In addition to the correct selection of filter bag materials, the dust removal system plays a decisive role in the performance of the central dust removal system. Therefore, the dust removal method is one of the characteristics of the central dust removal system and an important part of the operation of the central dust removal system.
At present, the commonly used ash removal methods are:
1. Gas soot cleaning: The gas soot cleaning is to remove the ash on the filter bag by means of high-pressure gas or external atmospheric back blowing filter bag. Gas soot cleaning includes pulse injection soot cleaning, reverse blowing soot cleaning and reverse suction soot cleaning.
2. Mechanical rapping for ash removal: the top rapping for ash removal and the middle rapping for ash removal (both for filter bags) are used to periodically rappe each row of filter bags in turn with the help of mechanical rapping device to remove the ash deposits on the filter bags.
3. Manual tapping: each filter bag is manually tapped to remove the dust on the filter bag.
The structural types of the central dust removal system are:
1. According to the shape of filter bag, it can be divided into flat bag (trapezoidal and flat) and round bag (cylindrical).
2. According to the air inlet and outlet mode, it can be divided into: lower air inlet and upper air outlet, upper air inlet and lower air outlet, and direct current type (only limited to flat plate bags).
3. It can be divided into external filter bag type dust remover and internal filter bag type dust remover according to bag filtering mode.
The fibers used for filter materials include cotton fiber, wool fiber, synthetic fiber, glass fiber, etc. The filter materials woven with different fibers have different properties. The commonly used filter materials are 208 or 901 polyester flannelette, and the use temperature is generally not more than 120 ℃. The use temperature of glass fiber filter bags treated with silicone resin is generally not more than 250 ℃. Cotton and wool fabrics are generally suitable for non corrosive; Dusty gas with temperature below 80-90 ℃.
