What are the basic requirements for selecting an industrial dust collector?
l. Selecting the type of processing gas according to the amount of processing gas is the decisive factor in determining the size and type of industrial dust collectors . For the amount of air, be sure to choose a duster that can handle the amount of air. It is often uneconomical to use; for smaller gas volumes, it is most economical to compare which type of dust collector to use, and it is the easiest to meet the environmental requirements of dust source control and dust emission. After the dust collector enters the actual operation. Affected by operating and environmental conditions are sometimes difficult to predict. Therefore, when deciding the capacity of the equipment, it is necessary to ensure a certain margin or reserve some space that may increase the equipment.
2. Selection of dust dispersion according to the dispersion and density of dust has a great impact on the performance of industrial dust collectors , and the dispersion of dust is the same, due to different operating conditions. Therefore, when choosing the type of dust collector, the first thing is to accurately grasp the dispersion degree of the dust. For example, when the particle size is more than 10 μm, a cyclone dust collector can be selected. In the case of particle diameters of several microns or less, electrostatic precipitators and bag precipitators should be selected. For specific selection, you can make a preliminary selection based on the degree of dispersion and other requirements, and refer to the common types of dust collectors and performance tables. Then follow other conditions and The type and performance of the dust collector introduced are determined.
Dust density also has a great impact on the dust removal performance of industrial dust collectors. The most obvious manifestations of this effect are gravity, inertial and centrifugal precipitators. A common feature of all dust collectors is that the smaller the bulk density, the more difficult the separation and capture of dust particles, and the more serious the second fly of dust, so special measures should be taken in operation and equipment structure.
3. Dust removal skeleton and dust filter bag factor The application of dust removal skeleton in bag dust collector is also very extensive. The dust removal points involved in dust removal on the ground of the dust removal framework include the smoke guide holes on the top of the furnace, the side of the coal loader, the door of the coke oven, the guide grille, and the top of the quenching car. After the dust is collected through the dust suction hood and pipes, it passes through the telescopic sleeve that is connected with the smoke guide car, the coal loading coke pushing car and the coke blocking car. The dust collector is purified, and the cleaned gas is discharged into the atmosphere through a fan and a chimney. Overcome the cheating of compressed air pulse cleaning. The anti-blowing effect has a large distance, and a long filter bag can be used to make full use of space and occupy a small area. The trapezoidal flat bag is arranged in the cylinder, and the structure is simple and compact, which improves the service life of the filter bag.
