Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a skid-mounted RTO. Background Art

[0002] The basic principle of RTO is to oxidize organic waste gas to produce CO2 and H2O at high temperature (≥760℃), thereby purifying the waste gas and recovering the heat released during decomposition to achieve the dual goals of environmental protection and energy saving. It is an energy-saving and environmentally friendly device used to treat medium and high concentration volatile organic waste gas.

[0003] The traditional three-tower RTO system has three states. RTO has three towers. In state 1, tower 1 of RTO is intake, tower 2 is exhaust, and tower 3 is backflushing. In state 2, tower 1 of RTO is backflushing, tower 2 is intake, and tower 3 is exhaust. In state 3, tower 1 of RTO is exhaust, tower 2 is backflushing, and tower 3 is intake. States 1, 2, and 3 are switched in sequence.

[0004] The purpose of backflushing is to blow the exhaust gas remaining in the middle of Tower 1 when switching from Stage 1 to Stage 2 back to the front end of the RTO for further treatment. However, due to the existence of airflow dead corners in the air cavity at the bottom of the RTO, the backflushing effect is limited. Furthermore, the traditional three-tower RTO system places multiple valves side by side, which takes up space and is not conducive to transportation. Utility Model Content
