The principle of stainless steel filter


Stainless steel filter is a device used to filter impurities in liquids or gases, mainly made of stainless steel material. Its working principle is mainly to use the microporous structure inside the filter element to intercept impurities in liquids or gases through physical filtration. When liquid or gas flows through the filter, impurities will be blocked by the filter element, while pure liquid or gas will pass through the filter element unobstructed and be discharged from the outlet pipe.


Specifically, stainless steel filters typically include a housing, a multi-element filter element, a backwash mechanism, and a differential pressure controller. During operation, the turbid liquid enters the lower chamber of the filter through the inlet and then enters the inner cavity of the filter element through the partition hole. Impurities larger than the gap of the filter element are intercepted, and the clean liquid passes through the gap to reach the upper chamber, and finally is sent out from the outlet. When impurities accumulate on the surface of the filter element, causing the pressure difference between the inlet and outlet to increase to the set value, or when the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism for cleaning to ensure the continuous and efficient operation of the filter.


Application of Stainless Steel Filters


Stainless steel filters have become an indispensable part of the industrial sector due to their excellent performance and wide range of applications. Its specific applications include but are not limited to the following aspects:


Chemical industry: Stainless steel filters are widely used in the production and processing of various chemicals in industries such as petroleum, petrochemicals, and fertilizers. They effectively remove impurities and particulate matter from fluids, ensuring product quality and production continuity.


Pharmaceutical industry: Stainless steel filters are one of the essential equipment in the production and packaging process of drugs. It can filter impurities and particles in the medicine, ensuring the quality and safety of the drug. Meanwhile, its corrosion resistance and high lifespan also reduce the equipment replacement costs for pharmaceutical companies.


Food and beverage industry: In the production and processing of products such as drinking water, juice, beer, etc., stainless steel filters can effectively remove impurities and particles from the fluid, ensuring the quality and taste of the products. Its easy to clean feature also facilitates the daily maintenance and cleaning work of enterprises.


Electronics industry: In the manufacturing and processing of semiconductor, integrated circuit and other equipment, stainless steel filters can provide a clean fluid environment, ensuring the normal operation of equipment and the quality of products.


Water treatment industry: Stainless steel filters can remove impurities and particulate matter from water and improve water quality in processes such as sewage treatment and drinking water treatment.


Environmental protection industry: In environmental protection projects such as exhaust gas treatment and flue gas desulfurization and denitrification, stainless steel filters can remove harmful substances and particulate matter from exhaust gas, achieving the goal of purifying the air.


Energy sector: In the production process of fuel ethanol, stainless steel filters can remove impurities and harmful substances from ethanol, improving the quality and safety of ethanol.


In other fields such as shipbuilding and seawater desalination, stainless steel filters also play an important role. In the shipbuilding industry, it is used in the water supply system, lubricating oil system and other parts of ships; In the process of seawater desalination, it can remove salt and other impurities from seawater to obtain drinkable fresh water.


Above all, stainless steel filters play an important role in modern industry due to their excellent performance and wide range of applications.
