Description :

　　Painting process. The necessary condition for obtaining high-quality coatings is a coating process that fully utilizes the performance of coating materials. The painting process includes the rationality and progressiveness of the painting technology; Progressiveness of painting equipment and tools; Progressiveness and reliability of painting equipment and tools; The painting environment conditions and the skills and qualities of the painting operators.

　　mechanical force

　　Inertial dust removal equipment is a dust removal device that uses inertial force to separate and capture dust by causing the dusty gas to collide with a baffle or rapidly change the direction of the airflow. Inertial dust removal equipment, also known as inert dust removal equipment.

　　Inertial dust removal equipment is divided into two types: collision type and rotary type. The former is equipped with one or more baffles along the airflow direction, and the dusty gas collides with the baffles to separate the dust particles from the gas. Obviously, the higher the velocity of the gas before hitting the baffle and the lower it is after collision, the less dust it carries and the higher the dust removal efficiency. The latter is to make the dusty gas change direction multiple times and separate the dust during the turning process. The smaller the curvature radius of gas turning. The higher the turning speed, the higher the dust removal efficiency.

　　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.
