Abstract

The invention belongs to the energy source circulating reuse field and discloses a boiler flue gas reuse method, which integrates the boiler flue gas use and the clean pulping production improved wood, namely using the fume of the boiler and the cogeneration boiler, through the electro dedust to remove the dust in the fume, as one of the hot wind source of the centrifugal spray drying means to produce the improved wood, realizes the utilization of the fume remaining heat. Meanwhile in the spray drying process, the sulfur dioxide, the nitric oxides in the fume are adsorbed and used in the spray drying means of the improved wood, which advances the quality of the improved wood, purifies the boiler off gas, to make the boiler fume standard discharge develop waste cyclic utilization means, and reduce the pulping paper making and the off gas contamination.

Description

technical field

[0001] The invention belongs to the field of energy recycling and reuse, and in particular relates to a boiler flue gas recycling method. Background technique

[0002] The rapid development of my country's paper industry has attracted worldwide attention. The scale of pulp and paper making has become larger and larger. Pulp and paper companies have boilers with large steam tons and combined heat and power boilers. Encouraging progress has been made in energy saving and emission reduction. However, pulp and paper making is still an energy source. , industries with high resource consumption and serious pollution. After the flue gas of the boiler or combined heat and power boiler has been subjected to electrostatic dust removal, it is difficult to achieve standard discharge. At the same time, the flue gas with a discharge temperature of 150-160°C also contains sulfur dioxide, etc., and the remaining heat and sulfur dioxide cannot be used, resulting in energy wast...
