DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the cyclone separator of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0029] like Figure 1 As shown in FIG. , a cyclone separator comprises: a cyclone element 1. Figure 2 , 3 As shown in Figures 4 and 5, the swirl molecule 1 has a shell 2. A cooling cavity 3 is provided in the shell wall of the shell 2, and a refrigerant inlet 4 for allowing external refrigerant to enter the cooling cavity 3 and a refrigerant outlet 5 for allowing the refrigerant in the cooling cavity 3 to be discharged to the outside of the cooling cavity 3 are provided on the surface of the shell 2. The external refrigerant can enter the cooling cavity 3 through the refrigerant inlet 4 and exchange heat with the substance entering the swirl molecule 1, and then be discharged to the outside of the cooling cavity 3 through the refrigerant outlet 5. In actual use, when the dust-containing synthesis gas produced from the outlet of the gasifier enters the swirl molecule 1, the refrigerant flowing through the cooling cavity 3 can cool the dust in the synthesis gas and / or the dust separated from the synthesizer, so as to prevent it from being in a molten state and adhering to the inner wall of the swirl molecule 1, thereby preventing the swirl molecule 1 from being blocked. It should be noted that the refrigerant can be water, but is not limited thereto, and other substances that can achieve the purpose of the invention can also be used.

[0030] Specifically, Figure 2 , 3 As shown in Figures 4 and 5, the housing 2 includes an upper shell 6 and a lower shell 7 which are arranged from top to bottom and connected to each other. The outer contour of the upper shell 6 is cylindrical, and the outer contour of the lower shell 7 is a truncated cone whose axis coincides with the axis of the upper shell 6 and tapers away from the upper shell 6.

[0031] Preferably, the housing 2 includes an upper shell 6 and a lower shell 7 arranged from top to bottom and connected to each other. The outer contour shape of the upper shell 6 is cylindrical, and the outer contour shape of the lower shell 7 is a truncated cone with an axis coinciding with the axis of the upper shell 6 and gradually tapering away from the upper shell 6.

[0032] Several optional configurations of the cooling chamber 3 in the shell wall of the shell 2 are introduced below:

[0033] 1. The first arrangement form of the cooling chamber 3

[0034] like Figure 2As shown, the cooling chamber 3 includes a first cooling channel 8 arranged in the shell wall of the lower shell 7. The first cooling channel 8 includes an ascending section 9, a connecting section 10 and a descending section 11 which are connected in sequence. The extending direction of the ascending section 9 is the same as the extending direction of the generatrix of the outer profile of the lower shell 7, and a refrigerant inlet 4 is formed at the bottom end of the lower shell 7. The extending direction of the descending section 11 is the same as the extending direction of the generatrix of the outer profile of the lower shell 7, and a refrigerant outlet 5 is formed at the bottom end of the lower shell 7. With such a structural form, the refrigerant enters the ascending section 9 through the refrigerant inlet 4 and flows on the refrigerator, then enters the descending section 11 through the connecting section 10, and is discharged from the refrigerant outlet 5 after flowing through the descending section 11. In actual production, the number of the first cooling channels 8 is at least two, and at least two first cooling channels 8 are evenly arranged along the circumference of the lower shell 7. In this way, the cooling effect can be guaranteed.

[0035] 2. The second arrangement form of the cooling chamber 3

[0036] like Figure 3 As shown, the cooling chamber 3 includes a second cooling channel 12 arranged in the shell wall of the lower shell 7 and a third cooling channel 13 arranged in the shell wall of the upper shell 6. The extension direction of the second cooling channel 12 is the same as the extension direction of the busbar of the outer profile of the lower shell 7, and a refrigerant inlet 4 is formed at the bottom end of the lower shell 7. The extension direction of the third cooling channel 13 is the same as the extension direction of the busbar of the outer profile of the upper shell 6, and a refrigerant outlet 5 is formed at the top end of the upper shell 6. The top end of the second cooling channel 12 is connected to the bottom end of the third cooling channel 13, so that the refrigerant entering the second cooling channel 12 from the refrigerant inlet 4 can enter the third cooling channel 13 and be discharged through the refrigerant outlet 5. In this way, the refrigerant can enter the second cooling channel 12 through the refrigerant inlet 4 and flow into the third cooling channel 13 on the refrigerator. The refrigerant entering the third cooling channel 13 continues to flow upward and is discharged from the refrigerant outlet 5. In actual production, the number of the second cooling channels 12 is at least two, and at least two second cooling channels 12 are evenly arranged along the circumference of the lower shell 7 . The number of the third cooling channels 13 is equal to the number of the second cooling channels 12 and corresponds one to one.

[0038] like Figure 4As shown, the lower shell 7 is formed by a first tube 14 wound in a spiral shape, and the upper shell 6 is formed by a second tube 15 wound in a spiral shape. The first tube 14 and the second tube 15 are connected so that the inner cavity of the first tube 14 and the inner cavity of the second tube 15 together form a cooling cavity 3. The end of the first tube 14 away from the second tube 15 is in an open state to form a refrigerant inlet 4, and the end of the second tube 15 away from the first tube 14 is in an open state to form a refrigerant outlet 5. In this way, the refrigerant enters the first tube 14 from the refrigerant inlet 4, and flows through the first tube 14 and the second tube 15 in sequence, and is discharged from the refrigerant outlet 5. In actual production, Figure 4 As shown in the figure, a first wear-resistant component 16 is laid on the inner wall of the lower shell 7 to make the inner wall of the lower shell 7 smooth; and / or, a second wear-resistant component 17 is laid on the inner wall of the upper shell 6 to make the inner wall of the upper shell 6 smooth. The first wear-resistant component 16 and the second wear-resistant component 17 can be stainless steel plates, but are not limited thereto, and can also be other components that can achieve the design purpose (such as refractory casting blocks, etc.).

[0039] As an implementation method, Figure 1 As shown, the cooling chamber 3 further includes a refrigerant input main pipe 18, a refrigerant discharge main pipe 19, a refrigerant input branch pipe 20 and a refrigerant discharge branch pipe 21. One end of the refrigerant input branch pipe 20 is connected to the refrigerant input main pipe 18, and the other end is connected to the refrigerant inlet 4. The refrigerant input main pipe 18 can be connected to an external refrigerant source so that the refrigerant in the external refrigerant source can enter the cooling chamber 3 through the refrigerant input main pipe 18 and the refrigerant input branch pipe 20 at one time. One end of the refrigerant discharge branch pipe 21 is connected to the refrigerant discharge main pipe 19, and the other end is connected to the refrigerant outlet 5. The refrigerant discharge main pipe 19 can be connected to an external target position so that the refrigerant in the cooling chamber 3 can flow to the external target position through the refrigerant discharge branch pipe 21 and the refrigerant discharge main pipe 19 in sequence. Furthermore, there are multiple swirl molecules 1, the number of refrigerant input branches 20 is equal to the total number of refrigerant inlets 4 on the multiple swirl molecules 1, and they correspond one to one, and the number of refrigerant discharge branches 21 is equal to the total number of refrigerant outlets 5 on the multiple swirl molecules 1, and they correspond one to one.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
