Examples
Embodiment 1
[0018] Weigh 20 parts of deionized water and 0.1 part of dispersant and pour them into the container, stir well and mix well, then add 3 parts of BDO waste water and stir to dissolve, add coal powder quickly while stirring at 200r / min, and then add it at 1200r / min After stirring for 5 minutes at a certain speed, the coal-water slurry was obtained.
[0019] Among them: the slurry concentration of coal powder is 61%, and the dispersant is a naphthalene-based coal water slurry dispersant.
Embodiment 2
[0021] Weigh 35 parts of deionized water and 0.2 parts of dispersant and pour them into the container, stir and mix well, then add 5 parts of BDO waste water and stir to dissolve, and quickly add coal powder while stirring at 350r / min, and then at 1500r / min After stirring for 7 minutes at a certain speed, the coal-water slurry was prepared.
[0022] Among them: the slurry concentration of coal powder is 61%, and the dispersant is a naphthalene-based coal water slurry dispersant.
Embodiment 3
[0024] Weigh 50 parts of tap water and 0.3 parts of dispersant and pour them into the container, stir well and mix evenly, add 7 parts of BDO wastewater and stir to dissolve, and quickly add coal powder while stirring at 500r / min, and then at a speed of 1800r / min After stirring for 10 minutes, the coal water slurry was obtained.
[0025] Among them: the slurry concentration of coal powder is 61%, and the dispersant is a naphthalene-based coal water slurry dispersant.
