2. Description of the Related Art
There have been few devices for easily pulverizing or using organic soil materials or soil contaminated with organic waste, agriculture, forestry and fishery by-products, and harmful substances. There was no simple device for detoxifying by treating in a reducing atmosphere. Although there were relatively large devices for continuous extrusion flow such as rotary furnaces and rotary crushers, small devices of this type which did not rotate the drum were difficult. As a device for composting or reducing the amount of organic waste, there are an input port for organic waste at the top of the stirrer, wood chips on which microorganisms have formed along with the organic waste, granular materials such as sawdust, and wood chips. Was charged and filled and stirred. In addition, a stirring mechanism for mixing and stirring the organic waste and the hard and porous spherical granular stirring medium in this stirring tank, a heating means for heating the inside thereof, and an air conditioning means for ventilating outside air are provided therein. was there. And
Some of the above-mentioned apparatuses have a mechanism for pulverizing organic waste, performing fermentation treatment and drying treatment to produce compost, and separating granular agitation medium particles.

[0003] However, since the stirring / crushing step, the drying or fermentation step, and the drying step as the composting step for composting organic waste and garbage are performed in the same place in the decomposition / stirring tank, the composting step is the most important. There is a problem in that when additional organic waste is added, it is mixed with each other and cannot be taken out until the additional composting is completed even if the first input is completed. Even in the case of an annihilation type operation, it was difficult to take out only the decomposition product. There was also a method of separating compost or decomposed product obtained by pulverizing the mixture by providing a perforated plate at the bottom of the tank. There is also a problem that the municipal waste also passes through the pores and is discharged into the decomposed product as immature compost or undegraded product. Moreover, in the conventional apparatus, the organic waste or the viscous organic waste that has not been dried to the extent necessary is deformed by the deposit pressure and the stirring pressure above it and adheres to the holes and the surface of the perforated plate, and the holes are clogged and cleaning work is performed. Had to be done frequently.

[0004] In addition, there has been a method of circulating hot water by means of external equipment to the decomposition / stirring tank for heating or keeping the temperature of the decomposition / stirring tank to enhance the activity of microorganisms. It is difficult to maintain the wall temperature at each position of the tank at the control temperature, it is difficult to cope with disturbances such as wind and rain, the heat efficiency is not good, and there is an odor problem.

Is a stirring rod, 23 is a stirring bar, 24 is a position adjusting cylinder or an angle adjusting mechanism, and 25 is an opening / closing door or a damper. In the present invention, the apparatus is a horizontal processing tank, the stirrer in the tank is a corresponding substantially horizontal transverse axis, and a new stirring rod structure, shape, and arrangement are adopted. The inlet of the organic waste to be treated is located at a position near one end, and a take-out position of the treated product or decomposition product is provided at a position near the other end. The tank is provided with a heater 6 as a heating means for heating the inside and an atmosphere conditioning means 5 for ventilating air or a regulated atmosphere. The exhaust gas may be circulated, and in the case of drying or microbial decomposition, harmful substances can be removed and steam can be adjusted to a necessary degree and refluxed. In this case, the odor and harmful substance removing device has an advantage that it can be miniaturized, and heat recovery and utilization become easy. For the removal of harmful substances, ultraviolet light decomposition, light / titanium oxide decomposition / ozone decomposition, and carbonaceous adsorbents such as activated carbon can be used. For heating or heat recovery, the inside of the decomposition / stirred layer and the outer surface are doubled and filled with water. The fermentation / decomposition heat generated inside the decomposition / stirring layer 3 is exchanged by heating with the corrosion-resistant heater 6 for water heating and stored and stored. The granular stirring medium 2 includes, for example, substantially spherical ceramics, angular pieces or rolling small pieces having sharp corners, a fine uneven surface 13 on the surface thereof, and a large number of communication pores (holes) 12 therein. In addition, the microorganisms for decomposing organic waste and the like are grown on the fine uneven surface portion 13 and the inner surface of the pore 12, and the excess water discharged from the organic waste 1 is temporarily absorbed and stored and released. At the same time, the organic waste is rapidly aerobicized while grinding the organic waste, and the bacteria are inoculated. It promotes anaerobic conditions as well.

[0009] The fine particles are finely divided by friction by the stirring movement of the stirring mechanism 4 and the hard porous granular stirring medium, and the decomposition products 14 containing compost and mineral effective components are generated by the activity of the aerobic microorganisms. It has been found that the granular stirring medium and the decomposition product 14 are dried by a predetermined stirring motion, air conditioning means, and a heating medium, and are classified into large to small ones in the axial direction of the stirring shaft. Due to this property, the relatively dry and fine decomposition product 14 and the granular stirring medium 2 form a zone separated from raw relatively coarse organic waste and the like. From the outlet 15, it was possible to take it out continuously in a limited manner. Semi-continuous or batch operation was also possible, and a zone could be formed in the tank as well. The decomposition product is not temporarily taken out in large amounts, and the granular stirring medium 2 is separated by the mesh sieve or the perforated plate portion 16 of the separation and storage mechanism 8, and the decomposition product 4
Falls below the sieve into the storage box 18, and the granular material stirring medium 2 is returned to the decomposition stirring tank through a return pipe or a gutter. An infrared or far infrared heater 19 for assisting drying is provided in the separation mechanism.
Then, the vibrator 20 for accelerating the feeding and the separation is provided. The heater prevents mesh clogging in synergy with the electric sieve.
In addition, if a part of the air-conditioning intake air is taken under the mesh from below the mesh and taken in a small amount, the separating effect and the clogging preventing effect are further enhanced. An air current flowing countercurrently on the net is also effective for drying. Heat sterilization and cooling are also possible. The exhaust air from the air conditioning or atmosphere adjusting means 5 is deodorized by the deodorizing mechanism 7 and then passes through the exhaust blower 25 and is discharged to the atmosphere. Moisture contained in the exhaust gas is collected by the deodorizing mechanism 7 or indirect cooling means in the form of condensation. In cold regions, it can be used to keep water tanks warm. In the case of exhaust circulation, an atmosphere gas recirculation pipe or an air recirculation pipe is provided.

One of the features of the present invention, classification by stirring and maintenance of a good atmosphere gas atmosphere or aerobic atmosphere are easy to control because of the arrangement of the stirring rod, the action of the stirrer, and the take-out port being located higher than the bottom of the tank. It is supposed to be. Experiments can determine the atmosphere in the decomposition tank and the arrangement for imparting the decomposition product separation performance. By setting the position of the stirring rod in a spiral shape, a multi-spiral shape, or a relatively close interference position, and thus the position of the stirrer is also correspondingly arranged, processing zones having different functions can be configured. The stirrer may be, for example, an elongated bar or strip-shaped plate arranged and processed into a lattice or fork shape with the tip of the stirrer rod processed. The stir bar is moving the stir bar at a certain interval. In this way, the stirring effect, the shearing effect of the stirrer, the crushing effect, the classifying effect, etc. work, and the movement of the lumps and grains in the mixture causes pulverization and separation depending on the moisture, particle size, specific gravity, and the action of bacteria. . This condition is based on the fact that the effect differs depending on the deposition pressure, particle size, and material distribution depending on the axial position and height position in the tank. The preceding stirring rod and stirrer press the organic waste and the like against the group of granular stirring media, and the crushing force and the crushing force, as well as certain sieving, simultaneously act strongly in each treatment zone, particularly in the zone near the inlet, by separating. The crushing and grinding actions are different from those of a ball mill. Even lighter,
It also differs from the action of soft wood chips.

In addition, in a place where the scraped-up granular stirring medium rolls and moves, it also functions as a ball mill. A grid-like, multi-layer plate or sieve-like stirrer is used to separate dry granules with specific gravity, separate particles and scrape them up. The sedimentary layer is partially sparsely scattered with the drying action, moving while causing particle size separation, fine grains move up, coarse grains spill down or down, and fine grains float. It moves so as to collapse to the exit side, falls on a sparse part created by a stirrer at a virtual spiral line or a staggered position, and the stirrer at the following position pushes the mixture into the sparse part formed by the preceding stirrer, At this time, the light particles float, the water content is relatively high, the relatively coarse heavy particles sink, and the lifted particles fall diagonally to the cavity or sparse part created by the stirrer that follows. It is presumed that by repeating this operation, the particle size distribution and the separation could be formed as a result. Alternating alternation, movement and rolling are also provided as a switching operation to improve the contact between the air or the atmosphere and the mixture and to keep the entire layer aerobic in an air atmosphere. For deodorization and removal of harmful substances, good contact with the atmosphere or an atmosphere additive such as a neutralizing agent is provided. The decomposed material part rich in dry small particles which has floated to the outlet height by the scraping, the particle size and the specific gravity separation is discharged, and the granular stirring medium is separated smoothly. Such a classification method has not been known before. Therefore, the band is constituted by a relatively short axial length, and the separation of the organic waste and the microorganism-treated dried product which are almost raw is facilitated.

The granular stirring medium to be filled in the tank is suitably an apparent specific gravity of about 1.2 to 2.3 and heavier than the object to be treated. Grinding power decreases. A diameter of 3 mm to 15 mm is suitable in terms of weight and grinding surface area, but a small amount of coarse material may be mixed. However, if there are too many particles having a large particle size, in the case of aerobic treatment, many anaerobic portions are formed at the center of the particles, which sometimes causes an unpleasant odor.
Conversely, finer particles are undesirable because they are difficult to separate from organic waste products. It is desirable that the surface of the granular stirring medium has a fine uneven surface, and it is easy to implant microorganisms, and the grinding effect can be enhanced by an increased water absorption area and a rough and hard surface. The diameter of the communicating pores forming the inner surface of the granular material is preferably around 50 microns on average, and the pore size distribution is preferable. It has a large internal surface area, promotes moisture penetration, has a large amount of microorganisms, and prevents the penetration of fibrous plugs. it can. If the pore size is too large, the effective internal surface area as a microbial bed will be reduced, and if the pore size is too small, the pores are likely to be clogged, water absorption and dehydration will not be smooth and anaerobic, and the effect of improving sediment permeability will be poor. become. The granular agitation medium is different from wood chips and the like in that the particle density is heavier than the organic waste, and is stirred up and settled in the tank by the agitation, and at the same time, exerts a grinding force. It is desirable to have a small wear loss.

The decomposition product is sieved by the sieving mechanism at the outlet, and the granular agitation medium can be greatly reduced by returning the granular agitation medium to the tank. The high-strength granular agitation medium, combined with the morphological stability and the great crushing effect, combined with the product refining, can avoid the useless increase of the decomposed product due to the loss of transfer of the supplement to the decomposed product as in other methods. In the present invention, one year
Two or more replenishments of the granular stirring medium of about 10% are sufficient, and the amount of compost or decomposition products can be reduced to less than half that of the conventional method.
On the other hand, in the case of organic soil formation, it is not necessarily required to be hard, and a moderately water-resistant and porous material such as a crushed brick or a surface processed product thereof may be used. In addition, it may be appropriately worn during use to utilize the rolling property and the crushability of the corner. The material may be a mixture of a non-porous granular stirring medium and a porous granular stirring medium of alumina, clay, iron oxide or the like, or vitreous, rock, or volcanic ash. These can be manufactured by tumbling granulation, fluidized granulation, extrusion cutting, crushing or a combination thereof and sintering or cement binder, and it is possible to add tumbling operation and surface sintering to increase surface strength or squaring. It is necessary that it is water-resistant, hydrophilic or non-water-repellent, and that it has substantially no toxicity to bacteria and living organisms, as described above. It may be a porous natural product, processed product, shard, or the like having the above properties. What sharply decreases the strength after surface peeling is not preferable depending on the degree.

The atmosphere in the tank or the air-conditioning air flow rate is 0.2 to 10 per cubic meter of the tank volume depending on the operating temperature in order to remove generated moisture and maintain an aerobic atmosphere in the tank.
The range of cubic meters is appropriate, and it is preferably about 0.4 to 7 cubic meters / minute per cubic meter of the granular material.
Conditions can be easily set from low to relatively high depending on the quality, quantity, product status, and operating temperature of the input waste. The temperature inside the tank should be higher than 15 ° C and the activity of bacteria is 80
C. or lower, preferably 25 to 50.degree. C., particularly around 45.degree. In this case, a feature in which a plurality of types of bacteria act simultaneously is used. When the temperature is around 60 ° C. or higher, the pasteurization temperature is reached.

The most striking feature of the device of the present invention is exhibited when operating at around 15 ° C to 45 ° C. In other words, compared with the conventional type that does not separate at the decomposition product discharge port that uses a replenishing material such as wood chips, sawdust, etc., there is less restriction on organic waste and air or circulating gas supply to adjust the atmosphere or aerobic air conditioning in the tank. To do it. Thus, excessive moisture and nitrogen compounds such as ammonia are quickly expelled from the tank to promote the growth of microorganisms, accelerate the decomposition of organic substances, and reduce the compositional restrictions of organic wastes. In this way, it becomes fine granules 2 hours after the introduction, and becomes compost and feed with a dry residue amount of 10 to 15% in 24 hours. It has properties suitable for soil bacteria and living organisms.

[0016] The water in the jacket is obtained by transferring heat from a remarkably heated portion to the jacket or the water tank due to the particle size distribution and material distribution in the axial direction and the vertical direction in the tank, and heat transfer by scraping by the stirrer. Heat is removed, and heat is supplied to a portion where the heat becomes insufficient due to the drying heat to promote heat exchange drying, thereby achieving appropriate temperature distribution or uniformity to prevent local overheating and cooling. Excess heat is removed as drying heat out of the system by air conditioning. In order to maintain good operating conditions or fermentation conditions, it is preferable to measure and adjust by using a plurality of heaters 6 for heating water and temperature sensors 28 in a water tank and a plurality of points in the tank. When a set temperature is distributed, heat exchange is promoted by heat convection. it can. The composition, moisture, quality, input amount, input speed,
Product quality and yield can be easily controlled while measuring and considering the outside air temperature, atmospheric gas or air temperature, circulating gas amount, and processing results. The atmosphere gas may be combustion exhaust gas, carbon dioxide gas, nitrogen, and sometimes an additional gas such as a reducing gas, a neutralizing agent, and ozone.

In FIG. 1, the organic waste or the like introduced from the inlet 9 is a stirring rod (connecting rod) 2 provided with a stirring bar 23.
In step 2, the granular stirring medium 2 in the tank is mixed with the organic waste being decomposed at the entrance, mixed, crushed, crushed, and heated to adjust the excess water to start and advance fermentation. The stirrer may be attached to the tip of the connecting rod or by processing the tip of the stirring rod. The tip of the stirrer is located where the bottom and wall parallel to the stirring axis can be scraped off. A feed wing, a push-back wing or a weir may be used in combination, and a particle size distribution and a material distribution can be provided in the vertical and horizontal directions. Equipment conditions can be determined by testing. The mixture of the decomposed product and the granular stirring medium, which has been fermented or dried and eliminated, is adjusted from the discharge port 15 as an outlet by adjusting the opening / closing door or the damper 25 with the position adjusting cylinder or the angle adjusting mechanism 24 as necessary to adjust the amount of the outflow. It is discharged to the electric sieving machine 20, and it irradiates by irradiating while controlling the temperature preferably by the far-infrared heater 19 while continuously flowing down the gutter so as not to overheat. The mixture is sieved while preventing clogging, and the dried granular stirring medium is returned to the pipe 1
7. Return to the input side of the decomposition / stirring tank 3 via the return blade 21. This dry granular agitation medium can rapidly absorb and control the water content of the organic waste. The separated decomposition product is stored in the storage box 18. It is desirable to control the temperature to prevent overheating of the far-infrared heater or to sterilize by heating, and to install an interlocking circuit for the power supply of the electric sieving machine in order to prevent degradation of the decomposition products.

In FIG. 4, the high and low distribution in the decomposition / stirring tank 3 has a large amount of water and the coarse organic waste input port 9 is large.
Is provided at a relatively high position so that it can be charged even if the deposition height is high. The outlet 15 may be provided at a high position or at an arbitrary height, and a plurality of inlets and outlets may be provided. It is convenient to make the removal and sieving function adjustable in height and tilt. In organic waste treatment, the input material from the inlet is rolled down to a low level, and is caught in the group of granular stirring media, crushed, dehydrated, and fermented to make it porous and lightweight, and pushed out to the outlet side to continue fermentation The fermentation is finished near the outlet to dry and granulate. Drying or removal of harmful substances can be similarly performed. FIG. 3 shows an example of a granular agitation medium.
In the schematic diagram of the pore group 12 of the partial cross-section and the internal partial cross-section, the granular sintered body may be a maze-like communicating porous substance. In the distribution of the deposit height at the outlet side, the slope promotes air or atmosphere conditioning and drying by renewing the deposit surface, and the composition of the mixing zone contributes to uniform quality. According to the present invention, a new stirrer structure, a combined effect of grinding and crushing action by a granular stirring medium for taking out / separating decomposed matter and a microorganism-retaining particulate stirring medium, heat transfer of a water tank, atmosphere adjustment or air conditioning, decomposed matter taking out position , Fermentation, removal of harmful substances, etc. are promoted by the combination of selection of supply / exhaust position, etc. and maintenance of the optimum temperature, and the processing time is shortened. If it is heavy, it can be selected from a wide range such as clay or other soil, ash, brick pieces and the like.

EXAMPLES Example 1: Width 2.7m, depth, height 1.
In a 3 m apparatus, garbage (moisture average: 80%) was treated at a daily dose of 100 kg. It was found that the raw garbage disappeared within 2 to 3 hours after the introduction, and that the contamination of bacteria and the start of the activity could be promoted. The heating heat source becomes unnecessary in 4 to 5 hours, and the digestion is completed in 10 hours. If necessary, the degree of drying can be increased by residual heat over 24 hours. Bath temperature 4
Using bacteria active at 0 ° C. and around normal temperature, the number of rotation of the stirrer is 2.
The rate was set to about 3.5 cubic meters / minute at a rate of 5.6 cubic meters / minute at a maximum of 5.6 cubic meters / minute. The granulated agitation medium is 90% of 3 to 9 mm in diameter by rolling granulation of alumina powder.
The spherical sintered body was 15% in porosity and had an average pore diameter of 50 microns, and was filled with 700 liters. When cooked garbage was charged with continuous stirring, about 50 kilograms were charged in the morning and night, and continuous operation could be performed day and night. It was safe to throw in 100 kilograms at a time. Yield is 3 to 15% depending on the purpose such as the quality of organic waste and compost or feed, reduction of fertilized soil, etc.
Could be adjusted within the range. A dried product having a water content of 8 to 20% without rotting odor and garbage odor was obtained. In the case of mixing of raw garbage components and rice husks and straw as a compound, those which can be used as compost, horticultural soil conditioner, and feed contaminants were obtained. Deodorization of the exhaust gas was small, and deodorization was easy particularly when the exhaust gas was circulated. The maximum power was 3.3 kW. 10% after 150 days of operation without replacing the ceramic granular stirring medium
Operation could be continued with only replenishment. The garbage component was almost irrelevant to the treatment capacity and did not need to be adjusted. A small device at 30 kilograms / day performed similarly. A wind box for circulating exhaust can be provided outside the water tank to enable heat retention and moisture condensation, supply air heating and operation in cold regions. Brick debris, gravel,
Iron oxide reduced pellets could also be used alone or as a mixture as a granular stirring medium.

(Comparative example): In the conventional simple stirring method using no inorganic granular stirring medium, the mixed type in which rice hulls, sawdust, wood chips and the like are added as a fungal base material, the raw garbage remains for several hours to several days. There was a case. In addition, in the conventional type, the added base material needs to be replaced once every one to two months.
The yield was 0 to 30%, and the rate of weight loss was poor. There are also restrictions on the garbage components that can be treated, and operation was difficult with excess protein. For example, for vegetable garbage 10, there was an appropriate range of 0.5 to 3 for nitrogenous garbage such as fish. The heat source and power required a maximum of 7 kilowatts x 24 hours at 100 kilograms / day treatment. A perforated plate separation function was attached to the bottom cleaning port using an alumina-based spherical stirring medium, and an emission test was performed. The undecomposed material was severely clogged and the perforated plate was broken.

Example 2 The apparatus of Example 1 is used to mix organic odorous sludge, i.e., channel sludge and landfill mud, with garbage,
Each was treated in the same manner as in Example 1 to obtain an odorless earth-like material.

[0022]

According to the apparatus of the present invention, the decomposition treatment of organic waste such as fish, vegetables and other garbage can be achieved by a simple treatment operation while greatly reducing the volume. The decomposition products of organic wastes can be used in a wide range of applications and disposal destinations from compost and soil fertilizing components to feeds, have a high volume reduction rate, and can easily treat soil containing harmful substances.
