Problems solved by technology

my country's coal-fired market is in urgent need of desulfurization technology and equipment. However, due to the huge one-time investment and heavy economic burden, the promotion and application of desulfurization devices is limited to a certain extent. There are only a small number of applications in large-scale coal-fired projects in my country. The small-scale coal-fired market needs desulfurization technology and equipment with small one-time investment, good effect and low cost

Embodiment 1

[0057] Embodiment 1: environment-friendly, coal-saving, sulfur-removing and dust-reducing emulsion, its composition weight ratio is successively distilled water 75.9%, maleic acid di-secondary octyl sodium 0.4%, light hydrocarbon 2.5%, sodium tetraborate 0.3%, 15% of sodium nitrate, 3% of sodium chlorate, 0.5% of sodium peroxide, 1% of sodium dichromate, 1% of sodium carbonate, and 0.4% of ammonium perchlorate are successively added to the high-speed stirring reaction kettle for heating and carrying out compound reaction, and then Enter the high-speed jet pulverizer for shearing and reciprocating cycle shearing and crushing, and mix a stable emulsion-like environmental protection coal-saving, sulfur-removing and dust-reducing agent. When using it, add water at a ratio of 1:10, and mix 11% emulsion-water mixture per ton of raw coal for use. When the temperature is increased by 130°C, the blackness of the flue gas is reduced by 1 Ringelmann level, the coal saving rate reaches 10%...

Embodiment 2

[0058] Embodiment 2: environment-friendly, coal-saving, sulfur-removing and dust-reducing emulsion, its composition weight ratio is successively distilled water 66.2%, maleic acid di-second-octyl sodium 1.0%, light hydrocarbon 3.5%, sodium tetraborate 0.4%, 18% of sodium nitrate, 4% of sodium chlorate, 1% of sodium peroxide, 2.5% of sodium dichromate, 2.0% of sodium carbonate and 1.4% of ammonium perchlorate are added successively to the high-speed stirring reaction kettle for heating and carry out compound reaction, and then Enter the high-speed jet pulverizer for shearing and reciprocating cycle shearing and pulverization, and mix a stable emulsion-like environmental protection, coal-saving, sulfur-removing and dust-reducing agent. When using, add water at a ratio of 1:10, add 11% emulsion water mixture to each ton of raw coal, increase the furnace temperature by 150°C, reduce the blackness of flue gas by 2 levels, save coal by 15%, and reduce sulfur dioxide emissions Volume...

Abstract

This invention relates to an environmental protection coal-saved sulphur-remove and dust-reducing emulsion. Taking the weight percentage as one unit, 25%-75% weight portion of distilled water is added into a reaction kettle to be mixed and heated to 60-80deg.C then 0.1-1.5% weight portion of a malcate and 0.1~5.5% of light hydrocarbon are added and mixed at high speed for 15-35min to keep the temperature, then 0.1-0.5% portion of sodium tetraborate, 0.1~20% of sodium nitrate, 0.1~5% of sodium chlorate, 0.1~2.5% of sodium dioxide, 0.1~5% heavy sodium chromate and 0.1~3.5% ammonium perchlorate are added into the kettle to carry out chemical reaction and mix for 15-30min then enters into a high speed jet crushing machine to cut them repeatedly for 3-5times.

Description

technical field [0001] The invention relates to an environment-friendly coal-saving, sulfur-removing and dust-reducing emulsion and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the world's energy crisis continues, my country's coal consumption continues to increase, and the emission of sulfur dioxide from coal combustion is also increasing. For many years, my country's coal consumption has exceeded 20 million tons, resulting in increasingly serious atmospheric acid rain and sulfur dioxide pollution. The area affected by acid rain has accounted for 30% of the country's land area, and the frequency of acid precipitation in central China exceeds 90%. The direct economic losses caused by sulfur dioxide to my country's national economy have accounted for 2% to 3% of GDP, which has had a great impact on the healthy development of my country's national economy. For the strategic goal of sustainable development of m...
