Description

Technical Field

[0001] This utility model relates to the field of steam pipeline drainage equipment, specifically to a steam drainage condensation and whitening device. Background Technology

[0002] In steam systems, condensate and non-condensable gases (such as air) are typically drained quickly using steam traps to prevent the formation of white steam (i.e., condensate vapor). These steam traps are often steam traps, which function to prevent steam from condensing and drain water from steam pipes. This ensures even heating of the steam-heating equipment, fully utilizes the latent heat contained in the steam, and ultimately achieves vapor-liquid separation.

[0003] Although steam traps function to prevent steam from escaping and draining water, when steam is directly discharged into the air from steam pipelines, a significant amount of steam-water mixture is often released, resulting in condensate vapor whitening and water vapor pollution. Therefore, how to solve the problem of condensate vapor whitening caused by steam traps has become an urgent issue for those skilled in the art. Utility Model Content

[0004] This invention provides a steam hydrophobic condensation and de-whitening device, which aims to solve the problem of steam whitening when liquid is discharged from a steam system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steam condensation and whitening device includes a steam condensate pipe, the inlet of which is connected to a steam condensate outlet and the outlet of which is connected to a liquid storage device. The top of the liquid storage device is connected in sequence from bottom to top to a drain pipe, a water collection hopper, and a condensation and whitening device. An automatic overflow drain valve is connected to the side of the liquid storage device and a manual drain valve is connected to the bottom.

[0007] Furthermore, the condensation and whitening device is a closed frame with two layers of water distribution structure inside. The water distribution structure has several water outlets evenly distributed on it. The bottom layer of the water distribution structure has a pebble condensation layer on top, and the top layer of the water distribution structure has a corrugated natural cooling layer on top.

[0008] Furthermore, the pebble condensation layer comprises several pebbles of varying sizes.

[0009] Furthermore, the corrugated natural cooling layer comprises several vertically arranged corrugated plates with a spacing of 5-10 mm between adjacent corrugated plates.

[0010] Furthermore, the steam trap is U-shaped, and the outlet of the steam trap extends from the bottom of the liquid storage device through the inner cavity.

[0011] Furthermore, the height of the steam trap extending into the inner cavity of the liquid storage device is one-third of the total height of the liquid storage device, and the outlet end of the steam trap is connected to an umbrella-shaped drainage section.

[0012] Furthermore, the installation height of the manual steam trap is consistent with the height of the steam trap that extends into the inner cavity of the liquid storage device.

[0013] Furthermore, the water collection hopper is funnel-shaped with obliquely cut side walls and a circular bottom.

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

[0015] This invention provides a steam trap condensation and whitening device that combines a steam trap pipe, a liquid storage device, a condensation and whitening device, and an automatic overflow steam trap. The liquid storage device can pre-store the mixture of steam and water and perform preliminary separation to prevent excessive steam from entering the vent pipe. The steam reaches the condensation and whitening device after passing through the vent pipe, and is then condensed and discharged after passing through the pebble condensation layer and the corrugated natural cooling layer. The condensate is evenly distributed and falls through the water distribution structure, where it exchanges heat with the vented steam again, and is finally collected by the water collection hopper and enters the liquid storage device. The water after heat exchange is then discharged through the automatic overflow steam trap. The purpose of steam trap condensation and whitening is achieved through natural cooling and heat exchange. This invention solves the problem of excessive steam-water mixture discharge and whitening pollution caused by traditional steam traps, and also has the advantages of simple and compact structure and easy installation.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this invention should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0021] This utility model discloses a steam condensation and whitening device, including a U-shaped steam condensate pipe 2. The inlet of the steam condensate pipe 2 is connected to a steam condensate outlet 1, and the outlet is connected to a liquid storage device 6 for temporary liquid storage. The top of the liquid storage device 6 is connected sequentially from bottom to top to a drain pipe 7, a water collection hopper 8, and a condensation and whitening device 9. The water collection hopper 8 is a funnel-shaped structure with obliquely cut side walls and a circular bottom. The condensation and whitening device 9 is a closed frame with two layers of water distribution structures 12 inside. Each water distribution structure 12 has several evenly distributed water outlets. The lower water distribution structure 12 has a pebble condensation layer 10 on top, and the upper water distribution structure 12 has a corrugated natural cooling layer 11 on top, used to enhance the steam condensation and whitening effect. The water distribution structure 12 not only provides support for the pebble condensation layer 10 and the corrugated natural cooling layer 11, but also guides the condensed water to fall evenly, reliably exchanging heat with the steam coming from below, reducing the amount of steam. The pebble cooling layer 10 includes multiple pebbles of different sizes, and the corrugated natural cooling layer 11 includes multiple vertically arranged corrugated plates with a spacing of 10mm between adjacent corrugated plates. The corrugated plates are in good contact with the ambient air around them to ensure the cooling effect.

[0022] The steam trap 2 extends from the bottom of the liquid storage device 6 through its inner cavity. The height of the steam trap 2 extending into the inner cavity of the liquid storage device 6 is one-third of the total height of the liquid storage device 6. The outlet end of the steam trap 2 is connected to an umbrella-shaped drainage section 3. When the steam-water mixture is discharged through the umbrella-shaped drainage section 3, it can effectively reduce the impact, intercept most of the steam-water mixture, and exchange heat with the condensate at the bottom, reliably separating steam and water and reducing steam discharge. The side of the liquid storage device 6 is connected to an automatic overflow drain valve 5, and the bottom is connected to a manual drain valve 4. The manual drain valve 4 is used for manual drainage or equipment evacuation when the condensate volume is large. The installation height of the manual drain valve 4 is the same as the height of the steam trap 2 extending into the inner cavity of the liquid storage device 6, which is used to ensure that a certain amount of condensate always accumulates at the bottom of the liquid storage device 6 for heat exchange. When the liquid level is high, it is automatically discharged to avoid poor steam drainage.

[0023] In use, the steam-water mixture flowing in the steam trap 2 first enters the liquid storage device 6 for preliminary steam-liquid separation. The separated liquid volume is stored at the bottom of the liquid storage device 6 for heat exchange. When a certain amount of liquid has accumulated after preliminary steam-liquid separation, it is discharged by the automatic overflow steam trap 5. The steam is discharged upward through the vent pipe 7. The steam passes through the pebble condensation layer 10 and the corrugated natural cooling layer 11 in the condensation and whitening device 9 before being condensed and discharged after whitening. The condensate falls evenly through the water distribution structure 12 and exchanges heat with the discharged steam again. Finally, it is collected by the water collection hopper 8 and enters the liquid storage device 6, realizing steam condensation and whitening. It should be noted that the liquid entering the liquid storage device 6 mentioned in this utility model refers to the water generated in the steam conveying pipeline.
