Structural Composition
Dual Filtration Units: Consists of two parallel filter tanks, each equipped with high - precision micro - pore filter elements. They can work independently or in coordination, enhancing filtration efficiency and processing capacity.
Switching Valve Group: Includes inlet switching valves, outlet switching valves, and drain valves. The valves enable the alternate operation and cleaning of the filtration units through switching.
Outer Shell: Made of stainless steel 304 or 316L, it has excellent corrosion resistance and strong pressure - bearing capacity, suitable for various working conditions.
Pressure Gauge and Flowmeter: Monitors the inlet and outlet pressure and flow rate of the filtration units in real - time, facilitating the grasp of the equipment's operating status.
Working Principle：The fluid to be filtered enters the filter through the inlet pipe and is distributed to one of the filtration units by the switching valves. Under pressure, the fluid passes through the porous filter element, and impurities are intercepted on the surface of the element. The clean fluid is discharged from the outlet. When the filter element of a certain filtration unit is blocked, causing an increase in pressure difference or reaching the set operating time, the fluid can be introduced into the other unit by switching the valves, and at the same time, the blocked unit can be cleaned or the filter element can be replaced, achieving uninterrupted filtration.
Core Advantages：Compared with single - unit filtration equipment, the double - unit micro - pore precision filter realizes continuous and uninterrupted filtration through the alternate operation of the two units. The high - precision filter elements can intercept micron - level particles, meeting high - cleanliness requirements. The modular design facilitates maintenance and filter element replacement, reducing downtime and maintenance costs.
Initial Filtration
Open the main inlet valve and the inlet and outlet valves of one of the filtration units, and close the valves of the other unit.
The fluid to be filtered enters the opened filtration unit, is filtered by the micro - pore filter element, and the impurities are intercepted. The clean fluid flows out from the outlet to downstream equipment.
Unit Switching
When the pressure difference between the inlet and outlet of the operating filtration unit exceeds the set value (such as 0.1 - 0.15MPa), or reaches the preset operating duration (such as 8 - 24 hours).
Close the inlet and outlet valves of this unit, and at the same time, open the inlet and outlet valves of the other filtration unit, so that the fluid is switched to the new unit for continuous filtration.
Filter Element Maintenance
For the filtration unit in need of maintenance, open the drain valve to discharge the residual fluid inside.
Remove the end cover of the tank, take out the blocked filter element for cleaning or replace it with a new one.
Install the new filter element, seal the tank, close the drain valve, and wait for the next switch to be put into use.
Continuous Operation：The two filtration units repeat the above process alternately to ensure the continuous fine filtration of the fluid.

How to select the appropriate filter element precision for the double - unit micro - pore precision filter?：It is necessary to determine according to the particle size of impurities in the fluid and the cleanliness requirements of downstream equipment. For example, in the electronics industry for producing high - purity water, a filter element with a precision of 0.1 - 0.5 microns is usually required; for food and beverage filtration, a filter element with a precision of 1 - 5 microns can be selected. At the same time, consider the impurity content. If there are many impurities, a filter element with a lower precision can be used for pre - filtration first, and then a high - precision filter element for secondary filtration.
What should I do if the pressure difference increases abnormally during the equipment operation?：An abnormal increase in pressure difference may be due to severe blockage of the filter element. In this case, the filtration unit should be switched in time, and the filter element of the blocked unit should be cleaned or replaced. It may also be that the valve is not fully opened or the pipeline is blocked. The valve status and pipeline patency need to be checked. If the filter element is damaged, causing impurities to enter the downstream and blockage, the damaged filter element needs to be replaced, and the downstream equipment needs to be cleaned.
