Dust bag automatic production equipment

Description :

　　Fluid resistance

　　The U-shaped differential pressure gauge can be used to determine the operating condition: if the pressure difference increases, it means that the filter bag is clogged, there is condensation of water vapor on the filter bag, the cleaning mechanism fails, the ash hopper accumulates too much ash, causing blockage of the filter bag, and the gas flow rate increases. And a decrease in pressure difference means that the filter bag is damaged or loose, the inlet side pipeline is blocked, or the valve is closed. There are leakage phenomena or reduced fan speed between the box or compartments.

　　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.

　　advantage

　　⑴ The dust removal efficiency is high, generally above 99%. The dust concentration in the outlet gas of the dust collector is within tens of mg/m3, and it has a high classification efficiency for fine dust with sub micron particle size.

　　⑵ The range of air volume processing is wide, ranging from a few cubic meters per minute for small ones to tens of thousands of cubic meters per minute for large ones. It can be used for dust removal of flue gas in industrial furnaces and kilns, reducing the emission of atmospheric pollutants.

　　⑶ Simple structure, easy maintenance and operation.

　　On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of electrostatic precipitators.

　　When using high-temperature resistant filter media such as glass fiber, polytetrafluoroethylene, P84, etc., it can operate under high temperature conditions above 200 ℃.

　　(6) Not sensitive to the characteristics of dust and not affected by dust and resistance.
