Description
Technical field
The utility model relates to the sewage treatment equipment containing organic solvent, specifically containing organic solvent wastewater treatment equipment.
Background technology
A large amount of organic waste water containing N,N-DIMETHYLACETAMIDE (DMAc) or dimethyl formamide (DMF) all can be produced in wet-spinning, hollow-fibre membrane manufacturing processed.Direct discharge causes environmental pollution on the one hand containing the waste water of organic solvent, also causes the wasting of resources on the one hand in addition.
The most economical technique means that organic solvent may be the contaminated wastewater solved containing organic solvent is reclaimed from the waste water containing organic solvent.
DMAc or DMF boiling point is higher than the boiling point of water, when DMAc or DMF in waste water is about 20% time, take these waste water reclamation organic solvents of distillation method process, because water vaporization heat is large, therefore, utilize distillation method to reclaim organic solvent and there is the large defect of energy consumption.
Summary of the invention
The purpose of this utility model is for above-mentioned Problems existing and deficiency, there is provided one to utilize hydrophobic nature adsorption unit and the associated working of heat pump class dehydrating unit, with utilize Conventional espresso method reclaim organic solvent relative energy-saving more than 70% containing organic solvent wastewater treatment equipment.
Above-mentioned purpose of the present utility model is achieved by the following technical programs:
Containing organic solvent wastewater treatment equipment, comprise packing tower, dehydrating unit, adsorption unit and air circulation duct;
Packing tower is made up of spray liquid sparger, filler, spray liquid pool and feeding spraying pump, spray liquid pool and wastewater outlet is located at bottom packing tower, packing tower bottom is provided with dry gas import, packing area is provided with in the middle part of packing tower, packing area is built with filler, spray liquid sparger is equipped with on top, packing area, packing tower top is provided with gas outlet, and wastewater outlet pipeline is communicated with spray liquid sparger by feeding spraying pump and water-cooled condenser.
Dehydrating unit is made up of refrigeration compressor, air-cooled condenser, water-cooled condenser, refrigeration expansion valve and refrigerating evaporator, and parallel-series becomes cooling cycle system.
Air circulation duct is bonding pad tower gas outlet, adsorption unit, refrigerating evaporator, air-cooled condenser, recirculation blower, the import of packing tower dry gas successively.
Between water-cooled condenser and spray liquid sparger, pipeline is provided with the loop being back to and spraying liquid pool, between water-cooled condenser and spray liquid sparger, pipeline and loop is respectively equipped with Water flow adjusting valve door.Water flow adjusting valve door, its function is exactly regulate deliver to spray liquid sparger and directly get back to the discharge ratio spraying liquid pool.
Hydrophobic adsorption device can optionally absorbing organic solvent from air.Adsorption unit can be the molecular sieve concentration runner utilizing hydrophobic molecular sieve series to make, or utilizes the fixed adsorption bed of molecular sieve manufacture of hydrophobic.After the organic solvent of adsorption device adsorbs some amount, by heating, organic solvent can be made to regenerate from adsorption unit, and the organic solvent contained in regeneration air can realize condensation recovery by cooling.
The refrigeration agent of discharging from refrigeration compressor first cools through water-cooled condenser after air-cooled condenser cooling again.The heat-eliminating medium of cooler condenser is exactly need the waste water containing organic solvent to be processed, and the function of water-cooled condenser also makes the while of making refrigerant cools to need the waste water containing organic solvent to be processed to heat.
Feeding spraying pump has two functions, one of function is exactly make the water in spray liquid pool through water-cooled condenser, refrigeration system be cooled, and another one function is exactly make to need the waste water containing organic solvent to be processed to be distributed to equably filler from spray liquid sparger in spray liquid pool.
Water section through water-cooled condenser sprays on the filler of packing tower through spray liquid sparger as spray liquid, and part directly sends spray liquid pool back to.
The function of recirculation blower is exactly make air cycle through the air-cooled condenser of the adsorption unit of packing tower, hydrophobic, the refrigerating evaporator of refrigeration system and refrigeration system, finally sends packing tower back to.
The utility model is by above-mentioned structure design, dry gas is utilized to carry the waste water containing organic solvent by packing tower equivalent, water and organic solvent are existed in the form of a vapor, recycling hydrophobic nature adsorption unit and the associated working of heat pump class dehydrating unit, first utilize hydrophobic adsorption device absorbing organic solvent, then utilizing dehydrating unit to remove moisture, reclaiming organic solvent relative energy-saving more than 70% with utilizing Conventional espresso method.
Below in conjunction with accompanying drawing, the utility model is further described.
