Described spool is cylinder, steam input pipe is connected to the axis part of spool, the input of described steam hole is provided in the blind hole at spool axle center place, the outfan of steam hole includes being arranged on spool sidewall, the groove of axial distribution and be arranged in spool radially-arranged intercommunicating pore, and the two ends of described intercommunicating pore are respectively communicated with the input of groove and steam hole.

Adopting after technique scheme, this outstanding buried tube type reactor adopts a reversal valve can change the duty of multiple pipeline simultaneously, it is to avoid the generation of maloperation, purges work convenient and swift, can avoid the loss of raw material that maloperation causes and steam.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model will be further described.

nullAs shown in Figure 1，The energy-efficient sour method composite heat transfer of one described in the utility model includes cylinder 1 with outstanding buried tube type reactor、It is fixedly mounted on the orbit ring 2 on cylinder 1 outer wall、Ring gear 3，Ring gear 3 engages with driving gear 9，Orbit ring 2 is arranged on rail wheel 10，The inner chamber of cylinder 1 is provided with shower 4 and overflow pipe 7，Described overflow pipe 7 is the sidewall blind pipe with spout hole，Described shower 4 is the blind pipe that sidewall is provided with nozzle 5，The porch of described cylinder 1 is provided with reversal valve 6，Described reversal valve 6 includes valve casing 61、Rotatably coordinate the spool 62 being arranged in valve casing 61，Valve casing 61 is provided with spray input pipe 63、Spray outlet tube 64、Overflow input pipe 65、Overflow outlet tube 66 and steam input pipe 67，Spray outlet tube 64 connects shower 4，Overflow input pipe 65 connects overflow pipe 7，Spool 62 is provided with spray through hole 68 and overflow through hole 69 and steam hole，Described spray through hole 68 and overflow through hole 69 are provided in the through hole in spool 62；As in figure 2 it is shown, when being respectively communicated with spray input pipe 63 and spray outlet tube 64 at the two ends spraying through hole 68, overflow through hole 69 connects overflow input pipe 65 and overflow outlet tube 66 simultaneously；Described steam hole is the threeway duct of input and steam input pipe 67 normal open, and two outfans of steam hole are respectively used to connection spray outlet tube 64 and overflow outlet tube 66.

Described spool 62 is cylinder, as shown in Figure 4, steam input pipe 67 is connected to the axis part of spool 62, the input of described steam hole is provided in the blind hole at spool 62 axle center place, the outfan of steam hole includes being arranged on spool 62 sidewall, the groove A of axial distribution and the two ends that are arranged in spool 62 radially-arranged intercommunicating pore B, described intercommunicating pore B are respectively communicated with the input of groove A and steam hole.

As shown in Figure 2, Figure 4 shows, during normal production work, the two ends of spray through hole 68 are respectively communicated with spray input pipe 63 and spray outlet tube 64, overflow through hole 69 connects overflow input pipe 65 and overflow outlet tube 66, now two groove A of steam hole are all blocked by the inwall of valve casing 61, be equivalent to steam input pipe 67 be closed, liquefied ammonia enters shower 4 by spraying input pipe 63, spray through hole 68, spraying outlet tube 64 and is sprayed onto on material, sulphuric acid is then entered overflow pipe 7 flowed out by overflow input pipe 65, overflow through hole 69, overflow outlet tube 66, with mixing of materials.

As shown in Figure 3, it is necessary to when parking purges, as long as the spool 62 of reversal valve 6 being rotated a certain angle by handle, making two groove A of steam hole be respectively aligned to spray outlet tube 64 and overflow outlet tube 66, steam can be inputted, it is achieved purging.Now owing to spray through hole 68 and overflow through hole 69 turn over certain angle with spool 62, deviate from the mouth of pipe of spray input pipe 63 and overflow input pipe 65, be equivalent to block both, do not affect depositing of raw material.
