Which of the following would most likely utilize a particulate control device?

  1. a. a Vacuum Cleaner
    b. a factory smokestack
    c. a laundry dryer
    d. all of the above

Answer

The answer is D. all of the above

A vacuum cleaner is used to create a partial vacuum to suck up dust and dirt. It, indeed, has a function as a particulate control device. It is also known as a sweeper or Hoover. This device uses an air pump to do its role. The dust is then collected using a dust-bag or a cyclone for later disposal.

A factory smokestack is a stack that is used to discharge smoke into desirable high level. Without smokestack, the smoke, which contains dust, will be exposed in a lower level. It can harm the low ambient air and possibly contaminate the low level of air where people do common activities.  By lifting up the smoke disposal using the factory smokestack, it can reduce the dust exposed in public area. Moreover, a smoke stack is sometimes also equipped with particulate filter devices.

A laundry dryer does not have a direct function as a particulate control device. However, it can reduce the amount of particulate once the laundry is drying under the sun with particulate expose everywhere.

Thus, therefore the appropriate answer is D. All of the above.
