Fig. 1 is a schematic view of a tandem incinerator apparatus according to an embodiment of the present application.

The series incinerator apparatus may include a rotary kiln incinerator 1 and a scaleboard incinerator 2.

The rotary kiln incinerator 1 as shown in fig. 2 may include a refractory lining 1-1, a furnace body 1-2 and a support 1-3. The lining furnace 1-1 of the rotary kiln incinerator 1 is arranged inside the furnace body 1-2, and the furnace body 1-2 and the lining furnace 1-1 made of refractory materials are fixed by a support 1-3. The furnace body 1-2 is arranged on the bracket 1-3 within the range of 0-3 degrees of inclination angle. In burning industrial waste, the waste is introduced from an inlet of a rotary kiln incinerator body 1-2, heated by a lining 1-3 of refractory material to burn the waste. The furnace body 1-2 of the rotary kiln incinerator is installed at a certain inclination angle so that the furnace body of the rotary kiln incinerator slowly rotates, and waste supplied from the upper part of the furnace body of the rotary kiln incinerator is transferred to the lower part, and air is supplied from the front part or the rear part to be incinerated.

As shown in figure 3, the apron furnace incinerator 2 comprises an incinerator main furnace 2-1 and an apron furnace 2-2, the apron furnace 2-2 is arranged inside the incinerator main furnace 2-1, and the incinerator main furnace 2-1 is connected with the rotary kiln incinerator 1 through a flue gas pipeline.

Fig. 2 is a schematic view of a rotary kiln incinerator apparatus according to an embodiment of the present application.

According to the embodiment of the present application, the furnace body 1-2 of the rotary kiln incinerator may be a cylindrical furnace body made of steel plate. As the refractory material of the rotary kiln incinerator needs to reach the temperature of about 800 ℃ during incineration, the furnace body 1-2 of the rotary kiln incinerator can be made of the refractory material with the melting point of more than 1500 ℃, so that the rotary kiln incinerator can be used for a long time and is not easy to damage. The furnace body 1-2 of the rotary kiln incinerator is arranged to be cylindrical so as to facilitate the rotation of the furnace body of the rotary kiln incinerator, and further achieve the purpose that waste can be fully incinerated in the rotary kiln incinerator.

According to the embodiment of the present application, the number of the refractory lining furnaces 1-1 of the rotary kiln incinerator can be two or more, and the refractory lining furnaces are arranged at intervals in the range of the furnace body 1-2 of the rotary kiln incinerator.

The rotary kiln incinerator has the advantages of long retention time, good heat insulation and the like, and the waste material layer is fully turned over due to the rotation action. The rotary kiln incinerator has strong adaptability to changes of incinerated substances, so that the rotary kiln incinerator can become an ideal incineration system for high COD (chemical oxygen demand), high-calorific-value wastewater and solid wastes. The rotary kiln incinerator 1 is not suitable for incineration treatment of high-salt waste.

According to the embodiment of the present application, the apron furnace incinerator 2 may include an incinerator main furnace 2-1 and an apron furnace 2-2. The incinerator main furnace 2-1 may be divided into an upper half and a lower half.

The flue gas from the flue gas pipeline enters the upper half part of the incinerator main furnace 2-1, wherein the flue gas also comprises high-salt waste which is not incinerated in the rotary kiln incinerator 1. After the waste enters the scaly incinerator 2, the incineration temperature of the scaly incinerator 2 can reach 850 ℃, so that the high-salt-content waste which is not incinerated can be sufficiently incinerated by the scaly incinerator 2-2.

According to the embodiment of the present application, the series incinerator apparatus further comprises a high temperature cyclone apparatus 3, and the high temperature cyclone apparatus 3 has a gas inlet and a gas outlet. The smoke generated by incinerating the waste in the scaly plate incinerator 2 can be discharged from the upper half part of the main furnace 2-1 of the scaly plate incinerator to enter the high-temperature cyclone device 3. The gas inlet of the high-temperature cyclone device 3 is tightly connected with the gas outlet of the upper half part of the main furnace 2-1 of the apron furnace so as to reduce the heat of the flue gas in the process as much as possible. The flue gas is rotated and separated by a high-temperature cyclone device under a high-temperature state to obtain larger particles of the flue gas.

According to the embodiment of the application, the series incinerator device further comprises two combustion chambers 4, the two combustion chambers 4 are provided with gas inlets and gas outlets, and the gas outlets of the high-temperature cyclone device 3 are connected with the gas inlets of the two combustion chambers 4.
