Abstract
The invention discloses preparation and application methods of high-strength and environment-friendly coal briquette adhesive. The adhesive is prepared by organic adhesive, clay, sodium humate, cellulose, resin and the like. The preparation method includes: mixing, by weight percentage, 10-25% of organic adhesive and 50-75% of clay in a reactor, sufficiently stirring for 3-15 minutes, slowly adding, by weight percentage, 10-20% of sodium humate and 1-8% of resin into the mixture, and adding, by weight percentage, 8-20% of cellulose into the reactor during stirring to obtain the coal briquette adhesive. The coal briquette is added into pulverized coal to allow the pulverized coal to have specific shapes. The coal briquette adhesive prepared by the preparation method has the advantages that the raw materials, except the clay, of the adhesive are organic matter, the combustion products of the coal briquette adhesive are carbon dioxide and water, and the coal briquette adhesive does not cause environment pollution and does not excessively lower the heat productivity of coal briquette; the organic matter is high in viscosity, high fall strength can be achieved by adding a small amount of organic matter, and high cold and thermal intensity and good thermal stability are achieved.

Technical field
The present invention relates to a kind of high-strength environment-friendly coal briquette bond, particularly a kind of system of high-strength environment-friendly coal briquette bond
The standby and its using method in coal dust.
Background technology
Coal in a short time will be always in occupation of leading position as the main energy resources of China, but its combustion product institute
The environmental problems such as the greenhouse effect that causes, haze gradually cause the attention of people, in the call of global call " energy-conservation, reduction of discharging "
Under, if Chinese Government holds to the people of the world：Discharge in the year two thousand thirty carbon dioxide is reached peak value and will strive to reach peak early, be
This, Chinese Government has formulated corresponding preferential policy guiding and has greatly developed clean coal technology.So-called clean coal technology is exactly coal
Gasification, liquefaction, the efficient burning of coal or anchracite duff made the technology such as moulded coal, wherein moulded coal is exactly to add in anchracite duff
Plus appropriate binding agent repressed, the coal with given shape that is prepared from of operation such as dry.
Coal briquette bond is to prepare a requisite class additive during moulded coal, and it mainly has organic bond, no
Machine binding agent and composite adhesive, the moulded coal made using organic bond is not only relatively costly, and water proofing property and heat are steady
Qualitative poor, and adopt moulded coal cold strength prepared by inorganic bond relatively low, also can increase ashes simultaneously, reduce caloric value, because
This, be primarily present in the market is compound binding agent, and it is by chemical industry macromolecule, inorganic material and a small amount of additional
Auxiliary agent is formed, and wherein chemical product can produce substantial amounts of harmful gass and dust through after burning, can be to environment and human body
Cause certain injury.Therefore, seek a kind of alternative, coal briquette bond of environmental protection and seem of crucial importance.
Content of the invention
