Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a purification treatment device for reducing RTO nitrogen oxide emissions. Background Art

[0002] RTO is an air pollution control equipment used to treat organic waste gas and volatile organic compounds. It is mainly used for the efficient purification of organic waste gas emitted in industrial production processes. By introducing organic waste gas into a high-temperature furnace, it reacts with oxygen under high temperature conditions to oxidize and decompose harmful substances in the organic waste gas into harmless carbon dioxide and water.

[0003] In existing RTO systems, there is usually no pre-purification treatment device in front of them. Therefore, when the concentration of nitrogen oxides in the exhaust gas is high, even if the RTO system operates normally, it may not be able to completely oxidize it into harmless substances, resulting in increased emissions and causing environmental pollution. Therefore, technical personnel in this field provide a purification treatment device for reducing RTO nitrogen oxide emissions to solve the problems raised in the above background technology.
