Description
Technical field
The invention belongs to Coal Washing Techniques field, be specifically related to a kind of floating agent of new and effective, energy-conserving and environment-protective.
Background technology
In floating separation process, be sorting valuable mineral and gangue mineral effectively, or separated various valuable mineral, often need to add some medicament, to change the physicochemical properties of mineral surfaces and the character of medium, these medicaments general designation floating agents.Floating agent can be divided into collecting agent, foaming agent, inhibitor, pH adjusting agent etc. traditionally.
At present, development along with washed coal industry and washing appliance, original common floating agent is general adopts poor oil product as raw material, have that consumption is large, weak effect, to shortcomings such as the healthy not guarantees of worker, do not reach the demand of existing industry development.
Summary of the invention
The present invention is directed to that current washed coal industry adopts that floating agent has that consumption is large, weak effect, to the healthy problem that there is no guarantee of worker, a kind of floating agent of new and effective, energy-conserving and environment-protective is proposed.
A floating agent for novel high-efficient energy-saving environment-friendly, is comprised of the material of following parts by weight: diesel oil 30-70 part, secondary octanol 10-50 part, enanthol 25-45 part, 2-Ethylhexyl Alcohol 15-35 part.
Preferably, this floating agent is comprised of the material of following parts by weight: 50 parts of diesel oil, 20 parts of secondary octanols, 35 parts of enanthol, 25 parts of 2-Ethylhexyl Alcohols.
A floating agent for novel high-efficient energy-saving environment-friendly, is comprised of the material of following parts by weight: coconut oil 10-30 part, diesel oil 30-70 part, secondary octanol 10-50 part, enanthol 25-45 part, 2-Ethylhexyl Alcohol 15-35 part.
Described coconut oil obtains slightly oil by being dried coconut flesh through mechanical expression, then makes through decolouring, deodorization.
Described diesel oil is oils, complicated hydro carbons (carbon number approximately 10～22) mixture.For diesel fuel.The diesel oil distillate allotment of mainly being produced by processes such as crude distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum cokings forms; Also can be produced by shale oil processing and coal liquefaction.
Described secondary octanol is the colourless inflammable oily liquids that has aromatic odor.Fusing point-38 ℃, boiling point 178-179 ℃, relative density 0.835, refractive index 1.4256,88 ℃ of flash-points (opening cup), viscosity (20 ℃) 8.2mPa.s.Water insoluble, dissolve in alcohol, ether and chloroform.
Described enanthol is colourless viscous liquid, can be miscible with ether, ethanol, there is aromatic odor.
Described 2-Ethylhexyl Alcohol is the colourless liquid that has special odor.Be dissolved in the water of approximately 720 times, dissolve each other with most organic solvents.
Beneficial effect of the present invention: floating agent of the present invention is nontoxic to have no irritating odor, efficient energy-saving is safe, bubbles, collecting performance is high, and consumption is 0.1-0.5kg/ ton coal slime, and consumption is few, saves coal separation cost, improves clean coal yield.
