[0002] In the process of process wastewater treatment, waste gases containing various pollutants are generated. These waste gases cause serious harm to the environment and human health. The air purification and filtering device for process wastewater treatment is a device specially designed to treat the waste gases generated during the process of process wastewater treatment.

[0003] Some of the current market air purification devices only use simple filter plates, which are difficult to comprehensively and deeply purify the waste gases generated during the process of process wastewater treatment. This makes it possible that they may not achieve the ideal purification effect when dealing with the complex and diverse pollutants in the waste gases. In terms of maintenance, due to factors such as structural design, its maintenance process is often relatively complex. Whether it is the inspection, replacement or cleaning of internal components, it requires a lot of manpower and time costs, which brings certain obstacles to the continuous and stable operation and efficient purification of the device.

[0004] Therefore, aiming at the problems that the above air purification device only uses a simple filter plate, is difficult to comprehensively and deeply purify the waste gases generated by process wastewater treatment, has a complex structural design, a complex maintenance process, and high manpower and time costs, an air purification and filtering device for process wastewater treatment can be designed. The device adopts a multi-stage filtering structure to achieve multi-stage filtering, and at the same time, through the installation plate, it is possible to quickly observe the internal situation of the box body for maintenance operations. Summary of the Utility Model

The purification component includes an electrostatic control console, a pull handle, a filter grid plate, a dust collection plate, an activated carbon layer, a filter net, a first-level frame, a second-level frame and a third-level frame; a filter grid plate for initially filtering larger sundries to prevent these objects from entering the interior of the device is installed at the bottom of the box body, a third-level frame is installed above the filter grid plate, and a dust collection plate for collecting dust in the air and removing solid pollutants in the air is installed inside the third-level frame.

[0007] Preferably, the box body serves as the main structure of the entire device, providing a stable installation space and a protective shell for the purification components. The tightness of the box body ensures that the waste gas is centrally processed inside, preventing the leakage of unpurified gas into the surrounding environment and causing secondary pollution. The filter grid plate can initially filter larger debris such as leaves, paper, and fibers, avoiding these objects from entering the subsequent purification process and preventing blockage of pipelines and damage to equipment. The three-level frame provides stable installation support for the dust collection plate. The dust collection plate collects dust and solid pollutants in the air through electrostatic action.

When installing and disassembling the mounting plate, the operator can easily insert the mounting plate into the square slot or pull it out from the slot by holding the mounting handle. The guide plate is installed inside the box, and its function is to guide the flow direction of the exhaust gas in the box so that the airflow passes through each purification component more evenly. The design of the guide plate can avoid airflow turbulence and short circuit, ensuring that the exhaust gas can fully contact the purification components and improve the purification efficiency.

[0012] Preferably, the exhaust duct includes a support frame, a fan motor, an impeller and an impeller guard; a support frame for providing stable support is installed inside the exhaust duct, and the support frame is installed inside the exhaust duct to provide a stable support structure for the fan motor, impeller and other components.
