Abstract

PROBLEM TO BE SOLVED: To provide a method for storing carbon, nitrogen, minerals and the like of organism waste in order to circulate into soil, instead of embedding, composting or burning.SOLUTION: Waste is treated by "a low oxygen circulation system with sealed hot air" composed of a combination of a drying kiln, a condenser and a hot blast stove and by a process of "scenting-condensation-carbonization". Waste is feed to a drying kiln for scenting drying, sterilization deodorizing, solid separation and mineralization, and then vaporized liquid in a discharged gas of the kiln is collected by condensation by a condensation device to obtain vinegar liquid of organisms. The scented dried products produced from the kiln are classified into organisms and artificial products, and the former ones are scented organisms storing carbon and nitrogen and can be refined into scented organism fertilizer or carbon nitrogen agent. The latter ones are carbonized in the hot blast furnace. Hot air generated is once again sucked into the drying kiln, and successively transportation of heat and substances is performed. Zero emission of dioxin and gas by green house effect is achieved. Since nutritional elements in organism waste can be returned 100% to soil, substances can be circulated and soil can be enriched, and further the amount of organic carbon in soil can be increased.

Description

  The present invention touches on nutrient element storage and circulation technology and equipment in “organism (biomass) waste”. The biological waste mentioned here refers to biological waste in food waste, food processing, agriculture, forestry, and fishery waste, livestock poultry manure, sewage sludge, etc. (hereinafter referred to as `` garbage '' or `` biological waste ''). ). That is, this is also a new method for waste disposal such as garbage and sewage sludge. The present invention touches on technical fields such as ecology, biology, environmental science, soil science, plant nutrition fertilizer science, chemistry, thermology, waste treatment, and biomass energy.

  Let's look at the current state of garbage disposal as an example of biological waste disposal. Currently, there are three main types of garbage disposal: landfill, composting, and incineration (power generation). In the case of landfill, in addition to occupying a large amount of land, it produces a foul odor, leaching the filtrate, and generating greenhouse gases such as methane gas CH4 and carbon dioxide CO2. In the case of compost, greenhouse gases such as methane and nitrous oxide N2O are also generated, and it is difficult to produce high-quality fertilizers, and the volatilization loss of carbon and nitrogen is large. The incineration process artificially causes carbon and nitrogen in organisms that should be returned to the soil to be “short-circuited” and volatilized. As a result of large-scale incineration, emission pollution such as carbon dioxide and nitrogen oxides and resource loss occur, and carcinogenesis occurs. Dioxin, which is a chemical substance, is also likely to occur. This may be a serious “error” of humanity. Furthermore, although this process requires a very high cost, the reduction rate to energy is low. Since this conventional garbage incineration process has conditions for generating dioxins, the amount of dioxins contained in the exhaust gas is relatively high, and 90% of the dioxins in the atmosphere are from incineration. Dioxin damage is already serious in the country or region where waste incineration has been promoted. For this reason, landfilling, composting, and incineration (power generation) methods each have fatal harmful effects, and none of them can achieve harmless treatment, and are not ideal treatment methods.

  Ever since advanced countries turned from incineration to incineration, they are skeptical about the “advancement” of waste incineration technology due to the emergence of fatal hazards such as dioxins. On the other hand, landfilling is still the mainstream in developing countries, but incineration is increasing year by year, and the “incineration” business is developing while controversial over the “merits” of this treatment. Undoubtedly, traditional incineration continues to develop, and as a result, dioxins are doubling, trying to significantly destroy the ecological environment of our planet and our living environment. This is exactly the greatest crisis caused by the development of human society, the ecological disaster.

  In the technical problem of waste incineration, there are two undesirable things we consider.

  First, it is not desirable to burn. Not only is it wasteful to “incinerate” biological (biomass) waste, but it also generates greenhouse gases and harmful exhaust gases. When incinerated, nutrient elements such as carbon and nitrogen in biological waste are not returned to the soil, but are converted into greenhouse gases, harmful exhaust gases, water vapor, etc., and discharged into the atmosphere. A “short circuit” loss occurs. If incineration continues, it will be difficult to solve problems such as deterioration of material circulation in ecosystems, reduction of soil organic carbon storage, reduction of soil fertility, and global warming.

  Second, wet incineration is undesirable. Dioxins are likely to occur during the wet incineration of garbage. The conventional waste incineration method is wet incineration, and the drying and combustion processes are performed in the same incinerator. Since the garbage contains a lot of water, it leads to a decrease in the temperature in the incinerator at the beginning of drying and combustion, and incineration at 800 ° C or less (especially between 250 and 600 ° C) causes incomplete steam and chloride. Dioxins are easily generated by combustion.

In the present invention, incineration of biological wastes such as garbage and sewage sludge and dioxins, greenhouse gases, and emission of harmful substances into the atmosphere are avoided, and instead of landfilling, composting, or incineration, Energy and nutrient elements, such as nitrogen and minerals, are stored to about 100%, carbon is released slowly and fertilized, nutrient elements are made available or mineralized and circulated through the soil to cultivate fertile soil, Provide a way to increase soil organic carbon storage.

Technology for storing energy and nutrient elements (carbon, nitrogen, minerals, etc.) in the biological waste (biomass) of the present invention and circulating it to the soil (referred to as `` carbon / nitrogen storage technology '' or `` material circulation technology '') , Based on the `` low oxygen hot air closed circulation system '' and `` Shiodome (smoke distillation) -condensation-dry distillation '' process combined with a drying kiln, condenser (or condensing tank), hot air furnace, etc. Food processing, agriculture, forestry, and fishery waste, livestock poultry manure or sewage sludge, etc.) are subjected to destillation drying, sterilization and deodorization, solid-liquid separation, and then the evaporated liquid is condensed and recovered. Classified as `` artificial '' etc. (of which energy and nutrient elements such as carbon, nitrogen, mineral etc. are stored in the organism, and carbon is effective, nutrient elements are made available or mineralized) “Biological vinegar”, “Biological manure” or “Carbon nitrogen agent” By refining (composite fertilizer) etc. and storing 100% of the nutrient elements of biological waste and returning it to the soil as all-element fertilizer of the plant, it is possible to make use of its material cycle, nurture fertile soil, and increase soil organic carbon storage In addition, it is a “material recycling technology” in ecosystems that realizes zero emissions of dioxins, greenhouse gases, and harmful substances.

  The technical features of the present invention are realized by a combination of the following processes.

  (1) Drying kiln, condenser (condenser and cyclone separator or condenser tank, etc.), biological vinegar storage device, hot stove, solar power generation system, two-stage heat pump and heat pipe residual heat recovery system (hereinafter referred to as `` remaining heat recovery system '') "Low oxygen hot air closed circulation system" (hereinafter referred to as "closed system"). This “closed system” is used to process the waste “condensation-condensation-dry distillation”.

  (2) First, wet waste is sent to a hot-air drying kiln, and it is sterilized and deodorized at the same time that it is decomposed by distillation, solid-liquid separation, carbon, nitrogen and other elements. The hot air sucked into the hot air drying kiln is hot air prepared in the hot air furnace of the previous process.

  (3) The hot air temperature of the Shiodome drying process is 110-150 ° C (maximum 200 ° C or less). This temperature range does not cause sterilization, sterilization and deodorization at the same time as waste drying, evaporation of water and solid-liquid separation, and combustion reaction does not occur. Instead, energy such as carbon, nitrogen and minerals in the organism is used. Decompose nutrients-make them effective, make available or mineralize and store. Also, unlike the waste incineration, dioxin production can be suppressed thoroughly.

  (4) The “closed system” does not discharge exhaust gas and waste vapor to the atmosphere. A condensation / separation device such as a cyclone or a condenser is installed between the drying and combustion processes, the exhaust gas exiting the drying kiln is cooled, the condensed water vapor (evaporated liquid) in the exhaust gas is condensed, separated, and left standing and filtered. -Purify ecological "biological vinegar" as a natural resource through processes such as redistillation. This biological vinegar is excellent in antibacterial, deodorant and insecticide, and is an excellent “antibacterial deodorant” or “biological liquid fertilizer”.

  (5) Construct a two-stage heat pump and heat pipe residual heat recovery system, reduce the temperature of the condenser cooling water used for condensation recovery of the organism's evaporating liquid, circulate and use the cooling water from the exhaust gas The amount of heat generated is released at the low temperature side of the residual heat recovery system and is transferred to the circulating gas in the passing flow to the high temperature side as a heat pipe. The temperature of the circulating gas reaches 150 ° C or higher and is sent to the drying kiln again. Recycle the garbage repeatedly.

  (6) The “Toshiba”, “Iron / Aluminum Magnetic Sorter”, “Pulverizer” and “High Density Combined Sorter” are used to automatically control the dried product from the drying kiln in a sterile, odorless and anhydrous environment. `` Reusables '' (metal, plastic, etc.), `` organisms '' (natural products such as moss, garbage, pruned branches, grass, fallen leaves, paper waste or agriculture, forestry, and fishery waste), It is classified into four types: “artificials” (containers and packaging such as plastic waste, rubber, cloth waste, and industrial products) and “incombustibles” (inorganic). Among them, the “organisms” are dry matter of the living organisms in which energy and nutrient elements such as carbon, nitrogen, minerals, etc. are stored. Purify "biological manure" or "carbon nitrogen agent" (soil all-elements-biological compound fertilizer). The “artificial” (container and packaging waste) is a dry combustible material that is put into the high-temperature hot-air stove in the solar power generation system of this system, burned at high temperature and low oxygen (dry distillation), and the circulating gas is heated to a high temperature. The hot hot air generated from the hot stove is mixed with the circulating gas bypassing the hot stove at the exit of the hot stove to adjust the temperature, and then sucked into the drying kiln again to continue drying the wet waste. As described above, solar energy is used to dry and dry wet waste, and artificial waste is burned, and the circulating gas repeatedly performs heat and mass transfer in the “closed system”.

  (7) The dehydrated circulating gas passing through the condenser is further dehydrated by an after cyclone separator, and the “biological vinegar” is separated and recovered again. The dehydrated circulating gas at the outlet of the cyclone separator is returned to the electric hot blast furnace by the pipeline, and heat / mass transfer is repeated as hot air or circulating gas as described in (6).

  (8) The combustion property of the hot air furnace for generating the high temperature hot air of the present invention is high temperature low oxygen combustion. A solar power generation system will be installed and power will be supplied to the “hot air heater” of the “electrically-heated combustible high-temperature hot stove”. A certain amount of air and circulating gas are heated to 900 ° C or higher and injected into a hot stove to maintain high-temperature, low-oxygen combustion properties. At the same time, dry artificial combustible waste is sent into a high-temperature air stream for dry distillation. The generated hot air and the circulating gas in the pipe line are mixed and temperature-controlled, and then sent to the drying kiln again to repeatedly damp and dry wet waste. Both solar energy and the combustion of man-made dry waste become heat sources, saving fossil fuels.

  The biological waste treatment technology of the present invention is referred to as “carbon / nitrogen storage technology” or “material circulation technology”, and is also referred to as “shiodome-condensation method”.

  As mentioned above, the problems that exist in conventional waste incineration are the “short-circuit” volatilization loss of carbon and nitrogen, dioxins, greenhouse gases, harmful exhaust gases, etc. by incineration of biological waste and wet incineration. However, the present invention has solved all of these problems. In the “carbon / nitrogen storage technology” of the present invention, instead of fermenting and incinerating biological (biomass) waste, the “sealed system” was used to carry out treatment processes such as “stain-condensation-dry distillation” and so on. By classifying the dry matter of garbage into `` organisms '' and `` artifacts '', carbon, nitrogen, minerals, etc. are separated and stored, and carbon becomes slow and effective carbon (pool), nitrogen And minerals, etc., can be directly absorbed by plants when all elements are stored, made available, or mineralized by drying the smoke at 100 ° C or higher. Therefore, ultimately, ecosystem materials such as “biological vinegar”, “biological manure” or “carbon nitrogen agent” are obtained. Biological waste “carbon / nitrogen storage technology” can reduce the generation of dioxins, and does not generate carbon / nitrogen oxides or methane gas, and does not emit greenhouse gases (CO2, CH4, N2O, etc.) and hazardous substances. Realized. Therefore, the present invention allows the recycling of the nutrient elements of biological waste to the soil in the form of effective carbon, available or inorganic nitrogen, and minerals, thereby cultivating fertile soil. “Material recycling technology” in ecosystems that can increase organic carbon storage.

Moreover, the heat source system of a drying kiln consists of the following four. 1) Electrothermal dry combustible high-temperature hot-air oven (powered by a high-temperature air heater in the main furnace) powered by a photovoltaic power generation system that uses dry “artificial” (non-living) combustible waste as fuel. 2) A hot stove powered by dry combustible waste and coal (or heavy oil, gas, etc.). 3) An electric hot stove powered by a solar power generation system. 4) Inside the drying kiln is a high-temperature exhaust gas from other industrial production processes and a dry combustible material hot air oven of this system.

It is a systematic diagram of the waste disposal process in "Material circulation technology". FIG. 5 is a technical system diagram shown in FIG. 1 and is one of the system diagrams of the waste treatment technology in the “material circulation technology” of the present invention (although the technical system diagrams of FIGS. 2 to 4 are omitted here). FIG. 5 can be referred to).

  There are four specific implementation methods in the present invention, as described in the “instructions” (process (2)), the drawings, and FIGS. In these four systems, there are differences in the heat sources used to dry waste in a garbage drying kiln. Next, specific examples of FIGS. 1 and 5 will be introduced.

  FIG. 5 is a system diagram of the waste treatment process in the “material circulation technology” of the present invention. The fuel used in this treatment process is dry combustible man-made waste, and power is supplied to a high-temperature hot-air furnace (high-temperature air-fired furnace) by a photovoltaic power generation system.

  As shown in FIG. 5, the following procedure is included in the waste treatment technology in the “material circulation technology” of the present invention. (1) Drying kiln 1, Evaporated liquid cooling / recovery device (cyclone separators 21, 23 and condenser 3), biological vinegar storage tanks 41, 42, hot stove 5, solar power generation system 6, two-stage residual heat recovery system Installed a “closed system” for the “Shiodome-Condensation-Drying” process that combines 10 etc. (2) Dust is put into the waste hopper 86 and sent to the drying kiln 1 by the dust feeder 87 at the bottom of the hopper, and it is dried by distillation, solid-liquid separation, carbon effect, nitrogen and mineral availability, or mineralization At the same time sterilize and deodorize. (3) The hot air temperature of the drying kiln 1 is 110 to 150 ° C. (4) The water vapor (evaporated liquid) in the exhaust gas evaporated in the drying kiln is centrifuged, condensed, separated and recovered by the cyclone separator 21 and the water-cooled condenser 3, and the traps 25 and 34 and the filters 26 and 35 are separated. And stored in the bio-vinegar storage tanks 41 and 42. (5) The amount of heat taken by the cooling water of the condenser 3 is recovered by the residual heat recovery system 10, and the amount of heat released from the high temperature side of the heat pipe is transferred to the gas in the circulating gas return pipe 103, heated, and heated hot air pipe 104 gas becomes a part of the circulating gas in the drying kiln, mixed with the hot hot air pipe 15 in the circulation circuit 1 at the outlet of the high temperature hot stove 5 and sent to the drying kiln 1 to dry the debris in the drying kiln. Do. (6) The exhaust gas after dehydration passes through the condenser 3 enters the cyclone separator 23 and is further dehydrated, and further collects the biological vinegar liquid with a device such as a trap 27 and a filter 28, and goes to the storage tank 42. The circulating gas already dehydrated at the outlet of the cyclone separator 23 passes through the pipeline, partly returns to the high-temperature hot stove 5 (circulating gas circuit 1), and the other part returns to the residual heat recovery system 10 (circulating gas circuit 2). After being heated separately, the temperature is adjusted by mixing with the circulating gas in the bypass pipe 18 and sent again to the drying kiln for the next heat and mass transfer. (7) Garbage after drying in Shiodome goes out from the dry waste outlet of the drying kiln 1, and then automatically “wind sorter” 111, “magnetic sorter” 112, “pulverizer” 113 under sterile and odorless conditions And “High-Density Combined Sorter” 114, recycle 115 and 116, packaging (artificial) 117, biological (natural) 118, and non-toxic and odorless resource materials such as inorganic 119 and add treatments respectively. Use. Among them, the organism (natural product) 118 is a tethered organism in which carbon and nitrogen are separated and stored, and purifies “biological manure” or “carbon nitrogen agent”. Artificial combustible dry waste 117 is carbonized in the electrothermal dry combustible high-temperature hot stove 5 of this system, the circulating gas is heated, and the high-temperature hot air (circulation gas circuit 1) generated at the outlet of the high-temperature hot stove 5 and the residual heat recovery system 10 are used. After mixing with the heated hot air (circulation gas circuit 2), it is again sucked into the drying kiln 1 and repeatedly performs the detained drying-heat / mass transfer of the waste. In this way, the circulating gas is continuously circulated through the two circuits. (8) Install the solar power generation system 6 and supply electricity to the high-temperature air heater 51 in the electrothermal combustible dry waste high-temperature hot stove 5 to preheat a certain amount of air and circulating gas to 900 ° C or higher to the hot stove Inject and maintain hot air combustion. The circulating gas in the circulation circuit 1 is heated and sent to the drying kiln 1 to dry the wet waste. The operation of the bypass pipe 18 adjusts the hot air temperature of the drying kiln according to the ratio of the circulating gas in the bypass. By carrying out the above processes, energy and nutrient elements such as carbon, nitrogen and minerals in biological waste are decomposed, and the form of effective carbon (pool) and available or inorganic nitrogen and mineral, etc., respectively. In this case, “biological vinegar” and “biological manure” or “carbon nitrogen agent” are purified.

  The above is one specific embodiment of the present invention. Next, the features of the main equipment are introduced.

  (1) Drying kiln: The feature of the drying kiln 1 of this system is the horizontal cylinder rotary type, direct fire type hot air drying kiln (or the cylinder does not rotate, and a mixer type stirrer is installed inside the cylinder to make it wet. Stir the garbage). The direct fire type is a direct combustion type, that is, hot air generated in a hot stove is used in direct contact with a material. The diameter and length of the drying kiln cylinder are determined based on the amount of waste. The drying kiln is provided with a wet waste inlet 11, a dry matter outlet 12, a hot air inlet 13 and an exhaust gas outlet 14. The lower part of the rotary drying kiln is provided with a roller and a drive system, and the rotation speed is 1 revolution / min or less. Antiseptic coating is applied to the inner wall of the garbage drying kiln cylinder. A certain number of radial lifter plates are installed on the inner wall, and the dust in the drum is lifted by the lifter or falls freely to prevent material dispersion and hot air drift. Stir well to increase the efficiency of the tidal drying. The drum outer wall is kept warm with a heat insulating material. Hot air and waste can flow in the same direction (forward flow) or in the opposite direction (reverse flow). Automatic sensing of pressure, temperature, humidity, etc., fire and explosion proof devices and monitor monitoring system will also be installed. The gas temperature in the kiln is 110 to 150 ° C.

  (2) Cyclone Separator: Cyclone separators 21 and 23 are open-cylinder, low pressure loss, high collection efficiency cyclones (previous invention) and have functions of dust removal and liquid removal. The dust and drainage of the cyclone separator are automatically controlled. The drainage passes through the traps 25 and 27 and the filters 26 and 28 separately, and then enters the bio-vinegar storage tanks 41 and 42.

  (3) Condenser (or condensing tank): The condenser 3 is connected between the cyclone separators 21 and 23 in the exhaust gas circulation circuit. The feature is a condenser with a fin made of stainless steel. Circulating gas passes outside and cooling water passes inside the pipe. In the cooler function, the cooling water circulating in the pipeline maintains the fin surface temperature in the condenser at a low temperature, and the water vapor of the exhaust gas flowing outside contacts with the fin surface cooled to the dew point temperature to condense. In this way, the water vapor in the circulating gas is condensed to form water. Finally, it is collected in a biological vinegar storage tank 42 through a trap 34, a filter 35 and the like. The biological vinegar liquid in the storage tank is purified through a process such as standing, filtration, and re-distillation. According to the result of the chemical test, the biological vinegar is a multi-functional organic resource liquid mainly composed of organic acids, alcohols, ketones and phenols, which becomes a deodorant or biological liquid fertilizer.

  (4) Hot air generating furnace (hot air furnace): A hot air furnace is a device for supplying a heat source necessary for drying garbage. The heat source device of the present invention has the following four features. 1). An electrothermal combustible dry waste combined hot air furnace using combustible dry waste as a fuel and powered by a photovoltaic power generation system. An electric heating gas preheating device (Figures 1 and 5) is installed in the furnace. 2) Combined hot stove with combustible dry waste and coal, heavy oil, gas, etc. as fuel (Fig. 2). 3) Electric furnace with power supply from solar power generation system (Fig. 3). 4) Other exhaust gas at a temperature of 150 ° C or higher in the factory production process (exhaust gas from cement kiln process, exhaust gas from power plant turbine, exhaust gas from various boilers, furnace kilns, etc.) is added to the dry waste hot stove ( (Fig. 4). The technical feature of each hot stove in the present invention is that an electric heating gas preheating device is installed in the furnace to maintain high temperature and low oxygen combustion. Burning dry waste after drying in a drying kiln without incinerating wet waste (dry distillation). Also, in the “closed system”, the blower 52 sucks malodorous air from the garbage pit and maintains negative pressure. At the same time, the odor is sent into the hot stove and burns, and the amount of blown air only maintains the flameless combustion characteristics of the fuel. Limited. Most of the amount of air entering the hot stove becomes circulating gas, and after heating, it enters the drying kiln again, damps and dries the waste and continues to circulate. This system does not discharge any gas into the atmosphere.

  (5) Photovoltaic power generation system and residual heat recovery system: The solar power generation system 6, the two-stage heat pump, and the heat pipe heat recovery system 10 are features of new energy utilization and energy saving in the waste nutrient element storage technology of the present invention. The former supplies power to the high-temperature air heater 51 and all processes in the fuel furnace 5, and the installation of this apparatus helps high-temperature low-oxygen combustion in the combined hot-air furnace. The latter guarantees the circulation and use of the cooling water on the pipeline side of the condenser 3, and the amount of heat taken from the condenser cooling water return pipe 33 that passes through the low temperature side of the residual heat recovery system is the high temperature of the system by the heat pipe. Tell the side to the circulating gas in the flow. The temperature of the circulating gas is heated to 150 ° C or higher and sent again to the drying kiln, where the wet waste is repeatedly dried. It is not necessary to use mineral fuels such as coal and heavy oil in the whole process of solid-liquid separation and nutrient element storage according to the present invention by applying solar power generation and residual heat recovery system.

  In the present invention, there is no problem in industrial use. Both construction costs and operational costs are significantly lower than incineration, and biological waste is zero waste and 100% resources can be recycled into the global ecosystem. Carbon and nitrogen vaporize when landfilling, composting and incineration (CO2, CH4, N2O, etc. are discharged into the atmosphere) instead of `` biological vinegar '' and `` biological manure '' or `` carbon nitrogen agent '' As a “replenishment of carbon, nitrogen, minerals, etc.” to the earth, strengthening the circulation of carbon, nitrogen, minerals to the soil, increasing soil organic carbon storage and nutrient elements, creating fertile soil and green agriculture Promote the balance between development and ecosystem. It will help develop and produce future bioenergy crops, prevent global warming and promote sustainable development of society.

  By utilizing the biological resources of the present invention, the future of biofuels called the “Bio-Energy Circulation Law”, which has a deeper meaning due to “carbon filling, nitrogen filling, etc.” in the soil, is not far away. The “bioenergy circulation law” inferred based on the present invention is as follows.

  ``-Using the `` carbon / nitrogen storage technology '' of the present invention to produce carbon / nitrogen agents (soil all elemental agents) from biological waste and return organic carbon and nitrogen in the organism to the ground-Soil organic carbon storage volume -Increase fertile soil (including mountains and deserts)-Develop and plant bioenergy crops on a large scale-Produce biofuels on a large scale-On the other hand, with biological waste (including bioenergy crops) Create a carbon-nitrogen agent to return organic carbon and nitrogen in living organisms to the ground. This is the energy regeneration law of the future bioenergy era.

  The balance between the material cycle and the ecosystem in the ecosystem is also “sustainable” and “variable”. The “Bio-Energy Circulation Law” will make biofuels a perfect alternative to fossil fuels and prevent global warming. Problems such as resources, environment and sustainable development can be solved. The three pillars of “sustainable development” (economic efficiency, ecological balance, social responsibility) can be connected by the “carbon / nitrogen storage technology” (material recycling technology) beam.
