Description
Technical field
The utility model relates to a kind of improvement of utility boiler blower fan structure.
Background technique
At present, the induced draught fan of station boiler all uses electric drive motor usually, thus Driving Fan running, be the energy of gas by the mechanical energy of blower fan, reach the effect of supplied flue gases.This method of operation, consume electric energy very large, energy saving is poor, there is the problem of waste resource.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of utility boiler energy-saving fan of energy-conserving and environment-protective.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme.The utility model comprises induced draught fan, it is characterized in that: one end of the main shaft of induced draught fan drives the rotating shaft of dual-purpose motor to be connected with generating; The other end of the main shaft of induced draught fan is connected with the live axle of back pressure turbine.
As a kind of preferred version of the present utility model, between the live axle of described back pressure turbine and induced draught fan, be provided with speed reducer and clutch.
The utility model additionally provides a kind of utility boiler system of energy-conserving and environment-protective, comprises boiler body, and boiler body is connected with induced draught fan; Boiler body is provided with steam (vapor) outlet, it is characterized in that: one end of the main shaft of induced draught fan drives the rotating shaft of dual-purpose motor to be connected with generating; The other end of the main shaft of induced draught fan is connected with the live axle of back pressure turbine; The steam (vapor) outlet of described boiler body is connected with back pressure turbine.
Speed reducer and clutch is provided with between the live axle of described back pressure turbine and induced draught fan.
The beneficial effects of the utility model: the utility model is simple, compact and reasonable for structure; Save energy, reduce cost; Stable working state; The utilization ratio of waste heat is high, little to the pollution of environment; Cost of investment is few, and working service amount is little; Reduce energy loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model utility boiler energy-saving fan.
Fig. 2 is the structural representation of the utility boiler system of the utility model energy-conserving and environment-protective.
1 be back pressure turbine, 2 be live axle in accompanying drawing, 3 be speed reducer, 4 be clutch, 5 be main shaft, 6 be induced draught fan, 7 be rotating shaft, 8 drive dual-purpose motor, 9 to be boiler body, 10 for steam (vapor) outlet for generating.
Embodiment
The utility model comprises induced draught fan 6, it is characterized in that: one end of the main shaft 5 of induced draught fan 6 drives the rotating shaft 7 of dual-purpose motor 8 to be connected with generating; The other end of the main shaft 5 of induced draught fan 6 is connected with the live axle 2 of back pressure turbine 1.
As a kind of preferred version of the present utility model, between the live axle 2 of described back pressure turbine 1 and induced draught fan 6, be provided with speed reducer 3 and clutch 4.
The utility model additionally provides a kind of utility boiler system of energy-conserving and environment-protective, comprises boiler body 9, and boiler body 9 is connected with induced draught fan 6; Boiler body 9 is provided with steam (vapor) outlet 10, it is characterized in that: one end of the main shaft 5 of induced draught fan 6 drives the rotating shaft 7 of dual-purpose motor 8 to be connected with generating; The other end of the main shaft 5 of induced draught fan 6 is connected with the live axle 2 of back pressure turbine 1; The steam (vapor) outlet 10 of described boiler body 9 is connected with back pressure turbine 1.
Speed reducer 3 and clutch 4 is provided with between the live axle 2 of described back pressure turbine 1 and induced draught fan 6.
Described generating drives dual-purpose motor to be can from the existing equipment purchased on the market.
Energy-conserving and environment-protective utility boiler system of the present utility model, during use, first start generating and drive dual-purpose motor 8, generating drives dual-purpose motor to drive induced draught fan 6 to rotate, and induced draught fan 6 is boiler body 9 air draft; Boiler body 9 starts.When boiler body 9 reaches rated power, the water in boiler body 9 is boiled; Water vapour is exported by the steam (vapor) outlet 10 of boiler body 9, and generating residual steam enters in back pressure turbine 1; Back pressure turbine 1 rotates under Steam Actuation; Simultaneously, back pressure turbine 1 is connected with the main shaft 5 of induced draught fan 6 by clutch 4, and induced draught fan 6 continues as boiler air draft under the drive of back pressure turbine 1; Generating drives dual-purpose motor to stop driving; The main shaft 5 of induced draught fan 6 initiatively drives generating to drive dual-purpose motor to rotate, and generates electricity.Thus realize the object of energy-conserving and environment-protective.
Be understandable that, above about specific descriptions of the present utility model, the technological scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
