When the pressure difference of the bag filter reaches the preset value, the automatic cleaning process will begin. During this period, the water supply continued, the cleaning valve opened, and the pressure inside the cleaning chamber and suction device significantly decreased, allowing the filter cartridge and suction port to pass through. The pressure difference between the straw and the clean room generates suction through the suction nozzle, forming a suction process.
When the accuracy of the bag filter mesh is not accurate, the filtering effect is greatly reduced, and impurities are not removed thoroughly. Only filters with sufficient accuracy can achieve the filtering goal. The accuracy of wedge-shaped mesh and perforated mesh can be customized, and enterprises should directly adopt customization when choosing.
When choosing bag filters, it is important to choose products with higher quality. Take the wedge-shaped network as an example. When selecting, you can observe whether the surface is smooth. Obviously, uneven filters have poor quality. When the scraper is running, it cannot be completed. Check if the filtering gap is uniform and the filtering accuracy is not high. Check the thickness of the filter screen. The wedge-shaped mesh holes are thinner and have a shorter service life.
At the same time, the motor drives the straw to perform axial spiral motion. The combination of axial and rotational motion of a vacuum cleaner can clean the entire inner surface of the filter. The entire flushing process only takes a few tens of seconds. At the end of cleaning, the drain valve is closed. The filter begins to prepare for the next flushing cycle.
Generally, circulating water, continuous casting water, agricultural irrigation water, and air conditioning water can all be filtered using bag filters, with accurate coverage, flexible flow control, and small footprint. Mechatronics integration. The traditional filter has now been replaced. But when choosing, please pay attention to the flow rate, concentration of suspended solids, and inlet pressure. If the concentration of suspended solids is high, pre-treatment must be carried out in advance. The inlet pressure should not be less than 3kg.
At present, the main types of bag filters on the market are V-shaped wedge-shaped screens and O-shaped perforated screens. Although the filtering accuracy of these two filters is relatively high, there are still significant differences. The V-shaped wedge-shaped screen has a smooth surface and a filtration accuracy of 30 microns, suitable for filtering liquids of various viscosities. Wear resistant, suitable for scraper type self-cleaning filters. Perforated mesh with higher accuracy, up to 10 microns. However, due to the uneven surface of the porous mesh, it is suitable for self-cleaning filters. Porous mesh cannot filter high viscosity liquids, it is only suitable for filtering water or liquids with viscosity close to water.
