Description
Technical Field
[0001] This utility model relates to the field of heat recovery technology, specifically to a high-temperature steam collection and recycling device. Background Technology
[0002] The medical process generates a large amount of medical waste. The medical waste needs to be sterilized by high-temperature steam. The exhaust gas used in the high-temperature steam sterilization contains a lot of residual heat, and direct discharge will result in waste.
[0003] A search revealed a patent published on March 11, 2025, in China, with publication number CN222598575U, describing a high-temperature steam recycling device that is easy to maintain. The device generally includes a cover plate and a heat exchange tank. The cover plate has gourd-shaped insertion holes around its perimeter. A rod is installed around the top of the heat exchange tank, with a limit plate at the top of the rod. Screw holes are located on the upper side of the cover plate and the upper side of the heat exchange tank, with a fixing bolt rotatably installed inside each screw hole. A circulation pipe is installed at the bottom of the cover plate, with an inlet pipe and an outlet pipe installed in the inlet and outlet sections of the circulation pipe, respectively.
[0004] Although the existing technical solution described above only requires the removal of a few fixing bolts to remove the cover plate and circulation pipe, which is very convenient and quick, the water after the steam condenses in the device tends to accumulate in the circulation pipe, making it difficult for steam to pass through and reducing the stability of the equipment. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature steam collection and recycling device to solve the problem mentioned in the background technology that water after steam condensation tends to accumulate in the circulation pipe, making it difficult for steam to pass through and reducing the stability of the equipment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature steam collection and recycling device, comprising a heat exchange tank and a top cover. Four evenly distributed support legs are fixedly connected to the bottom of the heat exchange tank, and a base plate is fixedly connected to the bottom of the four support legs. The heat exchange tank is provided with an inlet pipe and an outlet pipe, and a first valve is provided on the outlet pipe. A through hole is opened at the bottom of the heat exchange tank, and a threaded opening is opened at the top of the heat exchange tank. A threaded ring that mates with the threaded opening is fixedly connected to the bottom of the top cover. An air inlet pipe is fixedly connected to the top cover, and an air inlet pipe is installed at the bottom of the air inlet pipe. The device is equipped with a first water distributor, at the bottom of which are provided multiple evenly distributed heat dissipation pipes. The bottom ends of the heat dissipation pipes are connected to a second water distributor, at the bottom of which is provided a vent pipe with a through hole. A sealing plate that matches the through hole is fixedly connected to the outer wall of the vent pipe. A threaded sleeve is provided on the outer wall of the vent pipe. A threaded cylinder that matches the threaded sleeve is rotatably connected inside the through hole. A control handle is provided at the bottom end of the threaded cylinder. A collection box is connected to the bottom end of the vent pipe. The collection box is provided with an exhaust pipe and a drain pipe. A second valve is provided on the drain pipe.

[0007] By adopting the above technical solution, water is injected into the heat exchange tank through the inlet pipe, and the steam pipe is connected to the air inlet pipe, thereby injecting high-temperature steam into the equipment through the air inlet pipe. The high-temperature steam then passes through the first water distributor, the heat dissipation pipe, the second water distributor, and the air outlet pipe in sequence. When the high-temperature steam passes through the heat dissipation pipe, a large amount of heat is transferred from the high-temperature steam to the water, reducing the resources used to heat the water and thus completing the heat exchange and reuse of the high-temperature steam. At this time, the condenser is used to condense the steam in the air outlet pipe, and the condensate flows into the collection tank to complete the collection of condensate. Excess gas is discharged through the exhaust pipe, and the drain pipe cooperates with the second valve to facilitate the discharge of condensate in the collection tank, thereby preventing the condensate from accumulating inside the equipment and improving the stability of the equipment.
[0008] Optionally, the bottom end of the top cover is provided with a first sealing gasket, the bottom end of the first sealing gasket being in close contact with the top end of the heat exchange tank, and the bottom end of the sealing plate is provided with a second sealing gasket, the bottom end of the second sealing gasket being in close contact with the inner lower side wall of the heat exchange tank.
[0009] By adopting the above technical solution, both the first and second sealing gaskets are used to improve the sealing performance of the heat exchange tank and reduce the leakage of hot air and water, thereby improving the stability of the equipment.
[0010] Optionally, a thermometer is installed on the heat exchange tank, with the thermometer probe extending into the interior of the heat exchange tank.
[0011] By adopting the above technical solution, the thermometer is used to detect the temperature in the heat exchange tank, so that personnel can drain the water when it reaches a suitable temperature, thereby improving the heat exchange efficiency.
[0012] Optionally, the collection box is provided with a transparent observation window.
[0013] By adopting the above technical solution, the transparent observation window is used to facilitate personnel to observe the water level in the collection box, thereby facilitating timely drainage and preventing the water in the collection box from overflowing.
[0014] Optionally, a heat-insulating protective shell is fixedly connected to the outer wall of the heat exchange tank.
[0015] By adopting the above technical solution, the heat insulation shell is used to protect the heat exchange tank and prevent heat from escaping.
[0016] In summary, this utility model has at least one of the following beneficial technical effects:
[0017] This high-temperature steam collection and recycling device injects water into the heat exchange tank through the inlet pipe and connects the steam pipe to the inlet pipe, thus injecting high-temperature steam into the equipment. The high-temperature steam then passes sequentially through the first water distributor, the heat dissipation pipe, the second water distributor, and the outlet pipe. When the high-temperature steam passes through the heat dissipation pipe, a large amount of heat is transferred from the high-temperature steam to the water, reducing the resources needed to heat the water and thus completing the heat exchange and reuse of the high-temperature steam. At this time, the condenser is used to condense the steam in the outlet pipe, and the condensate flows into the collection tank to complete the collection of condensate. Excess gas is discharged through the exhaust pipe, and the drain pipe cooperates with the second valve to facilitate the discharge of condensate in the collection tank, thereby preventing the accumulation of steam condensate inside the equipment and improving the stability of the equipment.

A condenser 21 is installed on the water outlet pipe 6. Water is injected into the heat exchange tank 1 through the water inlet pipe 5. A steam pipe is connected to the air inlet pipe 9, thus injecting high-temperature steam into the equipment. The high-temperature steam then passes sequentially through the first water distributor 10, the heat dissipation pipe 11, the second water distributor 12, and the air outlet pipe 13. When the high-temperature steam passes through the heat dissipation pipe 11, a large amount of heat is dissipated through the heat dissipation pipe. Heat pipe 11 transfers heat to the water, reducing the resources needed to heat the water, thus completing heat exchange and reusing the high-temperature steam. At this time, condenser 21 is used to condense the steam in the outlet pipe 13, and the condensate flows into the collection box 17 to complete the collection of condensate. Excess gas is discharged through exhaust pipe 18. Drain pipe 19 cooperates with the second valve 20 to facilitate the discharge of condensate in collection box 17, thereby preventing the condensate from accumulating inside the equipment and improving the stability of the equipment.

[0029] In summary, the working principle and process of this high-temperature steam collection and recycling device are as follows: First, water is injected into the heat exchange tank 1 through the inlet pipe 5. The steam pipe is then connected to the inlet pipe 9, allowing high-temperature steam to be injected into the device. The high-temperature steam then passes sequentially through the first water distributor 10, the heat dissipation pipe 11, the second water distributor 12, and the outlet pipe 13. As the high-temperature steam passes through the heat dissipation pipe 11, a large amount of heat is transferred from the steam to the water, reducing the resources needed to heat the water and thus completing the heat exchange and reuse of the high-temperature steam. At this time, the condenser 21 condenses the steam in the outlet pipe 13, and the condensate flows into the collection tank 17, thus completing the collection of condensate. Excess gas is discharged through the exhaust pipe 1. 8. Drain pipe 19, in conjunction with second valve 20, facilitates the discharge of condensate from collection tank 17, thereby preventing steam condensate from accumulating inside the equipment and improving equipment stability. First sealing gasket 22 and second sealing gasket 23 are used to improve the sealing of heat exchange tank 1, reducing the leakage of hot air and water, thus improving equipment stability. Thermometer 24 is used to detect the temperature in heat exchange tank 1, allowing personnel to drain the water when it reaches a suitable temperature, thereby improving heat exchange efficiency. Transparent observation window 25 allows personnel to easily observe the water level in collection tank 17, facilitating timely drainage and preventing overflow. Insulation protective shell 26 protects heat exchange tank 1, preventing heat leakage.
