Abstract
The invention relates to a chemical separation floatation column with a high enrichment ratio. The floatation column is provided with a jacket, and cooling water with different temperature can be introduced according to the requirement of the chemical separation or enrichment so as to improve the floatation efficiency; a floatation chamber is a spherical tube, so that the running path of bubbles can be changed, the running time of the bubbles in the floatation solution can be increased, the possibility that the bubbles are contacted with a trapped component is increased, and the edge effect can be avoided or alleviated; and an air chamber on the bottom of the floatation column has a large space, so that the air distribution and uniform air distribution of a sand core can be favored. According to the floatation column, the enrichment rate of the chemical separation or enrichment is higher than the ordinary floatation column without a jacket and with a straight cylindrical floatation chamber and a smaller air chamber space.
Description
Technical field
The present invention relates to the high Chemical Decomposition flotation column of a kind of accumulation rate, belong to Chemical Decomposition or beneficiation technologies field.
Background technology
FLOTATION SEPARATION is that a kind of modern chemistry separates and beneficiation technologies, and flotation column is exactly to realize high efficiency separation and the important equipment of enrichment.The height of flotation efficiency has great relation with flotation column.The height of flotation efficiency at first depends on bubble quantity and bubble, treats the contact probability of flotation particle and bubble, secondly is exactly the temperature of flotation and whether produces " edge effect ".The generation of bubble quantity and bubble and distribution in flotation cell solution and air distribution plate bubble and the uniformity of gas distribution are relevant, and be except the air distribution plate oneself factor, relevant with the factors such as size of the structure of air chamber, air chamber.Be applied to traditional flotation column that Chemical Decomposition or enrichment are used, air chamber is generally less, and carrier gas gets into the back air-flow and mainly concentrates in the middle of the air distribution plate, and the bubble of generation also mainly concentrates on the middle part of air distribution plate, makes the bubble skewness one of flotation cell.The contact probability of treating flotation particle and bubble is then relevant with the motion path of bubble in post, time etc.For traditional flotation column; Flotation cell is generally straight shape pipe; The length in bubble rising path depends on column length; And the draw ratio of the flotation column ratio of column diameter (column length with) can not be very big, so bubble is shorter relatively the running time in flotation cell solution, and is just less relatively by the contact probability of flotation ion and bubble.Simultaneously; Traditional straight shape flotation tube post is easy to generate " edge effect ", when bubble carries when treating that the flotation particle gets into organic facies, if carrier gas flux is bigger; Be prone to generation " edge amalgamation layer " (cascade) between organic facies and the tube wall and bubble is only passed through from cascade; The solute that carry on the surface turns back to water along cascade after bubble breaks, produce serious " short circuit " phenomenon, greatly reduces flotation efficiency.In addition, the mechanism of flotation mainly is by being adhered to by the flotation particle or be adsorbed on bubble surface, rise with bubble and bring in the organic facies, because the variation of density causes bubble to break, being come off by the flotation particle, and be dissolved in the organic facies owing to having certain lipophile.This to adhere to or adsorb mainly be physical absorption, and temperature is low to help absorption, and traditional flotation column does not have to supply the chuck of cooling water circulation, and the flotation efficiency of unit interval is also just relatively low.Therefore, if can address these problems, with improving to a certain extent by the separation and concentration efficient of flotation component.
Summary of the invention
The object of the invention just is to solve the deficiency that above-mentioned traditional chemical separating flotation post exists, and provides a kind of gas distribution even, can prolong the generation of treating flotation particle and bubble time of contact and reducing " edge effect ", can control the flotation column of low flotation temperature.
The objective of the invention is to realize like this: the Chemical Decomposition flotation column that a kind of accumulation rate is high, this flotation column be by (1) solution or solvent inlet, (2) flotation cell; (3) chuck, (4) cooling medium inlet, the outlet of (5) cooling medium; (6) water or organic facies outlet, (7) air distribution plate 4
#Core, (8) air chamber, (9) carrier gas inlet constitutes.
Can the cooling medium import and export of chuck be linked to each other with the outside cooling water system of post, logical cooling water (summer or circulate with phreatic water) reaches lowers the temperature or the purpose of temperature control.
Described flotation cell is a bulb tube.
Described air chamber has bigger space, and gas chamber volume is 1/4～1/2 of a flotation cell volume.
The present invention compared with prior art has the following advantages:
(1) flotation column that accumulation rate of the present invention is high is compared with traditional flotation column, in the flotation column bottom air chamber than large space is arranged, after carrier gas gets into.Because the expansion of gas, air-flow obtains certain buffering, and the air distribution plate pressurized is even, and the bubble of generation is homogeneous comparatively also.
(2) flotation cell of the present invention adopts spherical post; The straight shape post that the flotation cell of traditional flotation column of comparing adopts; Under the same conditions, the operating path that bubble rises is longer relatively, causes bubble longer the running time in flotation cell solution; Contact probability by flotation particle and bubble increases relatively, and spherical flotation cell is difficult for producing " edge effect " simultaneously.
(3) flotation column of the present invention has chuck design, can provide or control relatively low flotation temperature, helps by the absorption of flotation particle or adheres to.
Because above-mentioned advantage, flotation column of the present invention has higher separation or bioaccumulation efficiency.

Embodiment
The tributyl phosphate extraction system of lithium (lithium-ferric trichloride-tributyl phosphate-kerosene) is to be applied to that lithium magnesium in the salt lake bittern separates and the classical way of lithium enrichment, but the efficient of the disposable separation and concentration of lithium is not high, needs repeatedly extraction, or plural serial stage.With this system adopt flotation mode carry out can bigger raising first separation enrichment efficient.
Flotation column of the present invention and gas flowmeter, surge flask and source of the gas (oil-free air compressor, or air steel cylinder, or nitrogen steel cylinder) are constituted flotation unit.
Cooling medium inlet on the chuck 34, outlet 5 are linked to each other with 5 ℃ cooling water recirculation system.
Open source of the gas, regulate carrier gas flux, pour into by flotation solution the salt lake bittern system of ferric trichloride-tributyl phosphate of condition (controlled well) from solution or solvent inlet 1; Measure and adjust suitable carrier gas flux through soap film flowmeter; Add kerosene, flotation 5min; Emit water in the beaker of clean drying from water or organic facies outlet 6, get the content of the residual lithium of this determination of aqueous solution of certain volume.The flotation that the flotation unit that adopts the high Chemical Decomposition flotation column of accumulation rate of the present invention to constitute carries out, the floating and enriching rate of lithium is 93%.
