Description

Technical Field

[0001] The invention relates to a gas turbine, in particular to a vector gas turbine that can be driven by small-flow steam or high-pressure air, and belongs to the technical field of power machinery. Background Art

[0002] When operating, traditional steam turbines have high requirements for steam flow and pressure. When the steam flow is small or the pressure is low, it is difficult to drive the normal operation of the steam turbine, which limits its application in some scenarios with limited steam resources or unstable steam parameters. For example, in the waste heat recovery system of some small factories, the amount of steam generated is small and cannot meet the operating requirements of traditional steam turbines, resulting in energy waste. In addition, the impellers of traditional steam turbines become larger as they go further back, and the size and structure of each group are different, which makes its structure too complicated, greatly increases the difficulty and cost of manufacturing, and is not conducive to equipment maintenance and overhaul. At present, there is an urgent need for a gas turbine that can adapt to small flow steam or high-pressure air, has a simple structure, and is easy to manufacture, so as to expand the scope of energy utilization and improve energy utilization efficiency. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a vector gas turbine to solve the problems of traditional steam turbines having stringent requirements on steam flow and pressure, as well as complex structure and great manufacturing difficulty, so as to realize the normal operation of the gas turbine by using small flow steam or high-pressure air, while reducing the manufacturing difficulty and cost and improving energy utilization efficiency.

[0004] Technical solution: ◦ The interior of this vector gas turbine consists of a stator and a rotor with directional openings, and one stator and one rotor form a set.

[0005] ◦ The first set of stators has two air guide holes, the second set of stators has four air guide holes, the third set of stators has eight air guide holes, and so on. The number of guide holes in each set of stators increases exponentially. All sets of stators and rotors have the same diameter, and each rotor has the same number of blades. This design avoids the complex structure of different impeller sizes for each set of traditional steam turbines, greatly reduces the difficulty of manufacturing, and facilitates large-scale production and equipment maintenance and replacement.

[0006] ◦ The airflow direction of the stator's airflow guide hole is basically perpendicular to the plane of the rotor blade, and the rotor blade and the air guide hole are as close to the outer side of the circumference as possible. This design allows the guided airflow to generate maximum torque on the rotor blade, and more effectively convert the energy of the airflow into the rotational mechanical energy of the rotor.

[0007] ◦ The main shaft of the gas turbine is designed to be placed vertically, and the airflow pushes the rotor blades from bottom to top. The upward thrust of the high-pressure airflow and the gravity of the rotor offset each other, forming a suspended rotation, which greatly reduces the rotational friction of the rotor and thus improves the mechanical energy conversion efficiency.

[0008] Beneficial effects: ◦ It can adapt to the working conditions of small flow steam or high-pressure air, expanding the application scope of gas turbines and making effective use of some energy that was originally unusable due to insufficient steam flow or pressure, such as waste heat steam from small factories and high-pressure air released by compressed air energy storage systems.

[0009] ◦ The unique stator guide hole design and rotor blade layout enable the airflow to generate maximum torque on the rotor blades, improving the energy conversion efficiency. Compared with traditional gas turbines, it can output greater power under the same airflow conditions.

[0010] ◦ The main shaft is placed vertically and the design of using airflow thrust and gravity to offset the floating rotation effectively reduces the friction of the rotor rotation, reduces energy loss, further improves the mechanical energy conversion efficiency, and reduces equipment wear and extends the service life of the equipment.

[0011] ◦ The design of the same stator and rotor diameter and the same number of blades significantly reduces the manufacturing difficulty, reduces the process complexity and precision requirements in the production process, thereby reducing manufacturing costs and improving the market competitiveness of the product.
