The method of complex processing of brown coals and leon- dite into humic fertilizers, preparations and into fuel briquettes and mechanical reagent of high-grade media

摘要

The method of complex processing of caustobioliths of the coal series, mainly brown coal and leonardite, into humic organic and organic fertilizers and into preparations with the production of fuel briquettes, including carrying out the main processes in continuous flows; the use of leaching processes based on aqueous solutions with a hydromodule of about 2, the use of acidification processes to form the release of humic acids from the liquid phase to the heavy phase - coagulated pulp, the use of mechanical phase separation processes in a centrifugal field, the use of liquid-phase mechanical activation and dispersion of the reaction compositions by grinding, using residual "water" in recycling and involving the production of water-soluble humic acids and fuel briquettes and ensuring the production of shea Oka product line; carry out preliminary grinding of raw materials to a class of 0-3 mm, and for the preparation of the reaction aqueous solutions carry out cleaning and electrochemical softening of water; apply the process of liquid-phase oxidation of raw materials and apply liquid-phase mechanical activation and / or mechanochemical activation with dispersing the reaction compositions by grinding and dynamically shifting the layers with static components of shear rates from units to tens of meters per second of the medium being processed, accompanying this mechanical activation by metered introduction of mechanical energy into this medium 10-40 MJ per cubic meter with the stabilization of this dosing is not dependent on the drift of all other parameters in this processable medium; however, the above processes of grinding and shear form by means of static and dynamic characteristics; so dynamic - hydro-impulse effect on the processed medium is carried out in the range of floating frequencies from infrasound to borderline frequencies with ultrasound, with the above-mentioned processing in time carried out, starting with higher frequencies; at the same time, they also provide automatic maintenance of maximum parameters for the input of mechanical energy into the processable medium with its automatic limitation in the subcavitational zone in order to prevent the mechanochemical reactors from “stalling” into cavitation modes.
