Problems solved by technology
[0003] Due to the high water content in coal-water slurry, more than 30% of the transportation cost is used to transport water, resulting in great waste, and the equipment for producing coal-water slurry in the prior art is generally large in scale and high in transportation costs, so it is not suitable The needs of SMEs or remote areas
In addition, due to the low temperature in the northern region, the coal-water slurry is easy to freeze and difficult to store, which is not conducive to the popularization and use of coal-water slurry

The invention discloses pulverized coal pulping equipment and a pulping method thereof. The pulverized coal pulping equipment comprises a ladle pouring machine, a screw feeder, a strong stirrer, a water box, a ball mill special for water coal pulp, a buffer tank, a pulp filtering device and a pulp storage tank which are connected in sequence. A ladle pouring dust removing device is arranged in the ladle pouring machine, and sealing devices are arranged on the connecting portion of the ladle pouring machine and the screw feeder and the connecting portion of the screw feeder and the strong stirrer. According to the pulverized coal pulping equipment and the pulping method thereof, pulverized coal is used for manufacturing water coal pulp, during transportation, only the pulverized coal needs to be transported, and the transportation cost is lowered. In the pulverized coal pulping equipment, the specifications of all machines can be flexibly designed, mounting and using are easy and convenient, and the pulverized coal pulping equipment is particularly suitable for popularization and application in middle and small-sized enterprises or remote areas.
Description
technical field [0001] The invention relates to the technical field of coal water slurry production, in particular to a pulverized coal slurry production equipment and a slurry production method thereof. Background technique [0002] Coal water slurry is a mixture of coal, water and chemical additives according to certain requirements. It is a liquid fuel that emerged in the 1970s. Compared with direct combustion of coal, it has stable combustion, less pollution emissions, fluidity and stability. It is better and can be atomized and burned. It is a relatively cheap clean fuel with high combustion efficiency and low pollution. It can replace heavy oil to alleviate the energy security problem of oil shortage. The manufacturing technology of coal water slurry has also been greatly developed. [0003] Due to the high water content in coal-water slurry, more than 30% of the transportation cost is used to transport water, resulting in great waste, and the equipment for producing ...
