Price of Quanzhou bag dust removal equipment supplied by the manufacturer for boiler bag dust collectors

Description :

　　The gas purification method of the low-pressure pulse bag filter is external filtration. The dusty gas enters each unit filtration chamber through a guide pipe. Due to the design, there is sufficient and reasonable airflow from the bottom of the filter bag to the upper opening of the air inlet through appropriate guidance and natural flow distribution, achieving uniform air distribution throughout the filtration chamber. The particulate dust in the dusty gas is separated by natural settling and directly falls into the ash hopper, while the remaining dust is guided by the guide system and enters the middle box filtration area with the airflow, adsorbing on the outer surface of the filter bag. The filtered clean gas passes through the filter bag and is discharged through the upper box and exhaust pipe.

　　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.

　　Biological nanofilm

　　Biological nanofilm dust removal equipment is a dust removal device that has emerged abroad in recent years. It utilizes the advanced technology of biological nanofilm and sprays BME nanofilm onto the surface of materials to effectively suppress the generation of dust during production and processing. This type of dust removal technology belongs to pre emission dust removal, which has great advantages compared to other post production dust removal methods, enabling effective control of dust emission throughout the entire material production process. The dust generated during the crushing process aggregates into fine materials, ultimately becoming finished products, which can increase production by 0.5% -3%. In addition, it can effectively prevent PM2.5 and PM10 pollution, in line with relevant national environmental protection and energy conservation and emission reduction technology policies. Compared with wet dust removal and bag dust removal, biological nanofilm dust suppression has no water pollution, no side effects on the environment, no impact on the quality of finished materials, and lower investment costs. It is suitable for dust pollution control in mines, buildings, quarries, yards, ports, thermal power plants, steel plants, garbage recycling and treatment sites, and other places. Nano film dust removal has been applied in different ways overseas, and is gradually being applied in many provinces and cities in China.
