Description

Technical Field

[0001] This utility model relates to the field of air generator technology, and in particular to a generator heat energy recovery device. Background Technology

[0002] Air generators are used to produce clean, dry air that meets specific needs. Their air compressors are responsible for providing high-pressure gas, but the compression and subsequent cooling processes cause the gas to carry a lot of moisture, so it is necessary to dehumidify it through an adsorption component.

[0003] Currently, most adsorption components use fixed-fill particles. During long-term operation, the particles are prone to caking due to continuous moisture absorption and changes in physical state, which reduces the effective contact area and dehumidification efficiency. This necessitates frequent replacement of the adsorption components to maintain long-term dehumidification operation. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a generator heat energy recovery device, which converts the heat energy of the high-temperature gas generated by compression into mechanical power through a heat energy transmission component, driving the adsorption component to rotate continuously. This movement keeps the adsorption particles in a loose state, effectively avoiding the problem of caking caused by long-term static placement or particle moisture, maintaining the effective contact area between the particles and the airflow, thereby ensuring stable dehumidification effect.

[0006] To achieve the above objectives, the first aspect of this utility model provides a generator heat energy recovery device, comprising: an air generator body and a heat energy transmission assembly, wherein the air generator body includes a protective cover, an air compressor, an air storage tank, an aftercooler, an adsorption assembly, and an air outlet pipe, wherein the air compressor is fixedly installed on the top of the protective cover, the air storage tank is fixedly installed on the bottom of the air compressor and the two are interconnected, the aftercooler is fixedly installed on one side of the air storage tank, the air outlet pipe is fixedly installed on one side of the protective cover, the adsorption assembly is disposed between the aftercooler and the air outlet pipe, and the heat energy transmission assembly is disposed between the air storage tank and the aftercooler, and the heat energy transmission assembly is connected to the adsorption assembly.

[0007] In addition, the generator heat recovery device proposed above according to this utility model may also have the following additional technical features: Specifically, a first connecting pipe is installed on the side of the aftercooler opposite the exhaust pipe.

[0008] Specifically, the adsorption assembly includes a first rotating tube, a second rotating tube, and an adsorption cylinder, wherein the first rotating tube is rotatably connected to the outside of the first connecting tube, the second rotating tube is rotatably connected to the outside of the gas outlet tube, and the adsorption cylinder is fixedly installed between the first rotating tube and the second rotating tube.

[0009] Specifically, the heat transmission assembly includes a second connecting pipe, an insulation pipe, a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a shape memory alloy coil. A pressure regulating valve is installed at the top of the gas storage tank. The second connecting pipe is fixedly connected between the pressure regulating valve and the aftercooler. The insulation pipe is sleeved on the outside of the second connecting pipe. The first synchronous pulley is rotatably connected to the inside of the insulation pipe. The second synchronous pulley is fixedly installed on the outside of the first synchronous pipe. The synchronous belt is sleeved on the outside of the first and second synchronous pulleys. The shape memory alloy coil is fixedly installed on the outside of the synchronous belt.

[0010] Compared with the prior art, the present invention has the following advantages: By setting up a thermal energy transmission component, the heat energy of the high-temperature gas at the outlet of the gas storage tank is converted into mechanical power to drive the adsorption component to rotate continuously, so that the particles in the adsorption cylinder always remain in a dynamic and loose state, effectively avoiding the problem of caking caused by long-term static placement or moisture absorption, and maintaining the effective contact area and dehumidification efficiency of the particles.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] A generator heat recovery device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, an embodiment of the present invention provides a generator heat recovery device, comprising: an air generator body 1 and a heat transmission assembly 2.

[0022] The air generator body 1 includes a protective cover 11, an air compressor 12, an air tank 13, an aftercooler 14, an adsorption assembly 15, and an air outlet pipe 16. The air compressor 12 is fixedly installed on the top of the protective cover 11, and the air tank 13 is fixedly installed on the bottom of the air compressor 12. The two are connected to each other. The aftercooler 14 is fixedly installed on one side of the air tank 13, and the air outlet pipe 16 is fixedly installed on one side of the protective cover 11. The adsorption assembly 15 is disposed between the aftercooler 14 and the air outlet pipe 16.

[0023] The thermal energy transmission component 2 is disposed between the gas storage tank 13 and the aftercooler 14, and the thermal energy transmission component 2 is connected to the adsorption component 15.

[0024] It should be noted that the gas storage tank 13 described in this embodiment is equipped with a pressure regulating valve at its top, and the pressure regulating valve is connected to the aftercooler 14 through the heat energy transmission component 2.

[0025] In this embodiment, the aftercooler 14 is equipped with a first connecting pipe 141 on the side opposite to the exhaust pipe 16, and the adsorption assembly 15 is rotatably connected to the exhaust pipe 16 and the first connecting pipe 141 respectively.

[0026] Specifically, when technicians need to use this device to generate air, a generator heat recovery device is required.

[0027] First, the technician turns on the air compressor 12. The air compressor 12 compresses outside air into the air tank 13 through the air intake with a filter. The air temperature rises after compression.

[0028] Then, the technicians opened the pressure regulating valve, allowing the high-temperature gas in the gas storage tank 13 to be input into the aftercooler 14 through the heat energy transmission component 2. The high-temperature gas is cooled by the aftercooler 14 and becomes low-temperature humid air, which is then input into the adsorption component 15 for dehumidification. When the high-temperature gas passes through the heat energy transmission component 2, heat energy recovery is achieved, causing the heat energy transmission component 2 to drive the adsorption component 15 to rotate outside the outlet pipe 16 and the first connecting pipe 141, causing the adsorbed particles to move. After the humid air comes into full contact with the adsorbed particles for dehumidification, it is discharged through the outlet pipe 16.

[0029] Finally, the technicians connected the vent pipe 16 to the experimental instrument and began the experimental work.

[0030] In one embodiment of this utility model, such as Figures 2-6 As shown, the adsorption assembly 15 includes a first rotating tube 151, a second rotating tube 152, and an adsorption cylinder 153.

[0031] The first rotating tube 151 is rotatably connected to the outside of the first connecting tube 141.

[0032] It should be noted that a mechanical seal is provided at the rotational connection between the first rotating tube 151 and the first connecting tube 141 described in this example to prevent gas leakage.

[0033] The second rotating tube 152 is rotatably connected to the outside of the air outlet tube 16.

[0034] Understandably, a mechanical seal is provided at the rotatable connection between the second rotating pipe 152 and the outlet pipe 16 to prevent gas leakage.

[0035] The adsorption tube 153 is fixedly installed between the first rotating tube 151 and the second rotating tube 152.

[0036] Specifically, the first rotating tube 151 and the second rotating tube 152 are respectively installed with connecting flanges at their close ends, and the two ends of the adsorption cylinder 153 are also installed with corresponding flanges. The adsorption cylinder 153 is fixedly connected to the first rotating tube 151 and the second rotating tube 152 respectively through the flanges, and the mating flanges are equipped with sealing rubber rings to prevent gas leakage.

[0037] The heat transmission assembly 2 includes a second connecting pipe 21, an insulation pipe 22, a first synchronous pulley 23, a second synchronous pulley 24, a synchronous belt 25, and a shape memory alloy coil 26.

[0038] The second connecting pipe 21 is fixedly connected between the pressure regulating valve and the aftercooler 14, connecting the pressure regulating valve and the aftercooler 14.

[0039] The insulation pipe 22 is sleeved on the outside of the second connecting pipe 21, the first synchronous wheel 23 is rotatably connected to the inside of the insulation pipe 22, and the second synchronous wheel 24 is fixedly installed on the outside of the first rotating pipe 151.

[0040] The timing belt 25 is sleeved on the outside of the first timing pulley 23 and the second timing pulley 24, and the memory alloy coil 26 is fixedly installed on the outside of the timing belt 25.

[0041] Specifically, when the pressure regulating valve exhausts gas, high-temperature gas flows in the second connecting pipe 21, causing the second connecting pipe 21 to heat up. The heat preservation pipe 22 can preserve the temperature and reduce the rate of temperature loss. At this time, the technician needs to manually rotate the adsorption cylinder 153 in one direction to provide an initial rotational force for the adsorption cylinder 153, which also provides an initial direction of operation for the synchronous belt 25. The first synchronous wheel 23 rotates inside the heat preservation pipe 22, which heats the synchronous belt 25 and the shape memory alloy coil 26 outside the first synchronous wheel 23. This causes the shape memory alloy coil 26 to tighten in the high-temperature area. After detaching from the heat preservation pipe 22, the shape memory alloy coil 26 cools and lengthens. Under the initial operation of the synchronous belt 25, the shape memory alloy coil 26 actively contracts in the high-temperature area and passively extends in the low-temperature area. Combined with the characteristic that the contraction force of the shape memory alloy coil 26 is greater than the extension force, it forms a unidirectional tension on the synchronous belt 25, allowing the synchronous belt 25 to continue to operate, thereby driving the adsorption cylinder 153 to rotate and the adsorbed particles to move continuously.

[0042] In summary, the generator heat recovery device of this utility model can recover the high-temperature heat energy generated by air compression and convert it into mechanical power through the shape memory alloy coil 26. No additional energy is required, which helps to save energy. It can drive the adsorption component 15 to rotate, so that the adsorbed particles move continuously, improve the contact efficiency between humid air and adsorbed particles, reduce agglomeration, and reduce gas leakage due to the sealing design of each connection part. After initial drive, it can operate autonomously and is easy to operate.
