Technical Field

[0001] This invention relates to the field of absorption tower technology, specifically to a tray structure, an absorption tower, and a flue gas desulfurization system. Background Technology

[0002] In flue gas desulfurization systems, a desulfurization absorption tower is typically installed. A tray is usually placed between the inlet of the absorption tower and the spray layer. A liquid-holding layer is located above the tray, which efficiently washes away dust and desulfurizes the passing flue gas.

[0003] Horizontal support beams are welded to the inner wall of the absorption tower, and the tray is fixed to the horizontal support beams. The installation height of the tray is usually greater than 500 meters.

[0004] The large total thickness of the aforementioned pallet and horizontal support beam makes the overall structure bulky and complex to install. Summary of the Invention

[0005] In view of this, the present invention provides a pallet structure to solve the problem that the total thickness of the existing pallet and horizontal support beam is large, resulting in a bulky overall structure and complicated installation.

[0006] In a first aspect, the present invention provides a tray structure, comprising:

A cable-stayed pallet is suspended inside the absorption tower, with both ends of the pallet connected to opposite ends of the reinforcing ring. The cable-stayed pallet is made of alloy. Beneficial effects: This application adopts the above technical solution, where the space occupied by the cable-stayed pallet is only the thickness of the pallet itself, and the entire pallet is under tension. It fully utilizes the high tensile strength of the alloy component, ensuring sufficient strength of the cable-stayed pallet and significantly reducing the amount of engineering work and installation costs. Simultaneously, the cable-stayed pallet itself is lightweight, easy to install, and safe and reliable. Furthermore, it fully utilizes the stabilizing characteristics of the annular reinforcing ring to ensure the overall pallet structure is safe and reliable.

[0008] Optionally, it also includes: The ring plate is annular and is arranged around the inner peripheral wall of the absorption tower. The two ends of the suspension tray are connected to the reinforcing ring through the ring plate.

Beneficial effects: This application adopts the above technical solution, fully utilizing the excellent compressive strength of carbon steel to ensure the safety and reliability of the reinforcing ring, thereby guaranteeing the safety and reliability of the pallet structure.

[0014] Secondly, the present invention also provides an absorption tower, comprising: the tray structure described above.

[0015] Optionally, it also includes: A spray layer is located inside the absorption tower and is situated above the suspension tray of the tray structure. The absorption tower is provided with a flue gas inlet and a flue gas outlet. The absorption tower is adapted to introduce flue gas from the flue gas inlet, and then sequentially pass through the suspension tray of the tray structure and the spray layer before being discharged from the flue gas outlet.
