Abstract
The invention relates to a gas film coke quenching additive which is prepared from a foaming agent, a foam stabilizer and a film forming agent by mixing according to a certain ratio and uniformly stirring, wherein the foaming agent includes an inspiratory foaming agent and a foaming agent capable of spontaneously generating gas through reaction; the foam stabilizer mainly includes proteins, water-soluble polymer compounds and synthesized surfactants; and the film forming agent is a material capable of forming a passivation film on the coke surface. When the gas film coke quenching additive is dissolved in water to prepare a 0.01 to 1% solution as the substitute of common water for coke quenching, the solution, on one hand, can form a gas film on the coke surface to prevent the coke from being damaged by water, which is equivalent to coke dry quenching, meanwhile, the water is prevented from directly contacting with the coke due to the isolation effect of the gas film so as to greatly reduce the amount of the generated steam; on the other hand, a passivation film is formed on the coke surface, thus greatly improving the coke quality and remarkably reducing the discharge of harmful steam, which is conducive to environmental protection.
Description
Technical field
The invention belongs to the coking technology field, is a kind of coke quenching water additive that is used for the water quenching.
Background technology
Present coke quenching method has dry coke quenching and water quenching, and dry coke quenching has the coke quality of raising, effect in energy saving and environmental protection, is a kind of advanced person's quenching technology, but owing to high facility investment and running cost can't generally be promoted in non-developed country.The water quenching is present most widely used quenching technology, its advantage is that equipment manufacturing cost is low, running cost is low, shortcoming is that the coke quality of quenching is poor, also produce the harmful steam row heavenwards that contains dust, benzene, phenol, prussiate, sulfide in a large number simultaneously, cause huge environmental pollution and thermal pollution.Though the technology of passivator such as adding boron-containing compound, silicon-containing compound, Graphite Powder 99 in coke quenching water is arranged at present, and these passivator only can improve the thermal characteristics of some coke, still are powerless in others.
Summary of the invention
The objective of the invention is: a kind of air film coke quenching additive agent is provided, it is dissolved in to be mixed with concentration in the coke quenching water be 0.01～1% the aqueous solution, substitute the ortho-water quenching with this aqueous solution again, then can increase substantially coke quality on the one hand, reduce the coke water ratio; Can reduce the quantity discharged of harmful steam on the other hand again significantly.
Air film coke quenching additive agent of the present invention is composed as follows: it is made up of whipping agent, suds-stabilizing agent and membrane-forming agent, and it is that whipping agent, suds-stabilizing agent and membrane-forming agent are mixed in proportion the mixture that forms.Its ratio is a whipping agent: suds-stabilizing agent: membrane-forming agent=100:(1～30): (1～50).
Whipping agent comprises that air-breathing property whipping agent and reaction are from the gas-forming property whipping agent, air-breathing property whipping agent comprises natural glue and their derivative (as sylvate), tensio-active agent, tensio-active agent comprises anion surfactant, cats product again, nonionogenic tenside, amphoterics, polymeric surface active agent and special surface active agent; Reaction comprises azo-compound, aminated compounds, ammonia salt and carbonate from the gas-forming property whipping agent.
That suds-stabilizing agent comprises is protein-based, water-soluble polymer class and contain amino, amido, hydroxyl, carboxyl, carbonyl, ester group and ether etc. and have the synthetic class tensio-active agent (as fatty acid methyl alcohol amide, acetyl amino dodecane, Ninol etc.) that generates the hydrogen bond condition, and water-soluble polymer comprises natural family macromolecule (starch based, seaweeds, natural glue class and microbiological gum) again; Semi-synthetic family macromolecule [improving cellulose family (as carboxymethyl cellulose, methylcellulose gum, cyanoethyl cellulose etc.), modified starch series (cationic starch, carboxymethyl starch etc.)]; Synthetic class organic polymer [polymer resin (as polyacrylamide, polyvinyl alcohol, polyoxyethylene glycol etc.), water-soluble condensed cluster resin (polyamine fat, Resins, epoxy, resol, aminoresin etc.)].
Membrane-forming agent comprises carbon black, Graphite Powder 99, silica flour, alkane and its derivative, aromatic hydrocarbons and its derivative.
At whipping agent, among three classifications of suds-stabilizing agent and membrane-forming agent, sometimes a kind of compound or material can play three kinds of effects (fragrant hydrochlorate) simultaneously, and a kind of sometimes compound or material can play two kinds of effects (be whipping agent, be suds-stabilizing agent again as lauryl alcohol) simultaneously, and what have can only play a kind of effect.
The compound method of air film coke quenching additive agent of the present invention is as follows: with whipping agent, suds-stabilizing agent and membrane-forming agent by 100:(1～30): the mixed of (1～50) stirs.The material that has (as arene salt) but the time spent play 2～3 kinds of effects, several materials of the need that have mix just tool reinforced effects, so the concrete component of air film coke quenching additive agent of the present invention can only contain a kind of material (or compound).Also can nearly contain tens kinds of materials (or compound).During use, be that 0.01～1% the aqueous solution promptly can be used for quenching with the additive that the processes concentration that is mixed with soluble in water.
The advantage that air film coke quenching additive agent of the present invention is applied to quenching is: (1) improves coke quality, M
40Improve 2～6%, M
10Reduce by 0.5～4%, CSR improves 3～10%; (2) water content (below 1%) of reduction coke; (3) reduce harmful discharge of steam, its discharge of steam amount is lower than more than 50% of ortho-water quenching.
Embodiment
Embodiment 1: with alkyl benzene sulphonate (ABS) ammonium and Ninol with the mixed of 10:1 stir one embodiment of the present of invention.
Embodiment 2: dodecyl methyl ammonium chloride, polyvinyl alcohol, carbon black evenly are dissolved in water again with the mixed of 10:1:1 are an alternative embodiment of the invention.
Embodiment 3: a kind of raw material of Sodium dodecylbenzene sulfonate also be can be used as one embodiment of the present of invention, because Sodium dodecylbenzene sulfonate has the effect of whipping agent, suds-stabilizing agent and membrane-forming agent simultaneously.
Claims (2)
1. air film coke quenching additive agent, be to mix in proportion the mixture that forms by whipping agent, suds-stabilizing agent and membrane-forming agent, its ratio is a whipping agent: suds-stabilizing agent: membrane-forming agent=100: (1～30): (1～50) is characterized in that described whipping agent adopts one or both in alkyl benzene sulphonate (ABS) ammonium, the Sodium dodecylbenzene sulfonate; Suds-stabilizing agent adopt in polyvinyl alcohol, aminoresin, the Ninol a kind of, two or three; Membrane-forming agent adopt in carbon black, the black powder of stone, the silica flour a kind of, two or three.
2. the application of the described air film coke quenching additive agent of claim 1 is to be 0.01～1% the aqueous solution with the described additive of claim 1 concentration that is mixed with soluble in water, is used for quenching.
