Description

Technical field

The utility model is designed for the needs of the chemical industry and the industrial processing of fossil fuels. It relates to devices for the continuous dispersion, emulsification, mass exchange and homogenization of liquid systems of the gas / liquid, liquid / liquid, liquid / solid type, resulting in a homogeneous product. The utility model will find widespread use in energy to produce high quality alternative fuels.

BACKGROUND OF THE INVENTION

A device-cavitator is known for continuous aeration and homogenization, which serves for aeration, dispersion, emulsification and homogenization of systems of type - gas / liquid and liquid / liquid with reduced (up to 50%) peripheral speed of the rotor. The device has a horizontal or vertically positioned working chamber - a process space with a water jacket, which houses a coaxial stator and rotor. Radial pins are mounted on the outer surface of the rotor, respectively the inner of the stator, at certain angular and linear axial steps, with each row of rotor pins arranged concentrically and moving between two rows of stator pins. The stator and rotor pins are cylindrical in shape, with the rotor cut longitudinally along the axis throughout its cross-section and being passable, with the cutting direction lying in a plane perpendicular to the rotor axis, the slit width being up to 60% of the total width of the rotor pin and its length is up to 90% of the active length of the pin. Mechanical and hydraulic tangential stresses, axial tensile deformation and micro-turbulent vortices are generated in the working chamber / 1 /.

The problem with this device is that it does not fully utilize the physics of centrifugal forces, which leads to an inefficient process of fragmentation of the particles of the working fluid components and which reduces the homogenization and restructuring of the products incorporated for processing. The intensity of cavitation is relatively low. The realities of processed materials in specific areas are limited and cannot be used effectively enough to produce clustered alternative fuels.

The technical nature of the utility model

The utility model consists of a working chamber in which a rotor disk is located. The rotor disk is fixedly connected to a shaft. The shaft is camped in a bearing body. A series of cones with a triangular section profile are radially mounted on the surface of the rotor disc bilaterally. Stator disks are located on both sides of the rotor disc. The stator discs are fixed to the carrier flanges that are connected by studs. On the inside of the stator disks are a radial series of cones with a triangular section profile. The rotor disk is positioned relative to the stator disks so that a zigzag workspace is formed when the two surfaces fit. On both sides of the stator disks are incoming power chambers. The clearance between the shaft and the feed chamber is provided with seals. Exit pipes are located on either side of the process space - working chamber. The outlet pipes are fixedly connected by sealing rings to the supporting flanges.

The benefits of the utility model are:

- high efficiency of material processing;

- full use of the physical impact of centrifugal forces to create and destroy caverns. This ensures an efficient process of fragmentation of the working fluid particles and complete homogenization and restructuring of the processed products;

- the finished product is a degradable, homogeneous substance;

- the utility model enables the use of renewable raw materials such as biomass, bio-waste, peat, etc.

Exemplary embodiments of the utility model

The utility model consists of a working chamber in which a rotor disk is located 2. The rotor disk is fixedly connected to a shaft 1. The shaft camps in a bearing body 3. A series of radially arranged cones with a triangular section profile are formed bilaterally on the surface of the rotor disk. 4. On both sides of the rotor disk are located stator disks 5. The stator disks are fixedly fixed to support flanges 6 which are connected by studs 7. On the inside of the stator disks are formed a series of radially arranged cones with a tr. angular section profile 8. The rotor disk is positioned relative to the stator disks so that a zigzag workspace is formed on the fitting of the two surfaces 13. Outlet pipes are positioned on either side of the process space - a work chamber 11. The outlet pipes are connected with sealing rings 12 to the bearing flanges 6.

The essence of the claimed utility model is to use elements to generate radial centrifugal cavitation. It performs continuous conversion of homogeneous and heterogeneous compositions of hydrocarbon feedstocks and coal into liquid restructured hydrocarbon fuel.

The utility model is a rotary machine (Fig. 1) with a double-sided profile rotor located between two stationary profile stators. The processes take place in the space between the stator and the rotor. If the rotor surface is smooth, the change will be permanent and only in the direction of increase. For this to be an effective cavitation process, this condition is not sufficient. For this reason, the rotor surface is designed as a series of radially spaced cones that form concentric cuts with a triangular section profile (Fig. 2) The axis of these cones is the axis of the rotor. The shape of the groove between the rotor and the stators causes a change in the speed of passage of the material, which depends on the angle of the cone and the distance between the rotor and the stator discs. Channel width may vary. At the beginning of the channel, the material is an incompressible viscous fluid. The passage of material through the duct is influenced by three factors: the pressure difference at the beginning and end of the duct; the friction forces due to the viscosity of the material and the centrifugal forces. A spatial profile of the velocity vectors along the section is created; from zero at the stator contact point to zero with the direction of the rotor point considered. The conical configuration of the rotor causes the material to separate from its walls. To change the type of material flow velocity profile, the rotor also contains "outer" cones. In the cross section of the cone, centrifugal forces are in the direction of the rotor. This configuration of the process space causes it to appear in inactive sections, called "caverns" in practice, and to disappear. In the area of the outer cones, due to the separation of the material from the rotor, at certain rotational speeds, such sections also occur. When moving from the "outer" cones to the "inner" cones, which form concentric cuts with a triangular section profile, the resulting "caverns" are destroyed. The processes associated with these phenomena affect the processed material at different levels, nanoparticles, mechanical particles, molecules, chemical bonds, etc.

The utility model is intended to influence the material to be processed in order to change its properties in the desired degree and direction. Its design makes it possible from a technological point of view to conveniently change all parameters of the process space. In the figures shown, the distance between the rotor and the stator is constant. These rotor and stator parts are interchangeable. In this way it is possible to change the section of the channel by the desired function. The centrifugal forces at the "inner" cones tear off the material from the rotor. These forces depend on the rotor speed. Around the "outer" cones, the pressure of the material acts in the opposite direction. The length of the grooves around the cones and the number of shifts is unknown

1441 Material Handling. In ongoing processes, the material cannot be considered as an incompressible fluid. Changing the rotor and stator profiles allows you to achieve the desired results. Also, the construction 5 allows the dependence of the wear of the rotor and stator elements on the amount and the type of material to be treated to be determined.

Cavitator action

Through the pipelines at the entrances of the feeder chambers 9, a dispersion or emulsion mixture is fed for treatment. The rotor shaft 1 rotates the rotor disk 2. The mixture enters the grooves between the "outer" and "inner" cones of the rotor disk 2 and the stator disks 5. With 15 fluid flow from the center to the periphery, the centrifugal force increases and the friction in the walls increases. in the cone ducts, resulting in the destruction of the dispersed fluid particles and the transformation of the mixture to a homogeneous finished product which is a fuel. It is discharged to the user via the outlet pipes 11.
