DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively small, convenient, and sanitary system for kitchen waste, garbage generated in kitchens and kitchens of general households, and other wastes containing a relatively large amount of water, so-called garbage. The present invention relates to a processing device that can be used in a general manner.

[0002]

2. Description of the Related Art Typical waste generated from households is garbage, and most of the waste is generated around kitchens as kitchen waste. As for these waste treatments, it is a general method that a collection vehicle goes to a place for a predetermined time, collects them, and performs centralized treatment in a treatment facility such as an incineration plant.
Therefore, in general households and the like, it is necessary to store the waste until a predetermined time when the collection is performed, and it is necessary to transport the waste to a predetermined place where the collection is performed. In order to eliminate such inconveniences, some apparatuses and methods for treating waste at (near) a place where the waste is generated have been proposed. For example, a method of disintegrating garbage by mechanical force called a disposer and flowing it to the sewage with water,
There are a heating (partial combustion) type using a heater, microwaves, etc., a refrigeration type for eliminating odor, and a decomposition type using microorganisms. Under these circumstances, a drying method has recently been proposed. For example, Japanese Patent Application No. 3-346018 and Japanese Patent Application No. 5-84543. These wastes are heated and dried by heating means such as a heater, and the discharged steam is forcibly air-cooled by a condenser provided on the outside etc. to condense most of it, and the remaining exhaust components are exhausted through a deodorizer. Has a function of realizing a substantially odorless drying process. This type of garbage drying processor is characterized by condensing the generated steam and discharging it as drain water.At this time, since most of the odor components generated during heating can be dissolved and removed in the drain water, a deodorizer is required. There is an advantage that a small and simple configuration can be achieved.

[0003]

It is necessary to keep garbage in the vicinity of the place where the garbage is to be collected until a predetermined time when the garbage is collected. Since the garbage contains a large amount of water, the garbage itself forms an environment in which rot easily occurs. Therefore, the garbage is spoiled during storage, resulting in odor. In addition, heavy water increases the weight, and transporting the packed bag to a predetermined place where collection is performed has been heavy labor. In addition, moisture often leaks from bags containing kitchen waste during transportation to the collection site, and traces often cause new (secondary) odors. It was a compelling one. On the other hand, if we look at conventional kitchen waste treatment equipment, the disposer can grind the kitchen waste finely, but the wastewater after treatment contains a large amount of solids and organic components, which is one of the causes of organic pollution such as rivers. It was something. The incineration method has problems such as generation of odor during incineration and difficult ash treatment. In addition, the freezing type cannot reduce the weight of kitchen waste in principle. Among them, the drying method solves various problems related to the moisture contained in garbage, can also achieve reduction of garbage at the same time, and can be an easy-to-use device without generation of odor during treatment.

However, in the above-mentioned drying method,
The odor component is dissolved in the condensed water separated from the garbage, and the condensed water is stored in equipment such as the condensing part or the drain tank. I sometimes felt a strong odor. Ma
In the case of dry drying, the odor components generated during drying
Often, a deodorizer is installed so that it is not discharged to the drain. This
At that time, the odor component passed through the deodorizer is treated and almost odorless
At the same time, steam generated during drying is discharged outside the machine
Will be done. If this is done indoors, especially in winter
When the outdoor temperature is low, such as when
Condensation will form on the wall surface, window glass surface, etc.
If used for a long time, use window frames, wall surfaces, furniture, etc.
May cause mold, stains, corrosion, etc.
Was.

[0005] An object of the present invention is to solve the problems of the conventional dry garbage disposer.

[0006]

And a heating space between the heating means and the garbage container, and a stirring means for stirring the garbage are provided in the garbage container, and a deodorizer is provided in an exhaust path communicating from the heating space to the outside of the machine. , A condenser and a blower are sequentially arranged to form a garbage disposal machine.

Further, the garbage container and the heat insulating container are arranged substantially concentrically inside and outside, and a heating means for heating the garbage is provided above the garbage container to provide a space between the heating means and the garbage container. As a heating space, a stirring means for stirring the garbage is provided in the garbage container, and a deodorizer, a condenser, and a blower are sequentially arranged in an exhaust path communicating from the heating space to the outside of the garbage, and from the heating space. The garbage disposer is configured such that heat can be exchanged between a passage leading to the deodorizer and a passage leading from the deodorizer to the condenser.

Further, the garbage container, the heat-insulating container, and the condensing container are arranged substantially concentrically in this order from the inside, and a heating means for heating the garbage is provided above the garbage container. Between the garbage container and the condensing container as a condensing space, the heating space and the condensing space are separated by a sealing material provided above the condensing space, and the heating space and the condensing space are separated.

[0009]

The main component of garbage is water, which usually accounts for 70 to 80% of its weight. According to the present invention, the garbage is heated to separate water by evaporation, the garbage is processed into a dried product, and the steam is discarded as condensed water. At this time, if most of the odor components generated during heating are condensed with water vapor or dissolved in the condensed water, the condensed water itself becomes a source of odor. Therefore, it is important to prevent odor components from being contained in the condensed water. If condensed water containing odorous components is present in the condensing section or in the drainage container (inside the device), particularly highly volatile components are released outside the device when the device lid is opened, and this occurs when the lid is opened. May cause odor.

The present invention has been made in view of this point, and eliminates the re-evaporation of the odor component from the condensed water to prevent the odor from being emitted outside the machine. Specifically, an odor component generated together with a large amount of water vapor during heating and drying is passed through a deodorizer before being condensed, and only the odor component is oxidized and decomposed to be converted into an odorless substance. For that purpose, the flow path configuration is as follows: heating space, deodorizer, condensation vessel, (for suction) blower,
Since the odor component is deodorized before condensation of the steam, the condensed water does not contain the odor component and becomes odorless. Therefore, even if the condensed water remains in the device, it does not cause odor, and it is possible to flow out of the device as drain water as it is. Therefore, the odor generated during drying
Steam and water will be completely processed inside the processing machine.
The cause of the odor is cut off, and the steam
Can also solve the long-term problems associated with the emission of

FIG. 1 is a longitudinal sectional view of a main part of a first embodiment according to the present invention. 1 is a garbage container, 2 is a heat insulating container provided outside the garbage container 1, and is made of a composite material of metal and heat-resistant foamed plastic. 8 is a garbage container 1
A heater 9 for heating the garbage stored therein is a stirring fan, and both constitute a heating means, which are housed in a lid 7 which opens and closes when the garbage is taken in and out. 19 is a lid packing material. The hot air generated by the heating means is blown into the heating space 4 through the blowing holes 10 and circulates in the garbage container 1. The blowing temperature is 10
It is controlled at 0 to 130 ° C. The garbage container 1 is made of a heat-resistant plastic material, but a metal material or the like can also be used. 3 is a condensing container for condensing water vapor generated from garbage, 5 is a condensing space, and 16 is a cooling fan. Reference numeral 6 denotes a stirring blade for stirring and pulverizing garbage. The shaft 6a for rotating the stirring blade 6 penetrates the garbage container 1 and the heat insulating container 2. However, the shaft 6a is vertically divided at the penetrating portion of the garbage container 1, and the upper part and the stirring blade 6 are formed. By attaching to the garbage container and detachably connecting to the lower part of the shaft, the garbage container can be freely removed from the device. Thereby, usability as a device is improved. Reference numeral 11 denotes a water vapor exhaust port provided at an upper portion of the heat insulating container 2 and communicates with the deodorizer 12 via the deodorizer upstream passage 20. The deodorizer 12 includes a catalyst 13 and a catalyst heater 14 for heating and activating the catalyst 13, and the odor component is deodorized by a catalytic oxidation reaction.
As the catalyst, a catalyst in which a platinum-based noble metal was supported on a honeycomb-shaped ceramic support was used. The catalyst temperature was set to about 400 ° C. in order to smoothly carry out the oxidative decomposition reaction. The condensation container 3 is connected to the downstream side of the deodorizer 12 via a deodorizer downstream passage 21. Reference numeral 18 denotes a drainage tank for storing condensed water, and 17 denotes an inlet of the drainage tank. The drainage tank 18 is configured to be detachable from equipment to discard the collected condensed water. An exhaust pipe 22 was provided from the condensing container 3, and a blower for exhaust was provided ahead of the exhaust pipe 22. Here, a catalytic deodorizer utilizing an oxidative decomposition reaction is used as the deodorizer, but other methods can also be used. For example, there is an oxidative decomposition method using ozone.

Next, the operation of the garbage drying process will be described. First, the lid 7 is opened and garbage is put into the garbage container 1. Next, the lid 7 is closed to complete the preparation, and the process proceeds to the heating operation. The heater 8 and the stirring fan 9 are energized to start heating the garbage. At the same time or by monitoring the temperature of the garbage, the cooling fan 16, the exhaust blower 15, and the catalyst heater are also operated. The temperature of the garbage gradually rises and steam begins to evolve. To increase the heat insulation of the garbage container 1,
This is effective for efficiently generating steam (improving heating efficiency). The generated water vapor and odorous component gas exit from the water vapor exhaust port 11 and first pass through a deodorizer. At this time, the offensive odor component is oxidized and decomposed into an odorless component and sent to the condensation space 5 together with the water vapor. The water vapor flowing into the condensing space 5 is forcibly air-cooled by the cooling fan 16 and condensed there. The condensed water generated in the condensing space 5 flows out of the drain tank inlet 17 and is stored in the drain tank 18. If there is no drain tank 18 or the like, it will be discharged out of the machine. In this manner, drying of the garbage proceeds, and water is separated from the garbage.

A small amount of gaseous odor component generated together with the water vapor in the drying process passes through the deodorizing section 12 and is converted into an odorless component, and then moves to the condensation space 5 together with the water vapor, so that the odor component is dissolved in the condensed water. do not do. The remaining odorless gaseous components (air and the like) are sucked by the exhaust blower 15 through the exhaust pipe 22 and exhausted outside the machine. The end of the drying process is performed by detecting a temperature change of the condensing container 3 and the like (not shown). After the processing is completed, the dried refuse remains in the garbage container 1, and the condensed water is stored in the drainage tank 18. Further, during the operation of the blower 15, since the air inside the device is sucked, the inside of the device is always in a decompressed state during the process, and the generation of odor during the process can be prevented. In addition, as for the intake of air for the catalytic oxidation reaction, it is practically possible to take in air into the inside of the machine through the gap of each part by the operation of the blower, but it is also possible to install the air intake in the lid part or the like in advance. good.

FIG. 2 is a longitudinal sectional view of a main part of a second embodiment according to the present invention. 1 are denoted by the same reference numerals as those in FIG. 1, and description thereof will be omitted. This configuration is characterized in that the deodorizer upstream passage 30 and the deodorizer downstream passage 31 are heat exchangeable as a double tube. The temperature of the generated steam is in the range of 100 to 130 ° C. at the steam outlet 11, but about 400 ° C. to ensure the oxidation reaction by the catalyst in the deodorizing section 12.
It is necessary to raise the temperature. On the other hand, after passing through the deodorizer 12, it is necessary to cool to approximately room temperature in order to condense water vapor. Therefore, a configuration is adopted in which high-temperature heat at the outlet side of the deodorizer 12 is transmitted to the inlet side of the deodorizer 12 to assist heating in the deodorizing unit, and at the same time, the outlet side of the deodorizer 12 is cooled to reduce the cooling load in the condensation space 5. did. With this configuration, the heating amount for deodorization could be reduced to about 1/3 as compared with the embodiment shown in FIG.

FIG. 3 is a longitudinal sectional view of a main part of a third embodiment according to the present invention. 1 and 2 are denoted by the same reference numerals, and description thereof will be omitted. Here, the condensing container 43 is disposed outside the garbage container 1, and the heat insulating container 42 formed of a metal double wall is provided therebetween.
And the condensing container 43 to form a compact configuration.
It is effective to make the inside of the heat insulating container 42 a vacuum state, but the function can be exerted even in a state filled with air. The heating space 44 and the condensing space 45 are separated by a sealing material 40 so that water vapor or the like does not directly move between them. 56 is a cooling fan. The heating space 44 and the condensing space 45 are indirectly connected via a deodorizer 52.
The deodorizer is formed of a honeycomb catalyst 53 and a catalyst heater 54. The steam outlet 11 is formed immediately above the sealing material 40, and the heating space 44 communicates with the deodorizing section 52 through the deodorizing section upstream passage 49, and further through the deodorizing section downstream passage 50 and the condensing space inlet 48. And is communicated with the condensing space 45 in a bypass manner. 47 is a drain port provided at the lower part of the condensation container 43,
Reference numeral 51 denotes a drain pipe, 58 denotes a drain tank for storing condensed water, 57 denotes an inlet of the drain tank, 62 denotes an exhaust pipe branched from the drain pipe 51, and 55 denotes a blower for suction.
Also in the case of this embodiment, water vapor is condensed after passing through the deodorizer as in the first and second embodiments. That is, the steam and odor components generated from the heated garbage are first sent from the heating space 44 to the deodorizer 52 through the steam outlet 11. Here, the odor component is oxidized and decomposed into an odorless substance and moves to the condensation space 45. Here, the water is forcibly air-cooled by the cooling fan 56 to condense the steam. The condensed water is stored in a drain tank 58 through a drain pipe 51. Since the drainage tank is detachable, condensed water is discarded when a sufficient amount of condensed water is obtained in a plurality of processes. At this time, since the condensed water has no odor, it is also possible to provide a drain pipe instead of the drain tank 58 and discharge the condensed water outside the machine. Further, similarly to the configuration shown in the second embodiment, the heat input between the deodorizer upstream passage 49 and the deodorizer downstream passage 50 is configured to be heat exchangeable, so that the heating input for activating the catalyst can be significantly reduced. It becomes possible.

The present invention is particularly effective for a relatively small-sized dry garbage disposal machine suitable for household use, but can also be applied to a large-sized industrial garbage machine. In addition, it is mainly suitable for use as an independent device, and can be used both indoors and outdoors because there is no odor. In addition, it is also possible to use it by incorporating it in a system kitchen.In this case, since the generation of garbage is mainly around the kitchen sink, this device can be installed in the closest place to the generation place,
User operability and convenience are further improved.
