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

preparation example Construction

[0031] A preparation device for preparing dispersed phase ultra-fine particle size emulsified oil comprises an emulsification tank, an ultrasonic emulsification mechanism, a stirring mechanism, a sliding mechanism and a temperature control mechanism.

[0032] like figure 1shown, wherein the emulsification tank includes a semicircular tank cover 1 and a tank body 4, a tangential liquid injection port 2 is opened above the semicircular tank cover 4, and a stirring motor support base 3 is arranged in the center; There is a female rotary LTR type ball spline 301 and a sealing ring 302; one side of the tank body 4 is provided with a connected liquid level gauge 5 to observe the height of the emulsion in the tank, which can be used as a reference for setting the displacement range of the slider 16. A liquid outlet 7 is set on the side to collect the emulsion and discharge the waste liquid, and the bottom is provided with an inclined iron plate baffle 8 inclined at 3 to 5° to ensure ...

Embodiment 1

[0054] Span-80 and Op-10 were used as dispersed phase water ultra-fine particle emulsified diesel composite surfactants, and the optimum hydrophilic-lipophilic balance HLB was 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 oil was prepared from the following raw materials in parts by weight: 87.8 parts of diesel oil, 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 ultra-fine particle emulsified diesel oil is as follows:

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

[0057] The emulsification temperature is set to 20-35℃, and the speed of the sti...

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...
