Embodiment 1, refer to fig. 1-3 and 5, provides a fuel gas distribution pipe of a catalytic cracking device regenerator, which can achieve the effect of uniformly spraying fuel gas in a fuel mixing pipe 200, solves the problem that a common fixed fuel gas distribution pipe has insufficient mixing in a fuel mixing pipe 200 with a larger caliber, comprises the fuel mixing pipe 200, further comprises a fuel gas dispersing mechanism 100 arranged in the fuel mixing pipe 200, and comprises a rotary supporting component 101 and a rotary dispersing component 102 arranged on the rotary supporting component 101, wherein the rotary supporting component 101 comprises a fixed seat 101a, the fixed seat 101a is connected with the inner wall of the fuel distribution pipe, the fixed seat 101a is rotationally connected with a rotary disc 101b, and a sealing component 103 is arranged between the fixed seat 101a and the rotary disc 101 b; the rotary distributor assembly 102 comprises a distributor tube 102a connected to the turntable 101b and a booster ring 102b connected to the inner wall of the fuel mixing tube 200, wherein the nozzle 102a-1 is arranged on one side of the distributor tube 102a, the booster ring 102b is coaxial with the turntable 101b, and the tail end of the distributor tube 102a is sleeved with the booster ring 102 b.
The device realizes even dispersion of fuel gas by rotating the dispersing pipes 102a at high speed in the fuel mixing pipe 200, each dispersing pipe 102a is provided with a row of nozzles 102a-1, the nozzles 102a-1 are used for dispersing the fuel gas and also provide thrust when the dispersing pipes 102a rotate, the rotating paths of the nozzles 102a-1 replace the traditional fixed annular and C-shaped fixed pipe fittings, obviously, when the nozzles 102a-1 move at high speed on the annular path and spray the fuel gas, the effect is equivalent to that of each nozzle 102a-1, and the dispersing pipe 102a-1 is provided with a dispersing effect of one conventional fixed pipe fitting, and the connecting and combining of a plurality of conventional layout pipe fittings are easier, so that the rotating dispersing assembly 102 not only can replace the complicated traditional fixed dispersing pipe 102a pieces, but also has the characteristics of simple structure, material saving and easy processing;
it should be noted that the necessity of the booster ring 102b in the rotary distribution assembly 102: the reaction force generated by injecting the fuel gas through the conventional opening nozzle 102a-1 is difficult to realize the high-speed rotation of the dispersion pipe 102a in practical applications, and particularly in the above, more opening nozzle 102a-1 is needed to improve the uniform effect of the fuel gas dispersion, which results in further reduction of the pressure and flow rate of the injected fuel gas, and the generated reaction force is lower, so that the above problems need to be solved by the booster ring 102b, as described in detail in embodiment 3.
Further to the necessity of the seal assembly 103 to work in conjunction with the rotary support assembly 101: the fixed seat 101a is provided with the circular groove 101a-1, the back of the fixed seat 101a is provided with the round platform 101e, the end face of the round platform 101e is provided with the interface 101e-1, the interface 101e-1 is connected with the gas pipe 201, the gas pipe 201 radially penetrates out along the fuel mixing pipe 200, the round platform 101e is connected with the support 101f, the support 101f is radially arranged, the tail end of the support 101f is fixedly connected with the outer side wall of the boosting ring 102b, and as the turntable 101b needs to rotate relative to the fixed seat 101a, a gap is necessarily formed between the turntable 101b and the fixed seat 101a, and under the condition that the spraying pressure of the scattering pipe 102a is required, the gas inlet leakage caused by the gap is obviously unfavorable for maintaining the rotation of the scattering pipe 102a, so that the good sealing effect between the turntable 101b and the fixed seat 101a is not influenced by the rotation of the turntable 101b is realized through the sealing component 103, and details are shown in the embodiment 2.
Embodiment 2, referring to fig. 3 and 5 to 10, is a second embodiment of the present invention, unlike the previous embodiment, the embodiment provides a rotary support assembly 101 and a seal assembly 103 of a fuel gas distribution pipe of a catalytic cracking unit regenerator, which realize rotary support of a rotary dispersion assembly 102, and solve the sealing problem between a fixed member and a movable member of the rotary support assembly 101 when the rotary dispersion assembly 102 is in a high-speed rotation state, and includes a turntable 101b, the turntable 101b is sleeved in a circular groove 101a-1, the turntable 101b is provided with a short pipe 101d along an axial direction thereof, a bearing 101c is provided between the short pipe 101d and the fixed seat 101a, and the dispersion pipe 102a is connected with the short pipe 101d along a radial direction, and the dispersion pipe 102a is distributed in an annular array with respect to one end of the short pipe 101d far from the fixed seat 101a, and realizes a rotary basic function of the dispersion pipe 102a through the fixed seat 101a, the bearing 101c and the turntable 101 b.
Further, an outer sealing ring 103a is arranged at the edge of the circular groove 101a-1 of the fixing seat 101a, an inner sealing ring 103b is arranged at the edge of the rotary disc 101b, the inner sealing ring 103b is sleeved in the outer sealing ring 103a, a first protrusion 103a-1 and a second protrusion 103a-2 are arranged on the outer side of the outer sealing ring 103a, a third protrusion 103b-1 is arranged between the first protrusion 103a-1 and the second protrusion 103a-2 on the inner side of the inner sealing ring 103b, and a guide ring 103c is sleeved in each of the first protrusion 103a-1, the second protrusion 103a-2 and the third protrusion 103 b-1.
The sealing component 103 of the device is a new application to the deformation of the Tesla valve structure, and referring to fig. 8 and 10, unlike the existing Tesla valve, the existing Tesla valve has the biggest characteristics that the fluid flowing resistance in one direction is small without a moving part, and the flowing resistance is increased sharply in the opposite direction, however, in the sealing component 103 of the device, the structural characteristics of the Tesla valve are only provided on the assembly structure of the section profile, and the sealing component 103 is a set of annular structures with moving parts, which are basically different from the existing Tesla valve, but have the performance characteristics of the Tesla valve;
the seal assembly 103 specifically works as follows: when gas is leaked outwards through a gap after entering between the fixed seat 101a and the rotary table 101b, the gas is required to pass through between the outer sealing ring 103a and the inner sealing ring 103b, and the concave-convex structure of the outer sealing ring 103a and the inner sealing ring 103b and the guide ring 103c between the outer sealing ring 103a and the inner sealing ring 103b form the structural characteristic that the section of the assembly structure is provided with a Tesla valve, so that the flowing resistance of the gas is extremely high, the higher the gas inlet pressure is, the higher the leakage resistance is, and meanwhile, the outer sealing ring 103a and the inner sealing ring 103b are not contacted, so that the rotation of the rotary table 101b relative to the fixed seat 101a is not influenced completely.
It should be noted that, referring to fig. 6, 7 and 9, the outer sealing ring 103a and the inner sealing ring 103b are connected with the corresponding guide ring 103c by means of local connection, so that the guide ring 103c is supported, as can be seen from fig. 9, the structural feature of the tesla valve is damaged at the connection position, and therefore, the volume of the connection portion should be reduced as much as possible.
The rest of the structure is the same as in embodiment 1.
In summary, the rotary support assembly 101 and the seal assembly 103 of the gas dispersion mechanism 100 realize the rotary support of the rotary dispersion assembly 102, and solve the sealing problem between the fixed member and the movable member of the rotary support assembly 101 when the rotary dispersion assembly 102 is in a high-speed rotation state.
Embodiment 3, referring to fig. 3 to fig. 5 and fig. 11, is a third embodiment of the present invention, and is different from the previous embodiment in that the embodiment provides a rotary dispersing assembly 102 of a fuel gas distribution pipe of a catalytic cracking device regenerator, which converts gas jet kinetic energy during dispersing fuel into mechanical energy for rotating a dispersing pipe 102a with higher efficiency, so that the dispersing pipe 102a rotates by itself while dispersing fuel gas without additional driving force input, and the rotary dispersing assembly comprises a dispersing pipe 102a, wherein a spray head 102c is arranged at the top end of the dispersing pipe 102a, the spray head 102c is provided with a pair of spray heads 102c, the spray heads 102c form a forty-five degree angle with the axial direction of the dispersing pipe 102a, the spray heads 102c are provided with tangential surfaces 102c-1 on two sides far away from each other, and the tangential surfaces 102c-1 are parallel to each other.
As can be seen from fig. 5 and 11, the distribution characteristics of the nozzles 102a-1 on the distribution pipe 102a, the closer the nozzles 102a-1 are to the outer end of the distribution pipe 102a, the smaller the distance between adjacent nozzles 102a-1, and the significance of this design is that, although the nozzles 102a-1 take a circular path, after the gas ejected from the nozzles 102a-1 moves along with other gases flowing in the fuel mixing pipe 200, the path is actually spiral, the closer the nozzles 102a-1 are to the outer end of the distribution pipe 102a, the longer the moving path is when rotating, the larger the distribution space range that needs to be covered, and the more sparse the gas spiral is ejected, so that by reducing the distance between the nozzles 102a-1 at the outer end of the distribution pipe 102a, the gas outlet amount at the outer end of the distribution pipe 102a is increased to solve the problem, so that the gas dispersing mechanism 100 disperses the gas with higher uniformity.
Specifically, the section profile of the boosting ring 102b is concave, guide vanes 102e are arranged in grooves of the boosting ring 102b, two groups of guide vanes 102e are distributed on two sides of the grooves of the boosting ring 102b, the guide vanes 102e are arranged in an annular array with respect to the boosting ring 102b, one end, which points to the outer side of the boosting ring 102b, of the guide vanes 102e is arranged along the radial direction of the boosting ring 102b, one end, which points to the center of the boosting ring 102b, of the guide vanes 102e is provided with a circular arc edge 102e-1, and the top ends of the dispersing pipes 102a and the spray heads 102c are sleeved in the boosting ring 102b and between the two groups of guide vanes 102 e.
As can be seen from fig. 4, the tangential plane 102c-1 has two main functions, namely, avoidance of air, avoiding rubbing between the nozzle and the guide vane 102e, enabling the nozzle to be closer to the guide vane 102e, reducing leakage of fuel gas between the nozzle and the guide vane 102e, slowing down pressure drop of fuel gas between the guide vane 102e and the nozzle, adjusting the fuel gas spraying direction of the nozzle, and matching with the position and angle design of the nozzle, so that fuel gas is sprayed between the guide vane 102e as much as possible, and the interaction between the fuel gas jet and the guide vane 102e is increased.
Further, the outer wall of the dispersion pipe 102a is provided with a baffle plate 102d along the radial direction thereof, the baffle plate 102d is arranged along the axial direction of the fuel mixing pipe 200, an included angle of forty-five degrees is formed between the baffle plate 102d and the axial direction of the dispersion pipe 102a, the baffle plate 102d is arranged at the inner side edge of the boosting ring 102b, the flow guiding plate 102e also folds back part of fuel gas to the dispersion pipe 102a through the end arc edge 102e-1, and additional thrust is generated on the dispersion pipe 102a through the folded-back air flow.
In summary, the reaction force generated by the blocking and refraction of the gas jet by the guide vane 102e is far higher than the reaction force generated by the injection of the gas jet in other gases, so that the distribution pipe 102a can operate at a higher rotation speed through the boosting ring 102b and the guide vane 102e, and the mixing effect of the gas in the fuel mixing pipe 200 is improved.
The rest of the structure is the same as in embodiment 2.
In summary, the rotating dispersion assembly 102 converts the kinetic energy of the gas injection during fuel dispersion into the mechanical energy of the rotation of the dispersion tube 102a with high efficiency, simplifies the structure of the device, reduces the cost and failure rate of the device, and realizes the rapid and uniform dispersion of the fuel gas in the fuel mixing tube 200.
