Working principle and introduction
The static mixer is an independent type of chemical unit equipment. The mixing process is completed by mixing the components inside the tube, causing the fluid to rotate left and right, changing the flow direction movement, pushing from the center to the periphery, pushing the periphery to the center, and perfecting the radial circulation mixing. The purpose of mixing effects.
Xinrui static mixer, focusing on quality and absorbing advanced production technology at home and abroad, is a large domestic manufacturing company.
Seven series, thousands of specifications, used in liquid-liquid, gas-liquid, solid-liquid, gas-liquid-solid, gas-gas mixing, dispersion, emulsification, reaction, absorption, extraction, enhanced heat transfer, etc. More than ten industries are widely used.

SV static mixer product features
The SV internal unit is assembled from well-designed corrugated sheets. The product itself has no moving parts. The special structure and fluid motion of the unit make the mutually incompatible fluids disperse and mix with each other to achieve a good mixing effect. The SV type unit is a cylinder assembled from a corrugated board of a certain specification. Technical characteristics: the highest dispersion degree is 1-2 μm, and the liquid-liquid phase unevenness is a√x ≤ 1 to 5%. The pressure drop calculation of the product is based on the hydraulic diameter and takes into account the effects of void ratio and friction coefficient.

Distributor product characteristics
This product is designed for the application of static mixers, two Yin or more fluids are designed for the smooth delivery of fluids before entering the static mixer.
During the transportation process, the mixing ratio is often affected by the imbalance of the delivery pressure of each unit. In this case, the Venturi tubular distributor must be selected. The Venturi tube distributor has the performance of the injection booster pump. Under the condition of flow flow, the outlet pressure of the material is brought to the required pressure. The distributor is mainly composed of a nozzle, a receiving chamber, a mixing chamber, a diffuser, etc., the main flow passes through the nozzle to generate a pressure drop, the secondary flow is drawn into the receiving chamber of the venturi, and the mainstream and the secondary flow are mixed in the mixing chamber and then passed. The diffusion chamber, at this time, the discharge pressure to the diffusion chamber is greater than the secondary inlet pressure, which is smaller than the mainstream inlet pressure. In this way, the fluid can be smoothly delivered to the static mixer for mixing. However, due to the specificity of the process, the delivery pressure of each fluid is balanced. In this case, a form of dispenser can be selected according to the flow rate of each fluid and the specific process requirements.
Distributor form
Dispenser product use
It is suitable for two or more fluid feeds. When the mainstream and secondary flow pressures are unbalanced, the venturi tubular distributor is used. When the mainstream and secondary flow pressures are balanced, the general form distributor is used.
Distributor application example
In a chemical chemical plant, in the process of liquefied gas alkali washing, due to the imbalance of the mainstream secondary flow pressure, the Venturi tubular distributor was selected to solve the problem of mainstream and secondary flow feeding, so that it can be smoothly pumped. Further mixing with a SK type static mixer to meet the process requirements.
