[0009]

In the waste disposal apparatus according to the first aspect of the present invention, the waste is introduced into the drying means, and is heated to a high temperature (for example, about 600
C), and the heated gas is introduced into the drying means. In the drying treatment means, the waste is pulverized into sludge by appropriate movement such as rotation, and the waste is dried by efficiently transmitting the heat of the heated gas to the waste. The material is further pulverized and carbonized, and finally the waste is pulverized.

The waste in powder form is discharged from the drying means together with the exhaust gas and introduced into the powder separating means. The powder separating means includes, for example, a dust collecting cyclone, and separates and collects powdery waste from exhaust gas. The waste collected here is an odorless powder that has been carbonized, and naturally has an extremely small amount as compared with the amount before the treatment. Further, the exhaust gas from the powder separating means is introduced into the deodorizing means.
The deodorizing means includes a deodorizing catalyst such as platinum, for example.
The odor in the exhaust gas is removed and only the exhaust gas that has become odorless is discharged.

In addition, the waste disposal apparatus performs the above-described waste drying process while generating power by the heated gas generating means, and stores the electric power in the power supply means. To supply power. Further, the waste disposal apparatus controls a series of operations of the heating gas generating unit, the drying processing unit, the powder separating unit, and the deodorizing unit by the main control unit. For this control, it is possible to perform appropriate control based on the outputs of the sensors using sensors attached to each means.

As described above, in the waste drying apparatus, if the fuel for the heated gas generating means is prepared, no external power supply is required, and the waste is generated while generating power by itself. The drying process is automatically performed, and the waste can be collected as odorless powder and the exhaust gas is odorless, so that there is almost no influence on the surrounding environment.

According to a second aspect of the present invention, an exhaust temperature of the drying means is measured by a temperature sensor, and a main control means determines a drying state of the waste based on the exhaust temperature. to decide. In other words, in the early stage of the drying process, the heat of the heated gas is taken away exclusively by drying the waste,
The exhaust temperature of the drying means also decreases. Then, as the drying process proceeds, the exhaust temperature of the drying means increases. Therefore, if the exhaust temperature at the time when the waste is sufficiently dried to form the carbonized powder is determined in advance, it is possible to determine the drying processing state of the waste by monitoring the exhaust temperature of the drying processing means. obtain.

According to a third aspect of the present invention, there is provided a waste-drying apparatus, comprising a collection box, a toilet unit, a toilet tub of a storage-type toilet, a sludge tank of various wastewater treatment apparatuses, and the like. And collects the waste, and transports the waste from the waste recovery means to the drying means by the waste transport means. At this time, the waste transport means temporarily stores the waste from the waste recovery means and transports a predetermined amount of waste to the drying means, so that the waste recovery means is continuously operated. Alternatively, even when used intermittently, a predetermined amount of waste is always dried in a constant cycle.

According to a fourth aspect of the present invention, in the waste drying apparatus, the waste transporting means vacuum transports the waste from the waste recovery means to the reserve tank via the transfer tank, and stores the waste in the reserve tank. Temporarily store waste. Then, a predetermined amount of waste is vacuum-transported from the reserve tank to the drying means via the chute tank, so that the waste can be dried in a certain cycle. At this time, the waste transporting means does not transport the waste with the force of water, but performs the transport of the waste by evacuation, and when the waste recovery means is a toilet unit, In addition, even if the amount of washing water is reduced, the transfer of the waste is reliably performed.

According to a fifth aspect of the present invention, in the waste drying apparatus, the waste is put into the drying container by the drying means, and the high temperature heating is performed from the heated gas duct while rotating the drying container. A gas is introduced, and the waste is crushed by a ball accommodated in a drying treatment container while drying is performed.
At this time, since the drying processing container has a tapered surface which is held in an inclined state and is substantially horizontal below the ball, the ball rolls so as to roll down to the horizontal portion of the tapered surface with rotation. Thus, the dried waste is pulverized, and the heat of the heated gas is effectively transmitted to the waste.

In the waste disposal apparatus according to the sixth aspect of the present invention, the heating gas duct is arranged so that the exhaust port is buried in the initial waste stored in the drying treatment container, so that the high temperature is maintained. Will be blown into the waste,
The heat of the heated gas is transferred very effectively to the waste. Further, since the heating gas duct is fixed to the rotatably driven drying processing container, the heating gas duct itself also functions as a means for crushing and stirring the waste.

In the waste processing apparatus according to claim 7 of the present invention, in the drying processing container of the drying processing means, for example, an air flow path is provided in a fixed lid, and the rotating container body and the fixed lid are connected to each other. Pressurized air is injected from the air flow path between the sliding contact surfaces. At this time, the pressure of the pressurized air is higher than the internal pressure of the drying processing container. Thereby, the space between the two sliding contact surfaces is sealed by the pressurized air, thereby preventing the odor from leaking from the drying processing container and reducing the frictional force at the sliding portion.

In the waste drying apparatus according to the eighth aspect of the present invention, the flow rate adjusting valve, the drying processing means, and the powder separating means are provided on the inlet side of the exhaust duct in the deodorizing means with the heating gas from the heating gas generating means. And a heating gas introduction path for directly introducing the heating gas from the heating gas generation means via another flow control valve. Then, in removing the odor in the exhaust gas of the powder separating means in the deodorizing means, the temperatures of the inlet side and the outlet side in the exhaust duct are measured by a temperature sensor, and based on the output, the main control means controls the respective flow control valves. Control.

That is, as described above, the exhaust temperature of the drying means changes with the progress of the drying processing. More specifically, the temperature changes from 60 to 250C in the initial stage, 250 to 350C in the middle stage, and from 350 to 420C in the latter period. Therefore, the exhaust temperature of the powder separating means downstream of the drying means also changes. On the other hand, in the case of a deodorizing catalyst using, for example, platinum, it is necessary to maintain the reaction temperature at a certain level or higher (for example, 300 ° C. or higher).

Therefore, in the waste disposal apparatus, the gas temperature at the inlet and the gas temperature at the outlet of the deodorizing catalyst in the deodorizing means are measured until the temperature measured by the temperature sensor at the outlet exceeds a predetermined value. During that time, that is, until the deodorizing catalyst reaches a predetermined temperature, the odor control valve between the heated gas generating means and the drying processing means is closed, whereby the malodor is discharged to the outside through the powder separating means and the deodorizing means. And operating the flow control valve of the heating gas introduction path in the opening direction to directly introduce the high-temperature heating gas into the exhaust duct, thereby heating the deodorizing catalyst.

Then, when the temperature of the deodorizing catalyst reaches a predetermined temperature and the temperature measured by the temperature sensor on the outlet side exceeds a predetermined value, the flow control valve between the heating gas generating means and the drying processing means is opened to open the drying processing. During the drying process in which the temperature of the exhaust gas introduced from the powder separating means gradually increases, the temperature measured by the temperature sensor on the inlet side of the deodorizing catalyst and the temperature measured by the temperature sensor on the outlet side are set to the respective temperatures. By closing or opening the flow control valve in the heating gas introduction passage between the heating gas generation means and the drying processing means and between the heating gas generation means and the deodorizing means so as to fall within the range, the inflow amount of the exhaust gas, that is, the heat inflow Adjust and control the volume.
Thereby, the reaction temperature of the deodorizing catalyst is kept almost constant.

In the waste drying treatment apparatus according to the ninth aspect of the present invention, when the heating gas generating means is a gas turbine engine having a power generation unit, the temperature of the exhaust gas, that is, the temperature of the heating gas changes depending on the external temperature and load. Has characteristics. The power load increases the temperature of the heated gas by adding it. Therefore, the temperature of the heated gas is measured by the temperature sensor, and when the temperature of the heated gas decreases, at least one of the power generation unit and the flow control valve is controlled by the main control unit. For example, the main control unit applies a power load to the power generation unit of the heating gas generation unit to increase the temperature of the heating gas. If the temperature of the heating gas still does not increase to a predetermined value, the flow control valve is controlled to be closed. Thus, an exhaust pressure load is applied to the heating gas generating means to increase the temperature of the heating gas.

According to a tenth aspect of the present invention, the input / output current value of the storage battery of the power supply is measured by the current sensor, and the current value from the current sensor is measured by the main control means in V / F. By converting and counting up and down the pulses, the input / output current of the storage battery power supply means is integrated, and the power supply means is controlled by recognizing the integrated value.

That is, a method of controlling the state of charge by detecting the voltage of the battery is generally used for charging the battery. In this method, however, the relationship between the voltage of the battery and the depth of discharge is constantly changed depending on the temperature. As a result, the depth of discharge could not be kept within a certain range, resulting in a shorter battery life. In contrast, in the waste drying apparatus, the current value from the current sensor is V / F converted, the number of pulses is counted, and the input / output current of the storage battery is counted to recognize the current value. In addition, it is possible to control the depth of discharge of the storage battery, so that the service life of the storage battery can be extended.

In the heating gas temperature control method in the heating gas generation device according to the eleventh aspect of the present invention, in the heating gas generation means having a power generation function and generating the heating gas, the temperature of the generated heating gas is set to the external temperature. And the load changes, the temperature of the heated gas is measured, and when the measured temperature falls below a predetermined value, at least one of the power load on the power generation unit and the exhaust pressure load of the heated gas is performed. For example, by increasing the temperature of the heating gas by applying a power load to the power generation unit, and by applying an exhaust pressure load of the heating gas to the heating gas generation means when the temperature rise is insufficient. Increase the temperature of the heated gas.

The waste drying apparatus treats the illumination in the toilet unit 8 and drives the vacuum pump 8 with the electric power stored in advance, and vacuum-transports the waste from the toilet unit 8 to the reserve tank 57 by the transfer tank 60. Then, when the internal capacity detection sensor 77 detects that a predetermined amount or more of waste material has been stored in the reserve tank 57, the heating gas generating means 2 is activated, and the chute tank 63 causes the drying tank to be removed from the reserve tank 57. 19, a predetermined amount of waste is vacuum-transported.

At this time, the pipes 58 and 61 connected to the reserve tank 57 are connected to the pipe 13 of the toilet unit 8.
, Which have a large inner diameter are used to prevent clogging of waste in each pipe. Further, in the transfer tank 60 and the chute tank 63, the waste is vacuum-transported, so that the transport is reliably performed without the need for the force of the wash water, and the amount of the wash water in the toilet unit 8 is saved. I can do it.
Further, the evacuation at the time of evacuation is performed in the activated carbon box 71.
Absorbs the odor and discharges it to the outside.

In the drying processing means 3, when the waste is thrown in, the deodorizing catalyst 50 of the deodorizing means 5 described later is heated to a predetermined reaction temperature, and then the container driving motor 25 rotates the container body 19A. At the same time, a high-temperature (for example, about 600 ° C.) heating gas generated by the heating gas generation unit 2 is introduced from the heating gas duct 21.

At this time, in the drying processing container 19, the lower end of the heated gas duct 21 is buried in the waste Q as shown in FIG. The material is agitated and the heat of the heated gas is efficiently transmitted to the waste. Moreover, since the drying processing container 19 has the tapered surface 23 which is held in an inclined state and is substantially horizontal below the drying processing container 19, the plurality of balls 22 are rotated by the rotation of the drying processing container 19. It rolls so as to roll down to a horizontal portion, thereby crushing the waste and efficiently transmitting the heat of the heated gas to the waste. Further, the heated gas duct 21 buried in the waste material also functions as a means for pulverizing and stirring the waste material, which can contribute to prompt drying of the waste material.

As described above, in the drying treatment means 3, initially, the waste is pulverized into sludge while being pulverized, and then the dried waste is swirled by a jet of a heated gas and burned. The waste is carbonized into powder.

During the drying process, in the drying process container 19, the bellows 35 absorbs the elongation of the container main body 19A in the rotation axis direction due to the pressure of the heated gas, and the cover 19
B. Pressurized air having a pressure higher than the internal pressure of the drying container 19 is injected into the air passage 36 of B, and the compressed air is injected between the sliding contact surface of the rotating sliding member 30 and the sliding contact surface of the fixed sliding member 31. To supply. As a result, the space between the sliding members 30 and 31 is sealed with the pressurized air, and leakage of odor from the drying processing container 19 is completely prevented. Further, the frictional force of the sliding portion is reduced by the seal of the pressurized air, so that the sliding members 30 and 31 are prevented from being worn and the load on the container driving motor 25 is reduced.

Furthermore, in the above-mentioned drying treatment, the heat of the heated gas is mainly taken away by the drying of the waste in the initial stage, so that the exhaust temperature of the drying treatment means 3 also becomes low. Then, the exhaust temperature of the drying means 3 rises as the drying processing progresses. Specifically, the initial stage is 60 to 250 ° C, and the middle stage is 250 ° C.
３５０350 ° C., and later changes to 350-420 ° C.

Therefore, in the waste drying apparatus, the exhaust temperature of the drying means 3 when the waste is sufficiently dried and turned into powder is obtained in advance, and in the actual drying processing, The temperature of the exhaust gas of the drying means 3 is measured by the temperature sensor 46, and the measured temperature is inputted to the main control means 6
, The state of the drying process is automatically determined.

The powdery waste that has been subjected to the drying treatment as described above is exhausted from the drying treatment means 3 together with the powder separation means 4.
And is separated by the dust collecting cyclone 47 of the powder separating means 4 and stored in the collection box 48. At this time, the amount of the powdery waste is naturally much smaller than the initial amount, and it is odorless and has no possibility of adversely affecting the surrounding environment. Further, the exhaust gas from the powder separating means 4 is introduced into an exhaust duct 51 of the deodorizing means 5, and the odor is removed by the oxidation-reduction action of the deodorizing catalyst 50 and discharged to the outside. Therefore, there is no adverse effect on the environment due to the odor.

Here, in the deodorizing catalyst 50 using platinum,
It is necessary to keep the reaction temperature at, for example, 300 ° C. or higher.
On the other hand, since the exhaust temperature of the drying unit 3 changes during the drying process as described above, the exhaust temperature introduced from the powder separating unit 4 to the deodorizing unit 5 also changes. That is, at the beginning of the drying process, the deodorizing catalyst 50 is used.
Exhaust gas at a temperature clearly lower than the reaction temperature is introduced into the deodorizing means 5.

Therefore, in the waste disposal apparatus, the temperature sensors 52 and 53 of the deodorizing means 5 measure the gas temperature on the inlet side and the gas temperature on the outlet side of the deodorizing catalyst 50. The flow control valve 44 of the heating gas duct 21 and the flow control valve 54 of the heating gas introduction path 55 are controlled based on the temperature.

That is, until the temperature measured by the temperature sensor 53 on the outlet side becomes a predetermined value or more, that is, until the deodorizing catalyst 5
Until 0 reaches a predetermined temperature, the heating gas duct 2
By closing the first diversion adjusting valve 44, the odor is prevented from being discharged to the outside through the powder separating means 4 and the deodorizing means 5, and the flow adjusting valve 54 of the heating gas introduction path 55 is operated in the opening direction. A high-temperature heating gas is directly introduced into the exhaust duct 51, thereby heating the deodorizing catalyst 50.

When the temperature of the deodorizing catalyst 50 reaches a predetermined temperature and the temperature measured by the temperature sensor 53 on the outlet side exceeds a predetermined value, the flow control valve 4 of the heated gas duct 21
4, the heated gas is introduced into the drying means 3 to start the drying processing. During the drying processing in which the temperature of the exhaust gas introduced from the powder separating means 4 into the exhaust duct 51 gradually increases, the inlet side is opened. And temperature sensors 52 and 53 on the outlet side
The flow control valve 54 of the heated gas introduction path 55 is operated in the closing direction so that the temperature measured by the powder separation means 4 is maintained within a predetermined range. Increase the inflow of exhaust gas. Thereby, the temperature in the exhaust duct 51 is reduced by the deodorizing catalyst 50.
Above the reaction temperature. In addition,
The flow rate adjusting valves 44 and 54 are not necessarily controlled in only one direction during the progress of the drying process, but are appropriately controlled to open and close based on the temperature measured by the temperature sensors 52 and 53. The flow rate of the exhaust gas, that is, the heat flow rate is adjusted.

In the waste disposal apparatus, the temperature of the heated gas generated by the heated gas generating means (gas turbine engine) 2 changes depending on the external temperature and load.
The temperature of the heated gas is measured by a temperature sensor 75 provided in the exhaust pipe 74, and the main control unit 6 controls at least one of the power generation unit 1 and the flow control valve 76 of the exhaust pipe 74 based on the measurement result.

That is, when the temperature of the heated gas decreases, as shown in FIG. 4, a power load is applied to the power generation unit 1 by a command from the main control means 6 to increase the temperature of the heated gas, and the temperature rise is insufficient. In the case of, the flow rate adjusting valve 76 is further operated in the closing direction by a command from the main control means 6 to apply an exhaust pressure load to the heating gas generation means 2 to increase the temperature of the heating gas. As a result, the temperature of the heated gas is maintained substantially constant without being influenced by the external temperature or the load, and the variation in the drying processing time is prevented.

Further, in the waste drying apparatus, the current sensor 80 measures the input / output current value of the storage battery 79 of the power supply means 7, and the main control means 6 controls the current sensor 8.
The current value from 0 is V / F converted, and the pulse is counted up and down, thereby integrating the input / output current of the storage battery 79 and recognizing the integrated value. Thereby, the storage battery 79
Can be controlled, and the life of the storage battery 79 can be extended.

As described above, the above-described waste drying apparatus does not require any external power supply, and controls and drives the devices of each means while generating power by itself, thereby automatically discharging the waste. In a short time, the powder is dried to form an odorless carbonized powder, and the exhaust gas is odorless and has no adverse effect on the environment. In the waste transporting means 9 in particular, since the waste is temporarily stored and a predetermined amount of waste is transported to the drying means 3, the toilet unit 8 is operated continuously or intermittently. However, the drying process can be continuously performed in a fixed cycle without being affected by the operation state.

Accordingly, the waste drying apparatus of the above-described embodiment realizes a self-contained toilet system which is very suitable for use in a place where the facilities of electricity, water and sewage are not provided. The configuration of the waste disposal apparatus according to the present invention is not limited to the above-described embodiment, and each unit can be appropriately changed. Two internal combustion engines for processing and power generation may be used, and the waste collection means may be configured to collect waste such as garbage and sludge generated in wastewater treatment. .

Further, in the above embodiment, the control performed by the main control means 6 when the temperature of the heating gas from the heating gas generating means 2 is reduced by an external temperature or a load, that is, the temperature of the heating gas is The control for performing at least one of the power load on the power generation unit 1 and the exhaust pressure load by the flow regulating valve 76 when the measured temperature falls below a predetermined value is performed by a method for controlling the temperature of the heated gas in the heated gas generator. The present invention can also be applied to a heated gas generator other than the heated gas generator 2 of the waste drying apparatus.
