Description

Technical Field

[0001] This utility model belongs to the field of waste heat recovery technology and relates to a steam waste heat recovery device. Background Technology

[0002] Waste heat recovery refers to the process of capturing and reusing heat energy generated during industrial production, power generation, or other energy consumption. Existing methods for recovering steam waste heat mostly involve passing the liquid to be heated through heat exchange tubes, followed by direct contact of excess steam with the tubes. This heats the liquid within the tubes. However, the condensed liquid formed after the steam contacts the tubes also contains heat, which existing waste heat recovery devices cannot fully utilize, resulting in resource waste. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a steam waste heat recovery device. This device solves the problem that the liquid condensed after steam comes into contact with the heat exchange tube also contains a certain amount of heat, which existing steam waste heat recovery devices cannot fully utilize, resulting in resource waste.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A steam waste heat recovery device is characterized by comprising a base, a heat exchange box fixedly connected to the base, a first heat exchange tube fixedly connected inside the heat exchange box, an air inlet pipe fixedly connected to one side of the lower end of the heat exchange box, an exhaust pipe fixedly connected to one side of the upper end of the heat exchange box, a water outlet pipe fixedly connected to the bottom end of the heat exchange box, and two collection boxes slidably connected to the base below the water outlet pipe, with a second heat exchange tube fixedly connected inside the collection boxes.

[0006] In the aforementioned steam waste heat recovery device, the upper ends of both the first heat exchange tube and the second heat exchange tube are connected to water inlet pipes, and the lower ends of both the first heat exchange tube and the second heat exchange tube are connected to drain pipes. Both the water outlet pipe and the drain pipe are equipped with solenoid valves.

[0007] In the aforementioned steam waste heat recovery device, the heat exchange box has an opening at the top, a sealing block is detachably snapped into the opening, a filter screen is fixedly connected to the lower end of the sealing block, the filter screen is in contact with the exhaust pipe, a cover plate is fixedly connected to the upper end of the sealing block, and a handle is fixedly connected to the upper end of the cover plate.

[0008] In the aforementioned steam waste heat recovery device, the first heat exchange tube is provided with metal fins.

[0009] In the aforementioned steam waste heat recovery device, the heat exchange box is equipped with an insulation layer.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The condensate produced after the steam comes into contact with the first heat exchange tube comes into contact with the liquid in the second heat exchange tube, heating the liquid in the second heat exchange tube. When there is enough condensate in one of the collection boxes, the sliding collection box discharges the condensate into the other collection box for heat exchange, thus making full use of this part of the heat and avoiding waste of resources.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figure 1 As shown,

[0017] A steam waste heat recovery device, characterized in that it includes a base 2, a heat exchange box 3 fixedly connected to the base 2, a first heat exchange tube 4 fixedly connected inside the heat exchange box 3, an air inlet pipe 5 fixedly connected to one side of the lower end of the heat exchange box 3, an exhaust pipe 6 fixedly connected to one side of the upper end of the heat exchange box 3, a water outlet pipe 7 fixedly connected to the bottom end of the heat exchange box 3, and two collection boxes 8 slidably connected to the base 2 below the water outlet pipe 7, with a second heat exchange tube fixedly connected inside the collection box 8.

[0018] In this embodiment, excess steam enters the heat exchange box 3 through the inlet pipe 5 and comes into contact with the first heat exchange tube 4, heating the liquid inside the first heat exchange tube 4. The condensate produced after the steam comes into contact with the first heat exchange tube 4 falls from the outlet pipe 7 into the collection box 8. This condensate with heat comes into contact with the liquid inside the second heat exchange tube, heating the liquid inside the second heat exchange tube. When there is enough condensate in one of the collection boxes 8, the collection box 8 is slid to discharge the condensate into the other collection box 8 for heat exchange, thereby making full use of this part of the heat and avoiding waste of resources.
