DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic waste processing apparatus for decomposing and treating organic wastes while stirring them in a processing chamber.

[0002]

2. Description of the Related Art Conventionally, a garbage disposer for decomposing a treated substance composed of organic waste discharged from a home or a kitchen has a microbial bacterium as an accelerator for accelerating the decomposition action of the treated substance in a treatment chamber. (Degrading effective bacteria) and a medium (adjusting material) such as sawdust are mixed and accommodated as a base material, and a processed material is supplied into the base material and both are stirred and mixed by a rotary stirrer or the like. In addition, the microorganisms are multiplied and held to decompose the treated product. In addition, the processing apparatus using the above-described microbial bacterium as an accelerator is configured to control the activity of the microbial bacterium, such as an intermittent rotation control unit for the stirring body, and a temperature control unit adapted to the degree of microbial growth. However, there are disadvantages that the apparatus becomes complicated, the operation is complicated, and the disassembling process takes a long time.

[0003] In recent years, as a technique for solving the above-mentioned drawbacks, a promoter is used as a biological mineral extracted from a living organism, and a holding material containing the biological mineral in a mineral such as ceramic or zeolite is mixed with an adjusting material. By providing a base material that can easily form a suitable environment for microbial bacteria by the action of biological minerals, and by stirring and mixing the processed material in the base material, a short-time decomposition treatment can be performed with a simple configuration and operation. A processing apparatus adapted to perform the processing has also been proposed.

[0004]

However, as described above, the conventional processing apparatus for supplying microbial bacteria as an accelerator requires the adjustment of the stirring time and the temperature, etc., in order to make the microbial activity suitable. It is extremely complicated, and it is difficult to always maintain a constant processing performance due to the heat generated by the microbial bacteria. There are drawbacks that easily give large fluctuations in the processing, and because of the long processing time and the difficulty in using a sterilizing power adjusting material,
The frequency of insufficient treatment of processed materials is extremely high,
In such a case, there are problems such as frequent occurrence of bad smell and fly, and generation of sewage at the bottom of the processing chamber.

[0005] Further, a processing apparatus using a holding material in which biological minerals are contained in minerals such as ceramics as an accelerator,
The processed product can be decomposed in a shorter time than the above-mentioned conventional one, and there are advantages such as less generation of offensive odor at that time. Then, since the appropriate amount of the processed material with respect to the amount of the base material becomes unbalanced, there is a problem that the microbial activity is not sufficiently performed, the decomposition processing time is increased, and the odor component in the gas generated during the processing is increased. . Therefore, there is a demand for a processing apparatus capable of efficiently and satisfactorily processing a large amount of processed materials while reducing the size.

A mounting bracket 29 bent upward is provided on the outer periphery of the top plate frame 29.
a, the frame rigidity of the processing apparatus 1 can be improved with a simple configuration, and the above-described devices and the like disposed around the processing tank 2 on the top plate frame 29 can be improved. The equipment can be mounted and supported stably. In addition, reference numeral 28a denotes an opening which is opened and closed by the lid 28.

In the processing apparatus 1 having the above-described machine frame structure, since the processing tank 2 also serves as a support frame for firmly supporting the top frame 29, a special outer frame or the like is required for mounting covers. The machine side cover 11 can be attached and detached with the mounting bracket 29a formed on the outer periphery of the top plate frame 29 and the machine base 10 because there is an advantage that a simple and inexpensive structure can be made unnecessary. The top plate cover 12 is detachably attached to the tank top plate portion 26 and the mounting bracket 29a above the top plate frame 29.
Thereby, each device is compactly covered in a space around the processing tank 2.

The processing chamber 2a constructed as described above has a bottom plate 2b having a lower outer periphery of a rotation locus of a pair of agitating bodies 3 which are close to and opposed to each other as shown in FIGS. And a temperature sensor 1c capable of detecting the processing temperature in the processing chamber 2a is attached to the right side wall 20 adjacent to the peaks of the two curved surfaces. On the back side of the bottom plate 2b, the inside of the processing chamber 2a is maintained at approximately 30 ° C.
A heater 1f capable of heating in a range of 60 ° C. is attached, and the heater 1f is provided with a temperature sensor 1a and a control box 1c.
Can be set to a desired set temperature.

The processing chamber 2a is provided with an air supply pipe 51 of the hot air supply mechanism 5 from the left side wall of the tank top plate portion 26 at substantially the upper portion of the middle of the stirring members 3 provided in the front and rear directions. A slit-shaped air supply nozzle hole 52 having a width of about 1 mm is provided on the entire lower surface of the air supply pipe 51 so as to extend horizontally across the width.
Is formed so that hot air can be blown from the air supply nozzle hole 52 toward the top of the chevron of the bottom plate 2b in a downward air curtain shape. As shown in FIGS. 5 and 10, the hot air supply mechanism 5 includes the air supply fan 50.
An air supply heater 55 mounted and supported on the back side of the top plate frame 29 is provided in the middle of a connection pipe 53 connecting the air supply pipe 51 and the air supply pipe 51, and the air supply pipe 51 is heated while air supplied by the air supply fan 50 is heated.
As described above, the temperature inside the processing chamber 2a is set to a processing suitable temperature of about 45 ° C., and when the processing state of the processing object W is in the excessive water state, the evaporation of water is stopped. The humidity sensor 1b can be automatically operated by controlling the humidity sensor 1b, or manually operated by the operation panel 1e.

Above the processing chamber 2a, a water supply pipe 42 having a plurality of water supply nozzle holes 41 of the water supply device 4 at coarse intervals is provided.
From the left side wall of the tank top plate 26,
Water supply pipe 4
2 is connected to the mineral water generation tank 40 through an electromagnetically operated switching valve 43 in the middle, and the upstream side of the mineral water generation tank 40 is connected to, for example, a water pipe 45 installed in a building. The water is supplied. As shown in FIGS. 5 and 12, the water supply device 4 configured in this manner directs the mineral water downward from above the middle part of both agitators 3 in the processing chamber 2 a by the water supply nozzle holes 41 by operating the operation panel 1 e. By spraying in the radial direction, it is possible to uniformly supply moisture to the processing object W during stirring, and when the processing object W or the like is dry, the humidity in the processing chamber 2a is quickly increased to increase the microbial germs. It can provide a suitable environment, promote the activity of microorganisms, and promote the decomposition treatment of the processed product W with mineral components.

The mineral water generation tank 40 of the embodiment
As shown in FIG. 10, the filter member layers 4a, 4a,
An activated carbon layer 4b is installed, and a biological mineral ceramic layer 4c in which a large number of ceramic grains containing biological minerals are stacked is provided above the activated carbon layer 4b. Water from which impurities have been removed by the filter member layer 4a and the activated carbon layer 4b is used to remove water. By passing through the mineral ceramic layer 4c, a biological mineral component serving as an accelerator is provided and supplied into the processing chamber 2a. Therefore, when the water content is adjusted while stirring the processed material W in the processing chamber 2a, the mineral water containing the accelerator composed of the biological mineral that promotes the decomposition action of the processed material is supplied by the water supply device. It is possible to easily maintain the suitable environment for microbial bacteria in the processing chamber at the same time as the supply of the accelerator and the replenishment of the accelerator at the same time, and it is possible to perform the decomposition treatment of the processed material by the microbial activity well. There are advantages. Incidentally, the application of the mineral component to water is not limited to the above-mentioned means. Further, the processing apparatus 1 in this embodiment uses biological mineral ceramics as the promoter S, but is not limited to this, and treats the processed product W with a conventional promoter mainly composed of specific microorganisms. Is also good.

As shown in FIGS. 2 and 4, the processing chamber 2a has an exhaust port 61 communicating with an exhaust fan 60 of the deodorizing exhaust mechanism 6a on the left inner side wall of the tank top plate 26. As described above, the supply air spouting downward from the air supply pipe 51 is sufficiently blown against the processed material W and the base material being stirred by the stirrer 3 to quickly create an aerobic environment suitable for microbial activity. While providing the gas, the gas with the odor generated during the processing is moved upward through the exhaust port 61, and can be discharged while being properly sucked out so as to be separated from the new air supply.

That is, the hot air supplied in the form of an air curtain from the air supply nozzle hole 52 of the air supply pipe 51 is supplied to the processing target W which is being stirred.
, And the hot air is sequentially supplied and the exhaust fan 60
, And is well pushed out and sucked out while being prevented from being mixed with the new hot air to the exhaust port 61 located above the processing chamber 2a which is separated from the air supply nozzle hole 52 and the other side. That is, even in the relatively small processing chamber 2a, mixing of the hot air and the gas can be prevented, so that the processed material W can be decomposed as quickly as possible, and Since the gas can be quickly discharged and accurately sent to the deodorizing and exhausting mechanism 6a, where the odor component can be removed and then smoothly discharged outside the machine, a large amount of gas can be obtained even if the processing apparatus 1 is downsized. The advantage is that the treated product W can be efficiently decomposed.

As shown in FIGS. 5 and 8, the processing chamber 2a
Forms an outlet 20a at the lower part of the right side wall 20 from which the processed product W can be taken out, and the outlet 20a
Cover 20b which is openably and closably attached to the outside of the side wall 20
The opening and closing operation of the outlet lid 20b can be easily performed from a wide space formed below the control box 1c, and the work W to be processed and taken out can be easily performed. Have to be able to.
The outside of the outlet lid 20b is openably and closably covered with a palate cover 20c attached to the machine side cover 11.

Next, the agitator 3 will be described with reference to FIGS. 6, 11 and 12. FIG. The agitator 3 has a rotating shaft 3
Stirring rod 31 provided at the tip of stirring rod 31 from both sides of
The two agitating rods 31 erected on both sides of the rotating shaft 30 and the two agitating rods 31 at the center are arranged at coarse intervals over the shaft circumference so that the two helical trajectories 2 and 33 draw two spiral trajectories. The stirring rod 31 is connected and fixed by a belt-like stirring blade 32, and a short plate-like stirring blade 33 is attached and fixed to the other stirring rod 31 in the middle. Further, the stirring body 3 is provided with a stirring rod 31 at the right end.
When a stirring blade 35 is provided at the tip of the opening and the outlet cover 20b is opened, the processed product W is discharged from the outlet 20a through the stirring blade 3
5 can be pushed out to promote discharge.

When the two rotating shafts 30 are rotated in the direction of the arrow by the drive mechanism 22 as shown in FIG. 6 by the structure of the stirring body 3, the pair of stirring bodies 3 become the stirring rod 31 and the stirring blades 32, 33. While the workpiece W and the base material are agitated and mixed by the spiral trajectory, the two are processed in the processing chamber 2 in plan view.
In the area a, vortex-like convection (swirl) in the direction of the arrow can be performed to promote uniform stirring and mixing, and the decomposition of the processing object W can be improved. Also, at this time, the stirring blades 32 on both sides are belt-shaped and rotate close to each other along the curved surface of the bottom plate 2b, so that stagnation of the workpiece W or the like at the corner portion of the processing chamber 2a having a large rotational movement resistance can be accurately prevented. In the center of the shaft, the short stirring blade 33 and the stirring rod 31, which are standing independently, tend to be carried around in a nodular form when the water content is high and the viscosity is high. The loosening / stirring action between the processed material W and the base material is promoted, and the loosening / stirring action at this time is not accompanied by a large resistance.

Next, an ozone deodorizing device 6 for the primary deodorizing process and a photocatalyst for the secondary deodorizing process for removing the odor components in the gas in the discharging process of discharging the gas generated during the processing from the exhaust port 61 of the processing chamber 2a. Deodorizing exhaust mechanism 6 including deodorizing device 7 and the like
a will be described. First, as shown in FIG. 9, FIG. 10, and FIG. 13, the ozone deodorizing device 6 includes an air supply port 62 for supplying gas containing an odor component discharged from the processing chamber 2a and an exhaust port for discharging deodorized gas. Water for aeration is stored up to an intermediate portion in a rectangular box-shaped closed tank 65 having a space 63, and a space is formed above the water surface.
An air supply pipe 6 connected to an air supply port 62 for supplying gas to the gas supply port 0
6 and an ozone tube 68 for supplying ozone gas through an ozone generator 67 provided with an air pump 67a are provided so as to be polymerized with a predetermined bubble diffusion interval above and below the stored water.

The air supply pipe 66 is provided with a plurality of ejection holes 66a in the tube direction below the center of the cylindrical tube, and at the radial position close to both sides of the ejection holes 66a at the center.
A plurality of similar ejection holes 66a are formed in the pipe direction, and gas is ejected from the center of the lower surface of the air supply pipe 66 and the sides thereof as shown in FIG. While substantially evenly spreading to both sides, the residence time in water is made as long as possible.

Further, as the ozone tube 68, a sintered metal tube capable of forming fine holes of several tens of microns in the entire circumference of the tube is used. So that they are generated and transmitted uniformly,
The rapid rise of ozone bubbles in water can be suppressed and the residence time in water can be lengthened, and the entire gas bubbles can be uniformly aerated for a long period of time. The odor components can be efficiently decomposed.

In the space formed on the water surface in the tank 65, a plate-shaped partition plate 69 is provided so as to project upward and downward from opposite sides of the side wall 65a so as to partition the space. By forming the bent discharge processing path 6b between the end of each partition plate 69 and the side wall 65a, a series of narrow discharge processing paths 6b whose vertical height from the water surface to the discharge port 63 is low is low. It is formed. With this configuration, the bubbling caused by the rise of the gas bubbles and the ozone gas bubbles mixed with the gas bubbles suppresses the ripples and splashes which are generated violently on the water surface by receiving the lower partition plate 69 close to the water surface on the back surface. Discharge processing path 6b
It is possible to prevent the water from directly moving to the side, to promote the reaction with the ozone gas in the space above the water surface, and to properly prevent the splashed water from reaching the discharge processing path 6b. .

The gas aerated by mixing it with ozone gas of minute bubbles in water can greatly remove odor components, and can further remove the processed product W and mother material that have been excessively dried in the processing chamber 2a. When the material is in powder form, even a minute amount of dust that is sent out in the gas by the exhaust fan 60 can be satisfactorily removed in the water by the aeration effect. The removed gas is transferred, so that it is possible to satisfactorily prevent the gas from contaminating and clogging the catalyst curtain 75 and the like described later. Next, the gas and the ozone gas rising from the water surface are mixed and move over the refracted narrow discharge processing path 6b while changing the flow path, so that the gas flows as in the conventional ozone deodorization and exhaust mechanism. Since the gas is not directly discharged from the space on the water surface to the discharge port 63, the odor components remaining in the gas can be further decomposed, and the ozone can be sufficiently attenuated and eliminated. There is.

In this embodiment, the ozone deodorizing device 6 is used.
The water stored in the water supply device 4 is configured such that the mineral water produced in the mineral water generation tank 40 of the water supply device 4 is supplied at a constant rate via a water supply pipe 47 branched from the water supply pipe 42 and stored. The water supply structure of the water containing the mineral component can be used simply and inexpensively by also using the water supply device 4 of the treatment chamber 2a, and the stored water is kept clean for a long time by the water purification action of the biological mineral component. There are advantages such as being able to do.

Next, the photocatalytic deodorizing device 7 will be described with reference to FIGS. This photocatalytic deodorizing device 7
Is provided with a lid box 71 which can be opened and closed by a suitable fixing tool such as a mounting screw in a rectangular box-shaped container 70 having an open upper side to form a closed deodorizing chamber 7a. An air outlet 72 connected to the outlet 63 of the ozone deodorizing device 6 is provided on the upper side of the chamber 7a in the exhaust direction, and an outlet 73 for discharging the deodorized gas is opened to the outside on the other side. I have. In the deodorizing chamber 7a, a catalyst curtain 75 having a gas permeability while having a photocatalyst of titanium dioxide is provided.
A plurality of rod-shaped lamps 76 of an ultraviolet irradiation type, which are arranged in a plurality of rows so as to form an exhaust path 7b of a predetermined width while blocking in the vertical direction along the exhaust direction of the gas, and generate a catalytic action of a photocatalyst, Both ends are detachably supported by a socket portion 76a vertically provided on the mounting bracket in the longitudinal direction on the back side of the plate 71, and are accommodated and installed in a central portion in the deodorizing chamber 7a.

As shown in FIG. 16 (B), the catalyst curtain 75 shown in FIG. 16 is prepared by converting titanium dioxide into glass fiber provided with a photocatalyst by a fixing means such as coating or baking beforehand. Bundled into a warp 7c and a weft 7d to form a filter-like curtain provided on the entire surface with a gap 7e that can be ventilated by the warp 7c and the weft 7d woven in the vertical and horizontal directions. The width is substantially the same as the width, and the vertical width is shorter than the vertical width of the deodorizing chamber 7a, so that an exhaust path 7b is formed between the deodorizing chamber 7a and the inner wall surface. The catalyst curtain 75 in the illustrated example has a notch formed with two lamps 76 attached to the cover plate 71 so that the front end side of the flat plate-shaped curtain body is inserted from one side, and the outer periphery thereof is formed. Is clamped and supported by mounting screws 7h while being sandwiched between the supporting frames 7g from both sides, and the base side of the supporting frame 7g is supported on the lid plate 71 and the container 70 side at equal intervals by the following mounting structure. At the same time, a pair of bent exhaust passages 7b in the deodorizing chamber 7a is fixed by attaching and fixing the opposed catalyst curtains 75 in the closed state of the cover plate 71 so as to be inconsistent with the two lamps 76 being fitted. Can be easily formed.

The mounting structure of the catalyst curtain 75 includes two mounting rods 7 detachably supported on the cover plate 71 and the bottom of the container 70.
7, a plurality of gap adjusting collars 78 which are removably fitted to the mounting rod 77, nuts 79 which are screwed into screw portions formed at both ends of the mounting rod 77, and the like. A mounting hole is formed on both sides of the base of the mounting member 75 so as to be removably fitted to the two mounting rods 77. With this configuration, the catalyst curtain 75 in the illustrated example can be obtained by tightening the nuts 79 at both ends with three collars 78 inserted between the adjacent catalyst curtains 75 inserted into the mounting rod 77. A plurality of catalyst curtains 75 are erected and supported at substantially equal intervals, and the exhaust passage 7b is provided by displacing and providing opposed catalyst curtains 75 in the center of the adjacent catalyst curtains 75 so as to be respectively installed. It is formed in a series. In the exhaust passage 7b, the interval between the catalyst curtains 75 can be easily changed by changing the length of the collars 78 or increasing or decreasing the number of the collars 78 between the catalyst curtains 75. There are advantages that the photocatalytic deodorizing device 7 adapted to the capacity and the size of the deodorizing chamber 7a can be manufactured at a low cost with a simple configuration.

Accordingly, the photocatalytic deodorizing device 7 configured as described above compactly combines a plurality of gas-permeable catalyst curtains 75 erected from the lid plate 71 side and the container 70 side in the closed deodorizing chamber 7a. Since the exhaust passage 7b is bent in a plurality of stages and the lamp 76 is installed at the center of the deodorizing chamber 7a, the light emitted from the lamp 76 is applied to each catalyst curtain. 75 can efficiently receive and activate the photocatalysis. Therefore, in this state, the gas sent from the air supply port 72 sufficiently repeats the contact with the photocatalyst while bypassing each catalyst curtain 75 when passing through the exhaust path 7b.
Since the gas passes through the gap 7e or passes between the glass fibers, the gas exhaust resistance can be reduced as much as possible, and the gas can be brought into good contact with the photocatalyst. Therefore, the decomposition of the odor component in the gas by photocatalysis can be promoted, and the gas from which the odor component has been removed can be quickly discharged to the outside of the machine.

At this time, the photocatalyst deodorizing device 7 is provided with the ozone deodorizing device 6 on the upper side in the exhaust direction, and is configured to perform the primary deodorizing and then the secondary deodorizing. The gas sent in a state where dust and the like have been removed can be prevented from contaminating the catalyst curtain 75 and clogging with dust, and the gas deodorizing treatment performance of the catalyst curtain 75 is improved. Therefore, there are advantages that the pumping speed can be increased and that the photocatalytic deodorizing device 7 can be easily miniaturized.

When performing maintenance work such as replacement and cleaning of the lamp 76 and the catalyst curtain 75, the photocatalytic deodorizing device 7 having the catalyst curtain 75 in which the groove 7f is formed is provided by the cover plate 7
14, the catalyst curtain 75 and the lamp 76 on the cover plate 71 side can be taken out together, and the interior of the deodorizing chamber 7a can be opened. The maintenance work of the curtain 75 can be performed efficiently and easily. In addition, catalyst curtain 75
Is supported by the support frame 7g, so that the above-described mounting and support can be easily performed, and the cloth-shaped curtain body does not swing due to the gas flow rate or the like. The abrasion can be prevented well, and the durability of the catalyst curtain 75 can be improved.

Next, the manner of processing the workpiece W by the processing apparatus 1 configured as described above will be described. First, the processing object W is supplied into a base material including a predetermined amount of the accelerator S and the adjusting material N accommodated in the processing chamber 2a, and the heater 1f is turned on to set the processing chamber 2a to a processing temperature of about 45 ° C. The agitator 3 is operated in this state, and the water content is adjusted by supplying mineral water by operating the water supply device 4 so that the water content in the processing chamber 2a becomes approximately 60 to 70% by the detection instruction of the humidity sensor 1a. Do. Thereby, as shown in FIG. 6, the processed material W and the base material are stirred while being convected by the pair of stirrers 3 in the direction of the arrow, and are mixed well, thereby creating a favorable environment for the growth of microorganisms by the promoter S. The decomposition of the processed material W is promoted.

At this time, as described above, the water supply device 4
When moisture is adjusted, as shown in FIGS. 5 and 12, mineral water is jetted downward from above each water supply nozzle hole 41 from above the middle part of both agitating bodies 3 in a radial direction, and the processed material W being agitated. And water can be supplied uniformly to the processing chamber 2
It is possible to quickly raise the humidity in a, create a suitable environment for microbial bacteria, activate the microbes, and promote the decomposition treatment of the processed product W with mineral components.

The hot air supply mechanism 5 includes a humidity sensor 1b.
Is activated when it detects that the humidity in the processing chamber 2a is higher than the set value, and hot air is blown between the pair of agitators 3 through the air supply nozzle hole 52 formed in a slit shape of the air supply pipe 51. Since the air is supplied in a uniform manner, the processing material W and the base material, which are separated and separated by the stirring bodies 3 on both sides, can be blown accurately and efficiently in contact with the processing material W and the base material. Since the gas containing moisture and odor components is exhausted from the exhaust port 61 by evaporating the water, the predetermined humidity can be constantly maintained, and the predetermined temperature and humidity suitable for the activity of the microorganism can be maintained. The decomposition action of the processed product W can be promoted, and the decomposition process of the processed product W can be performed in a short time as possible.

In addition, new hot air is sequentially supplied to the processing chamber 2 a, and the exhaust fan 61 sucks the exhaust air from an exhaust port 61 provided on the other side of the air supply nozzle hole 52.
Since the gas can be quickly discharged while preventing the gas from being mixed with the hot air, the processed gas is favorably maintained in the aerobic environment without stagnation in the processing chamber 2a and discharged from the processing chamber 2a. The gas is supplied to the ozone deodorizing device 6 of the deodorizing and exhausting mechanism 6a, where the gas is subjected to the primary deodorizing process, and then subjected to the secondary deodorizing process by the photocatalytic deodorizing device 7, so that the odorless gas is smoothly discharged outside the machine. To discharge.

The gas that has reached the ozone deodorizing device 6 as described above is blown out by small air bubbles from the center and the side of the lower surface thereof by the air supply pipe 66, and the gas bubbles are substantially equally distributed on both sides of the air supply pipe 66. Since the residence time in water is extended while diffusing into water, and the ozone tube 68 uniformly sends out fine air bubbles from micropores of the entire circumference of the tube, the residence time of ozone gas in water is lengthened to increase the gas residence time. It is possible to perform aerobic action over a long period of time evenly over the entire air bubbles, efficiently decompose odor components in the gas with ozone gas, and remove dust mixed in the gas well in water by aeration action. Can be removed.

Further, the ozone deodorizing device 6 has a discharge processing path 6b which is formed by displacing the partition plate 69 up and down in the space above the water surface and is bent. Can be accurately suppressed by the partition plate 69, and by preventing the intrusion of moisture into the discharge processing path 6b, the two gases are detoured over time in the discharge processing path 6b, so that the Decomposition of the remaining odor components is promoted, and ozone can be eliminated. Therefore, there is an advantage that the deodorizing load in the photocatalyst deodorizing device 7 performed at the next level can be reduced, the deodorizing treatment capacity can be improved, and the size of the device can be reduced.

Next, the gas supplied from the ozone deodorizing device 6 is supplied to the photocatalyst deodorizing device 7 in the deodorizing chamber 7a from the side of the cover plate 71 and the side of the container 70 to have a gas-permeable catalyst curtain 75.
Are provided in a plurality of rows to form an exhaust path 7b which is bent in a plurality of stages, and a lamp 76 for irradiating ultraviolet rays is connected to the deodorizing chamber 7.
a, the lamp 76
Each catalyst curtain 75 is efficiently receiving the light irradiated by the air, and the photocatalytic action is activated.
When the gas sent from the air passage 7b passes through the exhaust path 7b, the gas is sufficiently contacted with the photocatalyst while bypassing each catalyst curtain 75,
Further, the gas can pass through the gaps 7e and between the glass fibers themselves due to the gas permeability of the catalyst curtain 75.
Since the exhaust resistance of the gas can be reduced as much as possible, the exhaust can be performed smoothly, and the direct contact of the gas with the photocatalyst can be satisfactorily performed. The gas from which the decomposition due to the photocatalytic action is promoted to remove the odor component can be satisfactorily discharged outside the apparatus.

At this time, the photocatalyst deodorizing device 7 is provided with the ozone deodorizing device 6 on the upper side in the exhaust direction, and is configured to perform the primary deodorizing and then the secondary deodorizing. The gas sent in a state in which the odor component is reduced and removed can prevent the catalyst curtain 75 from being contaminated or clogged with dust, and can increase the exhaust speed because the gas processing capability is improved. There is an advantage that the size of the device can be easily reduced.

According to the present invention, the following effects can be obtained by using the above-described organic waste treatment apparatus. When the water content is adjusted while stirring the processed material made of organic waste in the processing chamber, the mineral water containing the accelerator made of minerals that promotes the decomposition action of the processed material is supplied by the water supply device. Thereby, the supply of the water and the supply of the promoter can be easily performed at the same time, so that the suitable environment for the microbial bacteria in the processing chamber can be easily maintained, and the decomposition of the processed material by the microbial activity can be performed favorably. be able to. In this case, if the accelerator is a biological mineral extracted from a living organism, a suitable environment for microorganisms can be more suitably created, and the decomposition treatment of the treated product can be performed efficiently.

Further, the processing chamber supplies hot air heated by a hot air supply mechanism from one side thereof, and gas generated during processing is quickly discharged by a deodorizing exhaust mechanism without stagnation. A favorable environment is always maintained well, which promotes microbial activity and efficiently decomposes the processed material.Forcibly exhausted gas removes odor components in the gas during the discharge process and Since discharge can be performed smoothly, it is possible to provide a processing apparatus that can improve the decomposition processing efficiency of a processed product while reducing the size and prevent the discharge of odorous gas.

The hot air supply mechanism blows out hot air in the form of an air curtain from an air supply nozzle hole formed in a slit shape, so that the hot air can be blown from above the processing chamber onto a processing object or the like to be stirred. Thus, the evaporation of water can be carried out quickly, and an environment suitable for microorganisms can be created. In addition, by blowing hot air in the form of an air curtain between the two agitating bodies rotating opposite to each other in the processing chamber, it is possible to uniformly supply hot air to the agitated and loosened processed material, etc. It can provide an aerobic environment and facilitate the decomposition process.

Then, the gas discharged from the processing chamber is deodorized by performing aeration in ozone gas and water by an ozone deodorizer on the well side in the exhaust direction and then deodorizing by the photocatalytic action of the photocatalytic deodorizer. The gas after the primary deodorization while accurately removing dust in the gas by the aeration function can be satisfactorily removed by the secondary deodorization by the photocatalysis while reducing the processing load of the photocatalyst.
