Manufacturers offer discounts on bag cyclone dust collectors for Quanzhou bag dust removal equipment

Description :

　　The dusty gas first enters the high-efficiency solid upper stable vortex reverse mass transfer washing chamber in a tangential direction. The flue gas is cooled and saturated by an alkaline solution, and large particles of dust and sulfur dioxide are absorbed and washed off for the first time. Then, due to differences in mass and inertia, the three-phase airflow of flue gas, water mist, and dust transfer to each other and enter the high-efficiency coagulation atomization washing chamber for contraction, rapid aggregation, diffusion, and other motion effects, and are desulfurized and dedusted for the second time. Subsequently, the three-phase airflow of flue gas, water mist, and dust impacts the high-efficiency circulating fluidized filtration chamber containing alkaline solution at a certain rate through sufficient impact, turbulence, stirring, filtration, mass transfer and other motion mechanisms, and is desulfurized and dedusted for the third time, At this time, the relatively clean flue gas enters the high-efficiency stable cyclone reverse mass transfer washing room in a tangential direction, and undergoes reverse mass transfer motion through alkaline liquid film and liquid mist for the final desulfurization and dust removal. The purified clean flue gas enters the high-efficiency dehydration and defogging room for gas-liquid separation treatment, and is sent by the induced draft fan to the chimney for discharge into the air.

　　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.

　　Dust collectors are divided into the following five categories based on their operating principles:;

　　(1) Mechanical dust collectors include gravity dust collectors, inertial dust collectors, centrifugal dust collectors, etc.

　　(2) The scrubbing dust remover includes water bath dust remover, foam dust remover, Venturi tube dust remover, water film dust remover, etc.

　　(3) Filter type dust collectors include bag filter and granular layer filter, etc

　　(4) Electrostatic precipitator.

　　(5) Magnetic dust collector.
