Abstract
The present invention discloses a kind of steam turbine building arragement construction suitable for burning power plant, present invention innovation uses reactionary style axial exhaust turbine, make longitudinal correct, the single layer arrangement of the steam turbine in workshop, Steam Turbine center absolute altitude is installed on 2.8 meters of layers, and 0.6 meter of foundation elevation, no 4.5 meters of layers operate layer, no steam turbine is hung, generator amature maintenance can be evacuated to outdoor, and economical material can be used in steam turbine building alien invasion, and steam turbine building top layer top may be designed to visit leisure place.
Description
Technical field
The present invention relates to municipal solid wastes incineration power generation fields, are the unconventional arragement construction of steamer computer room, Ci Zhongbu
Main building cost and its up-front investment can be reduced by setting, while greatly improve the plant thermal efficiency of garbage burning factory.
Background technique
Turbo-generator Set is the important equipment in garbage burning factory, and conventional steam turbine is lower steam discharge arrangement, and equipment is put
It is placed on 8 meters of operating layers, condenser is placed on the downside of turbine discharge mouth, since steam discharge will be by can just drain into after a corner
Condenser, this considerably increases the losses of the steam discharge of steam turbine, reduce the efficiency of steam turbine；Since operating layer is higher, lubricating oil
The arrangement stood is also relatively high, and centre, which must be provided with 4.5 meters of layer platforms just, can rise to 8 meters of layers, so conventional power plant steam turbine building is equal
Using rebuilding, which substantially increases the investment costs of civil engineering structure, can solve using reactionary style axial exhaust turbine
This problem, while reactionary style axial exhaust turbine can also be improved the efficiency of steam turbine.
The height of turbine efficiency directly affects generated energy, so the efficiency for improving steam turbine is to improve plant thermal efficiency
Important way, while the more raising steam turbine energy-saving and environment-friendly, garbage burning factory uses at present can also be played the role of
The mode of efficiency has following several: (1) slow-speed of revolution reaction turbine；(2) high revolving speed impulse turbine.(3) high revolving speed is anti-
Dynamic formula steam turbine；(4) high and low rotating speed impulsion, reaction combination turbine.The above several ways are the forms using lower steam discharge,
It also there is no the Engineering Projects of axial exhaust.
Summary of the invention
Mesh of the invention it is: (1) reduces the height of main building, saves infrastructure cost；(2) steam turbine is improved
Efficiency improves economy of power plant benefit；(3) it saves equipment investment cost, save equipment operation maintenance cost.
The specific technical solution of the present invention is: a kind of steam turbine building arragement construction suitable for garbage burning factory, and steam turbine is vertical
To correct, single layer arrangement, 38 meters of single steam turbine longitudinal size, 2 steam turbine total lengths are 72.2 meters；14 meters of lateral dimension, vapour
Wheel unit centre absolute altitude is installed on 2.8 meters of layers, and directly from 0 meter of basis installation, steam turbine building top layer absolute altitude is by 8.5 meters of designs.
Further, the maintenance door that setting truck crane in steam turbine building two sides passes in and out, centre setting access path, facilitates truck crane
Enter in steam turbine building at any time, the maintenance and maintenance of turbine generator machine equipment rotor and components are directly carried out in 0 meter of layer, are no longer needed to
In addition a set of steam turbine is individually arranged to hang.
Further, the rotor of steam turbine generator is directly drawn to vapour by the reserved gate of power generation drive end unit out of workshop
It is overhauled on the outside of computer room, without additional reserved pumping rotor space, which reduces the span of steam turbine building and entire areas.
Further, lube plant is directly arranged at zero meter of layer, cancels the 4.5 meters of layer platforms routinely arranged.
Color steel plate or other economic and reliables may be selected without bearing equipment, building and alien invasion in steam turbine building single layer arrangement, roof
Material.
The income effect that the present invention innovates includes: the height that (1) reduces main building, with saving the mesh of construction cost.It is conventional
Workshop and innovation workshop size comparison are as follows:
| Serial number | Title | The double-deck main building (M) | Single layer main building (M) |
| 1 | Operate layer height | 8.5 | 0.6 |
| 2 | Roof absolute altitude | 21 | 8.5 |
| 3 | 2 machine steam turbine building overall lengths | 65.6 | 72.2 |
| 4 | Overall width | 24.8 | 22.3 |
(2) Steam Turbine whole efficiency about 7% (30MW unit) is improved, increases economy of power plant benefit.(3) it is not provided with steam turbine
It hangs, saves equipment investment early period and the operation maintenance cost in later period, save overhaul life cost.(4) it is easily installed, improves construction
Speed reduces the construction period.
Detailed description of the invention
Fig. 1 is floor plan of the present invention.
Fig. 2 is section layout drawing of the invention.
In figure: 1, steam turbine 2, condenser 3, generator 4, condensate pump 5, vacuum pump 6, feed pump 7, low-pressure heater；
8, gear-box；9, water tank.
Specific embodiment
In conjunction with shown in attached drawing 1 and Fig. 2: steam turbine 1 is longitudinally arranged, and condensate pump 4 is arranged in the solidifying pump hole of 2 front side of condenser
In, absolute altitude is at -2 meters, and pump hole top can use checker plate or flase floor be covered, that is, the problem of cavitation for solving solidifying pump is again beautiful
It sees.
Solidifying pump left side is condenser 2, and condenser 2 is directly connected to steam turbine 1, generator 3, gear-box 8, and equipment can be whole
Body fortune causes in-site installation, is used uniformly common backplane, entire bottom block is in an independent concrete foundation, and foundation elevation is only
It is 0.6 meter.
Since the foundation elevation and center absolute altitude of steam turbine 1 are all preferably minimized place, so to the lubrication of 1 bearing of steam turbine
Petrol station, can be in steam turbine side arrangement without high level is put into.
Vacuum pump 5, feed pump 6 and drain tank 9 are placed on zero meter of deaerator bay A-B axis, mutual with Turbo-generator Set 3
It answers.4.5 meters of layers of A-B axis are designed to cable and pipe sandwich as conventional model burning power plant, use for pipe arrangement.A-
8.5 meters of layers of B axle are designed to that visit corridor, left side can be designed to that windowpane visits waste incineration line, and right side is designed to glass door
And windowpane, 8.5 meters of layer roofs of steam turbine building can be led to.The roof layouts of steam turbine building can place several sets at leisure place
Sunshade and the sports centers such as tables and chairs or shuttlecock, table tennis, can also be designed to green belt kind plant and gourd, fruit and vegetable
Deng.14 meters of layers of A-B axis are deaerator bays, place oxygen-eliminating device and associated conduit attachment.
