Ventilation and dust removal device for wind power generating set and wind power generating set

Abstract

The invention provides a ventilation dust removal device of a wind power generation set and the wind power generation set. The ventilation dust removal device comprises an air box and dust removal equipment. The air box is divided into an air inlet part and an air outlet part by a separation plate. The dust removal equipment comprises a plurality of dust collection deposition tubes arranged in the air outlet part of the air box, corona electrode wires arranged in the multiple dust collection deposition tubes, a power supply device providing voltage for the dust collection deposition tubes and the corona electrode wires and rapping devices arranged for the dust collection deposition tubes respectively; each dust collection deposition tube is communicated with the air inlet part and provided with a dust collection deposition tube air outlet which is communicated with the air outlet part; the air outlet part is provided with an air box air outlet. According to the ventilation dust removal device of the wind power generation set, ionization occurs to dust, smog and other particles in air by using an electric field generated between the dust collection deposition tubes and the corona electrode wires, so that the extra resistance of the ventilation dust removal device to the air is reduced.

Description

technical field [0001] The invention relates to a ventilation and dust removal device, in particular to a ventilation and dust removal device for a wind power generator set and a wind power generator with the ventilation and dust removal device. Background technique [0002] A wind turbine is a green power generation device that converts wind energy into electrical energy. With the increase of the capacity of a single unit and the increasingly severe high temperature environment of some units, it is necessary to dissipate heat from the wind turbine. [0003] At present, the industry mostly adopts the air-cooling mode for the heat dissipation of the whole machine. The air-cooling mode requires the wind turbines to exchange air with the outside world. However, most of the wind turbines installed on land are located in areas with harsh environments, and the air contains a lot of dust and smoke. These particles will pollute the internal components of the wind turbine, thereby a...

Problems solved by technology

[0003] At present, the industry mostly adopts the air-cooling mode for the heat dissipation of the whole machine. The air-cooling mode requires the wind turbines to exchange air with the outside world. However, most of the wind turbines installed on land are located in areas with harsh environments, and the air contains a lot of dust and smoke. These particles will pollute the internal components of the wind turbine, thus affecting the stability and service life of each component

[0004] For this reason, in the prior art, most of the ventilation systems of wind power generators use air filter cotton devices for dust removal. The situation of blockage will cause the ventilation and heat dissipation system of the unit to collapse and fail to work normally, which will affect the normal operation of the wind turbine and increase the maintenance cost of the wind turbine to a certain extent.

In addition, adding air filter cotton at the entrance of the ventilation system will increase the resistance of the ventilation system, thus requiring a more powerful motor fan, resulting in more power consumption to a certain extent
