Abstract

The invention relates to a system for removing varieties of pollutants of fuel gas distribution type energy station and a work method thereof. In the present, control on distribution type energy exhaust pollutants is an important subject to be researched. In the system disclosed by the invention, tail exhaust gas of the distribution type energy system reversely contact a saturated sodium hydroxidesolution or a saturated potassium hydroxide solution which is sprayed from top to bottom, and carbon dioxide and nitric oxide in the exhaust gas is absorbed by saturated sodium (potassium) hydroxide;meanwhile, a contact heat exchange temperature between the exhaust gas and the saturated sodium (potassium) hydroxide solution is reduced, and the purposes of removing varieties of pollutants and reducing the exhaust gas temperature are achieved; in addition, waste absorption liquid is treated to obtain industrial products of sodium (potassium) carbonate and sodium (potassium) carbonate.

Description

technical field [0001] The invention relates to the field of flue gas purification of distributed energy stations, in particular to the technical field of removing various pollutants from flue gas of distributed energy stations. Background technique [0002] Since the combustion of the internal combustion engine adopts the piston compression ignition method, the unit itself cannot achieve low-nitrogen combustion, resulting in a high concentration of NOx emission in the exhaust gas, generally at 200mg / m 3 The above far exceeds the emission requirements of air pollutants, such as the Chinese patent with application number 201710682275.1. In the form of increasingly serious air pollution, it is imminent to reduce the concentration of air pollutant emissions, and NOx emissions are an important indicator of air pollutant emissions. Therefore, reducing the NOx emission mass concentration of the internal combustion engine will also be an important content of the trigeneration syst...
