Matters needing attention when purchasing filter bags

Matters needing attention when purchasing filter bags: 1. There are many manufacturers that produce and distribute filter materials, and it is not uncommon for fish to mix beads; some bag filters are not well used, have low efficiency, and have a short lifespan, which has a lot to do with this. Therefore, to choose a certain filter material, it is necessary to know whether the production process of the manufacturer is complete, whether the product quality and testing methods are credible, and whether the sewing process is reasonable. In short, choose a good product. 2. The selection of a certain filter material depends on the conditions of use, in addition to the conventional dust concentration, dust fineness, flue gas temperature, moisture, emission requirements, strength characteristics of the filter material, etc.; also need to consider factors such as acid resistance, Chemical stability such as alkali resistance. At present, there is no cheap and good quality general filter material. For example, METMAX is a good filter material for cement clinker cooler dust removal, but it is not suitable for use in shaft kiln dust removal. 3. The filter wind speed is a very important parameter that determines the performance of the dust collector, and its value is directly related to the life of the filter material. So far, there is no formula to describe the relationship between it and various factors, but it is related to the characteristics of dust and flue gas, the method of cleaning dust, the material of filter material and fabric structure, and the size of investment and the economy of operation. Sex is related, so you need to choose carefully, and you must refer to many successful experiences and lessons from failure. 4. In addition to the characteristics, the selection of filter materials should also comprehensively evaluate its economy. It cannot simply be said that it is cheap and expensive. The price of filter materials should not only consider the initial investment, but also consider the economy of operation. For example, the price of film-coated needle-punched felt has increased several times compared with ordinary needle-punched felt, but under the same conditions of use, the running resistance can be reduced by half, which saves the power consumption of running; Area, no expansion of equipment, no need to start construction, you can get good feedback.
