[0027] The concentration runner 1 comprises an adsorption zone 11, a cooling zone 12 and a desorption zone 13, each of which is arranged at a different sector of the pie-shaped concentration runner 1, the cooling zone 12 is arranged adjacent to the desorption zone 13, the adsorption zone 11 is used to receive low-concentration organic waste gas, and the cooling zone 12 is used to cool the low-concentration organic waste gas to high concentration;

[0028] The heat exchanger 2 is arranged on one side of the cooling zone 12 and the desorption zone 13, and is used to heat the cooled high-concentration organic waste gas in the cooling zone 12 and make the organic waste gas desorb;

[0029] The furnace body 3 is connected with the desorption zone 13 and the heat exchanger 2 respectively, and is used to receive the desorbed organic waste gas, burn the desorbed organic waste gas, and then introduce the burned organic waste gas to one side of the heat exchanger 2 to assist the heat exchanger 2 in heating;

[0030] The heat recovery RTO furnace body further comprises a secondary combustion pipeline 4 connected between the furnace body 3 and the heat exchanger 2, which is used to transport the assisted heat of the organic waste gas back to the furnace body 3 for secondary combustion, and the organic waste gas is discharged from the furnace body 3 after secondary combustion.

[0031] By the above structure, in use, the operator only needs to introduce the organic waste gas to be treated into the concentration runner 1, so that the adsorption zone 11 in the concentration runner 1 adsorbs the organic matter in the organic waste gas, at this time the organic waste gas is in a low density state, and flows through the adsorption zone 11 of the concentration runner 1 to the cooling zone 12, the cooling zone 12 is cooled by an external cooling device, so that the temperature is reduced, and the density of the organic waste gas is increased to a preset value, and then the high-density organic waste gas is heated by the heat exchanger 2 on one side, so that the organic waste gas is desorbed, and the organic matter is desorbed to the desorption zone 13, and then the desorbed organic waste gas is introduced from the desorption zone 13 of the concentration runner 1 to the downstream of the furnace body 3, and fuel (natural gas in this embodiment) is introduced into the furnace body at the same time, and the treated organic waste gas in the furnace body 3 is burned at high temperature with the aid of the fuel, part of the high-temperature organic waste gas after combustion is introduced into the heat exchanger 2 downstream of the furnace body 3, and the waste heat is utilized, so that part of the heat source in the process of heating the concentration runner 1 by the heat exchanger 2 comes from the combustion of the organic waste gas in the furnace body 3, saving the electric energy required for active heating of the concentration runner 1. Simultaneously, the organic waste gas after auxiliary heating of the heat exchanger 2 reflows into the furnace body 3 from the secondary combustion pipeline 4 and is subjected to secondary combustion, so that the organic waste gas can be treated more cleanly after two combustion processes, and the fuel of the organic waste gas itself is saved.

[0032] Specifically, in the above process, since the organic waste gas cannot be completely combusted in the first combustion process, and a corresponding amount of fuel needs to be introduced to achieve sufficient combustion intensity, the organic waste gas is subjected to secondary combustion in this embodiment, which can realize auxiliary heating of the concentration runner 1 by the heat exchanger 2, and can also burn the organic waste gas more completely, and the amount of fuel introduced in the combustion process is less, indirectly saving fuel, realizing energy saving from multiple angles, and being more environmentally friendly.

[0033] Further, the desorption zone 13 and the furnace body 3 further comprise a desorption windmill 5, which is used to assist the movement of the desorbed organic waste gas to the downstream furnace body 3.

Specifically, when the organic waste gas is subjected to secondary combustion, the combustibility of the organic waste gas is lower, so that the auxiliary combustion is assisted by the introduction of oxygen in this embodiment, so that the final combustion is more sufficient, and the oxygen cost is low and easy to control.

[0035] Further, the organic waste gas after the secondary combustion and the waste gas filtered by the adsorption area 11 are discharged from the same outlet. The same outlet can be the same chimney arranged at the top, facilitating the unified treatment of the final waste gas discharge.

[0036] Further, the furnace body is arranged as a regenerative incinerator. The regenerative incinerator is of a closed structure, and can continuously recover the heat in the waste gas during the combustion process, reducing the energy consumption of the heating process.

[0037] Further, the concentration runner 1 is arranged as a zeolite runner, the core part of which is a runner composed of zeolite material. The zeolite material has a microporous structure and a large specific surface area, and can efficiently adsorb the harmful substances in the waste gas, and is more suitable for the treatment of the organic waste gas in the embodiment.
