Abstract
The utility model relates to a coaxial driving power device for a steam turbine engine, and the improvement of which is as follows: the device comprises a steam turbine, a motor, a clutch and a controller; the power axis of the motor is provided with two connecting ends, wherein one end is an input end while the other end is an output end; the input end is connected with an output axis of the steam turbine through the clutch; and the output axis of the steam turbine, the clutch and the input end of the power axis of the motor are electrically connected with the controller. The device utilizes the heat energy of afterheat steam to directly replace main current consuming apparatuses such as a blower and a water pump and the like which are commonly used in partial industrial enterprise adopting electric power for driving, thus obviously saving enterprise cost and efficiently improving utilization efficiency of energy.
Description
Technical field
The utility model relates to a kind of Power Drive Unit, specifically a kind of steam turbine motor Driven by Coaxial power plant.
Background technique
The industrial furnace flue gas has higher temperature, and exhaust heat boiler can be collected fume afterheat to produce steam.This afterheat steam generally is used for heating, lithium bromide refrigerating, steam turbine power generation or directly diffuses.The means of the follow-up utilization of afterheat steam are less in the prior art, and afterheat steam utilizes insufficient.In the process that adopts steam turbine power generation, in the energy conversion process of afterheat steam heat energy---electric energy---kinetic energy, the Conversion of energy link is more, causes energy loss bigger, has reduced the utilization ratio of waste heat steam.From the use of electric power, adopt steam turbine power generation, be subjected to the power department policy implication, electricity generation grid-connecting needs the power department approval and need pay certain electrical network usage charges, has certain inconvenience.Therefore, lack the effective way that makes full use of afterheat steam at present.
The model utility content
The purpose of this utility model just provides the little steam turbine motor Driven by Coaxial power plant of a kind of energy loss, to make full use of the heat energy of afterheat steam.
The utility model is achieved in that a kind of steam turbine motor Driven by Coaxial power plant, and its improvements are that this device comprises steam turbine, motor, clutch and controller; The line shaft of motor is provided with two connecting ends, and wherein an end is an input end, and the other end is an output terminal; Input end is connected with the output shaft of steam turbine by clutch, and the input end of the output shaft of steam turbine, clutch and motor power axle is electrically connected with controller.
The utility model adopts this structure, during system start-up, opens motor earlier, drives equipment operation, opens steam turbine then.Steam turbine is converted into rotating mechanical energy with steam thermal energy and is exported by output shaft.The output terminal of the output shaft of steam turbine, clutch and motor power axle is electrically connected with controller, in the process that the output shaft rotating speed promotes gradually, when turbine speed is raised to when identical with motor speed, the controller solenoidoperated cluthes make its engagement, make a rotating speed remain on level a little more than the motor rated speed.Thus, the equipment that driven with motor drive motor output shaft of steam turbine.When steam turbine self had fault or steam supply to cut off, turbine speed reduced.When steam turbine output shaft rotating speed was lower than the motor rated speed, the controller solenoidoperated cluthes were thrown off it, by its equipment that is driven of motor drive, equipment can be run well down.
The utility model directly replaces a part of electric energy to drive main current consuming apparatus such as blower fan commonly used in the industrial enterprise, water pump with the heat energy of afterheat steam, can significantly save entreprise cost, effectively improves energy utilization efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1,
This steam turbine motor Driven by Coaxial power plant comprise steam turbine 1, motor 3, clutch 2 and controller 6.The line shaft of motor 3 is provided with two connecting ends, and wherein an end is an input end 7, and the other end is an output terminal 8.Input end 7 is connected with the output shaft of steam turbine 1 by clutch 2, and the input end of the output shaft of steam turbine, clutch 2 and motor 3 line shafts is electrically connected with controller 6.
The output terminal of motor power axle links to each other with consumers such as blower fan, water pump 5 by speed-change gear box 4.
Compared with prior art, but adopt the not only utilization ratio of Effective Raise afterheat steam of the utility model, and And have compact conformation, floor space is little, investment is little, margin of safety does not subtract beneficial effect.
