Abstract
A kind of back pressure turbine system, comprises the major steam line to back pressure turbine supplying high temperature high pressure steam, and described major steam line connects boiler; The steam-expelling port of described back pressure turbine connects steam cooling depressurizing system by pipeline, and described steam cooling depressurizing system connects vapour condenser by pipeline, and described vapour condenser and heat user pass through pipeline connection; A kind of back pressure turbine system of the present utility model, the basis of existing system adds decrease temperature and pressure system, the steam of the steam and steam turbine discharge of boiler being arranged air is by decrease temperature and pressure system, then the steam after decrease temperature and pressure is supplied to heat user, solves the problem of medium-loss and the noise pollution existed in existing system with this.
Description
Technical field
The utility model relates to steam turbine technology field, specifically a kind of back pressure turbine system.
Background technique
Existing back pressure turbine system, due to system custom and system layout reason, conventional Starting mode is that main steam is before reaching rolling parameter, by boiler side to empty outlet valve to steam row air to regulate the temperature and pressure of boiler develops steam vapor, to steam turbine red switch after steam increasing temperature and pressure, during red switch, steam turbine is through outlet valve exhaust steam, drops to after uniform temperature, pressure be incorporated to heat supply network until steam.In the process of steam row air, cause the loss of working medium, the noise that steam discharge produces simultaneously causes severe contamination.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of novel back pressure turbine system.
The utility model solves its technical problem by the following technical solutions.
A kind of back pressure turbine system, comprises the major steam line to back pressure turbine supplying high temperature high pressure steam, and described major steam line connects boiler; The steam-expelling port of described back pressure turbine connects steam cooling depressurizing system by pipeline, and described steam cooling depressurizing system connects vapour condenser by pipeline, and described vapour condenser and heat user pass through pipeline connection; Described decrease temperature and pressure system comprises the discharge bypass of steam turbine, the bypass of high pressure main steam, the bypass of middle pressure main steam, the bypass of low pressure main steam, described discharge bypass connects the bypass of high pressure main steam, main steam bypass is pressed in the outlet pipe connection of described high pressure main steam bypass, the outlet pipe of described middle pressure main steam bypass connects the bypass of low pressure main steam, and the outlet pipe of described low pressure main steam bypass connects vapour condenser; Described boiler be connected to the bypass of high pressure main steam to empty outlet valve by pipeline.
A kind of back pressure turbine system of the present utility model, the basis of existing system adds decrease temperature and pressure system, the steam of the steam and steam turbine discharge of boiler being arranged air is by decrease temperature and pressure system, then the steam after decrease temperature and pressure is supplied to heat user, solves the problem of medium-loss and the noise pollution existed in existing system with this.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of back pressure turbine system, comprises the major steam line 11 to back pressure turbine 2 supplying high temperature high pressure steam, and described major steam line 11 connects boiler 1; The steam-expelling port of described back pressure turbine 2 connects steam cooling depressurizing system by pipeline, and described steam cooling depressurizing system connects vapour condenser 6 by pipeline, and described vapour condenser 6 passes through pipeline connection with heat user 7; Described decrease temperature and pressure system comprises the discharge bypass 21 of steam turbine, high pressure main steam bypass 3, middle pressure main steam bypass 4, low pressure main steam bypass 5, described discharge bypass 21 connects high pressure main steam bypass 3, main steam bypass 4 is pressed in the outlet pipe connection of described high pressure main steam bypass 3, the outlet pipe of described middle pressure main steam bypass 4 connects low pressure main steam bypass 5, and the outlet pipe of described low pressure main steam bypass 5 connects vapour condenser 6; Described boiler 1 be connected to high pressure main steam bypass 3 to empty outlet valve 8 by pipeline.
The high temperature and high pressure steam that boiler 1 produces, needs, by the temperature and pressure to empty outlet valve 8 steam regulation, to be connected to decrease temperature and pressure system to empty outlet valve 8, can to the vapor collection recycling of row's air; Back pressure turbine 2 rotates under the promotion of steam, steam leads to decrease temperature and pressure system by discharge bypass 21 subsequently, successively by after high pressure main steam bypass 3, middle pressure main steam bypass 4, low pressure main steam bypass 5 decrease temperature and pressure, in condenser 6, be condensed into liquid state again, heat user 7 can be supplied to subsequently.Back pressure turbine system of the present utility model, solves prior art Problems existing, has stronger practicability.
