Abstract

The invention discloses an axial-flow turbine for a 2MW ORC waste heat utilization system, and relates to the technical field of low-temperature waste heat recovery ORC turbines. The invention aims to solve the problem that an existing radial flow type turbine technology cannot be suitable for a large-capacity ORC low-temperature waste heat power generation system. The adjusting end of a turbine air cylinder is connected to a front bearing box, and the electric end of the turbine air cylinder is connected to a rear bearing box; the turbine rotor is horizontally arranged, the front end of the turbine rotor is installed in the front bearing box, the rear end of the turbine rotor is installed in the rear bearing box, a front end shaft seal is arranged between the front end of the turbine air cylinder and the turbine rotor, a rear end shaft seal is arranged between the rear end of the turbine air cylinder and the turbine rotor, and the stator blade assembly is installed on the inner side wall of the turbine air cylinder. The moving blade assembly is installed on the outer side wall of the turbine rotor, the moving blade assembly on the outer side wall of the turbine rotor is matched with the static blade assembly in the turbine air cylinder, and the front bearing box and the rear bearing box are both supported on the base frame. The low-temperature waste heat is mainly used for power generation.

Description

technical field [0001] The invention relates to the technical field of low-temperature waste heat recovery ORC turbines, in particular to an axial-flow turbine used in a 2MW ORC waste heat utilization system. Background technique [0002] In terms of ORC low-temperature waste heat power generation system, there are still some technical defects and technical shortcomings in my country. At present, the relatively mature technology in China is the radial flow ORC system, but the existing radial flow ORC system can only achieve a capacity of several hundred kW. , it cannot be applied to the large-capacity ORC low-temperature waste heat power generation system. SUMMARY OF THE INVENTION [0003] The technical problems to be solved by the present invention are: the existing radial turbine technology cannot be applied to a large-capacity ORC low temperature waste heat power generation system; furthermore, an axial flow turbine for a 2MW ORC waste heat utilization system is provided...
