The cardboard filters working principle is always decided by the structure. The valve inlet is generally installed in the equipment entrance. When the gas flows through the valve into the processing equipment, the cardboard filters can filter out the gas pollution of impurities in time. This not only has the effect of protection of production equipment, but also effectively reduces the pollution gas emissions. Now many manufacturers are using cardboard filters and this also led to too many types of filter which are in order to meet the needs of the manufacturers filtering gas and clean pollution.
The specific cardboard filters working principle is not complex. Water for treatment of cardboard filters will flow from water entry into the filter body. The impurities in the water will deposit in stainless steel mesh which can result in differential pressure. Through differential pressure the switch can monitor the nozzle pressure difference change. On the other hand, when the differential pressure achieves set data, control device for hydraulic control valves and motor drive signal will cause the following action, such as motor driving brush rotation and the filter cleaning. The emission control valve will open at the same time. The whole cleaning process only lasts for dozens of seconds. At the end of the cleaning, we should close the valve and the motor will stop running. Also the system of cardboard filters can be back to its initial state and begin to filter into the next process.
In the cardboard filters cylinder body, filter material of different particle sizes will be lined by size compaction. When water flows to the downstream filter layer, the suspended material water containing will flow into the upper form tiny pore. Affected by adsorption and mechanical choke, the cardboard filters material surface layer will get interception. At the same time, these trapped solids will get overlap and bridge role forming a thin film in the surface of cardboard filters. And air filtering will continue to happen. This in cardboard filters working principle is known as filter material surface membrane filtration effect. This kind of membrane filtration effect is mostly on the surface. And when the water flows into the middle filter material layer, it can also produce the intercept. With the effect, the intercept action is called osmosis filtration effect.
