With the continuous strengthening of environmental awareness, dust removal equipment has been widely used in industrial production. Among them, the stainless steel bag filter has been widely welcomed as an efficient and environmentally friendly dust removal equipment. This article will introduce and analyze the structural design of stainless steel bag filter in detail.
1. Overview. Stainless steel bag filter is an efficient and environmentally friendly dust removal equipment, which has the advantages of simple structure, convenient maintenance, large air volume and high dust removal efficiency. Its working principle is to use a filter cloth to filter the dust in the gas to achieve gas purification. In order to ensure the dust removal effect and the stability of the equipment, the structural design of the stainless steel bag filter is particularly important.
2. Structural design.
1.Cabinet design.
The box is the main structure of the stainless steel bag filter, and its design should consider factors such as strength, stiffness, anti-corrosion, and sealing. The commonly used materials are carbon steel and stainless steel, and the appropriate material and thickness can be selected according to actual needs. At the same time, the design of the box should fully consider the convenience of installation and maintenance, and reasonably set up manholes, access doors, etc.
2.Filter bag design.
The filter bag is the core component of the dust collector, and its material, size, shape and other factors have an important impact on the dust removal effect. Commonly used filter bag materials are polyester, polypropylene, etc., and the appropriate materials and specifications are selected according to the actual working conditions. The size and shape of the filter bag should be designed according to the size and shape of the box to ensure the stability and sealing after installation. At the same time, the opening design of the filter bag should be convenient for cleaning and replacement.
3.Injection system design.
The injection system is an important part of the stainless steel bag filter, and its design should consider the injection pressure, injection time, nozzle diameter and other factors. The function of the injection system is to spray compressed air into the inside of the filter bag through the nozzle to blow off the dust attached to the surface of the filter bag. The diameter and number of nozzles should be selected according to the size and number of filter bags, and the control of injection pressure and injection time should be considered to ensure the cleaning effect and the stability of the equipment.
4.Design of ash discharge system.
The function of the ash discharge system is to discharge the collected dust out of the dust collector, and the commonly used ash discharge methods include screw conveyor and scraper conveyor. The design of the ash discharge system should consider factors such as ash discharge capacity, conveying distance, conveying angle, etc., and at the same time ensure that the dust does not fly during the conveying process and the emission meets the environmental protection requirements. The position and shape of the ash discharge port should be designed according to the structure of the box and the size of the conveying equipment to ensure the convenience of installation and maintenance.
5.Design of the control system.
The control system is a key part of the stainless steel bag filter, and its design should consider factors such as the degree of automation, safety and reliability. Commonly used control systems include PLC control cabinets, sensors, actuators and other equipment. The design of the control system should ensure the stable operation of the equipment and the effectiveness of the safety protection function, and at the same time realize automatic control and remote monitoring, so as to improve the operation efficiency and management level of the equipment. The interface of the control system should be user-friendly and easy to use, which is easy to use and manage for operation and maintenance personnel.
III. Conclusion. The structural design of the stainless steel bag filter involves many aspects, including box design, filter bag design, injection system design, ash discharge system design and control system design. In order to achieve efficient and stable dust removal effect, various factors should be fully considered in the structural design, materials and equipment should be reasonably selected, and the design scheme should be optimized. At the same time, the structural design should focus on practicability and economy, reduce the manufacturing cost and use cost of the equipment as much as possible, and improve the market competitiveness of the equipment.
