Polymer Preparation Unit for Automatic Polymer Dosing System

• The polymer dosing system is designed to provide highly accurate dosing. It utilizes advanced metering pumps such as peristaltic pumps, diaphragm pumps, or piston pumps. These pumps, combined with precise flow - control valves and sensors, can achieve a very high level of dosing accuracy. For instance, in industrial water treatment processes, the system can dose polymers with an accuracy of up to ±0.5% of the set value. This accuracy is crucial in applications where the correct amount of polymer is essential for the desired process outcome, such as in the production of high - quality paper or efficient wastewater treatment.
• The real - time adjustment capabilities of the system further enhance its accuracy. Sensors continuously monitor process parameters like flow rate, temperature, and the characteristics of the substances being treated. Based on this data, the control system can make immediate and precise adjustments to the polymer dosing rate. In a mining operation, if the slurry composition changes, the system can quickly adapt and adjust the polymer dosing to maintain optimal flocculation and solid - liquid separation.

1. Polymer Preparation
   • The system first prepares the polymer solution. Polymers usually come in powder or liquid concentrate form. If it's in powder form, it's mixed with a suitable solvent (often water) in a mixing tank. The mixing process is carefully controlled to ensure complete dissolution of the polymer without clumping or incomplete mixing.
   • For example, in a water treatment plant, a polymer powder might be slowly added to a tank of water while the mixer is running at an appropriate speed to create a homogeneous polymer solution.
2. Dosing Mechanism
   • The prepared polymer solution is then dosed into the target process. There are different dosing mechanisms, such as peristaltic pumps, diaphragm pumps, or piston pumps. These pumps are calibrated to dispense a precise volume of the polymer solution. The dosing rate can be adjusted based on factors like flow rate of the process stream, the concentration of solids in the stream, and the desired treatment effect.
   • In a papermaking process, the polymer dosing system uses a diaphragm pump to add the polymer solution to the pulp slurry. The pump's dosing rate is adjusted according to the pulp's consistency and the quality requirements of the final paper product.
3. Control and Monitoring
   • Modern polymer dosing systems are equipped with advanced control and monitoring features. Sensors are used to measure parameters such as the polymer solution's concentration, the flow rate of the dosing pump, and the overall process conditions. The control system then adjusts the dosing rate in real - time based on these measurements to maintain optimal performance.
   • For example, in a mining operation, sensors monitor the slurry's turbidity and the polymer solution's flow rate. If the turbidity increases, the control system can increase the dosing rate of the polymer to improve the settling of solid particles.
