Description

One-cylinder-half-multitube composite chimney Technical Field The utility model relates to the technical field of industrial chimneys, in particular to a one-cylinder half-multi-tube composite chimney. Background Conventional multi-tube chimneys are typically chimneys with a plurality of internal chimney tubes disposed within an outer tube, and conventional telescopic chimneys are typically chimneys with an internal chimney tube disposed within an outer tube. The outer cylinder is used as a structural support to resist loads such as wind, earthquake and the like, the inner smoke discharging tube is used as an anti-corrosion smoke discharging structure. Based on the above, the inventor finds that the conventional multi-tube chimney and the inner smoke discharging tube of the conventional sleeve-type chimney are usually arranged from the bottom to the top of the chimney, thus the consumption of the anti-corrosion structure of the inner smoke discharging tube is often increased, the volume of the outer tube is increased, the load of external wind resistance, earthquake and the like is also increased, and the whole manufacturing cost is further increased, so that in view of the above, the conventional structure is researched and improved, and a tube-half multi-tube composite chimney is provided, so that the aim of higher practical value is fulfilled. Disclosure of utility model 1. Technical problem to be solved Aiming at the problems existing in the prior art, the utility model aims to provide a one-tube-half-multi-tube composite chimney, which can arrange a plurality of inner tubes in a lower outer tube and ensure the smoke discharging height by matching with an upper single tube, thereby reducing the anti-corrosion area and the upper single tube structure, greatly reducing the whole structure consumption and the manufacturing cost, and saving the resources and the user investment cost. 2. Technical proposal In order to solve the problems, the utility model adopts the following technical scheme. The semi-multitube composite chimney comprises a lower outer barrel, wherein the inside of the lower outer barrel is fixedly connected with a plurality of lower inner barrels through a bracket, a hole sealing platform is fixedly arranged at the top of the lower outer barrel, an upper single barrel is arranged at the top of the hole sealing platform, a smoke exhaust hole is formed in the position, corresponding to the lower inner barrel, of the hole sealing platform, and the position of a lower opening of the smoke exhaust hole is flexibly connected with the top of the lower inner barrel through an expansion joint. Further, an inner cylinder pulley is arranged on the periphery of the lower inner cylinder, and the periphery of the inner cylinder pulley is movably connected with the inner side wall of the lower outer cylinder. Furthermore, the lower inner cylinder and the upper single cylinder are of carbon steel cylindrical structures, and lining brick rubber systems are arranged on the inner side walls of the lower inner cylinder and the upper single cylinder and the top of the hole sealing platform. Further, a flue gas inlet is arranged at the outer part Zhou Hengxiang of the bottom of the lower inner cylinder, and one end of the flue gas inlet extends to the outer part of the lower outer cylinder.
