The invention has high organic recovery rate, low energy loss and little slag discharging.
Description
Technical field
The present invention relates to a kind of method of handling the copper extraction system third phase.
Background technology
The traditional treatment method of copper extraction system third phase is to carry out liquid-solid separating and recovering extractant with pressure filter; Its method is (flow process is seen Fig. 1) as follows: third phase B in the extracting system is evacuated to the third phase treatment trough, and stirring or zeyssatite stir the back coating on canvas press cloth with clear water in the zeyssatite A adding third phase treatment trough; Third phase is got to pressure filter with HPP in the third phase treatment trough, and third phase is through pressure filter, and the water and the organic phase that do not contain solid particulate get in the organic phase treatment trough, in the organic phase treatment trough, clarify, and the isolating water in clarification back emits; Stir with organic phase in the atlapulgite C adding organic process groove, organic phase is returned the organic process groove through pressure filter after the filtration, and circulating filtration is clear up to filtrating, opens the valve that connects extracting system then, closes circulation valve, and organic phase is returned extracting system.
Traditional treatment process labour intensity is big, need regularly open pressure filter discharging filter cake, mounting or dismounting filter cloth and filter wash cloth; Health is difficult to safeguard that the pressure filter water clock is inevitable that the workman is stained with filter cake when operation also inevitable.
The formation of third phase is to be core with suspended solid in the feed liquid, and the solid suspension beyond the region of objective existence is a feed liquid, and feed liquid is outward an organism, i.e. organism construction materials contract liquid and suspended solid.Third phase does not destroy the stable form of third phase during through pressure filter, so use pressure filter to filter just the organism of carrying secretly in the third phase is reclaimed, and the organism that forms third phase emits with filter cake, the organism loss greatly, the recovery is not high.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective that above-mentioned prior art exists, and a kind of treatment process that can effectively destroy the stable state of copper extraction system third phase is provided, and reduces the organism loss, increases the organism recovery.
For this reason; The technical scheme that the present invention adopts is following: the treatment process of copper extraction system third phase, and its step is following: earlier the third phase in the copper extraction system is evacuated in the third phase treatment trough, then the third phase in the third phase treatment trough is squeezed into third phase with pump and handle in the whizzer; Rotary centrifuge; The water that does not contain solid particulate and the organic phase of gained are got in the organic phase treatment trough together, in the organic phase treatment trough, clarify, the discharging of clarification back separates the water that obtains;
In the organic process groove, add atlapulgite and organic phase stirring; The solution of gained carries out being back in the organic process groove after the spinning with the organic process whizzer; Carry out circular centrifugal and separate, clear up to organic phase, open the valve that connects extracting system then; Close circulation valve, organic phase is returned extracting system.
Key of the present invention is to have made traditional filtration unit into whizzer, and when third phase rotated in the whizzer high speed, the third phase stable state was broken, thereby forms organism in the third phase by efficient recovery, and the organism recovery is high; Save the use of super-cell, both avoided the generation of waste residue, also can not cause the organism loss.
The deslagging of whizzer of the present invention is the continuity automatic sludge discharge, does not need the manual operation deslagging; Whizzer is totally enclosed, and solution can be not excessive, and whizzer only needs pump point clear water to advance whizzer in time spent not just can be clean with the whizzer internal cleaning; Easy to operate, labor strength is low, and the plant operations hygienic condition are good; Organic recovery is high, and energy consumption is low, and deslagging is few.The use of whizzer makes the third phase in the third phase treatment trough can adopt conventional pump to squeeze in the whizzer, and needn't adopt HPP.
Above-mentioned treatment process, organic process whizzer have a plurality of and series connection, directly return extracting system from the organic phase that last whizzer comes out, and have saved this step of organic phase circulation, raise the efficiency; Described a plurality of organic process whizzer is arranged from a high position to the low level, and there is difference of altitude in adjacent whizzer, has realized that serial operation need not increase treatment trough and pump, has saved the energy and equipment.
Above-mentioned treatment process, atlapulgite adds by 1%～5% of organic phase volume, and this additional proportion is preferable, and cost is economized, and the recovery is high.
Above-mentioned treatment process, described whizzer is selected horizontal centrifuge for use, equipment to take volume little.
The invention solves all shortcomings of conventional process third phase method, have the following advantages: third phase is handled automatically continuously, and easy to operate, labor strength is low, and the workshop hygiene environment is good, and organic recovery is high, and energy consumption is low, and deslagging is few.
Below in conjunction with Figure of description and embodiment the present invention is described further.
