Autogenous grinding type roller replacement reactor and re-dissolution-resisting multi-energy cascade purge technology

Abstract

The invention discloses an autogenous grinding type roller replacement reactor. The autogenous grinding type roller replacement reactor comprises a replacement reactor body, a liquid inlet, a liquid outlet, supporting rings, supporting wheels, a gear ring, a driving device, a driving gear ring, strengthened autogenous grinding grooves, feeding holes, shoveling plates, and powder shoveling plates.The re-dissolution-resisting multi-energy cascade purge technology is characterized in that the technology adopts a first replacement reactor, a second replacement reactor, a first clear liquid cushion tank, a filtering machine, a clear liquid storage tank, a lixivium storage tank, a second clear liquid cushion tank and connecting methods thereof. The connecting methods comprise single-stage series connection, multistage series connection, single-stage parallel connection, multistage parallel connection and circulation connection methods. The invention aims to solve the problems and difficulties that when a lixivium which is large in flow and low in zinc concentration is processed by conventional purge equipment and technology, particularly, when a zinc-ammonia complex solution obtained through an ammonia process electrolysis technology is processed, the quantity of involved processing equipment is large, the technological process is long, the area occupation is large, consumption of zinc powder is large, energy consumption is high, and the efficiency is low, and aims to provide the autogenous grinding type roller replacement reactor and re-dissolution-resisting multi-energy cascade purge technology which can achieve mass production.

Description

technical field [0001] The invention relates to a nonferrous metal smelting device and process method. In particular, it relates to a large-flow rapid purification device and method for ammonia method and ammonium salt method electrolytic zinc leaching solution, especially a self-grinding drum replacement reactor and an anti-returning multi-energy cascade purification process. Background technique [0002] The purification of electrolytic zinc leachate is the pre-process of electrolysis. Under the conventional method, the leachate replacement reactor is a stirring purification tank, and the replacement agent is zinc powder. The purification method is to control a certain temperature and pH value, and add an appropriate amount of zinc powder. Under contact with high potential impurity metal ions in the leach solution to produce a contact replacement reaction, reduce the impurity metal lead, copper, nickel, cobalt, etc., and reduce the content to a certain level, and at the sa...
