Description
Technical field
The present invention relates to the preparing technical field of coal adhesive, be specifically related to a kind ofly improve tackiness agent of Filter Tuber For Clean Coal hot strength and preparation method thereof.
Background technology
In the combustion processes of Industrial Boiler, industrial furnace and producer gas generator, the hot strength of moulded coal (coal briquette, coal rod) is also a key index.At the temperature of 950 ~ 1250 DEG C, the normal operation impact of melt flow point on stove and accessory of moulded coal is fairly obvious, and boiler, industrial furnace in combustion, require that moulded coal becomes civilized and do not fall apart, thus impel the vaporization rate or combustion-supporting burning completely or improve moulded coal.In combustion processes, producer gas generator then requires that moulded coal can form skeleton function.The coal ash fluxing point that moulded coal is too low, then cause melt flow at a certain temperature, thus cause the phenomenon such as furnace, slagging scorification, very large on the normal operation impact of stove and accessory.Therefore, enough attention to be had to the moulded coal utilizing coal dust to make (coal briquette, coal rod) hot strength.
At present, the tackiness agent for industrial shaping coal is of a great variety, can divide three major types in a broad sense: organic, complex class and mineral-type.Organic tackiness agent mainly contains tar, pitch, humic acid etc., and Problems existing needs heat fused, has pungency, easily causes secondary pollution; The adhesives ability of complex class is strong, have certain calorific value, but its thermal stability is poor; Mineral-type tackiness agent is as materials such as clay, wilkinite or kaolin, it is cheap, cohesiveness is strong, but its shortcoming to make type pit ash increase after adding, thermal value reduces, and these materials are all almost incombustible materials, and excessive adds, affect the fixed carbon content of moulded coal itself, and the thermostability of coal is also had a certain impact.
Summary of the invention
The object of this invention is to provide a kind of high-heat strength Filter Tuber For Clean Coal tackiness agent and preparation method thereof, tackiness agent of the present invention joins in Filter Tuber For Clean Coal, make shaping after, the hot strength of coal briquette can be improved, do not increase moulded coal ash content, and it is simple to have production process, efficiency is high, the advantages such as quality product is high, non-secondary pollution.
In order to achieve the above object, the technical solution used in the present invention is, a kind of high-heat strength Filter Tuber For Clean Coal tackiness agent, and the tackiness agent added in Filter Tuber For Clean Coal making processes accounts for raw coal total amount 1 ~ 2%(weight ratio), described tackiness agent containing mass percent is:
