Abstract
The invention discloses an energy-saving gold-carried carbon desorption electrolysis method. By means of the method, solution tanks of two desorption electrolysis devices are connected through a pipeline and internally provided with heat exchangers; the first desorption electrolysis device enters the pressure release and liquid discharge stage after completing desorption electrolysis, and at the moment, heat is transferred to a solution in the solution tank of the second desorption electrolysis device through the corresponding heat exchanger, so that the heat supplemented for a heater in the second desorption electrolysis device is reduced; and in a similarly way, heat of the second desorption electrolysis device is transferred to a solution in the solution tank of the first desorption electrolysis device. By means of the method, the heat loss in the desorption electrolysis process is minimized, and waste heat is fully recycled; and meanwhile, the desorption electrolysis time is shortened. Thus, the power consumption is lowered, and the running cost of the desorption electrolysis devices is reduced.
Description
Technical field
The present invention relates to gold loaded carbon desorption electrolysis process energy-conservation in a kind of charcoal slurry gold extraction technology, particularly one carbon slurry process energy-saving and emission-reduction in gold industry, the gold loaded carbon desorption electrolysis process of cost efficiency.
Technical background
Technology for gold carried by charcoal slurry is modern main pan technique, and due to the enhancing further of the domestic and international environmental consciousness of attention and people further to environmental protection, the application without desorbing electrolytic device warm in cyanogen becomes more and more extensive.Under normal circumstances, gold loaded carbon belongs to pressurized vessel category without desorption electrolytic equipment warm in cyanogen, this equipment series operational system temperature 150 ± 2 DEG C, pressure 0.45 ~ 0.5MPa, regulation in " People's Republic of China's special safety equipment method ": special safety equipment work should be adhered to safety first, puts prevention first, energy-conserving and environment-protective, the comprehensive regulation principle.
Therefore, from the viewpoint of the rise etc. of safety first, energy-conserving and environment-protective and cyanide free process gold extraction technology, reduce the energy consumption of desorbing electrolytic device, ensure that the environmental protection of desorbing electrolytic technique is significant.
Summary of the invention
The invention provides gold loaded carbon desorption electrolysis process energy-conservation in a kind of charcoal slurry gold extraction technology.
The method is: connected by pipeline by the solution tank of two cover desorbing electrolytic devices, solution tank is built with heat exchanger; Complete desorbing electrolytic at first set desorbing electrolytic device, enter pressure release blowdown period, now heat is passed to the solution in the solution tank of the second cover desorbing electrolytic device by heat exchanger, which reduces the heat that in the second covering device, well heater is added; In like manner, the heat of the second cover desorbing electrolytic device passes to the solution in the solution tank of first set desorbing electrolytic device.
Beneficial effect of the present invention:
The calorific loss achieved in desorbing electrolytic process minimizes, and fully recycles waste heat, shortens the time of desorbing electrolytic simultaneously.Therefore, the power consumption decreased, reduces the running cost of desorbing electrolytic device.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
Embodiment
As shown in Figure 1, method of the present invention is: be connected by pipeline by the second solution tank 2 that first solution tank 1 and second of first set desorbing electrolytic device overlaps desorbing electrolytic device, in first solution tank 1 and the second solution tank 2, primary heater 5 and secondary heater 6 are housed respectively, first solution tank 1 and the second solution tank 2 are all provided with heat exchanger, be vented at first set desorbing electrolytic device, during discharge opeing, first desorption column 3, the first solution tank 1 got back to by high-temp liquid in first electrolyzer 7 and primary heater 5 and the heat exchanger of gas in the second solution tank 2, unnecessary gas is arranged outward by chimney, in this way, the heat of high-temperature gas and liquid is passed to the stripping liquid in the second solution tank 2, heating desorption liquid, shorten the time of the second cover desorbing electrolytic device partial circulating, namely the working hour of well heater is shortened, reduce power consumption.The stripping liquid temperature of getting back in the first solution tank 1 reduces, and the gas volume of outer row tails off, and reduces calorific loss.In like manner, when the second cover desorbing electrolytic device enters blowdown period, the second solution tank 2 got back to by high-temp liquid in second desorption column 4, second electrolyzer 8 and secondary heater 6 and the heat exchanger of gas in the first solution tank 1, unnecessary gas is arranged outward by chimney, in this way, the heat of high-temperature gas and liquid is passed to the stripping liquid in the first solution tank 1, heating desorption liquid, shorten the time of first set desorbing electrolytic device partial circulating, namely shorten the working hour of well heater, reduce power consumption.
