Description
Technical field
The present invention relates to the sewage treatment equipment containing organic solvent, specifically containing organic solvent method of wastewater treatment and device thereof.
Background technology
Wet spinning, hollow-fibre membrane manufacture process all can produce substantial amounts of containing dimethyl acetylamide (DMAc) or the organic wastewater of dimethylformamide (DMF).Directly on the one hand the discharge waste water containing organic solvent cause environmental pollution, still further aspect to also result in the wasting of resources.
From the waste water containing organic solvent, reclaim organic solvent be probably the most economical technological means solving the contaminated wastewater containing organic solvent.
DMAc or DMF boiling point is higher than the boiling point of water, when DMAc or DMF is about 20% in waste water, the way of distillation is taked to process these waste water reclamation organic solvents, owing to water evaporation latent heat is big, therefore, utilize the way of distillation to reclaim organic solvent and there is the defect that energy resource consumption is big.
Summary of the invention
Present invention aims to the problem and shortage of above-mentioned existence, there is provided one utilize hydrophobicity adsorbent equipment and heat pump class dehydrating unit associated working, with utilize conventional distillation reclaim organic solvent relative energy-saving more than 70% containing organic solvent method of wastewater treatment and device thereof.
The above-mentioned purpose of the present invention is to be achieved by the following technical programs:
Containing organic solvent method of wastewater treatment, utilize and be dried the waste water that gas stripping contains organic solvent, water and organic solvent is made to exist in the form of a vapor, it is then passed through hydrophobic adsorption device absorbing organic solvent, remove moisture through dehydrating unit again, utilize blower fan to make gas circulate between said apparatus.
Containing organic solvent wastewater treatment equipment, including packed tower, dehydrating unit, adsorbent equipment and air circulation duct；
Packed tower is made up of spray liquid distributor, filler, spray liquid pool and feeding spraying pump, spray liquid pool and wastewater outlet is located at bottom packed tower, packed tower bottom is provided with dry gas feed, packing area it is provided with in the middle part of packed tower, packing area is built with filler, top, packing area is equipped with spray liquid distributor, packed tower top is provided with gas outlet, and wastewater outlet pipeline is by feeding spraying pump and water-cooled condenser connection spray liquid distributor.
Dehydrating unit is made up of refrigeration compressor, air-cooled condenser, water-cooled condenser, refrigeration expansion valve and refrigerating evaporator, and is connected into cooling cycle system.
Air circulation duct is sequentially connected with packed tower gas outlet, adsorbent equipment, refrigerating evaporator, air-cooled condenser, circulating fan, packed tower are dried gas feed.
Between water-cooled condenser and spray liquid distributor, pipeline is provided with the loop being back to spray liquid pool, is respectively equipped with Water flow adjusting valve door between water-cooled condenser and spray liquid distributor on pipeline and loop.Water flow adjusting valve door, its function is exactly the discharge ratio that regulation is delivered to spray liquid distributor and is returned directly to spray liquid pool.
Hydrophobic adsorption device can optionally absorbing organic solvent from air.Adsorbent equipment can be to utilize hydrophobic molecular to sieve the molecular sieve concentration runner that is fabricated by, or utilizes the fixed adsorbent bed that the molecular sieve of hydrophobic is fabricated by.After adsorbent equipment adsorbs a number of organic solvent, by heating, organic solvent can be made to regenerate from adsorbent equipment, and the organic solvent contained in regeneration air can realize condensation by cooling and reclaim.
The cold-producing medium discharged from refrigeration compressor first passes through after air-cooled condenser cools down again through water-cooled condenser cooling.The cooling medium of cooling condenser is exactly to need the waste water containing organic solvent to be processed, and the function of water-cooled condenser is to make cold-producing medium also make while cooling down to heat by the waste water containing organic solvent to be processed.
Feeding spraying pump has two functions, one of function makes the water in spray liquid pool make refrigeration system cool down through water-cooled condenser exactly, and another one function is exactly to make to need the waste water containing organic solvent to be processed to be uniformly distributed in filler from spray liquid distributor in spray liquid pool.
Water section through water-cooled condenser sprays on the filler of packed tower through spray liquid distributor as spray liquid, and part directly sends spray liquid pool back to.
The function of circulating fan is exactly to circulate air through packed tower, the adsorbent equipment of hydrophobic, the refrigerating evaporator of refrigeration system and the air-cooled condenser of refrigeration system, finally sends packed tower back to.
The present invention is designed by above-mentioned structure, dry gas is utilized to carry the waste water containing organic solvent by packed tower equivalent, water and organic solvent is made to exist in the form of a vapor, recycling hydrophobicity adsorbent equipment and heat pump class dehydrating unit associated working, first with hydrophobic adsorption device absorbing organic solvent, then utilize dehydrating unit to remove moisture, reclaim organic solvent relative energy-saving more than 70% with utilizing conventional distillation.
