Abstract
The invention relates to a balling method for oil shale particles. The technical scheme adopted by the invention is as follows: weighting oil shale particles, adding an organic adhesive which accounts for 1-2wt% of the oil shale and/or an inorganic adhesive which accounts for 1-3wt% of the oil shale into the crushed oil shale, mixing evenly and balling the mixture in a ball machine. The organic adhesive is one or both of carboxymethyl cellulose and unsaturated polyester resin; and the inorganic adhesive is one or a mixture of more of light burned magnesium oxide powder, quick lime, bentonite and portland cement. Compared with the oil shale raw ore, the oil shale ball prepared by the method is characterized in that shale oil is prepared in a retort and the prepared heavy oil has the same oil quality. The waste oil shale particles of which the particle size is no more than 3mm are fully utilized, thus resources can be saved and the environment can be protected; and the quality of the prepared shale oil meets the national standard.
Description
Technical field
The present invention relates to a kind of depleted oil shale particle and flour be utilized again, with the oil shale process for sphericizing broken that economizes on resources.
Background technology
Oil shale is that a kind of standing stock are very abundant, but the Mineral resources that also are not widely used, at present just on stream.Oil shale not only can extract fuel oils, but also can refine out synthetic gas and industrial chemicals, and its byproduct can be used as the fuel of circular fluid bed, and the slag after boiler combustion also can be used for porcelain making brick and material of construction etc.But, because oil shale raw ore intensity is low, in exploitation and broken screening process, there is the particle of the granularity≤3mm of total amount 20% to produce, this part particle can't directly enter into gas retort and carry out destructive distillation system oil, and the enterprise that has makees non-system oil and uses in inside, production cost is significantly improved; And most of enterprise directly abandons this part oil shale particle, not only wastes resource and contaminate environment.
Summary of the invention
In order to overcome the above problems, to the invention provides and a kind of depleted oil shale particle and flour are utilized again, with the oil shale process for sphericizing broken that economizes on resources.
The technical solution used in the present invention is as follows: a kind of oil shale process for sphericizing broken: get the oil shale particle, add the organic binder bond of oil shale particle gross weight 1～2% and/or 1～3% inorganic adhesive, mix balling-up in ball press.
Above-mentioned oil shale process for sphericizing broken, described organic binder bond are one or both mixing of carboxymethyl cellulose or unsaturated polyester resin.Preferably, organic binder bond is the mixture of carboxymethyl cellulose and unsaturated polyester resin, and its weight ratio is 1:0.1～50.
Above-mentioned oil shale process for sphericizing broken, described inorganic adhesive are one or more mixing of light-burning magnesium powder, unslaked lime, bentonite or silicate cement.Preferably, inorganic adhesive is the mixture of light-burning magnesium powder, unslaked lime, bentonite and silicate cement, the mixing of its weight ratio 1:0.1～50:0.1～50:0.1～50.
The invention has the beneficial effects as follows: the present invention adopts tackiness agent, and promptly organic binder bond and/or inorganic adhesive mix according to a certain ratio with depleted oil shale particle, suppress balling-up in ball press, and goods enter intensity behind the kiln dried at 60kg/cm
2More than.Product strength height of the present invention, complete processing is simple, and raw ore is not had any destruction, the production process non-environmental-pollution.The tackiness agent that is added does not have influence to former oil-producing technique, adopts the oil shale ball of method of the present invention preparation to compare with the oil shale raw ore, produces shale oil in retort, the heavy oil of producing oily identical.The present invention makes full use of the oil shale particle of depleted granularity≤3mm, has not only saved resource, has protected environment, and meets national standard with the shale oil quality that it is produced.
