Which pollution control device operates similarly to a vacuum cleaner and can remove very fine particles?

The device that operates similarly to a vacuum cleaner and is capable of removing very fine particles is a bag house. A bag house functions as a filtration system, where air containing dust and particulates is drawn through fabric filter bags. As the air passes through these bags, the particles are trapped while the cleaned air continues through. This process is effective for separating fine particles from gases or air streams, which aligns with the vacuum cleaner analogy, as both systems are designed for suction and filtration.

In contrast, other devices like a gravity cyclone and centrifugal cyclone primarily rely on centrifugal force to separate particles from air or gas streams, which may not be as effective for very fine particles. A scrubber is designed for removing gases or vapors and often involves a liquid medium, which also doesn't align with the operation of a vacuum cleaner. Therefore, the bag house is the most appropriate choice as it both removes fine particulates and operates similarly to a vacuum cleaner in its mechanics.
