Description

Description of the invention

A useful model concerns the processing industry, in particular the processing of agricultural waste, the 2nd can be used for the production of environmentally friendly fuel briquettes for energy use in production and household use.

The prototype of the proposed useful model is a method of manufacturing environmentally friendly fuel briquettes

Patent of Ukraine MobO596, Cl.S101I 5/40, publ. 2006 | from organic raw materials (reed straw, forest and wood industry waste), activated carbon in the form of dust and pine flour as a binding additive, which 70 includes drying, grinding to fractions of no more than 1 µm, mixing of components and pressing at a pressure of 1000-1500 kg/cm into cylindrical briquettes.

The presence of pine flour as a binding additive, which contains resinous substances, with this method of making briquettes, ensures their long-term shape stability, density and compressive strength, such briquettes have a high calorific value. However, this method can be improved to reduce the cost of 12 briquettes.

The basis of the useful model is the task of improving the method of manufacturing environmentally friendly fuel briquettes in order to reduce their cost.

The task is achieved by the fact that in the method of manufacturing environmentally friendly fuel briquettes from organic raw materials, which includes drying the raw materials, grinding them to fractions of no more than 1O0μm, mixing the components and pressing them at a pressure of 1000-150Okg/cm into cylindrical briquettes, according to a useful model, as an organic sunflower husks, biomass waste from the sugar industry and waste from biodiesel production are used as raw materials.

The introduction of various components of biomass into briquettes, namely sunflower husks, waste from the sugar industry and waste from biodiesel production, does not require the addition of binding components, but only their grinding to a fraction of at most 1µm and compression. This method ensures long-term shape stability of the briquettes, their sufficient density and compressive strength, the briquettes do not crumble and have a high calorific value. Grinding the components into flour gives uniformity to the structure of the briquette, which ensures even combustion.

The method is carried out as follows. at

Organic raw materials are dried to a moisture content of no more than 895, ground to a fraction size of no more than 1µm and F) thoroughly mixed. The prepared mixture is loaded into a pressing cylinder with a diameter of 8 mm and a height of 400 mm and pressed with a force of 1100-1500 kg/cm2. A cylindrical shaped briquette with a density of 1-1.2 g/cm3U and a weight of 500-800 g depending on the bulk density of the mixture is obtained. Calorific value of the obtained briquette is 23-28 mJ/kg, ash content - 0.5-2.590. high school

Experimental fuel briquettes were produced by the proposed method with different content of components, and research was conducted on calorific value depending on the type of organic raw material and specific heat capacity depending on the internal structure of the briquette - density, porosity.

As a result of experiments conducted to determine the calorific value of fuel briquettes in "20 depending on the type of organic raw materials, the values presented in the table were determined. w-in

As a result of experiments conducted to determine the specific power of fuel briquettes depending on the internal structure, it was established that the size of the fractions of the components significantly affects the thermal power, in particular, the smaller the size of the fractions, the higher the thermal power. For example, for a mixture of З0О96 pulp, З090 meal from biomass and 4095 sunflower husk, the calorific value is: for the size of fractions up to 4Ωm 9.2-9 AcW/kg; o for the size of fractions from 4Ωm to 400μm 7.5-8.1kW/kg; 1 for the size of fractions greater than 40О0μm 6.1-6.7kW/kg. b Similar trends (decrease in thermal power by 15-179o with an increase in the size of fractions by an order of magnitude) (Te) 20 are also observed with other variants of mixtures. In addition, grinding the component briquettes into small fractions before pressing significantly improves the consumer characteristics of fuel briquettes, namely increases its density, shape stability and strength. With the size of fractions up to 40 μm, the consumer characteristics of fuel briquettes are as follows: 52 ash content 0.5-2.595; c density 1100. 20Okg/m Z; burning with a torch. in (o) production (95) yuyu vv nn nin nyny
