Manufacturer supplies polishing dust vacuum cleaner quality Quanzhou bag dust removal equipment

Description :

　　The use of a Venturi tube is the most common inertial impact wet dust removal method, but other methods can also be used. One of the methods is to use spray towers with different designs (such as concurrent flow (concurrent flow), countercurrent flow (countercurrent flow), cross flow, etc.). These dust collectors are effectively applied in various situations where the required capture efficiency can be achieved at low energy consumption, usually in situations where the dust particles are large or the dust removal efficiency requirements are low.

　　Product Maintenance

　　Regularly check the operation of control valves, pulse valves, and timers.

　　The failure of the pulse valve rubber diaphragm is a common fault in bag filters, which directly affects the dust cleaning effect. This device belongs to the external filter type, with a skeleton inside the bag. It is necessary to check whether the parts that fix the filter bag are loose and whether the tension of the filter bag is appropriate. Is the support frame smooth to prevent wear and tear on the filter bag. Compressed air is used for dust removal. Therefore, it is required to remove oil mist and water droplets, and the oil-water separator must be cleaned regularly to prevent malfunction of the moving mechanism and blockage of the filter bag.

　　Whether the air volume and pressure and temperature at each testing point are consistent with the design.

　　The installation status of the 3 filter bags, whether there are any occurrences of bag dropping, loosening, wear, etc. after use, can be judged by visually observing the emissions of the chimney after operation.

　　4. Prevent condensation

　　During use, it is necessary to prevent the gas from cooling below the dew point in the bag chamber, especially when using a bag filter under negative pressure. Due to the frequent leakage of air into the outer shell, the gas temperature in the bag chamber is lower than the dew point, causing the filter bag to become damp. This results in dust not being loose but sticking to the filter bag, blocking the fabric holes and causing dust removal failure. This leads to excessive pressure drop in the dust collector, making it unable to continue operating, and some bags may become stuck and unable to remove dust.

　　To prevent condensation, it is necessary to maintain the temperature of the gas in the dust collector and its system at 25-35 ℃ above its dew point (such as the dew point temperature of 58 ℃ for kiln mill integrated machines, and the operating temperature should be above 90 ℃), in order to ensure the good use effect of the filter bag.

　　Bag filter is the choice with high purification efficiency and good dust removal effect among all dry dust removal equipment. In recent years, with the rise of new filter media and pulse back blowing dust cleaning technology, bag filter and bag pulse dust collector have made great progress. Bag filter is one of the most widely used dust removal equipment with high purification efficiency and good dust removal effect among all dry dust removal equipment. It has been many years since the emergence of the Taiwan bag filter, but the development of bag filters has been slow. Previously, the filter material was made of natural fibers such as coarse cloth, burlap, and wool, sewn into smaller pockets. The dust collector body is mainly welded with steel plates, and the scale is mostly to process several thousand cubic meters of gas per hour. The cleaning method used to include mechanical vibration, hand crank vibration, and reverse blowing. In places where powder needs to be recycled and produced, due to the high air volume, there have been simple large-scale hanging bags with brick air ducts and the entire house as the bag room. The simple cleaning method used regular manual tapping. In recent years, due to the rise of new filter materials and pulse back blowing dust cleaning technology, bag filters have made a leap forward in development. Nowadays, bag filters have a wide variety of specifications, high degree of automation, and easier maintenance and management. Especially prominent on large bag filter equipment. Bag filters can now be used domestically to purify various types of dust with different properties, such as viscous dust, high-temperature gas dust, high humidity gas dust, and air containing ultrafine dust. Bag filters are very suitable for capturing fine dust and can easily adapt to different dust concentrations, particle size distributions, changes in dust conductivity, and can be selected according to the required air volume for processing.
