TCN type vertical slurry pump
TCN type vertical slurry pump is used for conveying phosphoric acid slurry medium. It is one of the key pumps of the device. It can be installed on the top of the extraction tank.The main products to provide a reasonable slurry.
Conveying medium: phosphate slurry of dihydrate
Solid content: phosphogypsum (mainly composed of CaSO4·2H2O and undecomposed phosphate and acid insoluble substances).25% ~ 32%
Liquid phase: phosphoric acid (P2O5) 20%~30%;Free sulphuric acid H2SO41%~4%;Fluorosilicate H2SiF61%~3%.Chlorine root CL¯A small amount of
Viscosity: 5 ~ 15 mpa, s
Density :(slurry) 1.3-1.5t /m³
Medium temperature: 70 ~ 85 ℃
The main difference between the working conditions of the device and the dihydrate phosphoric acid device is that the concentration of liquid phase phosphoric acid and the reaction temperature are both high. The specific data are as follows:
Liquid phosphate P2O540%~48%;Reaction temperature 95 ~ 105 ℃.All the above media are under the condition of intense stirring.
