Exhaust gas scrubbing equipment

After years of experience, Zhongji Sunward Technology Co., Ltd. and CINF Engineering Corporation Limited have developed proprietary technology and complete sets of equipment for the characteristics of hydrometallurgical tail gas, which are applied to the treatment of pressure leaching system exhaust steam, so that it can be discharged after reaching environmental protection standards. Specially designed for the "non-condensable gas and steam mixture" discharged from the pressure leaching system, the washing efficiency reaches more than 99%; the complete set of equipment integrates the functions of liquid storage, gas-solid centrifugal separation, and multi-stage washing. It has the advantages of compact structure, high washing efficiency, not easy to block, convenient maintenance, safety and reliability. At present, the technology has been applied to non-ferrous metal smelting, steel plants, new energy raw material smelting enterprises.

Anode cleaning Machine unit

The main function of the anode cleaning and flapping Machine unit is to transport the anode plate, clean the anode mud with high pressure water and reshape the anode plate. It is one of the core equipment of the zinc electrolysis workshop. For cast zinc electrowinning anode plates that do not need to be flattened, automatic batch chain beating can be carried out, which greatly improves the treatment efficiency of the anode and realizes the automatic operation of the zinc electrowinning workshop equipment.

Ore log washer

The trough washing machine is used for the first stage of washing operation to scrub -50mm (or -20mm) materials (including mud) separated from the cylinder washing machine. Its main tasks are two: one is to wipe off the clay (or powder ore) that is larger than 2mm and adheres to the surface of the ore (or gravel); The second is to recover (or discard) suspended materials (clay or powder ore) less than the design requirements (such as-2mm) from overflow to discharge, the lump ore (or gravel) larger than the design requirement (such as 2mm) is separated and recycled (or discarded) by countercurrent.
