Description
Technical field
Present technique relates to the recycling device of oxidation solution in the pre-coating light sensitive plate production.
Background technology
When pre-coating light sensitive plate is produced, in the wet section electrochemical reaction process the multinomial acid reaction that relates to is arranged, as using hydrochloric acid in the electrolysis, the anodic oxidation section is used sulfuric acid, and manufacturing technique requirent must be with the control of the aluminium ion concentration in the working solution within the specific limits, be no more than the 1.5%(different manufacturers such as aluminium ion concentration in the oxidation solution slightly variant), along with electrochemical reaction continue carry out, aluminium ion concentration is too high can to affect the product inherent quality, therefore the pre-coating light sensitive plate production line all is equipped with the laboratory personnel aluminium ion concentration in the working solution is carried out periodic monitor, when aluminium ion concentration reaches certain numerical value, must carry out discharge opeing, fluid infusion operates to reduce the aluminium ion concentration in the working solution.
In the pre-coating light sensitive plate production process, the main consumption of sulfuric acid is not in the process that participates in electrochemical reaction, and be above-mentioned discharge opeing, fluid infusion process, sulfuric acid a large amount of and that have neither part nor lot in chemical reaction is wasted in this process, after entering cesspool, also need with liquid caustic soda it to be neutralized, to reach the wastewater discharge standard of national regulation.So this traditional discharge opeing, fluid infusion mode have been wasted a large amount of sulfuric acid and corresponding liquid caustic soda.
Technology contents
The purpose of present technique provides a kind of aluminium ion is concentrated in the least possible raffinate and is discharged, the cyclic utilization system of oxidation solution during minimizing is produced the pre-coating light sensitive plate of the waste of sulfuric acid and corresponding liquid caustic soda.
The cyclic utilization system of oxidation solution during this pre-coating light sensitive plate is produced, comprise the elevator pump of the oxidation solution in the oxidation work box being sent into the waste liquid import of diffusion dialysis device, the water source communicates with the water inlet of diffusion dialysis device, and the recovery liquid outlet of diffusion dialysis device communicates with the oxidation work box.
The beneficial effect of present technique: diffusion dialysis is the process of utilizing pellicle or perm-selective ion-ex-change membrane that the solute in the solution is moved to low concentration one side by film by high concentration one side.The diffusion dialysis device belongs to existing apparatus.For the utility model, oxidation solution and water are respectively through waste liquid import and the reverse both sides that pass into film of water inlet, because the selection of concentration difference and film sees through effect, sulfuric acid in the oxidation solution enters the compartment of film one side, and aluminum sulfate is still stayed in the former oxidation solution compartment, the result of dialysis makes a side compartment of film interior for mainly containing the diffusion liquid of sulfuric acid, then for mainly containing the raffinate of aluminum sulfate, has so just reached the purpose of reclaim sulfuric acid from oxidation solution in the opposite side compartment.The diffusion liquid that mainly contains sulfuric acid enters the oxidation work box and carries out recyclingly through reclaiming the liquid outlet, and the raffinate that mainly contains aluminum sulfate is then discharged from the raffinate outlet of diffusion dialysis device.Because only having a small amount of sulfuric acid in the raffinate, thus need and its in and the liquid caustic soda consumption seldom.Native system is concentrated to aluminium ion in the least possible raffinate and is discharged, and reduces the waste to sulfuric acid and corresponding liquid caustic soda.
The cyclic utilization system of oxidation solution during above-mentioned pre-coating light sensitive plate is produced, the recovery liquid outlet of diffusion dialysis device communicates with reclaiming liquid storage tank, reclaims liquid storage tank and communicates with the oxidation work box.
The cyclic utilization system of oxidation solution during above-mentioned pre-coating light sensitive plate is produced, the raffinate outlet of diffusion dialysis device communicates with the raffinate storage tank, and the liquid caustic soda adding apparatus is set on the raffinate storage tank.
The cyclic utilization system of oxidation solution during above-mentioned pre-coating light sensitive plate is produced, it comprises the filter that filters sending into diffusion dialysis device waste liquid import oxidation solution before.
Description of drawings
Fig. 1 is the cyclic utilization system schematic diagram of oxidation solution during pre-coating light sensitive plate is produced.
The specific embodiment
By reference to the accompanying drawings present technique is further described below by embodiment.
Cyclic utilization system referring to oxidation solution in the pre-coating light sensitive plate production shown in Figure 1 comprises oxidation solution circulation line, diffusion dialysis system.The oxidation solution circulation line comprises oxidation work box 1, elevator pump 2, filter 3 and corresponding pvc pipe road.The diffusion dialysis system comprises feed liquor head tank 4, water head tank 5, diffusion dialysis device 6, raffinate storage tank 7, reclaims liquid storage tank 8.
In process of production, by elevator pump oxidation solution is extracted out from the oxidation work box, be promoted to the feed liquor head tank after being filtered.Liquid in feed liquor head tank and the water head tank is injected respectively waste liquid import and the water inlet of diffusion dialysis device, after the diffusion dialysis through the diffusion dialysis film in the diffusion dialysis device, most of sulfuric acid in the oxidation solution separates with wherein aluminum sulfate by the diffusion dialysis film, then flows into to reclaim liquid storage tank; And the raffinate of main sulfur acid aluminium enters the raffinate storage tank, and the sulfuric acid that reclaims in the liquid storage tank can re-inject oxidation work box continuation use, and raffinate then effluxes, and discharges after neutralisation treatment.
Present technique utilizes the diffusion dialysis film to carry out diffusion dialysis and process containing aluminum ions oxidation solution (sulfuric acid solution about 20%), and wherein aluminium ion is isolated in the raffinate, and the sulfuric acid solution of most of (approximately 80%) is reclaimed, and injects the oxidation work box and reuses.When producing, constantly the hydrogen ion in the oxidation solution is separated with aluminium ion by the diffusion dialysis film in the existing diffusion dialysis device, reach the recycling of sulfuric acid, can reach like this purpose of saving a large amount of sulfuric acid and liquid caustic soda.Take the production line of a speed of a motor vehicle 10m/min as example, original mode needs approximately 5 tons in 98% sulfuric acid per month, and this improvement can cause saves 4 tons in 98% sulfuric acid per month at least, and saves simultaneously 10.6 tons of 30% liquid caustic soda, to energy-saving and emission-reduction, reducing production costs is significant.
