Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical engineering, and particularly relates to a rapid PAM solution feeding system. Background Art
[0002] As one of the most important agents in the separation and sedimentation process, the full and efficient preparation of PAM (polyacrylamide) is particularly important. When polyacrylamide is dissolved, it needs to be added while stirring. The water quality, temperature of the dissolving water, and stirring speed will all affect its dissolution rate. When polyacrylamide is dissolved, hydrogen bonds are formed between molecules. As the stirring speed increases, the hydrogen bonds become longer and stronger, forming a molecular chain with a network structure. This structure causes the solution viscosity to gradually increase. The existing PAM solution feeding device only has a simple paddle stirring. The dissolution efficiency of PAM is low. PAM forms a colloid due to slow dissolution at low temperature, clogging pipelines and filters. Moreover, the colloid has a relatively high viscosity and certain fluidity, making it very difficult to clean.
[0003] Based on the above situation, the utility model proposes a rapid PAM solution feeding system, which can effectively solve the above problems. Summary of the Utility Model
