AI Technical Summary

Technical Problem

Existing flue gas denitrification equipment is expensive and prone to corrosion, requires frequent maintenance, suffers from scaling which affects the equipment, and reduces efficiency if the reaction temperature is not up to standard, making it difficult to efficiently treat NOx in flue gas.

Method used

Design an absorption device that includes an agitation tank, a clarification tank, a heat exchanger, and a water pump system. Utilize waste heat from flue gas to heat the agitation tank, and combine this with hot water from the clarification tank to clean the inner wall, thereby achieving rapid sedimentation and chemical reaction.

Benefits of technology

Waste heat is used to accelerate the chemical reaction, improve denitrification efficiency, and hot water is used to clean the inner wall to prevent scaling, extend equipment life, and improve processing efficiency.
