Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust systems, in particular to a rainproof smoke exhaust system applied to equipment such as generators. Background Art

[0002] Generator sets are commonly used in fields such as infrastructure construction, communication stations, emergency rescue and disaster relief, etc. For example, standby diesel generator sets need to be installed in places such as the building groups in the CBD areas of major cities and data center construction projects. Such generator sets are equipped with smoke exhaust systems, and the smoke exhaust system products in such places have relatively high requirements for aesthetics. Generally, a rainproof cap is set at the smoke exhaust port at the top of the chimney of the traditional smoke exhaust system to prevent rainwater from entering the chimney and causing equipment damage, such as an internal chimney rainproof cap disclosed in the Chinese utility model patent CN208431792U. However, no matter how such chimneys are designed, the rainproof cap can be seen from the outside, and the rainproof cap will be blackened by the flue gas, affecting the aesthetics. And if the rainproof cap is set inside the chimney, a relatively complex water guiding structure needs to be designed, otherwise the rainwater will still enter along the chimney. Summary of the Utility Model

[0003] Aiming at the defects existing in the prior art, the utility model provides a generator set chimney with a simpler structure, good rainproof effect, more neat and beautiful appearance, and an internal rainproof structure.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: A generator set chimney with an internal rainproof structure includes a chimney. The chimney includes a horizontal section and a vertical section. The horizontal section is connected to the muffler of the generator set. It is characterized in that: a water baffle and a drain hole are provided at the bottom of the horizontal section of the chimney. The drain hole is located in front of the water baffle to communicate the inside and outside of the chimney; the water baffle extends upward and forward obliquely, and there is a smoke exhaust passage between the top end of the water baffle and the top wall of the horizontal section of the chimney.

[0005] Preferably, the water baffle forms an angle of 50 - 70 degrees, such as 60 degrees, with the horizontal section of the chimney, so as to achieve the best balance between the water baffle effect and the smoke exhaust smoothness.

[0006] Preferably, the water baffle is made of stainless steel material, and its top end is a flat structure; the thickness of the water baffle is 3 - 5 mm, and the height is 20 - 50 mm.

[0007] Further, the drain hole is a tapped hole with a diameter of 1 - 3 inches, and it is arranged at a position close to the front end of the water baffle.

[0008] Further, a protective net is provided at the opening at the top end of the vertical section of the chimney. The protective net is embedded inside the chimney; the protective net is made of stainless steel material.

[0009] Furthermore, the chimney is installed in the smoke exhaust shaft. The vertical section of the chimney extends upward along the smoke exhaust shaft, and a fixing bracket is arranged in the smoke exhaust shaft to fix the chimney.

[0010] Furthermore, a smoke outlet pipe is arranged at the front end of the muffler, and the tail end of the horizontal section of the chimney is fixedly connected to the smoke outlet pipe through a flange.

[0011] Furthermore, the generator set is connected to the muffler through a flexible corrugated pipe and a connecting pipe with a chimney heat insulation layer.

[0012] Furthermore, an exhaust gas processor is arranged between the connecting pipe and the muffler to process the flue gas entering the muffler.

[0013] By arranging a water baffle and a drain hole at the horizontal section of the bottom of the chimney, the present utility model can prevent rainwater from entering the engine, achieving the rain-proof function. Thus, the rain-proof cap at the smoke outlet of the traditional chimney can be removed, making the chimney more beautiful and tidy, and it is easier to achieve better coordination with the building style. At the same time, the structure is relatively simple, the rain-proof effect is good, the material components are reduced, and the project cost and installation cost can be effectively saved. In addition, the product is made more compact, more chimneys can be arranged side by side in a limited space, reducing the occupied roof space, and it is particularly suitable for the application scenario where multiple diesel generator set chimneys are densely arranged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In this embodiment, with reference to Figure 1 、 Figure 2 and Figure 3, the chimney of the generator set with built-in rainproof structure includes a chimney 1, which consists of a horizontal section 11 and a vertical section 12. The horizontal section 11 is connected to the muffler 3 of the generator set 5; a water baffle 13 and a drain hole 14 are provided at the bottom of the horizontal section 11 of the chimney 1. The drain hole 14 is located in front of the water baffle 13 to connect the inside and outside of the chimney 1. The rainwater entering the chimney will be blocked by the water baffle 13 and discharged through the drain hole 14 to prevent it from entering the interior of the generator set; the water baffle 13 extends upward and forward obliquely, and there is a smoke exhaust passage between the top end of the water baffle 13 and the top wall of the horizontal section 11 of the chimney 1, and the flue gas is discharged outward through the smoke exhaust passage.

[0019] The water baffle 13 forms an angle of 50 - 70 degrees, such as 60 degrees, with the horizontal section 11 of the chimney, so as to achieve the best balance between the water blocking effect and the smoothness of smoke exhaust. If the angle is too small or too large, a water baffle 13 with a larger size is required to achieve sufficient water blocking effect, and it will occupy more space inside the chimney 1, thus affecting the efficiency of smoke exhaust.

[0020] The water baffle 13 is made of stainless steel material, such as SS304, and its top end is a flat structure; the thickness of the water baffle is 3 - 5 mm, such as 4 mm; the height is 20 - 50 mm, such as 30 mm.

[0021] The drain hole 14 is a tapped hole with a diameter of 1 - 3 inches, such as 2 inches, and it is set at a position close to the front end of the water baffle 13. Through the drain hole 14, it is convenient to introduce the rainwater entering the chimney 1 into the rainwater well in the later stage.

[0022] A protective net 15 is provided at the opening at the top end of the vertical section 12 of the chimney 1. The protective net 15 is embedded inside the chimney 1 and cannot be seen from the outside, which will not affect the appearance of the chimney 1; the protective net is made of stainless steel material and can prevent mice, birds, etc. from entering the interior.

[0023] The chimney 1 is installed in the smoke exhaust well 2, and the vertical section 12 of the chimney 1 extends upward along the smoke exhaust well 22. A fixing frame 21 is provided in the smoke exhaust well to fix the chimney 1.

[0024] A smoke outlet pipe 31 is provided at the front end of the muffler 3, and the tail end of the horizontal section 11 of the chimney 1 is fixedly connected to the smoke outlet pipe 31 through a flange 4.

[0025] The generator set 5 is connected to the muffler 3 through a flexible corrugated pipe 6 and a connecting pipe 7 with a chimney heat insulation layer, which can improve the flexibility of the installation position.

[0026] An exhaust gas processor 8 is provided between the connecting pipe 7 and the muffler 3 to process the flue gas entering the muffler 3.

[0027] The above has made a detailed description of the present utility model. As described above, it is only the preferred embodiment of the present utility model, and the scope of implementation of the present utility model cannot be limited. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present utility model.
