Description

Technical Field

[0001] The invention belongs to the technical field of heat recovery, and in particular relates to an ORC heat recovery system. Background Art

[0002] The ORC heat recovery unit is a device that uses organic working fluid to absorb heat under a low-temperature heat source and convert it into mechanical energy or electrical energy. It is mainly composed of components such as an evaporator, a turbine (or expander), a condenser and a working fluid pump. During the operation of the unit, the organic working fluid absorbs low-temperature waste heat in the evaporator and converts it into high-temperature and high-pressure steam, which then enters the turbine to expand and do work, driving the generator to generate electricity or dragging other power machinery. In the ORC heat recovery unit, especially in situations involving gas as a heat source (such as internal combustion engine exhaust, industrial waste gas, etc.), parameters such as air flow temperature, pressure and flow rate may alternate with changes in operating conditions. This alternating airflow will have a significant impact on the flow state inside the unit.

[0003] Surge is an unstable flow phenomenon that usually occurs in rotating machinery such as turbines and compressors. When the airflow parameters change dramatically, it may cause the airflow inside the turbine to produce periodic unstable flow, which in turn causes mechanical vibration, increased noise, and even equipment damage.

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figures 1 to 14 The present invention provides a technical solution: an ORC heat recovery system, comprising a substrate 1 and an evaporator 2, a turbine 3, a condenser 4, a working fluid pump 5 and an exhaust port 34 arranged on the substrate 1, the turbine 3 is located above the evaporator 2, an exhaust assembly is arranged at one end of the turbine 3, a shock-absorbing and silencing hose or a flow-blocking silencer is arranged at one end of the exhaust assembly, a composite device 6 is fixedly connected between the evaporator 2 and the turbine 3, the interior of the composite device 6 includes a noise reduction component and an absorption component, the absorption component includes two groups of receiving assembly components, and the two groups of receiving assembly components each include two groups of deformable legs and a resistance component Each group of deformable legs includes two protrusions 9, and a round rod 11 is fixedly connected to the outer walls of the two protrusions 9 on the side close to each other, and the same round rod 2 13 is fixedly connected between the two round rods 11, and a combination block 15 is slidably connected to the outer walls of the two round rods 11, and a straight spring 12 is fixedly connected between the combination block 15 and the protrusion 9. A linkage component is arranged between the deformable legs and the resistance component, and the linkage component includes a connecting plate 16 and a connecting plate 2 19. A fastener is arranged inside the composite device 6, and the connecting plate 16 and the connecting plate 2 19 are in a rotational connection relationship with the same fastener. When the air flow parameters passing through the turbine 3 change dramatically, the air flow inside the turbine 3 may produce periodic unstable flow, and the downward shaking tendency of the turbine 3 will be transmitted to the composite device 6 closely attached thereto. Through the provided absorption components and noise reduction components, each cross bar 18 and short bar 2 are moved downward, and each straight spring 12 is compressed. Under the action of the spring damping member 10, the vertical downward external force is transmitted to the horizontal direction, thereby reducing the external force and absorbing the vibration. At the same time, the sound insulation sponge is further compressed to increase the density, absorb the noise generated during the vibration, and reduce the possibility of damage.

[0036] For example 2, please refer to Figures 1 to 14On the basis of the first embodiment, the composite device 6 has two arc-shaped outer walls, which are respectively matched with the outer walls of the turbine 3 and the evaporator 2. The combination block 15 includes a moving block and two support plates. The two top ends of the two support plates are both chamfered, and the two support plates are fixedly connected to the top of the moving block. The positions of the two support plates are far away from each other and symmetrically distributed. A short rod 1 is fixedly connected between the two support plates. The short rod 1 passes through one end of the connecting plate 16 and the two are in a rotational connection relationship. The fastener includes two convex plates 17 and a short rod 2 that are far away from each other. The short rod 2 passes through the other end of the connecting plate 16 and the two are in a rotational connection relationship. The straight spring 12 is specifically fixedly connected between the moving block and the convex block 9. The straight spring 12 is sleeved and slidably connected to the outer wall of the round rod 11. The bottom end of each moving block is fixedly connected with a stop block 14, and a spring damper 10 is arranged between each stop block 14 and the convex block 9, wherein a cross bar 18 is rotatably connected between the two convex plates 17, and the cross bar 18 is located between the two short bars 2. The outer wall of the cross bar 18 passes through one end of the connecting plate 2 19, and the linkage assembly is slidably connected with the round rod 2 13, and the other end of the connecting plate 2 19 passes through and is rotatably connected with the cross bar 2, and the two ends of the cross bar 2 respectively pass through the two sides of the connecting plate 2 19 and are rotatably connected with the transfer block 20, and the two transfer blocks 20 are respectively slidably connected to the outer walls of the two round rods 2 13, and each transfer block The bottom end of 20 is fixedly connected with a connecting block 21, one end of the connecting block 21 is fixedly connected with an extrusion block 22, an opening 23 is opened in the middle of the extrusion block 22, and the cross section of the extrusion block 22 and the cross section of the opening 23 are both right-angled trapezoids. The inner wall of the composite device 6 is provided with a slot 7. The noise reduction component includes 33 and a sound insulation sponge filled between 33 and the inner cavity of the composite device 6. The bottom end of 33 is fixedly connected to the top of each convex plate 17. The inside of the composite device 6 is fixedly connected with a receiving block 8. A rectangular space is formed between the receiving block 8 and the partition 30. The two groups of receiving assembly components are Arranged inside the space of this rectangular parallelepiped, the top of the receiving block 8 is provided with two grooves 27 which are symmetrically positioned and far away from each other, the inside of the groove 27 is slidably connected with a straight block 26, the top of the straight block 26 is fixedly connected with an extrusion block 24, the cross-section of the extrusion block 24 is composed of an isosceles trapezoid and a rectangle, the overall width of the extrusion block 24 is larger than the opening 23 and smaller than the width of the extrusion block 1 22, the bottom end of the straight block 26 is provided with a groove 28, the groove 28 is generally in the shape of a cylinder without a bottom surface, and a straight spring 29 is fixedly connected between the top of the inner wall of the groove 28 and the bottom of the inner wall of the groove 27.

[0037] When the air flow parameters passing through the turbine 3 change dramatically, the air flow inside the turbine 3 may produce periodic unstable flow, and the tendency of the turbine 3 to shake downward will be transmitted to the composite device 6 closely attached thereto. The arc-shaped outer wall of the composite device 6 that fits the turbine 3 has a tendency to deflect downward, which will be synchronously transmitted to each fastener through the slot 17 and the partition 30. Then the fastener moves downward, and the connecting plate 16 and the connecting plate 2 19 that are set by rotation are rotated at the same time, and rotate around the short rod 1 and the short rod 2, the cross bar 18 and the cross bar 2 respectively. The deflection of the connecting plate 16 causes the combination block 15 to get closer and closer to the protrusion 9, and the straight spring 12 between the two is compressed. Under the action of the spring damping member 10, this external force is gradually absorbed. Since the force is mutual, the straight spring 12 will gradually rebound. At the same time, the two The deflection of the connecting plate 2 19 and the connecting action of the two connecting blocks 21 will cause the distance between the two extrusion blocks 1 22 to be shortened, and the extrusion block 24 located between the two will be subjected to extrusion forces from both ends at the same time. Since the contact ends of the extrusion blocks 1 22 and 24 are both inclined, the extrusion block 24 will be squeezed along with the extrusion block 1 22 and move up along its inclined end. Then, the top plate 25 will resist the partition 30 before the straight spring 12 reaches the compression limit. It cooperates with the spring damping member 10 and the straight spring 12 to reduce the external vibration again at the same time. In the process of the top plate 25 resisting the partition 30, affected by the length of the two connecting blocks 21, the top plate 25 will continue to squeeze the sound insulation sponge filled between the partition 30 and the inner cavity of the composite device 6 to increase the density, absorb the noise generated during vibration, and reduce the possibility of damage.

[0038] For example 3, please refer to Figures 1 to 14 On the basis of the second embodiment, each end of the side of the straight block 26 is chamfered, the contact end of the extrusion block 1 22 and the straight block 26 is also chamfered, a top plate 25 is provided at the top of the extrusion block 24, and spherical grooves 31 are provided at the two inclined ends of the extrusion block 24 and the inclined ends of the two extrusion blocks 1 22, and a ball 32 is rollingly connected inside each spherical groove 31.

[0039] The chamfered extrusion block 22 and the straight block 26 make the contact between the opening 23 and the straight block 26 smoother, avoiding bumps and jams that would cause inconvenience in linkage. Through the spherical grooves 31 and the balls 32, when the extrusion block 24 moves up along the inclined end of the extrusion block 22, the balls 32 on the extrusion block 24 and the balls 32 on the extrusion block 22 will contact each other and produce a certain impact, which will change the friction mode between the extrusion block 24 and the inclined end of the extrusion block 22, changing the sliding friction into rolling friction, thereby reducing the friction force that needs to be overcome during the change process. This allows a tiny external vibration to easily drive the extrusion block 24 to move up, thereby correspondingly reducing the external vibration force, and more quickly squeezing the sound insulation sponge filled between the partition 30 and the inner cavity of the composite device 6, thereby increasing the density, absorbing the noise generated during vibration, and reducing the possibility of damage.

[0040] Example 4, please refer to Figures 1 to 14 On the basis of the first embodiment, the shock-absorbing and silencing hose includes an intermediate pipe assembly 2 362 and two pressure-bearing steel barrels 2 352. The positions of the two pressure-bearing steel barrels 2 352 are relatively arranged. Both ends of the two pressure-bearing steel barrels 2 352 are fixedly connected with joints 42. One end of one of the joints 42 is movably connected with 411. An intermediate pipe assembly 2 362 is arranged between the two joints 42 located at the central position. One end of each joint 42 is clamped with a groove flange 43. The exhaust ports 34, 41 1 and the grooved flange 43 can be assembled together and screwed together with a plurality of bolts arranged equidistantly. The joint 42 is clamped between the grooved flange 43 and the rectifying pipe 41. The two grooved flanges 43 located in the central position are screwed together by a plurality of bolts arranged equidistantly. A muffler 38 is arranged at one end of the joint 42 far from the exhaust port 34. A support seat 39 is arranged between the muffler 38 and 1. A pull rod assembly 2 372 is arranged between the two grooved flanges 43 with the farthest horizontal spacing. The flow silencer includes an intermediate pipe assembly 361 and two pressure-bearing steel barrels 351. The length of the intermediate pipe assembly 361 is greater than that of the intermediate pipe assembly 2 362. The positions of the two pressure-bearing steel barrels 351 are relatively arranged. Two joints 42 are respectively fixedly connected to the two ends of the two pressure-bearing steel barrels 351. One end of one of the joints 42 is movably connected with 412. An intermediate pipe assembly 361 is arranged between the two joints 42 located in the central position. Each groove flange 43 is respectively clamped at one end of the joint 42. The outer wall of the intermediate pipe assembly 361 is fixedly connected to two symmetrically distributed annular blocks 33. The annular blocks 33 and the groove flanges 43 are screwed by bolts. The rest of the configuration of the flow-blocking silencer is the same as that of the vibration-absorbing silencer hose. A pull rod assembly 371 is arranged between the two groove flanges 43 with the farthest horizontal spacing. The inner walls of the pressure-bearing steel barrel 351, the pressure-bearing steel barrel 2 352, the intermediate pipe assembly 1 361 and the intermediate pipe assembly 2 362 are all provided with pulsation buffer wire mesh 40.

[0041] It should be noted here that: when the pump outlet medium (R134a and R245fa) is running, there will be vibration and noise caused by kicking flow. The design temperature is 110-134℃ and 85-110℃. When the pump outlet medium passes through the exhaust port 34, it will vibrate. The shock-absorbing and silencer hose and the choke silencer are installed according to the different powers of the unit to solve this problem. The two are not installed at the same time. The shock-absorbing and silencer hose and the choke silencer use different media and have different pressures. The relatively arranged pressure-bearing steel barrel 1 351 and pressure-bearing steel barrel 2 352 provide good flexibility and shock-absorbing capabilities to effectively withstand internal pressure. The design incorporates the silencer 38, as well as the fitting assembly method with the exhaust port 34 and other components. The structure such as the grooved flange 43 fastened by bolts effectively reduces the noise generated during the flow of air or liquid, and improves the quiet performance of the equipment. The modular design is adopted, such as the intermediate pipe assembly 1 361 and the intermediate pipe assembly 2 362, the pressure steel barrel 1 351, the pressure steel barrel 2 352, the joint 42 and the groove flange 43 and the bolts and other components, which are convenient for disassembly and assembly, and are conducive to the daily maintenance and troubleshooting of the equipment. The various components are tightly connected by fasteners such as bolts, especially the screw connection between the groove flange 43 and the rectifier pipe 41, the annular block 33, etc., which enhances the overall stability and durability of the structure. The pulsation buffer wire mesh 40 arranged on the inner wall can further absorb and disperse the energy generated by the fluid pulsation, reduce the pressure fluctuation inside the system, and improve the stability and operation efficiency of the system. There are many holes on the conical barrel for gas rectification. By using a shock-absorbing and silencing hose or a flow-blocking silencer, combined with the silencer 38, the noise is reduced to 4-6mm / s and the audio is reduced by 11-14db.

[0042] In actual use, when the air flow parameters passing through the turbine 3 change dramatically, the air flow inside the turbine 3 may produce periodic unstable flow, and the tendency of the turbine 3 to shake downward will be transmitted to the composite device 6 closely attached thereto. The arc-shaped outer wall of the composite device 6 that fits the turbine 3 has a tendency to deflect downward, which will be synchronously transmitted to each fastener through the slot 17 and the partition 30. Then the fastener moves downward, and the connecting plate 16 and the connecting plate 2 19 that are arranged are rotated at the same time and respectively rotate around the short rod 1 and the short rod 2, the cross bar 18 and the cross bar 2. The deflection of the connecting plate 16 causes the combination block 15 to get closer and closer to the protrusion 9, and the straight spring 12 between the two is compressed. Under the action of the spring damping member 10, this external force is gradually absorbed. Since the force is mutual, the straight spring 12 will gradually rebound. At the same time, When the two connecting plates 19 are bent and the connecting action of the two connecting blocks 21 is applied, the distance between the two extrusion blocks 22 is shortened, and the extrusion block 24 located between the two is subjected to extrusion forces from both ends at the same time. Since the contact ends of the extrusion blocks 22 and 24 are inclined, the extrusion block 24 will be squeezed along with the extrusion block 22 and move up along its inclined end. Then, the top plate 25 will resist the partition 30 before the straight spring 12 reaches the compression limit. It cooperates with the spring damping member 10 and the straight spring 12 to reduce the external vibration again at the same time. In the process of the top plate 25 resisting the partition 30, affected by the length of the two connecting blocks 21, the top plate 25 will continue to squeeze the sound insulation sponge filled between the partition 30 and the inner cavity of the composite device 6 to increase the density, absorb the noise generated during vibration, and reduce the possibility of damage.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
