Abstract
The invention discloses a coal compound flotation agent which is composed of a trapping agent, a foaming agent, an activating agent and an inhibitor. The trapping agent comprises diesel oil, turpentine and nonpolar oil. The foaming agent comprises fusel oil and JF oil. The activating agent is higher aliphatic alcohol polyoxyethylene ether, and the inhibitor is carboxymethylcellulose. Compared with an existing flotation agent, the defect that in a traditional technology, various raw materials are stored and added in a classified mode is overcome, the using amount only needs to be adjusted according to production conditions on the site, a higher flotation speed and a wide flotation adaption range are achieved, products are nonhazardous, and smell is good.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to coal separation high efficiency composition flotation agent.
Background technology
Flotation coal separation method utilizes a kind of coal preparation method basis of coal particles Surface Physical Chemistry different in kind feature being carried out sorting to coal particles, is also a kind of coal preparation method of current extensive use.Coal particles surface all also exists hydrophobicity, adds flotation agent simultaneously and improves its hydrophobicity, can be floated over the liquid surface, ore deposit of flotation device, finally recycle by various PROCESS FOR TREATMENT coal particles.
The flotation agent that flotation coal separation utilizes plays an important role to coal separation effect.And in traditional flotation coal preparation technique, use collecting agent to treat coal grain in coal separation mud and spoil mud and have different compatibility and selective thus form hydrophobic cleaned coal and the tiny group of hydrophily coal slime, foaming agent then has different floating carrying velocities to the cleaned coal formed and the tiny group of coal slime, and then constantly form a relative cleaned coal froth bed and coal slime layering, finally successfully realize FLOTATION SEPARATION.Because conventional art flotation agent used adopts plurality of raw materials classification store and add, equipment investment is larger, technology relative complex; And each component is comparatively complicated in the technological adjustment of flotation site, higher and random bigger than normal to the skill requirement of operating personnel.
Summary of the invention
Main purpose of the present invention is to provide a kind of coal composite floating chemical, and attach most importance to produce debugging in early stage formula, the formula used same coal is relatively stable, disposable interpolation, and specific aim is good, effective.Avoid tradition and use blindness, the randomness that the one pack system such as collecting agent, foaming agent is sub-category, multi-line adds and regulates.
Technical solution disclosed by the invention is: the coal composite floating chemical provided comprises collecting agent, foaming agent, activator and inhibitor, and the mass percent proportioning of four kinds of preparations is:
Collecting agent: 60% ~ 85%, foaming agent: 10% ~ 30%
Activator: 1% ~ 5%, inhibitor: 3% ~ 5%
Containing diesel oil 20 ~ 40% in said collecting agent, turpentine oil 5% ~ 15%, non-polar oil 45% ~ 75%, foaming agent contains fusel oil 50% and JF oil 50%, and activator is higher aliphatic APEO, and inhibitor is carboxymethyl cellulose.
Beneficial effect of the present invention is, coal composite floating chemical introduces multiple collecting agent and foaming agent compound on the basis of conventional process techniques, and add activator, inhibitor in right amount, according to adsorbing and inhaling principle altogether, thus change this flotation agent treat coal grain in coal separation mud and spoil mud compatibility, improve that it is selective, coal flotation agent use amount is more economized, and is 50% or less of other consumption.Coal composite floating chemical can be used as one-component when using adds, and avoids and adds the interpolation of the multi-pipeline such as collecting agent and foaming agent respectively, simplify technological process.Coal composite floating chemical has good flotation effect to the different floatation process of Coal rank, improves clean coal yield, reduces cleans ash, strong adaptability.Simultaneously product is non-flammable product, non-stimulated smell, is conducive to safety in production and healthy.
Detailed description of the invention
For achieving the above object, coal composite floating chemical provided by the invention adopts multiple collecting agent and foaming agent compound, and add higher aliphatic APEO and carboxymethyl cellulose in right amount, according to adsorbing and inhaling principle altogether, change the compatibility that coal flotation agent treats coal grain in coal separation mud and spoil mud, improve that it is selective.Selected raw material is nontoxic material, should be noted that deslagging removal of impurities in process of production, fully stirs and mix.This programme is prepared coal composite floating chemical formula and is comprised collecting agent, foaming agent, activator and inhibitor, and the mass percent proportioning of four kinds of preparations is:
Collecting agent: 60% ~ 85%, foaming agent: 10% ~ 30%
Activator: 1% ~ 5%, inhibitor: 3% ~ 5%
Containing diesel oil 20 ~ 40% in collecting agent, turpentine oil 5% ~ 15%, non-polar oil 45% ~ 75%, foaming agent contains fusel oil 50% and JF oil 50%, and activator is higher aliphatic APEO, and inhibitor is carboxymethyl cellulose.
Hereafter will describe embodiments of the invention in detail, and in embodiment, only select a kind of proportioning to implement.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they mutually can be combined and be combined with each other thus reach better technique effect.
Embodiment 1: foaming agent is added in collecting agent, then add higher aliphatic APEO and carboxymethyl cellulose fully stirs and mixes, carry out deslagging removal of impurities in production process.Wherein, foaming agent is 6kg fusel oil and 6kgJF oil, and collecting agent is 20kg diesel oil, 12kg turpentine oil and 50kg non-polar oil, higher aliphatic APEO 2kg, carboxymethyl cellulose 4kg.
For the coal sample of Ji Kuang group clouds cloud Coalmine Coal Preparation Plant, its coal ash is divided into 23.5%, and the thin mud part being less than 0.01mm accounts for 25%, and pan feeding floatation concentration is 100-120g/L, coal flotation agent is disposable add after.Idiographic flow is: 1, output tail coal after dense-medium separation; 2, tail coal enters ore pulp and generates bucket generation ore pulp after crushing and screening; 3, disposablely in premix bucket coal flotation agent and ore pulp premix is added; 4, premix, enters flotation device flotation; 5, the cleaned coal foam of emersion enters cleaned coal bucket and send press filtration output cleaned coal, and tail coal water enters tailing pit, and its underflow send press filtration output tail coal mud.
Its to the flotation results of coal as shown in following table 1 and table 2:
Table 1
Table 2
Can be found by table 1, along with the increase of coal composite floating chemical consumption, the flotation effect of coal sample be become better and better, scrape the also corresponding shortening of bubble time; Contrast table 1 and table 2 can find, when using coal composite floating chemical ratio sec-octyl alcohol and diesel oil as flotation agent, the productive rate of concentrate is higher, and therefore, when reaching same effect, coal composite floating chemical consumption is more economized, and reduces production cost; When using composite floating chemical, it is also shorter to scrape the bubble time simultaneously, and flotation speed is faster, improves production efficiency.
Although give some embodiments of the present invention, it will be understood by those of skill in the art that without departing from the spirit of the invention herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of interest field of the present invention.
