Embodiment 1
[0032] Below with 4 8 ton tanks (hydrolyzers) illustrate the use situation of the hydrolyzer equipment that provides the direct power that drives stirring device with hydraulic device of the present invention.
[0033] Firstly, the granulated polyacrylamide polymer is sent into the hydrolyzer through the conveying device. Raise the temperature to meet the process requirements. When the temperature is reached, according to the process requirements, add the required amount of solid sodium hydroxide into the hydrolyzer. At this time, the colloidal particles enter the state of hydrolysis, and the hydrolysis is carried out according to the time required by the process. After the hydrolysis is completed, the material is unloaded and sent to the next process link by the conveyor. Please refer to Table 1 for relevant process conditions and hydrolysis conditions.

Embodiment 2
[0037] Below with 4 5 ton tanks (hydrolyzers), illustrate the use of the hydrolyzer equipment that provides the direct power of driving stirring device with hydraulic device of the present invention.
[0038]Firstly, the granulated polyacrylamide polymer is sent into the hydrolyzer through the conveying device. Raise the temperature to meet the process requirements. When the temperature is reached, according to the process requirements, add the required amount of solid alkali into the hydrolyzer. At this time, the colloidal particles enter the state of hydrolysis, and the hydrolysis is carried out according to the time required by the process. After the hydrolysis is completed, the material is unloaded and sent to the next process link by the conveyor. Please refer to Table 2 for relevant process conditions and hydrolysis conditions.
