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

Embodiment 1

[0054] Span-80 and Op-10 are used as the composite surfactants of water ultra-fine particle emulsified diesel oil in the dispersed phase, and the best hydrophilic-lipophilic balance value HLB is 5-6. The HLB of Span-80 is 4.5, the HLB of Op-10 is 14.5, and the mass ratio of Span-80 and Op-10 is 11.5:1. The emulsified diesel is prepared from the following raw materials in parts by weight: 87.8 parts of diesel, 9.8 parts of deionized water, 2.2 parts of Span-80, and 0.2 parts of Op-10.

[0055] The preparation method of a certain emulsified oil dispersed phase water ultrafine particle size emulsified diesel oil is as follows:

[0056] Add 87.8 parts of diesel oil and 2.2 parts of Span-80 into a beaker and stir until the solution becomes clear; then add 9.8 parts of deionized water and 0.2 parts of Op-10 into another beaker and stir until the solution becomes clear. Pour it into the emulsification tank from the tangential injection port.

[0057] The emulsification temperature ...

Abstract

The invention belongs to the related technical field of internal combustion fuel oil, and discloses a preparation device for emulsified oil with dispersed phase ultrafine particle size. The device includes an emulsification tank, a stirring mechanism, a ultrasonic emulsification mechanism, a sliding mechanism and a temperature control mechanism. The micronized treatment liquid is stirred, and the sliding mechanism is arranged outside the tank, which is connected with the stirring mechanism to adjust the height of the stirring mechanism in the tank. Ultrasonic high-frequency shearing and crushing of the liquid to be finely processed, and the temperature control mechanism is used to regulate the temperature in the tank to make it meet the requirements of surfactant activity and precise component content; through the present invention, the ultra-fine emulsified oil can be realized The fine particle size is beneficial to realize the micro-explosion of spray droplets, promote the mixing of oil and gas, improve the combustion efficiency and reduce the emission of harmful gases.

Description

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