In the utility model further preferred embodiment, first pressure sensing is provided on the dust removal filter 12
Device 8 is provided with second pressure sensor 14 on cyclone 15.
As system works, the light dust for being attached to 11 surface of filter core is more and more, when light dust is attached
When more, just influences whether the dust suction work of system, need to carry out deashing processing at this time, the utility model passes through 5 kinds of modes
It is filtered the deashing processing of filter core 11, it is specific as follows：
1, pressure difference controls deashing：When system worked well, the airflow smooth of internal system, first pressure sensor 8 and
Pressure difference between two pressure sensors 14 is maintained at a relatively low range, such as less than 1KPa, when work a period of time after, filtering
The surface of filter core 11 is attached with a large amount of dust, and air-flow enters hindered when 11 inside of filter core so that and pressure difference increases,
When pressure difference increases above setting numerical value, such as 10KPa, electric-control system 1 carries out deashing processing at this time, and processing step is as follows：Instead
Blowpipe road connect through electromagnetic impulse valve with compressed air babinet, control compressed air by blowback pipeline at a time interval
Mode enters inside filter core 11, and 11 internal pressure of filter core increases rapidly, and a compressed air part is sucked by pipeline
Wind turbine 5, a part enter dust removal filter 12 by filter core 11, and compressed air carries out blowback to filter core 11 so that
The dust being attached on filter core 11 is fallen in the hopper of dust removal filter 12；Simultaneity factor is constantly in working condition,
When pressure difference is restored within the numerical value of setting, then stops deashing, handled by clear dirt, extend the service life of system, improves
The use quality of system.
2, current control deashing：When system worked well, the running current size of the automatic detection blower fan of system 5 works as wind turbine
Cause electric current excessive since windage is excessive, carries out deashing.
3, FREQUENCY CONTROL deashing：After system boot, work as system worked well, 5 working frequency of wind turbine should be counterpart terminal
Opening number correspond to and stablize in a certain range, if super go beyond the scope can carry out deashing, until the fortune of wind turbine 5
Line frequency is restored within the scope of this.
4, timing controlled deashing：No matter 11 deashing of filter core is in any state, and 1 timing of electric-control system is to filter core
11 carry out deashing.
5, workflow deashing：Automatically controlled control system carries out a deashing operation before each booting or shutdown.
When carrying out blowback cleaning filter core 11, compressed air is heated system by compressed air heater box, is avoided
When the compressed air of winter blowback is contacted since temperature is relatively low with dust, dust is condensate on filter core 11, ash-removal effect
More preferably.
In the utility model further preferred embodiment, a mechanical safety valve 7 is also associated on the dedusting cavity
That is pressure safety valve (being principle by pressure-control valve core, the prior art repeats no more), the mechanical safety valve 7 is in wind turbine 5
When suction port pressure is less than threshold value, automatically opens, prevent 5 superpressure of wind turbine and overlond running.It is set to wind turbine 5 and filtering filter
Between core 11, it can play the role of protecting wind turbine 5.For example, working as system instrument failure, it is connected to wind turbine 5 and dust removal filter
Pipeline between 12 is in blocked state again when, wind turbine 5 may be in the state of superpressure operation, the i.e. suction port of wind turbine 5
It is too low to locate pressure values, at this point, mechanical safety valve 7 will automatically turn on, protection wind turbine 5 will not superpressure and overlond running.
