Problems solved by technology

[0010] Therefore, ozone and NO X The mixing effect and speed have a very important impact on the denitrification efficiency. The injection device currently used is composed of a main pipe and multiple nozzles. The nozzles are in contact with the flue gas flow for a long time, which makes the nozzles particularly easy to wear and tear. The mixing effect is not good; the flat swirl plate is used to hinder the gas flow and affect the work efficiency

Abstract

The invention belongs to the technical field of ozone denitrification, and in particular relates to an injection mixing device for ozone denitrification. The mixing device comprises a reaction pipeline and an injection device connected with an ozone generator, an ozone main pipe is arranged in the described reaction pipeline, and the several injection devices are arranged on the side wall of the ozone main pipe; the injection device consists of a main injection pipe and an injection branch pipe Composition, the injection branch pipe is provided with nozzles; the injection main pipe and the two injection branch pipes are Y-shaped, and the injection main pipe is connected with the ozone main pipe; Direction; the injection main pipe and the injection branch pipe are all arranged in the protective cover; the spiral swirl plate is arranged in the reaction pipeline; the ozone main pipe can rotate under the action of the motor. The mixing device has the advantages of simple structure, fast flue gas velocity, good mixing effect between the nozzle and the original flue gas, high working efficiency and long service life.

Description

technical field [0001] The patent of the invention belongs to the technical field of ozone denitrification, and specifically relates to an ozone denitrification injection mixing device. Background technique [0002] With NO X The increasing emissions from NO X The resulting environmental pollution has attracted increasing attention. Due to the fuel characteristics of waste incinerators and biomass fuel boilers, the composition of flue gas, and the properties of fly ash, conventional SCR and SNCR methods cannot be used for flue gas denitrification. [0003] At present, the two mainstream solutions are low-temperature SCR and ozone oxidation denitrification technology. In terms of technical and economical comparison, ozone oxidation denitrification has great advantages. Ozone oxidation denitrification mainly uses the strong oxidizing properties of ozone to reduce flue gas NO X The insoluble NO, which accounts for more than 95% in the environment, is converted into soluble...
