Description

Technical Field

[0001] The utility model relates to the technical field of RTO incinerators, in particular to a dust blowing device for a heat storage body of an RTO incinerator. Background Art

[0002] The principle of a regenerative incinerator is to oxidize organic matter in exhaust gas into corresponding carbon dioxide and water at high temperatures, thereby purifying the exhaust gas and recovering the heat released during the decomposition of the exhaust gas. The principle is to heat the organic exhaust gas to above 760 degrees Celsius (the specific temperature depends on the composition) so that the VOCs in the exhaust gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a special ceramic thermal storage body, causing the ceramic body to heat up and "storage heat". This "heat storage" is used to preheat the subsequent organic exhaust gas, thereby saving the fuel consumption of exhaust gas heating.

[0003] Currently, existing RTO incinerators use a purge fan to blow air into the chamber for purge. Some impurities attached to the thermal storage element are difficult to be purged. Impurity accumulation can easily cause blockage during long-term use, thus reducing the cleaning effect. To address this issue, we provide an RTO incinerator thermal storage element dust purge device to solve the above problems. Utility Model Content
