Nickel titanium alloy gas-liquid filter mesh is widely used in screening, gas and liquid filtration, and media separation due to its excellent performance in acidic and alkaline environments. This multifunctional material can be used in various media, playing a role in filtration and separation. The following is an introduction to nickel titanium alloy gas-liquid filter screens from the aspects of material characteristics, working principles, structural features, application fields, and performance advantages:

Nickel titanium alloy gas-liquid filter screen

1、 Material characteristics

Shape memory effect: Nickel titanium alloy has a unique shape memory function, which can restore to a predetermined shape under certain temperature conditions. This allows the gas-liquid filter screen to recover to its original state even after being deformed by external forces, ensuring the stability of the filtration performance.

Superelasticity: It has good superelasticity and can withstand large deformations without permanent deformation. In the process of gas-liquid filtration, it can effectively buffer fluid pressure and extend service life.

Corrosion resistance: Nickel titanium alloy has excellent corrosion resistance to various chemicals and can resist the erosion of corrosive components such as acid and alkali in gas-liquid media, making it suitable for various harsh working environments.

Biocompatibility: In some special application scenarios that may come into contact with biological fluids, nickel titanium alloys have good biocompatibility and will not have adverse effects on biological tissues, ensuring the safety of the filtration process.

2、 Working principle

When a gas with mist rises through a nickel titanium alloy gas-liquid filter at a certain speed, due to the inertia of the mist rising, the mist collides with the filter filaments and adheres to the surface of the filaments. The diffusion of mist on the surface of the filament and the gravitational settling of the mist result in the formation of larger droplets that flow along the filament to the junction of the two filaments. The wettability of the filament, the surface tension of the liquid, and the capillary action of the filament cause the droplets to grow larger and larger. When the accumulated droplets exceed the combined force of the gas lift force and the liquid surface tension, the droplets separate and fall from the filament, achieving the effect of gas-liquid separation.

3、 Structural characteristics

There are various weaving methods available, including plain weave, diagonal weave, satin weave, etc., to meet different requirements for filtration accuracy and strength.

Uniform mesh size: The mesh size of the nickel titanium alloy gas-liquid filter is uniform and consistent, ensuring the uniformity and stability of filtration, and effectively intercepting droplets and impurities of different particle sizes.

Strong customizability: Different shapes, sizes, and specifications of filter screens can be customized according to actual application needs, such as circular, square, rectangular, as well as different parameters such as wire diameter and mesh size.

4、 Application Fields

Chemical industry: Used in distillation, absorption, evaporation and other processes in chemical production, it can effectively separate gas-liquid mixtures, improve product quality, reduce equipment corrosion, and lower production costs.

Petroleum industry: In the fields of petroleum refining and oil and gas extraction, it is used in equipment such as oil and gas separators and tower top condensation systems to achieve efficient separation of oil and gas and improve the recovery and utilization rate of oil and gas.

Pharmaceutical industry: In the pharmaceutical process, it is used to filter bubbles, impurities, etc. in the drug solution to ensure the quality and purity of the drug, while its biocompatibility also ensures that it will not contaminate the drug.

Food and beverage industry: used for gas-liquid separation in the production process of food and beverage, such as in the filling process of beer and beverages, which can remove bubbles in the liquid and improve the appearance and taste of the product.

In the field of environmental protection, it is used for gas-liquid separation and filtration in environmental protection equipment such as sewage treatment and exhaust gas treatment, reducing pollutant emissions and protecting the environment.

5、 Performance advantages

Efficient filtration: It can efficiently intercept and separate liquid droplets and impurities in gas-liquid mixtures, with high filtration accuracy, and can meet the strict filtration requirements of different industries.

Small pressure loss: Due to its unique structure and material properties, the pressure loss of gas passing through the filter is relatively small, which can reduce the operating energy consumption of the equipment.

Long service life: It has good corrosion resistance, wear resistance, and fatigue resistance, and can operate stably for a long time in harsh working environments, reducing replacement frequency and lowering maintenance costs.

Easy to install and maintain: lightweight, small in size, easy to install, and relatively simple to clean and maintain. It can be restored to its filtering performance through physical or chemical cleaning methods.
