Abstract
The utility model discloses a vacuum unit configuration system for thermal power factory, including liquid ring vacuum pump group of every unit condenser configuration, roots water ring vacuum pump group of the outer rematch of liquid ring vacuum pump group, wherein liquid ring vacuum pump group is used for the unit to establish the reserve of vacuum and normal operating, and roots water ring vacuum pump organizes and maintain the vacuum when unit normal operating, the utility model discloses compare energy -saving 70%~80% with traditional liquid -ring type vacuum pumping system, compare with indivedual technological transformation power plant and reduce by a liquid ring vacuum pump group, practice thrift investment and simplified system.
Description
Technical field
The utility model is related to a kind of configuration system of the vacuum pump set for thermal power plant.
Background technology
In power plant, vacuum affects larger on gross coal consumption rate.
, if vacuum often improves 1kpa, corresponding gross coal consumption rate declines 2.6g/kwh taking 300-350mw unit as a example.
The vaccum-pumping equipment that generation current factory commonly uses is water-jet pump and water ring pump, and the former is gradually substituted by the latter, tradition
Pendular ring type pumped vacuum systems, it is highly attenuating obvious that high energy consumption, vacuum are risen by environment temperature.The performance of water ring vacuum pump and aspirated gas
Temperature of the state (pressure, temperature) of body and working solution etc. is relevant.By " limit swabbing pressure " affected in running simultaneously, held
Easily in impeller surface generation local gas hammer phenomenon, operation noise is very big and blade can be made to produce very big tension, long-time fortune
Row is easily caused the fracture of blade, threatens the safe operation of unit.
A kind of thermal power plant condenser vacuum of Application No. 2012200640292 maintains system, also includes: vacuum dimension
Hold system, described vacuum maintains system to include: air inlet pipeline, air inlet hand-operated valve, vavuum pump, outlet pipe；Described air inlet pipeline,
Air inlet hand-operated valve, vavuum pump, outlet pipe are sequentially connected；Described air inlet pipeline inlet end connects condenser outlet side, described go out
Air pipe outlet side connects pumped vacuum systems assembly outlet side.The utility model system mainly has efficient vacuum pump and related pipe valve
Constitute, it and conventional vacuum pumping pump system parallel connection, reach the purpose of energy-conservation.
Fig. 1 is that 350mw coal unit condenser 1 pumped vacuum systems configures, by the first liquid ring vacuum pump group 21 and second
Liquid ring vacuum pump group 22 supply condenser 1 works.For setting up vacuum as early as possible, open two liquid-ring vacuum pumps 21/22 during machine and throw simultaneously
Entering. this configuration is deposited on-stream appearance and is wasted the phenomenons such as the energy.
" Roots's Water-ring vacuum pump group " nearly 2 years individual power plants have carried out technological transformation, as shown in Fig. 2 generally doing at home
Method is by the first liquid ring vacuum pump group 21 and the second liquid ring vacuum pump group 22, is further added by Roots's Water-ring vacuum pump group 3 and supplies
Work to condenser 1.Liquid ring vacuum pump group sets up vacuum and normal standby, the Roots's Water-ring vacuum pump group 3 run for unit
Maintain vacuum when condenser 1 normally runs, so using the phenomenon having occurred as soon as mismatch waste.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of vacuum machine for thermal power plant
Group configuration system.
Technical scheme for this utility model solution is that a kind of vacuum pump set for thermal power plant configures system, bag
Include every condenser configure a liquid ring vacuum pump group it is characterised in that: mate a Roots outside described liquid ring vacuum pump group again
Water-ring vacuum pump group, wherein liquid ring vacuum pump group set up vacuum and normal standby, the Roots's water ring vacuum pump running for unit
Group maintains vacuum when unit normally runs.
Beneficial effect:
The utility model can save energy 70%～80% compared with traditional Pendular ring type pumped vacuum systems, with indivedual technological transformation power plant
Compare one liquid ring vacuum pump group of minimizing, investment reduction simultaneously simplifies system.
Brief description
Fig. 1 is 350mw coal unit evacuation system for steam condenser conventional arrangement.
Fig. 2 is configuration after the transformation of 350mw coal unit evacuation system for steam condenser.
Fig. 3 is 350mw coal unit evacuation system for steam condenser new arrangement.
In figure 1 is condenser, and 2 is liquid ring vacuum pump group, and 21 is the first liquid ring vacuum pump group, and 22 is the second liquid-ring vacuum pump
Group, 3 is Roots's Water-ring vacuum pump group.
Specific embodiment
The utility model is as shown in Figure 3.
A kind of vacuum pump set configuration system for thermal power plant, configures a liquid ring vacuum including every condenser 1
Pump group 2, described liquid ring vacuum pump group 2 is outer to mate Roots's Water-ring vacuum pump group 3 again, and wherein liquid ring vacuum pump group 2 is used for machine
Group set up vacuum and normal run standby, Roots's Water-ring vacuum pump group 3 maintains vacuum when unit normally runs.
The configuration of the utility model vavuum pump, with respect to reworked configuration, decreases a liquid-ring vacuum pump, liquid-ring vacuum pump 2
It is to open when vacuum set up by machine in unit to come into operation, only do standby during normal operation.
Configuration therefore of the present utility model, considers to have opened the requirement of time, Ke Yifang in the type selecting of liquid ring vacuum pump group 2
Big one-level.
Claims (1)
