Rectangular flue gas duct system without internal supporting rods

Abstract

The invention discloses a rectangular flue gas duct system without internal supporting rods. The system comprises a flue gas duct body and a plurality of trusses in annular structures, the trusses in annular structures axially and sequentially sleeves the outer wall of the flue gas duct body, and a plurality of supporting hangers are arranged at bottoms of the trusses in annular structures. A plurality of reinforcing ribs are arranged between every two adjacent trusses in annular structures and uniformly and axially distributed on the outer wall of the flue gas duct body, and each reinforcing rib is connected with all of the trusses in annular structures. The system is low in resistance, uniform in flow field of the flue gas duct, low in investment cost and small in floor space, and the problem of proneness to abrasion, dust accumulation and shedding of the internal supporting rods is avoided.

Description

technical field [0001] The invention belongs to the technical field of smoke ducts, and relates to a rectangular smoke duct system without inner support rods. Background technique [0002] The distance between supports and hangers of a conventional rectangular flue duct is 6-9m. In order to support the flue duct, the supports and hangers are equipped with flue duct supports, which brings about problems such as high civil construction investment costs and large floor space. [0003] Conventional rectangular flue gas ducts are equipped with inner struts, which lead to problems such as large resistance of the flue gas duct system, uneven flow field of the flue gas duct, and easy wear and tear of the inner struts. For the anti-corrosion flue, there are also problems such as the difficulty of anti-corrosion construction at the inner strut, and the easy peeling of the anti-corrosion at the inner strut, and once the anti-corrosion layer is damaged, it will cause huge damage to the ...

AI Technical Summary

Problems solved by technology

[0002] The distance between supports and hangers of a conventional rectangular flue duct is 6-9m. In order to support the flue duct, supports and hangers are provided with supports for the flue duct, which brings problems such as high civil construction investment cost and large floor space.

[0003] Conventional rectangular flue gas ducts are equipped with inner struts, which bring problems such as large resistance of the flue gas duct system, uneven flow field of the flue gas duct, and easy wear and tear of the inner struts, etc.

For the anti-corrosion flue, there are still problems such as the difficulty of anti-corrosion construction at the inner strut, and the easy peeling of the anti-corrosion at the inner strut, and once the anti-corrosion layer is damaged, it will cause huge damage to the overall safety of the flue structure
