Description
Technical Field
The present invention belongs to the field of chemical solid-liquid mixture or solution separating technology. Can be widely used in the chemical application fields of chemical industry, pharmacy, environmental protection, papermaking, printing and dyeing, metallurgy and the like.
Background
Filtration is the operation of separating solids and other substances from liquids (or gases) by passing the liquids (or gases) in suspension (or heated gases containing the solids) through a medium under the action of an impetus or other external force, with the solids and other substances being trapped by the filtration medium. Is a very widely used unit operation. The existing technology of interception through a medium has the problems that the interception matters (commonly called filter cakes) block or obstruct the separated solvent or another one or more separated matters to pass through the medium, energy consumption is consumed, the separation efficiency is influenced, the operation is interrupted by cleaning the separated matters (filter cakes), and the working efficiency is seriously influenced. To overcome this drawback we have invented a separation method and apparatus for automatic flushing media which not only replaces the traditional filtration, but also uses the proper semipermeable membrane for low temperature concentration or desalination or purification of water.
Disclosure of Invention
We have thus achieved the object of the invention through a number of trial and error. First, we will not leave the trapped solid matter on the surface of the separation medium. To this end, we let the trapped large material be pushed by the forward fluid to leave the medium as a channel for the filtered small material.
The further explanation is as follows:
the pipeline filter is adopted, so that the trapped matters continuously move forward along the pipeline, and the filtered matters smoothly pass through the medium and freely move outside the medium. Thus, the resistance of the medium is reduced, and the separation can be performed continuously.
In order to keep the medium surface clean, the rotational flow body is preferably adopted to generate scouring force to continuously scour and clean the wall of the medium, so that the period of continuous operation is further prolonged.
The automatic flushing medium continuous separation method adopts the method that the rotor is driven by high-pressure fluid to automatically flush the surface of the filter medium, thereby realizing the improvement of the medium separation efficiency.
The automatic flushing medium continuous separation device comprises a fluid inlet, a cyclone body shaper, a separation medium, a shell, a separator outlet, a mother liquor circulation control valve, a mother liquor outlet control valve and the like, wherein the fluid inlet is inlaid at the front end of the shell, forms a mother liquor temporary storage space together with the inner surface of the separation medium, the mother liquor outlet and a related control valve, the cyclone body shaper is arranged in the separation medium, and the formed rotary fluid dynamically cleans the inner surface of the separation medium to form a mother liquor temporary storage space; an independent space for temporarily storing the separation matters is formed by the outer surface of the separation medium, the inner surface of the shell and the separation matter outlet.
The swirl body shaper is further provided with one or a plurality of small slits for releasing fluid so as to realize the selective cleaning of the blocking part. The rotor is driven by high-pressure liquid to automatically flush the surface of the separation medium, so that the medium separation efficiency is improved.
The fluid release slit is further made to be small, the far end opening is large, the near end opening is small, and the front end and the rear end of the whole flushing effect are uniform.
Drawings
Fig. 1 is a schematic structure diagram, 1, a fluid inlet, 2, a cyclone body shaper, 3, a separating medium, 4, a shell, 5, a separator outlet, 6, a mother liquor circulation control valve, 7 and a mother liquor outlet control valve.
As shown in the figure, after the fluid acquires kinetic energy from the pushing device, the fluid enters the fluid inlet 1 and then enters the cyclone body shaper 2, the fluid is released in small holes and/or small slits of the cyclone body shaper and acts on the separation medium, the reaction force pushes the cyclone body shaper 2 to transfer at high speed, the separation medium 3 is evenly washed, the mother solution of the washing medium circulates through the mother solution circulation control valve 6 and controls and stabilizes pressure, or enters the next processing unit through the mother solution outlet control valve 7, and a certain flow rate is controlled to keep a certain pressure, so that the separated matter is conveniently pushed to pass through the medium. After temporary storage of the separation medium 3 in the limited space of the housing 4, the separation medium is discharged from the separation medium outlet 5 or stored or passed into the next processing unit.
Detailed Description
Example 1
The scheme of the invention is applied to sea water desalination. The reverse osmosis membrane (OA) is fixed on a tubular filter bracket, a centrifugal water nozzle is arranged at the inlet, the outlet 1 is arranged outside the reverse osmosis membrane to be desalted water, the outlet 2 is arranged at the outlet of the reverse osmosis membrane tubular filter to be concentrated solution, and the reverse osmosis membrane tubular filter can be communicated with the inlet to circularly permeate until the concentration required by concentration is achieved.
The desalinated water from the outlet 1 can be subjected to front end rough filtration, and the service time of the device can be further prolonged by using the device.
Example 2
Concentrating the liquid medicine at low temperature. We generally concentrate the liquid medicine by heating and evaporating. Some thermosensitive drugs are not suitable and low temperature concentration using the present invention is the best option. The semipermeable membrane through which solvent molecules can pass is made into a cylindrical filter, and water flow is controlled to enter along the tangential direction of the semipermeable membrane so as to wash the surface of the semipermeable membrane through the water flow, thereby maintaining and improving the permeability of the semipermeable membrane.
Example 3
And (5) separating the medicines. As above. The mixed liquid of the medicines to be separated is regulated to PH, a solvent or a precipitant is added, then the liquid medicine is pumped into a sand filter stick for filtration, and then the filter cake and the filtrate are respectively treated, thus separating the two substances.
Example 4
And (5) carrying out environment-friendly sewage post-treatment. The silt is led into a sand filtering system with self-cleaning function, filtered water quality is checked and classified, and after the concentrated silt is checked to be qualified, a proper amount of kaolin or other fillers are added to prepare porous bricks or other building materials, so that no residue exists in sewage treatment and no pollution is caused.
Example 5
And (5) preparing drinking water. As shown in figure 1, the first group of self-flushing sand filter sticks are used for filtering visible foreign matters, the filtered coarse filtrate is led into a second stage of fine filtration, and the filtered coarse filtrate can be directly drunk after the hydration test is qualified, if sterile water is required to be obtained, a first stage of microporous filter membrane with the diameter of less than 1 mu m is added for filtration, and then the sterile drinking water can be obtained.
Example 6
And (3) water pollution treatment in the production of PCB (printed Circuit Board). The concept of garbage classification and timely treatment is adopted for the treatment of multiple water pollution processes, so that the complex process can be simplified, and the enterprise cost can be reduced.
The process drainage of each step in the pretreatment process of degreasing, four-section water washing, microetching and four-section water washing is treated in sequence, and the process drainage can be recycled. Oil removal, four-section water washing, microetching and four-section water washing process drainage in the development etching process are respectively treated by water; the links of acid washing, four-stage washing, alkali washing, four-stage washing, deionized water washing and the like in the browning process are respectively subjected to water treatment, so that the existing unified discharge and unified treatment is broken, and the water treatment difficulty in PCB production can be greatly relieved.
Is especially suitable for the gold plating and tinning process in copper deposition electroplating, pattern electroplating, outer layer etching and surface treatment.
Only one small filter can solve the problem in each link. The whole water pump filter is zero, only one water pump filter is arranged in each section, the water pump filter occupies little space, and the cost is greatly reduced.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
