Description

Technical Field

[0001] The present invention relates to the technical field of air energy power generation, and in particular to a composite device integrating air energy power generation with other energy systems. Background Art

[0002] Air energy power generation is a technology that uses air energy to convert into electrical energy. On the one hand, compressed air energy storage power generation is one of its main methods. During the low power load period, electrical energy is used to compress air and store it in specific containers or underground caves. When the demand for electricity increases, high-pressure air is released to drive the turbine to rotate, which in turn drives the generator to generate electricity. This method realizes the storage and reuse of electrical energy and can effectively regulate the balance of power supply and demand.

[0003] In the existing technology, air energy power generation mainly adopts the method of compressed air energy storage power generation. During the low electricity consumption period, the excess electricity is used to drive the air compressor to compress the air and store it in a specific container (such as underground caves, abandoned mines, gas tanks, etc.), so that the air is stored in a high-pressure state, realizing the conversion of electrical energy into air pressure energy. When the electricity consumption is at a peak or when power generation is needed, the high-pressure air is released to drive the turbine to rotate, which in turn drives the generator to generate electricity, and the air pressure energy is converted into electrical energy again.

[0004] However, in actual use, since air energy power generation has an air intake period and an air storage period, the generator will be idle due to the loss of air supply, which makes the efficiency of air energy power generation low. At the same time, since the air storage bin is directly connected to the generator, it is not convenient to switch to other energy supply devices to generate electricity during the idle period of air energy power generation. In view of this, we propose a composite device that integrates air energy power generation with other energy systems. Summary of the invention

[0010] Preferably, the right side of the compressor is connected to the filter through a pipeline, and the lower end of the heat exchanger is connected to the air storage bin through a pipeline. The air storage bin is located at both ends of the underground main air inlet pipe and is respectively connected to two sets of branch pipes.

[0011] Preferably, rectangular through holes are provided at both upper and lower ends of the main air intake pipe, multiple groups of one-way valves are provided, and the multiple groups of one-way valves are respectively located at the connection junctions of the main air intake pipe and the branch pipe, and a through hole is provided at the center of the inner surface of the impeller.

[0012] Preferably, a plurality of groups of inclined arc blades are arranged on the outer arc surface of the impeller, a plurality of groups of bristles are arranged on one end of the front brush plate close to the one-way valve, the connecting frame is arranged in a circular ring shape as a whole, and the outer surface of the scraper is in contact with the one-way valve.

[0013] Preferably, the lower end of the motor is fixedly connected to the main intake pipe through a mounting bracket, the output shaft of the motor is connected to the main intake pipe piston, the inner arc surface area of ​​the baffle is larger than the surface area of ​​the rectangular through holes at the upper and lower ends of the main intake pipe, and the inner surface of the movable plate is provided with multiple groups of penetrating through holes.

[0016] Preferably, the upper end of the collecting bin is configured to be a flat-topped pyramid, the lower end of the collecting bin is provided with a through hole, and the lower end of the collecting tube is connected to an external collecting device.

[0017] Working principle: When this device is used, a compressor is needed to compress the intake air and store the air discharged from the compressor in the air storage bin. When air energy power generation is required, the gas stored in the air storage bin needs to be discharged and the temperature of the exhaust air is maintained through a heat exchanger. At the same time, the flowing air will also drive the impeller to rotate during the movement. When the impeller rotates, it will simultaneously drive the rotating shaft to rotate. When the rotating shaft rotates, it will simultaneously drive the connecting frame, scraper, and front brush plate to start rotating. During the rotation of the front brush plate, the surface of the one-way valve is brushed to avoid the subsequent air energy power generation effect affected by impurities remaining during thermal power generation and hydropower generation. When the air inside the air storage bin is insufficient, a compressor can be used to replenish the gas in the air storage bin, and any set of valves can be opened to perform thermal power generation or hydropower generation. At this time, the power generation medium entering the main air intake pipe will be blocked by the one-way valve and cannot enter other branch pipes or the left side of the main air intake pipe. The power generation medium will also drive the impeller to rotate and execute the cleaning instruction.

[0018] At the same time, in order to ensure the filtration of different power generation media during the operation of the generator of this device, sieve plates of different materials and mesh sizes are required. At this time, the motor can be started according to the actual power generation medium. When the motor moves, it will push the movable plate up and down, and stop moving when the designated sieve plate completely enters the main intake pipe. At this time, the sealing strip will maintain the sealing inside the main intake pipe, and prevent impurities in the medium from entering the generator through the sieve plate. At the same time, during the rotation of the shaft, the rear brush plate will also be driven to rotate, and during the rotation of the rear brush plate, impurities on the surface of the sieve plate that may hinder the filtration effect will be brushed, thereby maintaining the filtration effect of the sieve plate for a longer period of time.

[0019] In addition, when the device is running, the heat exchanger will transfer the internal temperature to the heat exchange tube, and conduct heat through direct contact between the heat exchange tube and the main intake pipe, so as to maintain the temperature of the pipe between the main intake pipe and the generator end. At the same time, since the heat at the main intake pipe is relatively high at this time, a small amount of moisture entering the insulation sleeve will liquefy and adhere to the inside of the main intake pipe, thereby corroding the main intake pipe.

[0020] The present invention provides a composite device integrating air energy power generation and other energy systems. It has the following beneficial effects:

[0021] 1. The present invention can open any set of valves on both sides when the air storage bin is in the intake state by means of the valves, connecting frames, one-way valves, branch pipes, front brush plates, scrapers, impellers, rotating shafts, bearings and support rods. At this time, water or hot steam can be introduced into the generator for power generation by means of hydropower and thermal power generation. At the same time, after the medium enters the middle of the main air intake pipe, it will also drive the impeller to rotate, and the scrapers and front brush plates can clean the one-way valve to avoid residual impurities in the process of hydropower and thermal power generation affecting the subsequent air energy power generation.

[0022] 2. The present invention can start the motor according to the different media actually entering the generator and the different filtering effects of the sieve plate through the provision of sealing strips, rear brush plates, baffles, movable plates, sieve plates and motors, and drive the sieve plates in different areas of the surface of the movable plate to be located inside the main air intake pipe, thereby achieving filtering effects under different conditions.

[0023] 3. The present invention can maintain the temperature of the area between the main air intake pipe and the generator during thermal power generation and air power generation by means of the insulation sleeve, heat exchange tube, collection tube and collection bin, thereby avoiding the reduction of power generation efficiency due to temperature loss. At the same time, it also allows the small amount of water vapor generated when it is cooled and liquefied to be collected to avoid corrosion of the heat exchange tube.
