　　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.

　　Filter media:

　　Suitable for temperatures ranging from room temperature to 250 ℃, equipped with a cooling section that can handle smoke, oil, and water up to 1000 ℃, withstand dust and moisture up to 35%, and air relative humidity up to 95%.

　　Not easy to stick to dust, capable of withstanding dust concentrations up to 300g/m3 (with a settling chamber capable of withstanding dust concentrations up to 1000g/m3), high mechanical strength, high air permeability at filtration speeds of 1-3 meters per minute, and filtration resistance of 500-1500Pa.

　　Model Description: DLM C a/b/15

　　DLM pulse cleaning flat bag dust collector; C modular box structure; Number of columns a, number of left and right filtering modules in the dust collector; B layers, number of filtering modules in the vertical direction of the dust collector; The filtration area of 15 dust collector modules

　　Basic parameters of DLMC modular flat bag dust collector

　　The initial investment of boiler electrostatic precipitator is large, but it is easy to maintain.

　　An electrostatic precipitator is a device that uses strong electric field corona discharge to ionize gas, charge dust particles, and separate them from the airflow under the action of Coulomb force. The characteristics of an electrostatic precipitator are high dust removal efficiency, the ability to handle high-temperature gases, low resistance, and low operating costs. However, it requires high steel consumption, high cost, and high technical requirements.
