| titleOfInvention | A kind of preparation method and application method of the retardant for preventing drying brown coal spontaneous combustion |
| abstract | A kind of preparation method and application method of the retardant for preventing drying brown coal spontaneous combustion, belong to the preparation method and application method for preventing coal spontaneous combustion retardant.The retardant component (A) accounts for the main retardants of 60 80wt%, and component (B) accounts for 20 40% secondary catalyst.Preparation method：(1) sample preparation；(2) secondary retardant is prepared at a certain temperature；(3) it is uniformly mixed into retardant powder；(4) ratio of retardant powder and water by weight 1: 18 is taken to be sufficiently mixed into retardant solution；(5) based on mass volume ratio, by 1：The resistance solution of 0.1 2.0 ratios is uniformly sprayed on coal sample surface.The more former drying brown coal of activation energy for spraying the resistanceization coal sample after resistanceization solution in the moisture evaporation stage improves more than 25%, more than 170% is improved in the more former drying brown coal of the activation energy of oxygen uptake oxidation stage, lignite spontaneous combustion critical-temperature can bring up to more than 136 DEG C by 75 DEG C or so of raw coal, resistanceization significant effect.The retardant economy, pollution-free, convenient transportation, using simple, it is easy to operation. |
