According to the invention, the process arrangement of parallel contact of a filter membrane plane and a liquid flow is employed, thereby a full opening channel structure which has the characteristics of non deflector, small resistance, little possibility of dirt accumulation on the surface of membrane; simultaneously, a positive pressure filtration process and a hard disc type membrane filtration module are used for specially-producing composite membrane with high strength wear resistance; therefore, a reliable effective filtering and recovery device with low cost is provided for solving the problems of grinding industrial drained slurry or treating viscous waste water.
Description
Technical field
the invention belongs to the wastewater treatment equipment technical field, particularly relate to a kind of membrane-way water treating device.
Background technology
current, advanced multi-line cutting machine is widely used in the thin silicon sheet cutting processing of the substrates such as integrated circuit, solar cell the sixth of the twelve Earthly Branches.It is to adopt grinding, the cooling mortar is comprised of carborundum, polyethylene glycol (PEG) etc., rubs continuously with silicon slice workpiece under the metal wire run up coordinates and completes the mill of wafer is cut.In cutting process, the HIGH-PURITY SILICON bits are constantly sneaked in the abrasive material mortar, have finally affected cutting usefulness and workpiece quality, now need to upgrade mortar.And approximately contain the silica flour of 33% carborundum, 35%PEG and 9% in waste mortar, for fear of environmental pollution, reclaim valuable raw material saving production cost, waste mortar must be recycled.At present, advanced method waste mortar recycled is: first to waste mortar add thinner → carry out Separation of Solid and Liquid obtain one-level parting liquid and one-level solid particle → one-level parting liquid through the deckle board isolated by filtration obtain the second-order separation liquid and secondary solid particle → the second-order separation liquid must three grades after microporous barrier, hollow fiber ultrafiltration membrane, ion-exchanger processing parting liquids → through Distillation recovery, obtain polyethylene glycol and can make the slops of thinner; In addition the I and II solid particle is reclaimed to carborundum through alkali, acid, washing.The key equipment of above-mentioned recovery polyethylene glycol is hollow fiber membrane ultrafiltration device, due to the mortar parting liquid that enters hollow fiber membrane ultrafiltration device, though divide through above-mentioned pre-processing device the larger solid particle of leaving away, but still there is the problem that solid content is high, viscosity is large, very easily wear and tear, stop up hollow-fibre membrane, and due to hollow-fibre membrane contaminated after easy cleaning not, therefore fault rate is high in process of production for existing hollow fiber membrane ultrafiltration device, service life is short, production efficiency is low, has seriously restricted effective recycling of mortar generated in silicon chip cutting.
summary of the invention
purpose of the present invention, be to be industrial grinding waste mortar, and the particularly recycling of silicon chip cutting grinding waste mortar provides that a kind of separative efficiency is high, long service life, membrane-filtering unit that operating cost is lower.
technical scheme of the present invention is: a kind of industrial grinding waste mortar molecular filter, comprise cylindrical shell, superpose and be installed on the ultrafiltration module formed on the water purification outlet pipe of center continuously by locking plate by some filter membrane components, the described cylindrical shell side's of being body or cuboid, the center water purification outlet pipe of ultrafiltration module flatly is installed in cylindrical shell, the one end is fixed on cylinder inboard wall, the other end passes cylindrical shell, is connected with respectively feed liquor adapter and fluid on cylindrical shell bottom surface, end face and takes over.
as preferably, described cylindrical shell is closed pressure container, and operating pressure is 2～5kg/cm
2
.
as preferably, described membrane filtration element is to be overlapped into one successively by primary diaphragm, the first filter screen, dividing plate, the second filter screen and secondary diaphragm, its surrounding is edge sealing, centre offers the interlocking hole and forms, and it and ring groove shape locking plate form hard disk plate type ultrafiltration membrane locking component.
as preferably, described primary diaphragm and secondary diaphragm all are coated with on the PET nonwoven by Kynoar and polytetrafluoroethylene (PTFE) composite material and make.
as preferably, cylinder body bottom is horizontally installed with some row's cleaning hoses, is evenly equipped with gas distribution or liquid distributing hole on cleaning hose.
the invention has the beneficial effects as follows: this molecular filter has changed domestic and international traditional filter membrane plane and the vertical technology arrangement contacted of liquid stream, and creatively adopted the capable technology arrangement contacted of filter membrane plane and liquid levelling, thereby realized the surperficial full open model flow passage structure that is difficult for long-pending attached dirt of, film little without deflector, resistance; This ultrafilter adopts the pressure positive press filtration simultaneously, has greatly strengthened the motive force of membrane filtration; In addition, adopted the hard-disc type membrane filtration assembly of the applicant's development, particularly special by Kynoar with the painting of polytetrafluoroethylene (PTFE) composite material on the PET nonwoven and the high-strength abrasion-proof compound film sheet of making reaches more than 6 years ultrafiltration module service life; Also in ultrafilter to diaphragm arrangement the air-water mixture device, remove off and on the dirt stick to membrane surface, can keep for a long time membrane surface clean; Thereby, for solving the difficult problem of industrial grinding waste mortar or toughness wastewater treatment, successfully provide a kind of effectively reliable and low filtering recovering device of processing cost.
