Since the introduction of bag dust collectors in China, after decades of development, there have been ultra-large bag dust collectors that can filter more than 5000 square meters, and even micro bag dust collectors with a filter area of less than 20 square meters. So many, how to choose the right bag type dust collector?
How to choose the right bag type dust collector? The first step is to master the dust removal conditions and determine the physical and chemical properties of the dust.
How to choose the right bag type dust collector? To install a bag type dust collector with good dust removal effect for an enterprise, the first step is to do a good job. The inevitable good start is half the success. We need to know the composition, temperature, corrosion, flammability and explosion of dusty gas. Look at the particle size, dispersion, grindability, and viscosity of the dust. The manufacturer of the bag filter should also remove the air volume of the dust collector. , Wind pressure, service life, installation requirements, etc. Finally, we should pay attention to whether the filtered flue gas concentration of the bag-type dust removal device meets relevant standards.
How to choose the right bag type dust collector? The second step: determine the dust removal method, choose the type of dust collector
As we all know, bag dust collectors can be divided into four categories according to the cleaning method: mechanical vibration cleaning, pulse cleaning, back blowing cleaning and composite cleaning. But so far, most of the bag type dust collectors using pulse injection, coupled with the popularization of high-temperature filters, have satisfied the effects of various pulse bag type dust collectors suitable for heating furnaces, and have attracted widespread attention. However, Fengbo Environmental Protection Network does not necessarily require you to choose a pulse bag dust collector here. This is just a reference. If it is used for dust removal in utility boilers, an electric bag composite dust collector may be required. Therefore, you also need to choose according to the working conditions, refer to the engineer's advice and choose the best.
Step 3: The choice of filter material is related to the service life of the filter bag.
One of the factors affecting the efficiency of dust removal is closely related to the filter material of the filter bag of the dust collector. When selecting the filter material of the filter bag, the physical and chemical characteristics of the dust-containing gas and the ash removal method of the selected equipment should be considered as much as possible. Fortunately There are a variety of filter materials, including needle felt, plastic film, woven fabric, fiberglass, etc. The correct choice will bring convenience to future maintenance.
How to choose the right bag filter? Step 4: Determine the filtering wind speed based on experience
When determining the filtering wind speed of the vacuum cleaner, it is necessary to consider the characteristics of the dust, the type of filtering material and the dust removal method. If the filtering wind speed of the selected filter is high, the treatment of particulates and viscous abrasive dust will be unfavorable. The filtering wind speed of wet gas and dust removal should not be too high. Like some filter materials with slightly higher resistance, the filtering wind speed can be appropriately increased, which needs to be determined according to the type of filter material.
Step 5: Calculate the filtering area of the vacuum cleaner
In general, when calculating the filtering area of a vacuum cleaner, you need to know the amount of air to be treated and the speed of the air to be filtered. This can be calculated by an engineer with many years of dust removal experience.
Step 6: Determine the cleaning cycle according to the actual situation
Due to the influence of various factors such as the dust removal method, soot characteristics, filter type, filter wind speed, pressure loss, etc., the relevant personnel must fine-tune the dust removal cycle, and master the spray cycle and pulse interval.
Step 7: Determine the type of dust removal equipment that needs to be customized
需要 袋式除尘器? 在这里，宇晨除尘设备厂家 提 醒您 如果你在清洗滤袋的时候需要切断过滤空气的流动，这里你通常指的是离线脉冲袋式过滤器，那么你也需要计算净过滤空气的速度. After the first six steps are completed, you can basically determine the need for a bag filter? Here, Yuchen dust removal equipment manufacturers remind you that if you need to cut off the flow of filtered air when cleaning the filter bag, you usually refer to the offline pulse Bag filters, then you also need to calculate the speed of the net filtered air.
