Description

[Technical field]

[0001] The present invention relates to an organic matter treatment apparatus for treating organic matter such as vegetable residues at low temperatures to carbonize them. [Background technology]

[0002] Conventionally, methods have been considered for processing vegetable waste such as vegetable scraps so that they can be used as fertilizer, but these have been aimed at reducing garbage by processing within the home. Also, for vegetable waste (vegetable scraps) discharged from factories, which are larger than those used in homes, devices have been considered for recycling them as feed or fertilizer in order to reduce the amount of waste.

[0003] For example, Patent Document 1 discloses an organic waste treatment device that efficiently and labor-free fermentes food waste such as vegetable waste, fish waste, and meat waste discharged in large quantities from food factories and fishery processing plants, and recycles it into feed and fertilizer. In addition, for example, Patent Document 2 discloses an organic matter fermentation system that rapidly converts organic matter such as fish bones and vegetable waste into compost or feed.

[0004] However, conventional organic matter treatment devices, such as those shown in Patent Documents 1 and 2, use a method in which the waste is heated to a fairly high temperature, such as 250 to 400 degrees Celsius or around 350 degrees Celsius, and hot air is supplied to reduce the waste and cause it to ferment or compost, which creates the problem of the large size of the devices.

[0005] In reality, in factories that generate large amounts of vegetable scraps (vegetable residue), such as vegetable cutting businesses, the current situation is that they ask industrial waste disposal companies to dispose of the vegetable scraps (vegetable residue) as industrial waste.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 5-138145 [Patent Document 2] Japanese Patent Application Publication No. 6-172072 Summary of the Invention [Problem to be solved by the invention]

[0007] However, there was an issue of high costs involved in disposing of the large amount of vegetable scraps (vegetable residue) generated each day as industrial waste. For vegetable cutting businesses, the current situation is that they are spending a lot of money to dispose of vegetable scraps that would otherwise be thrown away, and what's more, because vegetable scraps are about 90% water, they also have to spend a lot of money to dispose of the water. There was a strong demand to somehow resolve this issue.

[0008] The present invention has been made to solve the above-mentioned problems, and aims to provide an organic matter treatment device that treats and carbonizes organic waste such as vegetable scraps at low temperatures in a reaction tank without disposing of the waste and without combustion. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention provides an organic matter treatment apparatus including at least a reaction tank and a dust collector, the reaction tank being provided with an organic matter inlet, a carbon outlet, and a steam exhaust outlet, and a predetermined reaction accelerator being placed in the reaction tank in advance as an initial charge, the organic matter inlet being an inlet through which organic matter is placed in the reaction tank and is provided in the upper part of the reaction tank, the steam exhaust outlet being provided in a position separate from the organic matter inlet in the upper part of the reaction tank, the organic matter placed in the reaction tank from the organic matter inlet and the predetermined reaction accelerator placed in the reaction tank in advance are stirred in the reaction tank, whereby the organic matter is intramolecularly dehydrated and carbonized, and the carbonized carbon is discharged from the carbon exhaust outlet, and steam generated when the intramolecular dehydration of the organic matter is promoted in the reaction tank is collected by the dust collector connected to the steam exhaust outlet, and is discharged from the steam exhaust outlet. Effect of the Invention

[0010] According to the organic waste treatment device of the present invention, organic waste such as vegetable waste is treated in a reaction tank at a low temperature without combustion, and CO 2 It is possible to reduce the amount of waste by carbonization without generating any harmful substances or generating any harmful substances. Another advantage is that it is possible to reduce the high costs that were previously required to treat the waste as industrial waste. [Brief description of the drawings]

[0011] [Figure 1] FIG. 1 is an explanatory diagram showing an example of an outline of an organic matter treatment apparatus according to a first embodiment of the present invention. [Diagram 2] FIG. 11 is an explanatory diagram showing an example of the outline of an organic matter treatment apparatus according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The present invention relates to an organic matter treatment apparatus for treating organic matter such as vegetable residues at low temperatures to carbonize them. Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0013] Embodiment 1 Fig. 1 is an explanatory diagram showing an example of an outline of an organic matter treatment apparatus in a first embodiment of the present invention. As shown in Fig. 1, the organic matter treatment apparatus 1 includes at least a reaction tank 10 and a cyclone dust collector 18. The reaction tank 10 is provided with an organic matter inlet 11, a carbon outlet 12, and a steam exhaust port 13. The reaction tank 10 is also provided with heating adjustment means such as electric heaters (here, a halogen heater 15 and a sheathed heater 16) and an agitator (not shown). Fig. 1 also shows a carbon recovery box 20 that recovers carbon carbonized by the organic matter treatment apparatus 1.

[0014] The organic matter inlet 11 is an inlet through which organic matter (plant residue) such as vegetable waste is introduced into the reaction tank 10, and the organic matter (plant residue) such as vegetable waste is introduced into the reaction tank 10 from here. Generally, the organic matter inlet 11 is provided in the upper part of the reaction tank 10. A predetermined reaction accelerator (e.g., activated carbon) is placed in the reaction tank 10 in advance as an initial charge, and this reaction accelerator is mixed with organic matter (plant residue) such as vegetable waste that is charged from an organic matter inlet 11. As a result, the reaction accelerator promotes the intramolecular dehydration of the organic matter (plant residue) such as vegetable waste, turning the organic matter into carbon, which is then discharged from a carbon outlet 12.

[0015] The carbon outlet 12 is an outlet through which a reaction accelerator and organic matter (plant residue) such as vegetable waste are stirred and dehydrated inside the reaction tank 10, and a carbonized charcoal is discharged. That is, organic matter (plant residue) such as vegetable waste fed from the organic matter feed port 11 and a predetermined reaction accelerator preliminarily placed in the reaction tank 10 are stirred inside the reaction tank 10, so that the reaction accelerator promotes intramolecular dehydration of the organic matter (plant residue), and the organic matter is intramolecularly dehydrated and carbonized, and the carbonized carbon is discharged from the carbon outlet 12. Then, the discharged charcoal (carbon) is collected in a carbon collection box 20. In general, the carbon outlet 12 is provided at one location on the bottom of the reaction tank 10, and a conveyor (not shown) for conveying the carbonized charcoal (carbon) to the carbon outlet 12 is also provided inside the reaction tank 10.

[0016] On the other hand, in order to promote the intramolecular dehydration of organic matter inside the reaction tank 10, heating adjustment means such as electric heaters (here, a halogen heater 15 on the top and a sheathed heater 16 on the bottom) are installed on the top and bottom of the reaction tank 10, and an agitator is also installed inside, but the agitator is not shown. In this embodiment 1, an electric heater is used as the heating adjustment means for heating, but other heating adjustment means may be used, such as using waste heat from a combustion device outside the reaction tank, as long as it can increase the temperature inside the reaction tank and adjust the temperature inside the reaction tank to a low temperature without combustion.

[0017] The temperature inside the reaction tank 10 is kept at a low temperature of 150° C. or less (actually, about 120° C.) by using a heating control means such as an electric heater (halogen heater 15 or sheath heater 16). By stirring at a low temperature of 150° C. or less in this way, a large amount of steam is generated and fills the inside of the reaction tank 10, so a steam exhaust port 13 for discharging the steam is provided at a position separate from the organic matter inlet 11 at the top of the reaction tank 10.

[0018] However, when steam is exhausted, fine particles are exhausted together with the steam in the air flow, so that the carbonized fine particles fall and remain. Therefore, a cyclone dust collector 18 is attached after the steam exhaust port 13, that is, connected to the steam exhaust port 13 outside the reaction tank 10. The carbonized charcoal is separated into solid and gas by centrifugal force and collected by the cyclone dust collector 18. In this way, the charcoal carbonized by the cyclone dust collector 18 is also collected in the carbon recovery box 20. In this embodiment 1, a cyclone dust collector using centrifugal force is used as a dust collector for collecting dust, but other dust collectors such as a HEPA filter may be used as long as they can separate solid and gas by centrifugal force or a high-performance filter to collect dust.

[0019] In other words, this organic matter treatment device 1 is a device that keeps the temperature inside the reaction tank 10 containing organic matter (plant residues) such as vegetable waste at a low temperature of below 150 degrees Celsius, and promotes intramolecular dehydration of the organic matter (plant residues) while stirring the organic matter inside the reaction tank without combustion, enabling the organic matter (plant residues) to be discharged in a carbonized state.

[0020] As described above, according to the organic matter treatment device 1 in the first embodiment of the present invention, carbon can be produced from organic matter (plant residue) such as vegetable waste, and since treatment is carried out at a low temperature in the reaction tank without combustion, CO 2 It is also environmentally friendly, since it generates almost no dust or other harmful substances. In addition, it eliminates the need to dispose of large amounts of organic matter (plant residues) such as vegetable scraps as industrial waste, which saves on the high costs that were previously required for industrial waste disposal.

[0021] Embodiment 2 FIG. 2 is an explanatory diagram showing an example of an outline of an organic matter treatment device in the second embodiment of the present invention. As shown in FIG. 2, the organic matter treatment device 2 includes at least a reaction tank 10, a cyclone dust collector 18, and a neutralization scrubber 19, and the reaction tank 10 is provided with an organic matter inlet 11, a carbon outlet 12, and a steam exhaust port 13. That is, compared with the organic matter treatment device 1 shown in FIG. 1 in the first embodiment, a neutralization scrubber 19 is further added. Also, like the organic matter treatment device 1 in the first embodiment, the reaction tank 10 is provided with heating adjustment means such as electric heaters (here, a halogen heater 15 and a sheathed heater 16) and an agitator (not shown) inside. Note that FIG. 2 also shows a carbon recovery box 20 that recovers carbon carbonized by the organic matter treatment device 2, and a wastewater recovery tank 30 after the discharged steam is treated.

[0022] Here, the same reference numerals are used to designate the same components as those described in the first embodiment, and the repeated explanations will be omitted. Therefore, the explanations of the reaction tank 10, the organic matter inlet 11, the carbon outlet 12, the steam outlet 13, etc. are the same as those described in the first embodiment, and therefore detailed explanations will be omitted here.

[0023] When steam is discharged, fine particles are entrained in the airflow and discharged together with the steam, so that the carbonized fine particles fall and remain, a cyclone dust collector 18 is attached behind the steam exhaust port 13, that is, connected to the steam exhaust port 13 outside the reaction tank 10, the carbonized charcoal is separated into solid and gas by centrifugal force by the cyclone dust collector 18, and the charcoal carbonized by the cyclone dust collector 18 is also collected in a carbon recovery box 20, which is the same as in the organic matter treatment device 1 in the first embodiment. Note that the dust collector is not limited to a cyclone dust collector, as long as it is a dust collector that can collect dust by centrifugal force or a high-performance filter, which is the same as in the first embodiment.

[0024] In this second embodiment, since the pH of organic matter (plant residues) such as vegetable waste is acidic (less than 7.0), and if the acidic steam and exhaust gas are simply discharged, environmental problems may arise. Therefore, a neutralization scrubber 19 is newly provided to further neutralize the steam by alkaline treatment before discharging it.

[0025] In other words, the steam generated when intramolecular dehydration of organic matter (plant residues) is promoted inside the reaction tank 10 is collected by the cyclone dust collector 18 connected to the steam exhaust port 13 and discharged from the steam exhaust port 13, and the steam discharged from the steam exhaust port 13 and collected by the cyclone dust collector 18 is further treated with alkali by the neutralization scrubber 19 and neutralized (neutralization treatment is performed).

[0026] The neutralizing scrubber 19 is equipped with an adjustment section (not shown) that performs the roles of neutralization and deodorization, and because the steam discharged from the steam exhaust port 13 is still acidic after it has turned into water, it performs a neutralization process in which the acidic water is alkali-treated to neutralize it to a pH of about 6 to 8, so that it can be discharged in a state that meets environmental standards. The wastewater (sewage) neutralized in this neutralizing scrubber 19 is collected in the wastewater collection tank 30, but because this is wastewater that has already been neutralized to a nearly neutral pH, there are no environmental problems with subsequent treatment.

[0027] In other words, this organic matter treatment device 2 is a device that keeps the temperature inside the reaction tank 10 containing organic matter (plant residues) such as vegetable scraps at a low temperature of below 150 degrees Celsius, and promotes intramolecular dehydration of the organic matter (plant residues) while stirring the organic matter (plant residues) inside the reaction tank without combustion, carbonizing the organic matter (plant residues), and also neutralizes the discharged steam to a neutral pH of about 6 to 8, allowing it to be discharged in a state that meets a certain level of environmental standards.

[0028] As described above, according to the organic matter treatment device 2 in the second embodiment of the present invention, carbon can be produced from organic matter (plant residue) such as vegetable waste, and since treatment is performed at a low temperature in the reaction tank without combustion, CO 2 This has the effect of being environmentally friendly, since almost no dust or other harmful substances are generated, and the steam discharged from the reaction tank 10 is neutralized before being discharged. In addition, there is no need to dispose of large amounts of organic matter (plant residues) such as vegetable waste as industrial waste, which has the advantage of saving the high costs that were previously required for processing such waste.

[0029] It should be noted that within the scope of the present invention, the embodiments may be freely combined, any component of each embodiment may be modified, or any component of each embodiment may be omitted. [Explanation of symbols]
