In addition, one Example described below does not unduly limit the content of this invention described in the Claim, and the whole structure described in this Embodiment is not necessarily required as a solution of this invention.

1 is a block diagram schematically showing the configuration of a pyrolysis apparatus for a solid combustible material according to an embodiment of the present invention.

As shown in the drawings, the pyrolysis apparatus for a solid combustible material according to an embodiment of the present invention, a pyrolysis means for heating and thermally decomposing the combustible combustible material, a gas for removing chlorine from the pyrolysis gas generated during pyrolysis of the combustible material And reforming means, refining oil producing means for producing refined oil using the reformed gas, and carbonaceous material discharge means for continuously discharging carbonized material (char) discharged after pyrolysis from the pyrolysis means.

The pyrolysis principle used in the pyrolysis system of the present embodiment configured as described above is that when a solid combustible material is indirectly heated in an oxygen-free or low oxygen atmosphere, the pyrolysis space is formed in a reducing atmosphere, and the combustible material is decomposed to evaporate into a gas or a liquid. What does not remain solid.

That is, it can be seen that the combustible material (meaning a flammable polymer compound) + heat = gas (non-condensing gas) + liquid (refined oil) + solid (char).

First, referring to Figures 1 and 2, the configuration of the thermal decomposition means will be described. The pyrolysis means comprises a pyrolyzer body 210 to maintain a high temperature and low oxygen atmosphere to continuously pyroly decompose combustible materials by indirect heating.

One side of the pyrolyzer body 210 is provided with a main hopper for the input of the pulverized solid combustible material. The combustible combustible material introduced through the main hopper is moved to the pyrolyzer body 210 to pyrolyze.

The main hopper is provided with a sensor so that the amount of combustible combustible material is always stored in the main hopper constantly. The detection sensor automatically adjusts the feeding amount of an input conveyor (not shown) of the solid combustible material so that the solid combustible material does not always fall below the set value.

Inside the pyrolyzer body 210, a pyrolysis screw 220 for transporting and pyrolyzing the combustible material introduced through the automatic input device 400 is rotatably installed by the drive motor 260.

The pyrolysis screw is configured to include a drive shaft 220 connected to the drive motor 230, and a screw blade 221 formed on the outside of the drive shaft 220. The pyrolysis screw is rotated by receiving power from the driving motor 230.

Outside the pyrolyzer body 210 is provided with a pyrolysis chamber 240 made of a heat insulating material to continuously decompose the combustible material by indirect heating by maintaining a high temperature (350 ~ 500 ℃) and low oxygen atmosphere.

On the other hand, among the pyrolysis gases generated during pyrolysis of combustible materials, C ₂ H ₆ , C ₃ H ₈ , C ₅ H ₁₂ (ethane gas, propane gas, butane gas) dominate the main species as light gases with little carbon ring condensation. At the lower side of the pyrolysis chamber 240, a combustion chamber 250 for supplying high temperature heat to the pyrolysis chamber 240, as shown in FIG. 3B, is used as a heat source for pyrolyzing the combustible material transported by burning it. ) And a burner 251 is provided in the combustion chamber 250.

Referring back to FIG. 1, the pyrolyzer body 210 is divided into a first body 211, a second body 213, and a third body 215 in the order of progress of the combustible material. The body is stepped to enlarge the inner diameter step by step to perform the pyrolysis process while going through a three-step process. At this time, the first body 211 and the third body 215 is fixed and installed, the second body 213 is installed to be rotatable.

In the section of the first body 211, the combustible material introduced from the drying means is transferred to the second body 213 by the rotation of the pyrolysis screw 220, and in the section of the second body 213, pyrolysis. Due to the difference in the rotational speed between the screw 220 and the second body 213, the combustible material is moved, and the portion of which thermal decomposition of the preheating, raising the temperature, and vaporizing is substantially performed. In the third body 215 section, the residue which is pyrolyzed is discharged, and the pyrolysis gas is transferred to the second pyrolysis chamber.

Specifically, the configuration of each of the pyrolyzer body 210 will be described.

First, the first body 211 is installed to be fixed, the combustible material introduced from the drying means is moved to the second body 213 while the thermal decomposition screw 220 is rotated.

At this time, a first sealing unit 212 is provided between the rear end of the first body 211 and the front end of the second body 213. The first sealing unit 212 has the same configuration as the second sealing 216, which will be described later, is the same as the configuration shown in FIG.

Specifically, the first sealing unit 212 includes a first bushing coupled to the first flange portion formed at the front end of the second body, and a second bushing coupled to the front end of the first bushing. Packings are provided on the inner circumferences of the first bushing and the second bushing, respectively, to double seal between the first body and the second body.

The first sealing unit 212 does not leak the combustible material between the step formed between the first body 211 and the second body 213, the second body 213 in the first body 211 As a result, the influx of flammable substances occurs naturally. Accordingly, pyrolysis of the combustible material moving from the first body 211 to the second body 213 is naturally performed. In addition, due to the first sealing unit 212, the friction generated by the rotation of the first body 211 and the second body 213 is minimized, and the first body 211 and the second body 213 The exact level can be maintained, and prevent the back flow of the combustible material from the second body 213 to the first body 211.

Next, a rotation motor 260 is provided at one side of the second body 213 so that the second body 213 is rotatable. At this time, the second body 213 is supported by the tire 213c so that the second body 213 is stably rotated.

Specifically, power is transmitted to the drive gear 264 through the

belts

261 and 262 to transmit the driving force of the rotary motor 260. A driven gear 213b is formed on an outer circumference of the second body 213, and the driving gear 264 and the driven gear 213b are engaged with each other so that the driving force generated in the rotary motor 260 is the second body. The second body 213 is rotated by being transferred to 213.

At least one tire 213c is provided on an outer circumferential surface of the second body 213. The tire 213c is supported by the support roller 266 so that the second body 213 can stably rotate.

At this time, the second body 213 and the drying screw is rotated at a relatively slow speed, the flammability by the difference between the rotational speed of the pyrolysis screw 220 provided in the second body 213 The material is gradually moved compared to the inside of the first body 211. Therefore, it is possible to provide at least three times more heat transfer area than when the second body 213 is fixed, so that more decomposition of the combustible material can be performed in a smaller space.

As the combustible material moves in the section of the second body 213, the combustible material completely vaporizes from solid to liquid, liquid to gaseous material (sometimes, directly sublimates from solid state to gaseous state), Residue of the combustible material which lost its intrinsic properties is moved to the third body 215 section in the form of carbon.

The second sealing unit 216 is provided between the rear end of the second body 213 and the front end of the third body 215. The second sealing unit 216 is coupled to the first bushing 217 coupled to the second flange portion 215 ′ formed at the front end of the third body 215, and to the front end of the first bushing 217. The second bushing 218 is configured to include. Inner circumferences of the first bushing 217 and the second bushing 218 are provided with

packings

217a and 218a, respectively, to double seal between the second body 213 and the third body 215. .

The second sealing unit 216 minimizes friction caused by the rotation of the second body 213 and the third body 215, and the second body 213 and the third body 215 are precisely horizontal This can be maintained.

The third body 215 is fixedly installed, the front end portion 215a of the third body 215 and the screw blade 221 of the pyrolysis screw 220 for connection with the second body 213. Correspondingly formed in a circular shape (see Figure 3c), the middle portion 215b of the third body 215 is formed in a streamlined structure so that a space is formed on the upper portion of the screw blade 221 (see Figure 3d). The pyrolysis gas generated at the time of pyrolysis temporarily stays in the space above the screw blades, and the pyrolysis gas can be smoothly moved to the gas retention tower 510 which will be described later.

In addition, the rear end portion 215c of the third body 215 is a section for discharging ash which has undergone all thermal decomposition, and is formed in a circular shape so as to correspond to the outer diameter of the screw blade to minimize the gap between the screw blade and the third body 215. (See FIG. 3E). Accordingly, fly ash generated after pyrolysis is prevented from moving to the gas retention tower 510.

On the other hand, the discharge hole 223 is formed in the screw blade in the section of the second body 213 and the third body 215. Since the discharge hole 223 is formed in the screw blade, the pyrolysis gas generated in the pyrolysis process may naturally move to the gas retention tower 510, and the stirring of the flammable material may be performed smoothly, thereby improving the pyrolysis efficiency.

And one side of the pyrolyzer body 210 is provided with a nitrogen input device (not shown). When a fire occurs due to inadvertent use or malfunction of equipment during operation of the pyrolyzer, it is possible to extinguish the fire by injecting nitrogen into the pyrolyzer body 210 from the nitrogen input device.

When the pyrolysis is completely discharged from the pyrolyzer body 210 is discharged continuously, when the ash is discharged through the valve body 620 such as a slide gate or a rotary valve provided on one side of the third body 215 The air can be blocked from entering the pyrolyzer body 210.

Next, the gas reforming means is a gas detention tower 510 connected to the outlet side of the pyrolyzer body 210 and a first desalination apparatus 550 and a second desalination apparatus for removing chlorine from the reformed gas. And 560.

The spiral screw 520 is provided inside the gas retention tower 510 to sufficiently secure the residence time of the heat source in the process of being discharged after heating the combustible material in the pyrolyzer body 210 by the heat source supplied from the combustion chamber 250. ) Is provided. The gas is discharged while rotating spirally along the spiral screw 520 to secure a time for the gas to stay in the gas retention tower. A driving motor 530 is coupled to an upper end of the spiral screw 520 to provide a driving force for rotating the spiral screw 520 at a predetermined speed.

The pyrolysis gas generated inside the pyrolyzer body 210 is molecularly bonded at a high speed in the inner space of the gas retention tower 510, and detection starts from a substance having a large molecular weight having a long chain of carbon chains.

A wax or tar component mainly composed of 24 or more carbon chains is detected. The tar and dewaxing processes are performed in the inner space of the gas retention tower 510. At this time, the screw blade of the spiral screw 520 rotated by the drive motor 530 is configured to have an outer diameter corresponding to the inner diameter of the gas retention lead is tar or carbonized material attached to the inner peripheral surface of the gas retention tower 510 By scraping the role of separating from the inner circumferential surface of the gas retention tower 510.

The heat source supply chamber 540 is provided on the outside of the gas retention tower 510 to communicate with the pyrolysis chamber 240 through a connection passage. Since the heat source supply chamber 540 is provided, the temperature may be corrected so that the pyrolysis gas rising through the gas retention tower 510 does not condense.

That is, the high heat of about 800 ~ 900 ℃ used as indirect heat in the pyrolysis chamber 240 is introduced into the heat source supply chamber 540 surrounding the gas retention tower 510 while falling to about 500 ~ 600 ℃, the gas The temperature of the retention column 510 is maintained at about 200 ~ 250 ℃. Therefore, the pyrolysis gas in the gas retention tower 510 is transferred to the first desalination unit 550 without condensation.

In the first desalting apparatus 550, the chlorine gas is inevitably generated during the thermal decomposition of the combustible material containing the PVC-based additive having a chlorine component among the combustible materials.

The temperature of the gas retention tower 510 is calibrated to about 200 to 250 ° C. so that no chlorine compound is generated, and the first desalination unit 550 removes the chlorine component by exposing the pyrolysis gas to a basic aqueous solution. do. That is, in the first desalination apparatus 550, by chemical reaction of HCl + NaOH → NaCl + H ₂ O, reaction products having 7 to 23 carbon chains are continuously generated in pyrolysis gas to remove chlorine. .

One side of the first desalination unit 550 of the gas reforming means is provided with a second desalination unit 560 for additionally removing chlorine from the dechlorinated gas.

In the second desalination unit 560, since pyrolysis gas from which chlorine is first removed is continuously formed in the first desalination unit 550, molecular hydrogen is sprayed to quench the pyrolysis gas by spraying an aqueous sodium hydroxide (NaOH) solution. In this way, generation of benzenes can be suppressed, and the formation of long chains in the carbon chain can be suppressed to obtain light oil.

In addition, since the chemical reaction of HCl + NaOH → NaCl + H ₂ O is actively performed, gas with a small amount of carbon chain which is not condensed is discharged in a clean state. Therefore, it is possible to minimize the generation of wax with a long carbon chain.

When pyrolyzing flammable substances containing a large amount of oil components, tar, which is a black viscous liquid, is generated, and its main components are formed by combining with each other in the decomposed gas components while taking a stable form as an aromatic hydrocarbon. In order to minimize the generation of tar, the second desalting apparatus 560 minimizes the space and time at which tar can occur.

One side of the second desalination apparatus 560 is provided with a gas purification means 700 for purifying the dechlorinated pyrolysis gas, and a refining oil producing means 800 for generating refined oil using the pyrolysis gas.

The gas purification means 700 includes a precipitation condensation apparatus for condensing the dechlorinated pyrolysis gas under a stable atmosphere to generate a primary refined oil, and a purification apparatus for improving gas quality. The gas purified through the gas purification means 700 is stored in the gas storage tank through a water seal device and then supplied to the combustion chamber 250 through a pressure regulating device to be used as a gas for combustion.

The refined oil producing means 800 is a storage tank for storing the primary refined oil supplied from the settling condensation device, an oil-separator for oil-separating the primary refined oil stored in the storage tank and the oil-separated refined oil according to the boiling point gasoline, diesel And a distillation column separated by heavy oil.

The carbonization material discharge means is a configuration for discharging the carbonized material generated after pyrolysis from the pyrolyzer body 210, and comprises a discharge hopper 610 formed at the end of the pyrolyzer body 210.

Carbonization material generated after the pyrolysis is continuously discharged through the end of the pyrolyzer body 210, discharge hopper to block the pyrolysis gas discharged from the outside air and pyrolyzer body 210 when the carbonized material is discharged from the outside. The slide gate 620 is provided. The slide gate 620 is preferably configured in at least two stages to maximize the blocking of the outside and prevent malfunction.

The carbonized material continuously discharged through the carbonized material discharge means is discharged to the carbonized material forming means 900 to produce solid fuel. Since the discharged carbonized material is discharged by mixing foreign substances such as superfluous, iron, and non-ferrous metals together, the foreign materials and carbonized material are completely separated through the crushing device and sorting device, and then the foreign materials are removed, and only the carbonized material is passed through the molding device. It produces fuel having a shape, such as briquettes.

Hereinafter, a thermal decomposition method of a solid combustible material according to an embodiment of the present invention will be described.

Solid combustible materials including metal fragments, plastics, paper, industrial combustibles, etc. are shredded to a predetermined size in the crusher after arrival, and the soil, dust, etc. are removed through a sorting machine, and non-ferrous metals are selected and selected. Flammable materials are recycled. The sorted solid combustible material is transferred to a grinder and ground to a relatively small size. The combustible combusted material is secondly re-selected through a magnetic screening device and partly recycled.

The pulverized solid combustible material is introduced into the pyrolysis means through the main hopper, and the combustible material transferred to the pyrolyzer body 210 is pyrolyzed by an indirect heating method of a heat source provided to the pyrolysis chamber 240, and the combustible material is pyrolyzed. When introduced into the body 210, the combustible material that is melted and vaporized while being transferred to the right direction based on FIG. 1 is continuously pyrolyzed by heat applied indirectly in the pyrolysis chamber 240 maintaining an atmosphere of high temperature and low oxygen state. .

At this time, while the second body 213 of the pyrolyzer body 210 rotates together with the pyrolysis screw 220, the second body 213 moves slowly due to the difference in the rotational speed with the pyrolysis screw 220. At least three times more heat transfer area can be provided than when 213 is fixed. Therefore, it is possible to pyrolyze a large amount of combustible material in a small space.

The pyrolysis gas generated after the pyrolysis is stayed in the gas retention tower 510 provided above the pyrolyzer body 210, and is indirectly heated to the combustible material to be pyrolyzed, and then transferred to the dechlorination tower.

The pyrolysis gas transferred after the pyrolysis passes through the first desalting unit 550 and the second desalting unit 560 and then is transferred to the refining oil producing means 800.

And the carbonized material lost the properties after the pyrolysis is discharged through the discharge hopper provided on the lower side of the pyrolyzer body (210). At this time, the discharged carbonized material is discharged by mixing foreign matters such as superfluous, iron, non-ferrous metal, etc., and produces a fuel having a predetermined shape, such as briquettes, through a crusher and a sorting device.

As mentioned above, although demonstrated with reference to the Example of this invention, this invention is not limited to this, A various deformation | transformation and an application are possible. That is, those skilled in the art will readily appreciate that many modifications are possible without departing from the spirit of the invention.
