Abstract

The invention relates to a coal-water slurry slurrying system and a method for a coal chemical industry. The system comprises a raw material bin (1), a vibrator feeder (2), a belt conveyor I (3), a magnetic separator (4), a bucket elevator I (5), a crusher (6), a bucket elevator II (7), a belt conveyor II (8), an intermediate bin (9), a screw conveyor (10), a belt weigher (11), a coal-water slurry screw feeder (12), a dispersing agent thinning tank (13), a water tank (14), a special coal-water slurry mill (15), a vibration sieve (16), a coal-water slurry buffer tank (17), a stabilizing agent thinning tank (18), a coal-water slurry filter (19), a bucket (20) for adjusting and treating stability, a homogeneous maturation tank (21), a slurry-storage tank (22), a slurry station (23) and a waste reservoir (24). The coal-water slurry slurrying system and the method for coal chemical industry in the invention have wide adaptability of coal varieties, small occupied area, long service life and high slurry-producing stability.

Description

(1) Technical field [0001] The invention relates to a coal chemical slurry making system and method, belonging to the technical field of coal chemical industry. (2) Background technology [0002] At present, coal-water slurry is widely used in the field of coal chemical industry, but there are many deficiencies in the pulping system and its process methods. In the conventional pulping system, the two-stage crushing method is often used, which not only has a complex structure, but also occupies a large area; at the same time, because it is extremely easy to mix metal impurities in the raw coal, it is easy to cause damage to the mill, reduce its service life, and affect The stability of pulp. (3) Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages, and provide a system and method for making water-based coal slurry for coal chemical industry with wide adaptability of coal types, small floor space, long service life an...
