Description
Technical field
The utility model belongs to enclosed steam turbine decompressor technical field, and in particular to a kind of to utilize steam waste heat ladder mould
The steam turbine reducing-and-cooling plant of formula.
Background technique
The initial steam that steam turbine generates is larger due to temperature, pressure, it is therefore desirable to which carrying out cooling decompression just to it can mention
Heat user is supplied to use.It is traditional frequently with the pressure and temperature reducing for for example carrying out initial steam with temperature-decreased pressure reducer, throttle style etc.,
But this mode causes the waste of the energy.
Utility model content
The utility model provides a kind of steam turbine reducing-and-cooling plant using steam waste heat ladder mode, existing to solve
The problem of technology.
The technical solution of the utility model are as follows:
A kind of steam turbine reducing-and-cooling plant using steam waste heat ladder mode, it is characterised in that: including extraction turbo
Machine, small steam turbine and sludge drying device, the extraction steam turbine are connected with the small steam turbine by pipeline, institute
It states small steam turbine to be connected with the sludge drying device, the small steam turbine receives the new steaming of extraction steam turbine discharge
Vapour, and generated electricity using initial steam, so that initial steam pressure and temperature reducing, the steam of the small steam turbine discharge enters sludge drying dress
It sets, is used for supplying sludge drying and processing.
It further, further include condensate tank, condensation water inlet and the sludge drying device of the condensate tank
Condensation water out is connected, and for receiving cooling steam, the condensation water out of the condensate tank is connected by condensing water conduit
It is connected to power plant's oxygen-eliminating device, further to be utilized.
The beneficial effects of the utility model are:
The utility model in the way of steam turbine pressure and temperature reducing, instead of it is traditional with temperature-decreased pressure reducer and throttling set into
The mode of row steam temperature reducing and pressure reducing not only can be reduced steam thermal energy energy waste, but also can further have been utilized to initial steam, with
Meet production requirement, sufficiently realizes the energy-saving and utilization of resources.
Detailed description of the invention
Fig. 1 is traditional temperature-decreased pressure reducer figure；
Fig. 2 is the steam turbine reducing-and-cooling plant figure using steam waste heat ladder schema.
Specific embodiment
As shown in Figure 1, since initial steam original pressure, the temperature that extraction steam turbine generates are more than steaming needed for heat user
Stripping temperature and pressure, therefore pressure and temperature reducing is carried out using desuperheating water and throttling set on traditional approach.Subtracting in the traditional approach
Temperature-decreased pressure reducer will cause the waste of heat resource.
As shown in Fig. 2, the utility model provides a kind of steam turbine reducing-and-cooling plant using steam waste heat ladder mode,
Including extraction steam turbine, small steam turbine, sludge drying device and condensate tank, the extraction steam turbine with it is described small-sized
Steam turbine is connected by pipeline, and the small steam turbine is connected with the sludge drying device.Using small steam turbine into
Row pressure and temperature reducing, the small steam turbine are generated electricity using the initial steam of extraction steam turbine discharge, while it is dirty that steam supply is discharged
Mud drying unit, to be used for sludge drying and processing.The condensation water inlet of the condensate tank and coagulating for the sludge drying device
It bears water outlet to be connected, for receiving cooling steam, the condensation water out of the condensate tank is connected by condensing water conduit
To power plant's oxygen-eliminating device, utilize cooling Steam Recovery to power plant's oxygen-eliminating device further, which obviate in traditional approach
The waste of resource, energy caused by using temperature-decreased pressure reducer.
Embodiment one:
The utility model is implemented in sludge drying treatment plant.The pressure 0.8Mpa being discharged using power plant's extraction steam turbine,
The factory steam that 300 DEG C of temperature is supplied to small-sized 300kw steam turbine, the steam discharge of the small-sized 300kw steam turbine as vapour source
Pressure is 0.5Mpa, exhaust temperature is 200 DEG C, carries out sludge drying and processing, cooling Steam Recovery to power plant with the steam
Oxygen-eliminating device further utilizes.
