Referring to the attached drawings 1-4, the mine return air complementary energy recycling system comprises a fan 1, an air duct 2, a turbine 3, a generator 4, a support 5, a slide 6, a propelling device 7 and a controller 8.
An air inlet of the fan 1 is communicated with an air return channel of a mine, an air outlet of the fan 1 is fixedly connected with an air inlet side of the air guide cylinder 2, a generator 4 is installed in the direction of an air exhaust side of the air guide cylinder 2, and the turbine 3 is located between the air guide cylinder 2 and the generator 4 and is installed on an input shaft of the generator 4. The air duct 2 is trumpet-shaped, the mouth end of the air duct is provided with a fan 1, and the open end of the air duct is arranged towards the turbine 3. The axial lead of the air duct 2 and the axial lead of the fan 1 are in the same straight line. The axial lead of the fan 1 and the axial lead of the generator 4 are in the same straight line. The turbine 3 is a device that rotates when blown by wind, and includes, but is not limited to, a turbine, a propeller, and a fan blade. In the present invention, the diameter of the turbine 3 is smaller than the diameter of the open end of the air guide duct 2. As shown in fig. 3, the turbine 3 is located in the open end of the air guide duct 2. The generator 4 is mounted on the bracket 5. Further, the bracket 5 is a sliding bracket, the lower end of the sliding bracket is mounted on the slideway 6, and the pushing device 7 is included, wherein the pushing device 7 is connected with the sliding bracket and used for pushing the sliding bracket to move towards the direction close to or far away from the air guide cylinder 2; the slide 6 is fixed on the foundation. The slideway 6 is provided with a rectangular chute which is used as a walking track of the sliding support. The slideway 6 is arranged in parallel with the axial lead of the generator 4. Further, the bottom of the sliding support is provided with a pulley. The generator 4 is electrically connected with a power supply network through devices such as a cable, a rectifier, a charger, a storage battery, an inverter and the like matched with the generator. The controller 8 is respectively electrically connected with the fan 1 and the propulsion device 7. The propulsion device 7 comprises a driving part 71 and an executing part 72, wherein the power output end of the driving part 71 is connected with the executing part 72; the driving part 71 provides power to drive the executing part 72 to rotate or move horizontally. In this embodiment, the driving member 71 is a driving motor, and the actuator 72 is a screw. Of course, the drive motor may also be supplied with power by the generator 4.
In one embodiment of the mine return air waste energy recycling system of the present invention, when the fan 1 is started, the controller 8 firstly controls the propulsion device 7 to retract, drives the generator 4 and the turbine 3 to move to the farthest position away from the air duct 2 by the sliding support, then the controller 8 powers on the fan 1 to start, at this time, because the distance between the turbine 3 and the air duct 2 is far, and the resistance of the air outlet is minimum when the fan 1 exhausts air through the air duct 2, the starting load of the fan 1 is minimum, the air exhaust volume of the fan 1 reaches the maximum value after the fan 1 is started to reach the rated rotating speed, then the controller 8 controls the propulsion device 7 to propel the sliding support to the direction close to the air duct 2, the sliding support drives the generator 4 and the turbine 3 to gradually close to the air duct 2, at the moment, mine return air discharged by the fan 1 blows the turbine 3 to rotate through the air duct 2, and then drives the generator 4 to generate electricity. With the further propulsion of the propulsion device 7, the closer the distance between the turbine 3 and the air guide duct 2 is, so that the mine return air blows the turbine 3 to rotate faster and faster, and the larger the electric energy generated by the generator 4 is; meanwhile, the resistance of the turbine 3 to the air exhaust of the fan 1 is gradually increased, the air exhaust amount of the fan 1 is reduced, and the mine return air amount is gradually reduced. When the distance between the turbine 3 and the air duct 2 reaches a certain position and the real-time exhaust volume of the fan 1 is consistent with the return air volume required by a mine, the controller 8 sends an instruction to the propulsion device 7 to stop propulsion and fix the position of the sliding support 5, so that the fan 1, the turbine 3 and the generator 4 stably operate. When the controller 8 is powered on and started to the fan 1, a frequency converter or a soft starter is adopted for starting, and the starting mode is a better starting mode. The real-time exhaust air volume and the mine return air volume of the fan 1 can be collected by adopting an air speed sensor, and the air speed sensor is electrically connected with the controller.
In another embodiment, as shown in fig. 3, the propulsion device 7 can push the sliding bracket to make the turbine 3 on the generator 4 enter the opening of the air guide duct 2, at this time, the kinetic energy obtained by the turbine 3 from mine return air is the largest, the rotating speed is the fastest, and the power generation amount of the generator 4 reaches the maximum.
In another embodiment, when the fan 1 stops operating, the controller simultaneously sends a retraction command to the propulsion device 7, so that the propulsion device 7 drives the sliding support, the generator 4 and the turbine 3 to move to the point farthest from the air duct 2 and fix the points.
In another embodiment, when the fan 1 needs to be started to run reversely (mine wind reversal), the sliding bracket, the generator 4 and the turbine 3 are located at the farthest point from the air guide duct 2 and do not rotate, the controller 8 controls the fan 1 to directly run reversely, the turbine 3 does not rotate, and the generator 4 does not generate electricity.
The technical scheme of the utility model overcomes the defect that the ox horn-shaped diffuser in the prior art blocks wind, the wind guide cylinder of the utility model has no wind blocking part, and simultaneously, the axis of the wind guide cylinder and the axis of the fan are in the same straight line, so that the wind resistance is minimum; in the prior art, energy contained in mine return air is greatly wasted, and the energy in the mine return air is fully absorbed through the combined characteristic of a turbine and a generator, so that the energy utilization is maximized; the air quantity can be adjusted by adjusting the distance between the turbine and the air duct.
