Flue gas treatment recycling system and recycling method thereof

Abstract

The invention relates to a flue gas treatment recycling system and a recycling method of the flue gas treatment recycling system. The flue gas treatment recycling system comprises a boiler, a desulfurization tower, a purification condenser and a fresh air cooler. An air inlet of the boiler is connected with an air feeder, and a flue gas outlet of the boiler is connected with an inlet of the desulfurization tower. A flue gas side inlet of the purification condenser is connected with an outlet of the desulfurization tower through a pipeline, and a liquid drain outlet of the purification condenser is connected with a condensate water storage tank. A refrigerant side outlet of the fresh air cooler is connected with an inlet of the purification condenser, and a refrigerant side inlet of the fresh air cooler is connected with an outlet of the purification condenser through a circulating pump. An air side inlet of the fresh air cooler is connected with the atmospheric environment, and an airside outlet of the fresh air cooler is connected with the air feeder of the boiler. The invention further comprises the recycling method of the flue gas treatment recycling system. By the adoption ofthe flue gas treatment recycling system and the recycling method of the flue gas treatment recycling system, a large amount of production water is recovered, the boiler efficiency is also improved, and the equipment freezing problem is solved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a flue gas treatment recycling system and a recycling method thereof. Background technique [0002] In the field of waste gas treatment technology, the mainstream of existing technologies at home and abroad is to purify conventional pollutants and unconventional pollutants, which has been widely used. Taking limestone-gypsum wet desulfurization as an example, thermal power generation companies, chemical companies, and metal smelting companies generally adopt limestone-gypsum wet desulfurization technology for flue gas purification. This technology is mature and reliable, and has generally achieved a desulfurization efficiency of over 90%. , Most of the thermal power plants have made the emission concentration of sulfur dioxide reach the ultra-low standard. However, how to recycle the waste gas after environmental protection treatment is still in the research and expe...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems in the prior art that wet desulfurization causes a large amount of water resources to be wasted, and cold source equipment freezes and cannot be used normally due to extreme cold weather, the present invention provides a flue gas treatment recycling system and its recycling method
