Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] The present invention provides a miniature bladeless turbine, see attached figure 1 , including: outer sleeve 1, inner sleeve 2, rotor shaft 3, intake nozzle 4, sealing sleeve 5;

[0026] See attached figure 1 , the gas enters between the outer sleeve 1 and the inner sleeve 2 through the air inlet nozzle 4, and drives the inner sleeve 2 to rotate. The inner sleeve 2 is just connected to the rotor shaft 3, and the rotor shaft 3 can perform external work. The gas rotates in the turbine, and as the kinetic energy decreases, the radius of rotation decreases until the gas exits the turbine.

[0027] The sealing sleeve 5 seals the outer sleeve of the air intake end to prevent air leakage at the air intake end.

[0028] See attached figure 2 , is the sectional view of the intake port, the gas enters the turbine from the intake nozzle 4. A microturbin...

Abstract

The invention relates to a blade-free type turbine, and belongs to the technical field of thermal power installations. The blade-free type turbine comprises an internal sleeve, an external sleeve, a rotor spindle, a sealing ring and an air inlet nozzle. The turbine can be used as an acting part of minitype and ultra-minitype combustion gas turbines. A boundary layer principle is used to enable an airflow entering the turbine to drive the internal sleeve and the rotor spindle to rotate, and act outward, and thus the limitation of a blade in the traditional turbine is got rid of. The defects that the requirements of a Tesla turbine on material strength of a disc blade are overhigh and the disc blade is poor in deformation stability in a running process are overcome, meanwhile, the problems that the blade structure of the traditional combustion gas turbine is complex, the manufacturing request is high and the maintenance is difficult are solved, and the novel blade-free type turbine adopting the boundary layer principle is provided.

Description

technical field [0001] The invention belongs to the technical field of thermal power devices, and in particular relates to a miniature bladeless turbine. Background technique [0002] A gas turbine is an internal combustion engine that uses continuously flowing gas as a working medium, and converts the chemical energy of the fuel into mechanical work. Gas turbines are widely used in large power plants, as well as power systems for large machinery. Gas turbines have been widely used in various industrial fields such as aviation, ships, locomotives, electric power, and petroleum. With the development of demand for micro and ultra-micro internal combustion engines, direct miniaturization of traditional heavy-duty and high-power gas turbines cannot avoid problems such as low heat transfer efficiency and difficult blade design. At the same time, gasoline engines and diesel engines also have the problem of low heat transfer efficiency due to the complex cylinder design and canno...
