Description :

　　Pulse single machine dust collector

　　The pulse single machine dust collector is a new type of high-efficiency pulse dust collector improved on the basis of the national standard MC. It combines the advantages of various pulse jet dust collectors with chamber back blowing, overcomes the disadvantages of insufficient cleaning intensity and uneven distribution of inlet and outlet air, and expands the application range. The structure of XMC dust collector has its own characteristics, which improve the dust collection efficiency, adaptability, and extend the service life of filter bags. After years of production practice, the equipment runs stably, has small maintenance requirements, and a wide range of combinations, and is highly praised by users. This series of products can be widely used for dust and smoke collection systems in asphalt mixing plants such as crushing, grinding, drying machines, furnaces, etc. The material of the dust collector filter bag is generally polyester needle punched felt, which allows continuous use at a temperature of ≤ 120 ℃. If the filter bag uses Metas high-temperature needle punched felt, its allowable use temperature can reach 204 ℃. This series of dust collectors can be combined with various specifications of electromagnetic valves according to different specifications. The dust collectors in this series can operate under negative or positive pressure without any changes to their body structure. The dust collection efficiency is over 99.8%, and the purified gas has a dust concentration of over 99.8%

　　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.

　　According to the actual design requirements of the project and the main structure design of the electrostatic precipitator equipment, the main focus is on the structural strength, stability, and displacement of the suspended cathode plate main beam. For local areas, the main focus is on the fatigue damage of the connection between the cathode plate and the main beam under long-term cyclic impact; Frequency selection of smoke and dust shedding on the cathode plate; The connection between the surface skin (thin plate) of the structure under wind load and the primary and secondary beams, as well as the selection of stiffness between them, etc
