Description

Technical Field

[0001] The utility model relates to the field of smoke emission chimneys, in particular to a windproof and waterproof device for a heating furnace chimney. Background Art

[0002] Because the flue gas discharged from the heating furnace chimney contains a large amount of water vapor, when the water vapor cools, it combines with carbon dioxide, other carbon oxides, and nitrogen oxides in the flue gas to form acidic condensate such as carbonic acid and sulfuric acid. As a result, equipment around the chimney is often corroded, rusted, or even damaged by the dripping acidic condensate, which not only damages the environment but also causes economic losses.

[0003] For this reason, environmental protection requires that flue gas be discharged at a higher altitude. The wind speed at high altitudes is greater, and the wind force and direction are unstable, which makes the pressure at the chimney mouth unstable, causing pulse back pressure, which in turn causes pressure fluctuations in the furnace and fluctuations in the air-fuel ratio, thus affecting the combustion efficiency of the burner.

[0004] At present, chimney outlets are either directly facing the air or simply equipped with a conical chimney cap to prevent rain, but the effects of proper treatment of chimney outlets on equipment and the environment are not taken seriously.

[0005] In order to overcome the above-mentioned defects, the present invention has made beneficial improvements. Utility Model Content

[0009] Furthermore, the diameter of the lower circular surface of the W-shaped rainproof cap is greater than 1.2 times the diameter of the chimney outlet to prevent rainwater from entering the chimney. The condensed water formed by the condensation of flue gas on the bottom surface of the W-shaped rainproof cap converges along the W-shaped inclined surface to the line along the lower circular surface of the W-shaped rainproof cap, and flows into the water collection tray along the cyclone support plate;

[0010] Furthermore: a plurality of rain cap drain holes are provided along the periphery of the lower circular surface of the W-shaped rain cap;

[0011] Furthermore: the outer diameter of the water collecting tray is greater than 1.5 times the maximum diameter of the W-shaped rainproof cap, and the water collecting tray has a flat bottom or a V-shaped bottom;

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Reference to the embodiments of the present invention Figure 1As shown, a windproof and waterproof device for a heating furnace chimney includes a W-shaped rainproof cap 1, a water collecting tray 3 and a cyclone support plate 2 connecting them.

[0023] The water collecting tray 3 is a disc-shaped container that can hold and collect condensed water and rainwater. The upper end is open and is welded upwardly and sealed below the outlet of the chimney 6 so that the outlet of the chimney 6 is higher than the upper edge of the water collecting tray 3 to prevent the liquid in the water collecting tray 3 from entering the chimney 6.

[0024] The W-shaped rain cap 1 is a disc-shaped cover with a circular outer shape and a cross-section through the center that forms a W shape. The diameter of the lower circular surface of the W-shaped rain cap 1 should be at least 1.2 times larger than the chimney 6 outlet to prevent rainwater from entering the chimney 6. Condensate formed by flue gas condensing on the bottom surface of the W-shaped rain cap 1 can flow along the inclined surface of the W-shaped rain cap 1 to the line along the lower circular surface of the W-shaped rain cap 1 and flow along the cyclone support plate 2 into the water collection tray.

[0025] A plurality of rain cap drain holes 8 are provided around the lower circle of the W-shaped rain cap 1 , so that rainwater from the depression on the upper side of the W-shaped rain cap 1 can flow along the rain cap drain holes 8 into the water collecting tray 3 .

[0026] The outer diameter of the water collection tray 3 should be 1.5 times greater than the maximum diameter of the W-shaped rain shield 1. It can have a flat bottom, a V-shaped bottom, or other suitable water-holding shape. It can completely catch rainwater and condensation from the W-shaped rain shield 1, as well as condensation blown off by the wind, preventing acidic condensation from being dispersed by the wind and corroding underlying equipment or affecting the surrounding environment.

[0027] The cyclone support plate 1 is a plurality of arc-shaped steel plates, which are evenly distributed around the circumference of the lower circle of the W-shaped rainproof cap 1. One end is welded to the lower circle of the W-shaped rainproof cap 1, and the other end is welded to the water collecting plate 3 to form a shape like a wind wheel. Figure 2 and Figure 3 As shown, when the wind blows from any direction and passes through the cyclone support plate, the curved fan blades will guide the wind to the periphery of the chimney, rotate inside the windproof cap, and be discharged in other directions, thereby not affecting the discharge of flue gas, making the combustion of furnace fuel stable and improving combustion efficiency.

[0028] The heat pipe 4 is a closed, evacuated tube filled with a heat-conducting medium. One end of the tube is inserted into the chimney, and the other end is welded to the periphery of the water collection pan 3. When the heat pipe in the chimney 6 comes into contact with the flue gas, it absorbs the flue gas' heat and transfers it to the water collection pan 3 via the heat-conducting medium. This cools the flue gas while maintaining a constant temperature around the pan 3, preventing moisture from condensing and dripping around the pan and corroding surrounding equipment.

[0029] There are multiple heat pipes 4, which are evenly distributed and welded around the water collecting tray 3 of the chimney 6. Figure 2 It is both a heat transfer element and a support for the water collection pan.

[0030] The water pipe 5 is a guide pipe for the accumulated water in the water collecting pan 3. One end of the water pipe is connected to the drainage hole 7 at the bottom of the water collecting pan 3, and the other end is led to the groove at the bottom of the chimney 6, and flows to the sewage treatment equipment for centralized treatment.

[0031] The above embodiment is only one embodiment of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and all such modifications and improvements fall within the scope of protection of the present invention.
