Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal method in which garbage discharged from a home or a restaurant is put into a processing container having a pulverizing mechanism, heated and dried to produce powdery reduced garbage. The present invention relates to an apparatus for improving the deodorization of odorous exhaust gas generated in the process of processing garbage.

[0002]

2. Description of the Related Art In recent years, reduction of garbage has been receiving a great deal of attention from the viewpoint of lack of garbage disposal sites.
Many devices for reducing the amount of garbage discharged from homes and restaurants have been developed and put on the market.

The garbage generated in kitchens of these stores and kitchens at home contains a large amount of water, and when discarded or left as it is, it rots and emits a noticeable odor, so that the garbage is dried by heating. In addition, there has been proposed a pulverizer which is pulverized and treated as a powdery dust having a very small odor and a small volume.

[0004]

However, in the above-mentioned garbage processing apparatus, although there is almost no odor or the like with respect to the powdered garbage after the processing, the garbage is dried during the processing of the garbage. The exhaust gas discharged from the processing container to the outside often has an odor, and the odorous exhaust gas contains a large amount of water in which garbage is present. However, even if an attempt is made to remove odors using activated carbon or a deodorizing filter, the deodorizing ability is immediately reduced and a good deodorizing state cannot be obtained. There has been a long-felt need for a method that can easily and satisfactorily deodorize odorous exhaust gas containing a large amount of water discharged from the inside of the processing container.

[0005] For this reason, the present inventors have previously disclosed in Japanese Patent Application No.
No. 215509, ozone generated by an ozone generator is aerated into water to form ozone water, and odorous exhaust containing a large amount of water in the ozone water is introduced and aerated to make it contact and deodorize. Although a garbage disposal device has been proposed, although it is possible to sufficiently deodorize this device, it is necessary to replenish or periodically exchange water for aerating the ozone and odorous exhaust. However, when the temperature of these aerated waters increases, the ozone solubility in the water may be reduced and sufficient deodorizing ability may not be obtained, so that the cooling for cooling the aeration tank for storing the aerated water is performed. Just as water is needed, water is required for its operation.However, when installing these garbage disposal devices, not only must new water conserving facilities be installed at the installation locations, but also There is a problem that management of it is troublesome.

Accordingly, the present invention has been made in view of the above-mentioned problems, and it is not necessary to newly provide a water-use facility when installing a garbage disposal apparatus, or to perform garbage disposal without the need to manage water or the like during its operation. It is intended to provide a processing device.

[0007]

In order to solve the above-mentioned problems, a garbage disposal apparatus according to the present invention comprises a heating means for heating garbage in a processing container by irradiation of at least a microwave of a predetermined frequency; A crushing means for cutting or pulverizing the heated garbage to powder, wherein the garbage in the processing container is heated and dried to be powdered. Exhaust cooling means for cooling the discharged odorous exhaust by heat exchange with the outside air, ozone generating means for generating ozone of a predetermined concentration, and ozone generated by the ozone generating means to the exhaust cooling means And ozone mixing means for introducing and mixing with the cooled odorous exhaust gas. According to this feature, the ozone generated by the ozone generation means is mixed with the odorous exhaust gas cooled at a low temperature by the exhaust cooling means for cooling by heat exchange with the outside air, whereby Since the life of ozone is properly maintained in the exhaust air and good deodorization (deodorization) processing is performed, water is not required for operation of the apparatus. There is no need to newly install or manage water during its operation.

In the garbage disposal apparatus of the present invention, the exhaust cooling means has a high-temperature cooling section for cooling the high-temperature exhaust gas from the processing vessel, and has a relatively low temperature cooled by the high-temperature cooling section. And a low-temperature cooling unit that cools the odor exhaust gas, and it is preferable that the high-temperature cooling unit be used as heating outside air for introducing outside air that has been subjected to cooling and raised in temperature into the processing container. . In this way, not only can the odorous exhaust be efficiently cooled, but also the heat efficiency of the device can be improved by reusing excess heat that is unnecessary in the odorous exhaust cooling process for heating the garbage. It is possible to carry out efficient garbage disposal.

In the garbage disposal apparatus of the present invention, it is preferable that the low-temperature cooling section, the ozone generation means and the ozone mixing means are separate from a main apparatus provided with other means. In this way, the separate device can be installed outdoors, like an outdoor unit, and can be cooled by outside air.

In the garbage disposal apparatus of the present invention, the ozone mixing means is capable of passing odorous exhaust gas cooled by the exhaust gas cooling means, and the ozone introduction section generated by the ozone generation means. Is preferably formed of a tubular body whose diameter is smaller than the diameter of the upstream and downstream portions of the introduction section. With this configuration, the flow rate of the odorous exhaust gas in the introduction section is increased, and the introduction of the ozone is performed satisfactorily, and the introduced ozone and the odorous exhaust gas have a large diameter downstream of the introduction section. Mixing contact is easy in the region.

In the garbage disposal apparatus of the present invention, it is preferable that a stirring blade for mixing odorous exhaust gas and ozone is provided at a downstream portion of the large-diameter ozone introduction section.
By doing so, the introduced ozone and the odorous exhaust gas are mixed well, and even with a small amount of ozone, good deodorization (deodorization) is achieved.
It can be performed.

Next, the main body 10 of the garbage disposal apparatus described above
A description will be given of the processing device 101 for odorous exhaust gas discharged from the odor exhaust device 101. The processing device 101 for odorous exhaust gas of the present embodiment (hereinafter, abbreviated as exhaust gas processing device) is, as shown in FIG. The housing 103 has a plurality of openings 10 on its side surface to allow outside air to be taken into the housing 103.
2 are drilled. The main body 10
The connection hose 105 is connected to the main body 100, and the odorous exhaust discharged from the main body 100 is introduced. The odorous exhaust introduced and deodorized is led out from the rear surface of the housing 103. The air is exhausted through the exhaust hose 104 through an exhaust duct or the like or directly to the outside air.

As described above, in the present embodiment, as described above, the main body 100 for drying and pulverizing garbage is separated from the exhaust processing apparatus 101 for removing odorous exhaust discharged from the main body. In this manner, as shown in FIG. 1, the exhaust treatment device 101 can be used by being disposed on the side of the main body 100, and as shown in FIG. It is configured so as to be easily performed.

The configuration of the exhaust treatment apparatus 101 of this embodiment is
Referring to the side cross-sectional view of FIG. 17, first, the exhaust treatment apparatus 101 mainly has a relatively low temperature in the heat exchanger 50 as a high-temperature cooling section introduced from the connection hose 105. A cooling unit including a radiator unit 106 as a low-temperature cooling unit for performing further cooling of the odor exhaust by air cooling, an ozone generating unit including an ozone generating unit 111 for generating ozone, and an odor cooled by the cooling unit It is mainly composed of a mixing processing section including a mixing unit 110 as ozone mixing means for mixing the exhaust gas with the ozone generated by the ozone generation unit 111 to remove odor from the odorous exhaust gas.

First, the radiator unit 106 used in the cooling section of this embodiment is substantially the same as the heat exchanger 50 used in the main body 100, and is formed as a fine pipe having a large surface area by using radiation fins or the like. A relatively cooling capacity that cools the inside of the pipe with the outside air blown by the blower wings 109 that are supported by the drive motor 108 held on the protective frame 107 and that allow the outside of the fine pipe to pass through the odorous exhaust gas. It is considered to be a big thing, and by cooling odorous exhaust with air cooling,
The device does not require cooling water or the like.

The ozone generation unit 111 used in this embodiment is capable of continuously generating ozone by high-voltage discharge, and includes a transformer 112 and a transformer 112 for generating these high voltages. Along with a pneumatic pump 113 for supplying outside air to the ozone generation unit 111, as shown in FIG.

The air containing ozone generated by the ozone generation unit 111 and the radiator unit 10
The odor-exhausted air cooled at 6 is mixed with the mixing unit 1 formed into a tubular shape through the introduction pipe 115 and the communication pipe 114.
The mixture is guided to 10 and mixed to perform deodorization.

The mixing unit 11 used in this embodiment
As shown in FIG. 18, the configuration of No. 0 is a tubular body having, at both ends, an inlet 120 for the odorous exhaust and an outlet 124 from which the mixed and treated exhaust is discharged.
At the downstream position of the inlet 120, the introduction pipe 11
Ozone inlet 12 to which air containing ozone generated by the ozone generating unit 111 is introduced.
1 is provided, and the tube diameter of the ozone introduction part 122 in which the ozone introduction port 121 is formed is smaller than the other parts.

As described above, reducing the diameter of the tube of the ozone introduction section 122 reduces the flow rate of the odorous exhaust gas from the ozone introduction section 122 so that the ozone-containing air can be smoothly introduced. At the same time, by increasing the pipe diameter of the downstream mixing section as in the mixing section 123 of the present embodiment, the mixing of ozone and odorous exhaust is promoted due to the generation of turbulence due to the decrease in flow velocity. However, the present invention is not limited to this.

As shown in FIG. 18, the mixing unit 110 of this embodiment has a rotatable mixing device for mixing ozone and odorous exhaust gas at an upstream position of the mixing unit 123. The propeller 125 is provided, and it is preferable that such a process is performed, because by promoting the mixing, it is possible to perform a favorable treatment of the odorous exhaust gas with a small amount of ozone, but the present invention is not limited to this. Absent.

Next, the main body 100, which is the garbage processing apparatus of the present embodiment configured as described above, and the exhaust processing apparatus 1
01 will be described.

When garbage is put into the processing container 1, the microwave shielding upper cover 4 and the safety upper cover 5 are closed, and then the selection switch of the power switch on the operation panel 6 is turned on, the pair of microwave oscillators 10 operates. Then, the microwave is radiated into the processing vessel 1 from the facing microwave irradiation port 9, and the stirring blade 45 periodically repeats forward rotation and reverse rotation along the bottom surface of the processing vessel 1. Accordingly, the scraper 49 rotates along the inner peripheral surface of the processing container 1. Further, the rotary cutter 46 rotates at a high speed in a predetermined direction slightly above the stirring blade 45, and further, the warm air is blown from the left and right lower warm air blowing ports 12 a and the left and right upper warm air blowing ports 12 b, and from the exhaust port 13. It is sucked and exhausted. Also, the bottom wall 1 of the processing vessel 1
The drain falls from the discharge port 15 of the fourth through the water hole of the water plate 32. FIG. 9 shows that microwave irradiation, hot air blowing, suction and exhaust, and drain discharge are performed simultaneously.

Since the microwave irradiation port 9 is provided at the lower part of the processing container 1, the garbage introduced into the processing container 1 does not always form a space between the microwave irradiation port 9 and the garbage. The microwave is directly irradiated from the vicinity of the microwave irradiation port 9, and the irradiated microwave is immediately absorbed by the water of the garbage which has been stirred and shredded by the stirring blade 45. Further, the microwave irradiation port 9 is connected to the microwave transmitting plate 1.
The attachment of dust to the surface 1 is prevented by the scraper 49.
Therefore, the efficiency of using microwave energy is high, the drying process of the dust can be efficiently performed, and the ignition of the dust due to excessive heating can be avoided.

The two blades 45a and 45b of the stirring blade 45
Is inclined upward from one side edge 45d toward the other side edge 45f, so that when the stirring blade 45 with the one side edge 45d facing forward rotates forward, the garbage is removed from the processing container 1. Is scraped up by the two blades 45a and 45b at the bottom portion, and is chopped by the rotary cutter 46 when the blades are scraped up. The stirring blade 45 repeats the normal rotation and the reverse rotation every set time by the operation of the timer, and the other side edge 45 having the vertical surface is rotated.
When f is turned backward, the garbage is greatly stirred so as to be turned upside down. With the forward / reverse rotation of the stirring blade 45, the pair of scrapers 49 also rotate forward / reverse along the inner peripheral surface of the side wall 8 of the processing container 1, so that the attached scraper 49 adheres to the inner peripheral surface of the side wall 8 of the processing container 1. Kimono is immediately scraped. The rotating cutter 46 intermittently rotates in the same direction at a set time interval intermittently by a timer operation.

The hot air from the lower hot air blowing port 12a is blown directly from the side onto the garbage that has been agitated by the stirring blades 45 and shredded by the rotary cutter 46, and is blown into the left and right upper hot air. Since the warm air from the mouth 12b is blown downward from above toward the garbage, the heating by the microwave and the convection action are added to the heating by the microwave, and the drying of the garbage is promoted. Odorous exhaust containing water vapor and gas evaporated from the garbage is sucked and exhausted from the exhaust port 13, filtered by the dust collecting bag 28 in the dust absorbing pox 25, and cooled by heat exchange in the heat exchanger 50. The connection hose 105
Is sent to the exhaust treatment device 101 via the. At this time, the odorous condensed water generated by cooling by heat exchange is collected in the drain collection container 34 together with the wastewater discharged from the garbage.

The relatively low-temperature odorous exhaust sent to the exhaust treatment device 101 is supplied to the radiator unit 1.
After further cooling at 06, contact with ozone is measured at the mixing unit 110, odorous components are decomposed by the oxidizing ability of the ozone, deodorization is performed, and the exhaust hose 104 is exhausted.
The air is exhausted through the exhaust duct and the outside air.

In this embodiment, a humidity sensor (not shown) is provided immediately outside the exhaust port 13 or from there to the dust-absorbing pox 25, and detects the humidity in the exhaust air to control the operation panel 6. The circuit inside is controlled. For example, when the humidity falls to the set value, the end of the drying process is notified, or when the humidity falls within a certain range, the blowing of the hot air is interrupted, and when the humidity reaches the upper limit, the blowing of the hot air is restarted. Control is conceivable.

In order to discharge the dried refuse having been subjected to the above-described drying process from the processing container 1, the switching motor 36 is operated and the exhaust tray 23 is placed directly below the discharge port 15 as shown in FIGS. Position. The dried dust in the processing container 1 is sucked into the exhaust tray 23 corresponding to the discharge port 15 and collected in the dust collecting bag 28 through the suction hose 24, so that the subsequent processing is easy.

In the garbage processing apparatus of this embodiment, the radiator unit 10 of the exhaust processing apparatus 101 is used.
6 shows a comparison test of the deodorization status between the case where the odorous exhaust gas was passed and the case where the odor exhaust was not passed, and the comparison test of the deodorization status between the case where the mixing propeller 125 was provided in the mixing unit 110 and the case where the mixing propeller 125 was not provided The results are shown in FIG.

As shown in the results of FIG. 20, when the odorous exhaust gas is cooled by using the radiator unit 106 as the low-temperature cooling unit, the temperature of the odorous exhaust gas flowing into the mixing unit 110 is about 45 degrees. (Outside air temperature is 22 degrees C.), and the odor of the processing exhaust gas discharged from the mixing unit 110 was almost removed, while the odor from the mixing unit 1 was not passed through the radiator unit 106.
The temperature of the odorous exhaust gas flowing into 10 was as high as 58 degrees, and the odor remained in the process exhaust gas discharged from the mixing unit 110.

The reason why the deodorizing ability is improved by lowering the exhaust gas temperature is that the rate of decomposition of ozone is reduced by cooling, and the ozone is decomposed before the ozone acts on the odorous component, resulting in good deodorization. It is considered that (deodorization) can be avoided.

Also, based on the results of a comparison test of the deodorizing conditions of the case where the mixing propeller 125 is provided and the case where the mixing propeller 125 is not provided, active ozone is introduced so that the ozone introduced into the mixing unit 110 is brought into contact with the odor component quickly. It is preferable to perform mixing, and in this case, good deodorization is performed even in the initial stage of the treatment in which a large amount of odor components are contained in the exhaust gas, which is necessary for performing such good deodorization (deodorization). It can be understood that the ozone concentration can be reduced, that is, the ozone generation unit 111 can be used even if it is less expensive and can generate only low-concentration ozone.

For example, in the above-described embodiment, the ozone generating unit 111 generates ozone by discharging. However, the present invention is not limited to this. For example, an ultraviolet lamp or the like may be used.

In the above-described embodiment, the exhaust treatment device 10
Although 1 is separate from the main body 100, the present invention is not limited to this, and it goes without saying that these may be integrated.
