Abstract
The invention provides a separating device of a ceramic membrane for waste liquid cycling filtration. The separating device comprises a multistage pump, a liquid storage tank, a ceramic membrane filter, a circulation pipeline, a clear liquid outlet, and a liquid storage tank feed inlet. The liquid storage tank, multistage pump, and ceramic membrane filter are sequentially connected through the circulation pipeline to form a circulation loop. The liquid storage tank feed inlet is arranged in the liquid storage tank. The clear liquid outlet is arranged in the ceramic membrane filter. A sewage outlet is arranged in the circulation pipeline between the ceramic membrane filter and the liquid storage tank. The ceramic membrane filter is provided with a ceramic membrane, the tube walls of the ceramic membrane are densely provided with micro pores, and the pore size of the micro pores is in a range of 50 to 80 nanometers. The device adopts a ceramic membrane to filter wastes; a circulation loop is utilized, the waste gas, waste solid, and waste liquid are repeatedly filtered, the clear liquid can be recycled and reused, the impurity liquid can be condensed repeatedly, and finally the condensed waste liquid is absorbed by diatomite.
Description
Technical field
The present invention relates to the waste liquid filtration art produced in separating metal powder oil-containing powder process, be specifically related to the ceramic membrane separation device filtered for waste liquid circulation.
Background technology
In waste liquid filtration art, existing technology is: absorption method, the precipitator method, neutralisation and diatomite handling method etc., major part is disposable, can not Reusability, the adsorption paper of such as absorption method, the medicament that neutralisation adopts and the material used such as diatomite process be all disposable can not Reusability, investment is large, scale is large, and floor space is large.Also handy special messenger keeps an eye on, and the waste liquid cost processing the generation of this production process is high.The clear liquid utilization ratio produced by the method disposed waste liquid at present is low, finally must discharge, affect environment.
Specifically can produce some waste liquids in separating metal powder oil-containing powder process, as scrapped scavenging solution, water surface has micro-oil slick, water solution of oil.If these liquid do not process, be only excluding of can not re-using aborning, just pollute the environment if drained, this is unallowed, but absorption method, the precipitator method, neutralisation and diatomite handling method etc. are inapplicable for this production process.
Summary of the invention
For this shortcoming, the present invention takes ceramic membrane filter mode, utilizes circulation loop, three wastes stillness of night after repeatedly filtering can be returned and produce recycling, returned again by the clear liquid filtering institute's output and continue to use, assorted liquid can concentrate repeatedly, finally concentrated waste liquid can be added diatomite adsorption.
For achieving the above object, the invention provides the ceramic membrane separation device filtered for waste liquid circulation, it comprises stage pump, container for storing liquid, purpose ceramic-film filter, circulation line, goes out clear liquid mouth, container for storing liquid opening for feed; Described container for storing liquid, stage pump, purpose ceramic-film filter connect into circulation loop by circulation line successively, container for storing liquid is provided with container for storing liquid opening for feed, purpose ceramic-film filter is provided with out clear liquid mouth, the circulation line between purpose ceramic-film filter and container for storing liquid arranges sewage draining exit.Described purpose ceramic-film filter is provided with ceramic membrane, and ceramic membrane tube wall gathers micropore.The hole of described micropore is in 50 ~ 80 nanometers.
Described ceramic membrane separation device is applied to the used wiping solution, the emulsion that produce in separating metal powder oil-containing powder process, the filtration of floating oil-water fluid.
Ceramic-film tube material adopts aluminium sesquioxide to be that raw material is formed with some strength shaped solids block by forming and sintering, this solid piece forms a lot of fine porosity from surface to inside, these fine porositys be interconnected formed a slice netted, liquid body is through these netted holes, the liquid body of small molecules can be filtered removing by these fine porositys, the liquid body of macromole is hindered, and is difficult to the object reaching filtration through these fine porositys.Not only its characteristic of this material of aluminium sesquioxide is, acidproof but also alkaline-resisting, and the liquid mainly aobvious neutrality handled by us.According to the feature having liquid, namely fluid molecule varies in size, select ceramic membrane hole be 50 to 80 nanometers as well.
Ceramic membrane tube wall gathers micropore, hole (also has the ceramic-film tube of other specification holes in 50 to 80 nanometers, only have the specification limit effect of statement good) under certain pressure effect, liquid is in film pipe or film pipe flows outside, small-molecule substance (or liquid) such as water is gone out through membranous wall seepage, macromole and long chain molecule (or solid) tunicle retain, thus reach the object of separation and purification liquid.Adopt ceramic membrane separation clean-out system waste liquid and micro-oil slick waste water and water solution of oil, the stillness of night of recovery can recycle.Accomplish the object without discharge or micro-discharge.Rear effect reused by the clear liquid of all recovery and former clear water is unchanged, and the liquid body after concentrated is no more than 1%, will be longer during use, and concentrated solution accounting example is less.
Beneficial effect of the present invention: the present invention is environmental protect effectively, accomplishes without discharge, or micro-discharge, improves huge liquid waste treatment system, reduces the consumption reducing water.Take up an area few, practicable unattended.By used scavenging solution by ceramic membrane filter, cleaner liquid can reclaim and reuse.The removing of water solution of oil and water surface oil film, can make water after treatment reuse, and reaches the object without discharge or micro-discharge.The present invention utilizes ceramic membrane to be namely acidproofly have alkaline-resisting aluminium sesquioxide material to make, the aperture of ceramic membrane can be selected, select suitable ceramic membrane aperture 50 to 80 nano level, facility compact, floor space is little, and can realize automated operation, keep an eye on without special messenger, cost is low, can Reusability, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1, stage pump, 2, container for storing liquid, 3, purpose ceramic-film filter, 4, circulation line, 5, go out clear liquid mouth, 6, sewage draining exit, 7, container for storing liquid opening for feed.
For the ceramic membrane separation device that waste liquid circulation filters, it comprises stage pump 1, container for storing liquid 2, purpose ceramic-film filter 3, circulation line 4, goes out clear liquid mouth 5, container for storing liquid opening for feed 7; Described container for storing liquid 2, stage pump 1, purpose ceramic-film filter 3 connect into circulation loop by circulation line 4 successively, container for storing liquid 2 is provided with container for storing liquid opening for feed 7, purpose ceramic-film filter 1 is provided with out clear liquid mouth 5, the circulation line between purpose ceramic-film filter 3 and container for storing liquid 2 is arranged sewage draining exit 6.Described purpose ceramic-film filter 3 is provided with ceramic membrane, and ceramic membrane tube wall gathers micropore.The hole of described micropore is in 50 ~ 80 nanometers.
