Problems solved by technology

[0004] In the above public documents, during the gas treatment process, the soot particles in the gas cannot be removed, resulting in insufficient denitrification of the gas during the denitrification process; on the other hand, the time of the gas in the denitrification tower is relatively short, and There is a denitration agent spraying device on one side of the board, which makes the gas reaction not sufficient, low working efficiency and poor effect

Description

technical field [0001] The invention relates to the technical field of flue gas denitration, in particular to a flue gas denitration device for solid waste treatment. Background technique [0002] In the treatment of solid waste, the pulverized solid material is usually burned and cracked by a rotary kiln to decompose it into water, oil and gas. However, the generated waste gas needs to be treated and can be discharged only after reaching the national emission standard. [0003] The Chinese patent publication number CN213221597U discloses a flue gas denitrification device for a solid waste treatment system. The solid waste treatment system includes a rotary kiln, a secondary combustion chamber and a quenching tower connected in sequence. A flue gas denitrification tower is connected in series between them. The flue gas denitrification tower includes a tower body, a urea distribution mechanism and an atomizing spray gun. The reaction chamber and the cooling chamber are conn...
