Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, and more specifically, to a rotary heat storage waste gas purification oxidation furnace. Background Art

[0002] The regenerative thermal incinerator is also called: regenerative oxidizer, referred to as "RTO". Its principle is to heat the organic waste gas to above 760 degrees Celsius, so that the VOC in the waste gas is oxidized and decomposed into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a special ceramic heat storage body, causing the ceramic body to heat up and "storage heat". This "heat storage" is used to preheat the organic waste gas that enters later. Thereby saving fuel consumption for heating the waste gas. The ceramic heat storage body should be divided into two (including two) or more areas or chambers, and each heat storage chamber will go through the procedures of heat storage-heat release-cleaning in turn, over and over again, and work continuously. After the heat storage chamber "releases heat", part of the clean exhaust gas that has been treated and qualified should be immediately introduced to clean the heat storage chamber to ensure that the VOC removal rate is above 95%. Only after the cleaning is completed can the "heat storage" procedure be entered.

[0003] The combustion chamber of the existing regenerative thermal oxidation furnace is an open design inside the oxidation furnace. When the combustion chamber burns and oxidizes the exhaust gas for a long time, it is easy to produce a lot of sediment attached to the ceramic heat storage body. As time accumulates, the sediment attached to the ceramic heat storage body will become thicker and thicker, affecting the heat storage effect of the ceramic body, causing the exhaust gas treatment efficiency to become low, and the fine sediment discharged into the air will also cause environmental pollution. Therefore, there is room for improvement in this device.

[0004] In view of this, research and improvement are carried out on the existing problems, and a rotary heat storage exhaust gas purification oxidation furnace is provided, aiming to achieve the purpose of solving the problems and improving the practical value through this technology.
