Description

Technology Field

[0001] The present invention relates to a chamber system for a pyrolysis liquefaction device, and more particularly to a chamber system for a pyrolysis liquefaction device in which a plurality of combustion chambers form an array structure sharing an input end, and the plurality of combustion chambers sequentially share the pyrolysis gas according to the amount of pyrolysis gas generated in the pyrolysis furnace, thereby reducing the pressure of the pyrolysis gas applied to the combustion chambers and efficiently heating the pyrolysis furnace. Background Technology

[0002] Currently, polymer materials composed of hydrocarbons, such as plastics and vinyl, which are used for various purposes, are seeing increased emissions due to industrial development. Since most of these materials are disposed of through incineration and landfilling, they are emerging as a cause of serious environmental pollution in the atmosphere, soil, and oceans, necessitating the development of new treatment technologies for polymer waste.

[0003] Furthermore, various measures for the circular use of resources are being devised, and consequently, liquefaction device technologies for recycling various types of waste plastics are becoming more active. For example, a recycling method for polymer waste, such as waste plastics and vinyl manufactured using petroleum as a raw material, involves applying heat in an oxygen-free reducing atmosphere to induce a decomposition reaction in which the carbon chains constituting the polymer break, transforming it into multiple low-molecular-weight substances. As the waste dissolves and becomes gaseous, it is liquefied through a cooling device to obtain pyrolysis oil. The bonds of some hydrocarbons break even at 200°C, and violent pyrolysis reactions occur when the temperature is raised to 350–400°C.

[0004] These pyrolysis liquefaction devices can be broadly classified into batch type, in which waste is heated and melted while loaded into a pyrolysis furnace, and continuous type, in which waste is continuously fed into a pyrolysis furnace and pyrolyzed while being heated.

[0005] Batch-type pyrolysis liquefaction devices feed a fixed amount of waste raw material into a pyrolysis furnace, ensure that all of the input waste reacts, and repeat the process of removing residue remaining in the furnace and feeding in raw material once the reaction is complete. In this case, the reactor is lowered to an appropriate temperature before the waste is fed in again, and there are also processes where the raw material itself is fed in manually without being crushed.

[0006] Continuous pyrolysis liquefaction systems continuously carry out a series of processing steps, including the pretreatment and supply of waste raw materials, pyrolysis reactions, the discharge and treatment of residues, and the purification of products. In the case of continuous systems, almost all processes are automated; therefore, while the initial investment cost for plant installation is high, there are advantages such as lower operating costs due to reduced operating personnel and high product quality.

[0007] Conventional pyrolysis liquefaction devices utilize a method in which the pyrolysis furnace comes into direct contact with a heating means and is heated directly by the heating means. However, this direct heating method poses a risk that the pyrolysis furnace may be deformed or damaged due to thermal expansion, and there is a problem that foul odors are generated when products such as waste gas and pyrolysis oil, which are the byproducts of the pyrolysis liquefaction process, are fed into the heating means. Prior art literature

[0008] Korean Registered Patent Publication No. 10-2060532 (Published Dec. 23, 2019) The problem to be solved

[0009] The objective of the present invention is to provide a chamber system for a pyrolysis liquefaction device that maintains the pressure of the pyrolysis gas flowing into the combustion furnace at a constant level by first heating the combustion furnace using the pyrolysis gas and pyrolysis oil generated in the pyrolysis furnace and thereby indirectly heating the pyrolysis furnace, while allowing multiple combustion furnaces to share the pyrolysis gas in consideration of the fact that the pressure of the pyrolysis gas generated in the pyrolysis furnace is not constant.

[0010] In addition, another objective of the present invention is to provide a chamber system for a pyrolysis liquefaction device that minimizes explosion phenomena inside the combustion chamber or excessive emission of air pollutants by keeping the pilot burner in a constantly operating state. means of solving the problem

[0011] The above objective is achieved according to the present invention by a combustion furnace that heats the pyrolysis furnace by burning pyrolysis gas generated in the pyrolysis furnace, and when pyrolysis oil is generated in the pyrolysis furnace, heats the pyrolysis furnace using the pyrolysis oil as fuel, and bypasses the pyrolysis gas to an adjacent combustion furnace when the pressure of the pyrolysis gas exceeds a preset reference pressure; a bypass valve provided between the pyrolysis gas inlet of the combustion furnace and the fuel input end of the other combustion furnace; a pyrolysis oil pump that introduces the pyrolysis oil into the combustion furnace; and a control unit that, when the pressure of the pyrolysis gas introduced into the combustion furnace exceeds the reference pressure, opens the bypass valve to bypass the pyrolysis gas to the other combustion furnace, and when the pyrolysis oil is produced in the pyrolysis furnace, operates the pyrolysis oil pump to guide the pyrolysis oil into the combustion furnace.

[0012] In addition, it may further include a pilot burner that supplies gas and air to and ignites the combustion furnace before the pyrolysis oil and pyrolysis gas are produced in the pyrolysis furnace.

[0013] Here, the pilot burner is in a constant operating state and can be increased or decreased depending on the amount of pyrolysis gas and pyrolysis oil introduced into the combustion furnace.

[0014] In addition, the apparatus further includes a UV sensor for determining whether combustion is occurring inside the combustion furnace; and a damper connected to the pyrolysis gas inlet; wherein, if the combustion state inside the combustion furnace is not detected through the UV sensor, the control unit preferably controls the damper to regulate the amount of air flowing into the combustion furnace. Effects of the invention

[0015] According to the present invention,

[0016] 1) The pyrolysis furnace is indirectly heated using a combustion furnace to minimize aging and damage to the pyrolysis furnace.

[0017] 2) The combustion furnace utilizes the pyrolysis gas and pyrolysis oil generated in the pyrolysis furnace, so it does not require a large amount of separate fuel, making it highly economical.

[0018] 3) By arranging the combustion furnaces in a multiple array and bypassing the pyrolysis gas to an adjacent combustion furnace when the pressure of the pyrolysis gas flowing into the main combustion furnace exceeds the reference pressure, stable operation is possible, and incomplete combustion of the pyrolysis gas within the combustion furnace can be minimized, making it environmentally friendly.

[0020] Hereinafter, a chamber system for a pyrolysis emulsification apparatus according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention.

[0021] Furthermore, throughout the specification, when a part is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Also, throughout the specification, the term “on” means being located above or below the subject part, and does not necessarily mean being located on the upper side with respect to the direction of gravity.

[0022] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that in the accompanying drawings, identical components are indicated by the same reference numerals whenever possible. Furthermore, detailed descriptions of known functions and configurations that may obscure the essence of the present invention will be omitted. For the same reason, some components in the accompanying drawings may be exaggerated, omitted, or schematically depicted.

[0023] FIG. 1 illustrates an overall block diagram of a pyrolysis emulsification apparatus to which a chamber system for a pyrolysis emulsification apparatus according to one embodiment of the present invention is applied.

[0024] Referring to FIG. 1, the overall configuration of the pyrolysis system to which the chamber system for the pyrolysis emulsification device according to the embodiment is applied includes a pyrolysis furnace (300), a pyrolysis furnace housing (310), a heating means (400), a discharge means (500), a gas separator (600), a cooling means (700), a gas storage means (800), and a pyrolysis oil storage means (900) supply means.

[0025] The input means (200) is connected to a raw material supply means (100), such as a hopper, to receive polymer waste and feed it into the interior of the pyrolysis furnace (200), so that polymer waste is continuously fed into the interior of the pyrolysis furnace (200) even during the pyrolysis process in the pyrolysis furnace (300).

[0026] When polymer waste is introduced into the pyrolysis furnace (300) through the input means (200), air is also introduced into the pyrolysis furnace (300). If the oxygen concentration in the pyrolysis furnace (300) increases, there is a risk of explosion as combustible gas burns. In such cases, the risk of explosion can be reduced by introducing an inert gas into the pyrolysis furnace (300) or the input means (200).

[0027] The pyrolysis furnace (300) is a means for pyrolyzing polymer waste loaded into an internal space by heating and melting it, and is formed in a roughly cylindrical shape and arranged horizontally.

[0028] The pyrolysis furnace (300) is equipped with an inlet on one side in the horizontal direction for introducing polymer waste and an outlet on the other side for discharging a product that has been heated, melted, and pyrolyzed. The pyrolysis furnace (300) can rotate by the rotational force provided by a motor (not shown) installed on one side.

[0029] Polymer waste such as waste plastic and waste vinyl is automatically and continuously fed into the pyrolysis furnace (300) from the input means (200), heated and melted while being stirred by the rotation of the pyrolysis furnace (300), and the melted product can be transported to the discharge port while being guided by a spiral (not shown) formed horizontally in the internal space.

[0030] The pyrolysis furnace housing (310) is formed to surround the outside of the pyrolysis furnace (300) with a spaced-apart space as a means for indirectly heating the pyrolysis furnace (300) with heated gas. The pyrolysis furnace (300) can be indirectly heated as heated gas passes through the spaced-apart space between the inner surface of the pyrolysis furnace housing (310) and the outer surface of the pyrolysis furnace. That is, the pyrolysis furnace (300) is heated in an indirect heating method through heat exchange with heated gas, rather than a direct heating method by a heat source.

[0031] A heating means (400) that heats a gas and supplies the heated gas to a combustion chamber (420) includes an electric heating chamber (410) and a combustion chamber (420).

[0032] The combustion chamber (420) may be formed in multiple numbers. In FIG. 1, it can be seen that the combustion chambers are given reference numerals 420 and 430.

[0033] The combustion chamber (420) and the combustion chamber (430) have the same structure and a pyrolysis gas inlet is jointly connected, and are configured to allow pyrolysis gas to be bypassed in one direction from the combustion chamber (420) to the combustion chamber (430) using a bypass valve. Preferably, the bypass valve may be a solenoid valve that controls the on / off flow of a fluid or gas. The bypass valve will be described in detail later with reference to FIG. 2.

[0034] The electric heating chamber (410) and the combustion chamber (420) are directly connected to each other and can be selectively operated depending on the temperature and the condition of the pyrolysis product. The heating means (400) is separated from the pyrolysis furnace (300) so that maintenance work can be easily and efficiently managed.

[0035] The electric heating chamber (410) is a means for heating air introduced from the outside with an electric heater and serves as a heat source for heating the air before the start of the pyrolysis process or before the non-condensed form of pyrolysis gas or pyrolysis oil, which is the product of the pyrolysis process, is generated in the early stages.

[0036] The electric heating chamber (410) includes a chamber body having a space into which external air is introduced, and an electric heater that heats the air introduced into the chamber. External air can be introduced into the chamber body of the electric heating chamber (410) and heated in the chamber body. The heated external air can be discharged from the electric heating chamber (410), pass through the combustion chamber (420), and be introduced into the pyrolysis furnace housing (310).

[0037] The combustion chamber (420) is a means for heating gas or oil, and serves to heat gas introduced from the outside by selecting and burning one or more of the pyrolysis gas supplied from the gas supply means (800) or the pyrolysis oil supplied from the pyrolysis oil storage means (900).

[0038] In this way, if pyrolysis gas is supplied and used as a heat source, the heating efficiency is improved because the pyrolysis furnace (300) is heated using high-temperature combustible gas as a heat source, and the gas generated in the pyrolysis process is purified and discharged after combustion once more, so pollutants can be reduced.

[0039] When the combustion furnace (421) heats the pyrolysis furnace (400) by burning non-condensing pyrolysis gas, the pyrolysis gas is irregular during the pyrolysis process, and since there is a large variation in the amount and composition depending on the composition of the polymer waste, there may be a risk of fire or explosion if the pyrolysis gas is rapidly supplied to the combustion furnace (421). Therefore, when the pyrolysis furnace (300) is heated and the waste plastic reaches the pyrolysis temperature and begins to generate non-condensing pyrolysis gas or pyrolysis oil through the pyrolysis process, the operation of the electric heating chamber (410) can be stopped.

[0040] When the temperature of the pyrolysis furnace (300) exceeds a certain temperature, the operation of the electric heating chamber (410) is stopped, and one or more of the pyrolysis gas or pyrolysis oil are selected and combusted to supply the heated gas to the pyrolysis furnace housing (310).

[0041] Since the non-condensing pyrolysis gas is irregular during the pyrolysis process and the amount produced varies significantly depending on the composition of the polymer waste, it is desirable to send the pyrolysis gas to the combustion chamber (420) as consistently as possible during the pyrolysis process. When the amount of pyrolysis gas produced falls within a preset standard range, the non-condensing gas is supplied to the combustion chamber (420) in real time. When the amount of pyrolysis gas produced decreases below the preset standard range, the non-condensing gas is collected until it reaches the standard range, and during this time, pyrolysis oil is supplied to the combustion chamber (420) to heat the gas with the pyrolysis oil, or the combustion chamber (420) can be heated using a gas such as LPG or LNG.

[0042] Meanwhile, the gas discharged after heat exchange in the housing (310) through pyrolysis is reintroduced into the combustion chamber (420), and the gas with residual heat is reheated, thereby increasing thermal efficiency.

[0043] The polymer waste melted in the pyrolysis furnace (300) is supplied to a gas separator (600) through a discharge means (500), and the gas separator (600) can separate liquid pyrolysis oil and gaseous pyrolysis gas. After the separated pyrolysis gas and pyrolysis oil are cooled by a cooling means (700), they can be stored in a gas storage means (800) and a pyrolysis oil storage means (900), respectively.

[0044] For the above, a pyrolysis emulsification apparatus to which the chamber system for a pyrolysis emulsification apparatus of the present invention is applied has been described. Hereinafter, with reference to FIG. 2, the chamber system for a pyrolysis emulsification apparatus will be described in detail.

[0045] FIG. 2 illustrates a block diagram of a chamber system for a pyrolysis emulsification apparatus according to one embodiment of the present invention.

[0046] The chamber system for a pyrolysis liquefaction device according to the embodiment is characterized by a plurality of combustion chambers (420) arranged in an array within a heating means (400), and a connecting structure between the arrayed combustion chambers (420) and the combustion chamber (430). At this time, since the structure of the combustion chamber (420) and the combustion chamber (430) is identical, the description of the combustion chamber (430) is omitted.

[0047] The combustion chamber (420) may include a combustion furnace (421), a fuel bypass valve (422), a pyrolysis oil pump (423), a damper (424), a UV (UltraViolet ray) sensor (425), a pilot burner (426), a regulator (427), pressure sensors (428a, 428b), a preheater (423a), and a control unit (429).

[0048] The combustion furnace (421) is a composite combustion device capable of burning pyrolysis gas, pyrolysis oil, LPG (Liquefied Petroleum Gas) and LNG (Liquefied Natural Gas), and may include a fuel input section (421a) for receiving these fuels and an outlet (421b) for indirectly heating the pyrolysis furnace (300) by discharging high-temperature combustion gas to the pyrolysis furnace (300) after burning the fuel.

[0049] When the combustion furnace (421) is first operated, combustion can be started through a pilot burner (426). The pilot burner (426) uses LPG or LNG as fuel and is ignited using an igniter (426a), and the ignited fuel (LNG or LPG) can indirectly heat the pyrolysis furnace (300) after being burned in the combustion furnace (421).

[0050] When the gas combusted through the pilot burner (426) indirectly heats the pyrolysis furnace (300) and melts the polymer waste in the pyrolysis furnace (300), pyrolysis gas is produced first, and then pyrolysis oil is produced. Therefore, the main fuel of the combustion furnace (421) can be changed according to the sequence of fuel (LNG, LPG) combustion - pyrolysis gas combustion - pyrolysis oil combustion of the pilot burner (426).

[0051] At the time when pyrolysis oil is generated, the control unit (429) operates the preheater (423a) and the pyrolysis oil pump (423), heats the pyrolysis oil to a temperature suitable for combustion through the preheater (423a), and then operates the pyrolysis oil pump (423) to pump the pyrolysis oil to the fuel input terminal (421a).

[0052] The pilot burner (426) may be kept in a constant operating state from the time the combustion furnace (421) is first started until the combustion furnace (421) is stopped, in order to ensure stable combustion of the combustion furnace (421). However, it is desirable for the pilot burner (426) to maintain a constant combustion state by reducing the inflow of fuel (LNG, LPG) once pyrolysis gas or pyrolysis oil begins to flow into the combustion furnace (421) in earnest, so that only a minimum amount of fuel (LPG, LNG) flows into the combustion furnace (421).

[0053] The pyrolysis gas or pyrolysis oil generated in the pyrolysis furnace (300) is produced by the melting of polymer waste. Since the amount of pyrolysis gas and pyrolysis oil extracted is not constant depending on the type or condition of the polymer waste, the pilot burner (426) is kept in a constant operating state. The amount of fuel burned by the pilot burner (426) can be increased or decreased depending on the amount of pyrolysis gas or pyrolysis oil flowing into the combustion furnace (421).

[0054] One side of the bypass valve (422) is connected to the fuel input terminal (421a) of the combustion chamber (420) through the regulator (427), and the other side can be connected to the fuel input terminal of the other combustion chamber (430). When the pressure inside the combustion chamber (421) is above the reference pressure (e.g., 0.18 MPa), the bypass valve (422) is opened by the control unit (429) to bypass the fuel (pyrolysis gas) heading toward the combustion chamber (421) to the adjacent other combustion chamber (430). At this time, the other combustion chamber (430) has the same structure as the combustion chamber (420) and can receive the pyrolysis gas flowing in through the bypass valve (422) and burn it in the built-in combustion chamber.

[0055] Accordingly, the pressure of the combustion furnace (421) is reduced, and the combustion furnace (421) can be controlled so that an explosion occurs when burning excessive pyrolysis gas.

[0056] The control unit (429) measures the pressure of the pyrolysis gas passing through the regulator (427) and the pressure inside the combustion furnace (421) through pressure sensors (428a, 428b), and is connected to the UV sensor (425) of the pilot burner (426) to detect whether combustion is occurring in the combustion furnace (421) through flame detection or to determine whether incomplete combustion is occurring inside the combustion furnace (421) by analyzing the light spectrum of the burned flame.

[0057] If no flame is detected in the combustion furnace (421), the control unit (429) can restart the combustion furnace (421), and if it is determined from the optical spectrum analysis results that incomplete combustion is occurring in the combustion furnace (421), the control unit (429) can control the damper (424) to increase the amount of air applied to the fuel input terminal (421a).

[0058] Additionally, when the pressure of the combustion chamber (421) exceeds the reference pressure through the pressure sensor (428b), the control unit (429) applies power to the bypass valve (422) to open the bypass valve (422) and changes the inflow path of the pyrolysis gas so that the pyrolysis gas flowing into the fuel input terminal (421a) flows through the regulator (427) to the fuel input terminal of the adjacent combustion chamber (430).

[0059] Meanwhile, when burning pyrolysis oil in the combustion furnace (421), the regulator (427) can be controlled to minimize or block the inflow of pyrolysis gas to the fuel input terminal (421a). The inflow of pyrolysis oil into the combustion furnace (421) means that the pyrolysis oil has started to be produced in the pyrolysis furnace (300), and if the pyrolysis oil is available, it means that there is no need to additionally inflow pyrolysis gas into the combustion furnace (421). However, as mentioned above, since the production volume and heat content of the pyrolysis oil may vary depending on the type, temperature, and condition of the polymer waste, a portion of the pyrolysis gas may be continuously injected into the combustion furnace (421) in preparation for a shortage of pyrolysis oil, and the pilot burner (426) may be kept in a constant standby state.

[0060] FIG. 3 illustrates a conceptual diagram of a bypass connection structure of a combustion chamber according to an embodiment.

[0061] Referring to FIG. 3, the apparatus is equipped with a main combustion chamber (420) and a sub-combustion chamber (430, 440b).

[0062] When the internal pressure of the combustion furnace (421) on the combustion chamber (420) side exceeds the reference pressure, the bypass valve (422) is opened, and the pyrolysis gas is bypassed to an adjacent combustion chamber (430).

[0063] At this time, the pyrolysis gas is introduced into the fuel input terminal (not shown) of the combustion chamber (430) and combusted in the combustion chamber (430), and the combusted gas is discharged to the pyrolysis furnace (300) to indirectly heat the pyrolysis furnace (300).

[0064] If a large amount of pyrolysis gas is generated in the pyrolysis furnace (300) and a pressure level that is difficult to handle is applied to the combustion chamber (430), the combustion chamber (430) opens the bypass valve (432) to bypass the pyrolysis gas back to the combustion chamber (440).

[0065] The pyrolysis gas bypassed from the combustion chamber (430) flows into the fuel input of the combustion chamber (440) and is burned, and the burned gas is likewise used to heat the pyrolysis furnace (300).

[0066] At this time, since the combustion chamber (430) bypasses the pyrolysis gas to the combustion chamber (440), the pressure of the pyrolysis gas is reduced, and additional pyrolysis gas can be distributed from the combustion chamber (420) accordingly.

[0067] Depending on the production capacity of pyrolysis gas and pyrolysis oil of the pyrolysis furnace (300), the number of combustion chambers (430, 440) may not be the two exemplified, but may be three or more. The point is that the pyrolysis gas flowing into the combustion chamber (420) is distributed among multiple sub-combustion chambers, allowing the pyrolysis gas produced in the pyrolysis furnace (300) to be continuously utilized, and as the multiple combustion chambers (420, 430, 440) heat the pyrolysis furnace (300) together, the capacity of the pyrolysis furnace (300) to produce regenerative gas and pyrolysis oil can be increased. In short, if the number of combustion chambers (420, 430, 440) is three or more as exemplified, the capacity of the pyrolysis furnace (300) may be increased to a size appropriate to that. However, it is not limited thereto.

[0068] The embodiments and drawings attached to this specification merely clearly illustrate a part of the technical concept included in the present invention, and it is obvious that various modifications and specific embodiments that can be easily inferred by a person skilled in the art within the scope of the technical concept included in the specification and drawings of the present invention are all included within the scope of the rights of the present invention.
