Description
Technical field
The present invention relates to a kind of recovery processing technique, more particularly to a kind of recovery processing technique of waste nickel hydrogen battery.
Background technology
In numerous batteries, Ni-MH battery causes the weight of high risks due to electrode material without cadmium, lead, mercury etc. to environment
Metallic element and be known as " environment-friendly battery ", but the continuous improvement with international community to environmental protection requirement, in discarded object
The limitation for being possible to jeopardize the elements such as Ni, Cr, V of ecological environment will be more and more stricter.Oneself is all had in some trans-corporations
Battery recycling system, strict limitation of various countries' Law on Environmental Protection to metal discharge amount necessarily promote the recovery of Ni-MH battery.
The recovery of waste nickel hydrogen battery mainly has pyrogenic process recovery process and wet recycling process, valuable metal after pyrogenic process recovery
Nickel forms dilval, and rare earth is transferred in slag, reclaims more difficult again；Product outlet is more after hydrometallurgic recovery, valuable
Metallic nickel can make electrolytic nickel or nickel sulfate crystallization, and rare earth is reclaimed with Multiple salts forms, can reused.And wet method is returned at present
Skill of knocking off will be pre-processed before leaching to waste nickel hydrogen battery, and main technological route is that waste nickel hydrogen battery is broken using machinery
Shell removes box hat, then crushes again, and sub-elects diaphragm paper therein, and so as to obtain electrode material, further leaching etc. is wet
Method is reclaimed.This pretreating process route is more complicated, and crust breaking device is easy to wear, and maintenance cost is high, and shell-breaking efficiency is relatively low.Cause
This, the waste nickel hydrogen battery pretreating process that can be matched with wet processing for finding complete set turns into when previous main class
Topic.
The content of the invention
The present invention is intended to provide a kind of process is simple, novelty, the recovery of waste nickel hydrogen battery crushed in advance without battery
Handling process.
The present invention is realized by following scheme：
A kind of recovery processing technique of waste nickel hydrogen battery, by material waste nickel hydrogen battery, reducing agent, vulcanizing agent and slag making
Agent is well mixed in being added to graphite crucible by a certain percentage, and the graphite crucible that material is will be equipped with afterwards is placed in calciner,
Calciner starts progressively to be warming up to 1450~1600 DEG C and held for some time, until W metal in waste nickel hydrogen battery,
Co, Fe form sulfide or complex sulfide, rare earth element form compound, and product mix is taken out in finally cooling.Ordinary circumstance
Under, the W metal in waste nickel hydrogen battery, Co, Fe can be formed sulphur by the soaking time control in calciner in more than 1h
Compound or complex sulfide, rare earth element form compound, it is contemplated that operating efficiency, and soaking time general control is for 1~3h
Can.Convenience is considered in process of production, also first graphite crucible can be first placed in and process warm is progressively warming up in calciner
Degree, then again toward material is added in graphite crucible, insulation reaction afterwards.
Further, the consumption of the reducing agent is the 10~15% of waste nickel hydrogen battery addition；The vulcanizing agent
Consumption is the 20~25% of waste nickel hydrogen battery addition；The consumption of the slag former for waste nickel hydrogen battery addition 25~
30%.
The reducing agent is activated carbon, and the vulcanizing agent is elemental sulfur, and the slag former is calcium oxide and silica
Mixture, calcium oxide is (5~7) with the mass ratio of silica：(8~10).
Further, the calciner is the one kind in resistance furnace, smelting furnace, electric arc furnaces.
The recovery processing technique of waste nickel hydrogen battery of the invention, process is simple, novelty, eliminates waste nickel hydrogen battery
, directly be placed in battery in calciner and reacted with reducing agent, vulcanizing agent etc. by broken apart step, and roasting condition
Simply, without gas shield, and carry out at ambient pressure.What the recovery processing technique of waste nickel hydrogen battery of the invention was obtained
Product mix is broken, can directly be leached with sulfuric acid, is follow-up further therein using the recovery of wet processing separating-purifying
Valuable metal nickel, cobalt and rare earth provide advantage；Conventional way is usually that product mix is used into sulfuric acid leaching, leachate
Using common process as precipitated recovering rare earth by sodium sulphate, the solution after rare earth will be removed using common process such as through yellow sodium iron
Extracting and purifying separation and recovery nickel, cobalt metal after alum and removing iron.
