The present invention relates to an apparatus for carbonizing organic waste in multiple stages using indirect heat, and more particularly, to organically treat organic waste more stably and efficiently by indirect heat, thereby preventing environmental pollution, and having a small installation area. The present invention relates to a multi-stage carbonization device for organic waste using indirect heat, which is low in operation cost and can recycle the final by-product.

(General conventional technology)

In general, a device for treating organic wastes containing a lot of moisture, such as sewage sludge and food wastes, and mixed with a moisture control agent and stored in a fermenter and then aerobic fermentation to make a compost; There is a device for drying and carbonizing the organic waste to recycle it into carbides.

Since the present invention relates to a multi-stage carbonization device, the structure and problems of a general carbonization device will be described below.

The first developed organic waste carbonization device is the "waste carbonization device" (hereinafter referred to as "electronic") of Korean Patent Publication No. 10-2004-0009041, which is dried as the waste is transported by the driving means of the rotating drum. It is a carbonization device in which temperature rising → carbonization is performed step by step.

In addition, there is a "multistage screw dryer" (hereinafter referred to as "the latter") registered under Korean Utility Model Registration No. 20-206603, which arranges a plurality of drying cylinders with screws adjacent to each other, and is used for the top drying. The drying object injected into the cylinder is continuously transferred from the upper part to the lower part and discharged through the lowermost drying cylinder. The hot air injected into the lowermost drying cylinder is continuously transferred from the lower part to the upper part through the uppermost drying cylinder. It is a multistage screw dryer to be evacuated.

In the case of the above-mentioned conventional carbonization device, in the case of the "electronic", the combustion gas outlet is connected to the damper between the combustion chamber and the burner by the combustion gas suction pipe for the complete combustion of the incomplete combustion gas by the combustion chamber having the burner. It is complicated, and the hot air flow passages are connected to the multi-stage in a state in which each rotating drum is penetrated by a double, so there is a problem in that the use of the earth, such as occupy a lot of installation space.

In addition, since the latter type | mold multistage screw dryer injects a direct hot air into the screw housing of a drying cylinder, the drying efficiency of a drying object is very low because there is a lot of temperature change, and drying and carbonization efficiency is good because it adheres well to the inner peripheral surface. There is a problem falling.

Therefore, the present invention was developed in view of the above-described conventional problems, and an object of the present invention is to form a carbonization section in one carbonization container as long as possible to secure an installation space, and to carbonize more stably and efficiently. The present invention provides a multi-stage carbonization apparatus for organic waste using indirect heat that can be treated.

Another object of the present invention is to provide a multi-stage carbonization apparatus for organic waste using indirect heat, which can be conveniently installed in a single layer or a double layer according to the amount of carbonization of the organic waste.

Another object of the present invention is to increase the carbonization speed by removing the moisture of the organic waste to be introduced first, and to reduce the amount of fly ash or dust generated during the carbonization process of the organic waste to reduce the environment The present invention provides a multi-stage carbonization device for organic waste using indirect heat to prevent contamination.

In order to achieve the above object, the present invention provides a sealed carbonization passage through which the internal temperature is maintained at high temperature and thermally insulated so as to carbonize organic waste by an electric heater; A screw conveyor installed in the carbonization treatment tank and dropping the organic waste introduced into the upper waste inlet to the lower waste outlet; When constructing an organic waste carbonization furnace, a plurality of screw conveyors are installed in a plurality of rows by stacking a plurality of screw conveyors downward in a carbonization container along a longitudinal direction, and facing waste outlets between the top screw conveyor and the bottom screw conveyor. And waste inlet by chute, but some of the chutes are installed with deodorizing pipe line, and the upper chute of the top screw conveyor and the lower chute of the waste outlet of the bottom screw conveyor ( The chute) is exposed to the outside of the carbonization canister and characterized in that the carbonization canister is installed in a single or double layer structure according to the waste throughput.

Then, the multi-stage screw conveyor installed downward in the carbonization processing cylinder is characterized in that the center is installed to be staggered and staggered.

In addition, when a plurality of superheat conductors are bonded to the outer circumferential surface of the top screw conveyor into which the organic waste inside the carbonization container is first introduced, the internal temperature is prevented from dropping rapidly, so that the moisture drying effect of the organic waste is good, and thus the purpose can be effectively achieved.

The present invention carbonizes organic waste more stably because it is carbonized by indirect heating for as long as possible by a continuous multi-stage screw conveyor installed in a plurality of rows inside a closed carbonization container maintained at a temperature of 300 to 400 ° C. There is an effect that can be carbonized efficiently.

In addition, depending on the carbonization throughput and processing conditions, it is easy to use a carbonization canister as a single layer or additionally install it in multiple layers. Since the carbonization canister is compact in size, the installation area is small and the installation space is easy and the operating cost is low. It works.

In addition, since a large number of super-heat conductors with excellent thermal conductivity are installed on the screw conveyor where organic waste is first inputted, energy savings can be effected by shortening the processing time by increasing the indirect heating efficiency in an enclosed space, and the structure and process are simple. The failure rate is less effective.

In addition, it saves operating cost with low power and is easy to collect odors.Carbonized products are environmentally friendly products such as deodorant (activated carbon), sound absorbing material, soundproofing material, heating auxiliary fuel, moisture control agent for livestock farms, and soil removing agent for acid soil improvement. It can be utilized.

Hereinafter, the preferred configuration and operation for achieving the object of the present invention will be described with reference to the accompanying drawings.

1 is a cross-sectional view showing a state in which a multistage carbonization apparatus according to the present invention is installed in a single layer, FIG. 2 is a longitudinal cross-sectional view for showing the internal structure of the multistage carbonization apparatus according to the present invention, and FIG. 3 is a multistage carbonization of the present invention. It is a cross-sectional view which shows the apparatus installed in two layers.

In the configuration of the present invention shown in the closed carbonization bin 100 for maintaining a high temperature so that the internal temperature is carbonized organic waste by the electric heater 101; Installed in the carbonization processing container 100, the upper waste inlet 111 and the lower waste outlet 112 is provided at both ends, the organic waste introduced into the conveying screw 113 to the waste outlet 112, Falling screw conveyor 110; The organic waste carbonization apparatus can be said to be the same as before.

Features of the present invention is installed in multiple stages by stacking a plurality of screw conveyors 110 along the longitudinal direction inside the carbonization cylinder 100 in a multi-stage upper and lower chute (120a) and lower chute at the top and bottom (chute) 120b, the upper chute 120c, and the lower chute 120d were each provided by the some carbonization process line A (B) provided.

In addition, the waste outlet 112 and the waste inlet 111 that face each other between the top screw conveyor 110 and the bottom screw conveyor 110 of each carbonization line A and B are chute 120. But connected to some of the chute 120, characterized in that the deodorizing pipe line 130 is installed to deodorize the odor gas and water vapor complex.

In addition, the upper chute 120a (120c) and the waste outlet 112 of the bottom screw conveyor 110 installed at the waste inlet 111 of the top screw conveyor 110 of each carbonization line (A) (B). The lower chute (120b) (120d) installed in the upper surface and the bottom surface of the carbonization processing container 100 is installed to be exposed so that the carbonization processing container 100 can be used in a single layer or a multi-layer structure according to the waste throughput. do.

Here, the carbonization cylinder 100 is closed, so the temperature rise is easy, and there is a significant expansion pressure therein. However, it is possible to use it more safely because it is equipped with safety by installing an air vent and a safety valve in the carbonization processing container 100.

In the figure, reference numeral 102 is an insulating heat insulating material that is filled between the inner and outer shell of the carbonization processing cylinder 100, 140 is a series of power of the electric motor to the transfer screw 113 of each screw conveyor 110. Chain gear for transmission

The present invention will be described with reference to FIGS. 1 and 2 illustrating that the carbonization treatment cylinder 100 is installed in a single layer.

Since the carbonization cylinder 100 maintains a temperature of 300 to 400 ° C. stably by the plurality of electric heaters 101, the carbonization cylinder 100 forms a plurality of carbonization lines A and B in such interior. Screw conveyor 110 also maintains a fairly high temperature even if the internal temperature receives indirect heat.

In this state, when organic waste is introduced into the waste inlet 111 of the top screw conveyor 110 through the upper chute 120a of one side of the carbonization line A, the organic waste is discharged by the transfer screw 113. After being transferred to 112, it is dropped downward through the waste outlet 112.

At this time, a plurality of screw conveyors 110 at the bottom of the top screw conveyor 110 are connected to the chute 120 in a state where the waste inlet 111 and the waste outlet 112 are opposite to each other and the inlet and outlet 112 face each other. Since the injected organic waste is sequentially discharged through the multi-stage screw conveyor 110 to the lower chute 120b, moisture is evaporated and dried, and carbonization is gradually performed.

Here, if the lower chute 120b of the bottom screw conveyor 110 and the upper chute 120c of the other carbonization line B are connected with separate transfer conveyors, the two carbonization lines A and B may be separated from each other. As a result, the line for the carbonization process is longer, so that the carbide having passed through the carbonization line (A) is discharged through the lower chute (120d) while passing through the carbonization line (B).

In the present invention, one stage of the screw conveyor 110 may be installed in one carbonization processing container 100, but for the efficiency of operation, the screw conveyor 110 of the multi-stage may be installed in a plurality of rows. Through a multi-stage multi-stage screw conveyor 110 can process a large amount of organic waste at the same time it can maximize the throughput compared to the installation space.

That is, when the organic waste is carbonized while passing through the stacked screw conveyor 110 in a row, the carbonization state of the discharged carbide may be insufficient depending on the moisture content or type of the organic waste. Is carbonized when the lower chute 120b of one carbonization line A and the upper chute 120c of another carbonization line B are connected to a separate transfer conveyor (not shown) or artificially transferred and re-injected. Since the process line can be made longer, good carbide can be obtained.

In addition, the plurality of rows of carbonization line (A) (B) is inclined outward when the carbide falling from the waste outlet 112 of the upper screw conveyor 110 falls to the waste inlet 111 of the lower screw conveyor 110. Since the deodorizing pipe line 130 is installed in the chute 120, there is little concern that the odorous gas and water vapor generated during the carbonization process may fall into the deodorizing pipe line 130 when discharged to the carbonization pipe line.

In addition, the carbonization cylinder 100 is installed in a multilayer structure as shown in FIG. 3, and the lower chute 120b of the upper carbonization cylinder 100 and the upper chute 120a of the lower carbonization cylinder 100 are connected to each other, and When the lower chute 120b of the carbonization bin 100 is connected to the upper chute 120c of the upper carbonization bin 100 of another carbonization line B with a separate transfer conveyor (not shown), the carbonization process The longer treatment lines allow for maximum waste throughput and treatment efficiency, and the continuous addition of carbonizers even in tight installation spaces.

When the multi-stage screw conveyor 110 is installed downward in the carbonization processing container 100, the present invention is repeatedly installed in a staggered staggered center of the screw conveyor 110 within a limited carbonization container area. Since more screw conveyor 110 can be installed in the installation area can be maximized.

In addition, the present invention is the first and second screw conveyor 110 of one side of the carbonization processing line (A) in which the organic waste is first introduced into the carbonization processing line (A) (B) installed in a plurality of rows inside the carbonization processing container 100 The outer circumferential surface is characterized by being installed by attaching a plurality of super-heat conductors 150 with good thermal conductivity along the longitudinal direction.

That is, the first and second screw conveyor 110 of the carbonization processing line (A) is carbonized because the internal temperature of the organic waste is significantly reduced compared to other screw conveyors when moisture-containing organic waste is introduced, thereby reducing the drying efficiency of the water. When the speed is slowed, the superheat conductor 150 having good thermal conductivity on the outer circumferential surfaces of the first and second screw conveyors 110 can prevent the internal temperature from falling, so that moisture of organic waste can be removed more quickly. The process can be done quickly.

The present invention is to carbonize the organic waste using the indirect heat in a state in which the temperature inside the carbonization cylinder 100 is stably maintained at a high temperature by the electric heater 101, so that fly ash generated in a large amount during the carbonization process is generated. (Fly ash) and dust generation can be significantly reduced.
