Illustratively, there are multiple sets of injectors 100, each set having two injectors 100, the two injectors 100 being connected to a double wall pipe, respectively. Specifically, the number of the inner branch pipes 112 and the outer branch pipes 122 corresponds one-to-one to the number of the ejectors 100. With continued reference to fig. 1, the number of the ejectors 100 is three groups of six, and of course, the number and arrangement of the ejectors 100 are not limited to this illustrated example, but four groups of eight, and the like.
In the actual installation process, the positions of the ejectors 100 are fixed, and the ejectors 100 are provided with a plurality of groups, each group of ejectors needs to be in installation connection with the corresponding inner branch pipe 112 and outer branch pipe 122, and in consideration of installation errors, in order to facilitate the installation of the double-wall pipe, the inner main pipe 111 comprises an inner flexible part 1111 and an inner hard part 1112, the inner hard part 1112 is connected with the inner branch pipe 112, and two adjacent inner hard parts 1112 are connected through the inner flexible part 1111; the outer main pipe 121 includes an outer flexible portion 1211 and an outer hard portion 1212, the outer hard portion 1212 being connected to the outer branch pipe 122, adjacent two outer hard portions 1212 being connected by the outer flexible portion 1211. The difficulty in installation due to machining or installation errors can be solved by the arrangement of the inner flexible portion 1111 and the outer flexible portion 1211. Further, the number of the inner hard portions 1112 and the outer hard portions 1212 is plural, and the number of both are the same as the number of the sets of the ejectors 100, and the adjacent two outer hard portions 1212 are connected by the outer flexible portion 1211. Alternatively, the inner main pipe 111 may be formed by splicing pipes with the same diameter, that is, the inner flexible portion 1111 and the inner hard portion 1112 have the same diameter. Of course, the inner main pipe 111 may be formed by splicing pipes with different diameters, that is, the diameter of the inner flexible portion 1111 is different from the diameter of the inner hard portion 1112, which is not limited herein. Alternatively, the outer main pipe 121 may be formed by splicing pipes with the same diameter, that is, the outer flexible portion 1211 and the outer hard portion 1212 have the same diameter. Of course, it is preferable that the diameter of the outer rigid tube 1212 be greater than the diameter of the outer flexible tube 1211 to facilitate connection of the desired sensing elements and other tubing elements within the outer rigid tube 1212 while reducing the material cost of the outer flexible portion 1211.
When the amount of methanol leakage is large, there is a problem that methanol cannot volatilize and be discharged in time, based on which the methanol supply device further includes a discharge pipe 71, an inlet of the discharge pipe 71 is connected to the outer hard portion 1212, an outlet thereof is connected to the methanol recovery device 74, and the methanol is discharged to the methanol recovery device 74 in time through the discharge pipe 71.
