Problems solved by technology

However, due to various water-mixed combustion methods have their own weaknesses, they cannot improve economic benefits while reducing emissions, and have not been widely used so far.
[0004] The shortcomings of the various existing water-mixed combustion methods mainly focus on the following aspects: Disadvantages of using prepared emulsified diesel oil: first, emulsified diesel oil is forced to mix with water and diesel oil through emulsifier, and oil-water separation will occur after long-term storage, which makes emulsified diesel oil difficult to store and transport; second, the prepared emulsified diesel oil loses Insufficient anti-corrosion performance will cause corrosion of the high-pressure oil nozzle of the diesel engine, so that the oil nozzle cannot inject fuel
Although the on-board emulsification device can dynamically adjust the mixing ratio of water and oil according to the working conditions of the diesel engine, the emulsification effect is not ideal and the emulsified diesel oil will cause corrosion of the high-pressure nozzle of the diesel engine, so that the nozzle cannot inject fuel.
Spraying water directly to the combustion chamber requires installing a nozzle on the cylinder head of the diesel engine, which destroys the structure of the diesel engine itself, although it can reduce NO X and PM soot emissions, but practice has proved that there is almost no fuel-saving effect

Embodiment 1

[0030] The energy-saving and emission-reducing diesel emulsification method disclosed in this embodiment specifically includes the following steps:

[0031] (1) Prepare the emulsifying additive in proportion: the emulsifying additive is mixed by the following raw materials in parts by weight: 0.1 part of potassium nitrate, 0.1 part of potassium bicarbonate, 10 parts of urea, 0.5 part of sodium nitrite, 0.1 part of sodium hydroxide, poly 0.7 parts of vinyl alcohol, 0.1 parts of triethanolamine, 2 parts of Span 80, 0.25 parts of Tween 20, and 100 parts of pure water. Vinyl alcohol, triethanolamine, Span 80, and Tween 20 are poured into the reaction kettle with pure water in sequence according to the ratio, and fully mixed;

[0032] (2) Equipment preparation: such as figure 1As shown, a high-pressure atomizing nozzle 8 is installed on the intake manifold 7 of the diesel engine, and the high-pressure atomizing nozzle 8 is located on the intake manifold 7 of the diesel engine. Th...

Embodiment 2

[0043] Except for the following differences, all the others are the same as in Example 1.

[0044] The energy-saving and emission-reducing diesel oil emulsifying additive of the present embodiment is an emulsifying additive for diesel oil in the prior art, such as the emulsifying diesel oil additive (A-55) of Voerle Science and Technology Enterprise Group.

Embodiment 3

[0046] The energy-saving and emission-reducing diesel emulsifying additive of the present embodiment is formed by mixing the following raw materials in parts by weight: 0.5 part of potassium nitrate, 0.5 part of potassium bicarbonate, 12 parts of urea, 0.1 part of sodium nitrite, 0.2 part of sodium hydroxide, polyethylene 0.75 parts of alcohol, 0.5 parts of triethanolamine, 1 part of Span 80, 0.5 parts of Tween 20, and 100 parts of water.

[0047] The emulsification method of the present application is compared with the diesel oil that has been emulsified, and only sprayed diesel oil without emulsifying additives, namely:

[0048] Group A: The additive composition and formulation are as described in Example 1 of the present application, the diesel emulsification method is also as described in Example 1 of the present application, and the dosage ratio of additives to diesel is 1:5 by weight;

[0049] Group B: Additive components and formulations are as described in Example 1 of...

Abstract

The invention discloses an energy-saving emission-reduction diesel oil emulsifying method. An emulsifying additive and diesel oil are conveyed into a diesel air cylinder separately in sequence, and are atomized in the diesel air cylinder to form emulsified diesel oil. The emulsified diesel oil formed in the diesel air cylinder can be immediately used after mixing is conducted in the diesel air cylinder, residual ash does not exist, the oil-water layering problem is solved, the critical defects that prepared emulsified diesel oil is subjected to oil-water layering after long-time standing, storing and conveying are inconvenient, and a high-pressure oil nozzle is rusted and cannot spray oil in the using process are overcome, and the problem that the prepared emulsified diesel oil cannot be applied and popularized so far is solved.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction, in particular to an emulsification method for energy saving and emission reduction diesel oil. Background technique [0002] With the rapid development of my country's industry, agriculture, and transportation, the demand for diesel is increasing day by day. How to make full use of existing resources, develop energy-saving technologies, and reduce waste has aroused people's great attention. In order to solve the problem of energy shortage and air pollution, energy saving and environmental protection are the key factors to achieve sustainable development at present and in the future. How to reduce fuel consumption and exhaust pollution more effectively is the focus of internal combustion engine research today. In many research projects Among them, water-mixed combustion is considered to be one of the promising technologies to achieve the above two goals at the same tim...
