Product Introduction:
Static mixer is a kind of high efficiency mixing equipment without moving parts, its basic working mechanism is to use the mixing unit fixed in the tube to change the flow state of the fluid in the tube, in order to achieve the purpose of good dispersion and full mixing between different fluids. The device is widely used and non-removable.
How it works:
Let the fluid flow in the pipeline impact various types of plate components, increase the velocity gradient of the fluid laminar flow movement or form turbulence, laminar flow is "segmentation - position movement - reconvergence", turbulent flow, in addition to the above three situations, the fluid will also produce violent eddy currents in the direction of the section, there is a strong shear force for the fluid, so that the fluid further segmentation and mixing. The final mixture forms the desired emulsion. The reason why it is called a "static" mixer means that there are no moving parts in the pipeline, only static components.
The mixing process of static mixers is carried out by a series of mixing units of different specifications installed in hollow pipes. Due to the role of the mixing unit, the fluid sometimes turns left, sometimes turns right, and constantly changes the direction of the flow mixer, which not only pushes the central fluid to the periphery, but also pushes the peripheral fluid to the center, resulting in a good radial mixing effect. At the same time, the rotation of the fluid itself will also occur on the interface where the adjacent components are connected, and this perfect radial circulation mixing effect makes the material obtain the purpose of mixing evenly. Static mixer is a kind of efficient mixing equipment without movement, through the internal parts of the mixing unit fixed in the tube, so that two or more strands of fluid produce cutting, shearing, rotation and remixing, to achieve the purpose of good dispersion and full mixing between the fluids.

The SX-type static mixer is a highly efficient pipeline mixing device without moving parts, which is widely used in the liquid-liquid, gas-liquid mixing and heat and mass transfer processes in industries such as chemical engineering, environmental protection, and pharmaceuticals. In the sulfuric acid dilution device, the SX-type static mixer is often used as the core mixing unit to replace the traditional mechanical agitator, so as to achieve a safe and uniform mixing effect. The following is a detailed introduction to the SX-type static mixer:
I. Structure and Working Principle
Basic Structure
It is composed of a series of spiral units (mixing elements) fixed inside the pipeline, which are usually made of corrosion-resistant materials (such as 316L stainless steel, Hastelloy, PTFE lining, etc.).
The units are arranged alternately at a specific angle, forming a continuous dividing, shearing and rotating flow path.
Mixing Principle
Laminar Flow Cutting: When the fluid passes through the spiral units, it is repeatedly divided and recombined to achieve microscopic mixing.
Turbulent Diffusion: At higher flow rates, the fluid forms turbulence, enhancing the mass transfer efficiency.
Self-cleaning Function: The design without dead corners avoids the residue or blockage of materials.
II. Core Advantages in Sulfuric Acid Dilution
High Safety
There are no mechanical moving parts, eliminating the risk of leakage or sparks caused by agitator failures (especially suitable for strongly corrosive, flammable and explosive environments).
It can cooperate with the jacket cooling, and directly dissipate heat through the outer wall of the mixer, reducing the temperature rise during the dilution process.
Excellent Mixing Efficiency
A single SX mixer can achieve a mixing uniformity of more than 90% (depending on the number of units and the flow rate).
It is suitable for large-flow continuous dilution (such as industrial-grade sulfuric acid dilution production lines).
Low Maintenance Cost
With a simple structure, it does not require vulnerable parts such as motors and bearings, and has high long-term operation stability.
The design of corrosion-resistant materials can make the service life reach more than 10 years (it is necessary to regularly check the wear of the inner wall).
III. Key Design Parameters
Number of Mixing Units
Generally, 3-6 units are required (adjusted according to the mixing accuracy requirements. The more units, the more uniform the mixing).
For sulfuric acid dilution, 4-5 units are recommended, taking into account both efficiency and pressure drop.
Flow Rate and Pressure Drop
Optimal flow rate range: 0.3-1.5 m/s (too low will lead to insufficient mixing, and too high will significantly increase the pressure drop).
