The sediment and water are separated or discharged by using a natural precipitation method from the supplied raw material, and the raw material is moved to the discharge site (S16).

b) input phase

Looking at the input step (S20) briefly introduced into the reaction tank 201 through the method as shown in Figure 6 as shown in Figure 6 as follows.

First, the first water level sensor 116 installed at the discharge portion of the pretreatment unit 110 detects the pretreated raw material (S21).

When the first water level sensor 116 detects the raw material, the first opening / closing valve 118 is turned on by the controller 400 and is opened (S22).

As the first open / close valve 118 is opened, raw materials are introduced into the reaction tank 201 through the first pipe 117 (S23).

At the same time, the second on-off valve 122 is turned on by the controller 400 and is opened (S24).

As the second open / close valve 122 is opened, the catalyst stored in the first catalyst supply unit 120 is introduced into the reaction tank 201 (S25).

c) manufacturing stage

Referring to Figure 7 briefly look at the manufacturing step (S30) that the biodiesel is produced through the reaction of the raw material and the catalyst added to the reaction tank 201 as follows.

If it is determined that the supply of the catalyst is additionally determined according to the amount of catalyst supplied through the first catalyst supply unit 120 into the reactor 201, the second catalyst supply unit 202 is in communication with The catalyst is further supplied through the third pipe 202-1 by the opening of the third open / close valve 202-2 (S31).

It is checked whether the mixed raw material of the raw material and the catalyst in the reaction tank 201 is filled with an appropriate amount for processing (S32).

When it is determined that the raw material in the reaction tank 201 is filled in an appropriate amount, the raw material and the catalyst are mixed evenly using the stirrer 204, the pump unit 205 is turned on to circulate the mixed raw material for a predetermined time and At the same time, the heating unit 206 is turned on to heat the mixed raw material to be maintained at a predetermined temperature for a predetermined time (S33).

After the pump unit 205 and the heating unit 206 are turned off, the mixed raw material is left to stand for a predetermined time, and then the initial product and the by-product are separated from the mixed raw material by natural precipitation. By-products are discharged to the by-product storage 213 through the opening of (S34).

Closing the sixth on / off valve 213-2 and opening the third on / off valve 202-2 to supply washing water for washing the initial product into the reaction tank 201, and at the same time to prevent saponification of the raw materials. The saponification inhibitor is supplied through the fourth pipe 203-1 by opening the fourth on / off valve 203-2 (S35).

The initial product and the washing water are mixed through the stirrer 204 to circulate through the pump unit 205 and heated to a predetermined temperature through the heating unit 206 (S36).

The mixture of the initial product, the washing water and the anti-saponification agent is allowed to stand for a predetermined time and then separated into the final product and the discharge water, and then discharged to the drying unit 211 through the opening of the fifth open / close valve 211-2. (S37).

The discharged water discharged from the drying unit 211 is heated to evaporate with water vapor (S38).

The final product is circulated through the pump unit 205, the steam in the reactor 201 is discharged to the outside using the blower unit 207, and heated and dried by the heating unit 206. At this time, an antioxidant for preventing oxidation of the raw material or a flow point strengthening agent for increasing the flow point in order to prevent the raw material from freezing is supplied through the eighth pipe 217-1 by the eighth open / close valve 217-2 ( S39).

d) collection step (S40)

Looking briefly at the collection step (S40) for collecting the final product produced in the reaction tank 201 through Figure 8 as follows.

When the drying is completed in the manufacturing step (S30) and the final product is manufactured, a sensor (not shown) disposed inside the reaction tank 201 operates to inform that the biodiesel production is completed.

The controller 400 receiving the manufacturing completion signal through the sensor opens the seventh open / close valve 300-2 so that the final product is collected into the container 310 (S41).

The second level sensor 320 detects the final product collected by the container 310 (S42).

When the second water level sensor 320 detects the final product, the control unit 400 receiving the signal may move the container 310 by turning off the raw material pretreatment device and the production device (S43).

Then, the final product in the container 310 is discharged to the outside according to the operation of the second pump 332 and through the ninth pipe 331 by the opening of the ninth open / close valve 335 (S44).

At this time, the final product discharged to the outside through the discharge unit 330 as described above is the foreign matter is removed through the micro filter 333 installed in the ninth pipe 331.

In the above, the pre-treatment step (S10), the input step (S20), the manufacturing step (S30) and the collection step (S40) have been briefly described by dividing each step, but an example in which they are executed in connection with each other is as follows. .

The user who wants to manufacture the raw material by operating the biodiesel manufacturing system presses the start button of the controller 400.

When the start button is pressed, the raw material is supplied into the pretreatment unit 110, and the alarm sensor 112 detects the same and at the same time, the first water level sensor 116 has a plurality of 1, 2, 3 and low values. It is recognized as a step sends information of the pretreatment state and amount of the raw material to the control unit 400. At this time, when the raw material reaches the highest point of the first level sensor 116, the alarm of the alarm sensor 112 is not activated.

When the pretreated raw material is detected by the first water level sensor 116, the first opening / closing valve 118 is opened and after a few seconds, a raw material supply pump (not shown) is operated to supply the pretreated raw material into the reactor 201. When the supplied raw material reaches the contact point 1 of the third level sensor 208, the raw material supply pump is stopped and after a few seconds, the first opening / closing valve 118 is closed.

When the heating unit 206 inside the reaction tank 201 reaches a predetermined temperature, the second on-off valve 122 is opened and after a few seconds, a catalyst supply pump (not shown) operates to activate the catalyst into the reaction tank 201. Is supplied.

When the catalyst is supplied and the contact point 2 of the third water level sensor 208 is reached, the catalyst supply pump is stopped and after a few seconds, the second opening / closing valve 122 is closed.

At this time, the third open / close valve 202-2 may be opened to further supply the catalyst.

Then, while maintaining the reaction tank 201 for a predetermined time to maintain a predetermined temperature through the heating unit 206. That is, when the temperature is set to 65 ° C. and the temperature is reached, the power is automatically turned off. When the temperature is 60 ° C. or lower, the power is automatically turned on to operate the heating unit 206. At this time, it takes about 30 minutes.

Here, the first pump 205-2 operates for a predetermined operating time and is automatically left after that time. Here, the operation time is usually set to 30 minutes.

After the above settling time, the by-product is separated from the initial product, moves to the by-product storage 213 according to the opening of the sixth open / close valve 213-2, and reaches the contact point 3 of the third water level sensor 208 After that, the sixth open / close valve 213-2 is automatically closed.

When the sixth on-off valve 213-2 is closed after the by-product is discharged as described above, the third on-off valve 202-2 is opened to supply the washing water, and the washing water is supplied to the contact point 4 of the third level sensor 208. When reaching, the third on-off valve 202-2 is closed.

Then, after operating the heating unit 206 to maintain the preset washing temperature, the fourth open / close valve 203-2 is opened to supply the anti-saponification agent.

At this time, the mixture of the initial product and the washing water and the anti-saponification agent is circulated through the pump unit 205 for a predetermined time or a number of times and then left to stand for a predetermined time.

When the settling time is completed, the fifth on-off valve 211-2 is opened to discharge the discharged water, and when the discharge water reaches the contact point 3 of the third level sensor 208, the fifth on-off valve 211-2 is closed. Let it close

Here, water washing through the supply of the washing water as described above may be repeated several times or more depending on the user's intention.

After the discharged water is discharged as described above, a drying process is performed according to a predetermined temperature and time.

In the drying process, when the temperature is lower than the predetermined temperature value, the heating unit 206 is operated, and the pump unit 205 is selectively operated.

The blower unit 207 is operated while maintaining the temperature made by the heating of the heating unit 206 to discharge steam to the through hole 212-1.

Then, the eighth open / close valve 217-2 is opened while the pump unit 205 is operated so that the antioxidant is supplied for several seconds, and then the valve is closed.

Here, even when the operation of the pump unit 205 is completed, the blower unit 207 is operated for several seconds to discharge steam to produce a final product.

Then, the final product supply pump (not shown) is operated and the seventh open / close valve 300-2 is opened to send the final product to the container 310.

When the final product reaches the contact point 3 of the third level sensor 208, the final product supply pump is stopped and the seventh open / close valve 300-2 is closed.

When reaching the highest point of the sixth water level sensor 320 indicating that the supply of the final product is completed into the container 310, the seventh open / close valve 300-2 is closed and the discharge unit 330 is operated. Let's do it.

That is, the second product 332 of the discharge unit 330 is operated and the ninth open / close valve 335 is opened to discharge the final product to the outside.

In the processing process from the pretreatment unit to the collection unit as described above, when it is determined that the final product is completely moved to the collecting container 310, the process returns to the reaction process and the process starts again from the reaction.

The treatment process as described above can be done repeatedly from one to several times, initially set as an automated program, which is continuous if raw materials, catalysts, anti-saponification agents, antioxidants, pour point enhancers, containers and level sensors are not troublesome conditions.
