Description

A kind of Compositional type slurries additive agent
Technical field
The present invention relates to coal gasification commercial Application, in particular to a kind of cheap, efficient, cost-effective Compositional type Slurries additive agent.
Background technology
China is the country of the rich few oil of coal, and rich coal resources account for about the 70% of domestic energy consumption.The biography of coal Application method lime-ash of uniting is more, pollution is big, transport difficult and expensive, burning and heating efficiency be not high.Water-coal-slurry is a kind of use The environmental clean fuel of New type coal base flow body and a kind of coal prepared by physical method does the novel original of raw material production synthesis gas Material.The technology passes through to coal resources deep processing, rationally using improving the utilization rate of coal resources.
In water-coal-slurry raw material production cost, other than 60%~70% coal and 30%~40% water, water-coal-slurry is improved The slurries additive agent of performance constitutes the second largest cost factor of water-coal-slurry.Slurries additive agent is to the viscosity of water-coal-slurry, dense The key indexes such as degree, stability and mobility suffer from directly influencing, so, reduce the use of slurries additive agent into This, improving effective utilization becomes a key subject of current COAL-WATER SLURRY TECHNOLOGY.
At present, domestic and international slurries additive agent is broadly divided into two major class of anionic and neutral ionic.By its chemical group Into difference, be divided into for:Naphthalenesulfonate formaldehyde condensation compound, lignosulfonates, humate, polycarboxylic acids, polyolefin, aliphatic poly Close object, polyethers and long-chain alcohol ketone derivatives etc..
Different slurries additive agents disperses viscosity reduction ability, slurry concentration, mobility and stability to same coal Effect is different.All in all, anionic slurries additive agent-naphthalenesulfonate formaldehyde condensation compound that the country largely uses at present Its dispersion performance, slurry mobility are preferable, applied widely, however slurry stability is poor, and due to producing naphthalene sulfonate The higher price of raw material-naphthalene of formaldehyde condensation products, the cost price for leading to naphthalenesulfonate formaldehyde condensation compound is higher, a large amount of to use Cause production cost higher so that the slurries additive agent competitiveness of naphthalenesulfonate formaldehyde condensation compound class declines.Lignin sulfonic acid For salt compared with naphthalenesulfonate formaldehyde condensation compound, price advantage is apparent, and raw material resources are enriched and are easy to get, and slurrying stability compared with It is good.But the complicated component and performance due to the lignin as raw materials for production are unstable, lignosulfonates it is slurry Performance is also unstable, it is difficult to meet commercial Application requirement.Humate is extracted from low price coal, and dispersion performance is preferable, but It easily forms precipitation, the stability of slurry is very poor to metal ion-sensitive.Polycarboxylic acids, aliphatic polymer, gathers polyolefin Ethers and long-chain alcohol ketone derivatives are according to the difference of its molecular weight, and using effect is different, and all in all, effect is better than Naphthalenesulfonate formaldehyde condensation compound, lignosulfonates and humate, but due to strictly to control molecular weight and at high price, It cannot be widely used to promote.
China's slurries additive agent type currently in use is various at present, and quality is irregular, cost performance it is not high or Efficiently at high price or cheap performance is bad, it is difficult to meet increasingly competitive industrialization development.In addition, with environmental protection Pressure increases, often with the buck of gasification system, steam condensate (SC), other process units during coal water slurry gasifying device slurrying It produces one or more of waste water, biochemical water, alkali waste water etc. and partly or entirely replaces technique desalted water, considerably increase water coal The slurrying difficulty of slurry.The slurries additive agent of single use a certain kind component can not meet the development of coal water slurry gasifying device It is required that therefore, we must develop a kind of higher high ecad Compositional type slurries additive agent of sexual valence, to cope with water-coal-slurry The increasingly complicated operating mode of gasification installation pulping system, improves water coal slurry concentration, reduces viscosity of coal slurry, improve water-coal-slurry mobility, Expand gasification slurrying coal range.
