The cooling system of offshore equipment and the ships and offshore platforms using the cooling system

Abstract

The invention provides a cooling system for offshore equipment and ships and ocean platforms using the cooling system. The cooling system includes a low-temperature cooling subsystem, a high-temperature cooling subsystem, a temperature control subsystem and an adjustment subsystem; the low-temperature cooling subsystem is used for Cooling low-temperature users, with a first inlet and a first outlet; high-temperature cooling subsystem for cooling high-temperature users, with a second inlet and a second outlet, the temperature control subsystem is used to cool the cooling water to the first predetermined temperature, There is a third inlet and a third outlet; the third outlet is connected to the first inlet through a low-temperature pipeline, the first outlet is connected to the second inlet through a medium-temperature pipeline, and the second outlet is connected to the third inlet through a high-temperature pipeline; adjustment subsystem settings Between the first outlet and the third inlet, the amount of water entering the second inlet is adjusted so that the water temperature at the second outlet is the second predetermined temperature. The invention can reduce the operating cost of the system, facilitate high-temperature users to operate in a matching temperature environment, and improve the performance of ships and ocean platforms.

Description

Technical field [0001] The present invention relates to the field of ships and ocean engineering, in particular to a cooling system for offshore equipment and ships and ocean platforms using the cooling system. The cooling system is especially suitable for ships or ocean platforms with high-power main engines or generators. Background technique [0002] With the depletion of land resources, the outward development of the economy, and the efficient use of resources, countries are paying more and more attention to the development of the ocean, and the demand for various large-scale marine engineering ships is increasing. With the increase in the power of marine engineering ships, the requirements of the equipment operating environment are getting higher and higher, the heat generation of power equipment such as the main engine will increase, and the demand for cooling water will also increase. [0003] Refer to figure 1 In the existing marine cooling system, due to the large differen...

Problems solved by technology

Using this form of cooling, to ensure that the cooling water of the high-temperature equipment meets the heat dissipation requirements, the amount of cooling water flowing through the high-temperature equipment must be large enough. The amount of water in the entire system is the sum of the cooling water flowing through the high-temperature water equipment and the low-temperature water equipment. The cooling water will affect the displacement and quantity of the transfer pump used, which will affect the cost of the construction project, and increase the difficulty of equipment layout, increase the weight of the ship or offshore platform, reduce the load capacity, and affect the performance

In this system, the water temperature entering the low-temperature water and high-temperature water is the same, and the water temperature cannot meet the temperature requirements required by the high-temperature equipment, and the high-temperature equipment will not be able to operate in the best state. Take the high-temperature water part of the main engine as an example. Once it flows through the high-temperature equipment—the water temperature of the cylinder liner is too low to meet the heat dissipation requirements (usually the water temperature requirement of the water inlet of the cylinder liner is preferably 50°C-60°C), which will affect the combustion efficiency of the main engine. When the temperature is lower than the set value, a low temperature alarm will be issued. If the temperature continues to drop, the host will shut down

The high-temperature water part of the main engine is a high-efficiency main engine when the working water temperature of the cylinder liner is around 100 degrees Celsius. If the design temperature is around 80 degrees Celsius, the main engine is not an excellent main engine and needs to be improved.
