Description

Technical field

The technical solution relates to the composition of a biodegradable mass of waste materials of primary biological origin containing biogenic elements carbon, hydrogen, oxygen, sulfur and nitrogen, intended for the production of direct combustion fuel, located for starting the production process in aerobic atmospheric atmospheres. It also relates to a process for the production of fuel from a biodegradable mass of waste materials of biological origin.

Prior art

Several methods are currently known for disposing of or recovering waste materials of biological origin. The best known is composting, which is an aerobic process of decomposing material of usually vegetable origin, taking place under certain conditions with the contribution of microorganisms. The resulting product is usually used for fertilization or as part of a substrate for growing plants. The disadvantage of this process is that no harmful substances, for example petroleum substances, drug and drug residues, hormones, heavy metals, endocrine disruptors, poisons, dyes, etc., are removed from the starting mass.

In nature, also in the long-term process, the so-called charring (or ulmification) of a mass of plant material, which results in a combustible material such as peat or coal. However, due to the very long process, it is difficult to use for the practical use of bio-waste disposal.

There is a continuing need to dispose of or use bio-waste, substances in their original form that are difficult to use and hazardous or hazardous substances. A process of chemical-biological heating appears to be suitable, which should result in an easily combustible mass with a significant calorific value and good fuel properties. However, the start-up and intensity of the process is highly dependent on the chemical, biological and physical properties of the starting mass. This seems to be a significant problem, because with an inappropriate composition of the mass, the process does not take place with the desired intensity or appropriate extent.

The task of the technical solution is to create such a composition and properties of the starting mass of waste materials of biological origin and to create such conditions that the process of chemical-biological heating can be started spontaneously and with sufficient speed, resulting in material with pollutants neutralized or disposed of, with high energy value , usable as a fuel for direct combustion.

The essence of the technical solution

This task is fulfilled by a technical solution, which is a mass of waste materials of biological origin and biodegradable, containing biogenic elements carbon, hydrogen, oxygen, sulfur and nitrogen, for the production of direct combustion fuel, located in an aerobic environment in the presence of atmospheric oxygen and other atmospheric gases. . The essence of the technical solution lies in the fact that the meat contains a starting moisture of 40 to 70% by weight. of water and at least 25 wt. organic matter, where the total weight of the mass is at least 3 000 kg and is piled up to a height of max. 3 m into a formation with a vertical axial cross-section in the shape of an isosceles or equilateral triangle, or trapezoid, or rectangle. The meat consists of at least two basic groups of substances, on the one hand juicy substances with a water content of 5 to 98% by weight, as a source of microflora and water inoculum, and on the other hand juicy substances in an amount of at least 15% of the total weight of the meat as a source of reducing agents and structural substances . By juicy substances is meant at least one kind of sludge substance which consists of a liquid phase and a solid phase dispersed in the liquid phase. By juicy substances are meant cellulose-containing materials with a fraction of 15 to 750 mm Juicy substances are sludges from municipal wastewater treatment plants and / or sludges from industrial wastewater treatment plants, and / or materials of a less sludge character. Non-juic substances are ligns of cellulosic materials and / or packaging and their parts of the commercial and / or municipal sphere, and / or other cellulose-containing materials.

It is also important for the technical solution that the sludge from municipal wastewater treatment plants is selected from the group of sludges: primary sludge, secondary sludge, tertiary sludge, raw sludge, anaerobically stabilized sludge, aerobically stabilized sludge, chemically stabilized sludge, physically stabilized sludge and dewatered sludge. Sludges from industrial wastewater treatment plants are selected from the group of sludges: sludges from pulp and paper production, sludges from plywood production and waste fibers from fibreboard production, manure, excrement, bedding and sludges from other production. Materials of less sludge character are selected from the group of materials: carcasses, silage, silage, fruits, vegetable fats and oils, residues from agar and gelatin production, nutrient soils from biotechnological production, products from biogas plants, aquatic plants and animals, wastes and surpluses from food.

S K 8302 Y1

The lignocellulosic materials are dendromas and / or phytomases. Packaging and parts thereof from the commercial and / or municipal sphere are selected from the group of materials: paper, cardboard, cardboard, beverage and food packaging from combined materials, such as tetrapacks. Other materials are selected from the group of materials: banknotes, pulp products.

It is also essential for the mass of waste materials according to the technical solution that in order to achieve the maximum effect it is essentially piled up in a pyramidal formation with a ridge or top height of at least 1.5 m and a maximum of 2.5 m, with a total mass exceeding 3,000 kg. preferably over 10,000 kg.

It is suitable if the meat contains 50 to 65 wt. % water.

At least some of the juicy substances can be replaced by auxiliaries, such as a reaction area-increasing agent and / or a thermal insulating agent. These auxiliaries consist of lignocellulosic auxiliaries and / or mining sludges and / or mining sludges, and / or other wastes. selected from the group of materials: sawdust and shavings, straw pulp, cubes, fruits and their parts and shells, husks, powders, bran, grass, aqueous biomass, and other waste is selected from the group of materials: bottom sediments, rubber products, leather waste.

The essence of the method of fuel production from waste materials of biological origin is that the individual components are deposited in layers under normal atmospheric conditions to form a mass, the individual components being selected and / or replenished according to the moisture content, with the starting moisture of the mass being 40 to 70% by weight mass, and with the result that the resulting flowability of the mass allows the designed shape to be maintained independently. Subsequently, they are mechanically mixed to a homogeneous composition and to an even distribution of moisture and accumulated as meat into a formation with a maximum height of 4 m, which after settling drops to the required height of 3 m. The surface drying of the mass associated with mass escapes is monitored. the meat is mechanically and / or pneumatically mixed and homogenized again. At the same time, leaks of leachates from the lower part of the mass are monitored, where when leachates form, due to excessive settling or moisture seepage into the lower layer, the meat is mechanically and / or pneumatically mixed and homogenized again. At the same time, the temperature development in the area of at least 0.8 m above the base and at least 0.8 m below the surface of the mass is monitored, while in case of premature temperature stagnation the mass is repeatedly mixed, ending the process after stopping temperature fluctuations at stable temperature of maximum 40 ° C. .

The advantage and higher effect of the technical solution is not only to obtain a fuel with a significant calorific value, but especially to neutralize and / or decompose the pollutants present in the feedstock. During the process of chemical-biological heating and conversion of starting substances and subsequently during controlled combustion of the final substance - fuel, the vast majority of undesirable substances are finally and completely eliminated. This minimizes their impact on the environment and, in addition, provides usable fuel for direct combustion.

Examples of embodiments

Before describing several examples of the specific composition of the mass according to this technical solution, the basic characteristics of the chemical-biological heating process will be given.

A mass of materials with certain biological, chemical and physical properties must be created to start the process on its own. Mass, resp. its components are of biological origin and biodegradable, containing the biogenic elements carbon, hydrogen, oxygen, sulfur and nitrogen. Materials do not have to be precisely defined, but must meet certain parameters. Important for the process itself are in particular:

- content of organic and inorganic constituents,

- chemical and biological properties of the ingredients,

- percentage of individual components,

S K 8302 Yí

- the bound and free moisture content of the meat,

- particle size,

- percentage of smaller and larger particles,

- total volume and shape of the mass,

- bulk density,

- porosity,

- thermal insulation properties of the mass,

- gas concentration,

- the duration of the process, and - the ambient conditions.

During the process, the bonds in the components are thermally cleaved and their chemical composition is changed to form other substances. The structure and construction of materials change depending on the size of the pores and capillaries that affect the transfer of oxygen, heat and gas permeation. Ongoing processes are also affected by particle shapes and sizes, such as dimensions, number of edges and rounding, and different angles on the particles. The process is faster and more intense for materials with a rough and porous surface than for materials with smooth particles. Thermodynamic properties are also important, such as mass and heat capacity of materials, thermal conductivity, heat transfer coefficient, etc.

It is essential for the technical solution itself to create suitable conditions for starting and maintaining the said process. This is achieved by appropriate composition of the mass and ensuring its important parameters.

The process begins immediately or after a very short time from the formation of the base mass, first in the individual deposits, which gradually increase and spread throughout the mass. The process takes place automatically in individual phases, it evolves over time. Given that the very nature of the process of chemical-biological heating cannot be the subject of a technical solution, its detailed explanation is not important here.

However, it is important to ensure that the process runs efficiently, or what steps to take to achieve process optimization. This requires:

1. Monitor the composition of the mass with a total organic matter content of at least 25% by weight, preferably above 35% by weight.

2. To achieve the correct chemical and biological properties of the mass by consisting of two basic groups of substances, on the one hand juicy substances 1 with a water content of 5 to 98% by weight, as a source of microflora and water inoculum, and on the other hand juicy substances 2 in at least 15% total weight mass, but preferably above 25% by weight. masses as sources of reducing agents and structural substances. A part of the non-juicy substances 2 can be replaced by auxiliaries 3, as an agent for increasing the reaction area and / or a thermal insulating agent, i.e. for optimizing the physical properties of the mass.

3. Achieve an initial moisture content of the mass after mixing before starting the process of 40 to 70% by weight. of water, preferably 50 to 65% by weight.

4. Securing and maintaining as much of the thermal energy generated as possible, which varies at different stages of the process. However, the rule is that ambient cooling must be lower than heating due to the ongoing process. The ideal process development occurs when the temperature rises to about 50 to 55 ° C within 72 hours of the formation of the set, and / or when the temperature rises by 5 to 7 ° C in 24 hours. The highest intensity of the process occurs at a temperature above 60 ° C. It is desirable that the temperature of the mass exceeds 60 ° C within 96 to 120 hours from the formation of the mass, because under these conditions the optimal course of individual events takes place. As the temperature of the mass increases, the rate and intensity of the reactions increase. As the temperature increases by 10 ° C, the reaction rate increases 2 to 4 times.

5. Ensure the correct amount of oxidizing and reducing agents in the meat. Oxidizing agents induce and maintain the process, reducing agents oxidize during the process. It is characteristic of this technical solution that it uses the most available oxidizing agent, which is atmospheric oxygen. It is desirable to form in admixture with other atmospheric gases about 21% by volume of the gaseous component of the mass. The porosity and bulk density of the mass, its shape and height, as well as the size of the individual fractions, the ratio of larger and smaller particles, the diversity of particle shapes must be adapted to maintain the amount of atmospheric oxygen in the meat. A larger number of small particles increases the area for the reaction, larger particles ensure the porosity of the mass.

6. Adjust the size, structure, shape and amount of particles before mixing the starting mass mixture. It is important for the course of the process that its physical properties are ensured and maintained in particular. The minimum weight should be at least 3,000 kg, but preferably more than 10,000 kg. The ideal shape of the piled-up mass for maximum effect is essentially a pyramidal saddle with a ridge height or apex of at least 1.5 m and at most 2.5 m, with a vertical axial cross-section in the shape of an isosceles or equilateral triangle, or less preferably in the shape of a trapezoid or rectangle. Such a shape and weight of the mass ensures sufficient passage of atmospheric gases, there is no excessive lightening of the mass, while maintaining the desired bulk density and porosity of the mass and its thermal insulation properties. Ideally, a layer of 1.5 to 2.5 m generally insulates the emerging bearings of the self-heating process very well. To achieve maximum

With the K 8302 Yí effect, the layer should not be higher than 3 m.

It should be noted that in many cases it is appropriate to remove the gases formed, in particular NH3, H2S, CO2 and CH4, or to promote their escape, in order to optimize the process, as they may have a negative effect on the transformation processes.

When regrouping the mass, it is possible to add other substances to improve the parameters to positively influence the process, speed it up and make it more efficient.

The end of the process is manifested by a spontaneous reduction of the temperature of the mass, a change in the original humidity, structure and appearance.

For the groups of substances listed in point 2:

There are practically three groups of substances, namely juicy substances 1, non-juicy substances 2 and auxiliary substances 3.

Juicy substances j are at least one type of sludge substance which consists of a liquid phase and a solid phase dispersed in the liquid phase. These are sludges from municipal wastewater treatment plants 1a and / or sludges from industrial wastewater treatment plants 1b, and / or materials of a less sludge character 1c.

Sludges from municipal wastewater treatment plants 1a are selected from the group of sludges: primary sludge lacquer secondary sludge la2. tertiary sludge la3. raw sludges la4. anaerobically stabilized sludge la5. aerobically stabilized sludge la6, chemically stabilized sludge la7, physically stabilized sludge la8 and dewatered sludge la9.

Sludges from industrial wastewater treatment plants 1b are selected from the group of sludges: sludges from the production of pulp and paper Ibb sludges from the production of plywood and waste fibers from the production of fibreboard ľb2, manure, excrement, bedding lb3 and sludge from other production lb4.

Materials of less sludge character 1c are selected from the group of materials: carcasses, silages, silages 1cL fruits lc2, vegetable fats and oils lb3, residues from the production of agar and gelatin lc4, nutrient media from biotechnological production lc5. products from biogas plants lc6, aquatic plants and animals lc7, waste and surpluses from food lc8.

The non-juic substances 2 are cellulose-containing materials with a fraction of 15 to 750 mm. These are a league of cellulose materials 2a and / or packaging and parts thereof from the commercial and / or municipal sphere 2b, and / or other cellulose-containing materials 2c.

Lignocellulosic materials 2a soudendromase 2a and / or phytomase 2a2.

Packaging and their parts from the commercial and / or municipal sphere 2b are selected from the group of materials: paper 2BL cardboard 2b2. cardboard 2b3. beverage and food packaging 2b4 of composite materials, such as tarpaulins.

Other materials 2c are selected from the group of materials: banknotes 2cL pulp products 2c2.

The other components 3 are lignocellulosic material 3a and / or mining, and / or mining sludge 3b, and / or other waste 3c.

The lignocellulosic auxiliary material 3a is selected from the group of materials: sawdust and shavings 3a1, straw pulp 3a2, cubes, fruits and their parts and shells 3A3, husks, powders, bran 3a4, grass 3a5 and aqueous biomass 3a6.

Other waste 3c is selected from the group of materials: bottom sediments 3cL rubber products 3c2, leather waste 3c4.

All materials should be suitably treated before mixing into the mass. The juicy substances 1 are usually subjected, if necessary, to drying or drying, sedimentation or other kind of separation of components, dewatering, sterilization or pasteurization, etc. The non-juicy substances 2 are usually mechanically treated, crushed, split, cut, ground and sorted. The excipients 3 are modified according to their nature chemically and / or mechanically, for example by drying and drying, dewatering, separation, hygienization, etc.

After treatment, the individual components are weighed, dosed and mixed into a relatively homogeneous bulk mass. It accumulates in the appropriate stated shape of a pyramid or saddle shape with a ridge line. Under normal atmospheric conditions, the desired process is started practically within a few hours, if the composition and parameters of the mass are according to the technical solution.

During the process, it is possible to control parameters such as humidity and temperature, or the presence of various gases, etc. If necessary, or to speed up the process, it is appropriate to rearrange the meat, mix it, or add it to adjust the parameters of another substance. The result is a combustible mass - a fuel with a good calorific value, which can be burned directly for the subsequent production of heat or electricity. The whole process is characterized by a synergistic effect in obtaining the energy potential of the mass. The calorific value of the final fuel is higher than the sum of the calorific values of the input materials.

The handling of the meat and the process of its formation in practice is usually such that the input components, in which at least 80% by weight of the final mass consists of fractions of 750 mm maximum, are piled up to a pile of 4 m high, which after homogenization by mixing and settling obtains the required height max. 3 m. The advantage of a triangular or trapezoidal vertical cross-section of the mass lies in the fact that air is sucked in from the surrounding environment to the base of the mass. As the air passes through the core of the mass, the air is intensively heated and the heated one emerges and escapes through the top of the mass, thus achieving movement in the meat.

When creating an assembly, the components are combined and stacked on top of each other. The total humidity is monitored with respect to the fact that the resulting starting mass is 40 to 70% by weight. mass. The resulting flowability of the mass is also monitored, which allows the designed shape to be maintained independently. The components are mechanically mixed to a homogeneous composition and to an even distribution of moisture and piled up as a mass into a formation. If the formation is sufficiently homogeneous after the layering of the components and retains its shape due to the appropriate flowability, mixing is not necessary. Self-holding of the shape is a sign of the correct mechanical composition with suitable humidity. The surface drying of the mass associated with the mass escapes is then monitored, where the mass is mechanically and / or pneumatically mixed and rehomogenized during the resulting escapes. Spills occur when the meat on the surface is too dry. Leaks of leachates from the lower part of the meat are also monitored, where when leachates are formed, due to excessive settling or leakage of moisture into the lower layer, the meat is mechanically and / or pneumatically mixed, homogenized and moisture is distributed throughout the volume, the meat is also aerated and oxygen is added, which is intensively consumed in the process. Excessive settling, possibly by moisture-soaked bottom layer, would reduce the gaseous component required for the process. At the same time, the temperature development in the area at least 0.8 m above the base and at least 0.8 m below the surface of the mass is monitored. The temperature must be measured regularly, optimally daily, or continuously with special probes. The basic monitored parameter is the constantly rising temperature trend. It doesn't matter how fast the temperature rises, but it has to rise. The increase in temperature is not infinite, but if stagnation or a decrease in temperature is observed, the meat must be mixed again. This automatically cools the mass, but the temperature rises again due to the ongoing reactions. In this way, the meat is repeatedly heated and cooled to produce a typical tooth-like temperature profile. At the beginning of the process, the changes are very significant, but over time they decrease and the fluctuations become flat, which is a typical feature of the gradual depletion of usable energy. Normally, temperatures above 55 ° C are reached during the process, ideally temperatures above 70 to 75 ° C rise, thus hygienizing the mass.

By repeated temperature rise and subsequent cooling, which is ensured by mechanical and / or pneumatic stirring, appropriate values for the operation of the process can easily be achieved: - oxygen content in the gaseous component of the mass does not fall below 12% by volume of the gaseous component, - CO2 content in the gaseous component of the mass does not 30% by volume of the gaseous component, - the nitrogen content of the gaseous component of the mass does not exceed 25% of the volume of the gaseous component, - the moisture in the meat is uniform throughout the volume, and

- due to the structure, air pockets are created, in which the most intensive reactions take place.

If the temperature does not rise above 40 ° C after repeated mixing during the measurement, this is a sign of depletion of the usable energy for the processes in the meat and the process ends. In that case, the meat has reached the peak of its potential and can be used as fuel. It is not necessary to always wait for this state to be reached, the process can be terminated sooner, but the properties of the fuel will be worse.

This fuel can be sorted, crushed, used to add other additives to improve the parameters, or dried and granulated, extruded, etc. before use. Depending on the nature of the input substances, especially with regard to the pollutants contained in them, an analysis is performed to control the chemical and physical properties of the fuel and to control the removal of pollutants, ideally their complete degradation to health-friendly substances.
