Abstract
The utility model discloses a system of recycling is retrieved to gland leak off relates to steam turbine technical field. Including vapor seal, monitor, excessive pressure balancing unit and low pressure feed water heater, the vapor seal passes through the pipeline and is connected with low pressure feed water heater, be equipped with monitor and excessive pressure balancing unit between vapor seal and the low pressure feed water heater in proper order. The problem of among the prior art gland leak off cause that a large amount of steam are arranged, noise pollution outward is solved, to leaking the equitable recycle of vapour, avoided the noise pollution and the wasting of resources, be favorable to energy saving and emission reduction work to be carried out, promote the unit benefit.
Description
Technical field
This utility model relates to steam turbine technology field, particularly relates to a kind of gland leak-off and reclaims
Reutilization system.
Background technology
In thermal power generation, Turbine Steam leak sealing vapour is main energy loss form.Such as Fig. 1
Shown in, in prior art, two grades of gland leak-offs of High Back Pressure Steam Turbine Units are rationally reclaimed, and cause big
Arrange outside amount steam, cause noisy environment to pollute, and be unfavorable for energy-saving and emission-reduction.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, it is provided that a kind of packing
Leakage vapour recycling system.Solve gland leak-off in prior art to cause outside a large amount of steam
Row, the problem of noise pollution.
The purpose of this utility model is achieved through the following technical solutions:
A kind of gland leak-off recycling system, including packing, monitor, crosses pressure balanced dress
Putting and low-pressure heater, described packing is connected with low-pressure heater by pipeline, described packing with
Monitor and overvoltage bascule it is sequentially provided with between low-pressure heater.
Preferably, also include check-valves, set between described overvoltage bascule and low-pressure heater
There is check-valves.
Preferably, also include electrically operated valve, between described packing and monitor, be provided with electrically operated valve.
Preferably, described packing is two grades of packings of High Back Pressure Steam Turbine Units.
Preferably, described monitor includes temperature monitor and pressure monitor.
This utility model has the advantages that
Gland leak-off recycling system of the present utility model, utilizes Turbine Steam leak sealing vapour,
Heat-setting exit of pump water quality, decreases the low-pressure heater utilization to external initial steam.Du
Absolutely steam turbine leak in a large number vapour externally discharge, noise pollution and the problem of the wasting of resources, be conducive to
Energy-saving and emission-reduction work is carried out, and promotes Benefit of Unit.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of gland leak-off in prior art；
Fig. 2 is the schematic diagram of gland leak-off recycling system provided by the utility model.
Wherein: 1 is steam turbine；2 is monitor；3 is overvoltage bascule；4 is low pressure
Heater；5 is check-valves；6 is electrically operated valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example
It is only used for explaining this utility model, is not intended to limit scope of the present utility model.
As in figure 2 it is shown, present embodiments provide a kind of gland leak-off recycling system,
Including packing, monitor 2, overvoltage bascule 3 and low-pressure heater 4, described packing leads to
Piping is connected with low-pressure heater 4, is sequentially provided with between described packing and low-pressure heater 4
Monitor 2 and overvoltage bascule 3.
Steam turbine 1 gland leak-off is caused low-pressure heater 4 by pipeline by this system.After recovery
A large amount of steam for heat-setting exit of pump water quality, decrease low-pressure heater 4 to external
The utilization of initial steam.Stop steam turbine 1 to leak vapour in a large number and externally discharge and noise pollution, to money
Source carries out Appropriate application.
Here, it is preferable that described monitor 2 includes temperature monitor and pressure monitor.
Monitor 2 is for monitoring the steam pressure of gland leak-off, temperature etc..Add when pressure exceedes low pressure
During hot device 4 operating pressure, overvoltage bascule 3 can adjust steam pressure automatically.
Preferably, check-valves 5, described overvoltage bascule 3 and low-pressure heater 4 are also included
Between be provided with check-valves 5, prevent other vapour source of low-pressure heater 4 from entering packing along pipeline.
Preferably, also include electrically operated valve 6, be provided with electronic between described packing and monitor 2
Valve 6.Electrically operated valve 6 is closed when steam turbine 1 starts or stops transport, and is used for
Isolation other vapour source of low-pressure heater 4 enters packing along pipeline, echoes with check-valves 5 phase,
Play dual anti-back-steam effect.
Preferably, described packing is two grades of packings of High Back Pressure Steam Turbine Units.
In sum, gland leak-off recycling system of the present utility model, utilize steamer
Machine 1 gland leak-off, heat-setting exit of pump water quality, decrease low-pressure heater 4 to external
The utilization of initial steam.Stopped steam turbine 1 leak in a large number vapour externally discharge, noise pollution and resource
The problem of waste, beneficially energy-saving and emission-reduction work is carried out, and promotes Benefit of Unit.
