　　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.

　　To prevent Mars from entering the bag filter, the following measures should be taken:

　　① Set up pre dust collectors and cooling pipelines. Because cyclone dust collectors or inert dust collectors are used as pre dust collectors to capture coarse dust and sparks. Using this method, particles that are too fine are difficult to capture, and in most cases, the particulate dust can be burned off before entering the dust collector. Install cooling pipes after the pre dust collector and control the flow rate inside the pipes to keep it as low as possible. This is a relatively reliable technical measure that allows the gas to have sufficient residence time inside the tube.

　　② Cool down the spray tower. Gas cooling method of direct water spray in advance. To ensure the safety and fire prevention of the dusty gas inside the bag filter, the cooling water supply is controlled. Most of the burning dust can be cooled upon contact with fine water droplets, but water droplets are prone to gasification. In order to cool the burning dust that has not yet come into contact with water droplets, it is necessary to have sufficient space and residence time.

　　Under special circumstances, the combination of spray tower, cooling pipe and pre dust remover is used to completely prevent sparks from mixing.

　　③ The Mars capture device is shown in the figure. Installing a Mars capture device on the pipeline is a simple and feasible method. At the moment when Mars passes through the trap, it can emit an electrical signal to sound an alarm. At the same time, stop operating or change the gas circuit, etc.

　　Control the inlet dust concentration and add non combustible powder bag filter. During operation, the internal concentration distribution of the bag filter will inevitably make a certain part within the explosion limit. In order to improve safety, avoid the concentration between the upper and lower limits of dust explosion in the pipeline. For example, in dust collection work such as pneumatic conveying and crushing classification, attention should be paid from the design stage to operate at high concentrations exceeding the upper limit; In cases of local collection, it is necessary to maintain a low concentration of dust below the lower limit in the pipeline.

　　UF standalone dust collector is a small-scale bag filter that has been improved and pre-set. The material of the filter bag for UF single machine dust collector is considered suitable and chlorinated polyester needle felt is used. The operating temperature is less than 120 ℃, and the shaking device for shaking and cleaning has strong experience in cleaning. When the liquid concentration at the inlet is high, reaching 100g/Nm3, the liquid concentration at the outlet is 100g/Nm3, and the dust removal rate can reach 99.9%. UF single machine dust removal has the advantages of good dust removal effect, high purification rate, large disposal air volume, long lifespan of the filter bag, small maintenance and office workload, and reliable operation safety.
