Square RTO with rotary valve
Rotary RTO, also known as rotary regenerative thermal oxidizer. Its principle is to oxidize the combustible exhaust air into corresponding oxides and water under high temperature, so as to purify the exhaust and recycle the heat released during the decomposition of exhaust air. The decomposition efficiency of exhaust air is over 99.5%, and the heat recycle efficiency is over 97%.
Rotary RTO is mainly composed of combustion chamber, ceramic packing bed and rotary valve. The furnace body is divided into 12 chambers, 5 inlet chambers, 5 outlet chambers, 1 cleaning chamber and 1 isolation chamber. The exhaust gas distribution valve is driven by a motor to rotate continuously and at a uniform speed. Under the action of the distribution valve, the exhaust gas slowly switches continuously between 12 chambers.
