With the continuous progress and development of the society, the living environment around us has changed a lot. There are also many different situations around us, such as the increase of dust, so we need dust collectors, and then a brief introduction to the working principle of dust collectors.

　　Filtration dust collectors include baghouse dust collectors and particle layer dust collectors. The former usually uses filter bags made of organic or inorganic fiber fabrics as the filter layer, while the filter layer of the latter is mainly composed of particles of different grain sizes such as quartz sand, river sand, ceramic grains and slag. As the powder repeatedly adheres to the outer surface of the filter bag, the powder layer thickens, and the resistance value of the bag filter increases; the pulse valve diaphragm sends out a command, the pulse valve opens, and the compressed air in the high-pressure air bag opens. If there is no dust or small enough, the mechanical dust removal work will stop.

　　Failure of the pulse valve rubber membrane is a common failure of the bag filter, which directly affects the dust removal effect. Equipment for the external filter type, bag inside the skeleton, check whether the fixed filter bag parts are slack, the filter bag tension is appropriate. Whether the support frame is smooth, to prevent wear and tear of the filter bag. Compressed air is used for dust removal. Therefore, in addition to oil mist and water droplets, the oil-water separator must be cleaned frequently to prevent failure of the moving mechanism and clogging of the filter bag. Whether the handling air volume, pressure and temperature are consistent with the design. The installation of the filter bag, whether there are off the bag, loose mouth, wear and tear after use, you can visually check the chimney discharge.

　　Prevent the gas from cooling below the dew point inside the bag, especially when using a baghouse under negative pressure. As the shell is often air leakage, so that the bag chamber gas temperature below the dew point, the bag will be wet, resulting in dust is not loose, but adheres to the filter bag, blocking the fabric holes, resulting in dust failure, so that the dust collector pressure is too high, can not continue to operate, and some of them produce a paste bag can not be dust removal. In order to prevent condensation, the temperature of the dust collector and its system gas must be higher than its dew point of 25 ~ 35 ℃ (such as kiln mill dew point temperature of 58 ℃, the working temperature should be more than 90 ℃), in order to ensure that the good use of the filter bag.

　　Gas cleaning: gas cleaning is the use of high-pressure gas or external atmospheric blowing filter bag to remove the ash on the filter bag. Gas cleaning includes pulse blowing, reverse blowing and reverse suction ash.

　　Mechanical vibration ash cleaning: divided into the top vibration ash cleaning and vibration ash cleaning (all for the filter bag). With the help of mechanical vibration device to regularly vibrate each row of filter bags in turn, to remove the dust on the filter bag.

　　Artificial knocking: Slap each filter bag by hand to remove the accumulated dust on the filter bag.

Through the above introduction about the working principle, use precautions and cleaning methods of the dust removal machine, I believe you will know what you should pay attention to when you use it. You can increase its home. Pay more attention to these issues when using it, correct service life and improve the quality of work.
