Problems solved by technology

[0004] The inventors found that for large floating power generation ships, the amount of power generated is large, more power generation equipment is required, and the connection between devices is more complicated. At present, there is no reasonable way to generate power in the limited space of large floating power generation ships. Plant layout strategy; at the same time, the large floating power generation ship is set on the hull as a whole, and is in a shaking state as a whole due to the influence of water flow. The current power plant design is mostly on land, and there is no specific large-scale Strategies for layout of power plant by real-time shaking of floating power generation ship

Embodiment 1

[0039] The invention takes a gas-steam combined unit on a ship as an example, comprehensively considers factors such as thermal system process flow, equipment function, pipeline flexibility and stability, hull structure characteristics, upper structure stability and other factors, conducts modular design research, and forms a large floating The modular design technology of the main powerhouse of the power generation ship.

[0040] The power generation ship is a gas-steam combined cycle generator set, which adopts the "two-to-one" multi-shaft arrangement scheme. The gas turbine and the waste heat boiler are arranged outdoors, and the steam turbine is arranged indoors.

[0041] The main principles for the division of modular technology modules in the main workshop are as follows:

[0042] (1) The main equipment is arranged on the main deck layer; (2) The auxiliary equipment is arranged below the deck as much as possible; (3) The modules are reasonably partitioned according to th...

Embodiment 2

[0075] like figure 1 As shown, Embodiment 2 of the present invention provides a modular arrangement method for the main powerhouse of a large-scale floating power generation ship, including the following processes:

[0076] Each module (M01~M37) integrates equipment, structures, pipes and cables into independent units, and adopts the design technology of modular design, modular manufacturing on land, and assembly and splicing on board.

[0077] Specifically, the main powerhouse is generally arranged at a low position, the main equipment is arranged on the main deck, and the auxiliary equipment is mainly arranged on the second deck.

[0078] Arrange the two gas turbine generator sets (M01 and M02) in parallel axially, and then connect the gas turbine exhaust diffuser module (M03 and M04), bypass chimney module (M11 and M12) and waste heat boiler module (M13 and M14) in sequence );

[0079] The gas turbine air intake system modules (M05 and M06) are arranged above the gas turb...

Embodiment 3

[0088] Embodiment 3 of the present invention provides a large-scale floating power generation vessel, including the modular system of the main building of the large-scale floating power generation vessel described in Embodiment 1 of the present invention.

Abstract

The invention provides a modularized system for a main workshop of a large floating power generation ship and an arrangement method. Main engine equipment is arranged on a main deck layer, and a plurality of auxiliary engine equipment is arranged on a second deck layer; the main deck layer comprises a gas turbine and electric generator module, an exhaust diffusion section module, an air inlet system module, a front module, a waste heat boiler module, a bypass chimney module, a flash tank platform module, a comprehensive pipe gallery module, a steam turbine and electric generator module, a condenser module, an outer frame module, a circulating water module and a vacuum system module. A steam-water system platform module and an oil system platform module; the second deck layer comprises a gas turbine auxiliary part, a waste heat boiler auxiliary part and a steam turbine auxiliary part. According to the modular power generation ship, the construction mode of land modular manufacturing and module assembling on board is achieved through modular design by combining the structural characteristics of the ship body, the ship body construction period is greatly shortened, the ship body production efficiency is improved, the production quality is guaranteed, and the stability of power generation equipment under real-time shaking of the power generation ship is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of power generation ships, in particular to a modular system and an arrangement method of a main building of a large floating power generation ship. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] Floating power generation vessel is a movable water power station, which can provide power for industrial areas, islands and offshore operation projects in near waters. It is a flexible clean energy supply technology. [0004] The inventor found that for large floating power generation ships, the power generation capacity is large, more power generation equipment is required, and the connection between the devices is more complicated. At present, there is no reasonable way to generate power in the limited space of large floating power generation ships The strategy of plant layout; at the s...
