The working principle of the plastic fired board dust collector is the same as that of the bag dust collector, except that the bag is replaced with a plastic fired board. The plastic fired board dust collector is mainly composed of an upper box, a middle box, an ash hopper, a spraying device, an ash unloading device, etc. The dust containing gas enters each bin ash hopper from the inlet pressure equalization pipe of the dust collector. Under the guidance of the ash hopper guide device, large particles of dust are separated and directly fall into the ash hopper. Fine particles of dust evenly enter the middle box and adsorb on the outer surface of the plastic burning plate. Clean gas penetrates the plastic burning plate and enters the upper box. And it is discharged into the atmosphere through various offline valves and exhaust pipes. With the improvement of filtering conditions, more and more dust will accumulate on the plastic fired board. The dust removal control device automatically closes the offline valve of the room based on the pressure difference setting value or dust removal time setting value, and then presses the setting value. Regularly open the electric pulse valve, stop the air injection, and use compressed air to instantly inject, increasing the pressure inside the plastic burning plate and removing the dust on the plastic burning plate(Even fine dust can be completely removed) thrown into the ash hopper and discharged through the ash discharge mechanism.
The plastic fired plate dust collector uses a unique wave shaped plastic fired plate filter element instead of traditional cloth bags. Due to the rigid structure of the plastic fired plate, it will not deform and there is no skeleton wear, so its service life is long. Under some working conditions, its service life is longer than that of cloth bagsMore than 10 times. Due to the deep treatment of the surface of the plastic fired board, the pore size is small and uniform, it has hydrophobicity, and is not easy to adhere to dust with high moisture content. Therefore, a plastic fired board dust collector is the best choice when dealing with dust with high moisture content and fibrous dust. In addition, due to the high-precision manufacturing process of plastic fired plates, uniform micron sized pore sizes are maintained, which can also handle ultrafine dust and high concentration dust. The inlet concentration of bag filters is generally less than 20 grams/m3, while the inlet concentration of plastic fired plate dust collectors can reach 500 grams/m3. It can simplify secondary dust collection into primary dust collection, which not only facilitates the process, but also reduces cost and energy consumption, and reduces the footprint and space pipeline.
Plastic fired board is a surface filtration method with high dust removal efficiency, and the emission concentration is usually lower than10mg/m3, also has good dust removal effect on fine dust particles; Compact equipment structure and small footprint; Due to the rigid body of the plastic fired board, it will not deform and has minimal wear on the steel frame, resulting in a long service life, approximately 2-4 times that of the filter bag; The surface and pores of the plastic fired board are treated with fluorinated resin, and the inert resin is completely hydrophobic. It not only does not adhere to dry dust, but also is not easy to bond to dust with high moisture content. Therefore, the plastic fired board dust collector is a good choice for treating high moisture or oil content dust; Price of plastic fired board dust collectorMore expensive,onlyProcessing the same air volume as a bag filter2-6 times. Due to its structure and surface coating, the plastic fired plate dust collector can perform well in situations where other dust collectors cannot be used or are not used properly.
Although the filter elements of the plastic fired plate dust collector require almost no maintenance, in special industries such as color variety replacement during pigment production, paint replacement during spraying operations, and regular disinfection during pharmaceutical instrument production, the filter plates need to be removed for cleaning. At this point, the special structure of the plastic fired plate dust collector will make this task very easy. Operators can operate it outside the dust collector by removing two bolts to replace a filter plate, fundamentally improving the working conditions.
The plastic fired board dust collector has high dust collection efficiency. The capture efficiency of plastic fired board is achieved by its unique structure and coating, which is different from the high efficiency of bag filter and is based on the secondary filtration of adhered dust. From the actual test data, it can be seen that in general, the dust concentration in the exhaust of the dust collector can be maintained atBelow 2mg/m3. Although the emission concentration is related to the inlet concentration of dust containing gas and the particle size of dust, the capture efficiency of ultrafine dust below 2 μ m can still be maintained at 99.9%.
