Abstract
Description
[Technical field]
[0001] The utility model relates to the technical field of beam supporting ribs, in particular to the technical field of beam supporting ribs used for electric dust collectors. [Background technology]
[0002] Electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate smoke from flue gas emitted by coal-fired or oil-fired boilers, thereby significantly reducing the amount of smoke discharged into the atmosphere. It is an important environmental protection equipment for improving environmental pollution and improving air quality. Since the electrostatic precipitator can adapt to the purification of large-particle, high-powder and high-concentration smoke, it is widely used in flue gas treatment in industrial fields such as power plants, steel plants, cement plants, chemical plants, metallurgical plants, and rubber plants. The electrostatic precipitator has the disadvantages of large metal consumption, large footprint, difficulty in adapting to changes in operating conditions, and the scope of application is limited by the dust resistivity. However, since the electrostatic precipitator has the advantages of high efficiency, large flue gas treatment volume, long life, environmental protection, low energy consumption and maintenance costs, it is currently widely used in domestic and foreign power plants to remove dust from flue gas.
[0003] During the operation of the electrostatic precipitator, the beam and supporting channel steel are often needed to support it in order to ensure stability. However, the operation of connecting the supporting channel steel with the beam is currently cumbersome, and the staff is required to insert the two ends of the supporting channel steel into the beam to ensure stability. Although the connection between the supporting channel steel and the beam can be achieved, it requires the staff to pay a lot of physical strength and energy. Not only is the connection unstable, but the operation is also cumbersome, laborious and difficult to install. It cannot be directly welded to the beam support rib plate, resulting in poor practicality and prone to shaking and instability during long-term use. [Utility Model Content]
[0004] The purpose of the utility model is to solve the problems in the prior art and to propose a beam support rib plate for an electrostatic precipitator, which can directly weld the two ends of the supporting channel steel to the support rib plate flange portion on the beam support rib plate, thereby improving stability, making the operation relatively simple and greatly reducing the difficulty of installation.
[0005] To achieve the above-mentioned purpose, the utility model proposes a beam support rib plate for an electrostatic precipitator, comprising a beam, an upper flange plate, a lower flange plate, a vertical plate, a web plate, a beam support rib plate, a support rib plate flange portion, and a support channel steel. The beam is composed of an upper flange plate, a lower flange plate, a vertical plate, and a web plate. The vertical plate is located between the upper flange plate and the lower flange plate, and the web plate is located in the middle of the vertical plate. The beam support rib plate is installed between the upper flange plate and the lower flange plate and the web plate. One end of the beam support rib plate is protruding outwardly and is provided with a support rib plate flange portion. The beam support rib plate is connected to the support channel steel through the support rib plate flange portion.
[0006] Preferably, one end of the beam supporting rib is connected to a cover plate, and the cover plate is located above the supporting channel steel.
[0007] Preferably, the width and thickness of the upper flange plate and the lower flange plate are the same.
[0008] Preferably, the web is in a concave shape.
[0009] Preferably, the support rib plate flange portion on the beam support rib plate is arranged outside the edge of the upper flange plate, and the width of the support rib plate flange portion is greater than the width of the upper flange plate.
[0010] Preferably, the supporting channel steel is located outside the beam.
[0011] Preferably, both ends of the supporting channel steel are fixed to the flange portion of the supporting rib plate by welding.
[0012] Beneficial effects of the utility model:
[0013] The utility model can improve the reliability and safety of the equipment through the coordinated action of the beam support rib plate, the support rib plate flange and the support channel steel. A support rib plate flange protruding outward is provided at one end of the beam support rib plate. By providing the support rib plate flange, it can be directly welded to the two ends of the support channel steel without inserting the two ends of the support channel steel into the beam, which saves time and effort while being simple to operate. The method of welding the support channel steel and the support rib plate flange can greatly reduce the difficulty of installation, make welding more convenient, and ensure the welding quality of the support channel steel of important load-bearing parts, greatly improve the reliability and safety of the equipment, and increase the service life of the equipment, which is conducive to long-term use, and solves the problem that the support channel steel needs to be inserted into the interior of the beam, which leads to difficult installation and unstable connection.
