The present invention also relates to an apparatus for treating organic wastes using the dry carbonation process.

Due to the development of the industrial society, the amount of organic wastes that are difficult to process due to various odors generated due to the large amount of various organic matters as well as municipal wastes (such as food wastes, wastes from food processing factories, excretions excreted by various animals, etc.) Is gradually increasing. In addition, various organic wastes such as industrial wastes and organic wastes generated from organic sludge, housing, etc. in various industrial sites are highly perishable and difficult to be stored for a long time, If it is discharged as it is, it will pollute soil and river and cause various environmental problems and social problems.

In the case of Korea, marine emissions of municipal solid waste and various sludge that have been partially allowed for the period have to be completely stopped from January 1, 2016 and the land should be disposed of. In particular, the number of domestic public sewage treatment plants is increasing, sewage treatment is eutrophication The amount of sewage sludge has been steadily increasing with the addition of sophisticated processes to remove phosphorus and nitrogen, the causative substances.

 Despite being an energy poor country, waste of resources is becoming a serious problem because 56% of waste that can be recovered from energy is included among the wastes treated by landfill or simple incineration. As a result, the government has promulgated the Law on Recycling of Resources on May 29, 2016 and will be implemented on January 1, 2018. In the case of permanent disposal of useful resources by simple incineration or landfill under this Act, the costs equivalent to recycling costs shall be paid as waste disposal fees.

In addition, the government must replace 10% of the total consumption by renewable energy by 2023 by the RPS, which requires the use of some of the total fuel as renewable fuel.

There has been a need for a method of responding to government policies, preventing environmental pollution, and treating various wastes in an environmentally friendly way. There are many methods for treating organic wastes, and many studies have been made.

Typical treatment methods include composting, solidification, incineration, dry fuel conversion, and carbonization. Among them, carbonization method has been recognized as superior to other methods in terms of environmental performance, functionality, and civil sensitivity, but it has been evaluated to be somewhat difficult in comparison with other methods in terms of economy and utilization of byproducts. In other words, the carbonization method requires a lot of facilities such as heat exchange facilities for lowering the processing efficiency by increasing the heat efficiency, equipment for removing odor and various harmful gases generated, and thus the facility cost (about 250 million KRW / ton) And it has a disadvantage that it occupies a lot of sites for installation and operation.

Therefore, it is necessary to develop an organic waste treatment device which can be used as auxiliary fuel by reducing the carbonization temperature and saving the fuel cost to be consumed, and by heating the by-product generated in the carbonization process, to be.

Referring to FIG. 1, the apparatus for treating organic wastes using the dry carbonation method of the present invention has an outer case 10 in which a receiving space is formed. A combustion air inlet 11 is formed at one side of the outer case so that the air required for combustion in operation of the heating unit 300, which will be described later, can be introduced into the outer case 10.

The sludge supply unit 100 includes a sludge supply unit 100 for supplying the organic waste to the dryer 200 disposed in the receiving space of the outer case 10, .

At this time, the dryer 200 maintains a shape extending in one direction and has a hollow shape to receive the organic waste from the sludge feeder 100. At this time, the transferred organic waste is dried while moving the inside of the hollow dryer 200 from one side to the other side.

The heating unit 300 heats the outer surface of the dryer 200 to supply thermal energy. That is, the outside of the dryer 200 is heated, and LPG or LNG is supplied from the outside to be used as fuel. That is, since the heating unit 300 heats the dryer 200, the internal temperature of the dryer 200 rises and the moving organic wastes are dried simultaneously.

Referring to FIG. 1, a carbonizer 400 is connected to the dryer 200 to receive dried organic waste. The carbonizer 400 is preferably located in the outer case 10, and the organic waste contained therein is carbonized or semi-carbonized to be discharged to the outside. At this time, the carbonized or semi-carbide pyrolyzed in the carbonizer 400 is moved to and stored in a separate carbonaceous reservoir 500.

A heating unit 700 for heating the outside of the carbonizer 400 to pyrolyze the organic waste contained in the carbonizer 400 is further provided. The heating unit 700 is located at the lower end of the carbonizer 400 and supplies thermal energy to the carbonizer 400 when the waste heat discharged from the outer case 10 does not supply sufficient heat for carbonization or half- .

Referring to FIGS. 1 and 2, the remaining waste heat that is heated when the heating units 300 and 700 heat the dryer 200 and the carbonizer 400 is moved to the upper side of the outer case 10. At this time, the waste heat moved to the upper side of the outer case 10 is re-supplied to the dryer 200 or the carbonizer 400 according to the user's selection, thereby minimizing the waste of energy.

Referring to FIGS. 1 and 2, the dryer 200 includes a first drying pipe 210 and a second drying pipe 220. The first drying pipe 210 receives the organic waste from the sludge feeder 100 and primarily dries the organic waste. At this time, the first drying pipe 210 maintains a hollow shape inside to receive the transferred organic waste. The organic waste contained in the first drying pipe 210 is agitated and dried while moving along the first drying pipe 210.

The second drying pipe 220 is spaced apart from the first drying pipe 210 and is formed so as to surround the outside of the first drying pipe 210. The second drying pipe 220 moves along the first drying pipe 210, The organic waste is received and dried secondarily. The dried organic wastes are then transferred to the carbonizer 400. It is preferable that the distance between the first drying pipe 210 and the second drying pipe 220 is 50 mm or less. This prevents the organic wastes moving in the second drying pipe 220 from being constrained to move together It is for this reason. The organic waste contained in the second drying pipe 220 is also stirred and dried while moving along the second drying pipe 220.

Referring to FIG. 1, the dust collecting unit 600 receives moisture and dust generated in the first and second drying tubes 210 and 220. When the organic waste is dried in the dryer (200), the dust collecting unit (600) treats dust (fine dust) generated by evaporation of moisture and moisture contained in the organic waste. That is, when the air containing dust and dust are moved from the dryer 200 to the dust collection unit 600, the dust collection unit 600 separates the air containing dust and moisture and discharges the separated dust to the carbide storage 500 And odorous substances including water are discharged to the outside through a separate process.

The air discharged from the dust collecting unit 600 is preferably discharged to the atmosphere through a regenerative thermal oxidizer (RTO) corresponding to a thermal oxidizer or a scrubber and a separate filter before releasing the air to the atmosphere.

Referring to FIG. 4, the first drying pipe 210 includes a first drying case 211, a hollow shaft 212, and a second blade 213. The first drying case 211 has a hollow shape so as to receive organic waste therein and is formed to extend to one side.

The hollow shaft 212 is located inside the first drying case 211 and can be rotated by external power. The hollow shaft 212 maintains a hollow shape and is formed with a hot air jet opening 212-1 communicating with the hollow interior while being spaced apart from each other by a predetermined distance.

The first blade 213 is spaced apart from the outer surface of the hollow shaft 212 and is fixed in a spiral shape. That is, the first blades 213 and the hollow shaft 212 are connected by a plurality of connection rods 213-1 spaced apart from each other by a predetermined distance. Depending on the length of the connection rods 213-1, The spacing between the hollow shaft 213 and the hollow shaft 212 can be adjusted. Accordingly, as the hollow shaft 212 rotates, the first blade 213 also rotates, and at the same time, the organic waste can be agitated in the first drying case 211.

The second drying tube 220 includes a second drying case 221 and a second blade 222. The second drying case 221 maintains a hollow shape in order to receive the organic waste discharged from the first drying case 211.

The second blade 222 is attached to the outer surface of the first drying case 211 and maintains the same spiral shape as the first blade 213. When the first drying case 211 rotates by external power, the second blade 222 stirs the organic waste in the second drying case 221.

A plurality of flow grooves 222-1 spaced along the outer edge are formed in the second blade 222 to prevent agglomeration of the organic wastes during stirring of the organic wastes and smooth stirring and movement of the organic wastes do.

1, when the waste heat supplied from the outer case 10 to the carbonizer 400 is supplied again to the carbonizer 400, the waste heat is transferred to the interior of the carbonizer 400 to heat the carbonator 400 do. The waste heat discharged to the carbonizer 400 after the carbonizer 400 is heated is supplied to the dryer 200 and can be directly contacted with the organic waste to be dried to further enhance the drying efficiency.

The waste heat discharged to the carbonizer 400 after the drying machine 200 and the carbonizer 400 are heated can be moved to the dust collector 600 and processed.

Referring to FIGS. 1 to 3 and 5, the carbonizer 400 includes a hot air case 410, an induction blade 420, a carbonization case 430, and a stirring blade 440. The hot air blower case 410 is hollow and receives the residual heat from the outer case 10, and the hot air blower case 410 is heated to a predetermined temperature. When the waste heat is supplied, it can be delivered by hot air including heat energy through a separate blower.

The induction blade 420 is mounted in the hollow interior of the hot air case 410, and the incoming waste heat is guided to the induction blade 420. Thus, the time during which waste heat stagnates in the hot air case 410 is increased to improve the heating efficiency of the hot air case 410.

The carbonization case 430 is provided on the outer side of the hot air case 410 so as to be spaced apart from the hot air case 410 by a predetermined distance. The carbonized case 430 receives the dried organic waste from the dryer 200 and is carbonized or semi-carbonated by the heated heat source of the hot air case 410 as the transferred organic waste moves.

At this time, the stirring blade 440 is formed along the inside of the carbonization case 430. The agitating blade 440 also has a spiral shape, and the transferred organic wastes are agitated to increase the degree of carbonization of the organic waste. The stirring blade 440 is provided with a number of agitating grooves 440-1 spaced apart along the outer edge of the agitating blade 440 for smooth agitation of the organic waste and smooth discharge of the generated dry gas during agitation of the organic waste, .

Referring to FIGS. 1 and 5, waste heat discharged after heating the hot air case 410 is transferred to the hollow shaft 212 of the dryer 200. At this time, when the hot air is injected into the hot air ejection port 212-1, the organic waste contained in the first drying case 211 and the hot air are mixed with each other, and the drying time and drying efficiency of the organic waste can be shortened.

Referring to FIG. 1, the carbonization case 430 further includes a temperature sensor 432 for measuring the temperature inside the carbonization case 430.

That is, in order to reuse the carbonated or semi-carbonized by-product in the carbonizer 400 as a fuel, the dried product of the organic waste must be semi-carbonated. In order to achieve half-carbonization, the temperature inside the carbonized case 430 is about 300 ° C. You must keep it. When the temperature inside the carbonization casing 430 is high according to the temperature value measured by the temperature sensor 432 in order to maintain the temperature when the waste heat is supplied to the carbonizer 400 from the outer case 10, , And to be able to re-supply the waste heat to the dryer (200).

If the use of by-products is not used as auxiliary fuel, it is necessary to fully utilize the carbon monoxide generated by completely carbonizing the organic waste. In this case, the heat supplied from the outer case 10 may be insufficient. At this time, the heating unit 700 is operated to supply sufficient heat to the carbonator 400.

Accordingly, it is possible to control the opening and closing of the induction pipe 900 and the induction pipe 900, one side of which is connected to the supply line for supplying waste heat to the carbonizer 400, and the other side of which is connected to the dryer 200 An additional valve 431-1 should be installed. Thus, the temperature inside the carbonizer 400 is maintained at a user-set temperature value so as to control the carbonization rate of the organic waste depending on whether the heating unit 700 is turned on / off and the valve 431-1 is opened or closed .

In addition, the pressure of the dry cargo gas is increased by the carbon monoxide gas during the (semi) carbonization of the waste product in the carbonizer 400. At this time, due to the elevated pressure, the dry gas is discharged to the outside of the carbonizer, and the odor is volatilized inside the factory, which makes it difficult to work and there is a risk of fire due to the dry gas. In order to prevent this, a pressure sensor is preferably installed so that the carbon dioxide gas can be discharged to the outside of the carbonizer by using a blower so that the pressure of the carbon dioxide gas does not exceed a predetermined pressure.

Another embodiment of the dryer 200 will be described with reference to FIG. The dryer 200 includes a first drying pipe 210 for receiving organic waste from the sludge feeder 100 and drying the first organic waste material and a first drying pipe 210, And a second drying pipe 220 for receiving and drying the dried organic waste.

The oxidation pipe 230 surrounds the outside of the second drying pipe 220. The oxidizing pipe 230 is connected to the first drying pipe 210 and the second drying pipe 220 by moisture, Bad smell, and so on. Since the oxidation pipe 230 is located outside the second drying pipe 220, the heating unit 300 heats the outer surface of the oxidation pipe 230. Therefore, odor and various noxious gases stored in the oxidation pipe 230 due to heat energy transmitted from the heating unit 300 are thermally decomposed and removed. The heated air, which has been received in the oxidation pipe 230 and has been pyrolyzed, is transferred to the carbonizer 400 to heat the carbonator 400.

Referring to FIGS. 1 and 3, a purifier 1000 connected to the carbonizer 400 is further provided. The purifier 1000 receives the carbon monoxide generated from carbonization of the organic waste from the carbonizer 400 and removes the harmful substances contained in the carbon monoxide gas.

This carbonized gas cleaner is described in Korean Patent No. 10-1521259 entitled " Waste Pyrolysis Apparatus Using Waste Heat. &Quot;

The first heat exchanger 1100 receives the dry gas from which the tar and the like have been removed from the dry gas cleaner 1400. At this time, the temperature of the high temperature gas is lowered as the gas is contacted with the refrigerant pipe provided inside. At the same time, the dry gas and the refrigerant pipe come into contact with each other, moisture is formed in the refrigerant pipe, and the harmful substances contained in the moisture and the dry gas are collected at the lower end of the first heat exchanger 1100.

The second heat exchanger (1200) receives the dry gas from the first heat exchanger (1100) and purifies the harmful substances contained in the dry gas by second order. Since the refrigerant pipe is also provided in the second heat exchanger 1200, the harmful substances of the gasses are purified in the same manner as the first heat exchanger 1100.

The pressure regulating tank 1300 has the purpose of compensating for the pressure due to the altered temperature of the dry gas when the dry gas passes through the first and second heat exchangers 1100 and 1200. The purified gas is then sent to the heating unit 300 or the thermal oxidizer (RTO) to be processed.
