Methanol content is Water-In-Oil (Water-in-Oil-O/W) type emulsion more after a little while, and decentralized photo is " water " phase (mixture of water or alcohol and water), and continuous phase is " oil ".Compare oil/water-in-oil emulsion, the energy density of diesel oil, methyl alcohol and water-in-oil emulsion is higher, except having the low advantage of flash temperature, can also eliminate the icing phenomenon when low temperature uses.Because alcohol is oxygenated fuel, the effect that diesel engine burning methanol, water and diesel emulsion liquid have obvious reduction smoke intensity, its smoke intensity drop-out value maximum can reach about 50%.
High-speed stirred emulsifying device mechanical separator speed commonly used at present is high, and consumption of power is big, and intermittent work, and the amount of an emulsification is less, because the restriction of emulsifying manner, the emulsification need of work is accomplished at special emulsification station, then emulsified fuel is offered fuel oil equipment.And emulsifier unit exists defectives such as complex structure, maintenance cost height and emulsifying effectiveness be undesirable.Simple in structure, the convenient operating maintenance of the emulsifying device that the present invention relates to, but also have advantages such as disposal ability is big, emulsify well.
Summary of the invention
The present invention proposes a kind of novel emulsifier unit according to the present defective that emulsifier unit had.This device utilizes the Venturi tube principle, makes diesel oil, first alcohol and water reach the purpose of emulsification.Described Venturi tube comprises entrance, contraction section, throat, diffuser and outlet section, and entrance links to each other with the diesel oil inlet ductwork, and diffuser links to each other with outlet section, and the inlet of first alcohol and water (methanol aqueous solution) is set in the throat of Venturi tube;
The diesel oil of treating emulsification is introduced this Venturi tube from the entrance of Venturi tube, and diesel oil gets into the preceding pressure of Venturi tube greater than 0.48MPa, and the contraction section of the Venturi tube of flowing through arrival throat, flows to diffuser again; The first alcohol and water is controlled at the methanol aqueous solution that forms after the emulsifier between 1%～3% with 1: 1～1: 2 ratio and gross mass content; The pressure of this methanol aqueous solution before getting into Venturi tube is greater than 0.18Mpa; Introduce in the Venturi tube from Venturi tube throat, and mix with the diesel oil at this place that flows through, diesel oil and methanol aqueous solution are with 9: 1～1: 1 mixed of mass flow ratio; Form emulsion, after the diffuser outflow.
Emulsifying agent is meant the mixed liquor of Span of class of department and tween Tween.
Emulsification method involved in the present invention is different from traditional emulsification method.The present invention adds methanol aqueous solution continuously and equably in the diesel oil of continuous-flow and obtains emulsion; This process is with diesel oil and the methanol aqueous solution dynamic process of emulsifying fixed quantity in proportion; Can make methanol aqueous solution be distributed in the diesel oil quickly and evenly at short notice; Avoid local emulsification non-uniform phenomenon, thereby can reduce the unfavorable factor of breakdown of emulsion, prolong the storage life of emulsion.
