Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical technology, specifically to a tail gas scrubbing device for hydrometallurgical processes. Background Technology

[0002] Hydrometallurgy is a method in which ores, mineral concentrates or other raw materials are brought into contact with aqueous solutions or other liquid phases, and useful metals contained in the raw materials are transferred into the liquid phase through chemical reactions. The various useful metals contained in the liquid phase are then separated and enriched, and finally recovered in the form of metals or other compounds.

[0003] Hydrometallurgy generates pollutants such as wastewater and exhaust gas when processing metals. Scrubbers are a new type of gas purification equipment used to treat harmful components in exhaust gas and clean it. However, the scrubbing equipment currently in use does not provide dust protection for the blower. When exhaust gas enters the equipment for treatment, it will cause long-term corrosion and damage to the blower, greatly shortening its service life.

[0004] Therefore, a novel tail gas scrubbing device for hydrometallurgical processes is proposed to solve the above problems. Utility Model Content

At the same time, the fixing ring is sleeved on the outside of the positioning rod to limit and fix the four corners of the demisting layer, the first filling layer, and the second filling layer. The support base plate provides strong support and improves the balance.

[0018] (3) By setting up a drive motor, linkage shaft, stirring blade, medicine storage cylinder, mounting base and medicine inlet, the medicine storage cylinder is placed above the mixing box, and the mounting base can be rotated and fixed inside the medicine inlet for easy addition of solution. After the linkage shaft rotates, the stirring blade is used to fully mix and stir the solution to avoid precipitation and improve the use effect of the solution. Attached Figure Description
