[0036] The method of hazardous waste incineration is widely adopted by countries around the world because of its advantages such as simplicity, high efficiency and environmental protection. The incinerator body is the most important equipment in the incineration system, and the furnace wall is often an important source of heat loss in the incinerator.

[0037] In current technology, the insulation effect of the furnace wall is poor, which leads to heat loss during the combustion process and causes high energy consumption of the incineration device.

[0038] At the same time, in order to obtain better thermal insulation effect, the incinerator will be equipped with a thicker lining to obtain better thermal insulation effect, but the thicker lining will cause the volume of the incinerator to become larger.

[0039] In order to solve the technical problem of high energy consumption of incineration equipment caused by poor insulation effect of furnace wall, the first embodiment of this application provides an incinerator, please refer to Figure 1 , Figure 1 A structural schematic diagram of an incinerator provided in an embodiment of the present application, the incinerator includes an inner shell 10 and an outer shell 20, the inner shell 10 has a first chamber 11, the inner shell 10 has a first air inlet 12, the first air inlet 12 is connected to the first chamber 11; the outer shell 20 has a second chamber 21, the outer shell 20 has a second air inlet 22, the second air inlet 22 is connected to the second chamber 21; the inner shell 10 is penetrated by the second chamber 21, and there is a gap 25 between the outer shell 20 and the inner shell 10, the gap 25 is connected to the first air inlet 12 and the second air inlet 22 respectively; the gap 25 receives the heat preservation medium introduced from the second air inlet 22, the heat preservation medium is heated by the inner shell 10 and passes into the first chamber 11 from the first air inlet 12 along the gap 25.

[0040] In the first embodiment of the present application, a gap 25 is provided between the inner shell 10 and the outer shell 20, and a heat-insulating medium is injected therein to improve the heat-insulating effect of the incinerator, thereby reducing the heat loss of the incinerator at the shell. In addition, in the first embodiment of the present application, a first air inlet 12 is provided on the inner shell 10 so that the heat-insulating medium in the gap 25 can flow into the first chamber 11, thereby bringing part of the heat lost from the inner shell 10 into the first chamber 11, thereby increasing the temperature in the first chamber 11, thereby realizing the recycling of the heat lost at the inner shell 10, further reducing the heat loss, and thus reducing the energy consumption of the incinerator. In addition, since the incinerator can obtain a better heat-insulating effect by providing a gap 25 and injecting a heat-insulating medium therein, the lining thickness of the incinerator is reduced and the volume of the incinerator is reduced under the premise that the heat-insulating effect remains unchanged.

[0041] Specifically, the heat-insulating medium may be air. Air has a good heat-insulating effect. The air in the gap 25 and serving as the heat-insulating medium can reduce the heat lost from the inner shell 10 .

[0042] Furthermore, a fan is provided at the second air inlet 22 to drive the flow of the heat-insulating medium, so that the heat-insulating medium collects the heat lost from the inner shell 10 and brings it into the first chamber 11 .

[0043] Furthermore, the number of the second air inlets 22 is at least 2, and the plurality of second air inlets 22 are arranged at equal angles along the circumference of the outer shell 20 so that the heat preservation medium entering the gap 25 through the second air inlets 22 can be distributed in the gap 25 as evenly as possible.

[0044] In some embodiments, please refer again to Figure 1 The inner shell 10 has a burner mounting hole 13 , and the second air inlet 22 is located along the first direction X on a side of the first air inlet 12 away from the burner mounting hole 13 .

[0045] Furthermore, the burner mounting hole 13 is used to mount the burner. When in use, the burner is inserted into the mounting hole and connected to the inner shell 10 .

[0046] In the above embodiment, the second air inlet 22 is far away from the burner mounting hole 13. Such a setting can make the path of the insulation medium flowing from the second air inlet 22 to the first air inlet 12 as long as possible, so as to collect as much heat lost from the inner shell 10 as possible, thereby improving the efficiency of heat recovery, thereby further reducing the heat loss of the incinerator.

[0047] In some embodiments, please refer again to Figure 1 The inner shell 10 includes a connecting portion 14 , a tapered portion 15 and a combustion portion 16 which are sequentially connected along a first direction X, the burner mounting hole 13 is arranged at the connecting portion 14 , and the first air inlet 12 is arranged at the tapered portion 15 .

[0048] In the above embodiment, the flow cross-sectional area at the conical portion 15 becomes larger, and the flow velocity of the fluid in the conical portion 15 decreases. Setting the first air inlet 12 at the conical portion 15 can extend the residence time of the insulation medium in the conical portion 15 so that the insulation medium can heat the exhaust gas as much as possible, thereby improving the combustion efficiency of the incinerator, thereby further reducing the energy consumption of the incinerator.

[0049] In some embodiments, please refer again to Figure 1 The tapered portion 15 further has a third air inlet 151 , and the third air inlet 151 is located along the first direction X between the first air inlet 12 and the second air inlet 22 .

[0050] In the above embodiment, the third air inlet 151 for taking in the exhaust gas is located between the first air inlet 12 and the second air inlet 22 in the first direction X, which can make the combustion effect better.

[0051] In some embodiments, the outer shell 20 includes a main body portion 23 and a bellows portion 24, the combustion portion 16 is penetrated through the main body portion 23, and the second air inlet 22 is located at the main body portion 23; the bellows portion 24 is connected to the main body portion 23, and the conical portion 15 is penetrated through the bellows portion 24; the bellows portion 24 has a spray gun interface 241, and the spray gun interface 241 is used to connect the spray gun so that the spray gun can be inserted into the third air inlet 151.

[0052] Specifically, since the bellows portion 24 is located outside the conical portion 15, the gap 25 between the bellows portion 24 and the conical portion 15 is larger than the gap 25 between the main body portion 23 and the combustion portion 16. The flow rate of the fluid here is reduced, that is, the flow rate of the insulation medium here is reduced and the residence time is extended, so that the insulation medium can fully exchange heat with the conical portion 15 to increase the temperature inside the conical portion 15, thereby reducing the energy consumption of the incinerator and improving the combustion efficiency of the incinerator.

[0053] Furthermore, the bellows portion 24 also has a vent to facilitate the discharge of the heat-insulating medium in the gap 25 when the incinerator is inspected and maintained.

[0054] Furthermore, a through hole is formed on a surface of the bellows portion 24 close to the burner mounting hole 13 along the first direction X, and the connecting portion 14 is passed through the through hole and connected to the bellows portion 24 .

[0055] Furthermore, the gap includes a first gap, a first gap is provided between the bellows portion 24 and the conical portion 15, a second gap is provided between the main body portion 23 and the combustion portion 16, and the second air inlet 22 is connected to the second gap so that the thermal insulation medium surrounds the combustion portion 16 as much as possible, so that the thermal insulation effect of the combustion portion 16 is better.

[0056] Furthermore, the second air inlet 22 is located at one end of the main body 23 away from the bellows portion along the first direction. More specifically, the thermal insulation medium entering the second gap through the second air inlet 22 can flow from one end of the combustion portion 16 to the other end along the first direction, so that the combustion portion 16 obtains a better thermal insulation effect.

[0057] In some embodiments, see Figure 2 and Figure 3 , Figure 2 for Figure 1 The cross-sectional view at AA in the middle. Figure 3 for Figure 2 As shown in the detail diagram at the middle circle D, the incinerator also includes a plurality of support ribs 30, which extend along the first direction X. The support ribs 30 are arranged in the gap 25, one side of the support ribs 30 is connected to the outer wall of the inner shell 10, and the other side of the support ribs 30 is connected to the inner wall of the outer shell 20; the plurality of support ribs 30 are arranged at intervals and are arranged in a ring around the inner shell 10.

[0058] It is understandable that, since there is a gap 25 between the inner shell 10 and the outer shell 20, providing the support rib 30 in the gap 25 can avoid relative movement between the inner shell 10 and the outer shell 20, making the connection between the inner shell 10 and the outer shell 20 more stable.

[0059] Furthermore, the supporting ribs 30 are arranged at equal angles in the gap 25 and are connected to the combustion part 16 and the body part 23 respectively.

[0060] Furthermore, one side of the support rib 30 is connected to the combustion part 16 , and the other side of the support rib 30 is connected to the main body 23 , so as to form a support between the combustion part 16 and the main body 23 .

[0061] In some embodiments, please refer again to Figure 1 Also see Figure 4 , Figure 4 for Figure 1 A cross-sectional view of the throttle plate 40 at the middle BB. The incinerator also includes a throttle plate 40, which is arranged in the gap 25. The throttle plate 40 is respectively connected to the inner shell 10 and the outer shell 20. The throttle plate 40 has a plurality of throttling holes 41 so that the heat-insulating medium entering the gap 25 can flow along the circumference of the inner shell 10.

[0062] It is understandable that the gap 25 is an annular gap 25, and the heat preservation medium entering the gap 25 from the second air inlet 22 is difficult to be evenly distributed in the circumferential direction of the gap 25. In the above embodiment, by providing a throttle plate 40 with a plurality of throttle holes 41, the heat preservation medium entering the gap 25 from the second air inlet 22 can be evenly distributed in the circumferential direction of the gap 25 as much as possible, avoiding the existence of local high temperature points, thereby improving the heat preservation and heat collection efficiency of the heat preservation medium.

[0063] In some embodiments, please refer again to Figure 3 Also see Figure 5 , Figure 5 for Figure 1 In the detailed view at the middle circle C, the incinerator further includes a heat-insulating layer 50 , which is disposed in the gap 25 . The heat-insulating layer 50 is disposed around the inner shell 10 and is connected to the inner shell 10 .

[0064] Furthermore, the thermal insulation layer 50 is made of rock wool blanket or aluminum silicate fiber blanket to provide better thermal insulation effect for the inner shell 10 .

[0065] In the above embodiment, the thermal insulation layer 50 is applied outside the inner shell 10 to further improve the thermal insulation performance at the gap 25, thereby avoiding heat loss in the inner shell 10 as much as possible, thereby reducing the energy consumption of the incinerator and improving the combustion efficiency of the incinerator.

[0066] In some embodiments, please refer again to 3 and Figure 5, the thickness of the thermal insulation layer 50 is smaller than the minimum dimension of the gap 25 along the second direction Y.

[0067] In the above embodiment, by limiting the thickness of the thermal insulation layer 50, the gap 25 can obtain good thermal insulation performance and reduce the thickness to a minimum, so as to reduce the volume of the incinerator while ensuring the thermal insulation performance of the incinerator.

[0068] In some embodiments, please refer again to Figure 3 and Figure 5 The incinerator further includes a refractory layer 60 , which is located in the first chamber 11 . The refractory layer 60 is arranged around the inner shell 10 and connected to the inner wall of the inner shell 10 .

[0069] Furthermore, the refractory layer 60 is made of high-alumina mullite bricks or andalusite bricks.

[0070] In the above embodiment, the fire-resistant layer 60 is provided to prevent the inner shell 10 from being burned and to extend the service life of the inner shell 10. In addition, the fire-resistant layer 60 also has a certain thermal insulation effect. The fire-resistant layer 60 can also reduce the heat loss in the inner shell 10, thereby reducing the energy consumption of the incinerator and improving the combustion efficiency of the incinerator.

[0071] In some embodiments, please refer again to Figure 5 The incinerator further includes a plurality of temperature sensors 70 , which are located in the gap 25 , are connected to the outer wall of the inner shell 10 , and at least some of the plurality of temperature sensors 70 are arranged at intervals along the first direction X.

[0072] In the above embodiment, a plurality of temperature sensors 70 are provided to monitor the temperature outside each section of the inner shell 10, so as to determine the heat loss at the inner shell 10 and further control the flow rate of the heat preservation medium at the second air inlet.

[0073] Specifically, when the temperature value of the temperature sensor 70 exceeds the preset temperature value, the flow rate of the thermal insulation medium at the second air inlet is increased to bring as much heat lost in the inner shell 10 as possible into the first chamber 11; when the temperature value of the temperature sensor 70 is lower than the preset temperature value, the flow rate of the thermal insulation medium at the second air inlet is maintained.

[0074] In some embodiments, please refer again to Figure 5 The incinerator includes at least one expansion joint 27, which is connected to the outer wall of the outer shell.

[0075] Further, when there are multiple expansion joints 27 , the multiple expansion joints 27 are arranged along the first direction. Specifically, the expansion joints 27 are arranged around the outer wall of the outer shell 20 .

[0076] In the above embodiment, an expansion joint 27 is provided between adjacent cylinder walls 26 to compensate for deformation of the outer shell 20 due to temperature increase, specifically, including deformation along the axial and radial directions of the shell 20 , so as to increase the service life of the outer shell 20 .

[0077] Accordingly, the present application also provides an incineration device, including the incinerator of any one of the above embodiments. The incineration device uses the incinerator of the above embodiment to introduce the heated air in the gap 25 into the furnace cavity, thereby collecting the heat lost from the furnace wall and continuing to introduce it into the furnace cavity for reuse, thereby reducing the energy consumption of the incinerator and reducing heat loss.
