And the middle partition plate between the heat storage chambers is isolated by gas phase.

Has the advantages that: by adopting the technical scheme, the RTO regenerators are not in a split form adopted in the past, but are combined into a whole and are arranged in a furnace body of the device, the horizontal section of each regenerator is simplified from a single-chamber full-enclosure structure to a single-chamber half-enclosure structure and an integral RTO full-enclosure structure, namely, only a middle partition plate for gas phase isolation between the regenerators does not need to use a heat insulation material, and the regenerator is adjacent to the outside and only uses the heat insulation material. The formed segmented multi-chamber heat accumulating type incinerator can reduce the heat exchange area of a combustion chamber, a heat accumulating chamber and the outside by more than twenty percent, and greatly saves heat insulation materials and steel; at 20000Nm³The calculation of the/h gas volume three-chamber RTO can save more than 15 percent of heat insulation materials and steel. The volume of the combustion chamber is increased under the condition of not increasing the occupied area, the burning efficiency is improved, the heat storage efficiency of the heat storage chamber can be increased, the occupied area of equipment is reduced, and the manufacturing cost of the equipment is reduced. Compared with the prior art:

1. through the upper portion baffle with the change of a segmentation combustion chamber for the segmentation combustion chamber, combustion chamber and regenerator baffle only need high temperature resistant indeformable leak, and need not do the heat preservation of general meaning, can adopt heat accumulation material reinforcing RTO's heat accumulation ability even to not only save insulation material and shell steel construction material, reduce area by a wide margin, still do benefit to RTO steady operation and the improvement of burning efficiency.

2. The increase of the height H of the vertical section of the combustion chamber can multiply the retention time, which is a simple measure for improving the burning rate of the organic gas under the condition of only increasing the burning time without increasing the burning temperature, and the implementation of the measure for increasing the height of the combustion chamber can save a great amount of materials compared with the horizontal increase of the length of the combustion chamber, thereby achieving the effect of multiplying the result with half the effort.

3. The regenerators are isolated only by gas phase, the partition plate material only needs to resist temperature and does not leak, the heat insulation of (N-1) x 2 surfaces and a peripheral steel structure are saved, and indirect heat transfer can be realized among the regenerators due to no heat insulation material, so that the method is a method for heating the regenerators in a lump, and the utilization efficiency of the regenerators is increased.

4. Because heat radiating area reduces, combustion chamber heat dissipation reduces, has improved energy-conserving effect, and simple structure, convenient to use has extensive practicality in this technical field.
