Abstract

This invention relates to a portable odor scrubber system that is inserted into a sewer manhole or lift station where vaporous odors are prone to escape into the external environment. The invention controls such odors which may be caused by hydrogen sulfide, ammonia, mercaptan and other vapors which smell bad and can pose a severe health hazard. The invention has an automatic gas sensor trigger mechanism to control a fan to pull the noxious fumes through a series of scrubbers and to discharge treated air into the environment. Scrubber units may be easily replaced as well as designated to treat different environmental conditions. The invention can also store and transmit gas data information to an offsite location to monitor conditions where the portable odor scrubber system is located.

Claims17

Dependent claims

A device to be nested inside a manhole for removing harmful gas and odors entrained in air residing downhole comprising,

a filter module having a filter module top and a filter module bottom, said filter module bottom having a plurality of apertures and a filtration media located intermediate said filter module top and said filter module bottom,
a fan module having a fan module top and a fan module bottom, said fan module top having a fan centrally mounted thereon, said fan further having a center passage,
a power module having a power module top and a power module bottom, said power module having a center passage,
said power module bottom removably connected to said fan module top,
and said fan module bottom removably connected to said filter module top, whereby
when said fan is actuated, a pressure differential causes the harmful gas and odors to enter said filter module through said plurality of apertures, the harmful gas and odors are removed as they pass through said filter media cleaning the air, and the then cleaned air passes through said fan module center passage and further through the power module central passage, where the cleaned air exits into the environment.

3 more elements

A device to be nested inside a manhole for removing harmful gas and odors entrained in air residing downhole comprising,

a fan module,
a filter module, said filter module having filtration substances housed within disposable cartridges,
an air pathway interconnecting said disposable cartridges and said fan module,
said filter module having gas inlet holes integral with said air pathway,
said air pathway having an exhaust flute,
said device having a power module to power a fan in said air pathway of said fan module, whereby
said fan creates a low pressure zone causing said harmful gas and odors to pass through said filtration substances removing said harmful gas and odors from the air and further causing the air to be exhausted into the environment through said air pathway.
