摘要

A method of processing kaustobolite coal (especially lignite and leonardite) into humic organic and organic mineral fertilizers and materials by forming fuel briquettes. The process is carried out on a continuous stream with a basic process; Application of leaching process based on aqueous solution in Hydromodule 2, application of acidification process by extracting humic acid from liquid phase to solid phase (pulp coagulation), application of mechanical separation process in centrifugal field, application of mechanical activation of liquid phase and process application of dispersing the reaction composition by friction, Residual wastewater is used in recycling, ensuring a wide line of products to produce water-soluble humic acid and fuel briquettes. Grind the raw material to 0-3mm grade in advance; Application of liquid phase acidification process and liquid phase mechanical activation and/or mechanochemical activation process of raw materials by dispersing the static parameter of the shear rate of the solution processed from several meters to several tens of meters per second and the reaction solution due to friction or dynamic shear of the layer; perform cleansing and electrochemical water softening to produce a reaction aqueous solution; Stabilization of the feeding process and the supply of mechanical energy (10 to 40 MJ per square meter) to the solution, regardless of the drift of other parameters of the solution being processed during this mechanical activation process; Dynamic impact (hydraulic pulse impact) on the solution being processed is carried out within the floating range from ultrasonic to low frequency; In this case the treatment process is carried out starting with a higher frequency; To prevent the mechanochemical reactor from moving into cavitation mode, it automatically maintains the maximum parameters to supply mechanical energy with automatic limiting function in the non-cavitating zone. A mechanochemical reactor that processes unusually high-viscosity solutions, including suspensions and pulps, is designed based on a classic rod mill. The reactor consists of a grinding chamber, internal rotor and rod openings, and an impact rod and drive. The grinding chamber has no mechanical connection with the drive of the rotor, so it is equipped with a rotary cleansing device with a magnetic drive. The cleansing device is designed in the form of a rotating miniature rotor equipped with a cleansing rod; since the cleansing miniature rotor is installed in the plane of one of the working rotors, the rotating axis of the miniature rotor is located in an arc that is part of a concentric circle of the working rotor. In this regard, a small rotor is positioned around the working rotor with an approximate distance between the cleansing rod and the bars of the actuating rotor (the rods come closest to each other when actuating and rotating the cleansing rotor); Considering the rotational direction of the small rotor, the pulling force on the cleansing rod in the peripheral flow of the solution being processed is in the direction that the peripheral flow up to the rod port rises compared to the cleansing rod due to the frictional force of this solution. So ensuring the most effective cleaning of the reaction volume of the half vessel; A classic hydropuller is used in the space between the rotor disk and the reactor housing to prevent centrifugal forces from acting on the solution being processed; The hydraulic puller does not enter the gap between the rotor and the reactor housing to ensure that the solution being processed is supplied to the reaction chamber. The rod of the actuating rotor is positioned at a radial distance from the rotor axis of rotation so that the diameter of the rod is increased. The number of rods in each row is the same; The process of supplying the high-viscosity solution to be processed to the reaction chamber is carried out by means of two screw channels; The radial feeding of the solution to be processed to the active area is carried out by means of a built-in pump blade; the possibility of controlling the feeding by means of an autonomous channel of a second liquid component of the solution being processed; The main working drives of the reactor (rotating working rotor and the drive feeding the solution to be processed) are adjustable in speed and are functionally interoperated by a dedicated controller to ensure an optimal mode of processing the reaction composition;
