　　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.

　　Advantages of small boiler dust collector:

　　1. New wind energy cooling system; It is developed by our company after years of experience accumulation, combined with the actual working conditions of coal-fired boilers. Under the principles of advanced technology, reliable operation, and economic rationality, in order to minimize one-time investment, save energy and reduce consumption, and facilitate system maintenance to the greatest extent possible. The lifespan and work efficiency of the overall equipment play a very important role.

　　2. Premium bag filter; The bag filter is a dust collector designed by our factory after digesting and absorbing the advantages of similar products at home and abroad, and after improvement. The dust collector adopts a pulse jet cleaning method, which has the advantages of good cleaning effect, high purification efficiency, large processing air volume, long filter bag life, small maintenance workload, safe and reliable operation, etc! Whether in terms of appearance or quality of the equipment, our company's bag filter is a leader in the industry and a model for our peers to emulate. Strive for excellence, with superior quality!

　　3. Fiberglass high-efficiency desulfurization tower; Considering that sulfur dioxide forms sulfuric acid when it comes into contact with water, it has strong corrosiveness to all metal materials. Our company has conducted research, investigation and experimentation during the Chinese New Year, and has adopted a desulfurization tower made of fiberglass material. Fiberglass has the advantage of resisting strong acids and alkalis, and will not corrode after 10 years of desulfurization. Whether it is carbon steel or stainless steel desulfurization tower, the service life will not exceed 1 year. Indirectly saving customers a lot of money.

　　Equipment design editing filter element

　　Filter elements can be made of cotton wool fibers, glass fibers, or various chemical fibers that are woven (or needle punched) into filter media, and then sewn into vertically suspended filter bags. Different filter media should be selected for different occasions. The dust collected on the filter bag is removed by deforming the bag through periodic mechanical shaking, filtered flue gas blowback, or compressed air pulse blowback.

　　The filter cake (filter bed) formed by the passage of flue gas through the filter bag and filter material surface relies on the pressure difference on both sides of the filter layer - this pressure difference is usually referred to as the tube plate pressure difference d.p. (sometimes also referred to as the filter bed pressure difference). In fly ash collection, a special parameter is the filtering smoke velocity - the amount of air filtered per minute per square meter of filter cloth. The pressure difference d.p. of the filter bed is linearly proportional to the smoke velocity, and therefore also linearly proportional to the smoke flow rate.

　　This fixed proportional relationship coefficient is commonly referred to as filter resistance. According to this definition, filter resistance is independent of flue gas flow rate and is somewhat similar to the concept of resistance. We represent the average filtration speed as the gas to cloth ratio, which is the ratio of flue gas volume to the entire filtration area (expressed in m3/m2/min). This parameter is a very important technical indicator in the selection and design of bag dust removal equipment.
