At the same time, the working pressure of the high system is high, up to 0.5Mpa, which is 0.2Mpa~0.5Mpa higher than the working pressure of the conventional system. Under the conditions of high temperature and high pressure, the desorption and electrolysis speed of gold-loaded carbon is faster, and can be achieved within 12 The entire desorption and electrolysis work of a batch (500kg) of gold-loaded carbon can be completed within 14 hours to 14 hours, which shortens the working time by nearly three times compared with the conventional system. <br>2.

The pressure cover of the electrolytic cell has a total of 40 M20 screws, and opening the electrolytic cell requires manual unscrewing of these screws, which appears cumbersome and cumbersome.

First, the advantages and disadvantages of high temperature and high pressure desorption electrolysis equipment are introduced.<br> (1) Advantages:<br> 1. The desorption and electrolysis speed of gold-loaded carbon is faster.<br> Because the working temperature of desorption electrolysis in this system is high, reaching 150℃, which is more than 30℃ ~ 55℃ higher than that of the conventional system, and the working pressure of the high system is high, reaching 0.5Mpa, which is 0.2 MPa ~ 0.5 MPa higher than that of the conventional system. Under the conditions of high temperature and high pressure, the desorption electrolysis speed of gold-loaded carbon is faster, and a batch (500kg) of gold-loaded carbon can be completed within 12 hours ~ 14 hours.<br> 2, cyanide-free desorption and low energy consumption<br> Sodium cyanide and sodium hydroxide need to be added in the preparation of conventional desorption solution, which not only increases the cost of desorption electrolysis, but also worsens the operating environment.<br> The system only needs to add sodium hydroxide instead of sodium cyanide, which not only reduces the operating cost, but also keeps the environment clear.<br> The desorption temperature in the system is the same as the electrolysis temperature, and there is no heat exchanger, so the heat preservation effect is good.<br> Because of its high working speed, the power consumption of the system is 1/2 ~ 1/4 of that of the conventional system.<br> 3, automatic control settings<br> Liquid level buffer mechanism: The liquid volume of the system will fluctuate due to the vaporization of liquid during operation and the change of system pressure. Therefore, the system has specially set up a liquid level buffer mechanism, which can automatically offset the change of liquid level and always maintain the normal operation of the system.<br> Temperature control system: when the temperature reaches the set value, the system automatically turns off some electric heaters, and the remaining electric heaters automatically maintain the working temperature of the system. If the system temperature is lower than the set lower limit, the turned-off electric heaters are put into use, so that the system temperature is always stable at the set value.<br> 4. There are three safety measures.<br> In order to ensure the safety of the system, three safety measures were taken.<br> First, the system itself is intelligent: when the circulating pump is not running, the liquid in the system will not flow. In order to prevent the local high temperature from vaporizing and boosting, the electric heater will be automatically powered off.<br> When the pressure rises at a certain position due to blockage, the electric heater will automatically stop working.<br> When the circulating pump resumes operation or the pressure is reduced, the electric heater will automatically put into operation.<br> Second, it has a special pressure relief mechanism: when the system pressure rises to a certain value, the mechanism automatically opens to relieve the pressure and adjusts the pressure to a normal value.<br> Third, the safety valve: only the above two measures will work if they fail together.<br> (2) Disadvantages:<br> 1. Desorption electrolysis, after all, works under the conditions of high temperature and high pressure, and the desorption solution is prepared with strongly corrosive soda ash (sodium hydroxide). Therefore, incorrect operation or any carelessness may cause equipment and personal accidents.<br> 2. There are 40 M20 screws in the pressure cover of the electrolyzer, so it is cumbersome and troublesome to open the electrolyzer manually.
