Abstract

The invention relates to device for achieving flue gas power generation and removing harmful substance in flue gas simultaneously. The device comprises a flue gas treatment system, a transduction system and an electric generator; the flue gas treatment system is composed of a shell, an evaporative condenser, a flue gas inlet and a flue gas outlet; the transduction system comprises a working medium evaporator, a working medium turbine, a condenser and a working medium compressor which are sequentially connected; the output end of the working medium compressor and the input end of the working medium evaporator are connected with a working medium outlet and a working medium inlet of a heat exchanger respectively; the working medium turbine drives the electric generator. According to the device for achieving flue gas power generation and removing harmful substance in the flue gas simultaneously, heat in flue gas is utilized to conduct heating, so that an organic working medium is evaporated, the working medium turbine is pushed to generate power, the heat utilization rate is high, and meanwhile harmful substances in the flue gas can be removed.

Description

technical field [0001] The invention relates to a device for generating electricity with flue gas while removing harmful substances in the flue gas, and belongs to the technical field of gas pollution control. Background technique [0002] The flue gas produced by industrial furnaces has a high temperature, contains a large amount of water vapor, and has a high energy value. The existing technology adopts a heat exchange device in the flue gas channel, using the heat in the flue gas to heat water to form a hot water cycle, and the hot water further heats the organic working medium, so that the organic working medium evaporates and drives the steam turbine to generate electricity. Pollutants and harmful gases are the main pollutants of air pollution, causing important air pollution phenomena such as smog and acid rain. In the prior art, the harmful substances in the flue gas cannot be removed, the temperature of the flue gas must be controlled above the dew point of the flue...
