The principle of the overall oxygen enrichment effect furnace of the regenerative oxidation furnace is to heat the treatable garbage gas to above 760 ℃, and the overall oxygen enrichment effect of VOC in the garbage gas is decomposed into two overall oxygen enrichment effects, carbon and water. The hot baking gas generated by the overall oxygen enrichment effect flows through the special ceramic heat storage body, so that the ceramic heat storage body is heated to "store heat" for preheating the subsequent treatable garbage gas. Therefore, because the garbage gas is heated, fuel consumption is saved.

The principle of the overall oxygen enrichment effect furnace of the regenerative oxidation furnace is to heat the treatable garbage gas to above 760 ℃, and the overall oxygen enrichment effect of VOC in the garbage gas is decomposed into two overall oxygen enrichment effects, carbon and water. The hot baking gas generated by the overall oxygen enrichment effect flows through the special ceramic heat storage body, so that the ceramic heat storage body is heated to "store heat" for preheating the subsequent treatable garbage gas. Therefore, because the garbage gas is heated, fuel consumption is saved. The ceramic regenerative chamber is divided into two (including two) or more areas or chambers, and each regenerative chamber goes through the process of heat storage, heat release and cleaning in turn. After the "heat release" of the heat exchanger, before the heat exchanger enters the "storage" procedure, clean the heat exchanger by introducing the qualified clean garbage gas (>ensuring that the VOC removal rate is greater than 95%). The main structure of the dual chamber RTO consists of a hot baking integral oxygen enriched effect chamber, two ceramic heat storage chambers and four switch control points. When the treatable garbage gas enters the heat accumulator 1, the heat accumulator 1 releases heat. Heat the treatable garbage gas to about 800 ℃, and then burn it in the hot baking overall oxygen enriched effect chamber. The burning hot baking clean gas passes through the regenerator 2. The heat accumulator 2 absorbs the heat, and the hot baking gas is cooled by the regeneration overall oxygen enriched effect furnace 2 and discharged through the switch control point. After a period of time, open the control point, the treatable garbage gas enters from the heat storage body 2, and the heat storage body 2 releases heat to heat the garbage gas. Garbage gas is burned by the overall oxygen enrichment effect of regenerator 1, and regenerator 1 absorbs heat. The hot baking gas is cooled and discharged through the switch control point. In this way, the treatable garbage gas can be continuously treated without energy consumption or low energy consumption to achieve energy-saving effect. Three chamber RTO is a kind of garbage gas treatment equipment, which is mainly composed of combustion chamber, ceramic packed bed and switch control point. Its principle is to convert the overall oxygen enrichment effect of VOCs treatable garbage gas in hot baking (>760 ℃) into corresponding overall oxygen enrichment effect and water, so as to purify garbage gas and recover the heat released by garbage gas decomposition. The garbage gas purification efficiency is 99%, and the heat recovery efficiency is 95%.
 
Regenerative oxidation furnace is a new type of RTO based on bed RTO structure and promoted through technology iteration. The rotary RTO heat storage integral oxygen enriched effect furnace is set as a circle, and all lifting control points and closing control points are replaced by rotary control points. Rotary RTO is mainly composed of combustion chamber, heat accumulator, rotary control point, etc. Its working principle is to enrich the overall oxygen of VOCs treatable garbage gas into an overall oxygen enriched substance and water under hot baking (760 ℃), so as to purify garbage gas and recover the heat released from its decomposition. The garbage gas purification efficiency reaches 99.5%, and the heat recovery efficiency reaches more than 95%.
 
Can regenerative oxidation furnace treat almost all garbage gases containing treatable compounds? The regenerative integral oxygen enriched effect furnace can handle the treatable garbage gas with high air volume and low concentration, has a large flow elasticity (nominal flow rate 20%~120%), and can adapt to the changes and fluctuations of the treatable garbage gas composition and VOC concentration. It is insensitive to a small amount of dust and solid particles in garbage gas, and its thermal efficiency is higher among all thermal combustion purification methods (>); 95%; Self heating operation without auxiliary fuel is required under proper garbage gas concentration, with high purification efficiency (2 rooms>; 95%, 3 rooms>; 99%, rotating>; 99.5%), small maintenance workload, safe and reliable operation, and regular removal of treatable sediment.
