Automatic descaling system for high-pressure reactor of laterite nickel ore

An automatic descaling system for high pressure reactor of laterite nickel ore:

• comprising:
• a reactor, which has a feed end and a discharge end at its opposite ends;
• inside the reactor, multiple partition plates are sequentially arranged along the direction of material flow;
• these partition plates divide the interior cavity of the reactor into multiple compartments, with each two adjacent compartments being interconnected;
• multiple mixing devices, which correspond one-to-one with the multiple compartments, with each mixing device located within its corresponding compartment;
• multiple detection devices, which also correspond one-to-one with the multiple compartments, with each detection device located within its corresponding compartment for measuring the thickness of scale accumulation within that compartment;
• a scale removal assembly, which comprises an acid storage tank, multiple first connecting pipes, and multiple first control valves;
• the multiple first connecting pipes correspond one-to-one with the multiple compartments and are interconnected with them;
• each first connecting pipe is also connected to the acid storage tank, which is used to introduce acid solution into the corresponding compartment through each first connecting pipe to dissolve the scale;
• the multiple first control valves are installed correspondingly on the multiple first connecting pipes, serving to regulate the flow rate in or through the respective first connecting pipe;
• and,
• a control unit, which is electrically connected to the multiple mixing devices, the multiple detection devices, and the multiple first control valves;
• based on detection results of the detection devices, the control unit controls the operation of the corresponding mixing device and first control valve.
