Q:What are the factors result in lower efficiency bag filter ?

A:Bag filter is widely used in industrial dust, dust adsorption and purification have a good effect. Although we all know the function and role of bag filter, but if the bag filter dust removal efficiency is poor, what is causing it? Causes poor baghouse efficiency there are many, such as cleaning the system is not well designed, dust bag rupture, failure to use when procedures like, any details of which are likely to cause the effect of dust bag filter becomes difference. For these problems, we will have solved one by one. But before that, we must first understand the issues under the optional bag filter. Many enterprises in the purchase bag house, just about understanding the information will start to buy the next, so it is likely to cause errors. Because the current market there are different types of styles of bag filter, as for industrial air pollution control is not the same, the enterprise should be based on their actual work conditions to select the appropriate bag filter. For example, the concentration of smoke in the workplace, the ambient temperature, corrosive effects, etc. details. In addition, we also need to bag house quality inspection, the matter of the future bag house dust removal efficiency. If the quality of the bag filter itself is problematic, that effect will naturally be poor. Check the bag filter, we should pay attention to the details of technology and quality parts, such as housing and hopper there is a gap, it may cause leaks. Therefore, enterprises in the procurement and use of bag house time, according to standard working conditions and requirements select the appropriate filter. If that bag filter dust removal efficiency is poor, but also how to do it? First of bag house for investigation measures, first check whether there are loopholes in the bag or the bag has long service life, need to be replaced; Furthermore, is the entire injection system, comprising a pulse valve, cylinder, if there are several cabinet quality problems; and if the flue gas conditions change, can also cause deterioration of the treatment effect bag house, finally, that is a result of business irregularities. Enterprises in the purchase of bag filter, they must put the actual working conditions, such as flue gas temperature, corrosive and other details provided to the bag filter manufacturers, filter different operating conditions used in the structure and accessories use there is a difference. Not only the pursuit of lower costs, not to choose a suitable dust removal equipment. In acceptance of bag filter, it must be in strict accordance with relevant national standards for testing, because the effect of the work of bag filter, dust accessories will be some impact of the production process, such as the poor quality of the accessories, box and hopper no suture good, bag rupture, cleaning system failure, there may be leakage phenomenon which affects the effect of dust. Such as bag filter during use, the sudden appearance of dust effects of non-compliance situation, then one by one investigation shall be in accordance with the following recommendations: 1, check for broken bags or dust bag reach life 2, injection system (pulse valve, cylinder, cabinet) problems 3, flue gas conditions change, such as increasing the water content in the flue gas, flue gas volume increases and other Finally, when the bag house operation must be in accordance with the rules provided by the supplier, illegal operation may damage some of the parts, resulting in bag house dust is not ideal.
