There are many factors related to the service life of the boiler dust bag, first of all, the dust bag itself will have its own service life, generally ranging from 1-4 years, depending on how to use, and how the material of the dust bag itself is. For example, the use of dust bag material, you need to choose the right temperature according to different factory conditions to produce, can not be high temperature industry with low temperature bags to use. Also take into account the different working conditions for the bag is also different factors, as well as the humidity situation within the bag and the surrounding environment temperature situation will affect the service life of the dust bag, etc. 1. The humidity situation of the dust bag The condensation of water vapor in the filter bag room is due to the cooling of moist gas, especially the gas generated by combustion, the need to remove the moist gas before the system cooling, replaced by dry air to prevent damage and corrosion of the filter bag and dust removal body, increasing the life of the bag. 2. Use the surrounding environment of the dust bag In such an environment will easily condensation phenomenon, should be the system of moisture out of the box after sealing. If it is the next period of time will not use the equipment is required to take out the bags, stored in the warehouse. 3. Different dust filter bags of different materials will also affect the length of use of the product According to the dust collection temperature dust collector can be divided into room temperature dust collector and high temperature dust collector, room temperature and high temperature bag supporting materials are different, the service life is not the same. 4. Different industries use different working conditions, for the use of bags when the loss is also different. The degree of damage caused by different working conditions is also different. If it is high temperature, strong corrosive environment, the bag will be easily damaged, the replacement time will be longer, if it is used at room temperature, low corrosive environment, the bag does not easily suffer damage, the replacement time will be longer.

The working temperature range of denitrification catalyst is 320--360℃. The core of SCR denitrification technology is the denitrification catalyst. Currently, there are three main types of catalysts used in industry, namely honeycomb, flat plate and corrugated plate, all of which must operate stably under certain temperature conditions. The common temperature in power plants is 300~426C, which is too low for the catalyst to react with NH3, and too high for it to sinter and become less active or even scrap. There are two main reasons why conventional denitrification catalysts cannot operate at low temperatures: 1) the temperature is too low to achieve the reaction conditions and the catalyst is ineffective; 2) the catalyst activity decreases under low temperature conditions. The application of low temperature SCR denitrification catalysts becomes more difficult than the above 2 points. Denitrification catalyst is the core part of SCR technology, which determines the denitrification efficiency and economy of SCR system, and its construction cost accounts for more than 20% of the flue gas denitrification project cost, and the operation cost accounts for more than 30%. In recent years, developed countries such as the US, Japan and Germany have continuously invested a lot of human, material and financial resources in research and development of high efficiency and low cost flue gas denitrification catalysts, paying attention to the protection of intellectual property rights in the process of catalyst patent technology, technology transfer and production licensing. The initial denitrification catalysts were metal-based catalysts such as Pt-Rh and Pt, with monolithic ceramics such as alumina as the carrier, which had the characteristics of higher activity and lower reaction temperature, but the expensive price limited their application in power plants.   With the continuous research and development of technicians, Yuanchen Technology has designed and developed medium and low temperature denitrification catalysts with stable and reliable denitrification performance in the range of 160-380°C, achieving low temperature and high activity.   The technology has won the national science and technology achievement certificate, Anhui Province new products and other awards; the products are widely used in domestic steel sintering machines, coking, white ash kilns.

Yuanchen Technology reveals AR-21 gel silica-based super wear-resistant filter media During the operation of bag filter, due to unreasonable design of dust removal system, improper installation, unreasonable setting of operating parameters, filter material and other reasons, it may cause the filter bag to break and fail, which in turn affects the service life of the filter bag, the operating status of the dust collector and the emission of particulate matter. The reasons for the breakage of the filter bag during operation are chemical damage (acid and alkali corrosion, oxidation and hydrolysis, etc.), airflow scouring (inside and outside the bag) and mechanical friction, etc. Figure1 Old bag breakage situations Figure 2 2021 annual testing center old bag failure detection analysis results According to the year 2021 Anhui Confair Testing Technology Co. Ltd. (CNAS, CMA ) old bag failure detection analysis results can be seen, as shown in Figure 2 above, excluding the dew paste bag phenomenon caused by the working conditions, where the number of broken filter bags is the most, and the main reason for the broken filter bag is the friction between the bag and the filter bag. The highest percentage of filter bag breakage is caused by friction between bag and bag, accounting for 70% of the broken bags; so the effective method to improve the wear resistance of filter bags will effectively delay or avoid the failure of breakage caused by friction and extend the service life of filter bags. In order to solve the pain points of customers and fundamentally improve the wear resistance of filter media, our technical advantages are. 1. Double-layer bag bottom strengthening technology. 2.

Many manufacturers do not know how to choose the filter bags, many times because there is no professional technical personnel, and even the measurement of the bag is not good. Remember a customer got it wrong, resulting in the bag and the bag cage installed mismatch, and finally found that the bag cage can not be set in, so that the final dust bag no way to use again, back and forth to transform the cost is higher, very troublesome. Some customers bought the dust bag, after using the time is not long on the wear and tear, these problems are because we correctly choose a good dust bag, then how to choose it? Look at the following introduction of our Yuanchen technology. 1. first of all, we need to understand our factory working conditions, and then combined with the characteristics of the dust bag, find the dust bag to match the working conditions. This time it is necessary to understand the type of working conditions, specific engaged in what manufacturing, what fuel is used, what is the main gas, etc. to consult the situation. 2. professional measurement of the size of the bag, if you can measure the natural better; if you can not measure, you must find the manufacturer specializing in dust bag for guidance and help measurement. 3. the filter cloth should not be hung too loose or too tight, too loose easy to accumulate dust, too tight easy to pull bad.

Dust filter media is an important material for dust filter bag, and the different types of filter bags mainly depend on the different filter media of the bags. Dust filter bag is a kind of high efficiency dust filter media, dust filter bag is taken PPS fiber, Aramid fiber, polyester staple fiber, etc. as raw material. It has good air permeability, high dust collection rate, easy to clean dust and dust removal efficiency up to 98.99%. The selection of dust filter media can be based on the nature of the dust containing gas; or the shape of the dust to select the filter media. 1. The selection of dust filter media is based on the shape of the dust, the particle size of the dust, the hygroscopicity and adhesion of the dust, and the explosivity of the dust. 2. Selecting dust filter media by dust gas can be judged by the temperature, corrosion resistance, humidity and other aspects of the filter media. In short, when choosing dust filter media, we can choose from high concentration dust collection process, high standard emission and purification requirements, stable and low resistance operation requirements, oil mist and other viscous fine dust gas treatment and special structure dust collector requirements.
