One end of the duct 10 (e.g., an upper end of the duct 10 as shown in Figure 2 ) is formed as an air outlet end 11; the hood 20 is sleeved and fixed to the air outlet end 11 of the duct 10; and the limiting piece 30 is connected between the duct 10 and the hood 20, and is configured to limit the hood 20 from being separated from the duct 10 in an axial direction of the duct 10 (e.g., an up-down direction of the duct 10 as shown in Figure 1 ).
[0032] The air pipe 10 is a main channel responsible for gas delivery and distribution in the gasification furnace, and the gas can be combustion-supporting air, preheated gas, etc. The air pipe 10 ensures that the gas provided from outside can enter the furnace interior uniformly and efficiently, and provides necessary oxygen or adjusts the atmosphere in the furnace for the combustion reaction. The air cap 20, as a connecting component between the air pipe 10 and the furnace, can adjust the air outlet angle of the air flow in the air pipe 10, so as to ensure uniform air flow supply. Preferably, the air pipe 10 and the air cap 20 are both cast steel, so that the air pipe 10 and the air cap 20 have good high-temperature resistance and wear resistance. The limiting piece 30 is made of stainless steel, so as to avoid corrosion of the limiting piece 30 caused by liquid erosion.
[0033] The air cap assembly 100 of the utility model sets the limiting piece 30, the limiting piece 30 can limit the air cap 20 along the axial direction of the air pipe 10, so as to prevent the air cap 20 from separating from the air pipe 10, and then the connecting strength of the air cap 20 and the air pipe 10 can be ensured. At the same time, the limiting piece 30 can increase the connecting point of the air cap 20 and the air pipe 10, so as to strengthen the connecting strength of the air cap 20 and the air pipe 10, effectively prevent the air cap 20 from separating from the air pipe 10. Further, the limiting piece 30 is separated from the air pipe 10 and the air cap 20, and the air cap 20 can be separated from the air pipe 10 without damaging the air cap 20. Compared with the scheme in the prior art that the air cap 20 is welded and connected with the air pipe 10 and needs to damage and remove the air cap 20, the air cap assembly 100 of the application can conveniently maintain and repair the air cap 20, save repair time, improve repair efficiency, and also reduce use cost.
[0034] According to the air cap assembly 100 of the embodiment of the utility model, the limiting piece 30 is arranged, the connecting strength of the air cap 20 and the air pipe 10 can be ensured, the air cap 20 can be conveniently maintained, the repair efficiency is improved, and the use cost is also reduced.
[0035] According to some embodiments of the utility model, referring to Figure 1 and Figure 5 , the air cap assembly 100 comprises a connecting plate 40, the connecting plate 40 is fixed on the air pipe 10 and located on one side of the air cap 20 away from the gas outlet end 11 (such as the lower side of the air cap 20 shown in Figure 1 ), the limiting piece 30 is fixed with the air cap 20, the limiting piece 30 is provided with a limiting protrusion 31, the limiting protrusion 31 is arranged on the side of the connecting plate 40 away from the air cap 20 (such as the lower side of the connecting plate 40 shown in Figure 1 ) and in contact with the connecting plate 40 in the axial direction of the air pipe 10.
[0036] In this way, the limiting piece 30 can be connected with the air cap 20 through the connecting plate 40, without directly connecting the limiting piece 30 with the air cap 20, so that when the limiting piece 30 is disassembled, damage of the connecting part of the limiting piece 30 and the air cap 20 can be effectively avoided to cause the air pipe 10 to be damaged, and thus the air pipe 10 can be protected, and meanwhile, the limiting protrusion 31 and the connecting plate 40 abut against each other in the axial direction of the air pipe 10, so that the air cap 20 can be effectively limited in the axial direction of the air pipe 10, which is reasonable in structure and facilitates construction.
[0037] For example, as shown in Figure 1 and Figure 5 , the connecting plate 40 is fixed with the air cap 20, the connecting plate 40 is arranged on the lower side of the air cap 20, the limiting piece 30 is fixed with the air cap 20, the lower end of the limiting piece 30 is provided with the limiting protrusion 31, the limiting protrusion 31 extends towards the air pipe 10 in the radial direction of the air pipe 10, and the upper surface of the limiting protrusion 31 abuts against the lower surface of the connecting plate 40, so as to limit the air cap 20 in the axial direction of the air pipe 10.
[0038] According to some optional embodiments of the present application, referring to Figure 1 , Figure 4 and Figure 5 , the limiting protrusion 31 is point-welded with the connecting plate 40. Thus, the point-welded connection can not only ensure the connection strength of the limiting piece 30 and the connecting plate 40, but also ensure that the limiting piece 30 can be normally separated from the connecting plate 40.
[0039] According to some embodiments of the present application, referring to Figure 1 and Figure 5 , the connecting plate 40 is annular, the outer end of the connecting plate 40 in the radial direction of the air pipe 10 is formed with a first avoiding groove 41, the first avoiding groove 41 penetrates the connecting plate 40 in the thickness direction of the connecting plate 40 (such as the up-down direction of the connecting plate 40 shown in Figure 1 ), and a part of the limiting piece 30 is fitted in the first avoiding groove 41.
[0040] In this way, the first avoiding groove 41 can provide an installation position for the limiting piece 30, so that the installation of the limiting piece 30 can be facilitated, and meanwhile, the space occupied by the limiting piece 30 in the radial direction of the air cap assembly 100 can be reduced, so that the volume of the air cap assembly 100 can be reduced to provide more installation space for other structures.
[0041] For example, as shown in Figure 1 and Figure 5 , the connecting plate 40 is a circular ring, the connecting plate 40 is arranged on the radial outer side of the air pipe 10, the outer end of the connecting plate 40 in the radial direction is provided with the first avoiding groove 41, the first avoiding groove 41 penetrates the connecting plate 40 in the up-down direction, and the lower half of the limiting piece 30 is located in the first avoiding groove 41.
[0042] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 5 The number of limiting members 30 is multiple, that is, the number of limiting members 30 can be two, three or four or more. Multiple limiting members 30 are arranged at intervals along the circumference of the connecting plate 40. The number of first clearance grooves 41 is multiple, that is, the number of first clearance grooves 41 can be two, three or four or more. Multiple first clearance grooves 41 correspond one-to-one with multiple limiting members 30.
[0043] In this way, by setting multiple first clearance grooves 41, clearance space can be provided for multiple limiting members 30, which can facilitate the arrangement of the limiting members 30. At the same time, by setting multiple limiting members 30, multiple connection points can be provided between the hood 20 and the duct 10, thereby ensuring the connection strength between the hood 20 and the duct 10 and effectively preventing the hood 20 from separating from the duct 10.
[0044] For example, such as Figure 1 and Figure 5 As shown, there are six first clearance grooves 41, which are arranged at intervals along the circumference of the connecting plate 40. There are also six limiting members 30, with one limiting member 30 in each first clearance groove 41.

The second clearance grooves 21 penetrate the outer peripheral surface of the air cap 20 along the radial direction of the air duct 10. The plurality of second clearance grooves 21 correspond one-to-one with the plurality of first clearance grooves 41. The second clearance grooves 21 and the corresponding first clearance grooves 41 are directly opposite and connected in the axial direction of the air duct 10. A part of the limiting member 30 is located in the second clearance grooves 21.
[0046] In this way, the first clearance groove 41 and the second clearance groove 21 cooperate to provide a connected clearance space for the limiting member 30, which facilitates the arrangement of the limiting member 30. At the same time, the second clearance groove 21 is set in a reasonable position and does not affect the structural strength of the wind cap 20, thus ensuring the service life of the wind cap 20.
[0047] For example, such as Figure 1 and Figure 3As shown, the lower end of the hood 20 is provided with six second avoiding grooves 21 formed by upward concave, the six second avoiding grooves 21 are arranged along the circumferential direction of the hood 20, and each second avoiding groove 21 is correspondingly connected with the corresponding first avoiding groove 41 in the vertical direction, and the upper half of the limiting piece 30 is located in the second avoiding groove 21.

Thus, the connection mode of spot-welding can not only ensure the connection strength of the limiting piece 30 and the hood 20, but also ensure that the limiting piece 30 can be normally separated from the hood 20.
[0049] According to some embodiments of the present application, as shown in Figure 1 and Figure 3 , a gas passage 22 is formed in the hood 20, the gas passage 22 is communicated with the gas outlet end 11 of the air pipe 10, and a plurality of through holes 23 are arranged on the side wall of the hood 20, that is, two, three or more than four through holes 23 can be arranged on the side wall of the hood 20, and the plurality of through holes 23 are arranged along the circumferential direction of the hood 20 and communicated with the gas passage 22.

[0052] According to some embodiments of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the hood 20 is screw-connected with the air pipe 10. Thus, this connection mode is simple and convenient for construction, so that the assembly efficiency can be improved, and at the same time, the hood 20 and the air pipe 10 can be conveniently disassembled, and the maintenance and repair of the hood 20 are facilitated.
