　　operation log

　　Each ventilation and dust removal system must be equipped with necessary testing instruments, which must be regularly measured and accurately recorded during daily operation. This allows for judgment based on the system's pressure difference, inlet and outlet gas temperature, main motor voltage, current, and other values and changes, and timely troubleshooting to ensure its normal operation.

　　The problems discovered through recording include: the working condition of the dust cleaning mechanism, the working conditions of the filter bag (such as damage, bag sticking, blockage, etc.), and changes in the system air volume.

　　Industry specific business model

　　Bag filter is the core equipment in the dust removal system, with strong system design and configuration, and a high degree of personalization in customer needs. Generally, customization is required for specific application scenarios. Production enterprises in the industry generally obtain orders through bidding, and organize product design, production, installation, and commissioning according to user needs. Production enterprises are mainly responsible for designing and producing core components, while supporting parts are obtained through procurement from manufacturers; Production enterprises assemble various core components and supporting parts into products according to order requirements. In this mode, the production of core components is carried out internally within the manufacturing enterprise, ensuring control over technical know-how and implementing strict quality control processes according to high quality standards. Product quality can be effectively guaranteed, but due to limited production capacity, the ability to undertake orders is somewhat restricted.

　　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.
