Gas turbine intake air treatment method integrating pollutant cleaning, filtration and evaporative cooling

Abstract

The invention discloses a gas turbine intake air treatment method integrating pollutant cleaning, filtration and evaporative cooling, which belongs to the field of energy technology and includes intake air filtration, runner dehumidification, evaporative cooling, intake air cleaning, water removal and water regeneration Five steps, clean the intake air of the gas turbine, remove dust, remove haze, remove gas pollutants and evaporative cooling, spray cooling water into the dry air dehumidified by the dehumidification wheel, remove dust and haze particles and the existing filtration system cannot filter cleared SO 2 , NO x Gas pollutants that are soluble in water or can chemically react with water can reduce the intake air temperature through water evaporation and absorb heat, achieving the integrated effect of cooling and cleaning the intake air.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a gas turbine intake air treatment method integrating pollutant cleaning, filtering and evaporative cooling. Background technique [0002] At present, the method of cleaning pollutants from gas turbine intake air has not been involved in domestic and foreign patent documents. Just as the steam cycle generator set has certain requirements for the quality of its working medium (water or steam), and water treatment is required, the gas turbine also needs to clean and filter its working medium (air). Existing gas turbine air intake filtration systems can only filter solid and liquid pollutant particles but cannot remove gas pollutants, but SO 2 and NO x Such corrosive gases entering the gas turbine will cause corrosion, fouling and other adverse effects on the equipment, and even threaten the operation safety of the combined cycle unit. Such gaseous pollutants should be removed by...

Problems solved by technology

Since the exhaust heat of the gas turbine is used to concentrate and regenerate the solution of the solution dehumidifier instead of generating steam to expand and do work in the steam turbine, although the output of the gas turbine has increased, it has reduced the output of the steam turbine and the total cycle time On the contrary, the output decreased

At the same time, from using the gas turbine exhaust waste heat to generate hot water, to using hot water to concentrate and regenerate the solution dehumidifier, it involves multiple energy conversions, as well as heat dissipation and heat preservation of hot water pipes, so the energy utilization rate is relatively low

[0009] Similarly, there is no evaporative cooling and cleaning device in this patent document, and the intake air is not cleaned to remove dust, haze, and gas pollutants.
