Description
Technical field
The utility model relates to a kind of layout loop of blower fan high-efficiency operation of connecting.
Background technology
The ventilation blower of coal-fired power station boiler one general configuration is divided into pressure fan, air-introduced machine, primary air fan, desulphurization devices etc.Pressure fan, primary air fan are the burnings by delivering to boiler furnace participation fuel after air pressurized, and the flue gas after fuel combustion is discharged into chimney to air through dedusting, the process of desulphurization and denitration device by air-introduced machine, desulphurization devices.The operational efficiency of blower fan is relevant to the design efficiency of fan body, relevant with equipment place system head characteristics in addition on the one hand.The operating condition point efficiency of Fan Equipment is actual is the Performance Characteristics efficiency curve of blower fan and the crosspoint of place system head characteristics curve.
Usefulness transformation once improved because the Air Pollutant Emission Index of constantly keeping under strict control carries out environmental protection equipment in coal-burning power plant, generally adopted the arrangement of air-introduced machine+desulphurization devices series connection to realize fume emission.Sometimes also heat exchanger, desulfurization, cleaner etc. can be arranged between air-introduced machine and desulphurization devices.
Thermal generation unit electric load is often because there is significantly peak valley change in the different time demand of electricity consumption side or electrical network dispatch of unit load and other factors in addition, correspondence causes flow rate of fan parameter needed for system significantly to change, if reasonable distribution adjusts the operational factor of each blower fan, the energy conservation object improving fan operation efficiency can be reached.
Utility model content
The purpose of this utility model is exactly to solve the problem, and proposes the layout loop of a kind of blower fan high-efficiency operation of connecting of the bypass duct setting up blower fan.
To achieve these goals, the utility model adopts following technical scheme:
To connect the layout loop of blower fan high-efficiency operation, comprising: blower fan one; Blower fan one outlet is provided with blower fan two inlet conduits, and blower fan two inlet baffle door is located in described blower fan two inlet conduits, and blower fan two inlet baffle door can folding, and when blower fan two inlet baffle door is opened, blower fan two inlet conduits is connected with fan outlet air channel.
Bypass inlet air channel is connected with described blower fan two inlet conduits, described bypass inlet air channel is provided with bypass air channel barrier door, when bypass air channel barrier door is opened, bypass inlet air channel is connected with by-pass damper door outlet conduits, and by-pass damper door outlet conduits is connected with fan outlet air channel.
Blower fan two is provided with between described blower fan two inlet baffle door and fan outlet air channel.
When bypass air channel barrier door is closed, blower fan two inlet baffle door is opened, blower fan one and blower fan two series operation;
When bypass air channel barrier door is opened, blower fan two inlet baffle door is also opened, two air channels work simultaneously;
When blower fan two breaks down, blower fan two inlet baffle door can be closed, open bypass air channel barrier door, ensure the normal operation of device systems.
Blower fan one outlet conduits can be furnished with heat exchanger, desulfurating dust-removing equipment to blower fan two inlet baffle air channel in front of the door.
Described bypass inlet duct cross-section and bypass air channel barrier door are rectangle, circle or oval.
Described bypass air channel barrier door and blower fan two inlet baffle door are along the capable of opening and closing baffle ventilation door of rotating shaft or lock gate hatch.
The beneficial effects of the utility model are: the bypass air channel in this device and baffle door, and structure is simple, flexible and convenient to use, and may be used for transformation in in-service device systems and implement, technique is simple, and improvement cost is low.According to operating condition or the condition of system, open, adjust, close bypass air channel control baffle door, take the mode of single blower fan+bypass or 2 Fans series operations, the operational factor of reasonable distribution blower fan and state, reach the target improving fan operation efficiency.When blower fan two breaks down, open by-pass damper, can ensure that system and miscellaneous equipment can continue to run, improve the reliability of system.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model embodiment.
Wherein, 1. blower fan one, 2. blower fan two inlet conduits, 3. bypass inlet air channel, 4. bypass air channel barrier door, 5. by-pass damper door outlet conduits, 6. fan outlet air channel, 7. blower fan two, 8. blower fan two inlet baffle door.
Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, a kind of layout loop of blower fan high-efficiency operation of connecting, comprising: blower fan 1; Blower fan 1 export department is connected to blower fan two inlet conduits 2, blower fan two inlet baffle door 8 is located in described blower fan two inlet conduits 2, blower fan two inlet baffle door 8 can folding, bypass inlet air channel 3 is connected with described blower fan two inlet conduits 2, described bypass inlet air channel 3 is provided with bypass air channel barrier door 4, by-pass damper door outlet conduits 5 is connected with fan outlet air channel 6, is provided with blower fan 27 between described blower fan two inlet baffle door 8 and fan outlet air channel 6.
