[0003] Existing Chinese patent CN220834928U, published on April 26, 2024, discloses a waste gas purification and treatment device, including a movable base. The movable base includes a base plate and a support platform. The support platform is fixedly installed on the upper surface of the base plate. A treatment box is fixedly installed on the support platform. An air intake fan is installed on one side of the treatment box, and an exhaust pipe is provided on the top of the treatment box. A first filter screen and a second filter screen are fixedly installed in the treatment box. A liquid collection shell is also provided at the lower end of the second filter screen. A spray head is installed at the upper end of the first filter screen.

[0004] However, when the above-mentioned waste gas purification device transports waste gas for purification, the waste gas cannot be effectively and evenly dispersed. As a result, when the waste gas passes through the first filter screen and the second filter screen, some of the first filter screen and the second filter screen will be used while some will not be used. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste gas purification device for metal product processing. The waste gas purified by spraying can be uniformly transported through a uniform flow conveyor plate, allowing the gas to be evenly dispersed into the waste gas filter box. This makes the filtration and purification process more uniform and avoids the situation where some areas of the waste gas filter box are not filtered.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste gas purification treatment device for metal product processing, comprising a purification tower box and a bottom mounting plate, wherein the purification tower box is installed and connected to the upper end of the bottom mounting plate, an exhaust pipe is provided in the middle of the upper end of the purification tower box, a waste gas filter box is provided on the inner side of the upper end of the purification tower box, a flow equalization conveying plate is provided below the waste gas filter box on the purification tower box, a purification spray plate is provided at the lower end of the flow equalization conveying plate on the purification tower box, an air inlet pipe is provided on the left side of the lower end of the purification tower box, and a spray purification mechanism is provided on the inner side of the right end of the purification tower box;

[0007] The uniform flow conveying plate includes a metal fixing plate, a connecting sleeve hole, and uniform flow holes. The inner side of the metal fixing plate is provided with multiple uniform flow holes, and the inner right end of the metal fixing plate is provided with a connecting sleeve hole. The metal fixing plate is installed and connected to the spray purification mechanism through the connecting sleeve hole.

[0008] Through the above technical solution: the waste gas from metal product processing can be transported to the purification tower through the air inlet pipe. The spray purification mechanism can draw the purification liquid from the bottom of the purification tower into the purification spray plate. The waste gas is then sprayed and purified through the purification spray plate. After being sprayed and purified, the waste gas from metal product processing can be uniformly transported through the uniform flow conveying plate, so that the gas can be evenly dispersed into the waste gas filter box. This makes the filtration and purification of the waste gas filter box more uniform and avoids the situation where some parts of the waste gas filter box are not filtered. Finally, the purified gas can be discharged into the external environment through the exhaust pipe.

[0009] The present invention is further configured such that the exhaust gas filter box includes a filter plate storage cavity, a box shell, a filter panel and a pipe hole, the filter plate storage cavity is provided inside the box shell, the filter panel is provided on the inner side of the filter plate storage cavity on the box shell, the pipe hole is provided on the inner side of the right end of the box shell, and the box shell is installed and connected to the spray purification mechanism through the pipe hole.

[0010] Through the above technical solutions, the structure of the exhaust gas filter box allows for the transport of gas for purification and processing.

[0011] The present invention is further configured such that the spray purification mechanism includes an upper conveying pipe, an extraction pipe, an extraction pump, a welding panel, and a spray conveying pipe. The extraction pump is installed and connected to the upper end of the welding panel. The inlet end of the extraction pump is provided with an extraction pipe through the welding panel. The outlet end of the extraction pump is provided with a spray conveying pipe. The spray conveying pipe passes through the purification tower box, the uniform flow conveying plate, and the exhaust gas filter box and is installed and connected to the purification spray plate. The lower end of the extraction pipe is installed and connected to the outlet hole of the purification tower box.

[0012] Through the above technical solution, the structure of the spray purification mechanism allows for the purification of liquids through spraying.

[0013] The present invention is further configured such that the purification spray plate includes a hollow spray plate, an exhaust gas conveying trough, a water inlet hole, and a U-shaped spray panel. The upper right side of the hollow spray plate is provided with a water inlet hole, the inner side of the left end of the hollow spray plate is provided with an exhaust gas conveying trough, and the inner side of the exhaust gas conveying trough is provided with a U-shaped spray panel on the hollow spray plate. The hollow spray plate is fixedly connected to the inner side of the purification tower box.

[0014] Through the above technical solutions, the purification spray can be carried out through the structure of the purification spray plate.

[0015] The present invention is further configured such that the exhaust pipe is installed and connected at the highest exhaust port at the top of the purification tower box.

[0016] The above technical solution facilitates gas discharge because the exhaust pipe is installed and connected at the highest exhaust port at the top of the purification tower.

[0017] The present invention is further configured such that the interior of the purification tower box is hollow and a liquid collection tank is provided at the bottom.

[0018] The above technical solution allows for easy gas transport due to the hollow interior of the purification tower and the presence of a liquid collection tank at the bottom, which in turn allows for the storage of purified liquid.

[0019] The present invention is further configured such that the air intake pipe is installed at a position lower than that of the purification spray plate.

[0020] Through the above technical solution: because the installation position of the air intake pipe is lower than that of the purification spray plate, the gas entering through the air intake pipe can be sprayed and purified at the bottom of the purification spray plate before rising.

[0021] The present invention is further configured such that the purification tower box and the bottom mounting plate are connected by welding, and the connection points are aligned.

[0022] The above technical solution allows for secure installation of the purification tower and bottom mounting plate through welding, with the joints aligned to prevent obstruction during use.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. By setting up a uniform flow conveying plate structure, the uniform flow conveying can be achieved. The inner side of the metal fixing plate of the uniform flow conveying plate has multiple uniform flow holes, which can be used to uniformly convey the waste gas.
