- Figure 16 is a schematic diagram showing a conventional garbage disposal system.
- FIG. 1 is a schematic diagram of a garbage processing apparatus 1 according to a first embodiment of the present invention.
- the garbage processing apparatus 1 has a processing chamber 10 for processing garbage 2 by microbial decomposition, an intake path 20 for introducing fresh air from the outside into the processing chamber through an air inlet of the processing chamber, and a processing chamber. It includes an exhaust path 21 connected to the discharge port 14 of the chamber and having an exhaust port at the other end, and a circulation path 22 for returning the air in the exhaust path to the processing chamber.
- the processing room 10 is equipped with a garbage stirrer 11, a water content sensor 60 for measuring the water content of the garbage, and air with an unpleasant odor generated by the biodegradation of the garbage.
- There is a blower fan 13 for sending air to the exhaust path.
- the stirring device and the moisture content sensor may be omitted.
- the dehumidifier 30 includes a dehumidifier 31 and a heater 32 as a regenerating means for regenerating the dehumidifier by removing moisture adsorbed on the dehumidifier.
- solid acids such as silica gel, zeolite and aluminum silicate, calcium chloride and calcium carbonate can be used. These dehumidifiers have the ability to adsorb not only water vapor but also ammonia, which is the main component of odor. In particular, it is preferable to use silica gel which has a high removal rate of ammonia and trimethylamine, which are main components of malodors, in addition to moisture.
- a dehumidifier using a dehumidifier unlike a dehumidifier that removes and condenses moisture in the air by dehydrating the refrigeration cycle, thermoelectric conversion element, and air, does not generate dew water in which the odorous components are dissolved. There is an advantage that there is no need for an operation of discarding the condensed water. Therefore, there is no problem of putrefaction odor generated from dew condensation water.
- the circulation path 22 branches off from the exhaust path 21 at a branch section 23 located downstream of the dehumidifier 30 and extends into the processing chamber 10.
- An air flow adjusting member 40 for changing the amount of air returned from the exhaust path 21 to the processing chamber via the circulation path 22 is provided at the branch portion.
- an electric damper can be used as the air volume adjusting member.
- the operation of the air volume adjusting member 40 is controlled by the control unit 3. During normal use of the garbage disposal 1, the control unit 3 discharges a part of the air provided from the dehumidifier 30 to the outside via the exhaust path, and the remaining air is supplied to the circulation path 2.
- the air volume adjusting member 40 is set to the first position so that the air volume adjusting member 40 is returned to the processing chamber 10 via 2 again.
- the amount of air introduced into the processing chamber via the intake path is equal to the amount of air discharged outside via the exhaust path 21. Therefore, the first position of the air volume adjusting member 40 is based on the assumption that the amount of air introduced into the processing chamber 10 via the intake path 20 is based on the amount of oxygen necessary to perform microbial decomposition in the processing chamber. It is determined so that the amount of air becomes as follows.
- the air volume adjusting member 40 By controlling the air volume adjusting member 40, the amount of exhaust air from the garbage disposal device 1 can be significantly reduced.

- the control unit 3 controls the circulation path 22 to be cut off at the branch 23.
- a moisture sensor (not shown) that detects the amount of water adsorbed on the silica gel and outputs a first control signal to the control unit 3 when the amount of adsorbed water exceeds a predetermined amount of water.
- the control unit 3 is provided with an ammonia sensor (not shown) that detects the amount of ammonia adsorbed on the force gel and outputs a second control signal to the control unit 3 when the amount of adsorbed ammonia exceeds a predetermined amount of ammonia. Starts the heater 32 based on one of the first control signal and the second control signal, sets the air volume adjusting member 40 to the second position, and starts the regeneration operation. It is also possible to use only a moisture sensor without using an ammonia sensor.
- a deodorizing device 50 for removing odor from air that is to be discharged to the outside via the exhaust path is provided downstream of the dehumidifying device 30 in the exhaust path 21. Have been.
- the deodorizing device 50 is arranged downstream of the branch portion 23. Most of the air sent from the dehumidifier is sent to the circulation path, and the amount of air discharged to the outside is small. Therefore, the garbage disposal of the present invention does not require a large-sized deodorizer, and as a result, The size and energy saving of the entire waste disposal system can be improved.
- An additional deodorizer for deodorizing small amounts of odor components other than N-type odor components such as ammonia / trimethylamine, for example, sulfur compounds, etc., on the exhaust path 2 It may be provided between the first dehumidifier 30 and the branch portion 23. It is particularly preferable to use activated carbon as an adsorbent in the additional deodorizer.
- the deodorizer 50 used in this embodiment is composed of an oxidation catalyst 51 supporting a noble metal on an oxide such as alumina and a heater 52.
- deodorizers such as adsorbents, ozone decomposers, and microbial deodorizers, or deodorizers that combine them may be used.
