Dry pulverized coal=30:100, additive:Dry pulverized coal=0.8:100.Additive selects naphthalenesulfonate formaldehyde condensation compound.The water coal being made
The solid masses concentration of slurry is 60%.
The apparent viscosity of slurry utilizes rotary viscosity design determining.
(2) implementation result
Table 2 gives dense into slurry viscosity and most great achievement slurry through sludge sludge water-coal-slurry modified under different ultrasonic powers
Degree.As seen from Table 2, compared with undressed raw sewage, the sludge water-coal-slurry being made by ultrasonically-modified sludge has
Have relatively low into slurry viscosity and higher slurry concentration, show the paste-forming properties enhancing of ultrasonically-modified sludge.Ultrasonic power is got over
Greatly, lower into slurry viscosity, maximum slurry concentration is higher.Because ultrasonic power is big, cavitation is just stronger, to sludge
Disintegration effect just becomes apparent from.In addition, cavitation supervenes fuel factor, and during ultrasonication, sludge local temperature
Rise.During ultrasonic power increase, reach that the time that identical ultrasonic intensity needs is short, radiating is few, sludge local temperature water
It is flat higher, therefore sludge disintegration effect can be higher.
Table 2. is through sludge sludge water-coal-slurry modified under different ultrasonic powers into slurry viscosity and maximum slurry concentration
