Embodiment 1

[0031] This embodiment is further elaborated on the basis of the embodiment of the suction air cooler. When the dust removal system receives the dust removal command, the motor that controls the cooling fan will operate at the set time t 0 = Within 600s, operate in the following operation mode to realize the resonance dust removal of the filter device:

[0032] 1) Reverse high speed: at the set high speed value n 1 The first setting time of reverse rotation is t 1 , the high-speed value n 1 In order to meet the heat dissipation requirements of the cooler, the lower limit of the fan speed, t 1 = 300s;

[0033] 2) Reverse low speed: at the set first low speed value n 2 Reverse rotation for the second set duration t 2 , 10s≤t 2 ≤60s, the first low speed value n 2 is the start-up speed value of the fan, t 2 = 30s;

[0034] 3) Forward rotation: with the set forward rotation value n 3 Forward rotation third set duration t 3 , the forward rotation value n 3 is the start-...

Embodiment 2

[0038] This embodiment is further elaborated on the basis of the embodiment of the suction air cooler. When the dust removal system receives the dust removal command, the motor that controls the cooling fan will operate at the set time t 0 = Within 360s, operate in the following operation mode to realize the resonance dust removal of the filter device, see Figure 5 :

[0039] 1) Reverse high speed: at the set high speed value n 1 The first setting time of reverse rotation is t 1 , the high-speed value n 1 In order to meet the heat dissipation requirements of the cooler, the lower limit of the fan speed, t 1 = 60s;

[0040] 2) Reverse low speed: at the set first low speed value n 2 Reverse rotation for the second set duration t 2 , the first low speed value n 2 is the start-up speed value of the fan, t 2 = 10s;

[0041] 3) Forward rotation: with the set forward rotation value n 3 Forward rotation third set duration t 3 , the forward rotation value n 3 In order to ...

Embodiment 3

[0045] This embodiment is further elaborated on the basis of the embodiment of the suction air cooler. When the dust removal system receives the dust removal command, the motor that controls the cooling fan will operate at the set time t 0 = Within 960s, operate in the following operation mode to realize the resonance dust removal of the filter device:

[0046] 1) Reverse high speed: at the set high speed value n 1 The first setting time of reverse rotation is t 1 , the high-speed value n 1 In order to meet the heat dissipation requirements of the cooler, the lower limit of the fan speed, t 1 = 600s;

[0047] 2) Reverse low speed: at the set first low speed value n 2 Reverse rotation for the second set duration t 2 , the first low speed value n 2 is the start-up speed value of the fan, t 2 = 60s;

[0048] 3) Forward rotation: with the set forward rotation value n 3 Forward rotation third set duration t 3 , the forward rotation value n 3 is the start-up speed value ...

Abstract

The invention relates to a suction type air cooler and a dust removal method and system of a filter device and belongs to the technical field of wind power generation. The suction type air cooler comprises a shell, a cooling fan arranged on one side of the shell and a motor driving the cooling fan to rotate. The filter device is arranged at an air inlet of the shell, cooler fins are arranged between the filter device and the cooling fan, and the average perpendicular distance of cooler fin holes close to the side of the filter device and frames of the filter device is equal to or smaller than three times the hydraulic diameter of each fin hole; and the motor driving the cooling fan to rotate is connected with the dust removal system of the filter device, and when the dust removal system receives a dust removal instruction, the motor is controlled to enable the filter device to remove dust in a syntonic mode. By adoption of the scheme of the suction type air cooler and the dust removal method and system of the filter device, impurities on the filter device at the air inlet of the air cooler can be effectively cleared away, blocking of the filter device is prevented, the maintaining interval of the air cooler is lengthened, the maintaining duration of the cooler is shortened, and the benefits are created.

Description

technical field [0001] The invention relates to a dust removal method and system of a suction air cooler and a filtering device, and belongs to the technical field of wind power generation. Background technique [0002] At present, wind turbines working in the field require a service life of 20 years, and the air coolers used in them are often blocked by catkins, dust, debris or sandstorms in the field, which affects the cooling effect and requires irregular maintenance. Because the fin through holes of the air cooler are relatively deep and small, after a long period of wind, sand, catkins and other sundries block the fin through holes, it is difficult to clear the blockage, which in turn affects the normal operation of the entire air cooler. [0003] In the prior art, the Chinese patent document "Cooler Automatic Dust Removal Device and Dust Removal Method for Strong Oil Circulation Power Transformer" with the publication number CN103521483 discloses a cooler automatic dus...
