Problems solved by technology

[0004] The existing desulfurization and denitrification technology is difficult to meet the increasing flue gas emissions. With the rapid economic development, environmental pollution is also spreading rapidly. Therefore, in order to improve the efficiency of desulfurization and denitrification, a new type of combined desulfurization is needed. Denitrification devices are used to strengthen the deficiencies of existing technologies, and at the same time improve the combined desulfurization and denitrification process to provide a good impetus and guidance for the development of comprehensive flue gas treatment technology in the future

Abstract

The invention discloses a combined desulfurization and denitrification device and process, which mainly includes a dust removal system, a desulfurization and denitrification tower, an ammonia water tank, and an ozone tank; Gas port, the interior of the desulfurization and denitrification tower is divided into a desulfurization section and a denitration section from bottom to top; the dust removal system is connected to the smoke inlet; the desulfurization section includes a spray ball, a flue gas dispersion ring, and an oxidation pool; The denitration section includes a mixer and a denitration packing layer. The combined desulfurization and denitrification device and process of the present invention, through the structural design of the combined multi-stage desulfurization and denitrification device, has high desulfurization and denitrification efficiency and good use effect.

Description

technical field [0001] The invention relates to the technical field of desulfurization and denitrification, in particular to a combined desulfurization and denitrification device and process. Background technique [0002] According to literature records, with the rapid development of my country's economy, the emissions are also increasing. The release of coal combustion accounts for 85% of the total emissions, accounting for 60% of the total emissions, and the acid rain caused by the two accounts for 82% of the total acid rain. According to relevant studies, the economic loss caused by my country's annual discharge is about 100 million yuan, and the annual economic loss caused by acid rain pollution in my country is about 500 billion yuan. [0003] Since the 1970s, developed countries have experienced flue gas SO 2 Based on the research on emission control technology, the research on the neutralization and simultaneous removal of industrial flue gas began. Most of the des...
