Energy-saving environmental-friendly gas turbine

Abstract

The invention relates to the technical field of power equipment and discloses an energy-saving environmental-friendly gas turbine. The energy-saving environmental-friendly gas turbine comprises a body. A containing platform is fixedly connected to the bottom end in the body. A fuel gas working unit is fixedly connected to the top end of the containing platform. A first connecting pipe is fixedly connected to one end of the fuel gas working unit. A recycling box is fixedly connected to the end, away from the body, of the first connecting pipe. A thermal insulating layer is fixedly connected to the inner wall of the recycling box. A recycling cavity is formed in the inner side of the thermal insulating layer. A water injection opening is fixedly connected to one side of the top end of the recycling box. A first heat exchanger is fixedly connected to the bottom end of the water injection opening. A heating pipe is fixedly connected to the bottom end of the first heat exchanger. According to the energy-saving environmental-friendly gas turbine, by arranging the first heat exchanger and a second heat exchanger, the first heat exchanger is filled with cold water, when high-temperature exhaust passes the recycling cavity, the heat of the exhaust is absorbed by the cold water and the exhaust is cooled, meanwhile the temperature of the cold water rises due to the heat of the exhaust, and the water flows out of a water outlet and is used for other processes.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an energy-saving and environment-friendly gas turbine. Background technique [0002] Existing exhaust gas exhausted by gas turbines generally has a temperature between 400°C and 600°C, and the heat taken away by the exhaust gas accounts for about 35%-50% of the calorific value of the fuel. There are currently two main ways to recover the waste heat of exhaust exhaust exhausted by gas turbines: 1. Direct heat exchange, that is, use exhaust gas to heat cold water into hot water and use exhaust gas to heat users. The advantage of this method is that the method is simple and direct to use; 2. The Rankine cycle power generation system is used for power generation. The advantages of this method The recycling rate is high, but the power machines it uses are all steam turbines or turbines, which have high requirements for the quality of steam produced by heat exchange, and the in...
