Buffer structure of ship tail gas treatment device

Abstract

The invention discloses a buffer structure of a ship tail gas treatment device, and belongs to the technical field of ship engineering. The buffer structure comprises a chimney cabin and the ship tailgas treatment device arranged in the chimney cabin, wherein two groups of fixing sleeve plates are respectively fixed to the two ends of the outer wall of the ship tail gas treatment device; first buffer parts are uniformly arranged on the outer wall of each fixing sleeve plate, one end of each first buffer part is fixed to the outer wall of the corresponding fixing sleeve plate, and the other end of each first buffer part is connected with the inner walls of the two ends of the chimney cabin through a first adjusting nut; and a buffer cushion block is further fixed to the middle of the outerwall of the ship tail gas treatment device and a second buffer part is arranged between the buffer cushion block and the inner wall of the chimney cabin. The rigid impact between the ship tail gas treatment device and the chimney cabin is reduced, the safety performance of the ship tail gas treatment device in the chimney cabin is effectively protected, the noise is lowered, the buffer effect ofthe ship tail gas treatment device is greatly improved, the service life of the ship tail gas treatment device is prolonged, and the high stability is achieved.

Description

technical field [0001] The invention relates to the technical field of ship engineering, in particular to a buffer structure of a ship tail gas treatment device. Background technique [0002] At present, with the development of the international shipping industry and ocean-going shipping, exhaust emissions from ship engines have become the main source of pollution in coastal areas, especially ports. In order to reduce the severity of the pollution caused by the exhaust gas to the atmospheric environment, the ship exhaust gas treatment device is arranged and installed inside the ship chimney along with the ship exhaust system. [0003] At present, the safety performance of the common ship exhaust treatment device is low, and in terms of installation, the ship exhaust treatment device is directly fixed on the chimney structure wall through a rigid support structure, and its front and rear ends are connected to the exhaust pipe of the diesel engine. However, such installation ...

Problems solved by technology

[0003] At present, the safety performance of the common ship exhaust treatment device is low, and in terms of installation, the ship exhaust treatment device is directly fixed on the chimney structure wall through a rigid support structure, and its front and rear ends are connected with the exhaust pipe of the diesel engine

However, such installation will cause the vibration of the bulkhead of the chimney structure to be directly transmitted to the ship's exhaust gas treatment device, which will affect the service life and treatment effect of the ship's tail gas treatment device, and make the ship's tail gas treatment device prone to fatigue damage under long-term operation, which cannot meet the requirements of use. need
