Description

The utility model relates to the field of equipment for producing liquid composite fuel mixtures using technical glycerin, which can be used, for example, in boiler units.

A known production line for producing a liquid composite fuel containing containers for a solid component of fuel (coal), for a liquid component of fuel (water) and additives necessary to obtain a suspension.

The capacity (hopper) for the solid fuel component is connected to the chopper. Tanks for water, additives and the output of the grinder are connected to the mixer. The output of the mixer is connected with a hydropercussion device, the output of which is connected to a reservoir for storing and distributing the resulting mixture (composite fuel).

The output of the hydropercussion device by the bypass line is additionally connected to the mixer.

During the operation of the line, a solid fuel component (coal) is fed from the hopper to the chopper, where it is preliminarily ground. The crushed component is then loaded into the mixer, where the liquid fuel component (water) and, if necessary, additives are also fed. The mixer mixes the components loaded into it with the formation of a coarse suspension, which is fed to a hydropercussion device in which the fuel components are dispersed, heated and activated until a finely dispersed suspension is formed, which is fed to the storage and distribution tank for consumers. In case it is necessary to re-process the resulting finely dispersed suspension, it is sent not to the tank, but recycled by the bypass line to the mixer for re-treatment, after which it is again fed to the hydropercussion device and then to the tank.

(see RF patent, No. 2185244, Cl. B02C 21/00, 2000) - the closest analogue.

As a result of the analysis of the implementation of the known line, it should be noted that mixing the crushed solid component and the liquid component of the composite fuel and the subsequent preparation of the suspension in the hydropercussion device does not allow to obtain composite fuel of a sufficiently high quality, since the formation of the fuel composition is carried out with insufficient activation of its solid and liquid components That does not allow the fuel mixture to maintain its properties for a long time. The presence in the resulting fuel mixture of mineral ballast inclusions also reduces its quality.

The objective of this group of utility models is to develop a line that provides high quality composite fuel using technical glycerin.

The task is ensured by the fact that in the line for producing finely dispersed composite fuel containing a receiving hopper for a solid fuel component associated with its grinding device, a mixer for mixing the crushed solid fuel component with liquid components, as well as a storage tank for storing and distributing the obtained target product, new is that the line is equipped with a second chopper, choppers are connected in series with each other, one of the choppers is made in the form hammer mill and the input is connected to the receiving hopper, the second grinder is made in the form of a vibro-pulsed parabolic mill, the output of which is connected to the mixer, and the line is equipped with a series-connected disperser-activator equipped with an electromagnetic device for the resulting product, and a cavitator, the output of which is connected to the storage tank and the input of the dispersant-activator is connected to the output of the mixer.

When conducting patent research from the prior art, no solutions were identified that are identical to those disclosed in this application, and therefore, the claimed group of solutions meets the eligibility condition “novelty”.

The information set forth in the application materials is sufficient for the practical implementation of the group of utility models.

The essence of the claimed utility model is illustrated by graphic materials on which a diagram of the line for producing finely dispersed composite fuel is presented.

The line for producing fine composite fuel contains a receiving hopper 1 with a feeder (not shown) for the solid component of the composite fuel (for example, raw coal). The output of the receiving hopper 1 by means of a feeder (for example, auger) is connected to a coal grinder 2. As a grinder, a standard hammer crusher is used. The output of the hammer mill 2 is connected to the inlet of the second grinder 3. A vibratory parabolic mill is used as the second grinder. The designs of such a grinder are known.

The output of the second grinder is connected to the input of the mixer 4. The mixer 4 is equipped with additional inputs for supplying water and technical glycerin. Water and industrial glycerin can be piped from storage tanks (not shown). Water can also be supplied directly from the water supply system, and technical glycerin directly from the technological module for its production (not shown).

The output of the mixer 4 is connected to a dispersant-activator 5, equipped with an apparatus 6 of electromagnetic influence (for example, an electromagnetic vibrator, with a power of not more than 300 W).

The output of the dispersant-activator 6 is associated with a cavitator 7, for example, hydropercussion, the output of which is associated with a tank 8 for collecting the target product.

All units and nodes of the line, as well as their transport systems are known, they do not constitute the subject of patent protection and therefore are not disclosed in the materials of this application. Naturally, to move the components of the mixture in the process of obtaining fuel in the installation, pumps, pipelines and other fittings are used, the implementation of which is known.

The line for producing finely dispersed composite fuel operates as follows.

In the hopper 1, pre-crushed raw coal (solid component of composite fuel) pre-crushed to a particle size of not more than 250 mm is loaded. From the hopper 1, coal is dosed by a feeder for grinding. In hammer mill 2, coal is crushed with a crusher size not

more than 10 mm, and in a vibratory impulse parabolic mill - not more than 300-600 microns.

The coal crusher from the grinder 3 is fed into the mixer 4, which also serves water and technical glycerin (for example, a by-product of the production of biodiesel motor fuel and various combustible waste). The ratio of the components of the mixture can be different, for example: coal - 50-60%; water - 20-25%; technical glycerin - 20-25%. From the output of the mixer, the suspension obtained in it is fed to a dispersant-activator 5, where the solid component is regrind to a fragment size of not more than 100 μm, and the suspension is mechano-chemically activated with electromagnetic influence on it.

Further, the raw material enters the hydrocavity cavitator 7, where the final grinding of the solid component and the destruction of the liquid to a size of not more than 1 μm are carried out.

In the cavitator, grinding is carried out by means of shock-shearing effects on crushed particles, which are broken into fragments with their simultaneous deformation. Deformation causes the appearance of mechanical and thermal stresses, electrostatic fields on these particles and an increase in chemical activity on the outer surface and in the pores of the particles. An increase in the internal energy of particles due to these phenomena caused by the specifics of their grinding makes up from 10 to 30% of the impact energy.

A large number of highly reactive radical particles are formed in the liquid.

The liquid is saturated with hydrogen peroxide molecules and hydroxonium ions, which are powerful oxidizing agents, providing the initiation and occurrence of many chemical reactions, including the oxidation of organic compounds.

The finely dispersed composite fuel obtained in the manner described above from the unit 7 enters the consumable container 8, from where it is issued to consumers.

The line disclosed in this application provides the production of composite fine fuel with an increased (50-60%) solid component content, which provides a heat of combustion of up to 4225 kcal / kg of fuel.

The ash content does not exceed 3-4%.

The maximum content of harmful impurities when burning the resulting fuel:

- on dust - not more than 10 mg / m3;

- СО - no more than 50 mg / m. cube;

- NO - not more than 200 mg / m. cube;

- SO - not more than 50 mg / m. cube
