Description

Technical Field

[0001] This utility model relates to the technical field of waste gas denitrification treatment equipment, and in particular to treatment equipment for denitrification of tail gas from waste gas incineration systems. Background Technology

[0002] Waste gas and waste liquid incineration is a high-temperature incineration process. The exhaust gas discharged from the dedicated waste gas and waste liquid incinerator has a high concentration of nitrogen oxides. In order to ensure that the exhaust gas emissions of the final treatment system meet national or local standards and achieve clean production and environmental compliance, it is necessary to denitrify the exhaust gas discharged from the waste gas and waste liquid incinerator. Spraying the waste gas is an important treatment process.

[0003] Existing equipment for denitrification of waste gas first treats the waste gas through a spray assembly before exporting it. Upon export, the gas is filtered again by filter media added to the filter layer inside the outlet. However, as usage time increases, the filter layer absorbs too many impurities from the waste gas and needs replacement. Replacing the filter layer in existing waste gas denitrification equipment requires workers to gradually disassemble the equipment parts and remove the filter layer, which is cumbersome. Therefore, we propose a waste gas incineration system tail gas denitrification treatment device. Utility Model Content
