Description

Technical Field

[0001] This application belongs to the technical field of thermal power cycles, and specifically relates to a thermal power cycle device for a heat station. Background Art

[0002] A heat station, also known as a heat exchange station or a thermal exchange station, is an important link in a central heating system. Its main function is to pressurize and heat exchange the high-temperature steam or hot water transported from the heat pipeline network, convert it into a secondary heat medium suitable for user use, and transport it to the user end. A thermal power cycle device is a general term for equipment and systems used to convert, store, transmit, and utilize thermal energy, aiming to efficiently utilize thermal energy, reduce energy waste, and reduce environmental impact, convert it into useful thermal energy for heating, refrigeration, or other industrial uses. Through different designs and applications, these thermal power cycle devices improve energy utilization efficiency and are an important part of modern energy utilization and sustainable development. They ensure the stable operation of the thermal system by optimizing the transmission and utilization of thermal energy, and also contribute to environmental protection.

[0003] For example, a utility model patent with the publication number CN217978976U discloses a thermal power cycle device for a heat station. A drainage component is connected to the conical bottom position of the heating tank. A stirring and scraping component is embedded and connected at the middle position above the heating tank, and heat exchange components are symmetrically embedded and connected at both sides above the heating tank. Through the circulating heat exchange between the heat exchange tubes and cold water in the heat exchange component and the auxiliary heating of the heating tubes, and driven by the circulating stirring of the stirring paddles in the stirring and scraping component, on the one hand, it can improve the circulating heat exchange efficiency between the mechanical waste heat of the thermal power device and cold water, and on the other hand, it can improve the uniformity of water-gas heat exchange. After heat exchange, through the circulating scraping of the inner wall of the heating tank by the scraping knife holder in the stirring and scraping component, the alkali scale generated by heat exchange can be circulated and scraped off, and then under the filtration of the filtration mechanism in the drainage component, clean hot water can be discharged.

[0004] However, it is found in actual use that: the heating tank of this device is not thermally insulated. When the flowing hot gas exchanges heat with the water inside the heating tank, the generated hot water flows under the rotation of the stirring component. During this process, due to the non-thermal insulation design of the tank body, the heat dissipated by the hot water will be lost to the environment through the surface of the tank body, resulting in partial heat loss. This heat loss will affect the heat exchange effect inside the heating tank because the loss of heat may reduce the heat exchange efficiency. Therefore, a thermal power cycle device for a heat station is provided. Summary of the Utility Model
