Technical field
The utility model relates to a kind of dehydration and alcoholysis method and equipment of coal, is particularly useful for the dehydration and the alcoholysis collecting process of brown coal under mild conditions.
Background technology
China's lignite resource is abundant, and reserves account for 77% of national brown coal reserves.Because it is higher that most of brown coal contain moisture, in transportation, take a large amount of transport power, consume a large amount of transportation energy.Present still untapped go out effectively the to make practical art of brown coal dehydration and feasible support equipment.
Because water and the organic oxygen in the coal in the brown coal can pass through hydrogen bonded, utilize the fluidized-bed process and the equipment drying and dehydrating of simple physics evaporation, the brown coal after not only consume energy big and the dehydration are difficult to imitate to be preserved; The brown coal that are limited to conceptual phase are heated, high press-dehydrating scheme is considered to energy-conservation technology, but the equipment that mass-producing enlarge to be produced is to be difficult to the problem that solves and realize; By the technology and the rarely seen report of equipment of solvent extraction brown coal dehydration, with 2, the fundamental research that dehydration is carried out to brown coal shows the 2-Propanal dimethyl acetal as solvent, uses boiling point and the higher solvent of price not to possess practicality; Under super critical condition, use methyl alcohol can make the PET carry out optionally pure depolymerization reaction in recent years, but utilize overcritical alcoholysis technology and equipment that the research that brown coal carry out the upgrading utilization is not appeared in the newspapers; " HyperCoal " is one of clean coal technology of developing energetically in the world, but often has problems such as stopping up filter plate in the heat filtering process; Do not see as yet the extraction heat solvend system's separation processes of coal and the report of equipment both at home and abroad so far.
