I. Introduction
160 bags pulse bag filter is a kind of equipment widely used in industrial dust control, with high efficiency, low energy consumption, easy maintenance and other characteristics. In the process of design and use, the calculation of air volume is a very important part. This article will introduce the air volume calculation method of 160 bags of pulse bag dust collector in detail to help users better understand and use the equipment.
2. Calculation method of air volume of 160 bags of pulse bag dust collector
Determine the nature of the dust to be processed
First of all, it is necessary to understand the nature of the dust to be processed, including particle size, density, viscosity, etc. These properties will have a direct impact on the calculation of air volume. For example, for dust with smaller particles, a larger filtration area and a smaller air velocity are required, so the air volume is reduced accordingly. For less dense dust, a larger air speed is required to maintain the same dust collection efficiency, so the air volume will increase accordingly.
Determine the size and number of filter bags
Once the nature of the dust has been determined, it is necessary to select the appropriate filter bag size and quantity. In general, the size and number of filter bags will affect the filtration area and filtration speed. The larger filter bag size can provide a larger filtration area, allowing for greater air volume to pass through. However, the number of filter bags needs to be determined according to the actual operating conditions and process requirements to ensure the best dust removal effect.
Calculate the filtration area and wind speed
Once the size and number of filter bags have been determined, the filtration area and air speed need to be calculated. The filtration area can be obtained by adding the size of the filter bags, while the air speed can be determined according to the actual operating conditions and process requirements. Generally speaking, a smaller air speed can provide better dust collection, but it will increase the resistance of the filter bag, which will affect the energy consumption and life of the equipment. Therefore, it is necessary to weigh and choose according to the actual situation.
Calculate the air volume
Finally, based on the filtration area and wind speed, the required air volume can be calculated. The air volume can be calculated by the following formula:
q = f × v
where q is the air volume (m h), f is the filtration area (m), and v is the wind speed (m s).
In practical applications, factors such as energy consumption, noise, and pressure loss of the equipment also need to be considered, as well as changes in actual operating conditions and process requirements. Therefore, it is recommended to carry out detailed calculations and tests during design and use to ensure that the equipment can achieve the best dust removal effect and service life.
3. Practical application case analysis
Suppose a factory needs to use a 160-bag pulse baghouse to handle dusty gases, the first thing you need to know is the nature of the dust in the plant. The dust particles at the plant were determined to be 10 m in size and 200 kg m in density. Based on this data, it is possible to select the appropriate filter bag size and quantity. Assuming that a filter bag with a diameter of 200 mm is selected, the number is 160. Based on these parameters, the required filtration area and wind speed can be calculated. Suppose the filtration area is 40m and the wind speed is 1ms. Based on this data, the required air volume can be calculated. Assuming that a fan with Q=10000 MH is selected. Finally, it is necessary to debug and test according to the actual working conditions and process requirements to ensure that the equipment can achieve the best dust removal effect and service life.
Conclusions and recommendations
The air volume calculation of the 160-bag pulse bag filter is one of the most important links. In practical applications, it is necessary to comprehensively consider the nature of dust, the size and quantity of filter bags, the actual working conditions and process requirements and other factors for design and selection, to ensure that the equipment can achieve the best dust removal effect and service life, it is recommended to carry out detailed calculations and tests in the design and use process to avoid unnecessary energy consumption, noise, pressure loss and other problems, at the same time, for different application scenarios, it is necessary to select the appropriate equipment model and technical parameters to achieve the best dust removal effect and create more value for the enterprise!
