Abstract

This utility model discloses a device for efficient recovery of steam condensate and reuse of waste heat, including a tank. The top of the tank is connected to an exhaust pipe, one side of which is connected to a U-shaped pipe, and one side of which is connected to a connecting pipe. The exhaust pipe facilitates the delivery of steam generated in the tank to the interior of the U-shaped pipe. Subsequently, the connecting pipe delivers the steam to the inner cavity of a heat exchanger. Cold water is delivered to the inner cavity of the heat exchanger through an inlet pipe. The waste heat of the steam heats the water inside the heat exchanger, which is then discharged through an outlet pipe. During heat exchange, the steam condensate generated during heat exchange is collected on the inner wall through a collection pipe and then discharged through a drain pipe at the bottom. This achieves the goal of recovering steam condensate and reusing waste heat, thereby avoiding a significant waste of water resources and minimizing the loss of a large amount of waste heat.

Description

Technical Field

[0001] This utility model belongs to the field of energy and environmental protection technology, and in particular relates to a device for efficient recovery of steam condensate and reuse of waste heat. Background Technology

[0002] Steam condensate is water formed when steam changes from a gaseous to a liquid state after releasing heat. In industrial production, steam is often used for heating and driving mechanical equipment. When steam completes its heat exchange mission, its temperature and pressure decrease, water vapor molecules lose energy, aggregate, and condense into small water droplets. These droplets then gather together to form steam condensate.

[0003] In existing industrial production processes, steam, as a widely used energy carrier, plays a crucial role in many stages. However, after completing its heat transfer task, steam condenses into liquid water, known as steam condensate. Traditionally, large quantities of steam condensate are often directly discharged, which not only results in a significant waste of water resources but also leads to the loss of a substantial amount of waste heat. Utility Model Content

[0004] The purpose of this invention is to provide a device for efficient recovery of steam condensate and reuse of waste heat, which can recover steam condensate and reuse waste heat at the same time, thereby avoiding the great waste of water resources and the loss of a large amount of waste heat, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for efficient recovery of steam condensate and reuse of waste heat includes a tank body. The top of the tank body is connected to an exhaust pipe. A U-shaped pipe is connected to one side of the exhaust pipe. A connecting pipe is connected to one side of the U-shaped pipe. A heat exchanger is fixedly connected to one side of the connecting pipe. A water collecting pipe is fixedly connected to the inner cavity of the heat exchanger. The top of the water collecting pipe passes through the heat exchanger and extends to one side of the heat exchanger. A heat exchange tube is provided in the inner cavity of the heat exchanger. The upper end of the heat exchange tube passes through the top of the heat exchanger and is connected to an outlet pipe. The lower end of the heat exchange tube passes through the heat exchanger and is connected to an inlet pipe. A drain pipe is connected to the bottom of the inner cavity of the heat exchanger. A sewage pipe is connected to the bottom of the heat exchanger. Support plates are uniformly fixed on the surface of the heat exchanger.

[0006] Preferably, the exhaust pipe, U-shaped pipe, and connecting pipe are fixedly connected by flanges.

[0007] Preferably, the heat exchange tube is spirally arranged and sleeved on the outside of the water collection tube.

[0008] Preferably, the surface of the water outlet pipe is provided with a water inlet valve, and the surface of the water inlet pipe is provided with a water outlet valve.

[0009] Preferably, one end of the drain pipe is located at the bottom of the inner cavity of the water collection pipe, and the drain pipe is connected to the water collection pipe.

[0010] Preferably, the bottom of the heat exchanger cavity is provided with a drain port for use with a drain pipe, and a drain valve is provided on the surface of the drain pipe.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model, through the set exhaust pipe, facilitates the transportation of steam generated in the tank to the interior of the U-shaped tube. Subsequently, through the connecting pipe, the steam can be transported to the inner cavity of the heat exchanger. Cold water is transported to the inner cavity of the heat exchange tube through the water inlet pipe. The waste heat of the steam is used to heat the water inside the heat exchange tube, and then it is discharged through the water outlet pipe. At the same time as heat exchange, the steam condensate generated during heat exchange can be adsorbed and collected on the inner wall through the water collection pipe, and then discharged through the drain pipe at the bottom. This achieves the purpose of recovering steam condensate and reusing waste heat, thereby avoiding a great waste of water resources and the loss of a large amount of waste heat.

[0013] 2. This utility model sets the heat exchange tube in a spiral shape and sleeves it on the outside of the water collection pipe. The spiral shape allows for a longer pipe to be arranged in the same space, which increases the contact area between the heat exchange tube and the fluid, improves the heat exchange area, and thus enables more efficient heat transfer.

[0014] 3. This utility model, through the drain port designed to work with the drain pipe and the drain valve on the surface, allows impurities such as rust in the fluid to gradually deposit at the bottom of the heat exchanger during operation. The drain pipe can be opened periodically to discharge these impurities, preventing them from accumulating inside the heat exchanger and affecting the heat exchange effect and fluid flow performance. When there are no impurities or dirt accumulation inside the heat exchanger, the fluid can flow more evenly inside the heat exchanger, achieving better heat exchange and thus improving heat exchange efficiency.

[0023] In the following description, embodiments of the steam condensate high-efficiency recovery and waste heat reuse device of the present invention will be described with reference to the accompanying drawings.

A drain port for use with a drain pipe 11 is provided at the bottom of the inner cavity of the heat exchanger 5, and a drain valve is provided on the surface of the drain pipe 11. Through the drain port for use with the drain pipe 11 and the drain valve on the surface, impurities such as rust in the fluid will gradually deposit on the heat exchanger during operation. At the bottom of heat exchanger 5, drain pipe 11 can be opened periodically to discharge impurities, preventing them from accumulating inside the heat exchanger 5 and affecting heat exchange efficiency and fluid flow performance. When there are no impurities or scale buildup inside heat exchanger 5, the fluid can flow more evenly within the heat exchanger, achieving better heat exchange and thus improving heat exchange efficiency. A water collection pipe 6 is fixedly connected to the inner cavity of heat exchanger 5. The top of the water collection pipe 6 passes through heat exchanger 5 and extends to one side of heat exchanger 5. A heat exchange tube 7 is installed inside the inner cavity of heat exchanger 5. The heat exchange tube 7 is spirally arranged and sleeved on the outside of the water collection pipe 6. By setting the heat exchange tube 7 in a spiral shape... Furthermore, it is sleeved on the outside of the water collection pipe 6. The spiral shape allows for the arrangement of longer pipes within the same space, increasing the contact area between the heat exchange tube 7 and the fluid, thereby improving the heat exchange area and achieving more efficient heat transfer. The upper end of the heat exchange tube 7 passes through the top of the heat exchanger 5 and is connected to the water outlet pipe 8. The lower end of the heat exchange tube 7 passes through the heat exchanger 5 and is connected to the water inlet pipe 9. The bottom of the inner cavity of the heat exchanger 5 is connected to the drain pipe 10, and the bottom of the heat exchanger 5 is connected to the sewage pipe 11. Support plates 12 are evenly fixed on the surface of the heat exchanger 5. The steam generated by the tank 1 is easily transported through the exhaust pipe 2. The steam is then transported to the interior of the U-shaped tube 3 via the connecting pipe 4, and cold water is transported to the interior of the heat exchanger 5 via the inlet pipe 9. The water inside the heat exchanger 7 is heated by the waste heat of the steam and then discharged through the outlet pipe 8. During the heat exchange, the steam condensate generated during the heat exchange is collected on the inner wall by the water collection pipe 6 and then discharged through the drain pipe 10 at the bottom. This achieves the goal of recovering the steam condensate and reusing the waste heat, thereby avoiding a huge waste of water resources and the loss of a large amount of waste heat.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates an embodiment of a high-efficiency steam condensate recovery and waste heat reuse device, comprising a tank 1. A steam exhaust pipe 2 is connected to the top of the tank 1. A U-shaped pipe 3 is connected to one side of the steam exhaust pipe 2, and a connecting pipe 4 is connected to one side of the U-shaped pipe 3. The connections of the steam exhaust pipe 2, U-shaped pipe 3, and connecting pipe 4 are fixedly connected by flanges. The flanges ensure reliable connection and high sealing between the steam exhaust pipe 2, U-shaped pipe 3, and connecting pipe 4, and facilitate installation and disassembly. A heat exchanger 5 is fixedly connected to one side of the connecting pipe 4. A water collection pipe 6 is fixedly connected to the inner cavity of the heat exchanger 5. The top of the water collection pipe 6 penetrates the heat exchanger 5 and extends to one side of the heat exchanger 5. The inner cavity of the heat exchanger 5 is provided with… The heat exchange tube 7 has an upper end that passes through the top of the heat exchanger 5 and is connected to a water outlet pipe 8. A water inlet valve is installed on the surface of the water outlet pipe 8, and a water outlet valve is installed on the surface of the water inlet pipe 9. The water inlet valve can precisely control the flow rate and velocity of the water entering the heat exchanger 5, and adjust the water input according to actual needs to meet different requirements. At the same time, the water outlet valve can control the water outflow, ensuring the stability of the water level and flow state in the equipment, making the equipment operation more reliable. The lower end of the heat exchange tube 7 passes through the heat exchanger 5 and is connected to a water inlet pipe 9. A water pump is installed at one end of both the water outlet pipe 8 and the water inlet pipe 9. A drain pipe 10 is connected to the bottom of the inner cavity of the heat exchanger 5, and a sewage pipe 11 is connected to the bottom of the heat exchanger 5. Support plates 12 are evenly fixed on the surface of the heat exchanger 5.

[0028] Working principle: When using this utility model, the user starts the tank 1 to start the operation. The steam generated by the tank 1 is transported to the inside of the U-shaped tube 3 through the exhaust pipe 2. The steam can be transported to the connecting pipe 4 through the U-shaped tube 3, and then to the inner cavity of the heat exchanger 5 through the connecting pipe 4. Then, the water pump is started and the water inlet valve is opened to transport cold water to the inner cavity of the heat exchange tube 7 through the water inlet pipe 9. Then, the water inside the heat exchange tube 7 is heated by the residual heat of the steam. After heating, the heated water can be discharged through the water outlet pipe 8 by starting the water pump and opening the water outlet valve. At the same time, the steam condensate generated during heat exchange can be adsorbed and collected on the inner wall through the water collection pipe 6. The collected condensate can slide down due to the center of gravity and then be discharged through the drain pipe 10. After a period of use, the drain valve can be opened to discharge the impurities inside the heat exchanger 5 through the drain pipe 11.
