Abstract
Description
Technical Field
[0001] This utility model belongs to the field of petrochemical storage and transportation technology, specifically relating to a fire-fighting cooling water diversion device for storage tanks with wind-resistant rings. Background Technology
[0002] Petrochemical storage tanks are typically equipped with fixed fire-fighting cooling water systems for cooling the facilities. However, the wind-resistant rings on the tanks can obstruct the flow of fire-fighting cooling water down the tank wall, affecting the effectiveness of fire-fighting cooling and posing a safety hazard. A common design approach is to install a set of spray rings under each wind-resistant ring, but this results in a large number of spray rings and a high water consumption.
[0003] Currently, in cases where cooling water spray rings are not installed at the wind-resistant ring, a flow guiding device is added to the wind-resistant ring to ensure that the fire-fighting cooling water can cover the entire tank wall. However, there are no standardized or regulated practices for the flow guiding device, and there is an urgent need for a fire-fighting cooling water flow guiding device with good cooling effect and stability. Utility Model Content
[0004] The purpose of this invention is to provide a fire-fighting cooling water diversion device that can ensure that fire-fighting cooling water covers the entire tank pipe wall.
[0005] To address the aforementioned problems, this utility model provides a fire-fighting cooling water diversion device for a storage tank with a wind-resistant ring. The device includes a wind-resistant ring connected to the tank wall panel, a guide plate disposed outside the wind-resistant ring, and multiple fasteners connecting the wind-resistant ring and the guide plate. The multiple fasteners are evenly distributed around the tank wall panel. The guide plate is inclined downwards towards one side of the tank wall panel, with its top end extending above the top end of the wind-resistant ring. A predetermined distance is provided between the bottom end of the guide plate and the tank wall panel.
[0006] This utility model discloses a fire-fighting cooling water diversion device for storage tanks with wind-resistant rings. A guide plate is added to the outside of the wind-resistant ring, and the guide plate is securely connected to the wind-resistant ring by fasteners. The guide plate is inclined downwards towards the tank wall. The fire-fighting cooling water flows down along the annular guide groove formed between the wind-resistant ring and the guide plate. The water flow is dispersed by the evenly distributed fasteners. Due to the inclined arrangement of the guide plate, the flowing cooling water will flow at a certain angle towards the guide plate below the wind-resistant ring. Furthermore, a predetermined distance is provided between the bottom of the guide plate and the tank wall. After the water flow forms a vortex in the space below the wind-resistant ring and the guide plate, it flows down evenly from the bottom of the guide plate towards the tank wall, covering the entire tank wall. This provides the beneficial effect of ensuring the fire-fighting cooling water covers the entire tank wall, guaranteeing the cooling effect of the fire-fighting water. Simultaneously, the top of the guide plate is higher than the top of the wind-resistant ring, preventing the fire-fighting cooling water flowing from the wind-resistant ring to the top of the guide plate from splashing.
[0007] In some embodiments, the fixing components are made of steel bars, with multiple sets of steel bars connecting the guide plate and the wind-resistant ring vertically. All steel bars in each adjacent set are staggered horizontally. Therefore, by arranging the fixing components in a layered and staggered manner, the connection stability between the guide plate and the wind-resistant ring can be improved. Furthermore, the multiple layers and staggered arrangement of the steel bars can evenly disperse the flowing cooling water, thereby improving the cooling effect of the fire-fighting cooling water on the tank wall.
[0008] In some implementations, the steel strip between the top of the wind-resistant ring and the deflector is made of round steel. This improves the stability of the connection between the deflector and the wind-resistant ring.
[0009] In some implementations, the deflector plate has a cross-section that is a straight plate inclined towards one side of the tank wall. This facilitates the rapid flow of fire-fighting cooling water, improving the cooling effect.
[0010] In some embodiments, the distance between the bottom end of the baffle plate and the tank wall is 30mm-40mm. This appropriate spacing ensures that the water flow evenly covers the entire tank wall from the bottom end of the baffle plate, providing the beneficial effect of ensuring the fire-fighting cooling water covers the entire tank wall and guarantees the cooling effect of the fire-fighting water.
[0011] In some implementations, the height difference between the top of the deflector and the top of the wind-resistant ring ranges from 40mm to 60mm. This reasonable height difference ensures that the fire-fighting cooling water flowing from the wind-resistant ring to the top of the deflector does not splash.
[0012] In some implementations, the deflector is made of stainless steel.
[0013] In some implementations, round steel bars are welded between the top of the wind-resistant ring and the deflector. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.
[0019] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.
[0020] Figure 1 The diagram schematically illustrates a fire-fighting cooling water diversion device for a storage tank with a wind-resistant ring, according to one embodiment of the present invention. Figure 1 As shown, the device includes a wind-resistant ring 20 connected to the tank wall panel 10, a guide plate 30 disposed outside the wind-resistant ring 20, and multiple fasteners connecting the wind-resistant ring 20 and the guide plate 30. The multiple fasteners are evenly distributed around the tank wall panel 10. The guide plate 30 is inclined downwards towards one side of the tank wall panel 10, and the top of the guide plate 30 is higher than the top of the wind-resistant ring 20. A predetermined distance is provided between the bottom of the guide plate 30 and the tank wall panel 10. In this embodiment, the fasteners are steel bars, and round steel bars 40 can be further selected. The round steel bars 40 are connected between the top of the wind-resistant ring 20 and the top of the guide plate 30 by welding.
[0021] Based on the above structure, the flow guiding device of this utility model adds a flow guiding plate 30 to the outside of the wind-resistant ring 20. The flow guiding plate 30 is firmly connected to the wind-resistant ring 20 by fasteners, and the flow guiding plate 30 is inclined from top to bottom toward the side of the tank wall panel 10. The fire-fighting cooling water flows down along the annular flow guiding groove formed between the wind-resistant ring 20 and the flow guiding plate 30. The water flow is dispersed by the evenly distributed fasteners. Because the flow guiding plate 30 is inclined, the flowing cooling water will flow at a certain angle toward the flow guiding below the wind-resistant ring 20. The guide plate 30 has a predetermined distance between its bottom end and the tank wall plate 10. After the water flow forms a vortex in the space below the wind-resistant ring 20 and the guide plate 30, it flows down from the bottom end of the guide plate 30 towards the tank wall plate 10, evenly covering the entire tank wall. This has the beneficial effect of ensuring that the fire-fighting cooling water can cover the entire tank wall and guarantee the cooling effect of the fire-fighting water. At the same time, the top end of the guide plate 30 is higher than the top end of the wind-resistant ring 20, which can prevent the fire-fighting cooling water flowing from the wind-resistant ring 20 to the top of the guide plate 30 from splashing.
[0022] In a preferred embodiment, combined with Figure 1 and Figure 2 As shown, multiple sets of round steel bars 40 are connected vertically between the guide plate 30 and the wind-resistant ring 20, with all round steel bars 40 in each adjacent set staggered horizontally. Therefore, by arranging the round steel bars 40 in a layered and staggered manner, the connection stability between the guide plate 30 and the wind-resistant ring 20 can be improved. Furthermore, the multi-layered and staggered arrangement of the round steel bars 40 can evenly disperse the flowing cooling water, thereby improving the cooling effect of the fire-fighting cooling water on the tank wall. Figure 2 As shown in the figure, in this embodiment, two layers of round steel 40 are designed as fasteners.
[0023] like Figure 1 As shown, in this embodiment, the cross-section of the guide plate 30 is a straight plate inclined towards one side of the tank wall panel 10. This facilitates the rapid flow of fire-fighting cooling water, improving the cooling effect. In a specific embodiment, the guide plate 30 is made of stainless steel.
[0024] In a preferred embodiment, see Figure 1 As shown, the distance D between the bottom end of the guide plate 30 and the tank wall plate 10 ranges from 30mm to 40mm, and the distance D is preferably 35mm. Therefore, by using a suitable distance, it can be ensured that the water flow from the bottom end of the guide plate 30 towards the tank wall plate 10, evenly covering the entire tank wall and flowing down. This has the beneficial effect of ensuring that the fire-fighting cooling water covers the entire tank wall, guaranteeing the cooling effect of the fire-fighting water.
[0025] Furthermore, the height difference H between the top of the deflector plate 30 and the top of the wind-resistant ring 20 ranges from 40mm to 60mm, and is preferably 50mm. Thus, by ensuring the deflector plate 30 is positioned at a reasonable height, splashing of the fire-fighting cooling water flowing from the wind-resistant ring 20 to the top of the deflector plate 30 is prevented.
[0026] This utility model discloses a fire-fighting cooling water diversion device for storage tanks with wind-resistant rings. An inclined guide plate 30 is added to the outside of the wind-resistant ring 20, with evenly distributed fixing components. This allows water to flow evenly from the bottom of the guide plate 30 towards the tank wall 10, covering the entire tank wall. This ensures the fire-fighting cooling water covers the entire tank wall, guaranteeing effective cooling. Simultaneously, the top of the guide plate 30 extends above the top of the wind-resistant ring 20, preventing splashing of the fire-fighting cooling water flowing from the wind-resistant ring 20 to the top of the guide plate 30.
[0027] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this utility model.
