[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1-Figure 10 As shown, the present invention provides a steam engine, including a chassis 1, an oil-free air compressor body 2 arranged in the chassis 1, an air intake air filter system, a waste heat recovery system, an atomization system, and a water supply system.

[0026] The oil-free air compressor body 2 is provided with an air compressor air inlet, an air compressor exhaust port, an air compressor hot oil outlet and an air compressor cold oil inlet. The air compressor air inlet is connected to the outlet of the air compressor air inlet pipe 3, the air compressor exhaust port is connected to the inlet of the air compressor exhaust pipe 4, the air compressor hot oil outlet is connected to the inlet of the air compressor oil outlet pipe 5, and the air compressor cold oil inlet is connected to the outlet of the air compressor return oil pipe 6.

[0027] The air intake air filter system includes a labyrinth air filter box 7, in which a labyrinth air filter channel 8 is provided. The chassis 1 is provided with a chassis air inlet 9, and the chassis air inlet 9 connects the outside of the chassis 1 and the inlet of the labyrinth air filter channel 8. The outlet of the labyrinth air filter channel 8 is connected to the inlet of the air compressor intake pipe 3.

[0028] The waste heat recovery system includes a waste heat recovery device 10, which is provided with a waste heat oil inlet, a waste heat oil outlet, a waste heat water inlet and a waste heat water outlet. The waste heat oil inlet is connected to the outlet of the air compressor oil outlet pipe 5, the waste heat oil outlet is connected to the inlet of the air compressor return oil pipe 6, the waste heat water outlet is connected to the inlet of the water pump 12 through the first water outlet pipe 11, and the outlet of the water pump 12 is connected to the inlet of the water heater 14 through the second water outlet pipe 13.

[0029] The atomization system includes an atomization heater 15, which has an atomization heating chamber, in which a heating core is provided, and two ends of the atomization heater 15 are respectively provided with a hot air inlet and a steam outlet connected to the atomization heating chamber, the hot air inlet is connected to the outlet of the air compressor exhaust pipe 4, and the steam outlet is connected to the steam use end through a steam discharge pipe 16. The atomization heater 15 is also provided with at least one atomization humidifier 17, which is located between the hot air inlet and the steam outlet, one end of the atomization humidifier 17 extends into the atomization heating chamber and is provided with a multi-point humidification nozzle, and the other end of the atomization humidifier 17 is connected to the outlet of the water heater 14 through a third water outlet pipe 18.

[0030] The water supply system includes a water softener 19, the outlet of the water softener 19 is connected to the inlet of a descaling device 21 through a first water inlet pipe 20, the outlet of the descaling device 21 is connected to the inlet of a precision filter 23 through a second water inlet pipe 22, and the outlet of the precision filter 23 is connected to the waste heat water inlet through a third water inlet pipe 24.

[0031] The steam outlet is provided with a first temperature sensor and a hygrometer, and the first temperature sensor, the hygrometer, the water pump 12, the water heater 14 and the heating core are all connected to the controller.

[0032] When the present invention is in use, external air enters the labyrinth air filter channel 8 from the chassis air inlet 9, and after being filtered through the labyrinth air filter channel 8, enters the oil-free air compressor body 2 from the air compressor air inlet pipe 3 and the air compressor air inlet. The oil-free air compressor body 2 compresses the air and outputs oil-free high-temperature compressed air, and the oil-free high-temperature compressed air enters the atomization heating chamber of the atomization heater 15 through the air compressor exhaust port, the air compressor exhaust pipe 4 and the hot air inlet. The hot oil in the oil-free air compressor body 2 enters the oil circuit of the waste heat recovery device 10 through the air compressor hot oil outlet, the air compressor oil outlet pipe 5 and the waste heat oil inlet for heat exchange, and the hot oil becomes cold oil. The oil circuit of the waste heat recovery device 10 recovers the heat of the hot oil and transfers it to the water circuit therein, so that the cold water in the water circuit is heated, waste heat recovery is achieved, and energy utilization is improved. The cold oil returns to the oil-free air compressor body 2 again through the waste heat oil outlet, the air compressor oil return pipe 6 and the air compressor cold oil inlet. The water softener 19 softens the cold water to reduce the hardness of the water and prevent scaling of the pipelines. The cold water then enters the descaling device 21 through the first water inlet pipe 20, and the descaling device 21 descales the cold water. The cold water then enters the precision filter 23 through the second water inlet pipe 22, and the precision filter 23 filters various impurities and suspended matter in the cold water. The cold water is softened, descaled, and filtered before entering the waste heat recovery device 10 to ensure that the water quality meets the standard. Then the cold water enters the water path of the waste heat recovery device 10 through the third water inlet pipe 24 and the waste heat water inlet. The cold water is heated through heat exchange. Then the warm water enters the water pump 12 through the waste heat water outlet and the first water outlet pipe 11. The water pump 12 provides power for the later atomization. The water pump 12 pumps the warm water into the water heater 14 through the second water outlet pipe 13. The water heater 14 continues to heat the warm water. The heated hot water is transported to the atomizing humidifier 17 through the third water outlet pipe 18. Then, atomized water is sprayed into the atomizing heating chamber of the atomizing heater 15 through the multi-point humidifying nozzle of the atomizing humidifier 17. The atomized water is close to the gas state and is easily mixed with the high-temperature compressed air in the atomizing heating chamber. It is heated by the heating core to form steam with a certain humidity, temperature and pressure. Then the steam is transported to the steam use end (i.e., the steam setting equipment for textile products) through the steam outlet and the steam exhaust pipe 16.

[0033] The water pump 12 of the present invention is preferably a variable frequency pump, so that the amount of atomized water in the atomization system can be controlled, and thus the humidity of the steam can be controlled. Because the heat exchange of the waste heat recovery device is low, the water temperature needs to be close to the gaseous state before entering the atomization heating chamber, so it is necessary to heat the warm water to above 150°C through a water heater, so that the atomized water can be well mixed with the high-temperature compressed air. Affected by the exhaust temperature of the main body of the oil-free air compressor, the output steam temperature will fluctuate. Through the heating of the heating core, the steam temperature can reach above 210°C, ensuring that the temperature of the steam is accurately controllable. The first temperature sensor of the present invention can detect the temperature of the output steam, and then feed back the result to the controller. The controller can use the PID parameters to adjust the working condition of the heating core in real time, thereby achieving the effect of accurately controlling the steam temperature. The hygrometer of the present invention can detect the humidity of the output steam, and then feed back the result to the controller. The controller can adjust the working condition of the water pump 12 in real time, thereby achieving accurate control of the amount of atomized water and ensuring that the humidity of the steam is appropriate. The steam provided by the present invention has certain humidity, temperature and pressure, and replaces the steam provided by traditional boilers. The humidity is appropriate, and there will be no dripping during steam shaping, thereby ensuring the fiber opening and shaping effects of chemical fiber textile products, saving energy, being environmentally friendly, having a simpler process and more stable quality.

[0034] Preferably, the labyrinth air filter box 7 is provided with an air filter box air inlet 25, which is connected to the interior of the chassis 1 and the entrance of the labyrinth air filter channel 8, and the air filter box air inlet 25 is provided with a chute 26 on both sides, and a cover plate 27 covering the air filter box air inlet 25 is slidably provided in the chute 26, and the labyrinth air filter box 7 is provided with a driving mechanism, which drives the cover plate 27 to move in the chute 26 to control the position of the cover plate 27 covering the air filter box air inlet 25, and the labyrinth air filter channel 8 is provided with a second temperature sensor, which is connected to the controller. The hot air inside the chassis 1 can enter the labyrinth air filter channel 8 through the air filter box air inlet 25, and mix with the external cold air coming in from the chassis air inlet 9, so that the temperature in the labyrinth air filter channel 8 is suitable, which can improve the working efficiency of the oil-free air compressor body 2, and can also reduce the air temperature in the chassis 1, and have a heat dissipation effect. The second temperature sensor in the labyrinth air filter channel 8 can detect the air temperature in the labyrinth air filter channel 8 in real time and feed it back to the controller. The controller controls the operation of the driving mechanism according to the temperature, and then controls the cover plate 27 to move along the slide groove 26, so as to adjust the opening and closing size of the air filter box air inlet 25, and then controls the amount of hot air in the chassis 1 flowing into the labyrinth air filter channel 8, so as to control the air temperature in the labyrinth air filter channel 8, ensure that the air temperature in the labyrinth air filter channel 8 is appropriate, and the structure is simple and compact.

[0035] Preferably, the driving mechanism includes a motor 28, a gear is provided on the output end of the motor 28, and a rack 29 parallel to the chute 26 is provided on the cover plate 27, and the gear is meshed with the rack 29 for transmission. The motor 28 drives the gear to rotate forward or reversely, and the gear and the rack 29 mesh back and forth for transmission, thereby driving the cover plate 27 to slide back and forth in the chute 26, thereby adjusting the position of the cover plate 27 at the air inlet 25 of the air filter box, and thus adjusting the opening and closing size of the air inlet 25 of the air filter box. Alternatively, the driving mechanism includes a cylinder, the output end of which is connected to the cover plate, and the cover plate is driven to slide back and forth in the chute by extending or retracting the cylinder, thereby adjusting the position of the cover plate at the air inlet of the air filter box, and thus adjusting the opening and closing size of the air inlet of the air filter box.

[0036] Preferably, the cover plate 27 is provided with a handle 30, which can directly pull the cover plate 27 to the position at the air filter box air inlet 25, and can also lift the cover plate 27 during installation or removal. The chassis air inlet 9 is provided with a shutter to prevent external dust and debris from entering.

[0037] Preferably, there are two atomizing humidifiers 17, the end of the third water outlet pipe 18 is connected to two water distribution pipes 32 via a first three-way joint 31, and the ends of the two water distribution pipes 32 are respectively connected to the two atomizing humidifiers 17, so that the atomization effect is good.

[0038] Preferably, a heat exchanger 33 is further provided between the waste heat oil outlet and the inlet of the air compressor oil return pipe 6, the heat exchange oil inlet of the heat exchanger 33 is connected to the waste heat oil outlet through a heat exchange oil inlet pipe 34, the heat exchange oil outlet of the heat exchanger 33 is connected to the first port of a transition joint 36 through a heat exchange oil outlet pipe 35, the second port of the transition joint 36 is connected to the inlet of the air compressor oil return pipe 6, and the third port of the transition joint 36 is connected to the outlet of the air compressor oil outlet pipe 5 and the waste heat oil inlet through a second three-way joint 37. When the temperature of the cold oil is not low enough after it comes out of the waste heat oil outlet of the waste heat recovery device 10, the heat exchanger 33 can be opened, and the cold oil enters the heat exchanger 33 through the heat exchange oil inlet pipe 34 to cool down, and then enters the oil-free air compressor body 2 through the heat exchange oil outlet pipe 35, the transition joint 36 and the air compressor oil return pipe 6.

[0039] Preferably, an oil tank 39 is provided at the lower side of the gear box 38 of the oil-free air compressor body 2, and an oil supply pipe 40 is provided on the oil tank 39 to supply the oil in the oil tank 39 to the top of the gear box 38. An oil pressure balance pipe 41 is provided above the oil tank 39, and the lower end of the oil pressure balance pipe 41 is connected to the top space of the oil tank 39. An oil mist separator 42 is provided at the upper end of the oil pressure balance pipe 41, and an air intake pipe 43 is provided on the upper side wall of the oil mist separator 42. The end of the air intake pipe 43 is connected to the suction end of a centrifugal fan 44, and a discharge pipe 45 is provided at the discharge end of the centrifugal fan 44. A balanced oil return pipe 46 is provided at the bottom of the oil mist separator 42, and the end of the balanced oil return pipe 46 is connected to the oil tank 39. During operation, the centrifugal fan 44 draws air, and the air in the oil tank 39 enters the oil mist separator 42 through the oil pressure balance pipe 41. Since the air contains oil mist, the air and lubricating oil are separated under the action of the oil-contamination separator 42, and the separated clean air enters the centrifugal fan 44 through the suction pipe 43, and then is discharged through the discharge pipe 45, and the separated lubricating oil returns to the oil tank 39 through the balance oil return pipe 46. Since the centrifugal fan 44 draws air from the oil tank 39, a negative pressure is generated in the oil tank 39. After the lubricating oil is lubricated at each meshing point, it flows from the gear box 38 to the oil tank 39 under the action of negative pressure, avoiding the accumulation of lubricating oil in the gear box 38, effectively reducing the mechanical loss of the unit, improving the operating efficiency, and avoiding the adverse effects caused by the increase of the lubricating oil temperature. Part of the lubricating oil in the oil tank 39 can be sprayed to the gear box 38 through the oil supply pipe 40 to provide lubrication and cooling.

[0040] Preferably, the oil pressure balance pipe 41 is provided with a positive and negative pressure diaphragm box pressure gauge 47 for measuring negative pressure conditions, and the intake pipe 43 is provided with a pressure relief pipe 48, in which a pressure relief valve is provided, and an air filter assembly 49 is provided at the end of the pressure relief pipe 48. When the negative pressure in the oil tank 39 is too large, the air in the chassis 1 can enter the intake pipe 43 through the air filter assembly 49 and the pressure relief valve, so that the negative pressure is stabilized within a certain range.

[0041] Preferably, the air compressor exhaust port is connected to the air compressor exhaust pipe 4 through a venturi tube 50, a first one-way valve 51 is provided in the air compressor exhaust pipe 4, an air release pipe 52 is provided on the air compressor exhaust pipe 4 between the first one-way valve 51 and the venturi tube 50, a second one-way valve 53 and a high-temperature solenoid valve 54 located outside the second one-way valve 53 are provided on the air release pipe 52, a muffler 55 is provided at the end of the air release pipe 52, and a safety valve 56 is provided on the air compressor exhaust pipe 4. When the oil-free air compressor body 2 is shut down, the first one-way valve 51 can prevent the compressed air from flowing back into the oil-free air compressor body 2 through the air compressor exhaust pipe 4, thereby preventing the oil-free air compressor body 2 from reversing. At the same time, the high-temperature solenoid valve 54 is opened, and the compressed air in the oil-free air compressor body 2 is discharged through the air compressor exhaust pipe 4 and the air release pipe 52, and will not flow back into the oil-free air compressor body 2, further preventing the oil-free air compressor body 2 from reversing. If the high-temperature battery valve 54 fails, the second one-way valve 53 can prevent external air from entering the air compressor exhaust pipe 4. The muffler 55 plays a silencing role when discharging compressed air. If the air release pipe 52 is not discharged in time or the compressed air pressure in the air compressor exhaust pipe 4 is too high, it can also be discharged through the safety valve 56, which is safer to use.

They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
