How to better design pulse bag filter

The pulse bag filter is a common industrial dust removal equipment. When designing the pulse bag filter, the following steps can be followed:

Determine the dust removal requirements: first of all, it is necessary to clarify the specific requirements of industrial dust removal, including the gas flow rate, dust concentration, dust characteristics, etc. These parameters will determine design parameters such as collector size, filter bag material and layout.

Select filter bag material and specification: According to the dust characteristics and working environment, select the appropriate filter bag material and specification. Common filter bag materials include polyester fiber, glass fiber, polypropylene, etc. The specifications of the filter bag include length, diameter and pore size.

Design filter bag layout: It is a common design method to adopt a vertical bag layout, and the filter bags are hung vertically inside the dust collector. According to the gas flow direction and dust removal requirements, determine the spacing and arrangement of filter bags to ensure uniform dust distribution and effective filtration.

Design of pulse injection system: The pulse injection system is used to clean the dust on the surface of the filter bag. During the design, it is necessary to determine the position and quantity of the injection pipe, as well as parameters such as injection pressure and injection cycle. The design of the pulse injection system should take into account the layout and size of the filter bags to ensure that each filter bag can be fully cleaned.

Airflow design: design airflow channels and fan systems according to dust removal requirements and filter bag layout. Factors such as airflow velocity, airflow distribution, and airflow resistance are considered to ensure that dust can be effectively settled and collected while reducing energy consumption and pressure loss.

Structural design: Design the structure of the dust collector, including the shell structure, inlet and outlet pipes, ash hopper and ash cleaning device. The structural design should consider the stability, airtightness and ease of maintenance of the equipment to facilitate operation and maintenance.

Perform system calculation and simulation: perform system calculation and simulation based on design parameters to verify the rationality and performance of the design. Air flow analysis, pressure loss calculation, etc. can be performed using calculation software or simulation tools.

Formulate the construction plan: formulate a detailed construction plan based on the design results, including material procurement, equipment installation, pipeline connection, etc
