　　Precautions

　　1. Inertial dust collectors, like gravity dust collectors, can be used separately or as pre dust collectors for multi-stage dust collectors.

　　2. The blades in inertial dust collectors are prone to wear and tear, and corresponding technical measures should be taken during manufacturing and application to extend their service life.

　　3. Reflux inertial dust collector is a commonly used type in practice, and is easy to configure and connect with dust removal systems. It has good dust removal effect and can also be used as a pre dust collector separately.

　　There are two ways to configure the louvered inertial dust collector when used alone: one is to install the dust collector behind the fan, and most of the gas is discharged through the dust collector shell, while a small part of the gas containing a large amount of dust is removed by the cyclone dust collector before entering the fan, implementing a sealed cycle to avoid discharging the dust removed by the cyclone dust collector. Its disadvantage is that dust passing through the fan can easily wear down its impeller; Another way is to install the dust collector in front of the fan, which can reduce the wear of dust on the fan impeller. However, the dust that has not been removed by the cyclone dust collector is directly discharged, resulting in lower dust removal efficiency.

　　5. Inertial dust collectors are highly sensitive to device air leakage, especially when air leakage from the casing, blades, etc. affects the flow of dusty airflow, resulting in a significant decrease in 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.

　　Factors affecting equipment pressure loss in dust collectors

　　(1) The pressure loss of a bag filter largely depends on the selected filtration wind speed. The resistance of the dust collector structure, the resistance of the cleaning filter material, and the resistance of the dust layer attached to the filter material all increase with the increase of the filtering wind speed.

　　(2) The dust accumulation load (m) has a decisive impact on the resistance of the dust filter material. Apart from directly affecting the size of △ Pd.

　　(3) Characteristics of filter media. The resistance of different structural filter media usually has the following relationship: long fiber filter media is higher than short fiber filter media; The non velvet filter material is higher than the velvet filter material; Textile filter media is higher than felt filter media; The filter material with heavier fabric is higher than the filter material with lighter fabric.

　　(4) Filter time. The resistance of the bag filter during operation is not a constant value, but varies over time.
