Problems solved by technology
[0003] However, in the prior art, the proportion modulation and transportation of coal-water slurry are usually separated. On the one hand, because the coal-water slurry needs to be stored independently after it is made, and there is contact with the outside world during the process of pipeline transportation, It will affect the ratio stability of coal water slurry, and on the other hand, it will also reduce the delivery efficiency of coal water slurry

Description
【Technical field】 [0001] The invention relates to the technical field of coal-water slurry processing and conveying devices, in particular to an integrated device for ratio modulation and conveying of coal-water slurry. 【Background technique】 [0002] Coal water slurry is a low-pollution, high-efficiency, pipeline-transportable kerosene-based fluid fuel that is obtained through physical processing of about 65% of coal, 34% of water and 1% of additives. It not only maintains the original physical characteristics of coal, but also has the same fluidity and stability as oil, and can be easily stored, pipelined and atomized for combustion like oil. Coal water slurry has changed the traditional combustion method of coal. Its combustion efficiency can reach more than 95%, and the emission of sulfur dioxide, nitrogen oxides and soot concentration can meet the environmental protection requirements. Therefore, it is widely used and has huge advantages in environmental protection and ...
