Description

Technical Field

[0001] This utility model belongs to the field of waste steam recovery technology, and more specifically, it relates to a mobile waste steam recovery device. Background Technology

[0002] Exhaust steam refers to steam that has already performed work, discharged from equipment such as steam engines and turbines, or a small amount of steam carried in non-condensable gases discharged from thermal containers. In industries such as heat, power, and chemicals, exhaust steam is often discharged regularly or temporarily to remove it from containers and equipment for production needs. During the exhaust steam discharge process, it usually carries heat and steam medium, which leads to the loss of some energy and steam medium, resulting in waste of energy and steam medium.

[0003] Existing waste steam recovery devices typically employ fixed heat exchange equipment, which uses cooling water to condense the steam in the waste steam by utilizing the temperature difference, thus recovering the heat and medium carried in the waste steam. However, such waste steam recovery devices have disadvantages such as large size, heavy weight, and fixed location. They can only recover waste steam from large-capacity, specific locations, and specific equipment exhaust points. They are difficult to recover waste steam from sources along or at the end of steam heat pipelines, or from temporary exhaust steam from heat equipment, which are not fixed in location and have small discharge volumes. Since there are usually many such exhaust points, this leads to a significant waste of energy and steam medium. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mobile waste steam recovery device.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A mobile waste steam recovery device includes a base plate with casters mounted on the lower end of the base plate. A housing and a temporary storage water tank are mounted on the upper end of the base plate. An exhaust screen is mounted on the upper end of the housing. An air-cooled fan and a serpentine pipe are installed inside the housing. A waste steam diversion interface assembly is installed at the upper inlet of the serpentine pipe. The lower outlet of the serpentine pipe is connected to the interior of the temporary storage water tank through a condensate collection pipe and a pipeline pump.

[0007] Preferably, the exhaust steam diversion interface assembly includes a contraction tube for intake exhaust steam, and the end of the contraction tube is provided with a telescopic buckle, which is connected to a pull ring by a steel wire rope.

[0008] Preferably, the steel wire rope is covered with a sleeve.

[0009] Preferably, a gravity-type safety valve is also installed on the serpentine tube.

[0010] Preferably, the upper end of the box is provided with a first manhole for inspecting the inside of the box.

[0011] Preferably, the condensate collection pipe is inclined.

[0012] Preferably, a check valve is provided between the pipeline pump and the temporary water tank.

[0013] Preferably, a level gauge is provided on the side of the temporary storage tank, and a second manhole is provided at the top for inspecting the inside of the temporary storage tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By combining the use of serpentine tubes and air-cooled fans, effective cooling and condensation of exhaust steam are achieved, which not only improves condensation efficiency but also reduces energy consumption.

[0016] 2. The gravity-operated safety valve ensures that it can automatically open when the pressure suddenly increases or exceeds the capacity of the device, releasing excess exhaust steam into the atmosphere, thereby protecting the equipment from damage and ensuring the safety of the operators;

[0017] 3. The device is equipped with casters at the bottom, making it easy to move and deploy it to different work locations as needed, increasing its ease of use and site adaptability;

[0018] 4. The automatic delivery of condensate is achieved by using a pipeline pump in conjunction with a check valve, and the temporary storage tank is equipped with a level gauge to display the liquid level in real time, which facilitates monitoring and management.

[0019] 5. The installation of the first and second manholes facilitates the inspection and maintenance of the interior of the tank and the temporary water tank, simplifying the daily maintenance process.

[0020] 6. By recovering waste steam and converting it into reusable water resources, industrial wastewater discharge is reduced and water costs are saved, reflecting the concept of environmental protection.

[0021] In summary, this utility model uses an air-cooled fan to condense the exhaust steam in the serpentine tube into liquid for recovery, reducing the loss of steam medium and realizing the recovery of exhaust steam with irregular locations and small discharge volumes, such as exhaust steam discharged along or at the end of steam heat pipelines and temporary exhaust steam discharged from heat equipment.

[0024] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Example 1:

[0026] like Figure 1 As shown, a mobile waste steam recovery device includes a base plate 16, with casters 15 installed at the lower end of the base plate 16, and a housing 1 and a temporary water tank 10 installed at the upper end of the base plate 16. An exhaust screen 3 is installed at the upper end of the housing 1, and an air-cooled fan 17 and a serpentine pipe 18 are installed inside the housing 1. A waste steam diversion interface assembly is installed at the upper inlet of the serpentine pipe 18, and the lower outlet of the serpentine pipe 18 is connected to the interior of the temporary water tank 10 through a condensate collection pipe 14 and a pipeline pump 12. The condensate collection pipe 14 is inclined, and a gravity safety valve 19 is also installed on the serpentine pipe 18.

[0027] In this embodiment, exhaust steam enters the serpentine pipe 18 through the exhaust steam diversion interface assembly and flows sequentially inside the serpentine pipe 18. The outside of the serpentine pipe 18 is forced to be cooled by an air-cooled fan 17, which condenses the steam in the exhaust steam into liquid. The liquid flows down to the condensate collection pipe 14 at the bottom of the serpentine pipe 18. A pipeline pump 12 is installed at the lowest point of the condensate collection pipe 14. The pipeline pump 12 can be driven by a battery pack 13. At the same time, a check valve 11 is installed at the outlet of the pipeline pump 12, which can transport the condensate to the temporary storage tank 10 for storage and realize the movement function through the moving wheels 15.

[0028] Example 2:

[0029] A mobile waste steam recovery device differs from Embodiment 1 in that the waste steam inlet assembly includes a contraction pipe 5 for inlet waste steam. The end of the contraction pipe 5 is equipped with a telescopic buckle 4, which is connected to a pull ring 8 via a steel wire rope 6. A sleeve 7 is fitted over the steel wire rope 6. By pulling the pull ring 8, the pull ring 8 tightens the telescopic buckle 4, thus tightening the waste steam outlet pipe and the contraction pipe 5. The telescopic buckle 4 covers the steam discharge port, preventing leakage.

[0030] Furthermore, a first manhole door 2 for inspecting the interior of the tank 1 is provided at the upper end of the tank body 1, and a second manhole door 9 for inspecting the interior of the temporary water tank 10 is provided at the upper end of the temporary water tank 10. The provision of the first manhole door 2 and the second manhole door 9 facilitates the inspection and maintenance of the interior of the tank body 1 and the temporary water tank 10, and simplifies the daily maintenance process.

[0031] Furthermore, a check valve 11 is installed between the pipeline pump 12 and the temporary water tank 10, and the automatic delivery of condensate is achieved by using the pipeline pump 12 in conjunction with the check valve 11.

[0032] Furthermore, a level gauge 20 is provided on the side of the temporary water tank 10, which can be used to display the liquid level.

[0033] The working principle of this utility model is as follows:

[0034] First, insert the exhaust steam pipe into the contraction tube 5. Pull the pull ring 8 and tighten the exhaust steam pipe and contraction tube 5 using the telescopic buckle 4. The tightened end covers the steam discharge port, introducing steam into the serpentine tube 18. The air-cooled fan 17 condenses the exhaust steam in the serpentine tube 18 through forced convection. The heat-exchanged air is discharged through the exhaust screen 3, while the condensate flows by gravity into the condensate collection pipe 14 at the bottom of the serpentine tube 18. Because the condensate collection pipe 14 is sloped, it can flow by gravity to the lower end. The condensate is then transported to the temporary storage tank 10 by the pipeline pump 12 driven by the battery pack 13 for temporary storage. The temporary storage tank 10 is equipped with a level gauge 20 for level display and a second manhole 9 for internal inspection. The gravity safety valve 19 installed at the end of the serpentine pipe 18 can open under its own pressure to release steam into the atmosphere when the exhaust steam pressure suddenly increases or exceeds the capacity of the exhaust steam recovery device, preventing the device from overpressured. Meanwhile, the entire device is mounted on a mobile device consisting of casters 15 and a base plate 16, thus realizing the mobility function of this invention.
