Description

An air purification device for dust-free workshop

Technical Field

The utility model relates to the technical field of air purification equipment, and more specifically, to an air purification equipment used in a dust-free workshop.

Background Art

A dust-free workshop generally refers to a clean room. A clean room is a well-enclosed space where air cleanliness, temperature, humidity, pressure, noise and other parameters are controlled as needed. Air purification equipment is used in the dust-free workshop to filter out or kill air pollutants and effectively improve air cleanliness.

The air purification equipment mainly includes structures such as an outer shell, an air inlet, an inner liner and a pipeline. The inner liner is installed inside the outer shell. The air purification equipment sucks and purifies the air in the area through the inner liner. The inner liner is connected to the pipeline connected to the outside air through the pipeline to achieve the purification of the dust-free workshop. The air inlet is fixedly installed on one side of the outer shell, and its opening is used to realize the exchange of air inside and outside the device.

However, since the relative position of the air inlet will be fixed after the device is installed, the device can only suck, purify and interact with the air in the workshop from the side where the air inlet is located. In addition, the air in the clean room itself does not have the ability to circulate, which makes it difficult for the device to suck and purify the area behind the air inlet. Based on the above problems, we provide an air purification device for clean rooms.
