Emulsifier, tar coal water slurry fuel and preparation method thereof

The invention provides an emulsifier, a tar coal water slurry fuel and a preparation method of the tar coal water slurry fuel, and relates to the technical field of preparation of tar coal water slurry emulsifiers. The emulsifier provided by the invention comprises the following components in percentage by mass: 50-90% of polyaluminum chloride, 5-30% of sodium carbonate and 5-20% of sodium chloride. The emulsifier provided by the invention has the characteristics of good dispersity, emulsibility and stability, can effectively improve the uniformity of tar coal water slurry fuel slurry, and does not generate precipitates. And the emulsifier provided by the invention is low in cost. Results of the embodiment show that the tar coal water slurry fuel prepared by the invention is uniform in slurry, is not layered, and does not generate precipitates within 48 hours. 本发明提供了一种乳化剂和焦油水煤浆燃料及其制备方法，涉及焦油水煤浆乳化剂制备技术领域。本发明提供的乳化剂，包括以下质量百分含量的组分：50～90％聚合氯化铝、5～30％碳酸钠和5～20％氯化钠。本发明提供的乳化剂具有良好的分散性、乳化性和稳定性的特点，能够有效的提高焦油水煤浆燃料浆体的均匀性，无沉淀生
