Pulse bag filter is a kind of dust removal equipment widely used in industrial fields, and the selection of its model parameters is very important for the performance and use effect of the equipment. This article will introduce the model parameters of the pulse bag filter in detail to help readers better understand and choose the dust removal equipment that is suitable for them.
First, the basic principle of pulse bag filter.
Pulse bag filter is a kind of dry dust removal equipment, its main working principle is to filter the dust-containing gas through the filter bag, the dust particles are trapped on the surface of the filter bag, and the clean gas enters the clean air chamber through the filter bag, and finally discharges to the atmosphere. When the dust accumulated on the surface of the filter bag reaches a certain thickness, the dust on the filter bag is removed through the action of the pulse jet cleaning mechanism to ensure the normal operation of the dust collector.
Second, the model parameters of the pulse bag filter.
1.Treatment air volume (q): The treatment air volume refers to the volume of dusty gas that the dust collector can handle in a unit time, usually in cubic meters of hours (m h). The size of the treated air volume should be determined according to the actual production of dust generation, dust concentration and emission standards and other factors.
2.Filtration wind speed (V): Filtration wind speed refers to the speed at which dusty gases pass through the filter bag, usually measured in meters and minutes (m min). The selection of filter wind speed should comprehensively consider the dust nature, filter bag material, ash cleaning method and other factors to ensure the dust removal efficiency of the dust collector and the service life of the filter bag.
3.Filter bag material: The filter bag is the core component of the pulse bag filter, and the choice of material directly affects the performance and service life of the dust collector. Common filter bag materials are polyester fiber, glass fiber, PTFE, etc. When selecting the filter bag material, the corrosiveness, temperature, humidity and other factors of the dust should be fully considered.
4.Pulse injection pressure (P): Pulse injection pressure refers to the pressure generated by the pulse injection mechanism during the ash cleaning process, usually in Pascal (Pa). The size of the pulse injection pressure should be determined according to the material and thickness of the filter bag and the nature of the dust, so as to ensure the ash cleaning effect and the service life of the filter bag.
5.Pulse injection frequency (f): Pulse injection frequency refers to the number of times that the pulse injection mechanism carries out ash cleaning in a unit of time, usually in the unit of minutes. The selection of pulse injection frequency should comprehensively consider the adhesion of dust, the air permeability of the filter bag and the ash cleaning effect, so as to ensure the stable operation and dust removal efficiency of the dust collector.
3. Precautions for the selection of pulse bag filter.
1.When choosing a pulse bag filter, you should fully understand the dust characteristics in the production process, including the particle size, concentration, humidity, abrasiveness, etc. of the dust, so as to select the appropriate model parameters.
2.According to the actual production demand, determine the size of the treatment air volume to avoid too large or too small selection resulting in poor dust removal effect or waste of resources.
3.When selecting the material of the filter bag, the corrosiveness and temperature of the dust should be fully considered to ensure the service life and dust removal effect of the filter bag.
4.According to the material and thickness of the filter bag, as well as the nature of the dust, the pulse injection pressure and frequency are reasonably determined to ensure the ash cleaning effect and the service life of the filter bag.
5.In the process of use, the pulse bag filter should be regularly inspected and maintained, and the dust on the filter bag should be cleaned up in time to ensure the normal operation and dust removal effect of the dust collector.
In short, the model parameter selection of the pulse bag filter is very important for the performance and use of the equipment. In the process of selection, you should fully understand the dust characteristics in the production process, and comprehensively consider factors such as treatment air volume, filtration wind speed, filter bag material, pulse injection pressure and frequency, etc., in order to choose the dust removal equipment suitable for you. At the same time, regular inspection and maintenance should be carried out during use to ensure the normal operation and dust removal effect of the dust collector.
