Description

  The present invention relates to a fuel oil production apparatus.

  Conventionally, various proposals have been made regarding a fuel oil production apparatus that generates fuel oil from raw oil such as waste oil (see, for example, Patent Document 1).

  Patent Document 1 describes a fuel oil production apparatus provided with stirring means including a cylindrical body and a rotor. In this method, a raw material oil mixed with waste oil and water is introduced into a cylindrical body, and the rotor is rotated at a high speed to agitate the raw material oil to produce a fuel oil in an emulsion state.

JP 2003-013073 A

  However, in the fuel oil manufacturing apparatus described in Patent Document 1, since the rotor rotates at high speed, frictional heat is generated, but the cylinder is only naturally radiated from the outer periphery, and the raw material oil is contained in the cylinder. The temperature gradually increases and saturates at a predetermined temperature. Since the temperature of the raw material oil in the cylindrical body varies depending on the type of oil and the mixing ratio of oil and water, the quality of the produced fuel oil such as viscosity and temperature is not stable.

  In addition, when using a raw material oil containing a large amount of volatile components, if the temperature rising due to frictional heat increases, combustible gas may be generated, and the risk of explosion must also be considered.

  Then, an object of this invention is to provide the manufacturing apparatus of the fuel oil which can stir raw material oil at fixed temperature.

An apparatus for producing fuel oil comprising a stirring means including a rotor and a driving means for rotating the rotor, comprising temperature adjusting means for adjusting the temperature of the raw material oil inside the cylindrical body.

(2) In the aspect of the above (1), the temperature adjusting means supplies a temperature adjusting medium to a jacket provided so as to cover the cylindrical body and a space between the jacket and the cylindrical body. Means and a temperature controller for heating and cooling the temperature control medium may be included.

(3) In the aspect of (2), the temperature adjusting means is a cooling means that uses the temperature adjusting medium as a refrigerant body and cools by the refrigerant body, and the cooling means includes a radiator as the temperature adjuster. And a temperature control valve that opens and closes a circulation path formed between the radiator and the inside of the jacket, and a circulation means as the supply means for circulating the refrigerant body in the circulation path.

(4) In the above aspect (3), the temperature control valve may be adjusted by a thermostat mechanism.

(5) In any one of the above aspects (1) to (4), a temperature sensor that measures the temperature of the raw material oil may be provided inside the cylindrical body.

Thereafter, the U-shaped upper part is crimped inward as indicated by the broken line, and the brush-like projection 24 is fitted to the holder 24A. The presser 24B is a long stainless steel wire.

  Returning to FIG. 1, the temperature adjusting means 30 includes a jacket 31 provided so as to cover the cylindrical body 21, a supply means 34 for supplying a temperature adjusting medium to a space between the jacket 31 and the cylindrical body 21, It includes a temperature control valve 33 that opens and closes a conduit for circulating the temperature control medium, and a temperature controller 32 that heats and cools the temperature control medium.

  As shown in FIG. 2, the jacket 31 has a cylindrical shape provided concentrically with the cylindrical body 21, and both ends are fitted and integrated with an outer lid 31 </ b> A common to the cylindrical body 21. The jacket 31 is provided with a temperature control medium inlet at a position as far as possible from the feedstock inlet 21A, and a temperature control medium outlet at a position as far as possible from the temperature control medium inlet. ing.

  Here, the temperature adjusting means 30 may heat or cool the raw material oil in the cylindrical body 21 depending on the required temperature of the fuel oil. Below, the case where a cooling means is employ | adopted as the temperature control means 30 is demonstrated.

  The cooling means 30 includes a radiator 32 as a temperature controller, a temperature control valve 33, and a circulation means 34 as a supply means. The radiator 32 cools the refrigerant body as a temperature control medium. The temperature control valve 33 opens and closes a circulation path formed between the radiator 32 and the inside of the jacket 31, and operates by a thermostat mechanism to circulate or stop the refrigerant body. The circulation means 34 circulates the refrigerant body in the circulation path, and a pump is used.

  The cooling means 30 is configured to maintain the temperature of the raw material oil in the cylindrical body 21 at about 70 to 80 ° C. Although cooling water is used for the refrigerant body, coolant liquid or cooling gas may be used.

  As described above, according to the embodiment of the present invention, in the fuel oil manufacturing apparatus, the cylindrical body of the stirring means is covered with the jacket, and the temperature control medium is supplied to the inside of the jacket. Thereby, the temperature of the raw material oil in the cylindrical body is kept constant. Furthermore, since sound and vibration are attenuated by the temperature control medium inside the jacket, noise and vibration due to rotation of the rotor are also reduced. Moreover, the strength of the stirring means can be ensured by the integrated structure of the cylindrical body, the jacket, and the outer lid.

  In addition, according to the embodiment of the present invention, the fuel oil manufacturing apparatus moves the introduced raw material oil forward along the rotor and agitates by a large number of protrusions during the movement, so that the cavitation is cylindrical. It is a simple structure generated inside the body. Therefore, the fuel oil production apparatus can produce fuel oil at 500 liters / hour.

  The type of raw material oil used in the fuel oil production apparatus according to the embodiment of the present invention is rapeseed oil, safflower oil, cottonseed oil, soybean oil, corn oil, used for business or general household use in restaurants, food factories, etc. , Sesame oil, coconut oil, olive oil, castor oil, other vegetable oils, edible waste oils including lard, head, fish oil, and other animal oils, industrial waste oils such as kerosene, light oil, heavy oil, etc. altered by use or long-term storage, or A mixture of these waste oils or a mixture of waste oil and new oil may be used. In addition, when these waste oil contains an insoluble solid substance, it is good to remove with a filter. Alternatively, the raw material oil may be non-edible plant Jatropha (jatropha) oil or the like.

  Fuel oil produced by mixing water with oil has good combustion efficiency, and in particular, a mixture of water in the range of 10 to 30% by weight with respect to oil is preferable. When mixing water with oil, if an ultrasonic wave or an electric field is added, or far infrared rays are irradiated, raw material oil will be easily in an emulsion state.

  Further, a gas containing oxygen such as air may be blown into the raw material oil in a range of 1 to 5% by volume with respect to the raw material oil. Thereby, the apparent viscosity of raw material oil falls and the rotational resistance of the rotor 22 reduces. Moreover, generation | occurrence | production of cavitation is accelerated | stimulated by containing gas.

According to this, the temperature of the raw material oil in the cylindrical body can be adjusted more uniformly.
