The present invention is a process for recycling the waste through the fermentation tank, the dryer and the carbonizer using organic waste as a raw material, the dryer is composed of a kiln dryer and a paddle dryer, the dryer exhaust gas discharged from the kiln dryer is provided to a heat exchanger Carbide exhaust gas discharged from the carbonizer is provided to the burner portion of the kiln dryer to recycle, pass through the carbonizer through the kiln dryer to produce carbonized fuel, and pass through the paddle dryer to produce fertilizer. The present invention relates to a recycling method of organic waste recycled from waste heat, characterized in that the carbonized fuel and fertilizer are produced at the same time.

The present invention is characterized in that the use of a kiln dryer and a paddle dryer can selectively or simultaneously produce charcoal, a fertilizer and carbonized fuel.

1 shows a schematic diagram of an organic waste recycling process according to an embodiment of the present invention.

The organic waste recycling treatment process according to an embodiment of the present invention selectively or simultaneously manufactures charcoal and fertilizer using a fermentation tank, a kiln dryer, a paddle dryer, and a carbonization machine, and recycles the exhaust gas emitted from the kiln dryer and the carbonization machine.

Referring to Figure 1, the organic waste in the fermenter can be moved to a kiln dryer or paddle dryer, in which the organic waste can be moved to a paddle dryer or carbonizer, the paddle dryer can be moved to a carbonizer or to produce fertilizer The process takes place. The material from the carbonizer can produce charcoal, the fuel of carbonization. In the kiln dryer, the waste heat of the dryer exhaust gas is discharged, and the kiln dryer can be recycled to the heat exchanger. In addition, the carbonized carbon waste gas is discharged from the carbonizer, which can be transferred to a kiln dryer or paddle dryer to recycle hot dried exhaust gas to dry organic waste.

The organic waste may use livestock manure and livestock wastewater such as pig manure and manure, and may use this to produce fertilizers and carbonized fuels.

Looking at the organic waste recycling process according to the present invention when the organic waste is supplied to the fermenter through a mixer, the fermentation takes place for a certain time. The fermentation time may vary depending on the type of organic waste to be supplied. Generally, fermentation is performed for 7 days to 10 days.

In the fermentation tank, one or more types of organic waste may be mixed with coco peat, rice hulls and palm leaves. This can enhance the fuel efficiency and nutrition of the char and fertilizer produced.

The organic waste introduced into the treatment process of the present invention may have various water contents according to the type and condition of the waste to be supplied. The water content of organic waste is at least about 40% and can be as high as 90% or more. Therefore, the moisture content of the organic waste can be detected to control the type and drying time of the dryer.

As the dryer used in the present invention, a kiln dryer and a paddle dryer may be used. The organic waste raw material from the kiln dryer and the paddle dryer may be directly manufactured as a fertilizer or a carbonized fuel through carbonization. .

Organic waste may be transferred from the fermentor to the dryer, which may be transferred to a kiln dryer or paddle dryer. Organic waste entering the paddle dryer through the fermentation tank can produce fertilizer, and organic waste entering the kiln dryer through the fermentation tank can optionally produce fertilizer.

The kiln dryer according to the present invention has an excellent drying efficiency and a higher capacity than the paddle dryer, thereby treating a large amount of organic waste and having an excellent water removal rate. However, the kiln dryer has a disadvantage that the product cost is more expensive than the paddle dryer and takes up a lot of installation space.

Figure 2 shows a cross-sectional view of the kiln dryer used in the present invention.

Looking at the structure of the kiln dryer, a burner part 11 for applying heat, two chambers 12, a roller part 13, an exhaust pipe 14 through which gas can be exhausted, an inlet port 15, an outlet port 16, and It consists of an air inlet (17).

The burner part 11 applies heat from the outside to transmit the hot air in the chamber 12 to dry it. At this time, the organic waste in the kiln dryer is dried by hot air provided by the burner unit 11. As the heat is supplied from the burner part 11 and the air is introduced through the air inlet 17 from the outside, the burner part 11 helps to ignite and dry well.

In addition, the air inlet 17 may recycle the hot dry exhaust gas generated from the carbonizer to be introduced into the air inlet 17, and may help to supply heat from the burner unit 11 by using the same. .

On the other hand, as the organic waste is dried, the exhaust gas is generated in the kiln dryer, and the exhaust gas has high temperature steam due to the moisture contained in the organic waste. Therefore, the exhaust gas emitted from the kiln dryer has a large heat capacity. By using this, it can be used for various purposes in heat exchanger. That is, the dryer exhaust gas having a large heat capacity can be heated in a heat exchanger to make hot water, and the hot water can be used for other purposes. The steam mixed in the exhaust gas is liquefied into hot condensate in the heat exchanger. In addition, the liquefied high-temperature condensate can also be recycled, it can be mixed with the fermenter to increase the temperature of the fermenter.

In addition, exhaust gas may be formed in the carbonizer, and the gas generated in the carbonizer is characterized by high temperature drying. Such exhaust gases from the carbonizer can be recycled back to the kiln dryer and / or paddle dryer. That is, the carbonized exhaust gas may be supplied to the burner part of the kiln dryer through the air inlet 17 to help dry the organic waste in the dryer together with the hot air provided by the burner part.

The carbonizer exhaust gas may also be supplied to the paddle dryer to help dry the organic waste that is dried in the paddle dryer.

Figure 3 shows a cross-sectional view of the paddle dryer used in the present invention.

The paddle dryer utilizes heat supplied in the dryer for most of the heat to be dried, and thus has an advantage of low installation area, simple installation, and high thermal efficiency. Looking at the structure of the paddle dryer used in the present invention, organic waste inlet, shaft 21, single screw 22, exhaust port 23 for exhausting the gas inside, organic waste outlet and exhaust gas inlet 24 Etc. The exhaust gas inlet 24 serves as an inlet for introducing the exhaust gas generated from the carbonizer, and recycles the high temperature dried carbon dioxide exhaust gas into the paddle dryer to assist drying. The exhaust gas inlet 24 may be formed in parallel in the longitudinal direction.

Figure 4 shows a schematic view of the shaft and the single screw in the paddle dryer used in the present invention.

In addition, in the paddle dryer, the shaft 21 has an air supply portion at the position where the individual screw 22 is located, so that air is supplied to the individual screw 22 portion when the shaft is rotated, so that organic waste is stored in the paddle dryer. When mixing, it can be better mixed.

The kiln dryer and paddle dryer may be suitably used in the manufacture of fertilizer and charcoal due to the characteristics of each dryer, and accordingly, the production rate to be manufactured may be appropriately adjusted. That is, in the case of preparing only charcoal or in order to manufacture only fertilizer, the production rate of charcoal or fertilizer may be controlled by controlling the transfer of the fermenter to the dryer.

In addition, when the organic waste is supplied from the fermenter to the kiln dryer or paddle dryer, it may be classified according to the water content of the waste. That is, the moisture content measuring means may be additionally installed between the fermenter and the dryer. The organic waste water content of which is less than 50% is supplied to the paddle dryer, and the organic waste water content of 50% or more is supplied to the kiln dryer by the moisture content measuring means. Can be. The organic wastes fed to the kiln and paddle dryers produce charcoal or fertilizer by subsequent process procedures.

In the kiln dryer and paddle dryer, char or fertilizer can be produced according to the route of the organic waste, which can be connected to a carbonization machine, through which the carbonized fuel can produce charcoal, and also kiln The dryer may be connected to a paddle dryer, and the paddle dryer may be connected to a carbonizer to produce charcoal through a kiln dryer, a paddle dryer, and a carbonizer. Organic waste from the paddle dryer can be produced directly from fertilizers without being transported to the carbonizer.

At the same time, the dryer exhaust gas from the kiln dryer and the carbonizer exhaust gas from the carbonizer can be recycled and used in the treatment process itself or to make hot water.

In order to improve productivity efficiency, the present invention may not properly manufacture all materials passed through the dryer using only fertilizer or only charcoal, but may properly adjust the treatment process according to the needs of the material (charcoal or fertilizer) to be manufactured. At the same time, the dryer exhaust gas from the kiln dryer and the carbonizer exhaust gas from the carbonizer can be recycled and used in the treatment process itself or to make hot water.

That is, the charcoal may be manufactured by transferring the material entering the paddle dryer through the fermentation tank and the kiln dryer to a carbonizer, rather than all of the materials passing through the paddle dryer. In addition, instead of producing charcoal for all materials passing through the kiln dryer, some of the moisture contained in the organic waste may be removed from the kiln dryer and fertilizer may be manufactured through a paddle dryer.

More specifically look at the process of manufacturing charcoal and fertilizers and the exhaust gas discharged.

First, the process of manufacturing charcoal is as follows.

In order to manufacture charcoal, the organic waste is supplied from the fermentation tank to the kiln dryer, and may be arbitrarily supplied as necessary, or organic waste having a high moisture content may be supplied by a moisture content measuring means. If supplied by moisture content measuring means, organic waste with a moisture content of 50% or more is transferred to a kiln dryer.

In the kiln dryer, organic wastes are dried to remove moisture, and the dryer exhaust gas generated during the drying process is transferred to a heat exchanger to produce hot water. In addition, the dryer exhaust gas in the process of producing hot water and the like is characterized by high temperature and high humidity to liquefy to high temperature condensate. The high temperature condensed water liquefied may be mixed with the fermenter and recycled by increasing the temperature of the fermenter.

Organic waste from the kiln dryer is transferred to the carbonizer.

In addition, when the charcoal is prepared using a large amount of organic waste, if the kiln dryer is manufactured using only a kiln dryer, there is a problem in that the productivity is lowered. That is, when charcoal is manufactured using organic waste having high moisture content, it is difficult to process all the materials in the kiln dryer or to remove productivity from the kiln dryer and then move to the paddle dryer to improve productivity. Organic waste material transferred to the paddle dryer has a water content of about 20 to 40%.

After treatment to remove moisture through the paddle dryer, which is moved through the kiln dryer, the organic waste is transferred to the carbonizer with a water content of less than 10%. The dryer exhaust gas generated in the kiln dryer is used to prepare hot water and the like as described above, and the hot condensed water liquefied during the hot water manufacturing process is introduced into the fermenter.

The material transferred to the carbonizer through the kiln dryer and paddle dryer is carbonized to charcoal as a fuel with a water content of 0.01 to 5%.

The carbonized fuel produces charcoal in the form of powdered coal, and hot carbonized carbon exhaust gas is generated in the carbonization process in the process of producing the charcoal. The carbonizer exhaust gas is fed to the kiln dryer due to its high temperature drying properties to help dry organic waste in the dryer.

Figure 5 shows a cross-sectional view of the carbonizer used in the present invention.

The carbonizer is formed in a cylindrical shape, there is a conveying screw formed long in the carbonization machine, and has a plurality of wings 37 on the outer circumferential surface of the conveying screw.

A plurality of wings 37 are attached to the outer circumferential surface of the transfer screw, each of the wings 37 are arranged spaced apart at a predetermined angle, for example about 45 degrees with respect to the transfer screw. Accordingly, the material moved in the carbonizer simultaneously moves and agitates.

The carbonized material is introduced into the upstream end of the first carbonizer 31, the material is conveyed while stirring by the first transfer screw 34, is heated to about 400 ℃ by the thermal band 33 during the transfer To dry.

In addition, the material transferred to the downstream end of the first carbonization machine 31 by the first transfer screw 34 is heated and burned to about 400 ° C., and the second carbonization is carried out through the outlet part 35 in the burned state. To the machine 32. The dried material introduced into the second carbonizer 32 is transferred by the second transfer screw 36 to the downstream end of the second carbonizer 32.

The dried material conveyed to the downstream end of the second carbonizer 32 while being agitated by the second conveying screw 36 is continuously heated and burned, for example, by 350 to 400 ° C. by the heat band 33 while being conveyed, The dry exhaust gas generated at this time is exhausted through the exhaust pipe 41 and recycled.

The inside of the carbonizer is carbonized in a state in which it is blocked from the outside so that external air does not flow in, and the carbonizer may be positioned at upper and lower ends of the first and second carbonizers. Since it occupies a lot of space when connected in the longitudinal direction, it is positioned up and down to utilize the width direction, and the heat supply can be different.

The outside of the carbonizer is provided with a heat band 33 for heat supply to supply heat to the carbonizer. The temperature of the heat supplied to the heat band 33 is supplied at about 500 ~ 700 ℃, and is maintained at about 400 ℃ or more in the carbonizer.

The first carbonizer 31 located at the upper end of the carbonizer allows the carbonization to occur intensively with a large amount of heat supply, and the second carbonizer 32 located at the lower end moves the heat band 33 to the vicinity of the middle of the second carbonizer. It is formed only to reduce the heat supply than the first carbonizer 31. The reason for reducing the heat supply to the second carbonizer 32 located at the bottom is that due to the heat supplied from the first carbonizer 31, combustion occurs in the second carbonizer 32 itself, so that the second carbonizer 32 Has the effect of being carbonized with less heat.

In addition, the exhaust gas generated in the first carbonizer 31 and the second carbonizer 32 is characterized by high temperature drying, which may be supplied to the kiln dryer or paddle dryer through the exhaust pipe 41 and recycled. .

Meanwhile, the carbonized material conveyed to the downstream end of the second carbonizer 32 by the second conveying screw 36 is discharged onto the conveying means 38 through the outlet part 35 ', and the conveying means 38 The material discharged on the upper side is conveyed by the conveying means 38, and can be sufficiently cooled during the conveying.

At the lower end of the second carbonizer 32, it is possible to cool the carbonized fuel in the transfer means 38. This means that when the carbonized material at high temperature comes into direct contact with external air, combustion occurs and becomes ash. To prevent it. The transfer means 38 has a screw 39 to move the material by rotating the screw 39, it is possible to manufacture the charcoal, the carbonized fuel using the moved material.

The charcoal is manufactured in the form of powdered coal, and afterwards, a solidified fuel (RDF) may be manufactured through a molding process.

Next, look at the process of manufacturing the fertilizer as follows.

The organic wastes supplied through the fermenter may be introduced into the paddle dryer voluntarily or in the paddle dryer when the moisture content is 50% or less by means of the moisture content measuring means, and fertilizer may be prepared based on this.

That is, fertilizers can be prepared by moving the fermenter to a paddle dryer and adjusting the water content in the paddle dryer to about 10 to 40%. In the case of producing the charcoal and fertilizer at the same time it can help the drying in the paddle dryer by supplying the carbon dioxide exhaust gas discharged through the carbonizer to the paddle dryer. That is, the carbon dioxide exhaust gas, which is the waste heat of the carbonizer, may help to remove moisture of the organic waste in the paddle dryer due to the high temperature and dry characteristics.

Organic waste may also be produced through the kiln dryer and paddle dryer, where organic waste entering the kiln dryer through the fermentation tank is removed to some extent and then transferred to the paddle dryer. At this time, the material discharged through the kiln dryer is discharged with a water content of 50% or less. In such a process, the exhaust gas discharged may be recycled, and the dryer exhaust gas generated in the kiln dryer is used to prepare hot water by moving to a heat exchanger, and the dryer exhaust gas is liquefied with high temperature condensed water. Condensate can be mixed into the fermenter and recycled by increasing the temperature of the fermenter.

The material moved to the paddle dryer through the kiln dryer can be removed to further remove moisture to produce a fertilizer to 10 to 40% water content.

As described above, the present invention may selectively or simultaneously produce charcoal and fertilizer through a kiln dryer and a paddle dryer.

Looking at the treatment process in the case where only charcoal is to be prepared, organic waste is transferred to the kiln dryer when moving from the fermenter to the dryer. Moisture is removed by moving to a kiln dryer so that the moisture content is 10% or less, and then moved to a carbonized carbon to produce charcoal. In addition, paddle dryers can be used to increase the productivity of charcoal.The amount of organic waste transferred from the fermentation tank to the kiln dryer does not allow water content to be less than 10% and removes only a portion of the moisture. Move it. Organic waste that has been transferred to a paddle dryer can be transferred to a carbonizer after additional moisture removal. At this time, the water content of the material that is transferred from the paddle dryer to the carbonizer is 10% or less. In this case, the carbon exhaust gas generated from the carbonizer may be supplied to the kiln dryer and / or the paddle dryer to recycle waste heat.

Meanwhile, in the case of manufacturing only fertilizers, fertilizers can be directly moved to a paddle dryer in a fermenter to prepare fertilizers, or after removing some water through a kiln dryer, the fertilizer can be manufactured to have a water content of 10 to 40% in a paddle dryer. .

In addition, in the case of manufacturing the charcoal and fertilizer at the same time it is possible to adjust the ratio of the charcoal and fertilizer.

For example, after moving organic waste from the fermenter to the kiln dryer alone, some of the organic waste is transferred to the paddle dryer, where the remaining material is removed to a water content of less than 10% and transferred to the carbonizer. The fertilizer can be prepared by transferring the material to the paddle dryer to a water content of 40% or less.

In another method, the material transferred to the kiln dryer and paddle dryer in the fermenter at a constant rate removes water at a moisture content of 10% or less, moves to a carbonizer to produce charcoal, and transfers to the paddle dryer. The fertilizer can be prepared by removing moisture with a water content of 40% or less.

If you want to manufacture a large proportion of charcoal in another method, because a large amount of organic waste must be transferred to the kiln dryer, after moving to the kiln dryer, some water is removed and then transferred to the paddle dryer. At this time, the organic waste in the fermenter is continuously transferred to the kiln dryer. The organic waste remaining in the kiln dryer is transferred to the carbonizer at a water content of less than 10% to produce charcoal. In addition, some of the materials in the paddle dryer to produce a fertilizer with a water content of 40% or less, and then continue to operate to make a water content of 10% or less and then moved to a carbonizer to produce charcoal at a water content of 0.01 to 5%.

In this manufacturing process, the dryer exhaust gas generated in the kiln dryer produces hot water in a heat exchanger, and during the manufacturing process of hot water, the dryer exhaust gas is liquefied into hot condensed water and mixed into the fermenter to raise the temperature of the fermenter. can do. In addition, the carbon exhaust gas generated in the carbonizer may be re-introduced into the kiln dryer and / or paddle dryer and recycled due to the high temperature and dry characteristics.

The treatment process according to the present invention recycles the generated exhaust gas and has the advantage of selectively producing charcoal or fertilizer as needed or simultaneously manufacturing charcoal and fertilizer using one treatment process.

In the case of charcoal and fertilizer manufactured through the organic waste treatment process of the present invention, the water content is 0.01 to 5% for charcoal, and 10 to 40% for fertilizer.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge of.
