At the same time, when the steam turbine is started, a vacuum is established by a vacuum pumping device. Specifically, when the steam turbine is running, it is arranged on the same layer as the condenser. The exhaust steam after the steam turbine does work is the upper steam. The condenser vacuum pumping equipment originally used a water jet vacuum pump, which continuously extracts the air and non-condensable gas contained in the steam that leaks into the condenser, keeping the condenser always in a relatively high vacuum state.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A high-efficiency energy-saving steam turbine comprises a steam turbine body 1, an air outlet end of the steam turbine body 1 is connected to a condenser body 2, and a liquid collecting box 3 is connected to the middle position of the bottom end of the condenser body 2, a side position of the liquid collecting box 3 is connected to a separation chamber 6, and a conical part 7 is provided on one side of the interior of the separation chamber 6, and a flow-uniforming plate 8 is provided on the side of the conical part 7 close to the middle of the separation chamber 6, a sealing support frame 9 is clamped on the upper inner side of the separation chamber 6, and molding brackets 10 are fixedly connected to the four corner ends of the bottom of the sealing support frame 9, an adsorption cotton material 11 is clamped between the two groups of molding brackets 10, a bracket 12 is fixedly connected to the top end of the sealing support frame 9, and a telescopic rod 13 is provided at the inner middle position of the bracket 12, and a pressure plate 14 is connected to the movable end of the telescopic rod 13.

[0021] like Figure 1 As shown, a steam elbow 16 is connected to the top of the steam turbine body 1, and a circulating water pipe 15 is connected to the lower position on the other side of the liquid collecting box 3. By setting the circulating water pipe 15, an external circulating water pump will extract the fluid in the liquid collecting box 3 through the circulating water pipe 15 after starting the operation, and send it into the circulating pipeline for recycling; a side of the separation chamber 6 away from the liquid collecting box 3 is connected to an exhaust pipe 4, and the exhaust end of the exhaust pipe 4 is connected to an oil ring vacuum pump 5. When the entire vacuum system is connected, the exhaust pipe 4 will mainly play the role of a transfer pipeline.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the center point of the conical member 7 and the center point of the uniform flow disk 8 are arranged to overlap, and the uniform flow disk 8 and the adsorbent cotton material 11 are arranged in close contact. When water vapor and air are extracted from the interior of the liquid collecting box 3 together and sent into the interior of the separation bin 6 in advance, the conical member 7 and the uniform flow disk 8 will guide and uniformly process the water vapor and air in turn so that the equipment can separate and recycle them; the shape of the molding bracket 10 is an "L"-shaped structure, the adsorbent cotton material 11 and the pressure plate 14 are arranged adjacent to each other in the upper and lower positions, the bottom end surface of the sealing support frame 9 is provided with a groove for clamping the pressure plate 14, the movable end of the telescopic rod 13 extends into the interior of the sealing support frame 9, and the shape of the bracket 12 is a "U"-shaped structure. The separation bin 6 and the liquid collecting box 3 are connected by a short inclined tube. When the adsorbent cotton material 11 is installed, the two groups of "L"-shaped molding brackets 10 will achieve the molding limitation of the adsorbent cotton material 11 by wrapping the corners.

[0023] Working process: The electric energy required by the equipment in the utility model for startup and operation all comes from an external power supply. When the steam turbine is used for power generation, as steam with a certain pressure and temperature enters the interior of the steam turbine body 1 through the steam elbow 16, the rotor inside the steam turbine body 1 will rotate under the high-speed impact of the steam, thereby converting thermal energy into mechanical energy, providing mechanical kinetic energy for the operation of the entire generator set. At the same time, as the steam entering the interior of the steam turbine body 1 gradually leaks into the condenser body 2, the entire vacuum system will use the oil ring vacuum pump 5 instead of the traditional water jet pump to form a new energy-saving vacuum system, so that the equipment can convert the steam through the steam elbow 16. The non-condensable gas contained in the steam is continuously extracted, and the entire vacuum operation is characterized by high efficiency and low energy consumption, which reduces the energy consumption of the traditional vacuum system. Before the non-condensable gas is extracted and enters the separation chamber 6, the conical member 7 and the uniform flow plate 8 will guide and uniformly flow the non-condensable gas in advance, and then the equipment will separate the water vapor in the non-condensable gas through the adsorption cotton material 11, and then start the push plate 14 under the telescopic rod 13 to realize the extrusion operation of the adsorption cotton material 11. At the same time, the squeezed water vapor will gather into a fluid and be sent back to the interior of the condenser body 2 through the inclined tube, so that the equipment can achieve the purpose of separating and recovering water vapor and air.
