Abstract
The present invention relates to the technical field of chemical industry, and in particular relates to a high-performance fire coal flue gas desulphurisation agent. The desulfurization agent comprises the following components in parts by weight: 20 to 30 parts of activated carbon, 20 to 25 parts of diatomaceous earth, 20-30 parts of quick lime, 5-10 parts of ferric oxide, 1-5 parts of nano titanium dioxide, 5-10 parts of calcium hydroxide, 10-20 parts of calcium carbonate and 5-10 parts of magnesium carbonate. Object of the present invention is to provide a reasonable-formula high-performance fire coal flue gas desulphurisation agent which can reduce environment pollution.
Description
Technical field
The present invention relates to the technical field of chemical industry, specifically a kind of high-performance coal-fired flue gas desulfurization agent.
Background technology
China's energy-consuming is based on coal, it is contemplated that to the year two thousand twenty, and coal production is up to 3,000,000,000 tons. it is estimated that it is 12,000,000 tons that China's atmospheric sulfur dioxide reaches the environmental carrying capacity of national quality secondary standard, and coal fire discharged SO2For years more than 20,000,000 tons, cause China's acid rain and SO2Pollution is on the rise.The controlling soil moist of the sulfur dioxide of current domestic and international application mainly has 3 kinds: burning before desulfurization, burning in desulfurization and burning after flue gas desulfurization.Wherein, flue gas desulfurization is the desulfurization method of currently the only large-scale commercial application, is the technical way controlling sulfur dioxide pollution.
Summary of the invention
It is an object of the invention to be in that to provide the high-performance coal-fired flue gas desulfurization agent that a kind of formula is reasonable, reduce environmental pollution.
The technical solution used in the present invention is, a kind of high-performance coal-fired flue gas desulfurization agent, is made up of by weight following components: activated carbon 20-30 part, kieselguhr 20-25 part, quick lime 20-30 part, iron sesquioxide 5-10 part, nano titanium oxide 1-5 part, calcium hydroxide 5-10 part, calcium carbonate 10-20 part, magnesium carbonate 5-10 part.
It is an advantage of the invention that formula is reasonable, utilize loose structure that activated carbon the has sound response performance coordinated desulfurization to sulfur dioxide, cost is low, significant desulfurization effect, it is to avoid secondary pollution.
Detailed description of the invention
The present invention is further described with the following Examples.
Embodiment 1, a kind of high-performance coal-fired flue gas desulfurization agent, is made up of by weight following components: activated carbon 30 parts, 25 parts of kieselguhr, quick lime 30 parts, iron sesquioxide 10 parts, nano titanium oxide 5 parts, calcium hydroxide 10 parts, calcium carbonate 20 parts, magnesium carbonate 10 parts.
Embodiment 2, a kind of high-performance coal-fired flue gas desulfurization agent, it is made up of by weight following components: activated carbon 20 parts, 20 parts of kieselguhr, quick lime 20 parts, iron sesquioxide 5 parts, nano titanium oxide 1 part, calcium hydroxide 5 parts, calcium carbonate 10 parts, magnesium carbonate 5 parts.
Embodiment 3, a kind of high-performance coal-fired flue gas desulfurization agent, it is made up of by weight following components: activated carbon 25 parts, 23 parts of kieselguhr, quick lime 25 parts, iron sesquioxide 8 parts, nano titanium oxide 3 parts, calcium hydroxide 7 parts, calcium carbonate 15 parts, magnesium carbonate 8 parts.
The preparation method of this desulfurizing agent is first to be pulverized by discarded iron series deoxidizers waste material, after 80-100 order sieves, and filtering and standing layering in water, throw aside clear liquid, precipitate is dried, then according to aforementioned proportion adds each raw material mix and blend, after stirring, namely make finished product.
Should be understood that this embodiment is merely to illustrate the present invention rather than restriction the scope of the present invention.Furthermore, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims protection defined equally.
