Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. In addition, the embodiment described below does not unduly limit the content of the present invention described in the claims, and the entire structure described in this embodiment is not necessarily essential as the solution means of the present invention.

Figure 1 is a block diagram showing the configuration of a pyrolysis device of a liquid material according to an embodiment of the present invention.

As shown in the drawings, the pyrolysis device for a liquid material according to an embodiment of the present invention, pyrolysis means for heating and thermally decomposing the liquid material, gas reforming means for removing chlorine from the pyrolysis gas generated during the thermal decomposition of the liquid material, Refining oil producing means for producing refined oil using the reformed gas and carbonaceous material discharge means for continuously discharging the carbon (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 liquid material is indirectly heated in an oxygen-free or low oxygen atmosphere, a pyrolysis space is formed in a reducing atmosphere, and the liquid material is decomposed to evaporate into a gas or a liquid. What does not remain solid.

That is, it can be seen that the liquid substance + heat = gas (non-condensed gas) + liquid (oil) + solid (char).

First, referring to Figures 1 and 2, the configuration of the thermal decomposition means will be described. The pyrolysis means is configured to include a pyrolyzer body 210 to maintain a high temperature and low oxygen atmosphere to continuously pyrolyze the liquid material by indirect heating.

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

Operation of the transfer pump in the main hopper is input to the heat exchanger 242 installed on the top of the pyrolyzer body, the input amount of the liquid material is controlled by the sensor installed in the heat exchanger 242.

The sensing sensor detects the upper and lower limit values of the liquid material, and when the liquid material reaches the lower limit position, the transfer pump operates to inject the liquid material into the pyrolyzer body. When the upper limit position is reached, the transfer pump stops. The liquid material is not introduced into the body of the heat exchanger 242 installed on the pyrolysis unit.

Therefore, it is possible to maintain a constant amount of the liquid material introduced into the pyrolyzer body. In addition, the amount of the liquid material introduced is kept constant, thereby minimizing heat loss to the outside of the pyrolysis means, minimizing the amount of air introduced into the pyrolysis means, and also serves to prevent backflow of air.

Inside the pyrolyzer body 210, a pyrolysis screw 220 for transferring and pyrolyzing the liquid material introduced therein is rotatably installed by the driving 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.

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

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

Referring back to FIG. 2, the pyrolyzer body 210 is divided into a first body 211, a second body 213, and a third body 215 in the order of the progress of the liquid 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 liquid 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. As the liquid material moves due to the difference in the rotational speed between the screw 220 and the second body 213, the thermal decomposition of the preheating, heating, and vaporization 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 liquid material introduced from the drying means is moved to the second body 213 while the pyrolysis 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.

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 liquid body does not leak between the steps formed between the first body 211 and the second body 213 by the first sealing unit 212, and the second body 213 does not leak from the first body 211. The inflow of liquid material is natural. Accordingly, the thermal decomposition of the liquid substance 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 prevents the backflow of the 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 the outer circumference of the second drying 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 generated. The second dry body 213 is rotated by being transferred to the dry body 213.

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

At this time, the second drying body 213 is rotated at a relatively slow speed compared to the pyrolysis screw, by the difference with the rotational speed of the pyrolysis screw 220 provided in the second body 213. The liquid 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 liquid material can be thermally decomposed in a smaller space.

On the other hand, on the inner circumference of the second body 213 is formed a blocking projection (213a) at regular intervals. It is possible to prevent the liquid material from flowing backward in the second body 213 rotated by the blocking protrusion 213a. In addition, since the liquid material transferred to the second body 213 is transferred through the respective blocking protrusions 213a step by step, the liquid material can sufficiently stay in the second body 213 section. The pyrolysis effect can be maximized.

At this time, the screw blade of the pyrolysis screw 220 in the second body 213 section so as to correspond to the portion where the blocking projection (213a) is formed, and the portion where the blocking projection (213a) is not formed. It is formed by repeatedly increasing and decreasing the size of the outer diameter.

As the material moves in the section of the second body 213, the liquid material completely vaporizes from the liquid into the gaseous material, and the residue of the material having lost the physical properties is in the form of carbon to the third body 215 section. Will move.

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. As shown in FIG. 5, the second sealing unit 216 includes a first bushing 217 coupled to a second flange portion 215 ′ formed at the front end of the third body 215, and the first bushing 217. And a second bushing 218 engaging the front end of the bushing 217. 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 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 a process in which the heat source supplied from the combustion chamber 250 heats the liquid material in the pyrolyzer body 210 and is discharged. ) 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 desalination apparatus 550, the chlorine gas is inevitably generated during the thermal decomposition process of the liquid material containing the PVC-based additive having a chlorine component in the liquid material.

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 active, the gas with less carbon chain that 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 a substance containing a large amount of oil components, tar, a dark viscous liquid, is generated. The main components thereof are formed as aromatic hydrocarbons by binding to each other in the decomposed gas components. 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 dechlorination-treated pyrolysis gas, and a refining oil producing means 800 for generating the refining oil through the precipitation condensation apparatus.

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, to explain the thermal decomposition method of the liquid material according to an embodiment of the present invention.

Liquid material including waste oil, PCBc, oil sand, liquid polymer compound generated in the process is introduced into the pyrolysis means through the main hopper, the liquid material transferred to the pyrolyzer body 210 is pyrolysis chamber 240 Pyrolyzed by the indirect heating method of the heat source provided as, when the liquid material is introduced into the pyrolyzer body 210, the material melted and vaporized while being transferred to the right direction based on Figure 1 to maintain an atmosphere of high temperature and low oxygen state It is continuously pyrolyzed by heat applied indirectly in the pyrolysis chamber 240.

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 material in a small space.

The pyrolysis gas generated after the thermal decomposition is stayed in the gas retention tower 510 provided on the upper side of the pyrolyzer body 210 while indirectly applying high temperature heat to the liquid material to be thermally decomposed and then transferred to the dechlorination tower.

The pyrolysis gas transferred after the pyrolysis passes through the first desalination unit 550 and the second desalination unit 560 and then is transferred to the refinery oil producing means 800, and the diesel oil and heavy oil according to the boiling point from the refined oil producing means 800. Create

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.

Although the present invention has been described with reference to the embodiment thereof, the present invention is not limited thereto, and various modifications and applications are possible. That is, those skilled in the art will readily understand that many modifications are possible without departing from the gist of the invention.
