Abstract
The invention relates to a compound coal flotation agent, which is characterized in that the compound materials comprise the following raw materials in percentage by weight: 20-50wt% of wash oil, 105-0wt% of refined rubber oil, 10-50wt% of refined oil of waste plastics, 10-20wt% of aromatic hydrocarbon, 10-20wt% of waste grease of animals and plants, 10-20wt% of diesel fuel fraction, 10-20wt% of used oil and 0.1-10wt% of alkylphenol polyoxyethylene ether. A method for preparing the compound coal flotation agent comprises the steps of: distilling the raw materials except the alkylphenol polyoxyethylene ether at a high temperature to obtain mixed oil; adding the alkylphenol polyoxyethylene ether to the mixed oil; and stirring for 30 minutes at a normal temperature to obtain a finished product.
Description
Affiliated field
The present invention relates to a kind of release agent of coal when selected, say exactly, relate to a kind of coal flotation agent.
Technical background
Need carry out the flotation separation to fine coal when coal is selected in general, the mechanism of its flotation is to utilize the surface of coal and gangue class impurity water to be had the characteristic of DIFFERENT WET lubricant nature, relevant flotation agent is added in coal slurry, the coal cinder, under (or in stirring) state of stirring, bubbling air, the coal grain is attached on the formed foam of flotation agent, its coal grain emerges with foam, and scraped by being scraped trigger, thereby reach the requirement that coal grain and other impurity and cleaned coal are separated from each other, finally obtain head coal product.The medicament of present domestic flotation coal uses diesel oil mostly; The perhaps mixture of diesel oil and kerosene; Or secondary octanol, important industrial chemicals preparation that prices such as ring ethanol etc. are more expensive.Above cost of material is more expensive, causes cost to rise.From considering economically, need to select a kind of more cheap flotation agent with the flotation that adapts to coal and improve its economic benefit.
Summary of the invention
In order to solve some deficiency of prior art, the invention provides a kind of promptly can satisfy cleaned coal flotation purpose, the New Flotation Agent that can reduce production costs again.
Realize that the concrete technical scheme that above-mentioned purpose is taked is: select to bubble through the water column and oil-soluble material water insoluble and that can adhere to mutually with buckwheat coal and some impurity than water density is light, for example washing oil, waste plastics refining oil, scrap rubber refining oil, atmosphere 3rd side cut are oily, waste animal and plant fat, aromatic hydrocarbons (C8-10) etc., behind its distillation, catalytic pyrolysis, with the APES hybrid reaction that plays affinity interaction, peptizaiton, emulsification, can obtain multiple and flotation agent of the present invention again.
Implementing the useful effect of the present invention is: 1, because the selected prices of raw and semifnished materials are lower, therefore have good economic benefit.2, because raw materials used many be intermediate product or the accessory substance or the discarded object of relevant chemical products, so resource is extensive, easily acquisition.3, workable, conveniently require to adjust in process of production according to flotation.4, the flotation to coal is good, and generally about 10%, clean coal recovery reaches more than 50% cleans ash.Concrete data such as following table:
