Description

  The present invention relates to a garbage drying processing apparatus for drying, reducing and reducing the volume of garbage generated mainly at home.

  Conventionally, this kind of garbage drying processing apparatus is reducing and reducing the volume of garbage (for example, refer patent document 1). FIG. 3 shows a conventional garbage drying processing apparatus described in Patent Document 1. In FIG.

  This garbage drying processing apparatus includes a garbage processing unit 2 including a stirring device 1 that dries crushed garbage, a condensing unit 4 that is air-cooled by cooling air blowing means 3, and water condensed in the condensing unit 4. The drainage pipe 5 for draining, the garbage processing unit 2, the condensing unit 4, the air blowing unit 6, the heating unit 7 for heating the air from the condensing unit 4, and the catalyst deodorizing unit 8 for deodorizing the air by the catalyst are communicated in a circulating manner. The air circulation passage 9 is made up of.

First, when garbage is input into the garbage processing unit 2, the air blowing means 6 forms an air flow that circulates between the garbage processing unit 2 and the condensing unit 4 via the air circulation passage 9. The air heated by the heating means 7 and deodorized by the catalyst deodorizing unit 8 is heated (for example, 130 to 150 ° C.) and then flows into the garbage processing unit 2 to quickly dry the garbage. Subsequently, the air containing the steam generated in the garbage processing unit 2 is drawn into the condensing unit 4 through the air circulation passage 9A on the outflow side, and condensed in the condensing unit 4 that is air-cooled by the cooling air blowing means 3. Then, the condensed water is drained from the drain pipe 5. Next, the air flows into the inflow side air circulation passage 9B, and the air circulates.
JP-A-5-96271

  However, in the above-described conventional configuration, the air cooling by the cooling air blowing means 3 using the outside air has a small temperature drop on the inner surface of the condensing unit 4 and naturally the air temperature drop is also small. As a result, since the saturated vapor pressure of air cannot be lowered sufficiently, there is a problem that the condensing capacity of the condensing unit 4 is low.

  That is, when the steam generated in a large amount in the garbage processing unit 2 cannot be condensed in the condensing unit 4, the steam that could not be condensed returns to the garbage processing unit 2 again, so that it takes a very long time to dry the garbage. However, it was difficult to put into practical use.

  Further, since the odor component is contained in the steam generated from the garbage, the catalyst deodorizing unit 8 is indispensable. In order to activate the catalyst of the catalyst deodorizing unit 8 (for example, platinum palladium), the catalyst is heated by the heating means 7. It is necessary to set it to 400 ° C or higher. As a side effect, a heat insulating configuration (not shown) is required. That is, the heating means 7, the catalyst deodorization part 8, and the heat insulation structure had the subject that cost became a factor.

  In addition, it is inevitable that the air heated by the heating means 7 and raised in temperature has a problem that when the garbage is dried, the garbage is thermally decomposed to generate a large amount of odor components. .

  In other words, the catalyst deodorizing unit 8 exhibiting the deodorizing performance has a vicious cycle in which the odor component increases.

  Moreover, although condensed water, such as trimethylamine, which is an odor component dissolves in the condensing unit 4, the amount of the condensed water is small, which is insufficient to remove the odor component. Moreover, since garbage and sulfur are contained in garbage, the condensed water in the condensation part 4 is acidic, and had the subject of corroding the condensation part 4 and the drain pipe 5.

  This invention solves the said subject, and it aims at providing the garbage drying processing apparatus which aimed at the condensation capability improvement of the condensation part, and simplification of an apparatus.

  In order to solve the above-described conventional problems, a garbage processing unit that includes heating means to dry garbage, a condensing unit that condenses steam generated in the garbage processing unit with stored liquid, and a condensing unit A water supply pipe for supplying the liquid, a drain pipe for discharging the liquid communicated and stored in the condensing unit, a ventilation circulation passage for circulating the garbage processing unit, the condensing unit and the blowing means in a circulating manner; Both the outlet side passage from the garbage processing unit and the inflow side passage to the garbage processing unit in the air circulation passage face the upper space of the condensing unit, and the condensing unit and the garbage It was set as the structure which heat-exchanges with the air in a process part.

  Alternatively, the passage on the outflow side from the garbage processing section in the blower circulation passage faces below the liquid level of the liquid stored in the condensing section, and the passage on the inflow side to the garbage treatment section in the blower circulation path Is exposed to the upper space of the condensing unit, and heat is exchanged between the condensing unit and the air in the garbage disposal unit.

  Thereby, a ventilation means forms the flow of the air which circulates through a garbage processing part and a condensation part via a ventilation circulation path. And the heating means provided in the ventilation circulation passage heats the air, and the air whose temperature has risen is ejected to the garbage processing section to dry the garbage. Subsequently, the air containing the vapor is ejected to the condensing part, directly collides with the stored liquid, and then flows along the stored liquid surface. At that time, the stored liquid is cooled with water and the temperature of the air rapidly decreases, and the vapor in the air condenses. On the other hand, the air containing the steam flows into the condensing part and passes through the liquid stored in the condensing part as bubbles, so that the temperature of the air is drastically decreased due to water cooling with the stored liquid. Condenses in large quantities.

  The garbage drying treatment apparatus of the present invention is a water-cooled device in which air containing steam generated from garbage is not air-cooled by outside air but directly collided with the liquid stored in the condensing part, and has a higher thermal conductivity than air. Water cooling has the effect that the condensation capacity of the condensing part is high, a large amount of garbage can be dried in a short time, and the condensing part can be made compact. Further, since the odor component contained in the steam generated from the garbage is dissolved in the condensed water or the stored liquid, the odor can be suppressed, and there is an effect that it is not necessary to provide a conventional catalyst deodorization part.

  1st invention is provided with a heating means, a garbage processing part which dries garbage, a condensing part which condenses the vapor generated in the garbage processing part with a stored liquid, and the liquid communicated with the condensing part A water supply pipe for supplying water, a drain pipe for discharging the liquid stored in communication with the condensing unit, and a ventilation circulation passage in which the garbage processing unit, the condensing unit and the blowing means communicate in a circulating manner, Both the passage on the outflow side from the garbage processing unit and the passage on the inflow side to the garbage processing unit in the air circulation passage face the upper space of the condensing unit, and the air in the condensing unit and the garbage processing unit And are configured to exchange heat.

  When garbage is thrown into the garbage processing unit, the blowing means forms an air flow that circulates between the garbage processing unit and the condensing unit through the ventilation circulation passage. Then, the heating means provided in the inflow side air circulation passage heats the air, and the air whose temperature has risen and the relative humidity has dropped is jetted from the outlet of the inflow side air circulation passage to the garbage processing section to dry the garbage. To do. Subsequently, the air containing the steam generated from the garbage is ejected from the outlet of the blast circulation passage on the outflow side to the condensing unit, directly collides with the liquid stored in the condensing unit, and then flows along the stored liquid surface. . At that time, the stored liquid is directly cooled with water, and the temperature of the air rapidly decreases, the saturated vapor pressure of the air decreases and the vapor in the air condenses.

  The condensed water is mixed with the stored liquid directly or after adhering to the inner surface of the condensing part. That is, air is not directly air-cooled by outside air, but directly water-cooled with a liquid having high thermal conductivity, so that there is an effect that the condensing part has high condensing capacity. Specifically, even when a large amount of garbage is thrown into the garbage processing unit and a large amount of steam is generated in the garbage processing unit, a large amount of steam is condensed in the condensing unit, so that a large amount of garbage is reduced in a short time. Can be dried.

  Further, after condensation, air (saturated vapor pressure) flows into the inlet of the ventilation circulation passage on the inflow side to the garbage processing unit, and air circulation is formed. On the other hand, the odor component (for example, trimethylamine which is the smell of rotten fish) contained in the steam generated from the garbage is dissolved in the condensed water or the stored liquid, so that the odor is suppressed. Moreover, since the condensed water acidified with sulfur or nitrogen derived from garbage is diluted from a large amount of stored liquid compared to this condensed water, there is no problem.

  2nd invention is provided with a heating means to dry a garbage processing part, a condensing part which condenses the vapor generated in the garbage processing part with a stored liquid, and the liquid communicating with the condensing part A water supply pipe for supplying water, a drain pipe for discharging the liquid stored in communication with the condensing unit, and a ventilation circulation passage in which the garbage processing unit, the condensing unit and the blowing means communicate in a circulating manner, The passage on the outflow side from the garbage processing section in the blower circulation passage faces below the liquid level of the liquid stored in the condensing section, and the passage on the inflow side to the garbage treatment section in the blower circulation path is condensed. The heat exchanger exchanges heat between the condensing part and the air in the garbage disposal part.

  The air containing the steam is ejected from the outlet of the air circulation passage on the outflow side to the condensing part and passes through the liquid stored in the condensing part as bubbles, so that the contact area between the liquid stored in the condensing part and the air is large. Become very wide. As a result, the air is sufficiently cooled with the liquid stored in the condensing unit, the temperature of the air rapidly decreases, the saturated vapor pressure of the air decreases, and a large amount of vapor in the air condenses. The condensed water is mixed with the stored liquid directly or after passing through the stored liquid and adhering to the inner surface of the condensing unit. In other words, since the air passes through the liquid in the form of bubbles, there is an effect that the condensing capacity of the condensing part is very high. In other words, the condensing part can be made more compact because the condensing part has a higher condensing capacity. Moreover, since the condensed water acidified by sulfur or nitrogen derived from garbage is diluted from a large amount of stored liquid compared to this condensed water, there is no particular problem. In addition, the odor component contained in the steam generated from garbage is sufficiently dissolved in the stored liquid because the contact area between the stored liquid and air (the surface area of the bubbles) is very wide, so the odor is reliably suppressed. It is done.

  According to the third aspect of the invention, in particular, the arrangement of the heating means of the first aspect of the invention or the second aspect of the invention is such that at least one of the passageway on the inflow side to the garbage treatment unit in the air circulation passage and the outer surface of the garbage treatment unit. With this configuration, the heating means provided in the air circulation passage on the inflow side heats the air, and the temperature rises so that the relative humidity decreases and the dried air is blown out to the garbage processing section to dry the garbage. In addition, the heating means provided on the outer surface of the garbage processing section can directly heat the garbage through the garbage processing section, and can efficiently generate steam from the garbage processing section. It is possible to prevent the condensed water from adhering to the inner surface.

  According to a fourth aspect of the invention, in particular, the condensing unit according to any one of the first to third aspects includes a water level detection unit that detects a water level of the stored liquid, and an output of the water level detection unit exceeds a predetermined value. In this case, after the stored liquid is drained from the drain pipe, the liquid is accumulated again from the water supply pipe, so that the upper space of the condensing part becomes narrow, and particularly when the water is full, the air flow is delayed due to the blockage of the air circulation passage. Can be prevented. In addition, since the liquid stored in the condensing part is replaced when the water level of the stored liquid becomes high, the temperature and odor component concentration of the stored liquid are controlled within a certain range, the condensing capacity of the condensing part is stabilized, and odor is also suppressed. It is done. Furthermore, when the liquid stored in the drain pipe is drained, the air containing the steam generated from the garbage is drawn into the drain pipe by the drained liquid, and the air flows from the outlet of the outlet circulation passage to the condensing part. Since it is ejected and discharged as bubbles together with the liquid, it is possible to exhaust odor components that are difficult to dissolve in the liquid (for example, methyl mercaptan, which is the smell of rotten onions), and the conventional catalyst deodorizing unit is unnecessary. As a result, it is not necessary to heat the catalyst to 400 ° C. or higher, the heating means may have a small capacity, and the heat insulation may have a simple configuration, so that the cost can be reduced. In addition, since air does not become hotter than necessary, it is possible to prevent a large amount of odorous components from being generated due to high-temperature pyrolysis of garbage.

  In the fifth aspect of the invention, in particular, the water level detection unit of the fourth invention is configured to detect the water level of the liquid stored in the condensing unit by stopping the air blowing means, so that the liquid level of the liquid stored in the condensing unit Is stabilized, so that the detection accuracy of the water level detector is improved.

  In the sixth aspect of the invention, in particular, when the water level detection unit of the fifth aspect of the invention does not output the increase of the water level for a predetermined period, the blower means and the heating means are stopped, so that the garbage in the garbage processing container is disposed. Can be judged to have been sufficiently dried, and energy can be saved.

  In the seventh invention, in particular, the condensing unit of any one of the first to third inventions includes a condensing temperature detecting unit that detects the temperature of the stored liquid, and the output of the condensing temperature detecting unit has a predetermined value. When it exceeds, it is possible to prevent the condensing part from deteriorating in condensing capacity by draining the stored liquid from the drain pipe and then collecting the liquid again from the water supply pipe. In addition, since the liquid stored in the condensing unit is replaced when the temperature of the stored liquid becomes high, the water level and odor component concentration of the liquid stored in the condensing unit are controlled within a certain range, and the air flow is prevented from stagnation. The odor is also suppressed. Furthermore, when the liquid stored in the drain pipe is drained, the air containing the steam generated from the garbage is drawn into the drain pipe by the drained liquid, and the air flows from the outlet of the outlet circulation passage to the condensing part. Since it is ejected and discharged in the form of bubbles together with the liquid, it is possible to exhaust an odor component (for example, methyl mercaptan) that is difficult to dissolve in the liquid, and the conventional catalyst deodorizing unit is not required. As a result, it is not necessary to heat the catalyst to 400 ° C. or higher, the heating means may have a small capacity, and the heat insulation may have a simple configuration, so that the cost can be reduced. In addition, since air does not become hotter than necessary, it is possible to prevent a large amount of odorous components from being generated due to high-temperature pyrolysis of garbage.

  In an eighth aspect of the present invention, in particular, an open air intake means having an open / close valve for taking in outside air is provided in the garbage processing section of the fourth or seventh aspect of the invention, and the open / close valve is used when draining the stored liquid from the drain pipe. Since the outside air is taken in from the outside air intake means when the stored liquid is drained from the drain pipe, the garbage processing unit can be prevented from becoming negative pressure, and the liquid can be smoothly mixed with the air. Can be drained. As a result, the odor component that is difficult to dissolve in the liquid can be exhausted sufficiently.

  In a ninth aspect of the invention, in particular, the garbage processing section of any one of the first to third inventions is provided with a stirring means for stirring the garbage, and the blowing means is stopped during the drive period of the stirring means. By comprising, it can prevent that the garbage scattered by the drive stirring means is carried by the circulating air, and is discharged | emitted accidentally from a garbage processing part. As a result, garbage does not adhere to the condensing unit, the blowing unit, and the heating unit.

  Reference numeral 25 denotes a garbage processing unit including a stirring unit 26, which dries the crushed garbage separated by the solid-liquid separator 23. A geared motor 27 drives the stirring means 26. 28 is a condensing part for condensing steam generated in the garbage processing part 25, and a water supply pipe provided with a storage tank 30 for storing tap water 29 and an on-off valve A31 connected to the upper part of the storage tank 30 for supplying tap water. 32 and a drain pipe 34 provided with an open / close valve B33 for discharging the stored tap water 29 connected to the bottom surface of the storage tank 30 to the sewage.

  Reference numeral 35 denotes an air circulation passage in which the garbage processing unit 25, the condensing unit 28, and the air blowing means 36 (fan) communicate with each other in a circulating manner. Of the air circulation passage 35, 35 </ b> A is an air circulation passage on the outflow side from the garbage processing unit 25. The tap water 29 is stored in the storage tank 30 with the inlet A <b> 37 opened to the garbage processing unit 25 and the outlet A <b> 38. In addition, it faces the upper space of the storage tank 30 toward the drain pipe 34. Reference numeral 35B denotes a ventilation circulation passage on the inflow side to the garbage processing unit 25. The inlet B39 faces the upper space of the storage tank 30, and the outlet B40 is opened to the garbage processing unit 25.

  Reference numeral 41 denotes a heating means for heating the air from the condensing unit 28, which may perform a constant temperature adjustment using a general sheathed heater or a mica heater, but may also perform an automatic adjustment using a PTC heater. Reference numeral 42 denotes a water level detection unit that detects the water level of the stored tap water 29 provided in the condensing unit 28. 43 is an outside air intake means for taking in outside air provided in the garbage processing unit 25, and is provided with an on-off valve C44.

  The operation of the garbage drying processing apparatus configured as described above will be described.

  First, when garbage generated in the sink 21 of the kitchen is put into the crushing device 22 and tap water is poured, the crushing device 22 starts driving. The crushing device 22 crushes the garbage, mixes it with tap water to form a solid liquid, and this solid liquid flows into the solid-liquid separation device 23.

  The solid-liquid separator 23 separates the juice and tap water adhering to the crushed garbage and drains it into the sewage from the solid-liquid drain pipe 24, while the crushed garbage is separated and discharged to the garbage processing unit 25. At the same time, the air blowing means 36 forms an air flow (for example, 10 to 100 L / min) that circulates between the garbage processing unit 25 and the condensing unit 28 through the air circulation passage 35.

  Further, the geared motor 27 is driven periodically (for example, at intervals of 15 minutes) to rotate the stirring means 26 (about 1 minute) to stir the crushed garbage. Then, the heating means 41 provided in the inflow-side air circulation passage 35B heats the air, and the dried air whose temperature has increased and the relative humidity has decreased is discharged from the outlet B40 of the inflow-side air circulation passage 35B to the garbage processing unit 25. Spout to dry garbage. In addition, since the air which ejected to the garbage processing part 25 flows through the inner surface of the garbage processing part 25 and raises temperature, it can suppress that condensed water adheres to the inner surface of the garbage processing part 25.

  The operations of the crushing device 22, the solid-liquid separation device 23, the stirring means 26, the air blowing means 36, and the heating means 37 are controlled by a control means (not shown).

  Subsequently, the air containing a large amount of steam generated from the garbage flows into the inlet A37 of the outlet circulation passage 35A by the blowing means 36. The air containing a large amount of steam is ejected from the outlet A38 of the outflow side air circulation passage 35A to the condensing unit 28, directly collides with the tap water 29 stored in the storage tank 30, and then stored in the foamed tap water. 29 flows along the surface. At that time, the stored tap water 29 is cooled with water, and the temperature of the air rapidly decreases, the saturated vapor pressure of the air decreases, and the vapor in the air condenses. The condensed water is mixed with the stored tap water 29 directly or after adhering to the inner surface of the condensing part 28.

  That is, air containing a large amount of steam generated from garbage is not air-cooled by outside air, but directly water-cooled with a liquid having high thermal conductivity, tap water 29, so that the condensing capacity of the condensing unit 28 is high.

  Specifically, even when a large amount of garbage is input from the solid-liquid separator 23 to the garbage processing unit 25 and a large amount of steam is generated in the garbage processing unit 25, a large amount of steam is condensed in the condensing unit 28. Therefore, a large amount of garbage can be dried in a short time.

  Further, the condensed air (saturated vapor pressure) flows into the inlet of the blow-in circulation passage 35B on the inflow side to the garbage processing unit 25 to form air circulation. On the other hand, since the odor component (for example, trimethylamine) contained in the steam generated from the garbage is dissolved in the condensed water or the stored tap water 29, the odor is suppressed.

  In addition, since the condensed water acidified with the sulfur and nitrogen derived from garbage is diluted from the tap water 29 stored in large quantities compared with this condensed water, there is no problem.

  Moreover, since the water level detection part 42 is controlled by the control means (not shown) to stop the air blowing means 36 when detecting the water level, the liquid level of the tap water 29 stored in the storage tank 30 is stabilized. Thus, the detection accuracy of the water level detection unit 42 is improved. On the other hand, if the condensed water continues to be mixed with the stored tap water 29, the stored tap water 29 naturally rises in level. The water level detection unit 42 detects the water level as appropriate (for example, at intervals of 15 minutes), and when the output of the water level detection unit 42 exceeds a predetermined threshold value, the on-off valve B33 and the on-off valve C44 are opened, and the outside air intake means 37 Since the outside air is taken in, the garbage processing unit 25 can be prevented from becoming negative pressure, and the stored tap water 29 can be smoothly drained from the drain pipe 34.

  Next, after closing the on-off valve B33, the on-off valve A31 is opened, and the tap water is again stored in the storage tank 30 from the water supply pipe 32. Subsequently, the on-off valve A31 and the on-off valve C44 are closed to complete the replacement of the tap water 29.

  As a result, the upper space of the storage tank 30 becomes narrow, and particularly when the storage tank 30 is full, it is possible to prevent the air flow from being delayed due to the blockage of the outlet A38 of the blower circulation passage 35A and the inlet B39 of 35B.

  The operations of the on-off valve A31, the on-off valve B33, and the on-off valve C44 are controlled by a control means (not shown) according to the output of the water level detection unit 42. In addition, when the water level of the storage tank 30 can be grasped visually or when the water level detection unit 42 is notified, the on-off valve A31, on-off valve B33, and on-off valve C44 may be manually operated.

  Moreover, since the water level of the stored tap water 29 has a substantially positive correlation with the temperature and the odor component concentration, the stored tap water 29 is replaced when the water level of the stored tap water 29 becomes high. The temperature and the odor component concentration are controlled within a certain range, the condensing capacity of the condensing unit 28 is stabilized, and the odor is suppressed. That is, it is possible to prevent the condensed water from continuing to be mixed with the stored tap water 29, the temperature of the stored tap water 29 and the odor component concentration being increased, and the condensing capacity of the condensing unit 28 and the solubility of the odor component from being lowered.

  Further, when the tap water 29 stored from the drain pipe 34 is drained, steam-containing air is drawn into the drain pipe 34 by the drained tap water 29, and the air is discharged from the outlet A38 of the blower circulation passage 35A to the drain pipe 34. Since the air is ejected toward the entrance of the air, the air becomes bubbles and is discharged together with the stored tap water 29.

  As a result, an odor component (for example, methyl mercaptan) that is difficult to dissolve in the stored tap water 29 is exhausted, and the catalyst deodorizing unit as in the conventional example is not necessary. As a result, it is not necessary to heat the catalyst to 400 ° C. or higher, the heating means 41 may have a small capacity, and the heat insulation may have a simple configuration, so that the cost can be reduced. In addition, since air does not become hotter than necessary, it is possible to prevent a large amount of odorous components from being generated due to high-temperature pyrolysis of garbage.

  Further, since the blowing means 36 is controlled by the control means (not shown) to stop while the stirring means 26 is rotating and stirring the garbage, the fine raw food dried by the stirring of the stirring means 26 is controlled. Garbage can be prevented from being scattered and carried to the circulating air. As a result, fine dry garbage is not accidentally discharged from the garbage processing unit 25, and the garbage does not adhere to the condensing unit 28, the air blowing unit 36, and the heating unit 41.

  Further, when the garbage discharged to the garbage processing unit 25 is dried, the steam generated from the garbage is reduced, and naturally the generation of condensed water in the condensing unit 28 is also reduced. Therefore, when the output of the water level detection unit 42 does not increase for a predetermined period (for example, 3 hours), it can be determined that the garbage in the garbage processing container 25 has been sufficiently dried and reduced, and the geared motor 27, the air blowing means 36, and the heating means. Energy saving can be achieved by controlling by means of control means (not shown) to stop 41.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. FIG. 2 shows a configuration diagram of a garbage drying processing apparatus according to Embodiment 2 of the present invention. Note that the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The difference from the first embodiment is that heating means 45 is additionally provided on the outer surface of the garbage processing unit 25, and the outlet A38 of the blast circulation passage 35A on the outflow side is connected to the bottom surface of the storage tank 30 to store the stored tap water. The condensing temperature detecting unit 46 for detecting the temperature 29 and the baffle plate 47 are provided below the water surface of the condensing unit 28.

  First, when garbage is thrown into the garbage processing unit 25, an air flow (for example, 4 to 10 L) is circulated between the garbage processing unit 25 and the condensing unit 28 through the air circulation passage 35 by the blowing unit 36 (air pump). / Min). Then, the heating means 41 provided in the inflow side air circulation passage 35B heats the air, the relative humidity decreases due to the temperature rise, and the dried air is ejected to the garbage processing unit 25 to dry the garbage. In addition, the heating means 45 provided on the outer surface of the garbage processing unit 25 dries the garbage through the garbage processing unit 25. Subsequently, the air containing a large amount of steam generated from the garbage flows into the inlet A37 of the outlet circulation passage 35A by the blowing means 36. Moreover, since the heating means 45 raises the temperature of the garbage processing part 25 directly from the outer surface of the garbage processing part 25 and the heating means 41 via air, condensed water adheres to the inner surface of the garbage processing part 25. Can be prevented.

  Next, air is ejected from the outlet A38 of the outflow side air circulation passage 35A opened in the tap water 29 stored in the condensing unit 28, and the stored tap water 29 collides with the baffle plate 47 to cause a large number of bubbles. Therefore, the contact area (bubble surface area) between the stored tap water 29 and the air becomes very wide. As a result, the tap water 29 in which the air is stored is sufficiently cooled with water and the temperature is rapidly lowered, and the saturated vapor pressure of the air is lowered. Therefore, a large amount of vapor in the air is condensed.

  The condensed water is mixed with the stored tap water 29 directly or after condensing and adhering on the inner surface of the upper space of the condensing unit 28 after passing through the stored tap water 29.

  The amount of air is small compared to the first embodiment because of the large burst noise of bubbles, but the contact area between the stored tap water 29 and air (the surface area of the bubbles) is very large, so the condensing unit 28 is compact. Since the odor component contained in the steam is sufficiently dissolved in the stored tap water 29, the odor can be reliably suppressed.

  In addition, since the condensed water acidified with the waste-derived sulfur and nitrogen is diluted from a large amount of stored tap water 29 compared to this condensed water, there is no particular problem.

  However, conversely, the stored tap water 29 is heated by air passing through as bubbles and the temperature rises. When the output of the condensing temperature detection unit 46 exceeds a predetermined threshold value, the on-off valve B33 and the on-off valve C44 are opened, and outside air is taken in from the outside air intake means 37, so that the garbage processing unit 25 becomes negative pressure. The stored tap water 29 can be smoothly drained from the drain pipe 34.

  Next, after closing the on-off valve B33, the on-off valve A31 is opened, and the tap water is again stored in the storage tank 30 from the water supply pipe 32. Subsequently, the on-off valve A31 and the on-off valve C44 are closed to complete the replacement of the tap water 29.

  As a result, it is possible to prevent the condensing capacity of the condensing unit 28 from being lowered due to a decrease in the water cooling capacity of the stored tap water 29.

  The operations of the on-off valve A31, the on-off valve B33, and the on-off valve C44 are controlled by a control means (not shown) according to the output of the water level detection unit 42.

  Moreover, since the temperature of the stored tap water 29 has a substantially positive correlation with the water level and the odor component concentration, the water level of the stored tap water 29 and the odor component concentration are controlled within a certain range, and the air flow is delayed. And odor can be suppressed. That is, when the temperature of the stored tap water A is increased, the stored tap water A is replaced, so that the upper space of the condensing unit 28 is narrowed. Especially when the water is full, the air is blocked by the outlet of the air circulation passage 33A and the inlet of the 33B. It is possible to prevent the flow of stagnation and the odor component concentration from increasing and the solubility of the odor component from decreasing.

  Furthermore, when the tap water 29 stored from the drain pipe 34 is drained, the tap water that is drawn into the drain pipe 34 by the drained tap water 29 and stores a large number of air bubbles passing through the stored tap water 29 is stored. 29, the odorous component (for example, methyl mercaptan) which is difficult to dissolve in the stored tap water 29 can be exhausted, and the catalyst deodorizing part as in the conventional example is not required.

  As a result, it is not necessary to heat the catalyst to 400 ° C. or higher, the heating means 41 may have a small capacity, and the heat insulation may have a simple configuration, so that the cost can be reduced. In addition, since air does not become hotter than necessary, it is possible to prevent a large amount of odorous components from being generated due to high-temperature pyrolysis of garbage.

  In the second embodiment, the heating means 41 provided on the outer surface of the garbage disposal unit 25 is added to the heating means 41 provided in the air circulation passage 35B. However, there is no heating means 41 and the heating means 45 is provided. The same effect can be obtained even in the case of only the case.

  Furthermore, in the description in the first and second embodiments, the garbage generated in the sink 21 of the kitchen is put into the crushing device 22, and the solid-liquid mixed with tap water is separated by the solid-liquid separation device 23. Although the structure having the process of drying the separated crushed garbage in the garbage processing unit 25 has been described as an example, the process of the above-described kitchen sink 21, crushing device 22, and solid-liquid separation device 23 is not provided. Even when the garbage is directly put into the garbage processing unit 25, the above-described effects of the present invention can be similarly exhibited.

  Further, the tap water 29 stored in the condensing unit 28 can obtain the same effect even if it is juice or tap water attached to the garbage drained from the solid-liquid drain pipe 24.

  As mentioned above, according to this invention, the garbage drying processing apparatus which aimed at the condensation capability improvement of the condensation part and the simplification of an apparatus is provided.
