Definitions
- the present invention relates to an oil extraction system and method for pyrolyzing waste plastic materials, and more particularly, to an oil extraction system and method for producing oil from industrial wastes such as waste plastic materials and waste Styrofoam, by pyrolyzing the industrial wastes in a pyrolysis chamber of a furnace, condensing gas produced by pyrolysis, and separating oil and water.
- the oil extraction system according to the present invention improves efficiency of gas collection in a pyrolysis process, and thereby oil production efficiency and thereby increasing economical efficiency.
- a waste treatment system disclosed in Korean Patent Publication No. 1995-7048 has the following configuration.
- a waste decomposition furnace is configured with an inner furnace and an outer furnace.
- the inner furnace is installed to rotate with an axis of a double hollow shaft (inner and outer).
- One end of the double hollow shaft is connected to a reprocessing and collecting unit that is successively connected to an adsorption chamber containing active carbon, gas neutralization chamber containing neutralizing agent, and cooling chamber by using pipes.
- Gas pyrolyzed from wastes in the inner furnace is filtered, neutralized, and cooled while passing the above chambers.
- the outer furnace is formed in the outside of the inner furnace, and has a burning room formed at its bottom, a flue formed in a zigzag shape on the top of the outer furnace, and a cooling water jacket formed around the flue.
- the flue is connected to the adsorption chamber through a duct and one end of the adsorption chamber is connected to the gas neutralization chamber through a transport duct such that gas produced by the burning room is neutralized in the gas neutralization chamber and exhausted to the outside.
- a gas supply line is installed between the burning room and cooling chamber to supply the pyrolyzed gas into the burning room as a substitutive fuel.
- the pyrolyzed gas is transported to the reprocessing and collecting unit through a plurality of holes formed at the outer hollow shaft.
- films are formed in the holes by rotation of the outer hollow shaft while the inner furnace is rotated by a reduction motor, and the holes become blocked by the films. Accordingly, gas is not smoothly exhausted and oil extraction yield is decreased.
- An oil extraction system using waste plastic materials disclosed in Korean Patent No. 0486159 is configured with: a transport screw for transporting crushed waste plastic materials contained in a hopper by a motor; a reactor for producing gas containing oil from the waste plastic materials by heating the reactor with a burner; a cooling tower for cooling the gas containing oil; a primary filtering device; a catalyst tower for deodorizing and decolorizing; and a secondary filtering device.
- a pre-melting device is installed between the transport screw and reactor to convert the crushed waste plastic materials into a half-melt state by heating, which is to be transported to the reactor.
- this patent has a problem that gas containing oil is partially lost in the step of pre-melting the waste plastic materials. That is, gas is partially lost in the step of pre-melting and compressing the waste plastic materials such as Styrofoam and vinyl, and in the step of pyrolyzing the waste plastic materials. Therefore, oil extraction yield is decreased.
- the conventional waste treatment systems generally have a huge size.
- the volume of gas produced by pyrolyzing waste materials is relatively small and efficiency of collecting the pyrolyzed gas for reprocessing is low, and thereby economical efficiency of the waste treatment facility becomes low.
- hundreds of waste treatment systems were registered or applied for Korean patent, there is almost no waste treatment system practically running now. This means that most of the waste treatment systems registered or applied for Korean patents are not economical yet.
- the present invention has been made in view of the above problems, and an object of the present invention is to improve economical efficiency in an oil extraction system for pyrolyzing industrial waste materials such as waste plastic materials and waste Styrofoam, by pyrolyzing the waste materials in a pyrolysis chamber of a furnace, producing gas, efficiently collecting the pyrolyzed gas, condensing the gas, and separating oil and water.
- industrial waste materials such as waste plastic materials and waste Styrofoam
- Another object of the present invention is to reduce costs in waste treatment of waste plastic materials.
- Another object of the present invention is to prevent environmental pollution of soil and air by avoiding landfill and incineration.
- Another object of the present invention is to reduce import of energy sources in oil importing countries.
- an oil extraction system includes: a waste feeding device for supplying waste plastic materials contained in a hopper to a primary pyrolysis chamber (referred to ‘reactor’) through a feed inlet, the primary pyrolysis chamber pyrolyzing the supplied waste plastic materials; a double jacket furnace having a burner and for heating the primary pyrolysis chamber loaded in a burning room of the furnace; a rotation device for rotating the primary pyrolysis chamber loaded in the burning room of the furnace; a secondary pyrolysis chamber for re-pyrolyzing gas produced by the primary pyrolysis chamber, and for separating carbides and residue; a condenser for liquefying the gas separated from the secondary pyrolysis chamber by condensing and forming mixture of produced oil and water; and an oil-water separator for separating the produced oil and water condensed in the condenser.
- a waste feeding device for supplying waste plastic materials contained in a hopper to a primary pyrolysis chamber (referred to ‘reactor’) through a feed
- An oil extraction method utilizes the above oil extraction system to efficiently produce oil from industrial waste materials such as waste plastic materials and waste Styrofoam.
- waste treatment costs of waste plastic materials may be reduced, environmental pollution of soil and air may be prevented by avoiding landfill and incineration, import of energy sources may be reduced in oil importing countries, and gas suction rate and oil extraction yield may be improved by sucking a large amount of produced gas by using gas suction pipes formed with bent ends in the primary pyrolysis chamber.

Description
- 1. Field of Invention
- The present invention relates to an oil extraction system and method for pyrolyzing waste plastic materials, and more particularly, to an oil extraction system and method for producing oil from industrial wastes such as waste plastic materials and waste Styrofoam, by pyrolyzing the industrial wastes in a pyrolysis chamber of a furnace, condensing gas produced by pyrolysis, and separating oil and water. The oil extraction system according to the present invention improves efficiency of gas collection in a pyrolysis process, and thereby oil production efficiency and thereby increasing economical efficiency.
- 2. Description of the Related Art
- Various oil extraction systems using pyrolysis of industrial wastes such as waste plastic materials, waste Styrofoam, and waste tires, have been introduced.
- However, most of conventional pyrolyzing systems have a disadvantage of low economical efficiency, because oil extraction yield is not satisfactory compared with installation and operation costs of the pyrolyzing systems. Therefore, the conventional pyrolyzing systems are not successful in industrial applications.
- For example, a waste treatment system disclosed in Korean Patent Publication No. 1995-7048 has the following configuration. A waste decomposition furnace is configured with an inner furnace and an outer furnace. The inner furnace is installed to rotate with an axis of a double hollow shaft (inner and outer). One end of the double hollow shaft is connected to a reprocessing and collecting unit that is successively connected to an adsorption chamber containing active carbon, gas neutralization chamber containing neutralizing agent, and cooling chamber by using pipes. Gas pyrolyzed from wastes in the inner furnace is filtered, neutralized, and cooled while passing the above chambers. The outer furnace is formed in the outside of the inner furnace, and has a burning room formed at its bottom, a flue formed in a zigzag shape on the top of the outer furnace, and a cooling water jacket formed around the flue. The flue is connected to the adsorption chamber through a duct and one end of the adsorption chamber is connected to the gas neutralization chamber through a transport duct such that gas produced by the burning room is neutralized in the gas neutralization chamber and exhausted to the outside. A gas supply line is installed between the burning room and cooling chamber to supply the pyrolyzed gas into the burning room as a substitutive fuel.
- In this patent publication, the pyrolyzed gas is transported to the reprocessing and collecting unit through a plurality of holes formed at the outer hollow shaft. However, films are formed in the holes by rotation of the outer hollow shaft while the inner furnace is rotated by a reduction motor, and the holes become blocked by the films. Accordingly, gas is not smoothly exhausted and oil extraction yield is decreased.
- An oil extraction system using waste plastic materials disclosed in Korean Patent No. 0486159 is configured with: a transport screw for transporting crushed waste plastic materials contained in a hopper by a motor; a reactor for producing gas containing oil from the waste plastic materials by heating the reactor with a burner; a cooling tower for cooling the gas containing oil; a primary filtering device; a catalyst tower for deodorizing and decolorizing; and a secondary filtering device. A pre-melting device is installed between the transport screw and reactor to convert the crushed waste plastic materials into a half-melt state by heating, which is to be transported to the reactor. However, this patent has a problem that gas containing oil is partially lost in the step of pre-melting the waste plastic materials. That is, gas is partially lost in the step of pre-melting and compressing the waste plastic materials such as Styrofoam and vinyl, and in the step of pyrolyzing the waste plastic materials. Therefore, oil extraction yield is decreased.
- Additionally, the conventional waste treatment systems generally have a huge size. However, the volume of gas produced by pyrolyzing waste materials is relatively small and efficiency of collecting the pyrolyzed gas for reprocessing is low, and thereby economical efficiency of the waste treatment facility becomes low. Although hundreds of waste treatment systems were registered or applied for Korean patent, there is almost no waste treatment system practically running now. This means that most of the waste treatment systems registered or applied for Korean patents are not economical yet.
- The present invention has been made in view of the above problems, and an object of the present invention is to improve economical efficiency in an oil extraction system for pyrolyzing industrial waste materials such as waste plastic materials and waste Styrofoam, by pyrolyzing the waste materials in a pyrolysis chamber of a furnace, producing gas, efficiently collecting the pyrolyzed gas, condensing the gas, and separating oil and water.
- Another object of the present invention is to reduce costs in waste treatment of waste plastic materials.
- Another object of the present invention is to prevent environmental pollution of soil and air by avoiding landfill and incineration.
- Further, another object of the present invention is to reduce import of energy sources in oil importing countries.
- In order to achieve the above objects, an oil extraction system according to an exemplary embodiment of the present invention includes: a waste feeding device for supplying waste plastic materials contained in a hopper to a primary pyrolysis chamber (referred to ‘reactor’) through a feed inlet, the primary pyrolysis chamber pyrolyzing the supplied waste plastic materials; a double jacket furnace having a burner and for heating the primary pyrolysis chamber loaded in a burning room of the furnace; a rotation device for rotating the primary pyrolysis chamber loaded in the burning room of the furnace; a secondary pyrolysis chamber for re-pyrolyzing gas produced by the primary pyrolysis chamber, and for separating carbides and residue; a condenser for liquefying the gas separated from the secondary pyrolysis chamber by condensing and forming mixture of produced oil and water; and an oil-water separator for separating the produced oil and water condensed in the condenser.
- An oil extraction method according to another exemplary embodiment of the present invention utilizes the above oil extraction system to efficiently produce oil from industrial waste materials such as waste plastic materials and waste Styrofoam.
- According to the above exemplary embodiments of the present invention, waste treatment costs of waste plastic materials may be reduced, environmental pollution of soil and air may be prevented by avoiding landfill and incineration, import of energy sources may be reduced in oil importing countries, and gas suction rate and oil extraction yield may be improved by sucking a large amount of produced gas by using gas suction pipes formed with bent ends in the primary pyrolysis chamber.
