In the field of industrial fluid processing, as a key equipment to ensure the stable operation of the system, the optimization of pressure loss in duplex filters is of crucial importance. This article will conduct an in-depth exploration into the flow velocity performance of C95800 bronze filter screens and S32760 stainless steel filter screens in duplex filters, aiming to provide a solid basis for the selection and optimization of filters.
I. Characteristics of Filter Screen Materials
The C95800 bronze filter screen is made of nickel-aluminum bronze and has excellent corrosion resistance. It performs outstandingly especially in corrosive medium environments containing hydrogen sulfide and can effectively resist chloride stress corrosion cracking. Its organizational structure is compact, with relatively high strength and hardness, capable of withstanding greater filtration pressure. Moreover, its surface is smooth, which helps to reduce fluid resistance.
The S32760 stainless steel filter screen belongs to super austenitic stainless steel, containing high contents of elements such as chromium and nickel, and has outstanding corrosion resistance, showing good tolerance to various acid and alkali solutions. It also has excellent creep resistance, can maintain a stable working state in high-temperature environments, has high strength, can adapt to complex and harsh working conditions, and at the same time has good processability, facilitating the manufacturing of filter screens in various shapes.
II. Comparative Analysis of Flow Velocity
(1) Flow Velocity Performance under the Same Working Conditions
Under the same conditions such as filtration area, filtration precision, and working pressure, the flow velocity of the C95800 bronze filter screen is relatively low. This is because the density of the bronze material is relatively large, resulting in slightly greater resistance to the fluid. Moreover, its pore structure is relatively complex, and the fluid will be hindered to some extent when passing through it, causing the flow velocity to slow down.
The flow velocity of the S32760 stainless steel filter screen is relatively high. The density of the stainless steel material is relatively small, and after precision processing, the surface of the filter screen is smooth and the pores are uniform and regular, which is conducive to the smooth passage of the fluid, thus achieving a higher flow velocity under the same conditions.
(2) Flow Velocity Stability under Different Flow Rates
When the flow rate gradually increases, the flow velocity stability of the C95800 bronze filter screen is relatively good. Thanks to its relatively high strength and hardness, the filter screen has less deformation under the impact of large flow rates, the pore structure remains stable, and it can maintain a relatively uniform flow velocity distribution. The increase in pressure loss is relatively gentle.
The S32760 stainless steel filter screen has relatively stable flow velocity at a small flow rate. As the flow rate increases, due to its relatively soft material, under the impact of a relatively large flow rate, the filter screen may experience slight deformation, resulting in local enlargement or reduction of pores, and the uniformity of the flow velocity distribution will be affected to some extent. The pressure loss will also increase accordingly, but it is still within an acceptable range overall.
III. Comparison of Pressure Loss
(1) Static Pressure Loss
The static pressure loss of the C95800 bronze filter screen is relatively large. On the one hand, it is because the resistance coefficient of the bronze material is relatively high. On the other hand, its complex pore structure also increases the path and resistance of fluid flow, so that there is a certain pressure difference on both sides of the filter screen when there is no fluid passing through.
The static pressure loss of the S32760 stainless steel filter screen is relatively small. The resistance coefficient of the stainless steel material is low, and the structure design of the filter screen is reasonable with unobstructed pores, so the pressure difference on both sides of the filter screen in the non-flowing state of the fluid is relatively small.
(2) Dynamic Pressure Loss
During the dynamic operation process, the growth rate of the pressure loss of the C95800 bronze filter screen is relatively slow. Although the initial pressure loss is relatively large, due to its good flow velocity stability and strong anti-deformation ability, as the flow rate increases, the increase amplitude of the pressure loss is relatively small, and it can maintain a relatively stable pressure state for a long time.
The growth rate of the dynamic pressure loss of the S32760 stainless steel filter screen is relatively fast. The initial pressure loss is small, but with the increase of the flow rate and the deformation of the filter screen, the pressure loss rises rapidly. Especially under high-flow working conditions, the pressure loss may exceed the system design requirements, which will have a certain impact on the operating efficiency of the filter.
IV. Optimization Suggestions
(1) Optimization of Filter Screen Selection
Reasonably select the filter screen material according to different working conditions. In scenarios where highly corrosive media are being processed and the requirement for flow velocity is not high, the C95800 bronze filter screen is a relatively ideal choice. While in environments where the requirement for flow velocity is relatively high and the corrosiveness of the media is relatively weak, the S32760 stainless steel filter screen has more advantages.
(2) Optimization of Structural Design
For the C95800 bronze filter screen, the pore structure of the filter screen can be optimized, such as adopting pores with special shapes like trapezoidal holes and rhombic holes, to improve the fluid flow path and reduce resistance. At the same time, the supporting structure of the filter screen can be increased to improve its anti-deformation ability and reduce deformation under large flow rates, thereby optimizing the performance of flow velocity and pressure loss.
For the S32760 stainless steel filter screen, advanced processing technologies can be adopted to improve the surface smoothness of the filter screen and reduce the frictional resistance when the fluid passes through. The thickness and mesh number of the filter screen can be reasonably designed. On the premise of ensuring the filtration precision, the resistance of the filter screen to the fluid can be reduced. In addition, the filter screen can also be reinforced to prevent deformation under high flow rates and maintain the uniformity of the flow velocity and the stability of the pressure loss.
(3) Optimization of Operating Parameters
During the actual operation process, the flow rate and pressure of the fluid should be reasonably adjusted according to the working state of the filter. Avoid operating under high flow rates and high pressures for a long time, reduce the load on the filter screen, and extend the service life of the filter screen. Meanwhile, the filter should be regularly cleaned and maintained to keep the cleanliness of the filter screen, prevent impurities from clogging the pores of the filter screen, which may lead to a decrease in flow velocity and an increase in pressure loss.
In conclusion, the C95800 bronze filter screen and the S32760 stainless steel filter screen each have their own advantages and disadvantages in duplex filters. In practical applications, factors such as working conditions and filtration requirements should be comprehensively considered, the filter screen material should be reasonably selected, and the pressure loss should be effectively reduced and the operating efficiency and economic benefits of the filter should be improved by optimizing the filter screen structure and operating parameters.
