Description

[0002] Currently, many devices use steam, tail gas, and exhaust gas. In particular, low-pressure steam retains some pressure and heat after use, which will eventually be discharged through the exhaust pipe. At this time, the steam still has a pressure below 0.1 MPa and a temperature close to 100°C. This energy is lost as the steam is discharged. Traditional pneumatic motors are not suitable for energy recovery using this part of energy due to their own high noise, vibration, and low energy conversion efficiency. At the same time, since the output of this part of energy is not balanced, it is difficult to adapt to existing generator sets.

DETAILED DESCRIPTION
[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0029] Example 1
[0030] At present, many devices use steam, tail gas, and exhaust gas. In particular, low-pressure steam will have some residual pressure and heat after use, which will eventually be discharged through the exhaust pipe. At this time, the steam still has a pressure below 0.1 MPa and a temperature close to 100°C. This energy is lost in vain as the steam is discharged. Traditional pneumatic motors are not suitable for energy recovery due to their own high noise, vibration and low energy conversion efficiency. At the same time, since the output of this part of the energy is not balanced, it is difficult to adapt to the existing generator set. Therefore, Figure 1 As shown, an exhaust gas power generation pneumatic motor includes an outer shell 1, an upper shell 2, a rotating shaft 3, and a generator set 4. The outer shell 1 is cylindrical, the upper shell 2 is mounted on the outer shell 1 and fixed, the rotating shaft 3 is inserted into the outer shell 1 and passes through the outer shell 1, the rotating shaft 3 and the outer shell 1 are fixed and rotated, one end of the rotating shaft 3 is fixedly connected to the rotor end of the generator set 4 to drive the generator set 4 to generate electricity, and storage, transformation and conversion equipment are installed inside the generator set 4 for output and use to the outside.
[0031] The traditional pneumatic motor has a single-cylinder structure, so its amplitude is relatively large and it is unable to consume power, so it is noisy. At the same time, the friction of its own structure is limited and it will not consume too much power. Since the cylinder 5 in this solution is provided with multiple cylinders, the combined friction is relatively large, resulting in additional consumption exceeding the standard of the original design. Therefore, multiple low-friction bearings 10 are provided on the rotating shaft 3 in this solution. Through the combination of multiple low-friction bearings 10, the rotating shaft 3 will not consume too much energy when rotating, and then the limited capacity is converted into kinetic energy and electrical energy for storage. Specifically: Figure 2 As shown, the low friction bearing 10 is arranged between the plurality of cylinders 5 and embedded in the outer shell 1, replacing the direct contact between the rotating shaft 3 and the outer shell 1 and playing a supporting role.
[0032] like Figure 2 As shown, the upper shell 2 is fixedly mounted on the upper end of the outer shell 1, and the upper shell 2 and the outer shell 1 are fixed by bolts to make it a detachable structure. A plurality of circular cylinders 5 are arranged side by side in the outer shell 1, and a rotating wheel group 6 is provided in the cylinder 5 for receiving the incoming gas for working.
[0033] Specifically: the rotating wheel group 6 is fixed on the rotating shaft 3, and the rotating wheel group 6 includes a plurality of driving blades 9. In this scheme, considering improving efficiency and matching the frequency of gas entering, 8 driving blades 9 are provided to form a better circulating rotation dynamic structure. There is a fan-shaped area between the plurality of driving blades 9 to separate specific area areas. In order to reduce the kinetic energy wear problem of the driving blades 9 during rotation, the driving blades 9 in this scheme are made of carbon fiber material, which ensures the structural strength while reducing the mass of the structure. The low-friction bearing 10 can better drive the rotating shaft 3. The end of the driving blade 9 is in contact with the inner wall of the cylinder 5, which is used for sealing the area to prevent gas leakage and reduce the output value of the torque.
[0034] like Figure 1 As shown, an air intake group 7 is provided at the upper end of the upper shell 2 for connecting with external gas. The air intake group 7 is connected with multiple cylinders 5 through the upper shell 2. The function of the air intake group 7 is to input gas and finally exhaust gas. Specifically: the air intake group 7 includes an air intake pipe 11 and an air outlet pipe 12. The air intake pipe 11 is used for docking input, and the air outlet pipe 12 is used to exhaust the worked gas. A docking sleeve 13 is fixed between the air intake pipe 11 and the air outlet pipe 12 to help fixed docking. A channel is provided in the upper shell 2, and connecting ports are provided on the tops of the multiple cylinders 5. The channel is provided with two channels for collecting and discharging gas, and the two channels are respectively arranged near the left and right edges of the upper shell 2, leaving enough space to ensure the space of a single channel.
[0035] like Figure 2 As shown, an air distributor wheel 8 is rotatably connected in the channel for controlling multiple connection ports and controlling the order of gas entry. The air distributor wheel 8 is arranged in one of the channels, and the other channel is only responsible for collecting and discharging gas. The air inlet pipe 11 and the air outlet pipe 12 are respectively connected to the two channels for operation. The air distributor wheel 8 includes a rotating rod 14, an opening and closing ring 15, and a driving impeller 16. The rotating rod 14 is rotatably connected to the inner wall of the channel and crosses the entire channel. After the air inlet pipe 11 is discharged, it enters the channel. When passing through the channel, the driving impeller 16 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the opening and closing ring 15 to rotate to control the connection port.
[0036] Specifically: the opening and closing ring 15 and the driving impeller 16 are both sleeved on the rotating rod 14 and fixedly connected. There are four cylinders 5, and the four cylinders 5 are equidistantly arranged side by side. There are notches on the opening and closing ring 15, and the number of the opening and closing rings 15 is the same as the number of the cylinders 5. The opening and closing ring 15 is in a circular ring shape, and the notches on the four opening and closing rings 15 are equidistantly arranged with a difference of 90 degrees. The opening and closing ring 15 is arranged in contact with the inner wall of the channel. The rotation of the opening and closing ring 15 ensures that the connection port of each cylinder 5 is opened in turn, so that the gas enters the cylinder 5, and then the rotating shaft 3 is driven by driving the driving blade 9. Since the opening and closing ring 15 opens the cylinder 5 in turn, the cylinder 5 works in turn, so that the rotating shaft 3 is always kept rotating at a certain speed, and then the power generation group 4 is used to perform power generation and energy storage operations.
[0037] Example 2
[0038] Since the surface of the driving blade 9 is in the shape of a long strip and the order of contacting the gas is different, the rotating shaft 3 is at the farthest end of the driving blade 9. Therefore, the torque at the end of the driving blade 9 farthest from the rotating shaft 3 is the largest. Since the gas contacts the driving blade 9 as a whole to drive the rotating shaft 3, the torque at the farthest end of the driving blade 9 is the largest. As the distance to the rotating shaft 3 increases, the torque decreases, so the workmanship efficiency will be relatively reduced.
[0039] Therefore, Figure 4-6 As shown, a fixedly connected partition membrane 17 is provided between the driving vanes 9. The partition membrane 17 is made of plastic material. The rear half of the driving vane 9 is separated by the partition membrane 17. The partition membrane 17 is in an arc shape. One end of the partition membrane 17 is fixed to the top of one of the driving vanes 9, and the other end of the partition membrane 17 is fixed to the midpoint of the adjacent driving vane 9. The width of the partition membrane 17 is the same as that of the driving vane 9. Therefore, the gas can only act on the front half of the driving vane 9. Therefore, the efficiency of the working torque is the highest, thereby improving the rotation efficiency of the rotating shaft 3.
[0040] Example 3
[0041] Since the source of gas has uncertain stability, its input cannot be controlled, which may easily lead to unstable internal operation of the cylinder 5. In order to ensure that the internal circulation of the cylinder 5 can maintain good stability.
[0042] like Figure 7-9As shown, the middle part of the intake pipe 11 is cut off and fixedly connected with a rubber bag 18, the rubber bag 18 is cylindrical, and the outer cover of the rubber bag 18 is provided with a limit shell 19. The intake pipe 11 is threadedly connected with a limit sleeve 20, and the lower end of the limit sleeve 20 extends to the inside of the limit shell 19. Therefore, when the gas pressure is too high, the rubber bag 18 expands and stores a part of the gas, so that the gas input into the cylinder 5 maintains a certain range of pressure to prevent excessive fluctuations in the gas pressure causing excessive fluctuations in the rotation of the driving vane 9 inside the cylinder 5. At the same time, the expansion range of the rubber bag 18 is limited by controlling the limit sleeve 20, and then the pressure control range of the rubber bag 18 is adjusted to improve the stability of the operation of the driving vane 9 in the cylinder 5.
[0043] Although the terms such as outer shell 1, upper shell 2, rotating shaft 3, generator set 4, cylinder 5, rotating wheel set 6, air intake set 7, air distributor 8, driving blade 9, low friction bearing 10, air intake pipe 11, air outlet pipe 12, docking sleeve 13, rotating rod 14, opening and closing ring 15, driving impeller 16, separation membrane 17, rubber bag 18, limiting shell 19, limiting pipe sleeve 20 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
