Description

Treatment of Organic Waste and High Concentration Wastewater by Energy Recycling System. {.}

The present invention relates to an organic waste and a high concentration of waste and wastewater treatment device, and more specifically, a facility for treating organic waste such as food waste, kitchen waste, agricultural livestock waste, foundry sludge, food processing waste, etc. and recycling them into feed and sweet feed. The present invention relates to a fermentation drying and distillation treatment method which is an important part of a waste treatment system such as a facility for treating high concentration sewage and wastewater below the effluent water quality standards such as over leachate, dehydration liquid, livestock waste, and industrial wastewater.

Today, 44,498 (ton / day) of household waste occurs nationwide, of which 12,949 (ton / day) of food waste occurs, accounting for 29.1% of the total amount of food waste, which accounts for only 9.6% of 1,239 tons of waste and 90.4% of landfills. Or it is incinerated and it causes leachate from landfills, water pollution from nearby landfills and groundwater pollution along with wastes from agricultural and fisheries distribution processes. Especially, it is urgent to prepare countermeasures due to complaints from residents around landfills.

When organic waste is landfilled, it contaminates groundwater and soil, and it is difficult to secure landfill. The treatment method by incineration reduces the combustion efficiency under difficult combustion conditions and suffers a lot of difficulties due to the emission problem of dioxins.

Therefore, the treatment of mixed organic wastes in general waste and recycling them into useful resources such as feed and compost has been spotlighted as a waste disposal measure that is not only a new concept of recycling but also a comprehensive environmental management system.

However, organic wastes are not only decaying quickly due to the complex collection process and water content, but also because their composition is not constant and only varies according to the characteristics of the region and the occurrence factor. In order to make a feed, a large amount of high quality excipients must be added, and when composting, moisture control agents such as sawdust and a long-term treatment period are required. Therefore, a high cost of treatment is required and economic efficiency is notably reduced. Since it is virtually impossible to meet the demands of the demand source, the livestock and crop farmers, which are real consumers, avoid the use and avoid the use. Therefore, they have been struggling with the disposal of organic waste processing by-product feed and compost, which is expensive. It is a reality.

In particular, since the removal of water is essential in the process of treating organic waste, it is important to efficiently supply the heat energy corresponding to the latent heat of evaporation of water and to recover and recycle the enormous amount of heat energy as much as possible.

However, in the case of the air circulation treatment system, which takes up most of the conventional treatment methods, high temperature and humidity are used in summer and low temperature in winter, and the temperature and humidity of the outside air are severely changed. In order to deodorize and exhaust the exhausted air, it is difficult to deodorize the air. Therefore, most organic waste treatment devices have to reduce the ventilation amount to a minimum. Due to the high humidity in the summer, the processing time is delayed. The performance of the equipment was inevitably affected by the conditions of the outside air.

In the case of hermetic high temperature steam drying system, which is mainly used in large-capacity facilities, dry drying is possible, but due to the characteristics of the high temperature treatment method, a large amount of energy is consumed, and once the input thermal energy is almost never recovered, it is discharged through the cooling tower. Since it consumes energy, it requires more expensive treatment costs than any other treatment methods.Because it uses banca-C oil as the fuel of steam boiler or waste heat of incinerator, it has many advantages due to environmental and limited conditions. It is causing problems.

In addition, the odor that is constantly generated in the large-area large-capacity processing facility cannot be processed even if any deodorization facility is installed. Therefore, in the past, it was virtually impossible to install feed facilities using food waste in municipal pipes in urban areas. Due to the distrust of the quality of the feed produced, the economic feasibility is very low.

Therefore, food waste treatment facilities in urban areas should not be hateful facilities but technically stable facilities that can contribute to regional development, and recycle the food wastes, which were environmental pollutants, with the best quality single tailings to maximize the waste disposal policy. There is a need for a facility that can faithfully perform and provide trust to the consumer with stability and convenience of operation of the facility.

As a result, there has been a growing interest in not only the treatment of organic waste, which is the main cause of environmental pollution, but also the way in which such waste can be treated and recycled. As part of this effort, organic waste can be disposed of and recycled into animal feed or organic compost. The equipment and equipment have been developed and developed steadily, and other organic waste treatment equipment is a method for removing moisture from materials in the treatment tank, and supplies a large amount of latent heat of evaporation by direct and indirect according to the characteristics of equipment and equipment. Adsorption, ozone oxidation, biological treatment using bio media, air cooling treatment, water cooling condensation system using cooling tower, cooling using refrigeration CYCLE, which are commonly used for deodorization and exhaust gas treatment after vaporization Formula treatment method, catalytic oxidation "Organic waste treatment method using heat pump and recycle air conditioning system" was developed as a treatment method that solved many problems of the various methods such as the multi-winding RECYCLE air conditioning system using the reprocessing method and the gas compression refrigeration system. Patent No. 10-1999-0019116 was filed on May 26, 1999, and on June 7, 1999, the application of the above patented technology, "Organic waste treatment system using a high-performance unit planting facility," was applied. -1999-0021053 The invention patent has been filed and the food waste of 5 tons per day produced by the above technology at the Earth Environmental Science Museum of Hannam International Environment Expo, which was conducted from September 21 to November 8, 1999 A feed system has been installed, which has been put into practical use by directly operating daily food waste provided by Hanam City's cleaning department.

This treatment method is more effective than other conventional treatment methods, and it circulates most of the air except for a small amount of ventilation in a recycle structure, so it does not discharge odors. While maintaining the environment inside the tank, it shows excellent performance such as recovering and recycling the input thermal energy as much as possible, and it is required to upgrade the performance and steady R & D according to the model development.

"Applicable organic waste treatment method using heat pump and recycle air conditioning system" filed by the applicant and filed with the patent application No. 10-1999-19116 as of May 26, 1999, "Organic waste treatment system using high-performance unit-type planting facility" filed an invention patent with the application number 10-1999-21053 on July 7 is a large unit and plant with a capacity of 5 tons or more and 200 tons per day. It is an excellent facility for the treatment of organic wastes such as food wastes in dry facilities, and the enormous thermal energy required for the latent heat of evaporation of moisture is recovered and recycled as the thermal energy input for the reheating of the air recycled from the heat pump air conditioning system. The amount of energy is about 25% due to the nature of the air, and the rest is used as hot water or through the condensing unit. This system is surely economical compared to other conventional treatment systems that emit almost all of the input thermal energy. However, large-capacity recycling facilities require enormous costs for operating costs for the energy input required by the latent heat of evaporation of water. Preheat the material put into operation at a certain temperature and supply basic heat energy to evaporate moisture, and then process the odor and gas included in the phase change material in the steam to be discharged at low temperature in the catalytic reactor unit. Oxidatively decomposes completely, and the heat of oxidation reaction generated at this time is composed of an energy recycling reactor system that can be recovered and recycled with the heat energy discharged in the vapor state as much as possible. To provide for.

Another object of the present invention is to generate no leachate or waste water in the process of treating organic waste with a very high moisture content, and in the case of other conventional organic waste treatment facilities, heating facilities and hot water supply facilities are virtually impossible to reduce the outside air temperature in winter. Due to the enormous heat dissipation loss and the working environment of workers in the treatment facility, it was inevitably poor, but in the present invention, a high temperature of about 80 to 90 ° C. naturally generated as heat energy is recovered from the energy cycle system after being completely processed in the reacta system. Since condensed water can be utilized as water that can be used sufficiently in a treatment facility without being discharged as it is, in the related art, a separate facility and energy source for hot water supply were required, but in the present invention, hot water naturally generated in a system Enough supply In addition, because it is configured to heat the treatment facility in winter, it is excellent in high efficiency that can recover 100% of the heat energy input for the initial preheating to treat the organic wastes and the heat of oxidation reaction in the Reacta system. To provide an organic waste treatment device that can exhibit performance.

It is another object of the present invention to utilize energy recycling and Reacta system as an environmentally friendly treatment method, which does not generate secondary pollutants, but also requires a low cost of treatment and operation costs compared to excellent water removal ability and recycling of condensate. It treats high concentrations of wastewater and livestock wastewater, and treats seawater as needed to provide fresh water treatment and distillation system that can get salt as a by-product.

Therefore, in order to achieve the above object, the present invention maintains an optimal environment for fermentation microorganisms to be activated and proliferate, and the materials are transferred to the inside of the treatment tank before, after, left and right in order to dry them at high speed. A ribbon type stirring facility (09) is installed, and it consists of a treatment tank (05) of a double-jacketed structure that maximizes the heat transfer area to the maximum to maximize the evaporative heat of moisture.

As shown in more detail in FIG. 3, the energy recycling reactor system 06 is installed at the upper portion of the BODY 05 at an upper shape, and the outer body is formed by the outer case 15. As a two-layer structure, one end of the lower layer is a suction chamber 16, and the bottom of the suction chamber has a structure in which water vapor generated from the treatment tank flows smoothly. An air filter 17 and a pneumatic air cleaner 18 are provided at the lower end of the suction chamber. On the outside of the side, an air supply unit 19 and an inspection port are installed, and the superheated steam amplifier 20 has a heat pipe heat exchanger 21 having a plurality of stages so as to receive the waste heat of the react outlet step by step. Passion is also arranged and the electric heating heater 22 is installed at the rear of the superheated steam amplifier. In addition, the catalytic reactor unit 25 installed at the upper inlet after passing through the intermediate chamber 23 having a structure connecting the upper and lower layers is composed of a platinum-based or palladium-based catalyst and is connected to an outlet of the catalytic reactor. 26, the heat pipe heat exchanger 21 connected to the superheated steam amplifier in an up-and-down integral structure is arranged in the same structure as the superheated steam amplifier, and the rear end thereof is composed of the superheated steam outlet chamber 27.

4 is a view showing a condensate storage tank 04, which is a general form of a hot water storage tank in which FRP material is insulated, and a heat exchange coil 28 made of a SUS corrugated pipe is built in the water tank. It is composed of a structure that can easily connect the pipe to connect the preheated air supply to the air supply port 19 of Reacta system through IN, OUT LET (29, 30) at the top of the tank. 31, the OVER FLOW connection port 32 has a structure in which a steam boiler feed pump 33, a hot water supply pump and a heating circulation pump connection 34 are easily connected to the pipe at the lower end thereof.

It is a system that can be applied regardless.

5 is a step-by-step treatment state and operation state of the saturated steam generated in the organic waste treatment apparatus according to an embodiment of the present invention. When the organic waste treatment apparatus is normally operated and a predetermined time elapses, 34) The temperature inside the material and the temperature of the material rises, and at this time, the gas is generated together with the water vapor, and the saturated water vapor 35 including the gas and the odor is connected to the exhaust port of the treatment tank. 16) It is introduced through the air filter (17) installed at the lower end. At this time, a certain amount of air is introduced and mixed from the air supply port (19) installed outside the side of the suction chamber, and oxygen required for oxidation of the phase change material in the catalytic reactor unit. Become a source of.

In the suction chamber, saturated steam is distributed evenly through the superheated steam amplifier 20, and is gradually heated to about 300 ° C while the heating energy is connected to the waste heat recoverer 26 of the Riacta outlet up and down integrally with the heat pipe. After receiving heat energy 36 recycled through the heat exchanger and lacking the heat energy recycled from the initial waste heat recovery machine, it passes through the electric heating heater 22 installed at the outlet of the superheated steam amplifier and gradually heats up to about 290 ° C. The catalytic reactor unit 25 is supplied.

Catalytic reactors are composed of platinum- or palladium-based honeycomb catalysts, and phase-change substances such as gases and odors contained in superheated steam heated to about 280 ° C to 300 ° C are completely oxidized while passing through the catalytic reactor unit. Since the heat of oxidation reaction is generated by conversion to gas or water vapor, the superheated steam at the outlet of the catalytic reactor unit is heated to about 400 ° C to 420 ° C.

It is condensed and discharged as it is supplied to the energy recycling system.

Referring to the drawings shown in more detail with respect to each configuration of the present invention.

6 shows the heat pipe heat exchange coil. The principle of the heat pipe was discovered 50 years ago by a scientist in the United States. When the special fluid such as freon or ammonia is enclosed in the metal pipe, the thermal conductivity is greatly improved and the heat transfer speed is increased. At about 3M per second, the thermal conductivity was about 1,300 times that of copper, which is about 500 times that of platinum.

In 1964, NASA developed a very effective thermal conductor that transmits a lot of heat even at a very small temperature difference using this principle. In Korea, heating coils and waste heat recovery systems using heat pipes were developed one after another, Therefore, in the present invention, in order to achieve the principle purpose of the energy recycle system, the excellent heat transfer capability of the heat pipe is applied as a heat conductor for recycling the waste heat of the outlet side to the preheating energy of the inlet side based on the catalytic reactor unit. It was decided as follows.

In addition, since the heat pipe applied in the present invention is used at a relatively high temperature, the pressure of the encapsulated fluid becomes considerably high, thereby increasing the heat transfer area at the air side with a significantly low heat transfer coefficient in the SUS pipe 38 of Φ 19 standard for high pressure. Special AL FIN (39) with heat resistance and corrosion resistance of Φ 45 standard is attached and the middle part is made of heat resistant boxing with groove (40) and specially manufactured to be assembled into the hole of coil plate (41). The heat pipe 37 was assembled into four rows of Φ 46 HOLE 42 alternately spaced at intervals of 60 mm on the coil plate 41 made of the same width as the Riacta system, so as to form a heat pipe heat exchange coil.

The core of the present invention is to saturate the inlet side on the basis of the catalytic reactor unit to completely oxidatively decompose phase changeable substances such as water vapor, gas, and odor, which are continuously generated in the treatment tank of the high speed fermentation dryer. In order to heat the temperature of steam to about 280 ℃ ~ 300 ℃, which is the proper treatment temperature, a large amount of waste heat including superheated steam at the outlet side is recovered and recycled without the supply of external heat energy during normal operation, and the upper side of the catalytic reactor unit is recycled. Energy recycling reactor system that recovers preheated energy by heat of oxidation reaction such as Hwasung VOC material and amplifies it to about 180 ℃ ~ 200 ℃, and supplies the superheated steam discharged to the latent heat of evaporation through the jacket of fermentation and drying tank. Material of heat pipe heat exchange coil and catalytic reactor The actual capacity, and according to the need to give a special structure is joined to the processing purpose.

7 shows an electric heating heater 22. An electric heating heater in which a fin coil type heater 44 having an appropriate capacity is assembled in a FRAME 43 of the same standard as the superheated steam amplifier 20. The general form and the use temperature of about 280 ℃ ~ 300 ℃ about relatively high temperature, so use the heat-resistant material.

8 shows the assembly diagram of the catalytic riba UNIT 25. The principle of catalytic combustion is about 700 to 900 ° C. for complete combustion in a general linear method for decomposing phase change VOC materials. In the catalytic combustion method, decomposition starts from about 150 ℃ depending on the type of VOC, and is completely oxidized with low energy at a low temperature of about 300 ~ 350 ℃ and decomposed into CO2, N2, and water vapor. It is a combustion treatment method that can drastically reduce fuel as it improves the durability of equipment and recovers heat of combustion reaction, and the role of catalyst is not directly involved in decomposing phase change materials such as gas and odor, but VOC material. Its role is to promote its action so that their combustion and decomposition are possible even at low temperatures.

Generally, platinum-based or palladium-based catalysts are widely used as catalysts, and the catalyst material is coated on a support having a large surface area, and the support material is gamma-type alumina having a large specific surface area such as honeycomb type, pellet type, and network structure type. In the present invention, the honeycomb-shaped rectangular honeycomb catalyst 45 of the honeycomb-shaped rectangular honeycomb catalyst 45 assembled in the FLAME 46 is UNIT.

As shown in detail in FIG. 9, the energy recycling reactor system of the present invention has a two-layer structure, and a separate partition separating the upper and lower layers is not provided, but the lower layer is the intake part and the upper part is the discharge part. The heat pipe heat exchanger coil of FIG. 6 is attached to the chamber units 16 and 27 where the lower layer is separated into separate zones in sequence, and the electric heating of FIG. 9 is applied to the lower layer of the end of the heat exchange coil. The heater 22 is assembled at the end of the upper layer part by assembling the catalytic reactor unit 25 of FIG. 10 and finally, assembling the intermediate chamber 25 having a structure connecting the upper and lower layers to the outer wall surface 15 ) Is finished with insulation and outer case, and check hole is installed at the side of chamber.

In the pilot unit, saturated steam introduced through the intake chamber 16 connected to the organic waste treatment tank 34 and the energy recycling reactor system 06 is approximately 90, which is the saturation temperature when the organic waste treatment apparatus operates normally. It was based on -93 degreeC.

When the preheating of the treatment system is completed, the maximum generation amount of saturated steam in the treatment system based on the organic waste 10 ton / 20hr capacity during normal operation is about 1,000 ㎥ / hr, and the air supply for supplying oxygen to the catalytic reactor is about 200 ㎥ / hr. The cross-sectional area of the heat exchange COIL passage was about 0.5 M / S.

In addition, the heat transfer capacity of heat pump heat exchange coil ΔT is based on the fact that saturated water vapor has a heating capacity of about 5 ° C when passing through the first row of heat exchange coils, and heat exchanger coil 10SET manufactured in 4 rows 1SET is obtained to obtain ΔT of 200 ° C. Since it is assembled in order to make a total of 40 rows by attaching them in series with a direct heat structure, when the saturated water vapor having about 90 to 93 ° C. flowing into the suction chamber reaches the inlet of the catalytic reactor, it is configured to be heated to about 280 to 300 ° C.

If the organic waste is quantitatively injected into the treatment tank of the high-speed fermentation drying system and the device is operated, the temperature of the internal material is initially low. Therefore, the steam boiler 02 is operated by the temperature sensor to supply thermal energy to the treatment tank jacket 08. It raises the temperature of the material and after a while gas and odors begin to develop with traces of water vapor.

Therefore, the Energy Recycle Acta system is also introduced to the suction chamber 16 with only a small amount of water vapor at the first time of operation, and then passes through the passage of the superheated steam amplifier 20 as it is, at about 280 ° C. in the electric heating heater 22. When heated and the catalytic reactor 25 is notified, phase-change substances such as gas and odor are completely burned and decomposed, so that the heat is further heated to about 380 to 420 ° C. by the heat of oxidation, and passes through the waste heat recovery device 26. Sufficient heat energy is recovered to the superheated steam amplifier 20 through the energy recycling circulation system 36 of the heat pipe heat exchanger connected up and down integrally, and heats saturated steam introduced from the treatment tank to about 280 ° C to 300 ° C. As it is a heating source, the electric heating heater operates only at the initial start-up and the preheating is sufficient. If it is the temperature of the processing tank material suddenly rises at any moment is not increasing rapidly the amount of generation of water vapor is the stable operation without the need for additional supply of heating energy due to increase steadily geolcheo little by little over approximately 2 hours.

As the apparatus continues to operate and the temperature of the material in the treatment tank is increased to some extent and the amount of water vapor generated increases, the amount of phase-change material to be treated in the catalytic reactor unit 25 increases with the increase of the heat of oxidation reaction. The enormous thermal energy of the superheated steam 56 at the exit of the catalytic reactor unit is sufficiently recovered as the heating energy in the superheated steam amplifier 20 along the energy recycling circulation system 36, and the remaining thermal energy gradually increases to the maximum. At the time of load, it becomes the superheated steam of about 180 to 200 ° C, flows into the outlet chamber 27 of the Reacta system, and is composed of a twin structure by the multi-turbo fan 12 of the multi-stage compression structure. As it is supplied to the double jacket of the steam generator, it is supplied to the necessary heat energy source by the latent heat of evaporation of water in the treatment tank. .

In addition, the important fact is that the amount of phase changeable substances such as gas, odor, etc. must change from time to time because the composition of organic wastes is not constant, and the quantity and quality of substances put into the treatment tank of fermentation drying system are always different. When the temperature is significantly increased above this level, the temperature of the superheated steam discharged by the increase of the heat of oxidation reaction in the catalytic reactor increases further and the amount of ΔT recycled due to the large difference in temperature between the waste heat recovery and the superheated steam amplifier. As a result, the temperature of the catalytic reactor inlet increases, and thus, there is a fear that an abnormal overheating phenomenon occurs in which the temperature of the catalytic reactor outlet increases further.

At this time, even if the temperature of the outlet superheated steam according to the situation of the catalytic reactor increases to some extent, the temperature at the inlet side is kept within a predetermined temperature to prevent abnormal overheating and the heat energy recycled from the waste heat recovery 26 to the superheated steam amplifier 20. Even if (36) is increased, it is necessary to control so that the temperature of the catalytic reactor inlet superheated steam (57) does not rise. In the present invention, the purpose of the present invention is to achieve the object through proper control of the air supply. The maximum generation amount of saturated water vapor based on the treatment system of 10 tons / 20hr capacity is about 1,000 m 3 / hr, and the air supply for oxygen supply to the catalytic reactor is about 200 m 3 / hr, as shown in detail in FIG. 9. Two air outlets (19) were installed at the upper end of the outer wall side of the saturated steam intake chamber with an electric valve equipped with an electric valve having a capacity of about 100 m3 / hr. Three places 24 were installed at the lower side of the outer wall side of the intermediate chamber between the ecta 25 and the suction chamber side air inlet 19 was preheated to about 90 ° C. through the preheating coil 28 installed in the treated water storage tank 04. After that, it is configured to be heated and introduced to about 280 to 300 ° C with saturated steam again, and the intermediate chamber side air supply port 24 is configured to supply external air immediately.

Therefore, when the energy recycling reactor system is normally operated, only the suction chamber side air supply unit 19 is operated in the open state. If the temperature of the catalytic reactor inlet side is about 310 ° C, the temperature sensor 55 It is detected by the inlet chamber side air inlet 1 and the middle chamber side air inlet 24 is opened. At this time, about 100 ㎥ / hr of cold outside air flows, the temperature can be lowered by about 30 ° C. When the temperature reaches about ℃, the two air supply units are switched to supply only the outside air at the intermediate chamber. Therefore, if the temperature of the catalytic reactor inlet does not rise abnormally excessively, it can maintain a sufficient temperature. When the temperature reaches about 320 ℃, the air supply unit, which is installed as a safety valve on the middle chamber side, is operated so that an alarm sounds.

Therefore, when the material is put into the organic waste treatment system and started to operate, the initial preheating time may be slightly different due to the temperature difference of the material brought in according to the season, but after about 2-3 hours, the whole system is sufficiently preheated. The superheated steam at the outlet of the catalytic reactor is increased in accordance with the increase in the heat of oxidation reaction such as the gas, odor, etc., which are normally operated by the energy recycle reactor system and introduced together with the water vapor in the treatment tank and completely oxidatively decomposed in the catalytic reactor unit 25. The enormous thermal energy of) is sufficiently recovered as the heating energy in the superheated steam amplifier 20 along the energy recycling circulation system 36, and the remaining thermal energy is gradually increased while being in the superheated steam state, and is weak at maximum load. It becomes superheated steam at about 180 ℃ ~ 200 ℃ and flows into outlet chamber 27 of Reacta system. Since it is supplied to the double jacket of the processing tank 08 which consists of a twin structure by the multi-turbo fan 12 of a compression structure, it is supplied to the heat energy source required by the latent heat of evaporation of moisture in a processing tank.

At this time, since the superheated steam flowing into the double jacket 08 of the treatment tank from the outlet chamber 27 of the energy recycle reactor system includes air and CO2, which are non-condensable gases, in order to effectively discharge the condensate with a general blower, Since it is impossible and requires a very high discharge pressure, the multi-turbo FAN 12 is a high performance turbo blower with a multi-stage compression structure, which is specially designed and manufactured for application to the present invention having a relatively high use temperature, and has a maximum discharge pressure of about 4,200 mmAq. The suction force is about 4,000 mmAq. Therefore, the part connected to the suction side of the multi-turbo fan 12, such as the treatment tank 34 and the energy recycling system, is under negative pressure during normal operation, and the vacuum degree is 2,000 to 2500 mmAq (absolute pressure of about 0.75). It operates with low vacuum of ~ 0.8 kg / ㎠a) and the saturation temperature of water in the treatment tank is about 90 ~ 93 ℃, so Moisture evaporates rapidly at low temperatures and the process by-products are not carbonized, so the recyclability is very good and the heat transfer effect is improved due to the ΔT difference with the superheated steam supplied to the double jacket 08 of the treatment tank. It can also be effective.

If the organic waste is put into the treatment tank and the machine is operated, the steam boiler supplies the heat energy source supplied to the double jacket 08 of the treatment tank in the initial preheating stage. When the water supply pump installed in the condensate storage tank is supplied automatically, when the preheating of the processing system is completed and it operates normally, the condensate outlet 58 of the processing tank generates high temperature condensate of about 80 to 90 ° C. Saturated water vapor containing gas, odorous phase change materials such as odors and the like was mixed with an appropriate amount of air and completely oxidized and decomposed in an energy recycling system. It is supplied to the double jacket (08) of the treatment tank in superheated steam state and heat energy by latent heat of evaporation of water in the treatment tank. As it is taken away, it is condensed and discharged, so it is a kind of distilled water with almost no foreign matter.It can be used as hot water and hot water that can be used in processing facilities.It is used as heating energy because it is circulated in hot water radiators and FCU during the winter season. It can be used for all water except for cooling by outside air and using it directly as drinking water. Therefore, 100% of the heat energy and heat of oxidation reaction generated in the Reacta system can be recovered and recycled. It is possible to provide an organic waste disposal apparatus that can exhibit excellent performance with high efficiency.

Another object of the present invention is to completely treat the high concentration of wastewater, such as leachate, livestock wastewater at low cost by applying the energy recycling system of the present invention as shown in detail in FIG. After constructing pilot unit of wastewater distillation treatment system and flowing into saturated water vapor state from distillation treatment tank 61, phase change materials such as gas, odor, etc. are completely oxidized and decomposed into superheated steam state in the energy recycling system (06). The circulating system of the discharged water vapor has a maximum discharge pressure of about 4,200 mmAq and a maximum suction input of about 4,000 mmAq by the high-performance multi-turbo fan (12) of multi-stage compression structure. Accordingly, the part connected to the suction side of the multi-turbo fan. Is operating under low pressure with normal vacuum and 2,000 ~ 2,500mmAq (absolute pressure about 0.75 ~ 0.8kg / ㎠a) and low vacuum and the saturation temperature of water in the treatment tank is about 90 It is configured to be 93 ℃ and the pre-heating of the treatment system is completed, and the maximum generation amount of saturated water vapor in the system standard of wastewater 1 ton / hr treatment capacity is about 2,000 ㎥ / hr during normal operation, supplying oxygen to the catalytic reactor Is about 400 ㎥ / hr, and the cross section of the energy recycling system heat exchange COIL passage has a maximum wind velocity of about 0.5 M / S, and the heat transfer capacity ΔT of the heat pump heat exchange coil In order to obtain ΔT of 200 ℃ on the basis of having a heating capacity of about 5 ℃, the heat exchanger coil 10SET made of 4 rows 1SET is assembled in a series of direct heat structures in order to make a total of 40 rows. When the saturated steam reaches the inlet of the catalytic reactor, it was configured to be heated to about 280 ~ 300 ℃.

11, a distillation system 60, a waste water storage tank 62, a steam boiler 02, a condensate storage tank 04, a treated water storage tank, to which the energy recycle system of the present invention is applied, as shown in more detail. 63) If the system is designed to treat high concentration sewage such as leachate, livestock wastewater, etc. as basic equipment including pumps and pipes, it does not generate secondary pollutants such as sewage and leachate as an environmentally friendly treatment method. It is a groundbreaking wastewater treatment method that can handle enough water at low cost compared to the excellent water removal ability and the recyclability of naturally occurring condensate during the treatment process. It can be applied to distillation system that can provide excellent treatment system, but it can dry organic waste. Since the waste itself has a volume of solids, the water is dispersed, and the moisture contained in the waste is evaporated by evaporating it out, but the waste water is dried in various amounts of water or a small amount of solids. Because it is a liquid waste contained, it is necessary to maximize the heat transfer area and the surface area of the waste water as much as possible in order to evaporate moisture quickly.

Therefore, the energy recycle reactor distillation system of the present invention is about Φ 42 specially manufactured with heat-resistant synthetic rubber inside the treatment tank 61 in a manner to maximize the sufficient heat transfer area and the surface area of the waste water in the treatment tank. Filling the porous ball 64 up to the shaft 65 of the stirrer and continuing to turn it over with the ribbon type stirrer 09, supplying heat energy through the double jacket 08 of the treatment tank, so that the temperature of the inside of the treatment tank and the heat-resistant special hole is about 90 degrees. After heated to about ° C, the waste water temporarily stored in the storage tank 62 is evenly sprayed through the nozzle 67 at the upper end of the treatment tank 61 by 1 ton per hour by the transfer pump 66 installed at the bottom of the tank. When it is relatively small, the volume of water is diffused and mixed in a large area of high temperature so that it can be vaporized in an instant and flowed into the energy recycling system that is already preheated and operating. The basic system for the supply of thermal energy and the treatment of saturated steam generated is operated by the same principle as the organic waste fast fermentation and drying system using the energy recycle system. It is a breakthrough treatment method that can treat high concentration wastewater, such as livestock wastewater, in the clear water below the discharge water quality standard, and the treated condensate discharged at about 80 ~ 90 ℃ during normal operation is temporarily stored in the storage tank (04) of about 2㎥ It is used as the air supply preheating of the system and water supply of the steam boiler, and if a predetermined level or more is transferred to the large-capacity treatment water storage tank 63 by the pump 67, the heat exchange coil installed inside the waste water storage tank 62 in the transfer process. Preheat the wastewater and waste water which is temporarily stored while passing through (68) and cooled down to about 40 ~ 50 ℃ It is to be treated and to utilize the hot water supply and irrigation required in the processing facilities after a store to the number of mass storage processing tank (63) and recycling excess is discharged.

In addition, if the supply tank is depleted due to the depletion of waste, wastewater and dehydration liquid in the storage tank, the water content in the treatment tank gradually decreases, and when the water content of the sludge reaches about 25%, the equipment is automatically stopped by the water content sensor. Wastewater treatment sludge is used as raw material for compost, and food waste leachate treatment sludge is a high-temperature sterilized organic powder containing a large amount of salt, so it is expected to be used as a short additive for salt supply of animals in the future. The sludge should be entrusted to a landfill facility for disposal.

Therefore, according to the present invention, in order to process organic wastes and convert them into feed and sweet rice feed, the preheating is carried out in order to completely process saturated steam including gas, odor, and phase change substances generated in the treatment tank in the fermentation drying at high speed. The energy recycling system is basically configured to recycle the input thermal energy after recycling only the energy, and a high temperature environment of about 700 ~ 900 ℃ is required for complete combustion to decompose phase change VOC materials. However, depending on the type of VOC, the decomposition starts from about 150 ℃, and it is equipped with a catalytic ritata system that can be completely oxidized with only little energy at a low temperature of about 300 ~ 350 ℃ and decomposed into CO2, N2 and water vapor. To the heat of oxidation reaction generated from the unit Since the present invention has been developed by the present applicant and filed an invention patent with the application No. 10-1999-19116 as of May 26, 1999, "The method of treating organic waste using heat pump and recycle air conditioning system" and the patent technology The application of the invention patent on June 7, 1999, filed with the patent application No. 10-1999-21053, the "organic waste treatment system using a high-performance unit type planting facility" is a fatal problem despite its excellent performance. Most of them can be eliminated, so it can show excellent performance by constructing an "energy recycling system" that can build a low cost organic waste recycling system.

Another effect of the present invention is that when the organic waste recycling system operates normally, high temperature condensate water of about 80-90 ° C. is generated in the double jacket 08 of the treatment tank, which is treated as a kind of distilled water with almost no foreign matter. It can be used as hot water and hot water that can be used in the facility.In winter, it can be used as a heating energy because it is circulated to hot water radiators and FCU, and it can be used as any water except for cooling over the outside air and using it as drinking water directly. Therefore, it is possible to recover and recycle 100% of the heat energy and the heat of oxidation reaction generated from the Reacta system for the initial preheating to treat the organic wastes to be imported, thus providing an organic waste treatment apparatus that can exhibit excellent performance with high efficiency and thermodynamics. can do
