Fire coal liquid oxidizer for cement production and preparation method thereof

Abstract

The invention provides a fire coal liquid oxidizer for cement production. The fire coal liquid oxidizer comprises the following ingredients: by weight, 20-40% of mineral oil, 25-35% of plant oil, 6-16% of an emulsifier, 4-8% of metal catalyst salt, and the balance water. In comparison with the prior art, the fire coal liquid oxidizer for cement production has the following beneficial effects: on the basis of not changing original equipment and technology, burning point of prepared coal dust is reduced, burning rate is raised and burnout rate is improved; coal consumption per cement clinker is decreased, discharge capacity is minimized, energy is greatly saved, sintering of cement clinker is promoted, quality of cement clinker is raised, and economic and social benefits of cement clinker production are enhanced; and the fire coal liquid oxidizer is beneficial to environmental protection. The invention also provides a preparation method of the fire coal liquid oxidizer.

Description

technical field [0001] The invention relates to the field of pulverized coal combustion, in particular to a coal-burning liquid combustion enhancer for cement production and a preparation method thereof. Background technique [0002] In the field of cement production, many enterprises still use coal as the main energy source in the clinker burning process. In recent years, as countries all over the world attach great importance to environmental protection, people pay great attention to this traditional production method that is easy to cause environmental pollution. [0003] On the other hand, improving fuel utilization to achieve energy saving and cost reduction is the constant pursuit of cement production enterprises. In fact, energy saving can not only reduce costs, but also means reducing emissions. That is to say, if effective energy-saving technologies can be adopted, corresponding environmental protection effects can be obtained. [0004] In enterprises that use pul...

Problems solved by technology

[0008] The development of coal-fired combustion aids has a history of decades. Traditional combustion aids mainly use mixtures of alkali metals, alkaline earth metals, and transition element metal salts as catalysts. This kind of coal-fired combustion aids has the following disadvantages: large amount of addition , even up to 5% of the amount of raw coal, that is, the amount of combustion improver added to one ton of raw coal reaches 50 kg; the cost performance is low; alkali metals, chloride ions, and sulfur elements often exceed the standard; the corrosion of combustion equipment is serious; and it is difficult to transport
