Referring to fig. 1 to 3, the present application discloses an exhaust pipe system including a first main pipe 100, a second main pipe 200, and a plurality of branch pipes 300. The second main pipe 200 includes a first pipe segment 210 and a second pipe segment 220, the second pipe segment 220 is connected to two ends of the first pipe segment 210, wherein the pipe diameter of the first pipe segment 210 is larger than that of the second pipe segment 220. The first main pipe 100 communicates with a first pipe section 210. The plurality of branch tubes 300 includes a first sub-tube 310 and a second sub-tube 320, wherein the first sub-tube 310 communicates with the first tube section 210 and the second sub-tube 320 communicates with the second tube section 220.

The first main pipe 100 is an input end of the exhaust pipe system and the branch pipe 300 is an output end of the exhaust pipe system in this application. Wherein, the first part of the steam flow in the first main pipe 100 is discharged through the first pipe section 210 and the first sub-pipe 310 in sequence, and the second part of the steam flow in the first main pipe 100 is discharged through the first pipe section 210, the second pipe section 220 and the second sub-pipe 320 in sequence, and the principle of the design is as follows:

after the steam flow in the first main pipe 100 passes through the first pipe section 210, a part of steam flow (i.e., a first part of steam flow) is distributed to be discharged from the first sub-pipe 310, and as the part of steam flow is distributed, the flow rate of the steam flow (i.e., a second part of steam flow) flowing into the second pipe section 220 will be reduced, so that in order to ensure constant flow rate, the diameter of the second pipe section 220 is set smaller than that of the first pipe section 210, so that under the condition that the cross-sectional area of the pipe sections is reduced, the flow rate of the steam flow in the first pipe section 210 is ensured to be equal to that of the steam flow in the second pipe section 220, and further, the flow rates of the discharged steam flows of the first sub-pipe 310 and the second sub-pipe 320 are ensured to be equal, that the steam flow rates of the branch pipes 300 are ensured to be constant, and the flow rates of the steam flows discharged by the branch pipes 300 are consistent. It can be seen that the discharge uniformity can be improved by this design, as well as the overall discharge efficiency.

Further, the second main pipe 200 also comprises a third pipe section 230. The second pipe section 220 is communicated with the third pipe section 230 and the first pipe section 210 respectively, and the pipe diameter of the second pipe section 220 is larger than that of the third pipe section 230. The plurality of branch pipes 300 further includes a third sub-pipe 330 communicating with the third pipe section 230, and a third portion of the steam flow in the first main pipe 100 is discharged through the first pipe section 210, the second pipe section 220, the third pipe section 230, and the third sub-pipe 330 in sequence.

The second main pipe 200 further comprises a fourth pipe section 240, the third pipe section 230 is respectively communicated with the second pipe section 220 and the fourth pipe section 240, and the pipe diameter of the third pipe section 230 is larger than that of the fourth pipe section 240. The plurality of branch pipes 300 further include a fourth sub-pipe 340 communicated with the fourth pipe section 240, and a fourth portion of the steam flow in the first main pipe 100 is discharged through the first pipe section 210, the second pipe section 220, the third pipe section 230, the fourth pipe section 240 and the fourth sub-pipe 340 in sequence.

After entering the first tube section 210, the vapor stream will be discharged in stages to the second tube section 220, the third tube section 230, and the fourth tube section 240. Similarly, the third pipe section 230 and the fourth pipe section 240 are gradually far away from the first pipe section 210, so that the pipe diameters of the third pipe section 230 and the fourth pipe section 240 are gradually decreased, thereby ensuring that the flow rates of the steam discharged from the first sub-pipe 310, the second sub-pipe 320, the third sub-pipe 330 and the fourth sub-pipe 340 are consistent, improving the discharge uniformity, and further improving the discharge efficiency.

Further, the diameter of the second main pipe 200 decreases from the first pipe section 210 to the fourth pipe section 240, and the second main pipe 200 may be designed as a stepped pipe or a tapered pipe, which will not be described in detail herein.

Further, the second pipe section 220, the third pipe section 230 and the fourth pipe section 240 may be symmetrically disposed on both sides of the first pipe section 210. The first, second, third and

fourth tube segments

210, 220, 230, 240 communicate sequentially in a first direction and in a second direction, wherein the first and second directions are opposite.

The arrangement can be used for arranging more branch pipes 300, and further improves the steam exhaust efficiency.

More specifically, the steam flow in the first main pipe 100 may pass into the second main pipe 200 in a third direction. The branch pipes 300 are all opened towards a third direction, steam in the branch pipes 300 is discharged towards the third direction, and the third direction is intersected with the first direction, such as mutually perpendicular, and the reversing transmission mode is beneficial to saving space.

Further, two first sub-pipes 310 may be provided. The two first sub-pipes 310 are symmetrically arranged along the opening direction of the first main pipe 100, so that the number of the branch pipes 300 to be laid out is larger. Similarly, two second sub-pipes 320 may be provided and are in one-to-one corresponding communication with the second pipe sections 220; two third sub-pipes 330 may be provided and are in one-to-one correspondence with the third pipe sections 230; the number of the fourth sub-pipes 340 may be two, and the four sub-pipes communicate with the fourth pipe sections 240 in a one-to-one correspondence.

Further, the second pipe section 220 may be a tee pipe section to connect the first pipe section 210, the third pipe section 230, and the second sub-pipe 320, respectively. Similarly, the third pipe section 230 may also be a three-way pipe section for connecting the second pipe section 220, the fourth pipe section 240 and the third sub-pipe 330, respectively.

Further, the exhaust pipe system may further include a first curved pipe pressure-balanced compensator 400. The first main pipe 100 is communicated with the second main pipe 200 through the first curved pipe pressure balance type compensator 400. The first curved pipe pressure balance compensator 400 can compensate the axial displacement and the transverse displacement of the exhaust pipeline system, and cannot generate internal pressure thrust to the pipeline system, so that the whole exhaust pipeline system is more flexible.

Similarly, the exhaust pipeline system may further include a second curved pipe pressure balance compensator 500, the second curved pipe pressure balance compensator 500 corresponds to the branch pipes 300 one by one, and the second main pipe 200 is respectively communicated with the corresponding branch pipes 300 through each second curved pipe pressure balance compensator 500. So as to further compensate the axial displacement and the transverse displacement of the exhaust pipeline system.
