Description

TECHNICAL FIELD [0001] The present invention relates to a biofuel production system using plant oil,

TECHNICAL FIELD The present invention relates to a biofuel production system and a production method thereof, and more particularly, to a production system for manufacturing a biofuel with high efficiency by processing plants capable of extracting oil into raw materials and a manufacturing method thereof .

Most of our energy sources are fossil fuels such as petroleum and coal, but because of their limited reserves, they are expected to be depleted in the near future. Also, due to problems such as environmental pollution, interest in alternative energy and clean energy . Therefore, efforts to develop various types of alternative energy sources have been actively made to solve this problem.

Accordingly, various types of energy sources capable of replacing fossil fuels have been actively studied, and interest in biofuels called renewable energy is increasing.

These biofuels are produced by transesterification reaction of alcohol with triglyceride, which is a main component of fat and oil such as vegetable oil and animal fat, alkyl ester).

It is required to develop the technology in terms of resource recycling and environmental conservation as an alternative fuel. The vegetable oil is composed of glyceride which is a fatty acid ester of glycerol together with fatty acid and glycerol. Because the vegetable oil is very difficult to use as a fuel because of its high viscosity, fatty acid methyl esters and glycerin are obtained by using methanol, which is cheaper than oil and alcohols. The fatty acid ester production method includes a direct ester method and an ester exchange method.

The direct ester method is the most common method using the reaction of RCOOH + R'OH → RCOOR` + H2O. It is the most common method to heat the fatty acid and alcohol under high temperature without reaction at 135 ℃ ~ 250 ℃ or the sulfuric acid, phosphoric acid, alkali metal acetate, sulfate , Chlorides, oxides, para-toluene, and sulfonic acid as catalysts under mild conditions.

On the other hand, in the ester exchange method, an ester exchange reaction, which is a reaction in which a fatty acid, an alcohol or an ester is reacted at 60 ° C to 80 ° C according to an ester such as triglyceride to another kind of ester, is used. In particular, the reaction between an ester and an alcohol is called an alcoholysis, and an alkali catalyst such as sodium methoxide is used.

Most of the above-mentioned reaction steps are subjected to an esterification reaction. However, such a reaction mechanism has disadvantages in that water can be generated, a subsequent treatment device for removing the catalyst due to the use of a large amount of catalyst is required, and the efficiency and economical efficiency are low.

For example, Korean Laid-Open Patent Publication No. 99-16815 and Korean Laid-Open Patent Publication No. 1999-79052 disclose a method of regenerating a waste cooking oil to produce an alternative fuel, The cost of using water and the costs of wastewater treatment are high.

Recently, it is urgently required to develop a biofuel using only pure vegetable oil which does not require addition of a reactant or addition of a catalyst through the process of milking and refining only the vegetable raw material from which oil can be extracted. System development is urgently required.

Conventionally, the biofuel production system has a problem in that the production cost is high because the apparatus for heating and milking plants is large, and it takes a long time to preheat the large apparatus to a predetermined temperature and a large amount of fuel consumption.

Hereinafter, a method for producing a biofuel using the biofuel production system of the present invention will be described.

The raw material receiving portion 140 in a state of no content is joined to the raw material receiving portion coupling hole 133 of the rotary milking portion 130 (S100). The raw material receiving portion 140 is caught by the rotating and feeding portion 130 by the engaging end 142. [

Then, the driving motor 132 is operated to rotate the rotary milking unit 130 by a predetermined angle. That is, the raw material storage portion 140 is rotated so as to be positioned at the lower end of the hopper 112 of the lifting and lowering milking portion 110 (S110).

When the driving motor 132 is stopped, the cylinder 111 is lowered so that the raising and lowering milking portion 110 is lowered so that the hopper 113 is brought into contact with the raw material receiving portion 140 (S120). The opening and closing port 112 provided at the lower end of the hopper 113 is opened to allow the vegetable raw material in the hopper 113 to be filled in the raw material receiving portion 142 of the raw material receiving portion 140, (S130).

The lifting and lowering milking unit 110 is raised by the operation of the cylinder 111 and then the rotary milking unit 130 is rotated by a predetermined angle by the rotation of the driving motor 132. [ The raw material receiving portion 140 containing the vegetable raw material is rotated such that the upper portion of the ascending and descending milking portion 110 is positioned between the lower end of the heating portion 114 and the lower portion of the supporting milking portion 120 between the heating portions 123 ).

When the drive motor 132 is stopped, the lifting and lowering milking unit 110 is lowered by the operation of the cylinder 111 and the raw material storage unit 140 is held for a predetermined time by the upper heating unit 114 and the lower heating unit 123 (S150).

The lifting and lowering milking part 110 is lifted up by the operation of the cylinder 111 after a predetermined time and then the rotary milking part 130 is rotated by a predetermined angle by the operation of the driving motor 132 again. That is, the heated raw material receiving portion 140 is rotated so as to be positioned between the pressing portion 115 of the rising / falling milking portion 110 and the oil collecting portion 122 of the supported milking portion 120 (S160).

When the drive motor 132 is stopped, the lifting and lowering milking part 110 is lowered by the operation of the cylinder 111 to press the vegetable raw materials contained in the raw material receiving part 140 by the pressing part 115 (S170). The vegetable oil is milked from the pressurized vegetable raw material and the milk is discharged through the oil discharge hole 143 of the raw material storage portion 140 and collected through the oil collecting portion 122 of the supported milking portion 130 S180).

After the vegetable oil is milked, the raw material receiving portion 140 is rotated to the initial position by the operation of the drive motor 132 after raising the rising and falling milking portion 110. The raw material receiving portion 140 containing the vegetable raw material residue is pulled out from the raw material receiving portion coupling hole 133 of the rotary milking portion 130 by the operator or automatic apparatus. Then, the process can be repeated by coupling the new raw material receiving portion 140 to the raw material receiving portion coupling hole 133 again.

Meanwhile, as described above, it is also possible to simultaneously perform the step of containing the vegetable raw material in the raw material receiving portion 140 and the step of pressing the vegetable raw material simultaneously.

That is, at one side, the process of joining the raw material storage portion 140 to the raw material storage portion coupling hole 133 of the rotary milking portion 130 is repeatedly performed.

When the up / down milking unit 110 is lowered after the rotation of the rotary milking unit 130 by the operation of the drive motor 132, the hopper 113 is opened at one side to transfer the vegetable raw material to the raw material receiving unit The raw material receiving portion 140 is heated by the upper heating portion 114 and the lower heating portion 123 at the other side and the pressing portion 115 is heated by the raw material receiving portion 140 ) May be pressurized to allow the milking process to proceed.

The vegetable oil milked by the milking machine 100 of the present invention performs a sedimentation action in the end refining part 200 to precipitate the residue components and to discharge the precipitated sediment to the outside (S200).

The vegetable oil purified in the tip refining unit 200 is subjected to a reaction process so as to improve the components through the reaction unit 300 as in the known process (S300). To this end, mixing of the reaction material with vegetable oil promotes decolorization and deodorization as well as precipitation, acid value control through PH change. Also, it is preferable to perform the stirring operation in parallel to improve the reaction efficiency of the reaction part 300 as well known in the art.

In step S400, the vegetable oil is discharged to the rear end purification part 400 in the same manner as the front end purification part 200, with the second residue being discharged. The secondarily purified vegetable oil in the rear end purification unit 400 is finally filtered in the filter unit 500 (S500) and stored in the storage tank 600.

The oil introduced into the filtration tank 510 through the oil inlet 511 is sucked into the plurality of oil filtration filter units 530 by the suction pump 540 and collected by the filtration top plate 520, 512). At this time, the fine mesh filter 533 is contracted by the suction force of the suction pump 540 and pulled upward, and the inner elastic spring 532 is also compressed. Accordingly, the pores of the fine mesh filter 533 are reduced, and the vegetable oil is discharged through the fine mesh filter 533. However, the debris is trapped outside the fine mesh filter 533 and filtered.

When the operation of the suction pump 540 is stopped to stop the filtration, the retraction of the fine mesh filter 533 is released, and the resilient force of the elastic spring 532 returns to the original size. At this time, the debris attached to the outside of the fine mesh filter 533 is desorbed and deposited on the bottom of the filtration tank 510. When the amount of the debris is increased, the bottom valve of the filtration tank 510 is opened to remove the debris have.
