As shown in fig. 3 and 4, the incinerator 1 includes: the air inlet and outlet switching bellows 11 is positioned at the bottom of the furnace body and is respectively communicated with the air supply mechanism 2 through an incineration air inlet pipe 111, the waste heat recovery mechanism 3 through an incineration exhaust pipe 112 and the clean air through a back flushing pipe 113; at least three regenerators 12 located on the upper side of the air inlet/outlet switching bellows 11 and communicated with the air inlet/outlet switching bellows 11 through corresponding switching valves 121; and an incineration chamber 13 located at the upper part of the furnace body and communicating with the regenerative chamber 12.
In this embodiment, optionally, a heat-accumulating ceramic layer 122 is arranged in the heat-accumulating chamber 12 for heat exchange between the exhaust gas and the gas discharged from the incinerator 1; and heat insulation layers 123 are arranged in the wall of the regenerative chamber 12 and the wall of the incineration chamber 13.
In this embodiment, optionally, a burner 131 is disposed in the incineration chamber 13, and can assist combustion of the exhaust gas in the incineration chamber 13 to reach an oxidation temperature; the top of the incineration chamber 13 is provided with a thermal bypass valve 132, which can be used for pressure relief protection.

In an alternative application, the number of regenerators 12 is five, and two are selected as the inlet, two as the outlet, and one as the purge during a process cycle. High-concentration organic waste gas enters the bottom air inlet and outlet switching air box 11 through the waste gas air inlet machine 21, then enters the heat storage ceramic layer 122 of 2 air inlet heat storage chambers distributed in the air inlet heat storage air box (the heat storage ceramic layer 122 stores the heat of the last cycle and is in a high-temperature state), at the moment, the heat storage ceramic layer 122 releases the heat, the temperature is reduced, the organic waste gas absorbs the heat, the temperature is increased, the waste gas enters the incineration chamber 13 at a higher temperature (680 and 820 ℃) after heat exchange of the air inlet 2 heat storage chambers, so that the organic matters are oxidized and decomposed into harmless CO2 and H2O, if the temperature of the waste gas does not reach the oxidation temperature, the combustion machine 131 directly heats and compensates the oxidation temperature, because the waste gas is preheated in the air inlet heat storage chambers, the waste gas enters the incineration chamber 13 and can reach the oxidation temperature only by slightly heating (if the concentration of the waste gas is high enough, natural gas heating is not needed during oxidation, and spontaneous combustion and waste heat utilization can be maintained by the heat released by the oxidative decomposition of the organic matters), the oxidized high-temperature gas is discharged through 2 gas outlet regenerators 12. (at this moment, the heat storage ceramic layer 122 is in a low temperature state), the high-temperature gas releases a large amount of heat to the heat storage ceramic layer 122, the gas is cooled, and the heat storage ceramic layer 122 absorbs the large amount of heat and then is heated and stored (for preheating the organic waste gas in the next cycle), and the clean gas is discharged under the action of a fan. After an incineration cycle is finished, the waste gas is sucked back by the waste gas inlet machine 21, and untreated waste gas remained in the incinerator in the previous cycle is removed by the regenerator 12 for purging, so that the phenomenon of discharge error and short discharge time which are not up to standard is prevented.
In this embodiment, the method of distributing a regenerator 12 through the switching valve 121 as an outlet, inlet and purge in an incineration cycle is prior art, and the present invention does not improve the related program control.
