Description

Technical Field

[0001] This application relates to the field of waste heat recovery technology, and more specifically, to a circulating water heat recovery system. Background Technology

[0002] A circulating water waste heat recovery system generally refers to a system that collects waste heat from water to reduce heat loss. Waste heat recovery and utilization refers to the recycling and reuse of waste heat generated in industrial processes. The main technologies include heat exchange technology, heat-work conversion technology, and waste heat cooling and heating technology.

[0003] In related technologies, to address the significant heat waste and low efficiency of existing circulating water waste heat recovery systems, patent CN211503761U provides a circulating water waste heat recovery system. This system connects a booster pump to an inlet water pipe, which in turn connects to a steam glass tube. The booster pump then transfers water droplets generated inside the steam glass tube to the outlet water pipe, thus achieving waste heat recovery. The outlet water pipe is threaded, and the anti-slip silicone pad and silicone ring inside the outlet water pipe provide a good seal. Simultaneously, the limiting baffle and limiting holes inside the recovery tank provide good protection and limit the steam glass tube. The heat insulation pad on the inner wall of the recovery tank effectively prevents heat loss from inside the tank and also insulates against external temperatures.

[0004] The total amount of energy lost during the use of circulating water is enormous. If this part of the energy is fully utilized and the heat of the circulating water is further recovered as waste heat, the thermal efficiency of the circulating water can be improved. Moreover, the hot water after heat exchange can be used for washing or other purposes, thereby reducing the efficiency of heat use.

[0005] In view of this, we propose a circulating water heat recovery system. Utility Model Content

[0015] 3. Beneficial effects

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] 1. This application utilizes a combination of a heat-conducting pipe, an mounting plate, fins, and a cold water pipe. The mounting plate is installed in the circulating water tank, and one end of the fins is installed inside the circulating water tank, allowing the fins to contact the hot water inside and conduct the hot water to the other end. The installation between the cold water tank and the mounting plate allows the heat on the fins to be conducted to the cold water pipe, heating the cold water inside. Simultaneously, the heat-conducting pipe heats the water inside, effectively recovering residual heat from the circulating water tank. Water can be discharged through one end of the heat-conducting pipe and the inlet pipe for washing or other purposes.

[0018] 2. This application utilizes a combination of a docking plate, mounting groove, docking rod, limiting plate, and spring. The bearing plate supports the cold water tank, and pulling the docking rod causes the limiting plate to move synchronously, allowing the sliding block to slide along the inner side of the sliding groove. This compresses the spring, and one end of the docking plate is installed in the mounting groove. Releasing the pulling sleeve allows the spring's rebound to align one end of the docking rod with the docking hole on the docking plate, thus installing the mounting plate and the cold water tank.
