Problems solved by technology

In a thermal power plant or a nuclear power plant, the steam is used to drive the steam turbine to rotate, so as to convert heat energy into mechanical energy and then further into electrical energy. After the steam drives the steam turbine to rotate, there will still be some steam that needs to be condensed with cooling water. After the steam is condensed into water, it is recycled. In the process of condensing the steam into water, the closed cooling tower

Abstract

The invention discloses an auxiliary cooling device for a steam turbine. The auxiliary cooling device comprises a cooling box. The upper portion of the cooling box fixedly communicates with a steam inlet. The side faces and the upper surface of the cooling box are each fixedly provided with cooling fins. The bottom end of the steam inlet communicates with a steam channel. The steam channel is fixedly arranged in the cooling box. A blade grid is arranged in the steam channel. A rotary shaft penetrates the cooling box and is rotationally connected with the cooling box. The middle portion of the rotary shaft is fixedly connected with the blade grid. The two ends of the rotary shaft are each fixedly provided with a fan. A cooling water pipe fixedly penetrates the bottom of the cooling box. The bottom of the cooling box fixedly communicates with a condensate water outlet. The auxiliary cooling device is reasonable in design; and by means of a series of structures, waste heat of steam in the steam engine can be utilized for driving the fans to cool the steam, and therefore under the condition of achieving the same cooling effect, more energy is saved, and high practicality is achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial machinery, and in particular relates to an auxiliary cooling device for a steam turbine. Background technique [0002] A steam turbine is a rotary power machine that converts steam energy into mechanical work, also known as a steam turbine. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. Use the exhaust steam or intermediate steam extraction of the steam turbine to meet the heating needs of production and life. In a thermal power plant or a nuclear power plant, the steam is used to drive the steam turbine to rotate, so as to convert heat energy into mechanical energy and then further into electrical energy. After the steam drives the steam turbine to rotate, there will still be some steam that needs to be condensed with cooling water. After the steam is condensed into water, it is recycled. In the proces...
