Ventilating and filtering heat exchange device and method of offshore wind driven generator set

Abstract

The invention discloses a ventilating and filtering heat exchange device and method of an offshore wind driven generator set, wherein the device is arranged in a cabin cover of the wind driven generator set, and comprises a heat exchanger and a filtering box body; the heat exchanger comprises a draught fan and a heat radiating structure; the heat radiating structure is connected with a heating device through a pump set so as to form enclosed-type circulation of a heat exchange medium; the inlet of the filtering box body is provided with a steam water separator; an air filtering core body is arranged behind the steam water separator; the filtering box body is arranged at the air cooling inlet side of the heat radiating structure of the heat exchanger; the draught fan is arranged at the other side of the heat radiating structure; and the cabin cover is provided with an open pore. According to the invention, air of offshore environment is introduced to the filtering box body through the draught fan, steam and water are separated, the air is filtered and purified, air after purification enters the heat exchanger so as to cool down the heat exchange medium, the air after heat exchange enters the cabin and is mixed with the original environment, the air is discharged from the open pore on the cabin cover, and the positive pressure effect in the cabin is ensured; and the device can simplify the structure, can enable the space to be compact, and can improve the integral environment quality in the cabin.

Description

technical field [0001] The invention relates to the field of offshore wind power generators, in particular to a ventilating, filtering, and heat-exchanging device and method for offshore wind power generators. Background technique [0002] A wind turbine is an equipment that uses wind energy to generate electricity. During the process of wind power generation, the heat generated by electronic components, mechanical friction, electromagnetic effects, etc. will affect the normal operation of the unit, so it is necessary to cool and dissipate some equipment; seawater in the ocean The continuous violent disturbance day and night causes the waves to collide with each other and the waves to slap the coastal reefs, producing a large amount of foam. The biological and chemical processes on the sea floor generate gas. Under the action of sea breeze and air current, they rise into the air, undergo complex evolution processes such as cracking, evaporation, and mixing, and become a salt...

Problems solved by technology

[0003] The existing structure requires separate induced draft fans for the two systems, and a separate cooling compartment for the heat exchanger. As the heat exchanger is used for a long time, it is easy to accumulate salt mist and other damages in the gaps of the heat exchanger. Particulate matter, which reduces the heat dissipation performance of the heat exchanger
