Description

Technical Field

[0001] The utility model relates to the technical field of turbine units, in particular to an energy recovery power generation turbine unit that can be used for multiple media. Background Art

[0002] A turbine, also known as a turbine or turbomachine, is a machine that converts the energy contained in a fluid medium into mechanical energy and vice versa. Turbines vary in their operating conditions and working fluids, resulting in a variety of structural types, but their basic operating principles are similar. The most important component of a turbine is a rotating element, the rotor, or impeller, mounted on the turbine shaft and equipped with blades evenly spaced along its circumference. The energy of the fluid is converted into kinetic energy as it flows through the nozzle. As it flows through the impeller, the fluid impacts the blades, driving the impeller and thus rotating the turbine shaft. The turbine shaft drives other machinery, either directly or through a transmission mechanism, to produce mechanical work. The working fluid of a turbine can be a gas, such as steam, gas, air, or other gases or mixtures, or a liquid, such as water, oil, or other liquids. Turbines using water as the working fluid are called water turbines; turbines using steam as the working fluid are called steam turbines; and turbines using gas as the working fluid are called gas turbines.

[0003] A turbine unit generally consists of a stator assembly and a rotor assembly. The stator assembly is provided with a liquid inlet and a liquid outlet, while the rotor assembly includes a turbine shaft and an impeller mounted on the turbine shaft. For example, liquid enters the stator assembly through the liquid inlet and then exits through the liquid outlet. During this process, the liquid impacts the impeller on the rotor assembly, causing the impeller to rotate the turbine shaft, generating mechanical energy. When the turbine shaft is connected to a generator, this mechanical energy can be converted into electrical energy. As can be seen from the above, a single turbine unit can only convert the energy contained in a single medium. If multiple media need to be converted, the operation method of passing multiple media through the turbine unit sequentially is time-consuming, labor-intensive, and cumbersome. If multiple turbine units are added to accommodate the various media, the company must purchase multiple turbine units, increasing production costs and requiring significant maintenance expenses.

[0004] In view of the inconveniences of the above two methods, we propose an energy recovery power generation turbine unit that can be used for multiple media to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to solve the problems in the prior art and to propose an energy recovery power generation turbine unit that can be used for multiple media. The turbine unit has multiple closed chambers that do not interfere with each other. Each closed chamber has an impeller. The closed chamber and the impeller inside it constitute a working chamber. Then, the multiple working chambers can respectively receive multiple media at the same time to work together to rotate the turbine shaft. The multiple media do not interfere with each other and are easy to use.

[0006] In order to solve the above problems, the present invention provides the following technical solutions:

[0007] A multi-media energy recovery power generation turbine unit includes a stator assembly and a rotor assembly rotatably disposed on the stator assembly. The stator assembly has at least two mutually non-interfering sealed chambers, and each sealed chamber is provided with an inlet and an outlet. The turbine shaft on the rotor assembly is dynamically sealed and passes through the multiple sealed chambers. An impeller is disposed on the turbine shaft in each sealed chamber so that when each impeller is acted upon by a corresponding medium, the multiple impellers rotate in the same direction and together drive the turbine shaft to rotate.

[0008] As a further solution of the present invention: the stator assembly has a cavity inside, and at least one partition is sealed in the cavity to divide the cavity into at least two closed chambers, and the turbine shaft dynamic seal on the rotor assembly penetrates the partition.

[0009] As a further solution of the present invention: dynamic sealing is achieved between the turbine shaft and the partition plate through a mechanical seal.

[0010] As a further solution of the present invention: the turbine unit also includes a protective component for protecting the mechanical seal, the protective component includes a baffle arranged on one side of the partition, and the baffle is sleeved on the outside of the turbine shaft, and a protective cover is provided on the side of the baffle facing the partition, and the protective cover is used to cover one end of the mechanical seal.

[0011] As a further solution of the present invention: the protective cover is configured as a truncated cone as a whole, and the large diameter end of the protective cover faces the mechanical seal.

[0012] As a further solution of the present invention: a connecting rod is fixedly provided on the partition, and the baffle is fixedly provided on the connecting rod.

[0013] As a further solution of the present invention: the turbine shaft and the frustum-shaped protective cover are coaxially arranged.

[0014] As a further solution of the present invention: each impeller is installed in the same direction as the turbine shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up at least two closed chambers, the turbine shaft passes through the multiple closed chambers in sequence, and the turbine shaft is provided with an impeller inside each closed chamber. The closed chamber and the impeller inside it constitute a working chamber. Then, the multiple working chambers can respectively receive multiple media at the same time, which are used to work together to rotate the turbine shaft. The multiple media do not interfere with each other, and are easy to use.

[0017] 2. By setting up the protective component, the mechanical seal between the turbine shaft and the partition can be protected by the protective component to prevent the medium flowing inside the closed chamber from causing impact damage to the mechanical seal, thereby ensuring the stability of the dynamic seal cooperation between the partition and the turbine shaft.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1-4As shown, a multi-media energy recovery power generation turbine unit includes a stator assembly 1 and a rotor assembly 2. The stator assembly 1 has a cavity within it, and at least one partition 3 is sealed within the cavity to divide the cavity into at least two sealed chambers 101. Each sealed chamber 101 is provided with an inlet for medium entry and an outlet for medium exit. The rotor assembly 2 has a turbine shaft 201, which is rotatably mounted on the stator assembly 1 and sequentially penetrates multiple partitions 3 and extends into the sealed chambers 101. It should be noted that the turbine shaft 201 and the partitions 3 are dynamically sealed to ensure that the sealed chambers 101 remain sealed after the turbine shaft 201 penetrates. An impeller 202 is disposed within each sealed chamber 101 on the turbine shaft 201. The impeller 202 is coaxial with the turbine shaft 201 and each impeller 202 is installed in the same direction.

[0026] There is no limit to the number of partitions 3 in this article, and it can be set according to actual work needs; Figure 1 The figure shows a case where a partition 3 is installed to form two sealed chambers 101. Under this configuration, when using the turbine unit to simultaneously process two media, the two media can be allowed to enter the two sealed chambers 101 separately. The media will impact the impellers 202 within the corresponding sealed chambers 101, causing the impellers 202 to rotate. Because the two impellers 202 are installed in the same direction and have the same rotation direction, they can jointly drive the turbine shaft 201 to rotate. By connecting the turbine shaft 201 to other energy-demanding components, energy conversion can be achieved. For example, by connecting the turbine shaft 201 to the rotating shaft of a generator via a coupling, the mechanical energy generated by the turbine shaft 201 can be converted into electrical energy.

[0027] It should be noted that the stator assembly 1 and the rotor assembly 2 in the present invention are both conventional technical means in the prior art. The stator assembly 1 is used as a carrier for the medium to enter and flow out, and the rotor assembly 2 is used to transfer and convert the energy of the medium. In some possible embodiments, the stator assembly 1 is set as a pump body or its derivatives, and the rotor assembly 2 is set as a combination of a turbine shaft 201 and an impeller 202 or its derivatives.

[0028] like Figure 2-Figure 3 As shown, the dynamic sealing setting between the turbine shaft 201 and the partition 3 can be achieved by a conventional mechanical seal 4; in order to ensure that the medium inside the sealing chamber 101 does not cause a large impact on the mechanical seal 4, the utility model is provided with a protective component for protecting the mechanical seal 4.

[0029] Specifically, the protection assembly includes a connecting rod 7 fixedly arranged on the side of the partition 3, a baffle 5 is provided on the connecting rod 7, and the baffle 5 is sleeved on the outside of the turbine shaft 201. The baffle 5 does not interfere with the rotation of the turbine shaft 201. A protective cover 6 is provided on the side of the baffle 5 facing the partition 3. The protective cover 6 is used to cover one end of the mechanical seal 4. This state is as shown in FIG. Figure 2 As shown, in this state, when the medium inside the sealed chamber flows, it will first be blocked by the baffle 5, thereby weakening the impact of the medium on the mechanical seal 4, protecting the mechanical seal 4, and ensuring the sealing between the two adjacent sealed chambers 101. Of course, to improve the protection effect, protective components can be provided on both sides of the partition 3, and then two sets of protective components can respectively protect the two ends of the mechanical seal 4.

[0030] like Figure 2 and Figure 4 As shown, on the basis of setting up the protection component, in order to make the protective cover 6 have a better covering effect on the mechanical seal 4, the present embodiment can set the protective cover 6 as a whole to be a truncated cone, and the large diameter end of the protective cover 6 faces the mechanical seal 4. At the same time, the turbine shaft 201 is coaxially arranged with the truncated cone-shaped protective cover 6, and the mechanical seal 4 is completely covered by the large diameter opening end of the protective cover 6.

[0031] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
