Here are some common types of pipeline filters:
Y-shaped filter
Structural features: The inlet and outlet are in a Y-shaped shape on the same horizontal line, with a filter inside, usually made of stainless steel or other materials. The accuracy of the filter can be selected according to needs.
Working principle: When the fluid flows through the filter, larger impurity particles are blocked on one side of the filter, and clean fluid flows out from the other side, thus achieving the purpose of filtration.
Applicable scenarios: Suitable for pipeline systems with various media such as water, oil, gas, etc., commonly used for coarse filtration, can be installed at the inlet or outlet of pipelines to protect subsequent equipment from damage caused by large particle impurities.
T-shaped filter
Structural features: Similar in shape to a "T", there are main and branch pipes, with filter screens installed on the branch pipes. There are various specifications for the accuracy of the filter screens to choose from.
Working principle: The fluid flows into the main pipeline, passes through the filter screen on the branch pipeline, and then returns to the main pipeline to continue flowing. Impurities are trapped in the filter screen, and regular cleaning of the filter screen can maintain the filtering effect.
Applicable scenarios: Widely used in liquid pipeline systems in industries such as chemical, food, and pharmaceutical, it can be used to filter solid particles, impurities, etc. in liquids, ensuring the purity of fluids.
basket filter
Structural features: mainly composed of cylinder, filter basket, flange, fasteners, etc. The filter basket is generally made of stainless steel material, with different pore sizes and filtration accuracies.
Working principle: When the fluid passes through the filter basket, solid impurities are intercepted by the filter basket, and clean fluid passes through the gaps of the filter basket to achieve the purpose of filtration.
Applicable scenarios: Suitable for liquid filtration in various industrial fields, such as water treatment, petrochemicals, papermaking, etc. It can be used to remove larger particle impurities, suspended solids, etc. from liquids.
self-cleaning filter
Structural characteristics: It is usually composed of components such as a motor, filter screen, scraper, and drain valve. The filter can be made of various types such as stainless steel wedge-shaped mesh, punched mesh, etc., with high filtration accuracy and strength.
Working principle: The motor drives the scraper to rotate, removing impurities attached to the filter screen and discharging them through the drain valve. Meanwhile, the clean fluid continuously passes through the filter screen, achieving continuous filtration.
Applicable scenarios: Suitable for working conditions with high filtration accuracy and high impurity content, such as circulating cooling water systems, sewage treatment, etc., which can effectively reduce manual maintenance costs and improve production efficiency.
Security filter
Structural features: Also known as precision filters, the filter element is usually made of materials such as polypropylene cotton, nylon, polytetrafluoroethylene, etc., with high filtration accuracy, generally between 0.5 microns and 100 microns.
Working principle: Utilizing the microporous structure of the filter element, the fluid is finely filtered to remove impurities such as small particles, bacteria, colloids, etc.
Applicable scenarios: Commonly used for pre protection of membrane separation systems such as reverse osmosis and ultrafiltration, as well as in industries with high water quality requirements such as food and beverage, pharmaceuticals, and electronics.
duplex strainer
Structural features: Composed of two filter units connected in parallel, each unit has an independent filter screen and inlet and outlet pipelines. Two units can be used alternately, and when one unit is working, the other unit can be cleaned or the filter can be replaced.
Working principle: The fluid is filtered through one of the filter units. When the filter screen of this unit is clogged or needs to be cleaned, it can be switched to another filter unit through a valve to continue working, ensuring the continuous operation of the system.
Applicable scenarios: Suitable for occasions with high requirements for continuous production, such as chemical production, pharmaceuticals and other industries, where filters can be maintained without stopping the machine.
Bag Filter
Structural features: mainly composed of filter bags, support baskets, containers, and other parts. Filter bags are generally made of materials such as non-woven fabric and nylon mesh, which have a large filtration area and good filtration performance.
Working principle: When the fluid passes through the filter bag, impurities are intercepted by the filter bag, and the clean fluid enters the next stage pipeline through the filter bag. The filter bag can be replaced regularly to meet different filtration accuracy and flow requirements.
Applicable scenarios: Widely used in liquid filtration in industries such as food and beverage, chemical, water treatment, etc., it can be used to remove small particles, suspended solids, etc. from liquids.
gas filter
Structural characteristics: Designed for gas media, porous ceramics, metal fibers and other materials are usually used as filter elements, which have the characteristics of high temperature resistance and corrosion resistance.
Working principle: When gas passes through the filter element, impurities such as solid particles and liquid droplets are intercepted by the filter element, and clean gas is discharged through the filter element.
Applicable scenarios: Mainly used for purifying compressed air, nitrogen, oxygen and other gases, removing impurities such as moisture, oil, dust, etc., to ensure the quality of gases and the normal operation of equipment.
Overall, these different types of pipeline filters have their own unique structures and working principles, suitable for different application scenarios and requirements. When selecting pipeline filters, reasonable selection should be made based on specific operating conditions (such as medium type, impurity content, filtration accuracy requirements, etc.) to ensure the effectiveness and economy of the filter
