Air Pollution Control

Intelligent Control System of Flue Gas Environmental Protection Island of Coal-fired Power Station

Relying on cutting-edge technical means such as artificial intelligence and big data, Longking smart environmental protection deeply excavates the operation data characteristics and potential laws of environmental protection equipment, integrates the knowledge system of industry experts, and forms an industrial level intelligent emission control and intelligent equipment operation and maintenance scheme. At present, it has been successfully applied to dozens of projects such as Huaneng Yuhuan Power Plant, Huadian Liuan Power Plant and Guoneng Jiujiang Power Plant, and achieved significant carbon reduction benefits. The intelligent environmental protection island optimization control system has won the "Industrial Internet Application and Best Practice Application Award of 2019".

Intelligent Dust Removal: saving energy consumption more than 1.6 million yuan per year and reducing carbon emission of 3500 + tons

Intelligent desulfurization: the material consumption cost is saved by over 700 thousand yuan per year and the carbon emission is reduced by over 2000 tons

Intelligent denitration: the ammonia escape rate is reduced by 10%, and the cost of denitration agent is reduced by 300+ thousand yuan
