Abstract

PURPOSE:To provide a waste disposal device which is of a simple constitution and dries and disposes of it without smoke and odor by providing a control means which stops a heating means in a waste receiving and storing chamber by the signal from a temperature sensor which is provided on a catalyst and then stops a blower after a certain time has passed. CONSTITUTION:It is possible to detect the end of drying of a waste 2 when a rise in the temperature of a catalyst 10 is detected by a temperature sensor 12. When the end of drying is detected by the signal from the temperature sensor 12, the oscillation of a magnetron 3 is stopped by a control section 15. Because of the heat capacity possessed by the waste 2 its temperature does not drop rapidly even if the oscillation of the magnetron 3 is stopped. Under this situation combustible gases are generated for a while from the waste 2. Now a blower 6 is operated for a certain time after stopping the oscillation of the magnetron 3 to supply the air for transportation to waste receiving and storing chamber 1. And, after combustible gases that are generated are all disposed of with the catalyst 10, if the operation of the blower 6 is stopped by the control section 15, the waste 2 is dried and disposed of without developing smoke and odor.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for processing waste such as food waste, combustible garbage, human waste, etc. generated at home or in business.

BACKGROUND OF THE INVENTION In recent years, the disposal of garbage has become a socially important issue in order to prevent environmental pollution.

By the way, there are two types of conventional waste processing equipment: a mechanical processing equipment called a disposer and a combustion type processing equipment called an incinerator. Mechanical processing equipment, or disposers, uses a rotating flywheel to blow away trash, shredder to crush it, and a hammer to crush it.
This method involves disposing of it into the sewer.

On the other hand, combustion type processing devices, that is, incinerators, include batch combustion furnaces that intermittently burn waste, and continuous combustion furnaces that move waste one after another into the furnace using a belt and burn it continuously. Both types of combustion furnaces use a burner to burn gas or liquid fuel, and use the combustion heat to incinerate and dispose of waste.

Problems to be Solved by the Invention These conventional waste treatment devices have the following problems.

Disposers mechanically process garbage into small pieces, but eggs, shellfish, fibers, etc. are not decomposed and when flushed into the sewer, the wastewater contains a large amount of solids, which can clog the sewer. 9, there was a big problem that the scrubbing gave off a strange odor.

Additionally, incinerators can process many different types of waste at once.
Although it has the characteristics of significantly reducing the amount of residual processing and completely killing pathogenic bacteria, etc., it has a complex structure, large equipment, and difficult combustion control, which causes problems such as smoke and odor. It has major drawbacks such as being easy to wake up and causing environmental pollution.

An object of the present invention is to provide a waste processing apparatus which has a simple configuration and which dries waste into smoke and odor U7.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides, as a first means for solving the problems, a waste storage chamber having a means for heating waste, a catalyst located downstream thereof, and a conveying air. A temperature detecting means is provided on the catalyst, and a signal from the temperature detecting means stops the heating means for the waste storing chamber, and the blowing means is stopped after a certain period of time has elapsed. This configuration has a control means.

Still, as a second problem-solving means, the waste storage chamber has a means for heating waste, a catalyst located downstream of the waste storage chamber, and a blowing means for supplying conveying air to the waste storage chamber, A gas detection means is provided near the exit of the waste storage chamber, and control means is provided for stopping the heating means for the waste storage chamber according to a signal from the gas detection means, and then stopping the blowing means according to a signal from the gas detection means. It is structured as follows.

For production The effect of the first problem solving means is as follows.

Store waste in the waste storage room. In this state, the heating means provided in the waste storage chamber is operated and conveying air is supplied to the waste storage chamber. The temperature of the waste increases,
The water in the waste evaporates and the waste begins to dry. Once the waste is completely dry, it begins to emit flammable gases.

This combustible gas reacts with the catalyst and generates heat, raising the temperature of the catalyst. The completion of drying is detected by detecting this temperature rise, and the heating means provided in the waste storage chamber is stopped. Since the waste has heat capacity, even if the heating means is stopped, the temperature of the waste does not drop rapidly, and therefore flammable gas is generated from the waste for a while. Therefore, after the heating means is stopped, conveying air is supplied to the waste storage chamber for a certain period of time, all the generated flammable gas is treated with a catalyst, and then the blowing means is stopped to remove the waste without smoke or odor. It is a dry process.

Moreover, the second problem-solving means is as follows.

If a gas detection means is provided near the exit of the waste storage chamber, the combustible gas generated from the waste is detected, the completion of drying is detected, and the heating means provided in the waste storage chamber is stopped. Since the waste has a heat capacity, the temperature of the waste does not drop rapidly even when the heating means is stopped, and therefore flammable gas is generated from the waste for a while. Therefore, even after the heating means is stopped, conveying air is supplied to the waste storage chamber to process the flammable gas with a catalyst, and the end of generation of flammable gas is detected by the signal from the gas detection means, and the blowing means is stopped. For example, waste can be dried without producing smoke or odor.

An embodiment of the first problem-solving means of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, waste 2 is stored inside the waste storage chamber 1. As shown in FIG. The magnetron 3 is connected to the waste storage chamber 1 via a waveguide 4.

Microwaves of 2450 MHz are emitted from the magnetron 3, pass through the waveguide 4, and are irradiated to the waste storage chamber 1. A microwave transmitting member 6 is provided at the connection portion between the waveguide 4 and the waste storage chamber 1 to protect the transmitting portion of the magnetron 3.

The blower 6 supplies cooling air to the magnetron 3, and also branches some of the air through a branch pipe 7, passes through a conveying air path 8, and supplies the conveying air from an air port 9 to the waste storage chamber 1.
We are trying to supply it to

The catalyst 10 provided downstream of the waste storage chamber 1 is surrounded by a catalyst heater 11, and is kept warm so that the catalyst is constantly maintained at an active temperature. A temperature detection section 12 is provided upstream of the catalyst 10 and is configured to detect the temperature of the catalyst. The catalyst temperature detection unit 12 may be mounted in direct contact with the catalyst 1o as in this embodiment, or may be mounted in direct contact with the catalyst 1o.
It may be provided close to o. Here, catalyst temperature detection section 1
2 is a thermocouple, optical sensor, or the like that can detect temperature, light, etc., and detect the temperature of the catalyst 10. The catalyst temperature detection section 12 sends a signal to a control section 15, and the control section 15 controls the operation of the magnetron 3 and the blower 6.

In the above configuration, at the time of startup, the catalyst heating heater 11 is energized to raise the temperature of the catalyst 10 to the activation temperature in advance.

When it is confirmed by the signal from the catalyst temperature detection section 12 that the catalyst 10 has reached the activation temperature, energization of the magnetron 3 is started. The temperature of the waste 2 increases due to the microwaves, the moisture in the waste 2 evaporates, and the waste 2 begins to dry. The evaporated water is diluted with the cooling air of the magnetron 3 and exhausted from the exhaust stack 13. When the waste 2 is completely dried, the temperature of the waste 2 further increases, and the waste 2 begins to generate flammable gas.

This combustible gas reacts with the catalyst 10 to generate heat, and the catalyst 10
increase the temperature. If the temperature detection unit 12 detects this temperature rise of the catalyst 1Q, it is possible to detect the end of drying of the waste 2. When the completion of υ drying is detected by the signal from the temperature detection section 12, the control section 16 stops the transmission of the si magnetron 3. Since the waste 2 has heat capacity, the temperature of the waste 2 does not drop rapidly even if the magnetron 3 stops transmitting. For this reason, flammable gases are generated from the waste 2 for some time. Therefore, after the magnetron 3 stops transmitting, the blower 6 is operated for a certain period of time to supply conveying air to the waste storage chamber 1. After all of the generated combustible gas has been treated by the catalyst 1o, if the operation of the blower 6 is stopped by the control unit 16, the waste 2 can be dried without producing smoke or odor.

Next, an embodiment of the second problem-solving means will be described based on FIG. 2. In this embodiment, a gas detection section 14 is provided near the exit of the waste storage chamber 1.

Here, the gas detection section 14 is made of tin oxide, zirconia oxide, or the like, and can detect hydrocarbons, carbon oxide, oxygen, and the like to detect the generation of flammable gas.

When the drying is completed, flammable gas is generated from the waste 2, so that the gas detection unit 14 can detect the combustible gas generated from the waste 2 to detect the completion of the drying. When the end of drying is detected by the signal from the gas detection section 14, the control section 15 stops the magnetron 3 from transmitting the signal. Since waste 2 has heat capacity, magnetron 3
Even if the transmission of is stopped, the temperature of the waste 2 does not drop rapidly. For this reason, flammable gases are generated from the waste 2 for some time.

Even after the magnetron 3 stops transmitting, the blower 6 is operated to supply conveying air to the waste storage chamber 1 and treat the combustible gas with the catalyst 10. If the controller 15 stops the operation of the blower 6 after the end of generation of flammable gas is detected based on the signal from the gas detection means 14, the waste can be dried without producing smoke or odor. can.

The above explanation is based on the case where a magnetron is used as the heating means provided in the waste storage chamber 1, but the same effect can be obtained by using combustion heat, electric heater, electromagnetic induction heating means, etc. as the heating means. be.

Since the waste heating means and conveying air blowing means are stopped by signals from the temperature detection section and gas detection section, waste can be dried without producing smoke or odor, and its practical effects are greatly improved. It's big.
