Description

  The present invention relates to a waste treatment method and a waste treatment system for converting waste into a valuable product that can be used as an alternative energy material.

There are social demands such as effective use of resources, CO ₂ reduction, environmental measures, etc., for example, in the case of garbage, compost type, extinguishing type, dry type, carbonization type, incineration type, etc. These processing methods and systems have been put into practical use.

  The compost-type garbage treatment method is a method that decomposes and ferments with special microorganisms to produce recycled organic fertilizer in about 15 hours, but only for garbage, and complete separation at the time of input is an essential condition. The salt damage in the garbage becomes a problem, and it is necessary to periodically input expensive microorganisms, so the running cost is high, and the processing takes time. There is.

In the extinguishable garbage treatment method, garbage is put into a culture processing machine, and the waste is decomposed into water and CO ₂ by a special microorganism to be eliminated by about 70%, and the residue that could not be eliminated can be made into compost. However, complete separation at the time of throwing in the waste is necessary, and when the metal is mixed, the processor is likely to break down. Also, 100% of garbage cannot be eliminated. Depending on the waste that has been thrown in, there is no choice but to incinerate the residue that could not be eliminated as a combustible material. In that case, the running cost increases because of the process of collection, transportation, and incineration. Since microorganisms are used in the same way as the compost type, there are restrictions on the microorganism's activity temperature and oxygen supply to the microorganisms, and the microorganisms are expensive and the running cost is high. Yes, if it is a continuous input type, it becomes a large facility.

  In the dry garbage disposal method, the waste is dried using a warm air heater or a microwave. The warm air heater type dry garbage treatment method is to reduce the amount of garbage to 1/7 or less by suppressing the proliferation of germs by evaporating the moisture of the waste with a warm air heater and drying it. The residue can be composted. However, in this case, it is necessary to bury the soil once and decompose with microorganisms, and the salt damage of compost becomes a problem. Therefore, depending on the garbage, there are cases where the dried residue can only be incinerated as a combustible material. In this treatment method, it takes time to dry the core of the waste treatment product, and the running cost increases. In addition, the exhaust temperature of the deodorizing device is high, and ventilation equipment to prevent the ambient temperature from rising is necessary. In addition, when incinerated as a combustible material, collection and transportation costs. Since this dry type garbage treatment requires time, it is unsuitable for continuous input, and if it is a continuous input type, it becomes a large facility.

  In the dry garbage disposal method using microwaves, garbage is heated by microwaves used in a microwave oven and dried to reduce the weight. Depending on the waste input, the dried residue can be turned into compost. As a problem, complete separation at the time of throwing in the waste is necessary, and it is likely to cause equipment failure when metal is mixed. Depending on the waste input, there is no choice but to incinerate the dried residue as a combustible material. A large amount of processing cannot be performed up to about 10 kg at a time, and continuous feeding cannot be performed. Others have the same problems as the hot air heater type garbage disposal method.

  In the carbonized garbage treatment method, garbage is heated to generate gas, and the gas is burned to carbonize the garbage, which is used as a fuel or a soil conditioner. As a problem, since the machine itself becomes high temperature, a dedicated ventilation facility and a processing chamber are required. Therefore, it is necessary to make the processing machine have a heat insulating structure, and since it is large and the apparatus main body is expensive, it also requires a running cost. Notification to the fire department is required, and fire equipment is also required. In addition, there is an obligation to report exhaust gas component analysis results, and analysis costs are also required. In addition, the cost of industrial waste treatment of the remaining ash is high.

  The incineration-type garbage disposal method burns garbage into ash and disposes it in landfills. As a problem, since the processing machine itself becomes high temperature, a dedicated ventilation facility and a processing chamber are required, and the processing machine becomes large in size and expensive due to the heat insulation structure, and the running cost is also increased. In addition, notification to the fire department is necessary, and fire equipment is also required. Analysis costs are also required due to the obligation to report the exhaust gas component analysis results to the competent authority. Furthermore, there is a possibility that dioxins may be generated during the burning process because of the cost of industrial waste treatment of the remaining ash. Incineration of garbage with a high salt content and moisture content provides a source of chlorine, a component of environmental hormones. Incineration of garbage with a large amount of salt and moisture causes uneven combustion temperature and shortens the life of the incinerator.

  The present invention was made in order to solve the problems of the above-described method for treating garbage including garbage and the system for treating garbage.

  FIG. 1 is an operation follow chart of the waste disposal method and waste disposal system of the present invention, and FIG. 2 is an example of a waste classification table. The basic concept of the present invention will be described with reference to these drawings.

  An important concept in the present invention is to find a solution on how to make a high-value-added processing product (valuable product) efficiently based on a preliminary survey of waste and its data. .

  In step S1 of the garbage pre-investigation, it is important for the user to grasp as much as possible what kind of garbage (weight, capacity) and what kind of contents and when. FIG. 2 shows an example of the garbage classification table. As is clear from the garbage classification table, garbage is classified into normal garbage and contaminated garbage. The waste disposal method and the waste disposal system of the present invention are characterized in that both can be treated.

  According to the waste treatment method and the waste treatment system of the present invention, for ordinary garbage, for example, if only coffee grounds or cracks are used, a raw material for activated carbon can be produced as a treatment product. In addition, contaminated waste such as contaminated waste plastic, contaminated waste vinyl, contaminated foamed polystyrene, contaminated paper waste, and cigarette butt has been conventionally only incinerated, and incineration has been costly. The processing system can turn this into a valuable material. For example, these contaminated wastes can be processed into processed products for coal substitute energy materials.

The amount of food waste varies depending on the type of store, time of day, day of the week, month, season, etc., but this preliminary survey must be continued for at least one week in order to grasp the data of changes over time. . And the optimal separation method from the viewpoint of improvement of the sanitary environment, the optimal separation method from the viewpoint of improvement of the recycling rate, the optimal separation method from the reduction of CO ₂ , the optimal separation method from the viewpoint of cost performance, and the optimum from the viewpoint of space efficiency Examine the sorting method and the optimum sorting method from the viewpoint of the crusher performance, and propose and inform the user of the most effective sorting method and set up the waste disposal machine.

  Next, based on the analysis result of the waste pre-investigation, an enzyme program to be used in the waste disposal machine is determined in step S2. In the waste treatment machine used in the present invention, the enzyme is used to stabilize the components and take out the treated product, instead of decomposing the waste using microorganisms or altering it by a chemical reaction. It plays a role in promoting and promoting stabilization. Here, the waste stabilization treatment refers to the homogenization of the waste, the decomposition by the enzyme, the disinfection and the drying, and may further include deodorization. Homogenization is achieved by making the composition uniform by mixing with stirring.

  One or a plurality of combinations of enzymes suitable for the analyzed waste components are selected from about 3000 types. Among them, for example, when the garbage is garbage, the plant-based enzyme of the food industry enzyme is mainly configured in consideration of recycling and utilization as an energy material. In particular, the papaya enzyme has the property of degrading proteins, carbohydrates, and fats, and the pineapple enzyme degrades proteins. After degradation, proteins become amino acids, carbohydrates become sugars, and fats become glycerin.

  In order to maximize the degradation of waste components by enzymes, the optimal enzyme enzyme dosage with the temperature conditions (optimum temperature of the enzyme), decomposition time, decomposition capacity according to the amount of waste input, and Along with the selection, a blending program for dropping an enzyme according to the amount of waste input from the crushing device and the processing tank at the inlet of the processing machine is important. Since enzymes are used for stabilization in this way, the temperature in the processing machine can be suppressed to several tens of degrees, unlike the decomposition of garbage by microorganisms. Heating with an electric heater becomes unnecessary, and energy consumption can be reduced accordingly.

  Disinfection of garbage may be performed in a processing machine at a high temperature of about 80 ° C. for about 10 minutes, for example, hot water or hot air disinfection. This sterilization treatment can kill or inactivate most vegetative bacteria, tuberculosis bacteria, fungi, and viruses except spores to below infectable levels.

  The garbage drying process is performed by evaporating excess moisture in the garbage and exhausting it with the waste heat of the fresh heater and deodorizing apparatus blown into the treatment tank.

  For deodorization of garbage, deodorization by an enzyme and deodorization by a deodorization apparatus can be applied. The former can suppress the growth of bacteria (such as Bacillus subtilis and spoilage bacteria) that generate malodors due to the degradation of the enzyme, and can suppress spoilage by adding yeasts, noodles, lactic acid bacteria, radiobacteria and the like. In the latter case, a platinum catalyst or a photocatalyst can be used. In the case of a platinum catalyst, the odor can be removed at a high temperature. Moreover, when applied together with the function of the former enzyme, deodorization can be performed more effectively, and the running cost can be reduced.

  Control parameters such as moisture control, temperature control, supply / exhaust control, etc. are executed in step 3 in order to activate the above-described enzyme containing deodorization in the waste treatment machine and stabilize the waste treatment. In this way, the optimum program for the waste disposal machine is determined. Next, the garbage disposal machine executes the program in step 4. At the same time, the data is fed back to the enzyme program S2 and the control program S3 corresponding to the waste component in step S2 in real time, and fine adjustment is repeated.

  Furthermore, the optimum program and the data on the operation of the waste disposal machine are also given information to the maintenance program in step S5, and the maintenance program is started up accordingly and used for the operation of the waste disposal machine.

  Next, a waste disposal machine used in the above-described waste disposal system will be described. FIG. 3 is a schematic diagram showing the configuration of the waste disposal machine 10.

  In the receiving device 4, the processing tank 5, and the scraping device 6 of the processing machine main body 3, a paddle for stirring and transfer is attached to a common rotating shaft 31, and a plate is provided at the tip of the paddle. The receiving device 4 stores the waste transferred from the crushing device 2 and sends it to the treatment tank 5 with stirring.

  The treatment tank 5 further stirs the sent waste and stabilizes the waste using an enzyme. There are about 3000 types of enzymes, and the optimum combination of enzymes is determined from the components of the waste and the requirements to be processed. The stabilized processing product is taken out from the processing machine main body 3 by the scraping device 6. This processed product can be used immediately as a carbide that can be used as an alternative energy source or further processed and used as a fertilizer or an intermediate material for alternative energy materials. That is, the processing product by the waste processing method and the waste processing system of the present invention is converted into a valuable material (valuable product).

  Next, the configuration and function of each unit will be described in detail. As shown in FIG. 4, the crushing apparatus 2 includes a funnel-shaped housing 21, a garbage input hatch 22 located at the top, a crusher 23 located at the middle, a draining device 24 located below, and a transfer device. 25 and an abatement device 26 provided at the lowermost stage.

  The input hatch 22 is partitioned by a lid so that the crusher does not start when the lid is open, and the negative pressure circuit prevents odors from leaking. The crusher 23 includes a motor driven primary rotor 23a and a secondary rotor 23b, and crushes metal waste such as contaminated paper and vinyl, spoons, forks, and the like. In the case of overload, the rotation of the primary and secondary rotors 23a and 23b can reverse the rotor and provide a cleaning function for preventing contamination of the crushing blade.

  The draining device 24 removes moisture from the waste having a high water content and reduces the water content. The transfer device 25 is configured to move the extrusion plate 25b to the compression plate 25c by the belt driving device 25a. The drained waste is pressed against the compression plate 25c by the extrusion plate 25b, and the compression plate 25c is moved upward or downward. By evacuating, the crushed garbage can be transferred to the receiving tank through the receiving port of the receiving device 4. The detoxification device 26 includes a coarse filter, a fine filter, and a sedimentation tank, and removes the dust in the water that has been squeezed from the crushed waste.

  FIG. 4 is a perspective view of the receiving device 4, and FIG. The receiving device 4 includes a receiving tank 41, a plurality of transfer paddles 43 and 44 attached to a shaft 31 that can be rotated in a clockwise direction and a counterclockwise direction, crushed garbage transfer plates 45 and 46 attached to their tips, and crushed garbage intake It is composed of a partition wall (not shown) on the side of the crushing device 2 provided with a mouth, a receiving tank partition wall 42 having an opening for transferring dust at the top, and nozzles 11 and 12. The transfer paddles 43 and 44 can be detached from the rotary shaft 31, and the transfer plate 45 is provided so as to be removable from the transfer paddles 43 and 44.

  The receiving tank 41 temporarily stores the transferred crushed waste, and can continuously input the waste even when the waste is being stirred in the treatment tank 5, and the crushed garbage is moved out of the processor main body 3. This is provided to prevent leakage.

  As shown in FIG. 4, the crushing waste stored in the receiving tank 41 is processed when the transfer paddle 44 rotates counterclockwise and the transfer plate 45 attached to the tip of the transfer pad 45 arrives at the opening above the receiving tank partition wall. 5 and cleaned by compressed air ejected from the nozzle 11. Similarly, when the transfer paddle 43 is rotated in the clockwise direction, the transfer plate 45 attached to the tip of the transfer paddle 43 is transferred to the treatment tank 5 when the transfer plate 45 arrives at the upper opening of the receiving tank partition wall, and is compressed air ejected from the nozzle 11. To be cleaned.

  Next, the details of the processing tank 5 will be described with reference to the perspective view of FIG. 6, the transverse sectional view of FIG. 7, and the longitudinal sectional view of FIG. The processing tank 5 is provided with a rotating shaft 31, stirring paddles 51, 52, and 53, a stirring plate 54 attached to their tips, and a stirring protrusion member 55. In the treatment tank 5, the dust transferred by the stirring paddles 51, 52, 53 and the stirring plates 54, 55 is stirred, and volume reduction and weight reduction processing is performed using an enzyme selected according to the components of the waste. After the treatment process is completed, it is sterilized and dried at a high temperature and stirred for further stabilization.

  To reduce odor by treatment using enzymes and stabilization by high temperature, increase the efficiency of treatment and stabilization by stirring, make the distribution of dust uniform and make it a good material as the first stage material of alternative fuel it can. The stirring paddles 51, 52 and 53 have a slight angle, and at the same time as stirring, the dust in the tank is moved to the left and right by rotating clockwise and vice versa to make the dust uniform. The stirring plate 54 at the tip of the paddle and the stirring protrusion member 55 provided on the side surface facilitate the mixing of air into the accumulated dust.

  The stirring paddles 51, 52, and 53 are removed from the rotating shaft 31 so that the stirring plate 54 and the stirring projection member 55 can be replaced. In addition, the stirring protrusion member 55 having another shape can be replaced according to the waste component of the treatment tank 5.

  For example, if there is a lot of vegetables / fruits with a lot of water, low-viscosity rice / noodles, and high-moisture content and low-viscosity, when the stirring projection member 55 scoops up the crushed waste, The shape (brush ladle-type stirring protrusion) in which a brush is attached to the contact surface of the receiving tank partition so as not to be scraped up. Alternatively, when the stirring projection member 55 stirs the crushed waste, a member (antenna type stirring projection) having a shape in which a plurality of branches such as an antenna are installed so that a large amount of air is mixed in order to evaporate a large amount of water. ).

  In the case of high-viscosity rice and noodles with low moisture content, high-viscosity rice and noodles, and high-viscosity waste, the stirring protrusion member 55 resists the high-viscosity dust when scraping the crushed waste. A member (skin merdle-type stirring protrusion) having a lower surface in a comb shape so as to correspond to the above. Or it is good also as a member (wing type | mold stirring protrusion) made into the shape of an airplane wing | blade so that it may respond to the resistance of a highly viscous waste, and may mix much air.

  When the water content and viscosity are low due to paper waste, contaminated waste plastic, and waste with a lot of contaminated vinyl, when the stirring protrusion 55 picks up the crushed waste, the contact surface of the receiving tank partition is lifted up to scrape all the waste. A member with a brush shape (blade ladle type stirring protrusion member) is used. Or it is good also as a simple-shaped member (stick-type stirring protrusion) only of the function which mixes a crushing waste and an enzyme equally, when the stirring protrusion member 55 stirs a crushing garbage.

  The scraping device 6 is located on the left side of FIG. 3 (that is, the waste disposal side) and scrapes out the product that has been treated and stabilized in the treatment tank 5. A discharge port 61 is provided, and a scraping paddle 62 attached to the rotary shaft 31 so as to be replaceable and a scraping plate 63 attached to the tip of the paddle 62 are scraped from the scraping port.

  Next, an embodiment of the operation in the waste processing method and the waste processing system of the present invention will be described with reference to FIG. The operation mode can be set according to changes depending on the type of business, type of business, type, time, day of the week, month, season, and the like. There are the following seven types of operation modes, which can be appropriately switched according to the state of the waste treatment.

  First, assuming a failure, start mode (START) that operates 100% of open air until the temperature of the deodorizing heater rises when the waste is in the treatment tank, and the amount of waste input per hour is small. A regular processing mode (REGURAR) that injects an appropriate amount of enzyme at a time to bring the inside of the treatment tank to 35 ° C with a small amount of air, and a large amount of air and heat in the treatment tank when the amount of waste input per hour is large High-demand mode (HI-DEMAND) that operates to bring the temperature to 35 ° C, the inside of the treatment tank is brought to 80 ° C, sterilized and sterilized continuously for 0.5-1 hour, and dried using the heat of the deodorizer Stabilized regular mode (STABLE), clean mode (CLEAN), which operates 100% open air until the waste before scraping the processed product into the storage tank is cooled, Things a certain blow mode to the operation to scrape savings tank (BLOW), and off mode only certain ventilation deodorizer (OFF).

  FIG. 9 shows a one-day operation mode time flow. The amount of dust generated changes with the passage of time, and the seven types of operation modes described above are switched accordingly. Such operation modes are accumulated and made into a database, and optimal control is performed.

  As is apparent from the above description, the waste disposal method and the waste disposal system of the present invention have the following structural features.

(1) By the stirring and the low temperature heating method of the processing tank, the upper space of the processing tank is suppressed and the total height of the processing machine is lower than that of the same capacity processing machine.
(2) The height of the inlet associated with the introduction of garbage is lower than that of a conventional processing machine by providing a receiving tank, and can be installed even at an average ceiling height of the garbage storage. A conventional method of conveying crushed waste of a processing machine uses a bucket type or a conveyor type, and is introduced from the upper part of the processing machine. As a result, an upper space for receiving the crushed waste is required more than the main body of the processing machine, the size of the main body of the processing machine is increased, and the ceiling height of a normal garbage storage is impossible, and the installation location is limited. By providing a receiving tank, the crusher could be installed sideways. As a result, it can be installed in a garbage storage with a normal ceiling height, and the installation location is not limited.
(3) Since the crusher is integrated with the main body of the processor, odor reduction and space efficiency are improved. By developing the functions of the receiving tank and the crushing waste transfer device, it was possible to integrate the crushing machine, which had been placed separately, by installing it next to the main body of the processing machine, improving the space efficiency. By integrating it with the main body of the processor, the deodorizer and crusher of the main body of the processor can be linked to reduce odor.
(4) A function of automatically discharging the processed product at a certain height was added to improve work efficiency. Conventionally, the function of discharging the generated residue has been scraped by a person from the lower part of the processing machine or by using a transfer device. In this machine, a scraping plate suitable for two types of properties, a high-viscosity processing product and a low-viscosity processing product, is attached to the processing product scraping paddle, and processing is automatically generated by setting the operation mode. Added a function to scrape things.
