Overview
The high-flow filter cartridge filter is a filtration equipment specifically designed to handle high-flow liquid or gas media. It is widely used in numerous industrial fields and some civil scenarios with high requirements for flow. With its high-efficiency filtration ability, large flux, and reliable performance, it can meet the needs of large-scale production or high-flow processing while ensuring the effective filtration of media, and plays an important role in industries such as chemical engineering, pharmaceuticals, electronics, food and beverages, and water treatment.
Working Principle
I. Feeding Process:
The high-flow liquid or gas media that need to be filtered are transported to the inlet end of the high-flow filter cartridge filter through large-diameter pipelines that match them. Relying on external forces such as pumping pressure, the media continuously pour into the filtering chamber inside the filter. During this process, in order to ensure the uniformity and effectiveness of subsequent filtration, special flow-guiding structures are often set inside the filter, allowing the media to be distributed relatively evenly in the chamber and avoiding situations such as excessive or too slow local flow velocities.
II. Filtration Stage:
The core filtering component is the high-flow filter cartridge. Such cartridges are usually made of high-performance filtering materials, such as polyethersulfone, polypropylene, etc., and are produced through special processes, having a large filtering area and an appropriate pore size distribution. When the high-flow media flow through the filter cartridges, impurity particles will be intercepted by the pore structure of the cartridges, attached to the surface of the cartridges or inside the pores, while the clean liquid or gas can smoothly penetrate the cartridges and be discharged from the outlet of the filter, thereby realizing the separation of impurities in the media from the pure media and achieving the purpose of filtration and purification.
III. Residue Discharge and Maintenance:
As the filtration continues, the impurities retained on the filter cartridges will continue to increase, resulting in a gradual increase in the filtration resistance and a corresponding decrease in the filtration efficiency. When specific set conditions are met (such as when the filtration resistance reaches the preset value or the filtration flow rate drops to a certain extent), it is necessary to clean or replace the filter cartridges. During the operation, first close the feed valve to stop the input of the media, then open the residue discharge port (if equipped) to discharge the residual media and some loose impurities inside the filter, and then carefully take out the filter cartridges. If the filter cartridges are reusable, they can be cleaned, disinfected (if necessary), dried, etc. according to the specified cleaning procedures and then reinstalled for use; if they are not reusable, replace them with new ones. After the maintenance is completed, the filter can be restarted to restore its normal filtration working state.
Performance Characteristics
I. High-Flow Processing Capacity:
The high-flow filter cartridge filter is originally designed to deal with high-flow media. It has a large flux and can handle a large amount of liquid or gas media per unit time, meeting the strict flow requirements of large-scale material transportation and supporting large equipment in industrial production, effectively improving production efficiency and ensuring the smooth progress of the entire process flow.
II. High-Efficiency Filtration Performance:
It has a good interception effect on impurity particles of different particle sizes. Even for impurities with small particle sizes, under the reasonable selection of filter cartridge materials and pore sizes, a high filtration efficiency can be achieved. Usually, for impurities with a particle size in the range of several micrometers to dozens of micrometers, the filtration efficiency can reach more than 90%. It can effectively remove suspended substances, colloids, microorganisms, and dust, particulate matter, etc. in the media, ensuring that the purity of the filtered media meets the corresponding process standards or usage requirements.
III. Diversity and Compatibility of Filter Cartridges:
There are a variety of filter cartridges available, which can be selected for installation and use according to different characteristics of the filtering media (such as acidity and alkalinity, chemical compatibility, temperature, etc.), filtration accuracy requirements, and flow size. Moreover, the replacement operation of the filter cartridges is relatively simple, facilitating flexible adjustment of the filtration scheme according to specific situations in practical applications to adapt to different working condition changes.
IV. Compact and Reasonable Structure:
The overall structural design is compact. While ensuring high-flow processing capacity and high-efficiency filtration functions, it tries to minimize the floor area occupied by the equipment, which is convenient for installation and layout in various limited space environments. It is especially suitable for some places with tight space but the need for high-flow filtration, such as specific workstations in some industrial plants or small water treatment stations.
V. Simple Operation and Easy Maintenance:
The operation interface of the equipment is simple and intuitive. Operators can master the basic start-up, stop, flow adjustment, and routine maintenance operation processes after simple training. The daily maintenance work mainly focuses on the replacement and cleaning of the filter cartridges, without the need for complicated tools and professional maintenance skills, which can effectively reduce the maintenance cost and management difficulty of the equipment and ensure the long-term stable operation of the equipment.
Structural Components
I. Shell:
The shell is generally made of high-strength engineering plastics, stainless steel, etc., and is formed through welding, assembly and other processes. It has good sealing performance, which can effectively prevent the leakage of media during the filtration process, and also has sufficient strength to withstand the pressure generated by the internal high-flow media and possible external impact forces. Its shape is commonly cylindrical, square or other shapes that are convenient for pipeline connection and space layout. Its appearance is usually processed to make it more beautiful and easy to clean and maintain.
II. High-Flow Filter Cartridge:
As the core filtering element, the quality and performance of the high-flow filter cartridge directly determine the filtration effect of the filter. It is made of specific filtering materials through folding, winding and other processes to increase the filtering area and improve the filtration efficiency. The two ends of the filter cartridge are usually equipped with sealing structures to ensure good sealing at the connection parts with the inside of the filter after installation, preventing the media from bypassing and ensuring the accuracy and stability of the filtration.
III. Inlet, Outlet and Residue Discharge Port (if available):
The inlet is responsible for introducing the high-flow media to be filtered into the filter. The diameter size of the inlet is designed according to the actual flow demand and is connected to the external delivery pipeline by a suitable connection method (such as flange connection, quick coupling connection, etc.) to ensure that the media can enter the filter smoothly and efficiently. The outlet is used to discharge the clean media after filtration. The same needs to consider the flow matching and the convenience of connection with the subsequent pipeline. Some high-flow filter cartridge filters are also equipped with a residue discharge port, which is convenient for discharging the internal residual impurities and media during maintenance. The residue discharge port is generally equipped with a corresponding valve for control, which is simple to operate and convenient to use.
IV. Internal Flow-Guiding and Support Structure:
There is a flow-guiding structure set inside the filter, whose function is to guide the high-flow media to be evenly distributed to each filter cartridge part, avoiding the influence on the filtration effect due to uneven local flow velocities. At the same time, a support structure is also set to fix the filter cartridges, prevent the filter cartridges from being deformed, displaced or even damaged under the impact of the high-flow media, ensure that the filter cartridges can stably play their filtering role, and ensure the normal progress of the filtration process.
Application Cases
