Cooling structure of turbine outer shell flange based on micro-electronics technology

Abstract

The invention discloses a cooling structure of a turbine outer shell flange based on a micro-electronics technology. The cooling structure comprises a turbine outer shell, the turbine outer shell is internally provided with a turbine space which the left end wall communicates with the outside space, and a constant-pressure water storage space which the upper end wall communicates with the turbinespace is formed in the right inner side of the lower end wall of the turbine space; and a cooling space is formed in the right inner end wall of the constant-pressure water storage space, an exhaust pipeline which the right end wall communicates with the outside space is arranged in the lower inner side of the right end of the cooling space, and a translation space which the lower end wall communicates with a steam pipeline is formed in the right inner end wall of the turbine space. According to the structure, when in use, the device has the advantages that the mechanism is simple, the operation is convenient, and the flange of the turbine outer shell can be continuously cooled, moreover, the equipment can be rapidly cooled after the working is stopped, the possibility of steam leakage isreduced, and the residual problem of the steam tail gas residual can be well treated; and the problem of condensation inside the equipment is solved, the energy generated by the equipment is reasonably utilized, so that the energy loss is effectively reduced, and then the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of steam turbine cooling, in particular to a cooling structure for a flange of a casing of a steam turbine based on microelectronic technology. Background technique [0002] At present, with the advancement of science and technology and the development of society, steam turbines are used more and more widely, and the demand for steam turbines is increasing. The cooling capacity of the existing steam turbine casing is poor, and it is difficult to cool down quickly after the equipment stops, and it is easy to generate steam. Leakage, often condensed water inside the equipment is difficult to deal with, and the exhaust gas capacity of the equipment is wasted, resulting in energy waste and low work efficiency. Contents of the invention [0003] The object of the present invention is to provide a cooling structure for the casing flange of a steam turbine based on microelectronic technology, so as to solve the problems ra...
