Abstract

The invention discloses a large-span circular air-and-flue-gas duct system. The large-span circular air-and-flue-gas duct system comprises a circular air-and-flue-gas duct body, a bottom frame, a first ferrule, a second ferrule and a plurality of stiffening ribs. The first ferrule and the second ferrule are connected on the outer walls of the two ends of the circular air-and-flue-gas duct body in a sleeving mode correspondingly, the stiffening ribs are connected on the outer wall of the circular air-and-flue-gas duct body in a sleeving mode, the first ferrule, the second ferrule and the stiffening ribs are all fixed on the bottom frame and the bottom of the circular air-and-flue-gas duct body is located on the bottom frame, and a plurality of support-hangers are arranged at the bottom of the bottom frame. According to the large-span circular air-and-flue-gas duct system, the investment cost is low, and the occupied area is small.

Description

technical field [0001] The invention belongs to the technical field of flue air ducts, and relates to a large-span circular flue air duct system. Background technique [0002] Boilers in coal-fired power stations and other industrial facilities are often equipped with circular flue gas ducts to achieve the purpose of supplying air and exhausting smoke. The distance between the supports and hangers of conventional circular flue ducts is 6 to 9m. To support the flue ducts, there are flue duct brackets at the supports and hangers, which brings problems such as high civil construction investment cost and large floor space. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a large-span circular flue duct system with low investment cost and small footprint. [0004] In order to achieve the above purpose, the large-span circular flue duct system of the present invention includes...
