Description
Technical field
The present invention relates to the purge of sulfide in a kind of elimination civilian (combustion) coal or claim additive, specifically is a kind of desulfurized composition for civil coal.
Background technology
At present, China uses in town and country civilian coal to cook and particularly warms oneself by a fire winter etc., and is still very general.But as the saying goes not coal-forming of no sulphur, because coal is the sulfur-bearing thing, so, the sulfurous gas sulfides that civilian coal produces when burning brings very big harm for people's health and life: one, the sulfurous gas sulfides that civilian coal in the coal stove produces when burning gives out the bad smell (stink) of pungent dotting punch, make and cook and the people that warm oneself by a fire that reunite are difficult to stand, especially long-term old and weak person in the kitchen can't bear the heavy load especially, it can cause people's keratitis, shed tears, symptoms such as cough, when serious even cause feeling sick, vomiting, dizziness etc., if things go on like this, the health to people causes great injury.Two, the sulfide of civilian coal generation when burning has very big corrosion failure effect to cooker, and all iron pans that uses on coal stove, aluminium kettle, Stainless steel basin etc. are easy to occur delamination and wear phenomenons such as the end, are subjected to very big influence its work-ing life.Three, the sulfide that produces in when burning of civilian coal also brings very big erosion damage to upholstery furniture etc., returns black etc. such as wall flavescence, furniture variable color, decorative sheet.Four, deposit after existing civilian coal is carried out when to be burnt, also send a kind of smell of not smelling good.Five, it is saturating that existing civilian coal generally can not make its combustion of burnouting fully of coal cinder such as honeycomb briquette, but leave a small amount of residual coal.Though sulphur content can not surpass 1% in the civilian coal of national regulation, the actual sulphur content in the civilian coal is often more than 2%.Even be controlled in 1%, more than harm is still exist actually, if exceed standard, its harm then more becomes serious.
And according to the knowledge of the applicant, at home and abroad there is no the report of the desulfurized composition for civil coal of the sulfide in the time of really effectively eliminating civilian coal combustion at present.Proposed a kind of energy-conservation falling as someone once and dye the combustion additive, but its sulfur limitation effect is very little in the practice with potassium permanganate 2%～5%, sodium-chlor 80%～90%, yellow soda ash 3%～10%, and cost more expensive (about 4 yuan of per kilogram).
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defective of above prior art, and a kind of desulfurized composition for civil coal of the sulfide can effectively eliminate civilian coal combustion the time is provided.
Technical solution of the present invention provides a kind of desulfurized composition for civil coal of being made up of following materials based on weight: calcium oxide 50～90, Potassium Iodate 1～4, sodium-chlor 7～13, ferrous sulfate 3～7, rice-straw ash 8～15.Described calcium oxide refers to the calcium oxide that bulk storage (comprises 20 days) at the moistureproof place that ventilates more than 20 days, and the purpose of doing like this is to distribute the smell of calcium oxide itself.
The preferred weight umber of above raw material is: calcium oxide 60～80, Potassium Iodate 2～3, sodium-chlor 8.5～11.5, ferrous sulfate 4～6, rice-straw ash 9～12.
The optimum weight umber of above raw material is: calcium oxide 70, Potassium Iodate 25, sodium-chlor 10, ferrous sulfate 5, rice-straw ash 10.
Described calcium oxide has another name called calcium lime powder (Powdered), and molecular formula is CaO.The dehydration of the drying of on the existing publication material being tended in the character and the effect of calcium oxide, alcohol, the additive of making fertilizer and sterilant, sterilant aspect.And ignored the leading role of calcium oxide sulphur removal, even in chemistry and chemical industry complete works, there is not the record of calcium oxide desulphuration in coal yet.
The molecular formula of described Potassium Iodate is KIO
3Introduction to its effect in the existing publication mainly is medical discutient and makes iodic salt etc.The present invention adopts commercially available pulverous Potassium Iodate.
Described sodium-chlor is salt, and molecular formula is NaCl.Existing publication introduction is mainly seasonings and sanitas, also is used to make dyestuff, glass etc., and anti-inflammatory, combustion-supporting effect are arranged.The present invention adopts commercially available pulverous salt.
Described ferrous sulfate, molecular formula are FeSO
4Existing publication introduction can be done fire coal and water purification agent, certain desulphuration is arranged, but price is expensive, if heavy dose of the application, its cost is too high.The commercially available Powdered crystalline ferrous sulfate that the present invention adopts plays auxiliary sulphur removal.
Described rice-straw ash refers to the ash that its straw burns till behind the paddy rice degrain.It contains alkalescence, mainly works to eliminate peculiar smell.
Raw material with above parts by weight during production stirs according to a conventional method, is packaged into bag with plastics bag etc. and gets final product, and is generally 1000 gram/bags (1kg/ bag).
During use, this composition is admixed to stir in the base-material of the honeycomb briquette that the civilian coal, earth of known technology and coal consumption of living that water is formed do not wait with size diameter as life get final product this composition of adding 1kg in the above-mentioned base-material of the general every 300Kg of its consumption.
Desulfurized composition for civil coal of the present invention has following remarkable advantage and beneficial effect.
One, the applicant gropes practice through for many years, invent out this desulfurized composition for civil coal, wherein take composition as the leading factor with calcium oxide, it has the special efficacy of removing sulfurous gas sulfides in the civilian coal, be aided with Iron sulfuret, utilize the smoke abatement of Potassium Iodate, rice-straw ash and sodium-chlor to eliminate the unusual smell and the disinfectant function again.This composition has the best effect of sulphur removal when civilian coal combustion, has eliminated the sulfurous gas sulfides brings human body, kitchen utensils, furniture, indoor environment etc. when burning in the civilian coal harm and destruction fully.Through confidentiality admix in the civilian coal through tens tame civilian coal users and use and suggestion feedbacks, all confirm to admix the civilian coal such as the honeycomb briquette of this composition, when burning, eliminated the bad smell of the pungent dotting punch that the sulfurous gas sulfides gives out in the civilian coal fully.And through nearly 1 year tracking investigation, all uses are mixed with the user of the civilian coal of this composition, all do not occur because of symptoms such as sulfide produces keratitis, sheds tears, coughs again, more do not find because of phenomenons such as feeling sick of causing of sulfide, vomiting, dizzinesses.Do not occur delaminations such as iron pan, aluminium kettle, Stainless steel basin more yet and wear corrosion phenomenons such as the end.Upholstery furniture etc. does not occur wall flavescence, furniture variable color, decorative sheet more yet and returns phenomenons such as black.And also not having any bad smell again in the depositing before this coal combustion distributes.
