Abstract

The invention relates to the technical field of additives for coal water slurry, in particular to a coal water slurry additive. The coal water slurry additive comprises, 60-73wt% of a naphthalene-based superplasticizer, 10-18wt% of sodium lignosulfonate, 4-8wt% of sodium metabisulfite, 7-15wt% of caustic soda flake and 2-10wt% of sodium dodecyl sulfate, preferably the coal water slurry additive comprises: 65wt% of the naphthalene-based superplasticizer, 15wt% of sodium lignosulfonate, 5% of sodium metabisulfite, 10wt% of caustic soda flake and 5wt% of sodium dodecyl sulfate. By adding 0.1%-1% of the coal water slurry additive provided by the invention in coal water slurry production, the original dispersing agent, stabilizer and the like can be replaced, no sedimentation or precipitation occurs within 30 days, and the 24h water separating rate can reach less than or equal to 6%.

Description

A kind of slurries additive agent
Technical field
The present invention relates to water-coal-slurry additive technology field, be specifically related to a kind of slurries additive agent.
Background technology
Water-coal-slurry is by a certain percentage, to be passed through Physical Processing by coal, water, additive (including dispersant, stabilizer and auxiliary agent) Processing the novel clean oil-substituted fuel made, slurries additive agent is one of core of COAL-WATER SLURRY TECHNOLOGY, water-coal-slurry of good performance Additive can make water-coal-slurry have higher slurry concentration, the rheological property of shear shinning, good stability and excellent mist Change combustibility, conventional slurries additive agent include lignosulfonates series, humate series, acrylates series, Naphthalene sulfonate series etc., the problems such as the existence of these slurries additive agents is poor to coal and Technological adaptability, pulping effect is undesirable, lack The additive of few function admirable was once constraining the development of China's COAL-WATER SLURRY TECHNOLOGY.
In recent years, although research worker has done substantial amounts of research work both at home and abroad, also has some novel water-coal-slurry additives to develop Come, but these additives to there is cost height, dispersibility, mobility and stabilizing effect not good enough.
Summary of the invention
In order to solve problem of the prior art, the invention provides a kind of slurries additive agent, additive of the present invention can make water-coal-slurry Reach good dispersibility, mobility and stability, be greatly saved the production cost of water-coal-slurry.
Technical scheme of the present invention is as follows:
A kind of slurries additive agent, including naphthalene series high-efficiency water-reducing agent, sodium lignin sulfonate, sodium pyrosulfite, sheet alkali and dodecane Base sodium sulfate, each constituent content is as follows: naphthalene series high-efficiency water-reducing agent 60-73wt%, sodium lignin sulfonate 10-18wt%, burnt sulfurous Acid sodium 4-8wt%, sheet alkali 7-15wt% and sodium lauryl sulphate 2-10wt%.
Preferably: each constituent content of slurries additive agent is as follows: naphthalene series high-efficiency water-reducing agent 65wt%, sodium lignin sulfonate 15wt%, Sodium pyrosulfite 5%, sheet alkali 10wt% and sodium lauryl sulphate 5wt%.
The technical scheme that the present invention provides has the benefit that
Present invention volume 0.1%-1% in water-coal-slurry produces i.e. can substitute original dispersant, stabilizer etc., and 30 days without sedimentation Produce without precipitation, can reach 24 hours syneresis rate≤6%, water-insoluble≤1% of the present invention, selected slurries additive agent Good dependency is had between molecular characterization and ature of coal and coal surface physico-chemical property.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, the present invention is made into one Step ground describes in detail.
A kind of slurries additive agent, including naphthalene series high-efficiency water-reducing agent, sodium lignin sulfonate, sodium pyrosulfite, sheet alkali and dodecane Base sodium sulfate, each constituent content is as follows: naphthalene series high-efficiency water-reducing agent 60-73wt%, sodium lignin sulfonate 10-18wt%, burnt sulfurous Acid sodium 4-8wt%, sheet alkali 7-15wt% and sodium lauryl sulphate 2-10wt%.
Embodiment 1
A kind of slurries additive agent, each constituent content is as follows: naphthalene series high-efficiency water-reducing agent 60wt%, sodium lignin sulfonate 18wt%, Sodium pyrosulfite 8wt%, sheet alkali 7wt% and sodium lauryl sulphate 10wt%.
Embodiment 2
A kind of slurries additive agent, each constituent content is as follows: naphthalene series high-efficiency water-reducing agent 65wt%, sodium lignin sulfonate 15wt%, Sodium pyrosulfite 5%, sheet alkali 10wt% and sodium lauryl sulphate 5wt%.
Embodiment 3
A kind of slurries additive agent, each constituent content is as follows: naphthalene series high-efficiency water-reducing agent 73wt%, sodium lignin sulfonate 10wt%, Sodium pyrosulfite 4wt%, sheet alkali 15wt% and sodium lauryl sulphate 2wt%.
As follows by the test result after the slurries additive agent described in incorporation embodiment 1-3 in coal:
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all the spirit and principles in the present invention it In, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
