Comprehensive conversion method of lignite and leonardite to humus fertilizer, preparation to briquette fuel, and mechanochemical reactor for high viscosity medium conversion
The process of comprehensive conversion of mostly brown coal and leonardite coal-based combustible biologic rocks to humic organic and organic mineral fertilizers and to briquette fuel preparations is a basic process of continuous flow: Using leaching based on aqueous solutions with a duty of water curve of about 2, using oxidation with drawing from liquid phase to heavy phase (agglomerated slurry), mechanical phase in centrifugal field Perform steps using separation, using liquid phase mechanical activation and dispersion of the reaction composition by grinding, and using recycled residual “water” to obtain water soluble humic acid and briquette fuel In the process, the raw materials are previously added in order to produce a wide range of products. . . Water is refined and electrochemically softened to prepare a reaction aqueous solution, ground to 3 mm grade; raw material liquid phase oxidation process is applied, and the medium to be converted is several to several tens Liquid phase mechanochemical activation and / or mechanochemical activation with dispersion of the reaction composition by friction and dynamic shearing of said phase with a drift velocity of m / sec is applied; this mechanochemical activation is With the introduction of energy reduced to 10-40 MJ / m3 to the medium, this metric is stabilized despite drift of all components in the medium to be converted; where defined friction and shear processes Is formed by means of static and dynamic features; for example, the medium in which dynamic (hydraulic impulse) impacts in the frequency range from near infrared to very low frequencies to the frequency of the ultrasonic boundary are converted. The conversion defined here is also initiated using a high frequency; where the automatic maintenance management of the maximum parameters of mechanochemical energy introduction into the medium to be converted is the cavitation of the mechanochemical reactor. It is secured by automatic restriction in the subcavita
