Bag filtration equipment in the selection of filter bag considerations
Bag filtration equipment in the selection of filter bag considerationsAs we all know, in our modern society to use the many filtration equipment, bag filters are also quite popular, so here we come to introduce you to bag filtration equipment the selection of filter bags needs to pay attention to what problems, hurry to look at it with us!1, the filter performance of the filter media should meet the conditions of the production process and some special requirements, such as the temperature of the gas and dust, acidity and alkalinity, as well as whether there will be a risk of explosion and so on. 2, as far as possible to choose a longer service life of the filter media, so that not only can save the operating costs but also meet the requirements of the discharge standards; 3, when choosing the filter media should meet the conditions of the production process and some special requirements. 3, the choice of filter media should be a detailed comparison, choose the right one. 4, seize the main factors affecting the choice, such as high-temperature gas, flammable dust, etc.; 5, in addition to the above conditions. 5, in addition to the above conditions we also need to make economic comparisons. In addition to these factors, we can also be based on the need to filter the gas factors to choose from, mainly the following two aspects: 1, the temperature of the gas The temperature of the dust-containing gas is a very important factor, generally, we are less than 130 ℃ gas is called room temperature gas, and greater than 130 ℃ gas is called high-temperature gas, so the choice of filter media can also be divided into these two categories, that is, room temperature filter media and high temperature filter media. 2, the humidity of the gas Dust-containing gas according to its relative humidity can be divided into three categories: relative humidity below 30% of the time for the dry gas, between 30% - 80% of the general state, and more than 80% of the gas is highly humid. For high-humidity gas, when the period is in the high-temperature state, gas cooling will appear condensation phenomenon, which will make the surface of the filter bag scale, clogging, but also easy to corrode the material, these is also we need to pay extra attention to when choosing. Above we have detailed the selection of bag filtration equipment according to the various aspects of the different factors for you to consider the selection of the bag, our usual use of bag filters may be ignored, but we need to know that only by choosing the appropriate equipment, to make it play a big role in the use of the equipment! |
