AI Technical Summary

⚠Technical Problem

The existing deflector design is unreasonable, resulting in severe structural vibration and wear, and the cost of modification is high, making it difficult to improve both structural strength and wear resistance at the same time.

⚗Method used

A flue gas duct guide plate is designed, which adopts a surface protrusion and groove structure. The protrusions act as ribs to increase structural strength, and dust accumulation and scouring are used to improve wear resistance. At the same time, the stability is enhanced by reinforcement and wear-resistant devices.

🎯Benefits of technology

It effectively prevents the vibration and wear of the guide vane, reduces material and welding costs, improves structural stability and wear resistance, reduces flue gas system resistance, and optimizes flow field distribution.

Abstract

The application discloses a flue gas duct flow guide plate, which is used in a flue gas duct to change the flow direction of flue gas and comprises a flow guide plate body, wherein a protrusion protruding outward from a surface is formed on one side surface of the flow guide plate body, a groove is formed on the other side surface of the flow guide plate body at a position corresponding to the protrusion, and the two side surfaces of the flow guide plate body are fixedly connected with the flue gas duct. The protrusion on the surface of the flow guide plate body is a "rib" itself, which can guarantee the structural strength of the flow guide plate, save the material cost and welding cost of the reinforcing rib, accommodate part of vibration during operation, improve the stability of the structure, absorb the relative expansion between the inner wall of the flue gas duct and the flow guide plate, prevent the flow guide plate from being pulled or pressed, form dust accumulation on the groove side of the protrusion, and improve the anti-abrasion performance of the flow guide plate by using the principle of directly washing dust with dust.
