Abstract

PURPOSE:To obtain a small mixing apparatus easily installed and having excellent mixing capacity, by providing a partition plate having plural holes concentrating fluids after passing to one point in a fluid passing pipe. CONSTITUTION:A partition plate 12 is provided in a pipe 10 passing fluids to be mixed but, in the vicinity of the outer periphery thereof, plural holes formed by drilling are provided so as to direct the fluids toward the center of the pipe 10 and to concentrate the same after passing to one point. When fluids are injected from the holes 14 of the partition plate 12, they are formed into jet streams and these streams are mutually impinged to be formed into fine particles and similar operation is repeatedly carried out at the next partition plate. As described above, a small mixing apparatus easily installed and having good efficiency is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixing device for mixing and emulsifying a plurality of fluids, particularly water and oil.

When oil is mixed with 5 to 20 parts of water to form an emulsion and burned, the water particles vaporize explosively and scatter the oil, which has a circumference of C2, so the oil becomes extremely fine particles and burns. Therefore, combustion efficiency is improved, and the amount of nitrogen oxides and soot in the exhaust gas can be reduced. As the oil and water mixing device used to carry out this combustion method, a stirring type device has conventionally been generally used. However, the stirring type apparatus has a disadvantage in that a sufficiently small emulsion cannot be formed due to the large lid and mixing time required.The present invention is intended to eliminate these disadvantages.

The present invention will be explained according to the embodiments shown in the figures.

10 is a tube through which the fluid to be mixed passes. This fluid flows from left to right in FIG. Reference numeral 12 denotes partition plates, of which six partition plates are provided inside the pipe IO.

Four pores 14 are located near the outer periphery of this partition plate 12, and the center
The pores are oriented so that the fluid ejected through the pores is concentrated in one point. 16 is a joint attached to both ends of the pipe 10.

When a pressurized fluid to be mixed is poured into this pipe lO from the joint 16 at the left end in FIG.
A jet stream is ejected from 4, and these jet streams collide with each other. At this time, the particulate portion consisting of a single component in the fluid is destroyed and becomes minute particles.

Further, the fluid is mixed by extremely irregular vortices C2 generated by this jet flow. This mixed fluid is applied to the next partition plate l! The water is ejected from the pores 14 and mixed in the same way.

In the above example, the diameter of the pores 14 was ft4 and the thickness of the partition plate 12 was t' 7 ms in apparatus C2. When heavy oil containing 20% water was pressurized to 4 atm and added, the water directly v
An emulsion of k3 to 20μ was obtained.

In the above embodiment, six partition plates 12 are used, but an appropriate number may be used as necessary. It is also possible to circulate the fluid and place this device in its path. In this way, the fluid passes through the partitions many times, and an excellent mixing effect can be obtained even with a device using a small number of partitions. The size, number, etc. of the pores 14 may be appropriately selected depending on the required supervision.

The mixing device of the present invention is small and tubular, so it is easy to install and has excellent mixing ability. Therefore, it is suitable for mixing oil and water used in the above-mentioned combustion method, but it also has the characteristic that it can be used for mixing a wide range of seed fluids.
