Description

Technical Field

[0001] This utility model relates to the field of explosion-proof water tank technology, and in particular to an explosion-proof diesel engine exhaust explosion-proof water tank device. Background Technology

[0002] In industrial production, explosion-proof diesel engines are widely used in hazardous locations such as underground coal mines and petrochemical plants where flammable and explosive gases are present. Improper handling of the high-temperature, high-pressure exhaust generated during their operation can not only lead to serious safety accidents such as fires and explosions, but also produce significant noise, impacting the working environment. Therefore, developing a device that can effectively treat explosion-proof diesel engine exhaust, while also providing noise reduction, cooling, and explosion-proof functions, is of great significance for ensuring production safety and improving the working environment. This has spurred the research and development of an explosion-proof diesel engine exhaust explosion-proof water tank device.

[0003] In existing technologies, some devices for treating exhaust gas from explosion-proof diesel engines employ simple pipe connections and a single physical filtration method. These devices use filter elements or screens to filter impurities in the exhaust gas and cool it through natural heat dissipation or a simple air-cooling structure. The main principle is to use the pore size of the filter element to block impurities and rely on natural air convection to remove heat, preventing safety issues caused by excessively high exhaust temperatures.

[0004] However, existing devices struggle to effectively guide exhaust gas into a uniform airflow, leading to the formation of eddies and localized high-temperature areas during the exhaust process. Once eddies form, they not only impair heat dissipation, causing excessively high temperatures in localized areas and increasing the risk of explosion, but also exacerbate noise due to unstable airflow. Simultaneously, the lack of effective sealing and containment measures means the risk of flame backflow remains, making it difficult to fundamentally guarantee the safety of equipment operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an explosion-proof diesel engine exhaust explosion-proof water tank device, which aims to improve the problem that existing devices are unable to effectively guide the exhaust to form a uniform airflow, resulting in the generation of eddies and local high-temperature areas during the exhaust process. This not only affects the heat dissipation effect, but also causes the local temperature to be too high, increasing the risk of explosion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof diesel engine exhaust explosion-proof water tank device, comprising a water tank sidewall one, a water tank sidewall two welded to one side of the outer wall of the water tank sidewall one, a top cover plate welded to the top of the water tank sidewall one, an air inlet concave flange fixedly connected to the outer wall of the water tank sidewall one, an air inlet short pipe fixedly connected to one side of the outer wall of the air inlet concave flange, a muffler housing fixedly connected to the outer wall of the air inlet short pipe, an elliptical end cap two fixedly connected to the top of the muffler housing, an elliptical end cap one fixedly connected to the bottom of the muffler housing, a vertical guide plate fixedly connected to the upper side of the inner wall of the muffler housing, an exhaust port concave flange fixedly connected to the top of the elliptical end cap two, a drain pipe fixedly connected to the bottom of the water tank sidewall one, and a filter assembly provided on the lower side of the inner wall of the muffler housing;

[0012] Furthermore, the inner surface of the mounting hole is used for welding an M8 nut to secure the water tank cover.

[0013] Furthermore, the inner diameter of the first porous sound-absorbing plate is 12 and the hole spacing is 20; the inner diameter of the second porous sound-absorbing plate is 15 and the hole spacing is 22; and the inner diameter of the third porous sound-absorbing plate is 20 and the hole spacing is 26.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 6 This utility model provides an embodiment of an explosion-proof diesel engine exhaust explosion-proof water tank device, including a water tank side wall 1, a second water tank side wall 2 welded to one side of the outer wall of the first water tank side wall 1, a top cover plate 4 welded to the top of the first water tank side wall 1, an air inlet concave flange 5 fixedly connected to the outer wall of the first water tank side wall 1, an air inlet short pipe 10 fixedly connected to one side of the outer wall of the air inlet concave flange 5 to guide the high-temperature and high-pressure exhaust gas discharged from the diesel engine to smoothly enter the muffler housing 6, the muffler housing 6 fixedly connected to the outer wall of the air inlet short pipe 10, and a top cover plate 4 welded to the top of the muffler housing 6. Elliptical head 2 8, elliptical head 1 7 is fixedly connected to the bottom of the silencer housing 6, vertical guide plates 11 are fixedly connected to the upper side of the inner wall of the silencer housing 6, six plates per group, each 5 mm thick, are fixed to the upper side of the inner wall of the silencer housing 6, and an exhaust port concave flange 15 is fixedly connected to the top of the elliptical head 2 8, which is a gas outlet device that discharges the gas after water sealing treatment to achieve the final discharge of exhaust gas, and a drain pipe 18 is fixedly connected to the bottom of the water tank side wall 1, which is used to discharge the water in the water tank, and a filter assembly is provided on the lower side of the inner wall of the silencer housing 6;

[0028] The filter assembly includes a porous silencer plate 9, a porous silencer plate 901, and a porous silencer plate 902. The porous silencer plate 9, the porous silencer plate 901, and the porous silencer plate 902 are fixedly connected from top to bottom to the lower side of the inner wall of the elliptical head 8. With different inner hole diameters and hole spacing, the exhaust gas that has been initially treated by the vertical guide plate 11 is further filtered and silenced to reduce noise and impurities in the exhaust gas.

[0029] Specifically, the high-temperature and high-pressure exhaust gas first enters the muffler housing 6 smoothly through the short intake pipe 10 and under the guidance of the concave flange 5 at the intake port. Inside the muffler housing 6, six vertical guide plates 11, each 5 mm thick, are fixedly installed in a specific layout. The guide plates can change the flow direction of the exhaust gas, guiding it to form a uniform airflow distribution inside the muffler housing 6, effectively avoiding the generation of eddies and the formation of local high-temperature areas. After the exhaust gas has undergone preliminary treatment by the muffler, it enters the main body of the water tank. The water tank contains a certain level of water and is reinforced with internal bracing using bent profiles of the same material as the tank body, enhancing the water tank's resistance to deformation under exhaust pressure. The exhaust gas is forced to pass through the water layer in the water tank, and the high-temperature gas and water undergo sufficient heat exchange, thereby achieving cooling. At the same time, the water layer acts as a seal, blocking any possible flame backflow and achieving explosion-proof purpose. The gas that has undergone water sealing treatment is finally discharged through the exhaust port concave flange 15 at the top of the elliptical end cap 2 8.

[0030] Reference Figure 1 , Figure 2 ,and Figure 5 A base plate 3 is provided at the bottom of the water tank side wall 1. A water tank fixing seat 19 is fixedly connected to the outer wall of the water tank side wall 1. A square nut 20 is provided inside the water tank fixing seat 19.

A second pipe clamp 17 is fixedly connected to one side of the outer wall of the water tank side wall 1. A stamped elbow 14 is fixedly connected to the other side of the outer wall of the water tank side wall 1. On the other side of the wall, by changing the direction of the pipe, the device is seamlessly connected with the external pipe in terms of spatial layout, ensuring smooth gas transmission. Mounting hole 2 13 is used to weld DN20 internal thread pipe joints. Mounting hole 1 12 is used to weld M8 nuts to fix the water tank cover. The inner diameter of the perforated silencer plate 1 9 is 12 and the hole spacing is 20. The inner diameter of the perforated silencer plate 2 901 is 15 and the hole spacing is 22. The inner diameter of the perforated silencer plate 3 902 is 20 and the hole spacing is 26. The vertical guide plates 11 are arranged in groups of six on the inner wall of the silencer housing 6, and their thickness is 5 mm.

[0031] Specifically, the base plate 3 and water tank mounting base 19 at the bottom of the device provide stable support for the entire equipment. The square nut 20 is designed to facilitate fixing the device to the workplace. The top cover plate 4 of the device has mounting holes 12 and 13. Mounting hole 12 is used to weld M8 nuts to fix the water tank cover, and mounting hole 13 is used to weld DN20 internal thread pipe joints to realize pipeline connection. Pipe clamps 16, 17, and stamped elbows 14 ensure good matching between the device and external pipelines. The top of the box is also equipped with a lifting ring, which greatly facilitates the handling of the device. During the manufacturing process of the device, the threaded holes of all inlet and outlet flanges must be precisely matched with the dimensions of the on-site equipment and undergo a 0.2MPa water pressure test to ensure the sealing of the device. In addition, the internal reinforcing rib design enhances the strength of the box and prevents deformation. The interface of the level gauge and thermometer can be customized according to actual needs to meet the monitoring of the liquid level and temperature inside the water tank without affecting the installation of other components.

[0032] Working principle: When the diesel engine exhaust enters the device, it first passes through the short intake pipe 10 and then through the concave flange 5 of the intake port into the muffler housing 6. After entering the muffler housing 6, the exhaust will encounter the internally fixed vertical guide plates 11. These guide plates are in groups of six and are 5 mm thick. Their function is to guide the exhaust to form a uniform airflow distribution inside the muffler housing 6, avoiding the generation of eddies and local high temperature areas. After passing through the muffler, the exhaust enters the main body of the water tank. The water tank is filled with water at a certain level. The water tank is also reinforced with internal bracing by bending profiles of the same material as the tank body to prevent the water tank from deforming when subjected to exhaust pressure. In the water tank, the exhaust is forced through the water layer, which cools the high temperature gas. Due to the sealing effect of the water, any possible flame backflow is blocked, thereby achieving the purpose of explosion prevention. Finally, the gas treated by the water seal is discharged from the exhaust port concave flange 15 at the top of the elliptical head 28.

[0033] In addition, the chassis 3 and the water tank mounting base 19 provide stable support, the square nut 20 facilitates the fixing of the device, the mounting hole 12 and the mounting hole 23 are used for fixing the water tank cover and connecting the pipeline, respectively, the pipe clamp 16, the pipe clamp 2 and the stamped elbow 14 ensure the matching of the external pipeline, and the top of the box is equipped with a lifting ring for easy handling. During the manufacturing process, the threaded holes of all inlet and outlet pipe flanges must match the size of the on-site equipment and undergo a 0.2MPa water pressure test to ensure sealing. The internal reinforcing rib design enhances the strength of the box and prevents deformation. The interface of the level gauge and the thermometer is customized according to requirements to ensure that it does not affect the installation of other components.
