Filter cartridge

Filter cartridges, also known as filters, are a common type of industrial equipment. It is usually used to remove impurities from liquids or gases, making them more pure. The design and use of filter cartridges are very extensive and important. This article will provide a detailed introduction to the basic principles, classification, working principles, and application fields of filter cartridges.

1、 The basic principle of a filter cartridge is to use its internal filter element to filter out impurities in liquids or gases and purify them. The filter cartridge is usually made of fiber materials, metal wire mesh, porous ceramics, and other materials, which have good filtration performance. When liquid or gas passes through the filter cartridge, impurities will be blocked by the filter element, while clean liquid or gas will flow out through the filter element.

2、 The classification of filter cartridges can be divided into many types based on their different characteristics and uses. Common filter cartridge classifications include: pressure filter cartridge, vacuum filter cartridge, centrifugal filter cartridge, sand filter cartridge, activated carbon filter cartridge, etc. Each type of filter cartridge has different characteristics and application scenarios, and suitable filter cartridges can be selected according to specific needs.

1. Pressure filter cartridge Pressure filter cartridge is a widely used filter cartridge. It is usually installed in a pipeline, and impurities are pushed through the filter cartridge through the pressure of the liquid or gas inside the pipeline to achieve filtering effect. Pressure filter cartridges are suitable for filtering liquids or gases in scenarios such as chemical, power, and petroleum industries.

2. Vacuum filter cartridge Vacuum filter cartridge uses negative pressure to adsorb impurities from liquid or gas onto the surface of the filter element, and then uses other methods to clean the contaminated filter element. Vacuum filter cartridges are mainly used for filtering viscous or high concentration liquids, such as in industries such as pharmaceuticals and food processing.

3. Centrifugal filter cartridge Centrifugal filter cartridge is a type of filter cartridge that uses centrifugal force to separate impurities from liquids or gases. It usually involves rotating the filter cartridge to deposit impurities in the liquid or gas on the filter element wall, and then cleaning the filter element through other methods. Centrifugal filter cartridges are suitable for filtering liquids or gases with large suspended particles, such as in industries such as paper making and pulp making.

4. A sand filter cartridge is a filter cartridge that filters liquids or gases through a thick layer of sand. It uses the pores in the sand layer and the gaps between sand particles to block impurities and purify liquids or gases. The sand filter cartridge is suitable for filtering larger particles or impurities with higher concentrations, such as water treatment, sewage treatment, etc.

5. Activated carbon filter cartridge Activated carbon filter cartridge is a type of filter cartridge that uses activated carbon materials to adsorb organic substances in liquids or gases. Activated carbon materials have good adsorption performance and can effectively remove odors, harmful substances, etc. from liquids or gases. Activated carbon filter cartridges are suitable for filtering liquids or gases containing organic pollutants, such as water treatment, air purification, etc.
