What harm does emulsified oil do to people

Emulsified oil can be used for some commercial purposes, mainly hydraulic supports, which can provide support, lifting, movement, etc. However, if the human body is in contact with it for a long time, some chemical reactions will occur, and adverse symptoms will occur after being inhaled by the human body. Therefore, everyone should pay attention to the great harm of emulsified oil in daily life, and need to understand it clearly and take precautions.

Main Application

Emulsified oil is mainly used in hydraulic supports in fully mechanized mining working faces. Hydraulic support is one of the key equipment in the comprehensive mining working face. It is composed of columns, cylinders, top beams, bases, various control valves and pipelines. Its support, lifting, movement, pushing and overload protection all rely on pressurized liquid - high-water content hydraulic fluid, which flows in a system composed of pipelines and control elements with a certain structure to achieve energy transfer and conversion.

Performance Analysis

Emulsification by dedicated equipment

Emulsified oil is usually made by adding 70% to 90% of fuel (gasoline, diesel or heavy oil) to 30% to 10% of water (mass ratio).

Ratio, the same below), then add 0.5%~1% additives, and then emulsify through special equipment. The oil becomes an oil-in-water type molecular group, the particles of which are generally 0.5~10 μm. The smaller and more uniform the particles are, the longer the stability period of the emulsified oil is, generally 1~6 months. The oil-water separation of the emulsified oil is called demulsification, and after demulsification, it will lose its performance.

The physics of the combustion process

The physical effect of the emulsified oil combustion process is the so-called "micro-explosion" theory. Oil-in-water type molecular group, oil is the continuous phase and water is the dispersed phase. Since the boiling point of oil is higher than that of water, water always reaches the boiling point first and evaporates or boils when heated. When the pressure in the oil droplets exceeds the sum of the surface tension of the oil and the ambient pressure, the water vapor will break through the resistance of the oil film and cause the oil droplets to explode, forming smaller oil droplets. This is called micro-explosion or secondary atomization. The tiny oil droplets after the explosion are more likely to burn. Therefore, the oil burns more completely, making the internal combustion engine or oil furnace achieve energy saving effect. The chemical reaction is the water-gas reaction. Many documents point out the importance of water-gas reaction when discussing the reasons why emulsified oil saves energy and reduces pollution. Under oxygen-deficient conditions, the carbon particles produced by high-temperature cracking in the fuel can react with water vapor to generate CO and H2, allowing the carbon particles to burn fully, improving the combustion rate and reducing the smoke content in the exhaust gas. According to testing by the environmental protection department, the smoke density can be reduced by 50%.

Dual effects of reducing air pollution and saving energy

Through the above-mentioned micro-explosion and water-gas reaction, emulsified oil fuel can achieve the dual effects of reducing air pollution and saving energy. But there are conditions for obtaining this dual effect. For example, when a diesel engine uses emulsified diesel, the evaporation rate of the oil droplets is suppressed under high pressure conditions in the cylinder, thus extending the evaporation time of the oil droplets. The water in the oil droplets continues to evaporate during this time, and the intensity of the micro-explosion is relatively weakened. From the perspective of micro-explosion, it is impossible for a diesel engine to achieve significant fuel savings. However, it is easy to be satisfied under the condition of oxygen deficiency in the cylinder, which creates conditions for the water-gas reaction. The operation experiment of emulsified diesel in diesel engine proves that in addition to the effects of energy saving and pollution reduction, the cylinder is not corroded, worn or carbonized, and its power performance remains basically unchanged. For example, atmospheric pressure industrial boilers have the dual conditions to produce micro-explosion and water-gas reaction, so the use of emulsified heavy oil in atmospheric pressure industrial boilers can achieve good results.
