Abstract

The invention belongs to the related technical field of internal combustion power fuel oil, and discloses a preparation device of dispersed-phase emulsified oil with an ultrafine particle size. The device comprises an emulsifying tank, a stirring mechanism, an ultrasonic emulsifying mechanism, a sliding mechanism and a temperature control mechanism, the tank body of the emulsifying tank is used for containing liquid to be subjected to micronization treatment, the stirring mechanism is arranged in the tank body, and is used for stirring liquid to be subjected to micronization treatment in the tank body, the sliding mechanism is arranged outside the tank body, is connected with the stirring mechanism, and is used for adjusting the height of the stirring mechanism in the tank body, the ultrasonic emulsifying mechanism is arranged below the tank body and is used for sending ultrasonic waves to conduct ultrasonic high-frequency shearing and smashing on the liquid to be subjected to micronization treatment in the tank body, and the temperature control mechanism is used for regulating and controlling the temperature in the tank body so that the requirements for surfactant activity and precise component content can be met; through the invention, the ultrafine particle size of the emulsified oil is realized, the micro-explosion of spray droplets is favorably realized, the oil-gas mixingis promoted, the combustion efficiency is improved, and the emission of harmful gas is reduced.

Description

technical field [0001] The invention belongs to the technical field related to internal combustion power fuel, and more particularly relates to a preparation device for dispersed phase ultra-fine particle size emulsified oil. Background technique [0002] With the increase in the number of internal combustion engines, energy consumption is also increasing, and with it comes environmental concerns. Carbon monoxide, hydrocarbons, nitrogen oxides, etc. in the exhaust gas of internal combustion power will cause harm to the human body, so alternative fuels and synthetic fuels are gradually being paid attention to. The development of clean alternative fuels for internal combustion power can not only reduce environmental pollution, but also alleviate my country's fossil fuel crisis. As an alternative fuel, emulsified oil can produce micro-explosion in spray combustion, causing secondary breakage of fuel droplets, so that the fuel atomization quality is better and the combustion is...

AI Technical Summary

Problems solved by technology

[0003] At present, many achievements have been made in the preparation of emulsified oil, but there are still the following problems: 1. When the current emulsification device is working, high temperature is often generated, and the increase of emulsified oil temperature will cause the dispersed phase components with lower boiling point to evaporate , thereby affecting the accuracy of the component content of the dispersed phase of the emulsified oil; 2. In the prepared emulsified oil, the particle size of the dispersed phase is large and the particle size distribution range is large, so the emulsified oil has poor stability and cannot be stored for a long time. It is difficult to put into practical use and requires a new preparation method; 3. After the emulsification device is used, it is difficult to drain the emulsion and clean it, which affects the preparation efficiency and the next preparation accuracy
