Description

Technical Field

[0001] The utility model relates to the technical field of steam engines, in particular to a heat pump steam engine. Background Art

[0002] High-temperature heat pumps generally produce hot water with an outlet temperature exceeding 60°C. If the heating temperature exceeds 100°C, steam can theoretically be generated at atmospheric pressure, allowing these heat pumps to be used as steam generators to meet industrial and daily needs. Heat pump steam engines are a new type of compression-type high-temperature heat pump device designed to generate high-temperature steam. Heat pump steam units with medium and low-temperature heat sources can utilize industrial waste heat resources at 40-70°C, as well as lower-grade heat sources such as geothermal energy, to produce high-temperature steam exceeding 100°C.

[0003] The main sources of waste heat from steam condensate in cigarette factories are condensate generated by process steam from silk-making equipment, process steam condensate from combined workshop equipment, and condensate heated by air conditioning steam. This condensate generates large volumes of water at high temperatures, necessitating a heat pump steam generator that can effectively utilize the residual heat from this process condensate to generate high-temperature steam exceeding 100°C for humidification of process air conditioning units at low energy consumption and cost. Furthermore, when condensate flows through the evaporator for extended periods, the calcium and magnesium ions contained in the water easily form scale on the inner walls of the heat exchange tubes, reducing the heat exchange efficiency between the working medium and the waste heat from the condensate.

[0045] When the heat pump steam engine of the present invention is in use, the heat source enters the top of the outer shell 11 through the heat source inlet 12, flows downward to the bottom of the outer shell 11 through the inner tube body 18, and is then discharged through the heat source outlet 13; the low-temperature and low-pressure liquid working medium enters the lower diversion chamber 212 through the refrigerant inlet 15, and then flows along the cavity structure formed between the inner tube body 18 and the outer tube body 19 into the upper diversion chamber 211, and then flows out through the refrigerant outlet 16.

[0046] The utility model improves energy utilization efficiency, reduces greenhouse gas emissions, lowers production and operation costs, and improves the economic benefits of the system by recycling and utilizing low-grade thermal energy; the structural composition of the inner tube body 18 and the outer tube body 19 enables sufficient heat exchange between the working medium and the condensate, and the provision of the ultrasonic cleaning unit 22 can perform convenient and high-frequency cleaning of the inner wall of the inner tube body 18.

[0047] To ensure sufficient heat exchange between the working medium and the condensate, both the inner tube body 18 and the outer tube body 19 are circular tube structures. The inner tube body 18 and the outer tube body 19 are coaxially arranged, and a circular cavity structure is formed between the inner tube body 18 and the outer tube body 19. During the process of flowing in the circular cavity structure, the working medium fully contacts the surface of the inner tube body 18, thereby achieving efficient heat exchange.

[0048] To ensure stable installation of upper inner tube baffles 171, upper outer tube baffles 201, lower outer tube baffles 202, and lower inner tube baffles 172, the inner wall of outer shell 11 is circular. Each of these is a circular plate structure. The edges of upper inner tube baffles 171, upper outer tube baffles 201, lower outer tube baffles 202, and lower inner tube baffles 172 are welded to the inner wall of outer shell 11. The upper inner tube baffles 171, upper outer tube baffles 201, lower outer tube baffles 202, and lower inner tube baffles 172 welded to outer shell 11 are structurally stable and well-sealed, effectively isolating the working medium from condensate and providing stable support for inner tube body 18 and outer tube body 19.

[0049] In order to effectively clean the inner wall of the inner tube 18 through the ultrasonic cleaning unit 22, the ultrasonic cleaning unit 22 is installed on the lower side of the outer shell 11 and is connected to the interior of the outer shell 11. When the ultrasonic cleaning unit 22 is in operation, the ultrasonic waves generated by the ultrasonic cleaning unit 22 cause cavitation, acceleration, and straight flow in the liquid, thereby indirectly cleaning the deposits on the inner wall of the inner tube 18, so that the deposits are quickly removed.

[0050] To ensure the reliable operation of the heat pump compressor 2, the ultrasonic cleaning unit 22 includes an ultrasonic housing 221 and an ultrasonic transducer 222. The ultrasonic housing 221 is mounted on the outer surface of the outer shell 11, and the ultrasonic transducer 222 is mounted inside the ultrasonic housing 221. The mounting surface of the ultrasonic transducer 222 is in contact with the surface of the outer shell 11. The ultrasonic transducer 222 can be protected by the housing and operate reliably.

[0051] To ensure the cleaning effect of the ultrasonic cleaning units 22, there are multiple ultrasonic cleaning units 22, and all ultrasonic cleaning units 22 are evenly arranged around the central axis of the outer shell 11. When multiple ultrasonic cleaning units 22 are working simultaneously, the inner walls of the multiple inner tubes 18 above can be evenly washed by the water flow.

[0052] In the process air-conditioning units using the existing technology, traditional low-grade thermal energy is not effectively recycled and utilized. The condensate generated by the process steam of the silk-making equipment, the condensate of the process steam of the combined workshop equipment, and the condensate heated by the air-conditioning steam are severely scaled when they are recovered. The heat pump steam engine of the present application combines the evaporator 1 with the ultrasonic cleaning unit 22, which not only achieves efficient recycling of the condensate, but also solves the problem of scale formation on the inner wall of the heat exchange tube by the condensate in the prior art. Low-grade thermal energy is the waste heat of the steam condensate in the cigarette factory. This breaks the limitations of the heat pump steam engine in the prior art in terms of thermal efficiency improvement and scale treatment, and provides a new technical path for industrial waste heat utilization and steam production.

[0053] The heat pump steam engine adopts a circular cavity structure formed by nesting the inner tube body 18 and the outer tube body 19, so that the working medium and the condensate can fully contact each other during the flow process, thereby improving the heat exchange efficiency. This is an improvement to the existing heat exchanger.

[0054] The ultrasonic cleaning unit 22 is integrated into the outer shell of the evaporator 1. Through ultrasonic cavitation, acceleration, and direct flow, it achieves high-frequency and convenient cleaning of the inner wall of the inner tube 18, effectively preventing scale formation. This design solves the scaling problem that has long plagued the industrial waste heat utilization field.

[0055] Heat pump steam engines recycle low-grade thermal energy, which serves as waste heat from steam condensate in cigarette factories. This reduces energy consumption and greenhouse gas emissions, aligning with national energy conservation and emission reduction policies. Utilizing waste heat to produce high-temperature steam reduces production and operating costs. Furthermore, the integration of ultrasonic cleaning units 22 reduces the frequency and cost of manual cleaning. The efficient heat exchange structure and the use of ultrasonic cleaning units 22 improve the system's thermal efficiency and operational stability, thereby enhancing the company's economic benefits and market competitiveness.

[0056] With the acceleration of industrialization and urbanization, energy demand continues to increase, while energy shortages and environmental pollution are becoming increasingly severe. Therefore, the development of efficient, energy-saving, and environmentally friendly energy utilization technologies is particularly important. The heat pump steam engine proposed in this embodiment is a solution to the current problems in the field of energy utilization. It not only effectively recycles and utilizes low-grade thermal energy resources, reducing production and operating costs; it also solves the scaling problem through the use of the ultrasonic cleaning unit 22, improving the thermal efficiency and operational stability of the system. Therefore, the research and development and application of this heat pump steam engine are of great practical significance and urgency.

[0057] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
