Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to an air purification device for a work cabin. Background Technology

[0002] With advancements in technology, especially in specialized environments such as aerospace, diving, and sealed workshops, the air quality inside work chambers is crucial to the health of personnel and the smooth operation of tasks. Air purification systems, as a key component in ensuring air quality, are particularly important in enclosed work chamber environments. Enclosed work chambers typically lack external air circulation and are in a highly sealed state for extended periods, easily leading to the accumulation of harmful substances in the air, such as bacteria, viruses, dust, toxic gases, and odors. To ensure the health and safety of personnel, efficient air purification equipment must be used to remove these pollutants promptly.

[0003] Existing air purification devices mostly adopt a single purification method, such as relying on a single filter, chemical adsorption material or photocatalytic technology. They often do not fully consider modularity and maintainability, resulting in difficulties in equipment maintenance and replacement, high operating costs, and poor sealing. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

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.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a working chamber air purification device, including a shell 1, a purification module, a fan 3, a sealing valve 4, and a controller 5. The shell 1 has two units connected in a detachable manner to form a cuboid shape. The purification module includes an electret module 2 and an adsorption module 17. The electret module 2 is located on the left side inside the shell 1. Several adsorption modules 17 are distributed at equal intervals from top to bottom on the right side of the electret module 2. The fan 3 is located on the right side of the adsorption module 17. The sealing valve 4 is located on the outside of the shell 1. The controller 5 is located at the bottom of the sealing valve 4.

The electret filter element 7 is located inside the rhombus-shaped protective mesh 8. The electret is used as the filter material. Through the mechanical capture mechanism of inertial collision, interception, and diffusion, and the Coulomb force of the charged fiber (electret), aerosols and suspended particulate matter are filtered out.

[0026] The adsorption module 17 is provided with a sealing gasket 9 on the outside, and an adsorption material layer 10 is filled inside the sealing gasket 9. The adsorption material layer 10 is impregnated carbon. The adsorption module contains 5 carbon units and uses special impregnated carbon as the adsorption material. It removes harmful gases such as benzene and hydrogen sulfide through purification principles such as physical adsorption and chemical adsorption.

Its working principle is: the motor 18 rotates to drive the connecting rod 15, which in turn drives the several louvers to complete the opening and closing of the valve. The degree of opening and closing is controlled by the limit sensor.

[0028] Working principle: The opening and closing of the device is controlled by controller 5. When the device is working, the airtight valve 4 is open, the fan 3 runs, and the polluted air first passes through the electret module 2 to filter out aerosols and suspended particles, and then passes through the adsorption module 17 to remove harmful gases such as benzene, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, ozone, ethanolamine, xylene, 1,2-dichloroethane, chloroform, formaldehyde, total hydrocarbons, methanol, and ammonia. The clean air is then delivered into the chamber. At the same time, the device's operating status is displayed and uploaded, and commands issued by the upper-level control system are received and responded to. When the device stops working, the fan 3 stops running and the airtight valve 4 closes.
