Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment equipment, and specifically relates to a heat storage type high temperature oxidation waste gas treatment device. Background Art

[0002] The regenerative thermal incinerator is also called the regenerative oxidizer. The principle of the regenerative oxidizer is to heat the exhaust gas to a temperature close to the thermal oxidation temperature through a regenerative body, and then enter the combustion chamber for thermal oxidation. The temperature of the oxidized gas increases, and the organic matter is basically converted into carbon dioxide and water. The purified gas passes through another regenerative body, and the temperature drops. It can be discharged after meeting the emission standards. Different regenerative bodies are converted over time through switching valves or rotating devices to absorb and release heat respectively.

[0003] After the existing thermal storage oxidation furnace mixes the gas with the hot gas, the hot gas is absorbed by the heat storage box so as to continuously heat the gas to be circulated later, thereby achieving energy-saving effects. However, after the existing heat storage box absorbs heat energy, the temperature inside the box continues to increase, which will lead to a decrease in heat exchange efficiency, because the high temperature makes it difficult for the heat in the exhaust gas to be effectively absorbed and utilized, thereby reducing the heat energy recovery efficiency. When the heat storage box has insufficient waste heat, the temperature inside the box continues to decrease, and the subsequently heated gas cannot meet the heating conditions, resulting in uneven gas mixing and impure gas purification.
