Abstract
The utility model relates to a gold nanocomposite preparation contains gold waste water recovery gold system belongs to waste water recovery gold clean system. The load cauldron ejection of compact is connected with the confession stuff pump, and the confession stuff pump is connected with the pressure filter inlet, and the pressure filter liquid outlet is connected with the inlet of mother cistern, circulation tank respectively, and the liquid outlet of mother cistern, circulation tank is connected with the clear water pump inlet respectively, and the clear water pump liquid outlet is connected with the washing inlet and the adsorption tower of pressure filter respectively, and multistage adsorption tower is established ties the back and is gone out liquid and be connected with former water tank. The method has the advantages that the multistage adsorption tower realizes the preparation of gold nano composite materials, simultaneously realizes the recovery of process nano gold and reduces the loss of gold, and the mother liquor and the washing water are recycled after adsorption and purification to the process again, so that the recycling of system water is realized, the addition of new water is reduced, the cost is saved, and the method is more economic and environment-friendly.
Description
Technical Field
The utility model relates to a waste water recovery gold clean system, in particular to are used for gold nanocomposite preparation to contain gold waste water recovery gold system.
Background
The preparation of the gold nano composite material is a process of taking pretreated activated carbon (150-300 meshes) as a carrier and adsorbing nano gold under a certain condition so as to form the nano gold/carbon composite material. The method comprises three process stages of carrier pretreatment, nano gold sol preparation and loading. The carrier pretreatment requires the full mixing of the activated carbon and a pretreatment reagent, and comprises carrier washing, separation, pretreatment waste liquid utilization and carrier washing waste water utilization; the preparation of the nano gold sol requires constant temperature in the kettle, high material mixing speed and uniform mixing; the loading requires constant and uniform temperature in the kettle, the carrier-nano gold sol is fully mixed, and the process comprises the steps of purifying and separating the nano gold/carbon composite material and utilizing washing wastewater. The mother liquor and washing waste water produced in the purification, separation and washing processes of the loaded nano gold/carbon composite material contain a certain amount of nano gold, and a waste water gold recovery purification system is required to be provided in order to reduce gold loss and increase the pure water utilization rate.
Disclosure of Invention
The utility model provides a gold nanocomposite preparation contains gold waste water and retrieves gold system, the purpose provides one kind for realizing gold nanocomposite's preparation process, retrieve gold from load back mother liquor and washing liquid to accomplish the system that the pure water was recycled.
The utility model adopts the technical proposal that: including load cauldron, the confession stuff pump, the pressure filter, mother liquid groove, circulation tank, clean water pump, adsorption tower, former water tank, wherein the load cauldron ejection of compact is connected with the confession stuff pump, and the confession stuff pump is connected with the pressure filter inlet, and the pressure filter liquid outlet is connected with mother liquid groove, circulation tank's inlet respectively, and mother liquid groove, circulation tank's liquid outlet are connected with the clean water pump inlet respectively, and the clean water pump liquid outlet is connected with the washing inlet and the adsorption tower of pressure filter respectively, and the multistage adsorption tower goes out the liquid and is connected with former water tank after establishing.
The utility model has the advantages that: the multistage adsorption tower of the gold-containing wastewater gold recovery system for preparing the gold nanocomposite realizes the recovery of the nanogold in the process and reduces the loss of gold while realizing the preparation of the gold nanocomposite, and the mother liquor and the washing water are adsorbed and purified and then return to the process again to be used, so that the cyclic utilization of the system water is realized, the addition of new water is reduced, the cost is saved, and the multistage adsorption tower is more economic and environment-friendly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Please refer to fig. 1, which includes a loading kettle 1, a slurry supply pump 2, a filter press 3, a mother liquid tank 4, a circulation water tank 5, a clean water pump 6, an adsorption tower 7, and a raw water tank 8, wherein the discharge of the loading kettle 1 is connected with the slurry supply pump 2, the slurry supply pump 2 is connected with the inlet of the filter press 3, the outlet of the filter press 3 is respectively connected with the inlets of the mother liquid tank 4 and the circulation water tank 5, the outlets of the mother liquid tank 4 and the circulation water tank 5 are respectively connected with the inlet of the clean water pump 6, the outlet of the clean water pump 6 is respectively connected with the washing inlet of the filter press 3 and the adsorption tower 7, and the outlet of the.
The working process is as follows:
after the nano gold sol and the carrier are fully mixed, after the load is finished in a load kettle 1, slurry is conveyed to a filter press 3 through a slurry supply pump 2 for solid-liquid separation, separated mother liquor enters a mother liquor collecting tank 4, a clear water pump 6 is started after the mother liquor separation is finished, cleaning water in a circulating water tank 5 under the action of the clear water pump 6 enters a washing system of the filter press 3 for load circulating washing, after the washing is finished, the cleaning solution returns to the circulating water tank 5 again, and the gold nano composite material obtained after the water loading washing of the filter press 3 is subjected to manual subpackaging, so that the preparation process of the nano gold/carbon composite material is finished;
the loaded mother liquor in the mother liquor tank 4 and the washing liquid in the circulating water tank 5 enter a multi-stage adsorption tower 7 through a clean water pump 6 to be adsorbed and recycled, and the pure water liquid after adsorption treatment is pumped to a raw water tank 8 of a water purification system for recycling, so that the addition of fresh water is reduced.
