Problems solved by technology

After sulfur dioxide is oxidized in the atmosphere, it will form sulfate aerosol, and its toxicity can be increased by more than 10 times, which can cause cough, chest tightness, eye irritation, dyspnea, etc. Plant growth; and acid rain produced by sulfur dioxide will reduce soil fertilizer efficiency and damage soil structure
Among them, pre-combustion desulfurization can remove 45% to 65% of inorganic sulfur, and organic sulfur is not easy to remove; sulfur fixation in combustion is convenient and easy, with less investment and low operating costs, but there i...

Abstract

The invention discloses a multifunctional liquid efficient fuel-coal sulfur-fixing agent and a preparation method thereof. The multifunctional liquid efficient fuel-coal sulfur-fixing agent comprises lanthanum oxide, cerium oxide, vanadium oxide, nano-titanium oxide, nano-zinc oxide, nano-nickel oxide, nano-calcium carbonate, nonylphenol polyoxyethylene ether, octylphenol polyoxyethylene ether, fatty alcohol-polyoxyethylene ether, oily penetrating agents, polydiethylene glycol monooleate, glycerol, polymeric glycol, propylene glycol polyoxyethylene polyoxypropylene ether, dimethyl polysiloxane polyether, dehydration sorbitol monooleate and the balance diethylene glycol. According to the technical scheme, yttrium oxide, aluminum acetylacetonate and polyoxyethylene ether are added. The sulfur-fixing efficiency of the multifunctional liquid efficient fuel-coal sulfur-fixing agent can reach 99% or more, the denitration efficiency of the sulfur-fixing agent can reach 50% or more, the combustion rate and the burn-off rate of coal can be sufficiently increased, the ignition point of the coal is remarkably reduced by 50 DEG C or more, the combustion efficiency of the coal is improved by 25% or more, so that combustion environments are reasonably improved, and boiler coking is prevented and removed.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, relates to a coal-fired nano-catalytic sulfur-fixing technology, and in particular relates to a liquid multi-functional high-efficiency coal-fired sulfur-fixing agent and a preparation method thereof. Background technique [0002] my country is a country rich in coal, poor in oil and less in gas, which determines the dominant position of coal in my country's primary energy structure. In 30 years, the energy structure will still be dominated by coal, and the annual coal consumption by combustion accounts for more than 80% of the total coal consumption. [0003] Sulfur dioxide and nitrogen oxides produced by burning coal are discharged into the atmosphere, causing serious pollution to human beings and the ecological environment. At present, my country's annual emissions of S0 2 More than 20.9 million tons, of which 90% of sulfur dioxide comes from burning coal. T...
