Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery, and in particular to a waste heat recovery device for a heating mixing system. Background Technology

[0002] With the continuous development of the domestic economy and the accelerating pace of urbanization, the urban population is also increasing daily. In modern northern cities, winter heating remains a major concern for residents. Centralized heating, as a convenient, easy-to-manage, and fuel-saving heating system, has gradually become the mainstream in modern northern cities. How to better utilize and recycle the surplus hot water generated after centralized heating ends is a crucial step in practicing a green and ecological society. Existing technology announcement CN215114081U proposes a waste heat recovery device for heating equipment, including a base. An insulation box and a purification mechanism are fixedly connected to the upper end of the base. The insulation box is located to the left of the purification mechanism. A heat-absorbing mechanism is fixedly installed at the lower end of the insulation box. A coil is wound around the outer surface of the heat-absorbing mechanism. One end of the coil penetrates the lower right end of the insulation box and is fixedly connected to the left end of the purification mechanism. The other end of the coil is fixedly connected to a conduit. However, since the heat collection coil is wrapped around the outside of the heat absorption tank, most of the heat in the heat collection coil is lost to the external environment. The water inside the heat absorption tank absorbs less heat, and only the water near the tank wall can absorb heat quickly. The water in the middle of the heat absorption tank is difficult to heat, resulting in a low heat recovery rate and low water heating efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a waste heat recovery device for a heating mixing system that ensures temperature uniformity, improves heat exchange efficiency, reduces heat loss, and improves energy utilization.

[0004] This utility model discloses a waste heat recovery device for a heating mixing system, comprising a heat exchange cylinder, a heat exchange component, an output component, a stirring component, and a heat insulation component. The heat exchange component is installed inside the heat exchange cylinder, the stirring component is installed at the top of the heat exchange cylinder, the output component is installed at both the upper and lower ends of the heat exchange cylinder, and the heat insulation component is located on the outer wall of the heat exchange cylinder. Heating water is input into the heat exchange component to heat the liquid inside the heat exchange cylinder. The stirring component agitates the liquid inside the heat exchange cylinder, causing vertical convection to ensure temperature uniformity and improve heat exchange efficiency. The output component is connected to a pipeline, which can be installed next to a tap water pipe. The output component discharges the heat-exchanged liquid to heat the tap water pipe, preventing freezing inside the tap water pipe in cold winter weather. The output component also ensures that the heat exchange cylinder is kept warm, reducing heat loss and improving energy utilization.

[0005] Preferably, the heat exchange assembly includes an inlet pipe, a distribution plate, multiple heat exchange tubes, a manifold, multiple sets of heat exchange rings, and an outlet pipe. The inlet pipe is installed at the bottom of the heat exchange cylinder and is equipped with a throttling valve.

[0007] Preferably, it also includes multiple sets of stirring blades and spiral conveying blades. The stirring blades are installed on the stirring rod and have multiple round holes. The spiral conveying blades are installed on the lower outer wall of the stirring shaft. When the stirring shaft drives the stirring rod to rotate, the stirring rod drives the stirring blades to rotate, increasing the stirring area and ensuring stirring efficiency. At the same time, the stirring shaft drives the spiral conveying blades to rotate, causing the liquid to generate vertical convection, ensuring temperature uniformity and improving heat exchange efficiency.

[0008] Preferably, the output component includes a connecting pipe, an output end, a thermometer, and a speed control valve. The connecting pipe is installed at the bottom of the heat exchange cylinder, and the output end is installed at the top of the heat exchange cylinder. The thermometer and speed control valve are installed on the output end. The connecting pipe and the output end are connected to a pipeline installed next to a tap water pipe.

At the same time, the thermometer can detect the liquid temperature, and the speed control valve controls the liquid flow rate.

[0009] Preferably, the insulation component includes an insulation sleeve, and a vacuum insulation cavity is formed inside the side wall of the heat exchange cylinder. The insulation sleeve is installed on the outer wall of the heat exchange cylinder.
