Description

  The present invention relates to an apparatus for atomizing a substance handled in various industries such as food, chemicals, and pharmaceuticals. In particular, the substance is emulsified, dispersed, stirred, or crushed so as to be uniform (or homogeneous) on the order of microns or less. The present invention relates to an apparatus for obtaining a stable particle size distribution by atomizing to a small particle size. The present invention also relates to a method of processing waste oil such as engine oil into fuel by using a atomizer.

  An APV type gorin homogenizer is known as a conventional atomizer for substances. This device has a configuration in which the valve faces the valve seat so as to have a slight gap at one opening of the valve seat. Under this configuration, the raw material fed under high pressure from the other opening of the valve seat is ejected radially outward of the valve from the gap and collides with the inner diameter wall of the impact ring. The material is atomized and homogenized. In this apparatus, a desired processing amount (10 t / h) can be obtained by adjusting the gap and setting the processing pressure of the raw material to several 107 Pa.

  In addition, as another conventional material atomization apparatus, an apparatus for atomizing a pressurized raw material using a narrow tube having a specific hole diameter or a generator (apparatus body) having a plurality of orifices (small holes) is known. (See Japanese Patent No. 3002432).

  Furthermore, in order to improve the above-described two conventional apparatuses, there is a substance atomization apparatus disclosed in Japanese Patent Application No. 2000-181600.

The cylindrical body is provided with an inlet portion for supplying the raw material to the inner cylinder on the side surface on one end side and an outlet portion for discharging the atomized raw material to the outside of the apparatus on the other end. The inner cylinder is disposed along the axial direction of the cylinder. In the side wall of the inner cylinder, a large number of holes consisting of a plurality of groups that penetrate to the hollow portion of the inner cylinder are formed. Here, the holes belonging to the same group are formed to have the same diameter.

  When the atomization process is performed, first, the inner cylinder is moved using an operation member provided at one end of the inner cylinder, and a group that takes an appropriate hole diameter with respect to the particle size of the substance in the raw material is provided at the inlet. Face to face. Next, the raw material is supplied to the inlet portion under high pressure, and the raw material is introduced into the hollow portion of the inner cylinder through a plurality of holes belonging to the group facing the inlet portion.

  Through this treatment process, the material in the raw material is atomized by shock waves generated when the vacuum bubbles generated by the delamination phenomenon of the highly pressurized raw material liquid are ruptured inside each hole. To be discharged. Therefore, a desired processing amount and particle size distribution can be obtained by repeating the above-described atomization processing a plurality of times while moving the inner cylinder and gradually changing the hole diameter.

  In addition, each modification demonstrated in 1st Embodiment is applicable to the atomization apparatus 110 of 4th Embodiment.

(Example)
Next, with reference to FIGS. 19 and 20, an example of manufacturing dimensions of the cylinder-type ceramic nozzle, that is, the inner cylinder 26, which is a main part in each casing used in the first embodiment will be described. The body diameter D of the inner cylinder 26 is 15 to 25 mm, and the body length L is 20 to 35 mm. Eight hole portions 21 are formed in the body in the radial direction of the inner cylinder 26 along the axial direction of the inner cylinder 26. The eight hole portions 21 penetrate the body in a cross shape, and the four hole portions 21 drilled in the same direction have an interval of 3 to 5 mm in the axial direction of the adjacent hole portion 21 and the inner cylinder 26. (P). Further, the two hole portions 21 drilled in a cross shape with each other do not cross each other because the interval between the two hole portions 21 is shifted by P / 2. The diameter of the axial passage 22, which is a hollow portion of the inner cylinder 26, is 5 mm and is connected to all eight holes 21. The thickness F of the closed portion of the axial passage 22 is 5 to 15 mm. Two types, an inner cylinder 26 having eight hole portions 21 having a hole diameter of 0.5 mm and an inner cylinder 26 having eight hole portions 21 having a hole diameter of 0.3 mm, are prepared as required.

  The atomizing device 12 incorporating the parent casing 17, the first additional casing 18a, the second additional casing 18b, and the third additional casing 18c, each having the inner cylinder 26 configured in such dimensions, is as follows. Has application examples.

  As shown in FIG. 21, the following steps are followed to process waste oil (substance) such as automobile engine oil to produce a high-quality fuel. First, the raw material is made by adding 10 to 50% by weight of water to the waste oil (step S1). Next, a mixture of waste oil and water, which are raw materials, is poured into the raw material supply port 10 of the atomization processing system (step S2), the raw materials are pressurized by the high-pressure pump 11 and sent to the inlet 14 of the atomization apparatus 12 (step S3) ). Then, using the parent casing 17, the raw material particle size is set to 20 μm (step S 4), the first additional casing 18 a is used, the raw material particle size is set to 1 μm (step S 5), and the second additional casing 18 b is used. Then, the particle size of the raw material is set to 500 nm (step S6), and finally the particle size of the raw material is set to 100 nm or less using the third additional casing 18c (step S7). By this series of processes, mixed emulsification (emulsion) of waste oil and water at the molecular level is generated, and the atomized raw material is taken out from the outlet 15 of the atomizer 12 and accommodated in the receiver 13 (step) S8).

  By following these steps, various waste oils to be discarded can be processed and changed to a high-quality fuel, that is, a desired fuel corresponding to each combustion appliance and apparatus. Therefore, the use of the atomization device 12 of the present invention is beneficial from the viewpoint of energy saving and environmental protection.

  The atomization device 12 of the present invention can be used to process waste oil into a high-quality fuel and to process a liposome serving as a drug storage and transport into a desired size in a drug delivery system. Can also be used.

  The present invention provides an apparatus for atomizing a substance that is excellent in diversification, versatility, simplification, and manufacturability. Moreover, the waste oil which should be discarded can be processed using the atomization apparatus of this invention, and can be changed into a desired fuel, and there exists a benefit from a viewpoint of energy saving and environmental conservation.
