Abstract
The invention discloses a coal penetrating agent used for a liquid coal saving agent. The coal penetrating agent is mainly used in coal combustion. The coal penetrating agent is an aqueous solution composed of polymer organic matters and salts, and concretely comprises, by mass, 5-15% of polyoxyethylene sorbitan monooleate, 1-15% of alkylphenol polyoxyethylene, 10-20% of sodium dodecyl benzene sulfonate, 5-10% of sodium citrate, and the balance of water. The penetrating agent aims at different coal species, and the proportions of all substances can be properly adjusted. 0.2% Of the coal penetrating agent is added to the liquid coal saving agent in order to facilitate reduction of the coal saving agent and coal interface resistance and to make effectively components in the coal saving agent fully penetrate into the coal, so the optimum combustion supporting effect of the coal saving agent is reached.
Description
Technical field
The present invention relates to coal combustion additive field, particularly a kind of coal permeate agent be efficiently added in liquid coal-saving agent.
Background technology
Along with the exhaustion day by day of worldwide coal resource, saving and make full use of coal resources is the targets made joint efforts in the whole world.Now because combustion equipment is outmoded, combustion technology falls behind, and the effective rate of utilization of coal is lower, and energy dissipation is comparatively serious, therefore how to improve the emphasis that coal combustion efficiency becomes research.In fire coal, add coal-saving agent, burning of coal efficiency can be significantly improved, thus reach the object of economizing on coal.
Coal-saving agent in the market is mainly divided into solid and liquid two kinds, and solid coal-saving agent is mainly Strong oxdiative thing, because solid-solid blend exists dispersed poor problem, causes the use of solid coal-saving agent to there is larger restriction.Liquid coal-saving agent adopts the mode of directly spraying to mix with coal, its dispersiveness in coal is greatly improved, but owing to there is larger interfacial resistance between liquid coal-saving agent and coal interface, cause liquid coal-saving agent to be difficult to penetrate into coal inside, thus affect the effect of coal saving of coal-saving agent.From Surface Physical Chemistry theory, liquid wants real wetting coal dust to depend primarily on the character of liquid and coal dust itself, therefore, different permeate agents should be adopted to reduce interfacial tension for different coal dust, promote that coal-saving agent infiltrates into coal dust inside, give full play to the effect of component in coal-saving agent.
Add a certain amount of permeate agent in liquid coal-saving agent in the market, but Study and appliance is not carried out to Coal rank, use the blindness that existence is certain.The present invention is from the kind of coal, mating surface physical chemistry knowledge, different permeate agent is investigated, obtain the different permeate agents adapting to Coal rank, coal-saving agent rapid osmotic is conducive to inner to coal dust after adding different permeate agent for Coal rank, thus reach the effect of coal-saving agent, coal dust is burnt from inside to outside.
Summary of the invention
The object of the invention is to the permeate agent that different ratio is provided for Coal rank, make coal-saving agent rapid osmotic inner to coal dust, give full play to the effect of its coal-saving burning.
Know-why of the present invention is: coal causes its surface properties to there is larger difference due to the difference of degree of coalification, and hard coal degree of coalification is high, close structure, and porosity is low, and infiltration is difficulty comparatively, and permeate agent should select lipophilicity stronger.Bituminous coal takes second place due to degree of coalification, and permeate agent should select wetting ability stronger.Brown coal due to degree of coalification low, water content is large, and porosity is high, and seepage force is stronger.
For achieving the above object, the invention provides a kind of coal permeate agent for liquid coal-saving agent, this coal permeate agent is the aqueous solution with macromolecule organic and salt composition, its component and mass percentage thereof are: polyoxyethylene sorbitan acid monoleate 5 ~ 15%, alkylphenol polyoxyethylene 1 ~ 15%, Sodium dodecylbenzene sulfonate 10 ~ 20%, Trisodium Citrate 5 ~ 10%, surplus is water.
According to coal permeate agent of the present invention, when for hard coal, component and the mass percentage of described coal permeate agent are: polyoxyethylene sorbitan acid monoleate 10 ~ 15%, alkylphenol polyoxyethylene 10 ~ 15%, Sodium dodecylbenzene sulfonate 10 ~ 15%, Trisodium Citrate 5 ~ 10%, surplus is water.For hard coal, increase the ratio of polyoxyethylene sorbitan acid monoleate and alkylphenol polyoxyethylene, reduce HLB value, increase lipophilicity, improve osmotic effect.
According to coal permeate agent of the present invention, when for bituminous coal, brown coal, component and the mass percentage of described coal permeate agent are: polyoxyethylene sorbitan acid monoleate 5 ~ 10%, alkylphenol polyoxyethylene 1 ~ 10%, Sodium dodecylbenzene sulfonate 15 ~ 20%, Trisodium Citrate 5 ~ 10%, surplus is water.For bituminous coal and brown coal, increase the ratio of Sodium dodecylbenzene sulfonate, improve HLB value, increase wetting ability, improve osmotic effect.Metal ion in coal-saving agent is carried out complexing as complexing agent by Trisodium Citrate, makes it fully infiltrate into coal dust inside, gives full play to its catalytic combustion-supporting effect.
Present invention also offers the application of above-mentioned coal permeate agent in liquid coal-saving agent, it is characterized in that, the mass ratio according to 2 ‰ when described coal permeate agent uses is added in liquid coal-saving agent, stirs.
Compared with prior art, coal permeate agent of the present invention according to the difference of the degree of coalification of coal, can be selected the proportioning that HLB value is suitable, makes coal-saving agent fully infiltrate into coal dust inside, make it play effect of coal saving.
