Overflow type multi-compartment autoclave and process thereof

Abstract

The invention provides an overflow-type multi-bay autoclave and a process thereof, wherein the autoclave comprises a autoclave body and a plurality of stirrers; the stirrers are arranged on the autoclave body and extended to the inside of the autoclave body; the top of the autoclave body is provided with a feeding hole and a finished product outlet; one bay plate which is provided with a size-adjustable overflow hole on the top and can enable slurry to flow through the tops of bay plates; bay chambers are formed on two sides of each bay plate; the overflow holes of the adjacent bay plates have a fall for ensuring that retention time of the slurry inside every bay chamber is equal; and coarse material outlets are correspondingly arranged on the autoclave body below every stirrer. The process comprises the following steps: the slurry entering the inside of the autoclave body from the feeding hole sequentially enters every bay chamber from the overflow holes on the bottom of the bay plates, and the retention time of the slurry inside every bay chamber is kept identical. The autoclave can effectively solve the problems that the prior multi-bay autoclave deposits materials on the innerbottom and on the bottom of the bay plates and is low in leaching efficiency.

Description

technical field [0001] The present invention relates to hydrometallurgy technology, more specifically, relates to an overflow horizontal multi-compartment autoclave and its technique. Background technique [0002] With the advantages of hydrometallurgy in environmental protection and energy, hydrometallurgy has become the main method of the metallurgical industry, and with the improvement of domestic equipment manufacturing level, the key equipment of hydrometallurgy: multi-compartment horizontal leaching pressurization Kettle, already due to the original 10m 3 Kettle developed to nearly 900m 3 The diameter of the kettle has grown from the original 1.6 meters to 5.3 meters, and the number of reaction compartments has grown from the original 2-3 to 7-8. [0003] With the use of large-scale multi-compartment autoclave, the original operation process and autoclave can no longer meet the requirements of actual safety production, resulting in material accumulation at the bottom...

Problems solved by technology

[0003] With the use of large-scale multi-compartment autoclave, the original operation process and autoclave can no longer meet the requirements of actual safety production, resulting in material accumulation at the bottom of the autoclave and the bottom of the compartment plate, reduced leaching efficiency, and stirring machinery Serious engineering accidents such as sealing and feeding caused the equipment to stop, which seriously affected the safety of production
