Abstract: Provided is a concentration device for coal water slurry, belonging to the technical field of coal water slurry preparation equipment, including a grinding shell, where a grinding mechanism is connected in the grinding shell. A lower part of the grinding shell is connected to a filter unit, where the filter unit is correspondingly arranged with a discharge port of the grinding mechanism. A lower part of the filter unit is correspondingly provided with a pulverized coal particle size distribution mechanism. An outlet end of the pulverized coal particle size distribution mechanism is communicated with a stirrer. The grinding mechanism includes a first bracket, where the first bracket is fixedly connected to inner side walls of the grinding shell. The first bracket is connected with step-by-step grinding units, a first adjusting unit and two second adjusting units.

Abstract: A preparation method of a cube-like ZnSnO3 composite coated with highly graphitized fine ash comprises steps: S1: with the gasified fine slag of pulverized coal as a raw material, preparing the fine ash by adopting a three-step acidification method; and S2: adding the fine ash prepared in the Si into a container filled with distilled water, ultrasonically dispersing for 20-40 min, adding equal molar masses of SnCl4.5H2O and (Zn(NO3).6H2O respectively, uniformly stirring, dropwise adding ammonia into the mixed solution and magnetically stirring until the pH value of the mixed solution is 12, heating the mixed solution, washing the product obtained with deionized water and ethanol for 2-4 times, and finally drying to obtain a ZnSnO3@fine composite. With the dielectric property and conductivity adjusted, the composite prepared reveals a good impedance matching performance and an improved MA performance.
