Description

Technical Field

[0001] This utility model relates to the field of marine machinery parts production technology, and in particular to a waste gas treatment device for marine machinery parts production. Background Technology

[0002] With increasing global awareness of environmental protection, governments worldwide have introduced a series of stringent environmental regulations to limit industrial emissions that pollute the atmosphere and water bodies. Waste gas generated during the production of ship machinery parts, if discharged directly without treatment, poses a serious threat to the environment and human health. Therefore, developing effective waste gas treatment devices to meet environmental regulations has become an urgent need for ship machinery parts manufacturers, thus requiring the design of a waste gas treatment device for ship machinery parts production.

[0003] To address this, patent CN208771147U discloses a height-adjustable exhaust gas treatment device for automotive parts production. The device includes a workbench with a work plate, a cooling box, and a purification device fixedly connected from left to right. An exhaust pipe connects the cooling box and the purification device, and an exhaust fan is installed inside the exhaust pipe. A corrugated suction pipe is fixedly connected to the end of the cooling box away from the exhaust pipe. A threaded cylinder with an open top is provided between the work plate and the cooling box. The threaded cylinder is rotatably connected to the workbench via a first bearing, which is fixedly located inside the workbench. A threaded rod is threadedly connected inside the threaded cylinder, with the end of the threaded rod away from the workbench passing through the open end of the threaded cylinder and extending upwards, and is fixedly connected to a collar. This invention allows for convenient adjustment of the position of the corrugated suction pipe according to the processing location, enabling efficient absorption of exhaust gas and improving the purification effect of the purification device.

[0004] Although the exhaust gas treatment device for automobile parts production mentioned above can efficiently absorb exhaust gas during use, the cooling cotton cloth used for pre-filtering the gas is easily damaged and inconvenient to replace due to long-term high-temperature corrosion. Therefore, it is necessary to design an exhaust gas treatment device for marine machinery parts production. Utility Model Content

[0005] The purpose of this utility model is to provide a waste gas treatment device for the production of marine machinery parts, in order to solve the defects of the existing waste gas treatment devices for marine machinery parts production, which use cooling cotton cloth for pre-filtering the gas, which is easily damaged and inconvenient to replace due to long-term high temperature corrosion.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste gas treatment device for marine machinery parts production, including a base frame;

[0007] An air intake assembly is fixed to the top of the base frame;

[0008] The intake assembly has a pre-treatment structure inside. The pre-treatment structure includes mounting seats fixed to both sides inside the intake assembly. Each mounting seat has a filter box inside. Each filter box has a pre-filter layer inside. A cover plate is snapped onto one side of each filter box.

[0009] A cooling structure is provided on one side of the base frame, a processing component is provided on one side of the cooling structure, and a filter structure is fixedly installed on one side inside the processing component.

[0010] Furthermore, the air intake assembly includes a processing box, a door panel, an air intake pipe, and a cover. The processing box is fixed to the top of the base frame, and a cover is provided at the top of the processing box. An air intake pipe is fixed to one side inside the processing box, and a door panel is provided on one side of the bottom of the processing box.

[0011] Furthermore, the mounting bases are symmetrically distributed on both sides of the processing box, and the pre-filter layer is a metal wire mesh.

[0012] Furthermore, the cooling structure includes a water tank, an air outlet pipe, a cooling pipe, a support plate, and an air inlet pipe. The water tank is located on one side of the base frame. Support plates are evenly fixed on the inner wall of the bottom of the water tank. Cooling pipes are fixed to the top of each support plate. An air outlet pipe is fixed to one end of the cooling pipe, and an air inlet pipe is fixed to the other end of the cooling pipe.

[0013] Furthermore, the top end of the air outlet pipe extends to the outside of the water tank and is fixedly connected to the top end of the treatment assembly, while the top end of the air inlet pipe extends to the top of the treatment chamber.

[0014] Furthermore, the processing component includes a top plate, an air inlet, and a protective box. The protective box is located on one side of the water tank, and the top plate is located at the top of the protective box. An air inlet is provided inside the top plate.

[0015] Furthermore, the filtration structure includes a filter box, a second filter layer, a partition, a first filter layer, and a protective plate. The filter box is fixedly installed on the inner wall of one side of the protective box. The second filter layer is provided on the side of the filter box near the water tank. A partition is provided on one side of the second filter layer. The first filter layer is provided on one side of the partition. The protective plate is snapped onto the outer wall of the filter box near the first filter layer.

[0016] Furthermore, both the second and first filter layers are activated carbon layers.

[0017] The present invention provides a waste gas treatment device for the production of marine machinery parts, the advantages of which are:

[0018] By incorporating a pre-treatment structure, the cover plate can intercept obvious impurities and waste in the exhaust gas through pre-filtration. Subsequently, the pre-filtration layer can further filter and intercept small particles and impurities in the exhaust gas, ensuring that obvious impurities in the exhaust gas are fully treated and preventing blockage of subsequent pipelines. At the same time, the cover plate and filter box are interlocked, which facilitates cleaning and treatment of the inside of the filter box and the pre-filtration layer, and facilitates recycling. This device has the function of facilitating pre-filtration of exhaust gas, improving the convenience of using the exhaust gas treatment device for marine machinery parts production.

[0019] By incorporating a cooling structure, the residence time of exhaust gas in cold water can be increased through the swirling action of the cooling pipe, ensuring that the exhaust gas with heat can be cooled down smoothly and preventing high-temperature gas from damaging subsequent components. After the heat in the exhaust gas is transferred to the water, it can be recovered and reused through the water. This enables the device to efficiently cool cold water and improves the convenience of using the exhaust gas treatment device for ship machinery parts production.

[0020] By incorporating a filtration structure, the dual filtration of the first and second filtration layers ensures efficient subsequent treatment of the exhaust gas, guaranteeing that the exhaust gas is discharged only after meeting emission standards. This enables the device to perform dual filtration of exhaust gas, thereby improving the working efficiency of the exhaust gas treatment device for marine machinery parts production.

The pre-treatment structure 3 includes mounting seats 31 fixed to both sides inside the air intake assembly 2. A filter box 32 is provided on the inner side of each mounting seat 31. A pre-filter layer 33 is provided on the inner side of each filter box 32. A cover plate 34 is snapped onto one side of each filter box 32. The mounting seats 31 are symmetrically distributed on both sides of the processing box 21. The pre-filter layer 33 is a metal wire mesh.

[0030] An external power supply is connected to an external suction fan or blower at one end of the suction pipe 23 to draw the exhaust gas into the treatment box 21. The exhaust gas then passes through the filter holes inside the cover plate 34 and reaches the inside of the filter box 32. The filter box 32 is a metal wire mesh with a smaller aperture than the filter holes inside the cover plate 34. This mesh can block and filter impurities and particles in the exhaust gas, preventing the exhaust gas from clogging the cooling pipe 43 after entering it.

[0031] Reference Figure 1 , Figure 3 and Figure 5A cooling structure 4 is provided on one side of the base frame 1. The cooling structure 4 includes a water tank 41, an air outlet pipe 42, a cooling pipe 43, a support plate 44, and an air inlet pipe 45. The water tank 41 is located on one side of the base frame 1.

The top end of the air inlet pipe 45 extends to the top of the processing box 21.

[0032] The bottom of the water tank 41 is filled with cold water, and the cooling pipe 43 is immersed in the cold water. The exhaust gas enters the cooling pipe 43 through the air inlet pipe 45 and flows inside the cooling pipe 43, which can increase the residence time of the exhaust gas in the cold water and improve the cooling effect of the exhaust gas.

[0033] Reference Figure 1 , Figure 4 and Figure 5 A processing component 5 is provided on one side of the cooling structure 4. The processing component 5 includes a top plate 51, an air inlet 52, and a protective box 53. The protective box 53 is located on one side of the water tank 41.
