Description
Technical field
The present invention relates to a kind of blowers, more specifically, it relates to which a kind of vapour, electric hybrid drive blower fan structure.
Background technique
China's thermal power generation accounts for the 70% of national generating capacity, and Industrial Stoves are also widely used in glass, metal, building materials etc.
Various industries.Blower as subsidiary engine be applied to boiler, Industrial Stoves, the ventilation of drying oven and air inducing, general large-sized station boiler,
Ventilation blower, the air-introduced machine of Industrial Stoves, which generally use, to be driven by electricity, and blower becomes the biggish subsidiary engine of power consumption, in order to reduce power consumption
Amount, have steam rich under conditions of, using Steam Turbine Driven, the low power consumption rate of senior general.Steam-operating blower is in practical applications
It is with good economic efficiency, advantage can be brought for enterprise, but steam-operating blower still have in practical applications it is insufficient
Place: 1, starting vapour original problem, and in the case where unit starting initial stage is without adjacent machine steam supply, steam-operating blower does not have starting band
Loading condiction needs to be arranged electric fan for boiler and provides ventilation and air inducing, causes equipment investment big, and electric fan utilization rate is low
The problem of；2, underload is poor for applicability, and when boiler load is down to certain certain value, the steam inlet condition reduction of steam-driven induced draft fan cannot
Meet to operate normally phenomena such as requiring, leading to blower output drop or unstable power output, influences system and normally produce；3, by vapour source
Influence it is big, steam supply cannot as electric power continuous-stable, when steam supply unit when something goes wrong, not can guarantee steam-operating blower institute
The flow and pressure for needing steam, cause boiler, kiln not to produce normally, even stop production；4, control system, breakdown maintenance compared with
Motor complex, maintenance cycle are long, and when control system and steam turbine failure, maintenance requirement is higher than motor, needs
Very professional personnel and producer are handled, and spare part is selectively single and the processing time is longer, seriously affect running efficiency of system.
Therefore steam-operating blower technically, it is still necessary to gone from multiple angles it is perfect, make steam-operating blower in each industry application become more
Addition is ripe, more advantageous.
Summary of the invention
It is complicated that the present invention overcomes blower driving structures, using single gas source driving or motor driven many times
It is not able to satisfy normal operation to require, influences the deficiency normally produced, provide a kind of vapour, electric hybrid driving blower fan structure, wind
