It is widely used in the field of energy conservation and emission reduction. At present, in the process production of cigarette factories, steam condensate becomes an available low-grade heat source due to its large water volume and high temperature. However, most traditional humidification equipment relies on boilers to generate high-pressure steam for constant temperature and humidity control of process air-conditioning units, which has the problems of high energy consumption and low operating efficiency.

[0003] To solve the above problems, heat pump steam engines are proposed to convert the waste heat of steam condensate into reusable low-pressure steam, which can not only replace boiler steam for process humidification, but also reduce energy consumption and improve system operation stability. However, in the specific implementation, the steam engine condensing device still faces the following technical difficulties:

[0004] During tobacco drying, steam water will contain a lot of impurities, which are easy to accumulate on the inner wall of the condensation chamber and the liquid-vapor separation component, resulting in insufficient heat exchange between high-temperature steam and low-temperature liquid during the heat exchange process, limiting the energy-saving potential of the heat pump steam engine, reducing heat exchange efficiency, affecting long-term stable operation, and lacking an efficient cleaning and maintenance mechanism. Traditional manual cleaning methods are cumbersome and costly.

[0029] When in use, the tobacco steam water input pipe is connected to the lower side of the water inlet pipe 3, so that the high-temperature steam water passes through the interior of the heat exchange tank 2 and is discharged from the water outlet pipe 5, and the input end of the liquid-steam separation device is connected to one end of the heat exchange tube 6 through a pipe, and the other end of the heat exchange tube 6 is connected to the liquid discharge end of the liquid-steam separation device, so that when the liquid flows through the interior of the heat exchange tube 6, it will be heated by the high-temperature steam water inside the heat exchange tank 2, and then it can generate steam in the liquid-steam separation device;

[0030] The spoiler mechanism 7 includes a connecting component and a spoiler plate 707 on the connecting component. The spoiler plate 707 is located on the upper side of the water inlet pipe 3, and the spoiler plate 707 can be deflected relative to the water inlet pipe 3. The connecting component includes a fixed plate 701. The outer wall of the fixed plate 701 is fixedly connected to the inner wall of the lower opening of the heat exchange tank 2. The left end of the fixed plate 701 is fixedly connected to an extension pipe 702. The lower end of the extension pipe 702 protrudes downward relative to the lower surface of the heat exchange tank 2. A connecting channel 703 running through the left and right is provided inside the fixed plate 701. A convex groove 704 is fixedly connected to the lower right part of the fixed plate 701. The outer wall of one side of the convex groove 704 is fixedly connected to the outer wall of the water inlet pipe 3. A movable groove 708 is provided inside the convex groove 704. The movable groove 708 moves the convex groove 7 04 is connected with the interior of the water inlet pipe 3, the interior of the movable groove 708 is connected with the connecting channel 703 and the interior of the extension pipe 702, the inner wall of the extension pipe 702 is hinged with a rotating cylinder 705 through a torsion spring, the outer wall of the rotating cylinder 705 is fixedly connected with a connecting rod 706, one end of the connecting rod 706 extends to the upper side of the water inlet pipe 3 through the connecting channel 703, and one end of the connecting rod 706 located on the upper side of the water inlet pipe 3 is fixedly connected to the inner wall of the spoiler 707, and a cleaning mechanism 709 is provided on the lower side of the extension pipe 702, the spoiler 707 is inclined, and the upper part of the spoiler 707 is inclined toward the middle part of the upper side of the water inlet pipe 3, the fixed plate 701 is a fan-shaped structure, and the spoiler 707 can move toward the inside of the movable groove 708;

[0031] When tobacco steam water is input into the water inlet pipe 3, the fluid will push the spoiler 707 to deflect toward the inside of the moving groove 708. At this time, the deflection of the spoiler 707 will drive the deflection of the connecting rod 706 and the rotating cylinder 705, thereby tightening the torsion spring at the connection between the insulating block 905 and the insert cylinder 902. After the spoiler 707 is separated from the upper side of the water inlet pipe 3, the elastic force of the torsion spring will drive the spoiler 707 to move toward the upper side of the water inlet pipe 3. Then, under the elastic force of the torsion spring and the pushing action of the fluid, the spoiler 707 will continuously reciprocate, thereby continuously interfering with the motion trajectory of the fluid on the upper side of the water inlet pipe 3, so that the fluid entering the heat exchange tank 2 can merge with the original steam water inside the heat exchange tank 2, thereby better heat exchange and condensation;

[0032] The cleaning mechanism 709 includes a water storage tank 901, the upper side of the water storage tank 901 is fixedly connected to the lower side of the extension tube 702, the inner wall of the water storage tank 901 contacts the lower outer wall of the sealing plate 904, the middle part of the lower surface of the inner wall of the water storage tank 901 is fixedly connected with an insert cylinder 902, the interior of the insert cylinder 902 is plugged with an insert rod 903, the upper end of the insert rod 903 extends to the interior of the rotating drum 705, the upper side of the insert rod 903 is fixedly connected with a sealing plate 904, the outer wall of the sealing plate 904 is threadedly connected to the inner wall of the rotating drum 705, and the sealing plate 904 is fixedly connected to the inner wall of the rotating drum 705. 04 and the plug rod 903 are provided with circular holes that penetrate up and down, and an insulating block 905 is fixedly connected to the lower side of the water storage tank 901, and a conductive rod 906 is arranged on the insulating block 905, and the upper end of the conductive rod 906 extends to the inside of the water storage tank 901, the insert cylinder 902 is a hexagonal prism structure with hollow side walls, and the outer wall of the plug rod 903 is a hexagonal prism structure, the insert cylinder 902 and the plug rod 903 cannot rotate relative to each other, and two conductive rods 906 are arranged on the insulating block 905, and the two conductive rods 906 are respectively an anode and a cathode;

[0033] During the continuous deflection of the drum 705, since its inner wall is threadedly connected to the outer wall of the sealing plate 904, the sealing plate 904 will be reset due to the continuous deflection of the drum 705 and then continuously reciprocate downward and upward, so that when the sealing plate 904 descends, the stored fluid in the water storage tank 901 is discharged upward through the circular hole in the middle of the sealing plate 904. When the sealing plate 904 moves upward, the fluid in the water storage tank 901 is drawn into the circular hole in the middle of the sealing plate 904, thereby generating turbulence in the middle of the heat exchange tank 2, which can better exchange heat between the high-temperature steam water and the water in the heat exchange tube 6, and when the sealing plate 904 descends, the water can be electrolyzed through the conductive rod 906 to generate gas, thereby instantly The internal pressure of the water storage tank 901 is increased, so that the water in the middle of the sealing plate 904 is sprayed farther, and the impact force of the water flow is stronger, which can flush the outer wall of the heat exchange tube 6. Since the pressure on the lower side of the sealing plate 904 increases instantly, the resistance when the drum 705 and the sealing plate 904 are relatively deflected will increase, which will slow down the movement speed of the spoiler 707 when pushed by the fluid, so that the guiding effect on the fluid is enhanced, thereby increasing the mixing degree of the fluid inside the heat exchange tank 2, thereby increasing the heat exchange efficiency, and the movement state of the fluid is constantly changed, which can reduce the adhesion of impurities inside the steam water to the inner wall of the heat exchange tank 2 and the outer wall of the heat exchange tube 6, and can consume less energy to ensure the heat exchange efficiency of the device;

[0034] The cleaning mechanism 709 also includes a threaded barrel 907, one end of which is fixedly connected to the side wall of the water storage tank 901, and the internal thread of the threaded barrel 907 is connected to a threaded tube 908, one end of the threaded tube 908 penetrates the water storage tank 901 and extends to the outside of the water storage tank 901, and the inner wall of the threaded barrel 907 near the insert cylinder 902 is fixedly connected to a spring 909, and the other end of the spring 909 is fixedly connected to a sealing sheet 910, and the outer wall of the sealing sheet 910 contacts the outer wall of the threaded tube 908, and a material groove 911 is provided at one end of the threaded tube 908 located inside the threaded barrel 907, and a discharge port 912 is provided on the threaded barrel 907 at the material groove 911, and the height of the threaded barrel 907 is located in the middle of the insert cylinder 902, and when the material groove 911 is located at the discharge port 912, the spring 909 is in a compressed state, and when the spring 909 is in a relaxed state, the sealing sheet 910 is located on the left side of the discharge port 912;

[0035] When in use, the threaded tube 908 can be taken out of the water storage tank 901 by rotating the threaded tube 908. At this time, the sealing sheet 910 will seal the discharge port 912 due to the thrust of the spring 909. After adding detergent into the material tank 911, the threaded tube 908 is inserted into the threaded tube 907 to connect the material tank 911 with the discharge port 912. Due to the constantly changing water flow inside the water storage tank 901, the detergent inside the material tank 911 will be cleared out and discharged into the heat exchange tank 2. Since the pressure of the water discharged from the upper side of the sealing plate 904 is relatively high, the water flow containing the detergent will quickly diffuse after gushing out of the sealing plate 904, so that the interior of the heat exchange tank 2 can be better cleaned, thereby ensuring the subsequent use efficiency.
