An offshore platform jet condensing device

Abstract

The invention relates to the field of ship power, and discloses a jet-type condensing device for an offshore platform, comprising: a condensing chamber; a cooling water inlet pipeline and several water chambers are installed in the condensing chamber, and each water chamber is connected to the cooling water inlet pipeline Communication; each water chamber includes: a baffle structure and multiple cooling units separated by the baffle structure; the baffle structure is provided with a number of communication holes, and each cooling unit is sequentially connected through corresponding communication holes. The offshore platform jet condensing device provided by the present invention sets several water chambers in the condensation chamber and divides the water chambers into different areas through the partition structure, and uses the communication holes provided on the partition structure to make the adjacent cooling units Through the sequential communication of the corresponding communication holes, the pressure of each cooling unit in the water chamber can be kept basically the same, so that the uniformity of the liquid film produced by each cooling unit can be maintained on the basis of improving the adaptability of the water chamber to the marine environment, and the fluctuation of condensation efficiency can be reduced. Maintain the stable operation of the entire power system.

Description

technical field [0001] The invention relates to the field of ship power, in particular to a jet-type condensing device for an ocean platform. Background technique [0002] The power system is an important part of marine platforms such as ships. It directly determines the speed, endurance, mobility, daily operation and energy and electricity required for personnel life of the offshore platform. The steam Rankine cycle is one of the more common power systems at present. First, the condenser is the main equipment of the steam power system, which directly determines the efficiency, safety and flexibility of the power system. Partitioning wall condensers, shell-and-tube heat exchangers, and plate heat exchangers are the main forms of condensers in current ship power systems. However, shell-and-tube heat exchangers have limited heat transfer per unit volume, large volume and weight, and occupy a large amount of ocean space. The space on the platform is precious, the high pressure...

Problems solved by technology

However, it should be noted that the current jet condenser is mainly designed for processing on land or fixed platforms, and does not consider the influence of swings caused by ocean currents, wind waves, etc. in the ocean environment, which may cause large fluctuations in condensation efficiency and affect the stable operation of the power system.
