Description

Technical Field

[0001] This invention relates to the technical field of steam pipeline drainage, specifically to an air-cooled steam pipeline drainage system. Background Technology

[0002] Currently, most steam traps on the market are installed on the ground. During the drainage process, steam is emitted to varying degrees, which cannot completely achieve the effect of "blocking steam and draining water". Therefore, environmental problems such as noise pollution, white steam, and high temperature radiation will occur. Moreover, once a leak occurs, the problem will be aggravated and seriously affect the appearance of the city. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an air-cooled steam pipeline drainage system, which effectively solves the issues of noise emissions, high-temperature radiation, and white vapor diffusion during the drainage process, and plays a significant role in environmental protection and urban beautification.

[0004] An air-cooled steam pipe drainage system, characterized in that it comprises:

[0005] The steam trap is connected to a pipe, which includes a first pipe connected to a steam pipe and a second pipe for draining condensate and a portion of the steam.

[0006] Soft drink pipe;

[0007] Soda water guide pipe;

[0008] Air-cooled bushing;

[0009] And heat dissipation sleeves;

[0010] The output end of the second pipeline is located in the lower cavity of the air-cooled jacket. A steam-water guide pipe is fixedly provided on the upper part of the steam-water connector. The lower sections of the steam-water connector and the steam-water guide pipe are located in the upper cavity of the air-cooled jacket. The upper section of the steam-water guide pipe is inserted into the lower cavity of the heat dissipation jacket. Several openings arranged in the height direction are arranged around the upper end of the steam-water guide pipe. Several layers of fins are arranged on the inner wall of the upper cavity of the heat dissipation jacket. Each layer of fins is staggered to form staggered channels. A discharge hole is provided at the top of the heat dissipation jacket. Several water outlet holes are provided on the bottom plate of the heat dissipation jacket.

[0011] There is a gap between the bottom inlet of the steam-water connector and the outlet of the second pipeline. The air-cooled jacket has several air inlets arranged around the gap in the height direction. The air inlets facilitate the inflow of relatively cooling gas when steam flows into the steam-water connector, thereby cooling and depressurizing the steam.

[0012] Its further features are:

[0013] It also includes a nozzle, the second pipeline is a vertical pipeline, and the output end of the second pipeline is fixedly connected to a nozzle, which is arranged facing upwards;

[0014] The air-cooled jacket is located above the ground. The air-cooled jacket is a hollow tube. The upper section of the second pipeline and the lower section of the steam-water guide pipe are respectively sealed and installed at both ends of the air-cooled jacket. The first pipeline is connected to the steam pipeline drain pipe.

[0015] It also includes a heat dissipation hood, which is installed at the exhaust hole above the heat dissipation sleeve to further reduce noise;

[0016] There is a gap between the bottom inlet of the steam-water connector and the outlet of the nozzle. The air-cooling sleeve has several air inlets arranged around the gap in the height direction. The air inlets facilitate the inflow of relative cooling gas when steam flows into the steam-water connector, ensuring that no pressure difference occurs and performing cooling and depressurization treatment.

[0017] The input end of the soda guide tube is equipped with the soda connector, which is a hollow tube. The inner diameter of the soda connector gradually increases from bottom to top. The small diameter end of the soda connector faces the nozzle, and the large diameter end of the soda connector is connected to and communicates with the input end of the soda guide tube.

[0018] The steam-water guide tube has openings around the output end of the heat dissipation sleeve in the height direction, and the output end of the steam-water guide tube is located inside the heat dissipation sleeve.

[0019] The outer diameter of the steam-water guide pipe is smaller than the outer diameter of the heat dissipation sleeve. The bottom plate of the heat dissipation sleeve is provided with a water outlet hole corresponding to the outer surface area of ​​the steam-water guide pipe. The water outlet hole is used for drainage, and the opening height at the lowest position is higher than the water outlet hole.

[0020] The central axes of the second pipe, nozzle, steam-water connection pipe, steam-water guide pipe, air-cooled jacket, heat dissipation jacket and heat dissipation hood are on the same axis.

[0021] After adopting this invention, the condensate and some steam in the steam pipe enter the first pipe of the steam trap connection pipe, then turn through the second pipe and enter the air-cooled jacket. Under high pressure, it flows sequentially through the steam-water connector and the steam-water guide pipe, and is sprayed into the heat dissipation jacket through the opening at the output end of the steam-water guide pipe. It contacts the fins for heat exchange and condenses into water. Then, the heat in the heat dissipation jacket is discharged through the discharge hole, and the condensate is discharged through the water outlet hole on the bottom plate. By installing an air-cooled jacket on the steam trap pipe, the high-temperature and high-pressure steam exchanges heat with the air, and is then sprayed into the heat dissipation jacket through the steam-water guide pipe for further cooling by the fins before being discharged. This effectively solves the problems of noise emission, high-temperature radiation, and white steam diffusion during the drainage process, and plays an important role in environmental protection and urban beautification.

The steam trap connection and installation pipe 1 includes a first pipe 11 and a second pipe 12. The first pipe 11 is used to connect the condensate and part of the steam in the steam pipe, and the second pipe 12 is a turning pipe and is arranged vertically.

[0030] The air-cooled condensate drain assembly is installed vertically. The air-cooled jacket 5 is a hollow tube. Both ends of the air-cooled jacket 5 are sealed with condensate traps connecting to the pipe 1 and the steam-water guide pipe 4, respectively. The output end of the first pipe 11 and the steam-water guide pipe 4 is located outside the air-cooled jacket 5; the output end of the second pipe 12 and the input end of the steam-water guide pipe 4 are located inside the air-cooled jacket 5 and are positioned opposite each other. The nozzle 2 outlet faces the input end of the steam-water guide pipe 4. An air inlet 51 is provided on the air-cooled jacket 5 to allow air to enter. In practice, a gap is left between the bottom inlet of the steam-water connector 3 and the nozzle 2. Several air inlet holes are arranged around the gap along the height of the air-cooled jacket 5. These air inlet holes are the air inlets 51, facilitating the flow of cooling gas when steam flows into the steam-water connector 3, thus cooling and depressurizing the steam. In practice, the diameter of the four equally spaced air inlet holes is 60mm.

[0031] To buffer the steam and water entering the steam-water guide pipe 4 from nozzle 2, a steam-water connector 3 is installed at the inlet end of the steam-water guide pipe 4. The steam-water connector 3 is a hollow tube with its inner diameter gradually increasing from bottom to top. The smaller diameter end of the steam-water connector 3 faces nozzle 2, and the larger diameter end is connected to the inlet end of the steam-water guide pipe 4. The horizontal distance between nozzle 2 and steam-water connector 4 is 50mm to ensure that the steam and water have appropriate pressure.

[0032] To increase the heat dissipation area and enhance the heat dissipation effect, holes 41 are made around the upper output end of the steam-water guide pipe 4 to connect to the input end of the heat dissipation sleeve 7. The output end of the steam-water guide pipe 4 is located inside the heat dissipation sleeve 7. Fins 6 are installed in the upper cavity of the heat dissipation sleeve 7. The fins 6 are installed above the output end of the steam-water guide pipe 4 and are staggered to facilitate the flow of steam and water.

[0033] The steam trap connecting pipe 1 is welded to the steam pipe water supply pipe. The steam trap connecting installation pipe 1 and the nozzle 2 are connected by welding. The steam-water connection pipe 3 and the steam-water guide pipe 4 are connected by welding.

The steam-water guide pipe 4 is welded to the heat dissipation jacket 7. The fins 6 are welded inside the heat dissipation jacket 7. The heat dissipation jacket 7 is welded to the heat dissipation hood 8.

[0034] The central axes of the steam trap connection installation pipe 1, nozzle 2, steam-water connection pipe 3, steam-water guide pipe 4, air-cooled jacket 5, heat dissipation jacket 7, and heat dissipation hood 8 are on the same axis.

[0035] The outer diameter of the steam-water guide pipe 4 is smaller than the outer diameter of the heat dissipation sleeve 7. The bottom plate 71 of the heat dissipation sleeve 7 is provided with a water outlet 711 corresponding to the outer surface area of ​​the steam-water guide pipe 4. The water outlet 711 is used for drainage, and the opening 41 at the lowest position is higher than the water outlet 711.

[0036] In specific implementation: the diameter of pipe 1 for connecting the steam trap is φ22mm, the diameter of pipe 4 for steam-water guide pipe is φ32mm, the diameter of pipe 5 for air-cooled jacket is φ38mm, the diameter of nozzle is φ10mm, and the material of all pipes is 20# steel or Q235B steel. The material of pipe 3 for steam-water connection is 20# steel or Q235B steel, and the material of heat dissipation jacket and fins is 20# steel or Q235B steel.

[0037] The working process of this invention is as follows:

[0038] After the condensate and some steam in the steam pipe enter the steam trap connecting pipe 1, they are mixed with the air entering the air-cooled jacket 5 through the nozzle 2 and then flow through the steam-water connection pipe 3 and the steam-water guide pipe 4 in sequence. They are then sprayed into the heat dissipation jacket 7 through the opening at the output end of the steam-water guide pipe 4, where they come into contact with the fins for heat exchange and condense into water. The heat dissipation hood 8 carries away the heat inside the heat dissipation jacket 7.

[0039] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
