1. Product Overview

The High Efficiency Side Entry Mixer for Flue Gas Desulfurization (FGD) is a heavy-duty industrial agitation system specifically designed for large-scale absorption tanks used in power plants and environmental protection facilities.

It plays a critical role in limestone slurry preparation, absorption tower mixing, and continuous desulfurization reaction enhancement, ensuring stable SO₂ removal efficiency and improved environmental compliance.

This side entry mixer is widely applied in coal-fired power plants, chemical plants, steel mills, and industrial flue gas treatment systems where high-efficiency mixing and anti-sedimentation performance are required.

2. Working Principle

The mixer is installed on the side wall of large FGD absorption tanks. It generates strong horizontal flow circulation inside the tank, preventing solid deposition and ensuring uniform slurry concentration.

Key mixing actions include:

• Axial circulation flow for uniform slurry distribution

• Radial turbulence for enhanced chemical reaction

• Continuous suspension of limestone particles

• Prevention of sediment buildup at tank bottom

This ensures stable absorption efficiency and reduces scaling and blockages in FGD systems.
