Description

Technical Field

[0001] This application relates to the technical field of waste gas heat recovery, and in particular to a rotary RTO. Background Art

[0002] A rotary RTO, namely a rotary regenerative thermal oxidizer, the core component of the rotary RTO is a rotary valve with multiple regenerative chambers. Waste gas enters one of the regenerative chambers through the intake pipe and is preheated to near the combustion temperature. Then, the high-temperature waste gas enters the combustion chamber, mixes with fuel in the combustion chamber and burns, oxidizing and decomposing the organic matter in the waste gas into harmless substances such as carbon dioxide and water. The high-temperature gas after combustion then enters another regenerative chamber, transfers heat to the regenerator, and is discharged after its own temperature drops. At the same time, the rotary valve rotates continuously, enabling each regenerative chamber to successively perform processes such as intake, preheating, combustion, and exhaust, realizing continuous operation.

[0003] However, the existing rotary RTO may lack an effective interception structure for larger particulate pollutants, resulting in larger particles entering the subsequent treatment process, affecting the waste gas treatment effect, increasing the burden on subsequent treatment equipment, shortening the service life of the equipment, and there is no design for conveniently removing impurity pollutants, which is prone to impurity accumulation, increasing the risk of secondary pollution to the environment. Moreover, for the existing rotary RTO, it is mostly inconvenient to place tools during maintenance. Usually, there is no slidable tool box structure. When operators inspect, maintain, and repair the equipment, they need to run back and forth to find tools, wasting time and reducing work efficiency.
