Description

Technical Field

[0001] The utility model belongs to the technical field of heat transmission and supply, and specifically relates to a heat exchange device for a large temperature difference unit. Background Art

[0002] With the rapid development of my country's market economy, the demand for steam by industrial enterprises is also increasing. Due to its high comprehensive energy utilization rate and advantages such as energy saving and environmental protection, the surplus steam from power generation can be effectively utilized. Cogeneration of heat and power for centralized heating has become an important development trend of regional heating in my country. At the same time, the long-distance pipeline transmission capacity has gradually become a problem in the development of centralized heating.

[0003] After searching the document with publication number (CN219607191U), a large temperature difference long-distance heating device that takes into account industrial heat use is disclosed, which relates to the field of heating technology. The utility model includes a large temperature difference heat exchange unit and a temperature-rising absorption heat pump. The heat network supply water enters the large temperature difference heat exchange unit through the temperature-rising absorption heat pump and the hot water pipeline for heat exchange, and then flows back to the temperature-rising absorption heat pump through the hot water pipeline for cooling to generate low-temperature return water from the heat network.

[0004] The above device supplies water through the heating network, passes through the heating absorption heat pump, and is cooled to hot water, which enters the absorption type large temperature difference heat exchange unit. The heat exchange and cooling are low-temperature water, which passes through the heating absorption heat pump again, and is heated to low-temperature return water from the heating network to flow out, so as to produce high-temperature hot water or steam during long-distance hot water transportation. However, the above device cannot automatically adjust the flow rate in the pipeline, and manual labor is required to adjust the valves of the external pipeline. When the liquid flow in the pipeline is small, the flow rate is slow, resulting in heat loss during the transportation of the liquid, resulting in low heat exchange efficiency.

[0005] In view of this, the present utility model is proposed. Utility Model Content
