Liquid, liquid enters indium extraction process and carries out indium extraction before extracting, and the organic of P204 and kerosene composition can be used in indium extraction process
Phase, part organic phase enters in raffinate after the completion of extraction, and oil-containing in raffinate is caused to reach 100-150mg/L, this part
Raffinate enters main production system, and cathode plate scaling loss is serious in process in zinc electrolyzing, and cathode zinc yield is greatly lowered.
Utility model content
To solve the above problems, the utility model provides a kind of indium extraction raffinate oil removing system.
The utility model is achieved through the following technical solutions:
A kind of indium extraction raffinate oil removing system, including extraction raffinate defecator, the extraction raffinate defecator and gas lie prostrate slot, raffinate
Storage tank passes sequentially through overflow pipe connection, and the top that the extraction raffinate defecator, gas lie prostrate slot passes through the first return pipe and organic circulation slot
Connection, the raffinate storage tank is connected to by the second return pipe with the first return pipe, on first return pipe, the second return pipe
It is mounted on control valve, the extraction raffinate defecator, gas volt slot, raffinate reservoir bottom pass through drain pipe and raffinate treatment trough phase
It is connected to, the delivery pump for drain is provided on the drain pipe, the drain pipe lies prostrate slot, extraction with extraction raffinate defecator, gas respectively
The leading portion of extraction raffinate storage tank connection is mounted on shut-off valve, and the raffinate treatment trough is internally provided with active carbon, the raffinate
Treatment trough is connected to by connecting tube with raffinate # storage tank.
Compared with prior art, the beneficial effects of the utility model are: this practical raffinate is clarified continuously across extraction raffinate
Slot, gas volt slot and raffinate storage tank, three tank liquor positions keep highest liquid level to have reached maximum time of repose, utilize organic phase and its
The density of its liquid is different, and the kerosene separation in withdrawal liquid, stands rear upper part organic phase and be back to organic follow to greatest extent
Annular groove secondary use reduces the consumption of kerosene to achieve the effect that organic phase is separated with liquid；The liquid benefit of three slot lower parts
With the organic phase mixed in activated carbon adsorption property removal raffinate in raffinate treatment trough, effectively reduces organic phase and enter life
In production system, to guarantee that wet production system is stablized.
Detailed description of the invention
Fig. 1 is the schematic diagram of structure described in the utility model；
In figure: extraction raffinate defecator 1, raffinate storage tank 3, raffinate treatment trough 4, raffinate 1# storage tank 5, has gas volt slot 2
Machine circulating slot 6, overflow pipe 7, the first return pipe 8, the second return pipe 9, control valve 10, drain pipe 11, shut-off valve 12, delivery pump
13, connecting tube 14.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of indium extracts raffinate oil removing system, including extraction raffinate defecator 1, the extraction raffinate defecator 1 with
Gas volt slot 2, raffinate storage tank 3 pass sequentially through the connection of overflow pipe 7, and the top that the extraction raffinate defecator 1, gas lie prostrate slot 2 passes through first
Return pipe 8 is connect with organic circulation slot 6, and the raffinate storage tank 3 is connected to by the second return pipe 9 with the first return pipe 8, described
Control valve 10 is mounted on first return pipe 8, the second return pipe 9, the extraction raffinate defecator 1, gas lie prostrate slot 2, raffinate storage tank 3
Bottom is connected by drain pipe 11 with raffinate treatment trough 4, and the delivery pump for drain is provided on the drain pipe 11
13, the leading portion that the drain pipe 11 is connect with extraction raffinate defecator 1, gas volt slot 2, raffinate storage tank 3 respectively is mounted on shut-off valve
12, the raffinate treatment trough 4 is internally provided with active carbon, and the raffinate treatment trough 4 passes through connecting tube 14 and raffinate 1#
Storage tank 5 is connected to.
Working principle: raffinate enters extraction raffinate defecator 1 and lies prostrate slot 2 and raffinate by overflow pipe 7 followed by gas
Storage tank 3 carries out standing 4-6h in extraction raffinate defecator 1,2 two standing time of repose 2-3h of slot is lied prostrate in gas, in raffinate storage tank 3
Time of repose 6-8h is stood three times, is kept highest liquid level to have reached maximum time of repose by three above slot, is utilized organic phase
Different from the density of other liquid, the organic phases such as kerosene are in the top of three slots, and other liquid are in the lower part of three slots, quiet
Postpone on three slots part organic phase be back to by opening control valve 10 by the first return pipe 8 and the second return pipe 9 it is organic
