Cabin environment control device of offshore wind generating set

Abstract

The invention discloses a cabin environment control device of an offshore wind generating set. The device comprises a cooling system, a dehumidification system, a first sealing structure and a second sealing structure. The cooling system is arranged inside or outside a cabin to adjust the temperature of air in the cabin. The dehumidification system is arranged in the cabin to adjust the humidity of the air in the cabin. The first sealing structure is arranged in a gap between the cabin and a tower drum. The second sealing structure is arranged in a gap between the cabin and a wind wheel. According to the cabin environment control device of the offshore wind generating set, cabin parts of the offshore wind generating set can be prevented from being corroded well.

Description

technical field [0001] The invention relates to the technical field of environment control in a cabin of a wind power generating set, in particular to an environment control device in a cabin of an offshore wind generating set. Background technique [0002] With the increasing pressure on energy and the environment, clean and renewable new energy has received widespread attention in recent years. Among all kinds of green energy, wind energy is one of the renewable energy sources with great prospects and potential. Wind power generation technology is relatively mature, and has the most conditions for large-scale commercial development, and the cost is relatively low. The use of wind energy to generate electricity has attracted increasing attention and has shown a broad space for growth. [0003] Due to the abundance of offshore wind energy resources and the characteristics suitable for large-scale development, in recent years, various wind power companies have shifted their ...

Problems solved by technology

[0007] In the current technology, the filtered fresh air (cold air) outside the cabin is mainly poured into the cabin to form a micro-positive pressure system in the cabin-making the gap between the cabin and the tower, and between the cabin and the wind wheel The air flow direction is from the cabin to the outside, and at the same time, the wind turbine is cooled to control the temperature of the ambient air in the cabin. However, since offshore wind turbines are mostly high-power units, the heat generated is relatively large, and the cabin must be controlled in this way. The temperature of the ambient air in the interior will inevitably have a large flow of fresh air entering the cabin, so it is necessary to have a large flow of salt mist separation or continuous operation of the filter device, but the filter device always has a certain filtration efficiency index limit, which cannot be fully filtered. filter

In this way, the salt content of the ambient air in the cabin will increase day by day due to the cumulative effect, and the replacement frequency of the filter screen will be higher, resulting in lower reliability and higher cost

At the same time, due to the large air flow, the humidity of the ambient air in the cabin is difficult to control. When the humidity of the air in the cabin is above the critical relative humidity for metal corrosion, the metal components in the cabin will be corroded obviously. If the ambient air in the cabin The high concentration of salt spray in the medium will aggravate the corrosion

[0008] Therefore, fundamentally speaking, the current technical solution can solve the problem of high salt content and high temperature of the ambient air in the cabin to a certain extent, but it is difficult to say that a simple and reliable device can simultaneously solve the problem of high salt content in the ambient air in the cabin. The problems of high salt content, high temperature and high humidity, and for offshore wind turbines, only by solving these three problems at the same time can the environment in the engine room meet the requirements and achieve the purpose of anti-corrosion of various parts in the engine room
