Accompanying drawing explanation
Fig. 1 is the overall structure figure of this system.
The specific embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the utility model is described in detail.
The present embodiment provides a kind of normal temperature and pressure regenerative system of active carbon for gold of carrying, this system can solve the warm method regenerating active carbon of existing height reactor economy poor, utilize advanced oxidation and chemical removal principle, by normal temperature and pressure, with cheap cost, obtain efficient regenerating active carbon.
In the present embodiment, realize system that this regenerative system adopts as shown in Figure 1, comprising: main treatment tank, trash eliminator, auxiliary water tank, storage acid tank, storage alkali tank, ozone generator, in and water tank and control module.Wherein, auxiliary water tank is connected with main treatment tank by pipeline, ozone generator is connected with main treatment tank, stores sour tank and is connected with main treatment tank by two separate pipelines, realizes respectively the sour tank of storage to main treatment tank, main treatment tank to the unilaterally connected of storing between sour tank.Main treatment tank by pipeline successively with trash eliminator and in be connected with water tank, in be connected with auxiliary water tank by pipeline with water tank, store alkali tank by pipeline with in be connected with water tank.In and water tank in be equipped with pH value sensor.
On two pipelines on connecting line on connecting line between main treatment tank and auxiliary water tank, between main treatment tank and trash eliminator, between main treatment tank and storage acid tank, storage alkali tank with in and the connecting line of water tank check valve is all installed.Above-mentioned all check valves and ozone generator are controlled by control module, in be connected with control module with the pH value sensor in water tank.
Iodine number means a basic numerical value of activated carbon adsorptive capacity, detects to judge the adsorption capacity of the active carbon after regeneration in the present embodiment by iodine number.In iodine number detects, the iodine number of original active carbon of take is carried out relative value comparison as 100%.Conventionally by iodine number lower than 70% carry gold with active carbon, be called and carry golden poor charcoal.
The normal temperature and pressure regenerative process that adopts this system to carry golden poor charcoal is:
First the golden poor charcoal of carrying that is 72% by iodine number to be regenerated enters in main treatment tank, control module is opened the check valve on auxiliary water tank and main treatment tank connecting line, in main treatment tank, inject running water, described in inciting somebody to action, carry golden poor charcoal and flood, the mass ratio of carrying golden poor charcoal and running water in assurance main treatment tank is to close this check valve after 1:2.5.Then control module starts ozone generator, by microbubble aeration, mix to injection of ozone in main treatment tank, the golden poor charcoal of carrying in main treatment tank is carried out to chemical catalytic oxidation (per ton carry golden poor charcoal required ozone amount per hour be 100g), and the opening time that control module is set ozone generator is 1 hour.In this process, in main treatment tank, carry golden poor charcoal in the direct oxidation of ozone and because carrying under the indirect oxidation effect of the free hydroxyl that golden poor charcoal produces ozone catalytic, by carrying each type organic adsorbing on golden poor charcoal, degrade.Complete after organic matter degradation, in main treatment tank for carrying golden poor charcoal and oxidation technology water after oxidation.Control module is opened the check valve between main treatment tank and trash eliminator, and the oxidation technology water in main treatment tank is drained into trash eliminator.Then control module is opened the sour tank of storage to the check valve on main treatment tank connecting line, by the hydrochloric acid that to store sour tank be 4% to implantation quality concentration in main treatment tank, the golden poor charcoal of carrying after oxidation in main treatment tank is carried out to pickling, when hydrochloric acid liquid level exceeds in main treatment tank, carry about golden poor charcoal height 25cm and close this check valve.By the immersion of 1 hour, the inorganic matter adsorbing on golden poor charcoal of carrying after oxidation is resolved to desorption.
After acid cleaning process completes, obtain the hydrochloric acid of proposing golden poor charcoal and mass concentration decline after wash-out.Control module is opened main treatment tank to the check valve of storing on sour tank connecting line, and the hydrochloric acid in main treatment tank, mass concentration being declined is drained back to the sour tank of storage, to again utilize after supplementing eo-acid.After acid discharge completes, close this check valve.Control module is opened the check valve on auxiliary water tank and main treatment tank connecting line, by auxiliary water tank, to injecting the carry golden poor charcoal of running water after to pickling in main treatment tank, carries out rinsing.To after wash-out propose continuous 3 rinsings of golden poor charcoal after obtain regenerated carbon.
Adopt GB/T12496.8-1999 " mensuration of wood activated charcoal test method iodine sorption value " test to show, the iodine number of the regenerated carbon after " oxidation-pickling " two steps are processed returns to 85%.For further improving regeneration effect, the regenerated carbon obtaining is entered to electrochemical processing cell, at current density 16mA/cm after rinsing
2under condition, carry out the electrochemical treatments of 2 hours, obtain the regenerated carbon after electrochemical treatments.Test shows, the iodine number of the regenerated carbon after electrochemical treatments returns to 92.5%.
For realizing recycling of washings and oxidation technology water, drain into oxidation technology water and the washings of trash eliminator, by trash eliminator, isolate the solid suspension carrying with water and reclaim; During oxidation technology water after separation and washings enter and water tank, the acidity of liquid in the in real time monitoring of pH value sensor during control module is passed through and in water tank and in water tank, if its acidity surpasses setting value 6, make to store alkali tank with in and pipeline in water tank connect, to in and water tank to add basicity be that 3% sodium hydroxide solution neutralizes, the water after neutralization is got back to auxiliary water tank and is treated again to utilize.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
