Description

Technical Field

[0001] The utility model relates to the technical field of steam turbines, in particular to a steam chamber structure of a steam turbine. Background Art

[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle and becomes an accelerated airflow, which is then sprayed onto the blades, causing the rotor with the blade rows to rotate and perform work externally. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship power devices. When a steam turbine is used, it is necessary to use the steam chamber to drive the steam energy storage and transmit it to the inside of the steam turbine.

[0003] When the steam turbine is in use, steam is transmitted to the interior of the steam turbine through the steam chamber. At the same time, the steam contains kinetic energy and high-humidity gas. When the water content in the steam is too high and is transmitted to the interior of the steam turbine, the water content in the steam contacts the steam engine and vaporizes to produce liquid. When the liquid accumulates inside the steam turbine, the excess liquid will interfere with the use of the steam turbine. For this reason, we propose a steam chamber structure for a steam turbine.

[0009] Preferably, a second one-way valve is installed inside the auxiliary transmission pipe, and a sealing gasket is installed inside the second one-way valve toward the inside of the steam chamber.

[0010] Preferably, a sealing sleeve is installed inside the steam exhaust pipe, and the sealing sleeve is attached to the outside of the lower end of the fan blade, and a blade is installed outside the fan blade to fit the outside of the steam exhaust pipe.

[0012] Compared with the steam chamber structure of the existing steam turbine, the utility model has the following beneficial effects:

[0013] 1. The steam chamber structure of the steam turbine is provided with a bottom baffle plate at the lower end of the steam chamber, and a water-absorbing sponge is arranged between the steam chamber and the bottom baffle plate. When the steam is transported to the interior of the steam chamber for energy storage, the steam contacts the oblique baffle plate, and the liquid is transported to the interior of the water-absorbing sponge. The liquid can be transported to the interior of the liquid collecting box through the water-absorbing sponge. Then, when the steam is transported to the interior of the steam turbine body to ensure sufficient energy, the content of the liquid in the steam transported to the interior of the steam turbine body is reduced, so as to avoid excessive water content in the steam and transporting it to the interior of the steam turbine body, which affects the rotation efficiency of the steam turbine.

[0014] 2. The steam chamber structure of the steam turbine is installed at the end of the turbine body through the steam exhaust pipe. The steam is transported to the inside of the fan blades. When the steam is discharged and contacts the fan blades, the rotation of the fan blades can reduce the steam discharge speed, increase the reserved time of steam in the turbine body, and then improve the steam utilization rate.

A fan blade 15 is installed inside the steam discharge pipe 14. A first one-way valve 16 is installed at the upper end of the steam discharge pipe 14. The fan blade 15 and the first one-way valve 16 block the inside of the turbine body 1, reduce the steam discharge efficiency, and thereby improve the steam workmanship rate.

[0023] See also Figure 2 The steam chamber 3 is located on one side of the steam turbine body 1, and the steam discharge chamber 5 is arc-shaped inside the steam chamber 3. The steam chamber 3 is installed on one side of the steam turbine body 1. At the same time, the steam transmission pipe 8 drives the steam to be transported to the inside of the steam discharge chamber 5. At the same time, through the auxiliary conduction of the first energy storage chamber 6 and the second energy storage chamber 7, the steam can be transported to the inside of the auxiliary transmission pipe 2. At the same time, the steam discharge chamber 5 is arc-shaped inside the steam chamber 3. When the steam is transported to the inside of the steam turbine body 1 after passing through the auxiliary transmission pipe 2, the steam transportation efficiency can be improved.

[0024] See also Figure 3 The liquid discharge pipe 10 is located at the upper end of the oblique baffle 11. The liquid discharge pipe 10 is arranged in an oblique direction between the steam chamber 3 and the first energy storage chamber 6. The oblique baffle 11 is installed in the middle of the upper end of the liquid discharge pipe 10. At the same time, when the steam passes through the inside of the oblique baffle 11, when the steam passes through the oblique baffle 11, the excess liquid inside the steam is blocked and slides downward. At the same time, the steam can be transported to the inside of the water-absorbing sponge 12 through the liquid discharge pipe 10.

[0025] See also Figure 3 A water outlet is provided between the liquid collecting box 13 and the steam chamber 3. The absorbent sponge 12 is arranged at the upper end of the liquid collecting box 13, and is installed at the lower end of the steam chamber 3 through the liquid collecting box 13.

A blade is installed outside the fan blade 15 and fits to the outside of the steam exhaust pipe 14. The fan blade 15 is installed inside the steam exhaust pipe 14. At the same time, when the steam is transported to the inside of the turbine body 1 and works, the steam is discharged through the steam exhaust pipe 14. At the same time, when the discharged steam passes through the fan blade 15, the fan blade 15 can slow down the passing steam, thereby increasing the gas reservation time inside the turbine body 1, thereby increasing the power generation rate.

[0028] See also Figure 4 The first one-way valve 16 is arranged at the upper end of the fan blade 15, and the end of the first one-way valve 16 extends to the interior of the steam generator. The first one-way valve 16 is installed on the upper part of the fan blade 15. The first one-way valve 16 effectively drives the discharged steam to block and prevent steam reflux. At the same time, the liquid discharged through the steam discharge pipe 14 flows back to the interior of the steam generator, thereby driving the liquid to be recycled.

[0029] Working principle: When in use, steam is transported to the interior of the steam chamber 3 through the steam transmission pipe 8. At the same time, a partition plate 4 is installed inside the steam chamber 3. The partition plate 4 drives the steam to be transported to the interior of the turbine body 1 in an arc-shaped surface, thereby increasing the speed of steam being transported to the interior of the turbine body 1. At the same time, a liquid discharge pipe 10 is installed inside the steam discharge chamber 5. The liquid discharge pipe 10 blocks the passing steam and blocks excess liquid in the steam.
