Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler equipment technology, and in particular to a novel windproof structure for steel chimneys. Background Technology
[0002] Steel chimneys are common industrial and civil building facilities, mainly used as structures for emitting waste gas, steam and harmful gases. They are widely used in the flue gas emission of equipment such as boilers and heat treatment furnaces. In order to prevent backflow of flue gas caused by wind, wind shields are installed at the top of steel chimneys.
[0003] Currently, the wind shields installed on top of steel chimneys usually rely on a bucket-shaped cover for shielding. During use, smoke is discharged through Bernoulli's principle. However, most of the openings on these wind shields are directly exposed, and rainwater can easily enter the steel chimney during rainy weather. This can have an adverse effect on the internal temperature of the boiler and can also easily cause corrosion to the inner wall of the steel chimney. Summary of the Invention
[0004] This utility model provides a novel windproof structure for steel chimneys, which can prevent rainwater from entering the steel chimney during rainy weather, thus avoiding adverse effects on the internal temperature of the boiler. It can also prevent corrosion of the inner wall of the steel chimney and extend its service life.

[0008] In at least some embodiments, ten elongated openings are arranged in a ring on the outer wall of the windproof cover body, with ten outer shields and ten inner shields located on the outer and inner sides of these ten elongated openings, respectively.
[0009] In at least some embodiments, the outer baffle is located between the upper and lower drainage hoods, and two inclined plates are symmetrically arranged on the outer side of the outer baffle.
[0010] In at least some embodiments, the main body of both the outer and inner shields is an L-shaped plate, and the width of both the outer and inner shields is twice the width of the elongated opening on the outer wall of the windshield body.
[0011] In at least some embodiments, the bottom of the inner baffle is connected to the top of the water collection tank, and three vertical protrusions are equidistantly arranged on the side of the inner baffle facing the elongated opening on the outer wall of the windproof cover body.
[0012] In at least some embodiments, the water collection trough is an annular trough, and the outer wall of the windproof cover body is also provided with ten semi-circular holes that penetrate from the inside out, and the bottom surface of the semi-circular holes is on the same plane as the bottom inner surface of the water collection trough.
[0013] This utility model provides a novel windproof structure for steel chimneys, which has the following beneficial effects:
[0014] The outer and inner baffles in this invention can block rainwater during rainy weather. The vertical protrusions on the inner baffle, in conjunction with the water collection trough, can also collect rainwater that splashes into the interior. Then, the rainwater will flow out through the semi-circular holes on the main body of the windproof cover.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] This utility model proposes a novel windproof structure for steel chimneys, comprising: a windproof cover body 1;
[0029] An upper hood 2 is welded to the top of the outer side of the main body 1 of the wind shield. During installation, the main body 1 can be fixed to the top of the steel chimney. In use, the main body 1 can expel the flue gas from the steel chimney and also provides wind protection. The bowl-shaped upper hood 2, in conjunction with the lower hood 3, allows more air to flow from the outside of the outer baffle 4, thereby increasing the air velocity at the outer wall of the main body 1 and reducing air pressure. This achieves smoke extraction through Bernoulli's principle. The outer side of the main body 1 is also welded... The system is connected to a lower draft hood 3. The bowl-shaped lower draft hood 3, in conjunction with the upper draft hood 2, allows more air to flow from the outside of the outer baffle 4, thereby increasing the air velocity at the outer wall of the windproof hood body 1 to reduce air pressure, and thus achieving smoke exhaust through Bernoulli's principle. Ten outer baffles 4 are welded in a ring arrangement on the outer wall of the windproof hood body 1. The outer baffles 4 can block rainwater from entering the steel chimney through the long strip opening on the outer wall of the windproof hood body 1 during rainy weather. Furthermore, the symmetrically arranged inclined plates on the outer side of the outer baffle 4 can also guide the airflow, thereby increasing the air velocity at the outer side of the elongated opening on the outer wall of the windproof cover body 1 to reduce the air pressure, and then the smoke in the windproof cover body 1 can be drawn out. Ten inner baffles 5 are also welded in a ring arrangement on the inner wall of the windproof cover body 1. If splashing rainwater enters the elongated opening on the outer wall of the windproof cover body 1, the inner baffles 5 will also block this rainwater, and then this rainwater will flow down the inner baffles 5. The vertical protrusions flow downwards into the water collection trough 6; a water collection trough 6 is also welded to the inner wall of the windproof cover body 1. If splashing rainwater enters the long strip opening on the outer wall of the windproof cover body 1, the inner baffle 5 will also block the rainwater. Then the rainwater will flow downwards along the vertical protrusions on the inner baffle 5 into the water collection trough 6. The water in the water collection trough 6 can flow out through the semi-circular hole on the outer wall of the windproof cover body 1, preventing rainwater from flowing downwards into the steel chimney and causing adverse effects on the boiler.
[0030] In this embodiment of the disclosure, such as Figures 1-4 As shown, both the upper hood 2 and the lower hood 3 are bowl-shaped structures, and the upper hood 2 and the lower hood 3 are symmetrically arranged. The bowl-shaped upper hood 2 and the lower hood 3 work together to allow more air to flow from the outside of the outer baffle 4, thereby increasing the flow velocity at the outer wall of the windproof cover body 1 to reduce the air pressure, and thus achieving smoke exhaust through Bernoulli's principle.
[0031] In this embodiment of the disclosure, such as Figures 1-4As shown, the outer wall of the windproof cover body 1 has ten elongated openings arranged in a ring, penetrating both the inside and outside. Ten outer baffles 4 and ten inner baffles 5 are located on the outside and inside of these ten elongated openings, respectively. When in use, the windproof cover body 1 can discharge the flue gas in the steel chimney outward through the elongated openings on its outer wall. During this process, the ten outer baffles 4 and ten inner baffles 5 can block the wind and prevent the wind from blowing directly towards the elongated openings, thus playing a windproof role.
[0032] In this embodiment of the disclosure, such as Figures 1-4 and Figure 6 As shown, the outer baffles 4 are all located between the upper hood 2 and the lower hood 3, and two inclined plates are symmetrically arranged on the outer side of each outer baffle 4. The inclined plates symmetrically arranged on the outer side of the outer baffle 4 can also guide the airflow, thereby increasing the flow velocity at the outer side of the long strip opening on the outer wall of the windproof cover body 1 to reduce the air pressure, and then the smoke in the windproof cover body 1 can be drawn out.
[0033] In this embodiment of the disclosure, such as Figures 1-6 As shown, the main body of both the outer baffle 4 and the inner baffle 5 is an L-shaped plate, and the width of both the outer baffle 4 and the inner baffle 5 is twice the width of the elongated opening on the outer wall of the windproof cover body 1. The outer baffle 4 can block rainwater on the outside of the windproof cover body 1 during rainy weather, reducing the amount of rainwater entering the steel chimney through the elongated opening on the outer wall of the windproof cover body 1. If splashing rainwater enters the elongated opening on the outer wall of the windproof cover body 1, the inner baffle 5 will also block this rainwater, and then this rainwater will flow down along the vertical protrusions on the inner baffle 5 into the water collection tank 6.
[0034] In this embodiment of the disclosure, such as Figure 4 As shown, the water collection trough 6 is an annular trough. The outer wall of the windproof cover body 1 is also provided with ten semi-circular holes that penetrate from the inside out. The bottom surface of the semi-circular holes is on the same plane as the bottom inner surface of the water collection trough 6. If splashing rainwater enters the elongated opening on the outer wall of the windproof cover body 1, the inner baffle 5 will also block the rainwater. Then, the rainwater will flow down along the vertical protrusions on the inner baffle 5 into the water collection trough 6. The water in the water collection trough 6 can flow out through the semi-circular holes on the outer wall of the windproof cover body 1, preventing rainwater from flowing down into the steel chimney and causing adverse effects on the boiler.
[0035] Example 2, based on Example 1, such as Figures 1-6As shown, the bottom of the inner baffle 5 is connected to the top of the water collection tank 6. On the side of the inner baffle 5 facing the long strip opening on the outer wall of the windproof cover body 1, there are three vertical protrusions at equal intervals. If splashing rainwater enters the long strip opening on the outer wall of the windproof cover body 1, the inner baffle 5 will also block the rainwater. Then the rainwater will flow down along the vertical protrusions on the inner baffle 5 into the water collection tank 6.
[0036] The working principle of this embodiment is as follows: During installation, the main body 1 of the windproof cover can be fixed to the top of the steel chimney. During use, the main body 1 of the windproof cover can discharge the flue gas in the steel chimney through the elongated opening on its outer wall. The bowl-shaped upper and lower diversion covers 2 and 3 work together to allow more air to flow from the outside of the outer baffle 4, thereby increasing the flow velocity at the outer wall of the windproof cover 1 to reduce the air pressure. This achieves smoke exhaust through Bernoulli's principle. The symmetrically arranged inclined plates on the outside of the outer baffle 4 can also guide the airflow, thereby increasing the flow velocity at the outer side of the elongated opening on the outer wall of the windproof cover 1 to reduce the air pressure. Then, the windproof cover can be installed. The flue gas in the main body 1 is drawn outwards. The outer baffle 4 can block rainwater on the outside of the main body 1 during rainy weather, reducing the amount of rainwater entering the steel chimney through the long strip opening on the outer wall of the main body 1. If splashing rainwater enters the long strip opening on the outer wall of the main body 1, the inner baffle 5 will also block this rainwater. Then, this rainwater will flow down along the vertical protrusions on the inner baffle 5 into the water collection tank 6. The water in the water collection tank 6 can flow outwards through the semi-circular holes on the outer wall of the main body 1, preventing rainwater from flowing down into the steel chimney and causing adverse effects on the boiler.
