RTO Thermal Storage Incineration System

The working principle of RTO regenerative incineration system:

The principle is to heat the organic waste gas to around 820 degrees Celsius, so that the VOCs in the waste gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and "store heat", which is used to preheat the organic waste gas that enters later. Thus saving fuel consumption for exhaust gas heating. Treat VOC exhaust gas through the following actions. Cycle, the exhaust gas enters chamber 1, the heat storage body releases heat, the exhaust gas heats up, and is discharged from chamber 2. The heat storage body stores heat, and the exhaust gas cools down. In the second cycle, by switching the valve, the exhaust gas enters the second chamber, the heat storage body releases heat, the exhaust gas heats up, and is discharged from chamber 1. The heat storage body stores heat, and the exhaust gas cools down. In this way, by switching the valve, the intake and exhaust are switched, and the processed gas is directly heated or cooled by the heat storage body, thereby achieving higher thermal efficiency.

The RTO regenerative incineration system is generally divided into: rotary RTO, two chamber RTO, three chamber RTO, rotary condensing and oxidizing RTO (RCO)

Characteristics of rotary RTO:

The rotary RTO furnace uses ten (numbered 1~10 #) fixed heat exchange medium beds, and the heat exchange medium is thermal storage ceramics. The exhaust gas from the production line is heated after passing through four (numbered 1~4 # as the inlet area) thermal ceramic medium beds; The high-temperature gas burned after entering the furnace heats up the other four (6-9 # are exhaust areas) heat exchange medium beds, while the corresponding 5 # and 10 # beds are purge areas. Under the action of the rotary switching valve, the two sets of numbers of the ceramic medium beds change cyclically (such as 2-5 # are intake areas, 7-10 # are exhaust areas, 6 # and 1 # beds are purge areas, and so on). In this way, the two sets of heat exchange medium beds switch to each other, store heat and heat the low-temperature exhaust gas. Since only 25% of the ceramic medium changes the direction of the airflow each time, it effectively reduces the wind pressure fluctuation at the RTO inlet and outlet, has little impact on the pressure of the front-end production line, and is more suitable for coating lines. Moreover, due to the internal design of the switching valve, the purge air duct is used to heat the low-temperature exhaust gas. Therefore, the decomposition rate is higher than that of tower RTO, achieving a decomposition rate of over 99% for organic waste gas and ultimately meeting national environmental standards for waste gas emissions. The heat exchange efficiency reaches over 95%. If the concentration of organic waste gas is sufficient, it is easy to achieve self maintenance of the oxidation furnace without using any fuel.
