water.The base of vaporizing extract process
Present principles is identical with blow-off method, and the medium simply used is different, and stripping is by mean of water steam medium and realizes
's.
The technique of vaporizing extract process separation pollutant regards the character of pollutant and different, typically can be summarized as following two:
1. simple distillation: for volatile material miscible with water, utilize its under the conditions of vapor liquid equilibrium,
Concentration in the gas phase is more than this characteristic of concentration in the liquid phase.Pass through steam direct heating so that it is at boiling point
At (a certain temperature between water and volatile matter two boiling point), it is enriched in gas phase by a certain percentage.
2. steam distillation: for immiscible with water or insoluble,practically volatile contaminant, utilize mixed liquor
Boiling point less than two these characteristics of component boiling point, high boiling point volatile matter can be separated at a lower temperature and be taken off
Removing, these volatile organic matters include but not limited to:
Alcohols: methanol, ethanol, propanol, butanol etc.；
Ketone: butanone, acetone, methyl isopropyl ketone etc.；
Aromatic hydrocarbons: benzene, toluene, dimethylbenzene, ethylbenzene, Ethenylbenzene etc.；
Aliphatic hydrocarbon: hexamethylene, hexane, pentane etc.；
Esters: Ethyl formate, ethyl acetate, ethyl propionate etc.；
Chloride: bismethane, chloroform, carbon tetrachloride, dichloroethylene etc.；
Other: acetaldehyde, second cyanogen, amine, ether etc..
After stripping, the above-mentioned Organic substance of the overwhelming majority will be separated, and reduce toxicity and COD
Purpose.
MVR vaporizer be applied to widely food processing, concentration of juices, beverage production, Dairy Production,
A kind of evaporation concentration equipment in the fields such as the process of chemical industry, pharmaceutical industry, waste water, environment-friendly engineering.From steaming
Sending out the compression through compressor of the device indirect steam out, pressure and temperature increases, and heat content increases therewith,
The heating chamber being sent to vaporizer i.e. gives birth to steam use as heating steam source, makes feed liquid maintain evaporating state,
And adding after vapours transfers heat to material, itself is condensed into water.So, steam to be discarded is just
It is fully utilized, has reclaimed latent heat, improve again the thermal efficiency.Its work process is low-grade steaming
Vapour compresses through compressor, and temperature, pressure improve, and heat content increases, and condenses subsequently into heat exchanger, with fully
Utilize the latent heat of steam.In addition to start up, without raw steam in whole evaporation process.
After MVR distills, the nonvolatile organic and inorganic matter of the overwhelming majority will be separated, and reach
To the purpose reducing toxicity, salinity and COD further.
