Abstract

A centripetal wet-steam turbine, consisting of a flow part, a rotor, nozzle and rotor blades located on the impeller, and a condenser, characterized in that it has a vertical design, the rotor shaft is mounted on a tab bearing, and the condenser and the flow part are hermetically connected into a single design, and the flowing part consists of an impeller with impellers mounted on it and a nozzle apparatus.

Description

The utility model relates to the field of power engineering and can be used on autonomous decentralized power plants of low power, from 5 to 30 kW of electric and from 20 to 200 kW of thermal power.
Known steam turbine of low power K-17-15P (Steam turbines of low power KTZ / P 18 V.I. Kiryushin, N.M. Taranenko, E.P. Ogurtsova and others - M .: Energoatomizdat, 1987), which is a single-cylinder unit containing a steam distribution device (steam supply pipe to the steam chamber), a housing, a rotor with working blades (a shaft with working blades of the first crown) and nozzle blades, diaphragms, blades of working blades (working disk of the first crown). The turbine condenser is located in a separate housing. The turbine flow part consists of eight stages, the turbine rotor is solid forged, flexible.
The disadvantages of the steam turbine low power K-17-15P are:
- horizontal execution of this turbine complicates its assembly and manufacture of component parts;
- the capacitor located in a separate housing is leaky, and this increases the cost of ejection. The prototype of the utility model is the Utron P-0.1-1.3 / 0.2 steam turbine (http://www.turbopar.ru/proizvodstvo-turbin/100.html), which consists of a flow part including high, medium and low pressure cylinders. Also, the turbine contains a rotor, rotor blades and nozzle blades, diaphragms, rotor blades disks (turbine wheels). The turbine condenser is located in a separate housing.
The disadvantages of this steam turbine are:
- horizontal execution of this turbine complicates its assembly and manufacture of component parts;
- in the production of thermal energy, 2700 kg / h is consumed. steam, which is a significant limitation of the use of systems with this turbine by the mass consumer in decentralized areas.
The objective of the proposed utility model is the development of a centripetal wet-steam turbine with a sealed housing, in which there is a condenser and an electric generator of the turbine. The presence of a one-piece housing eliminates leakage of the working fluid from the inside of the wet-steam turbine.
The technical result of the proposed utility model is to reduce the cost of ejection, due to a single design of the condenser body and the humid-steam turbine generator, as well as to reduce the load on the thrust bearings, which makes it possible to use air-gas dynamic lobed bearings and, thus, get away from the traditional turbine oil lubrication. The vertical design of the wet-steam turbine greatly facilitates its assembly and manufacture of component parts, compared with the traditional horizontal design of the turbines. Also, a wet-steam turbine has a low steam flow rate (0.03 kg / s at 5 kW of electric power), in comparison with analogues, which significantly expands their use by the mass consumer.
The technical result of the utility model is achieved using a centripetal wet-steam turbine, consisting of a flow part, a rotor, nozzle and rotor blades located on the impeller, and a condenser, and having a vertical design, the rotor shaft is mounted on a tab bearing, and the condenser and flow part hermetically connected in a single design, and the flow part
consists of an impeller with impellers mounted on it and a nozzle apparatus.
The figure shows the design of a centripetal wet-steam turbine, consisting of a foundation frame 1 mounted on a flat horizontal surface to which a condenser body 2 with integrated ejection channels is attached (not shown in Fig.). The stiffener 3 is connected to the condenser body 2 and the foundation frame 1. The condensate drain pipe 4 is built into the condenser body 2 and the heat transfer surfaces 5 are connected to which the supply pipe 6 and the cooling water discharge pipe 7 are connected, a guide ring 8 is installed on the heat transfer surface 5. the base frame 1 is secured by bolts 9 to a support 10 to which the distribution grid 11 is attached. A row of rotor blades of the turbine wheel 13 is located on the rotor shaft 12. The rotor shaft 12 is mounted on a tab bearing (not shown in FIG.) . The housing of the capacitor 2 is connected to the housing of the flow part 14 by a flange connection (not shown in FIG.), Which is sealed by a gasket (not shown in FIG.). The body of the flowing part 14 is connected to the cover 15 of the steam chamber (not shown in FIG.), A flange connection 16. A static nozzle apparatus 17 and an end fitting for supplying steam 18 to the steam chamber (FIG. .not indicated). The centripetal case of a wet-steam turbine (not shown in FIG.) Consists of a condenser body 2, a flow chamber body 14, a steam chamber case (not shown in FIG.) And a cover 15, these elements are interconnected by flange connections 16 and 19.
Consider an example of a centripetal wet-steam turbine:
Acute steam, through the end fitting for supplying steam 18 to the steam chamber (not shown in FIG.), Enters the body of the flow part 14 and passes through the static nozzle apparatus 17 and enters the working blades of the turbine wheel 13, where the potential thermal energy of the steam is converted into mechanical the rotation energy of the shaft of the rotor 12 mounted on a lobe bearing (not indicated in FIG.), which allows maintaining high rotor speeds. Then the steam enters the distribution grid 11 and evenly enters the condenser body 2. Inside the condenser body 2, the waste steam transfers its heat to the heat exchange surfaces 5 and condenses, after which it is vented out using the condensate drain pipe 4. The guide ring 8 prevents the steam stream from passing by heat exchange surfaces 5. Inside the heat exchange surfaces 5, cooling water flows, which enters through the cooling water supply pipe 6 and is discharged through the cooling water discharge pipe 7. Through the ejection channels (not shown in FIG.), A vacuum is created in the condenser (not indicated in FIG.) During start-up, then during operation, the vacuum is maintained by the temperature of the cooling water.
Due to the fact that the turbine is designed vertically, assembly of the turbine and manufacture of its parts is simplified, in addition, the body of the flow part 14, the body of the capacitor 2, mounted on a foundation frame 1, bolted 9 to a support 10, connected by stiffeners 3, and a cover 15 the steam chamber (not shown in FIG.) is hermetically connected to a common housing (not shown in FIG.), via flange connections 16 and 19, which ensures the tightness of the condenser and the reduction of ejection costs.
