Description

It is a kind of for solving the problems, such as the tiny equipment of manganese sulfate class material crystal

Technical field

The utility model belongs to manganese sulfate class material crystallization technique field, refers specifically to increase it with temperature as manganese sulfate is this Solubility is lower, is opposite material with the crystallization of most of materials, specially a kind of thin for solving manganese sulfate class material crystal The equipment of minor issue.

Background technique

Increasingly depleted due to traditional resources such as petroleum, coals, new energy technology has become the pass of human kind sustainable development Key, lithium ion battery are expected to the storage that large-scale application cleans electric energy in electric car and solar energy, wind energy etc., therefore high purity sulphur The prospect of sour manganese is had an optimistic view of extensively.

About 30,000 tons of yield of China's LITHIUM BATTERY high purity manganese sulfate in 2014 are investigated according to recent market, global ternary in 2015 The shipment amount of material (that is: nickle cobalt lithium manganate Li (NiCoMn) O2, be good anode material of lithium battery) was increased than 2014 30% or so, wherein China accounts for 40% or more of global ternary material yield.According to Chinese industrial and equipment manufacturing industry department, informationization portion In January, 2016 gives out information, and accumulative production new-energy automobile 37.90 ten thousand of China in 2015 increases by 4 times on a year-on-year basis.Wherein, pure electricity Dynamic passenger car produces 14.28 ten thousand, increases by 3 times on a year-on-year basis；Plug-in hybrid passenger car produces 6.36 ten thousand, increases by 3 on a year-on-year basis Times.Pure electric vehicle commercial vehicle produces 14.79 ten thousand, increases by 8 times on a year-on-year basis；Plug-in hybrid commercial vehicle produces 2.46 ten thousand, together Than increasing by 79%.Message is emphasized simultaneously, New Energy Sources In China automobile production 9.98 ten thousand, increases by 3 times on a year-on-year basis in December, 2015.Its In, pure electric vehicle passenger car produces 2.57 ten thousand, increases by 114% on a year-on-year basis, plug-in hybrid passenger car produces 1.05 ten thousand, together Than increasing by 2 times；Pure electric vehicle commercial vehicle produces 5.78 ten thousand, increases by 6 times on a year-on-year basis, plug-in hybrid commercial vehicle production 5725 , increase by 51% on a year-on-year basis.Therefore, with the continuous propulsion of China's power battery industrialization, the demand of high purity manganese sulfate will be in future It will be significantly increased in several years.

High purity manganese sulfate is mainly used in the synthesis of nickel-cobalt-manganternary ternary anode material and manganate cathode material for lithium, ternary material Following development trend of material is developed to high capacity and inexpensive direction, and high-energy density is the permanent objective that lithium battery is pursued, The group of Ni, Co, Mn three's different proportion in tertiary cathode material is combined into power battery industry and provides greatly performance space. In ternary system, with the increase of Ni component, capacity is continuously improved, while because the content of Co is reduced, and material cost is also therewith Decline, and Mn then plays stability and safety in entire positive electrode system.Ternary material gradually squeezes cobalt acid lithium city , it is advantageous that: low cost, high capacity, development space are big.It, can be by adjusting Ni, Co, Mn three in ternary system Proportionate relationship obtain the positive electrodes of different characteristics, and in tertiary cathode material manganese price it is generally the least expensive, therefore improve manganese Ratio can substantially reduce battery cost, this also becomes the hot spot of industry research.Increasingly due to traditional resources such as petroleum, coals Exhaustion, new energy technology have become the key of human kind sustainable development, and lithium ion battery is expected to large-scale application in electronic vapour Vehicle and solar energy, wind energy etc. clean electric energy field, have a extensive future.

As described above, manganese sulfate is always important source material product indispensable in the development of the national economy, it is widely used.So And the production of manganese sulfate is constantly subjected to the puzzlement of evaporation energy consumption height and this tiny two hang-up of crystal grain, passes through scientific research personnel in recent years Ongoing effort with manufacturer has made some progress, but the contradiction of evaporation energy consumption and crystal size is still very prominent, mainly There are following two points.

(1) crystal grain size substantially meets requirement, but evaporation energy consumption is high

Concentration kettle arranges inner coil pipe, and by coil pipe heated material, secondary steam is directly discharged into atmosphere for raw steam or conduction oil Or absorbed by recirculated water, discharge about 100 mesh of crystal grain, basically reaches granularity requirements.But such evaporation and crystallization mode does not fill Point secondary steam heat is utilized, single effect evaporation energy consumption is high, and since coil heat exchange area is limited by space, occupied area Greatly.

(2) heat source repeatedly utilizes, and evaporation energy consumption reduces, but crystal grain is small

Manganese sulfate monohydrate crystal is white or baby pink monoclinic system fine crystallization, soluble easily in water, does not dissolve in ethyl alcohol, heating Start to lose the crystallization water to certain temperature.Different from most of crystallized stocks, solubility is increased with temperature manganese sulfate in water And reduce, however multiple-effect evaporation or MVR can utilize secondary steam, but be easy that manganese sulfate crystal is precipitated in heat exchanger tube heating surface, It is bonded on tube wall, causes manganese sulfate crystal to block heat exchanger tube, crystal is broken in cyclic process, and crystal out is very Carefully, centrifugation is difficult, and crystal moisture content is high after centrifugation, comes to subsequent drying belt difficult.

Therefore, with regard to above-mentioned both sides problem, for the evaporative crystallization of manganese sulfate class material, it is necessary to design a set of effective solution The certainly device and method of the tiny problem of its crystal, while simultaneous therefore energy conservation, it is with good economic efficiency.
