In August 2025, Greatwall Mixer dispatched its after-sales engineer to Guangxi to provide on-site installation supervision and commissioning services for a hydrogen peroxide project undertaken by a local chemical enterprise. The core task involved the precise installation and tuning of agitators for the first and second stage acid washing tanks—key components in the production process. The equipment has now passed operational validation and has been officially put into use, operating smoothly with all technical indicators meeting expectations.

About Hydrogen Peroxide

Hydrogen peroxide (H₂O₂) is a clean and highly efficient green oxidant. As it decomposes into only water and oxygen, it offers excellent environmental compatibility. It is widely used in industries such as textile dyeing, paper bleaching, electronics cleaning, water treatment, food processing, pharmaceutical intermediate synthesis, and rubber additive manufacturing. With the rapid development of clean energy, green manufacturing, and fine chemicals, the hydrogen peroxide industry demands higher capacity, product purity, and greater safety and automation in its production processes.

Technical Challenge: Process Bottlenecks in Large-Scale Washing Tank Agitator Systems

In the anthraquinone-based hydrogen peroxide process, acid washing tanks serve as critical units for regenerating and purifying the working solution by removing impurities. However, they pose significant challenges for agitator system design. Acidic media are highly corrosive and moderately viscous; combined with large tank volumes and deep liquid levels, conventional agitators often struggle to generate effective axial flow and bottom agitation. This leads to flow dead zones and phase separation, reducing impurity removal efficiency. Additionally, strong foaming and organic phase volatilization can disturb interface stability and even introduce safety risks if not properly controlled. Achieving optimal shear force while maintaining energy efficiency further increases the demands on the agitator’s mechanical performance and adaptability.

Tailored Solution: Multi-Stage Agitator Configuration for Optimized Flow and Process Stability

To overcome these complex technical hurdles, Greatwall Mixer delivered a customized agitator solution tailored to real working conditions, supported by extensive industry experience and CFD (Computational Fluid Dynamics) simulation. The system features a multi-stage agitator configuration engineered for zoned flow control and collaborative performance:

A large-diameter anti-foam impeller at the top provides gentle agitation to suppress foam formation and reduce gas-liquid entrainment, ensuring surface stability;

Mid-level three-blade detachable marine propellers generate strong axial flow, enabling full-tank circulation and consistent mixing across varying depths; A dual-disc inclined-blade turbine agitator at the bottom offers high shear and deep circulation to enhance phase dispersion, accelerate mass transfer, and eliminate sedimentation.

This integrated solution ensures high-efficiency mixing, improved separation quality, and stable long-term operation. It also incorporates corrosion-resistant materials, optimized shaft sealing, and power matching for reliable performance under high-load, extended-cycle conditions.

The successful delivery of the Guangxi project showcases Greatwall Mixer’s deep technical strength in corrosive, complex chemical process environments and reinforces its position as a trusted solution provider in the hydrogen peroxide industry. Moving forward, Greatwall Mixer will continue to focus on technology-driven innovation, offering intelligent, energy-efficient, and reliable mixing systems to support the sustainable development of the clean chemical and advanced manufacturing sectors.
