Aspects to facilitate dust collection are disclosed. In one aspect, a chute provides a dust seal between a bulk bag of material and a silo loading hatch. Here, the dust seal comprises a first seal between a first end of the chute and the bulk bag, and a second seal between a second end of the chute and the silo loading hatch. In another aspect, a collapsible chute is extended between a silo loading hatch and a discharge chute of a bulk bag such that the collapsible chute forms a dust seal between the silo loading hatch and the bulk bag. Contents of the bulk bag are released via the discharge chute so that the contents of the bulk bag flow into the silo loading hatch. For this embodiment, the dust seal prevents airborne dust associated with the flow from escaping into an exterior portion of the collapsible chute.

Provided in one embodiment of the present invention is an inhibitor removal system for sensor detection, comprising: a housing in which odorous gas flows in a pipe; a gas inlet part providing a passage through which the odorous gas flows into the housing; a pre-treatment part for removing odor detection inhibitors from the odorous gas flowing in the housing; a gas discharge part providing a passage through which the odorous gas is discharged from the housing; and a control unit for controlling the operation of a pre-treatment system in the pre-treatment part, wherein the pre-treatment part comprises a first pre-treatment part having a filtering device for filtering and separating out the odor detection inhibitors from the odorous gas; and/or a second pre-treatment part having an electrical dust collection device for collecting and separating out the odor detection inhibitors from the odorous gas.

An air filtration system includes a main body having a flow path; a first filter portion provided on the flow path and having a first body portion; a plurality of protrusions distributed and disposed on the first body portion; and a plurality of first through holes passing through the first body portion and interposed between the adjacent protrusions; wherein when an external fluid flows in the flow path, the external fluid passes through the protrusions first and then passes through each of the first through holes, so that the flowing external fluid is hindered by the protrusions, and thus a flow velocity at a position adjacent to the protrusions is lower than a flow velocity flowing through the first through holes, thereby vortices are respectively generated between orifices of the first through holes and the adjacent protrusions.

An air filtration system for a mobile unit having a vent fan and a kit for forming the air filtration system. The air filtration system includes a rigid outer cover made, a filter box, and a vent fan installed on a roof of the mobile unit. An air inlet passageway is formed in the rigid outer cover so that the vent fan may draw outside air through the filter box and into an interior space of the mobile unit. The air inlet passageway may include a louver for allowing air entry while protecting the filter box from rainwater. A base plate has a central opening that is positionable around a vent fan housing and securable to a vent fan flange to form a flat surface upon which to receive the filter box and the rigid outer cover.

An oil separator includes a container and a filter assembly. The filter assembly can include a casing, a valve guide, and a valve body. First and second chambers can be defined by a lower casing body. The valve guide can guide the valve body's movement between first and second positions in the first chamber or the second chamber. A first valve can be closed by a prong of the valve body in the first position such that unfiltered fluid enters an inlet of the oil separator, waste byproducts collect in a reservoir defined by the container, and filtered fluid is output from an outlet. The valve body can move from first to second positions with an accumulation of byproducts in the reservoir. In the second position unfiltered fluid may pass from the inlet to the outlet.

Listed are some of this invention's unique features for producing a healthier home and a safer clothes dryer vent within the same housing system, which may be installed within a typical wall system or as a free-standing unit in a laundry room.

Included are two airflow receiving ports that accepts airflow from a clothes dryer or optionally from a house's interior rooms and two airflow exhaust ports that discharge the same airflow into an exhaust pipe to the outside or optionally into the building interior as recycled airflow.

A drainage device removes water derived from condensate which forms in the exhaust pipe and otherwise flows back into the housing.

Two (2) receiving ports and the two (2) exiting ports combine to provide four (4) combinations of airflow management.

The choice of which of the four (4) airflow ports are activated for airflow passage is subject to a selection from a control system which contains switches for the desired airflow management thru the housing.

Additionally, an exhaust system constructed to select airflow destinations, first destination, airflow can be directed to exit to the building's outside atmosphere or second destination, airflow can be directed to exit into an interior duct system for recycling of the filtered airflow.

Additionally, the control system contains monitors and sensors to indicate unsafe temperatures, air pressure changes or filter blockage within the housing.

A shutdown mechanism within the control system stops the airflow exhaust fan and stops the clothes dryer to provide an additional measure of safety.

Included in the invention is a multi-filter filtration system that includes filters that block lint particulate from a clothes dryer and block indoor pollutants comprising pre-filters, True HEPA filters, with activated carbon filters and air cleaners to meet EPA Indoor Air Quality Standards and MERV Ratings.

A multi-speed airflow exhaust fan moves airflow in thru the receiving ports, thru the multi-filters and out thru the exiting ports. Additionally, within the housing, access openings with removable windows provide internal inspections and accessibility.

In conclusion the elements of this invention combine to improve the efficiency and safety of a clothes dryer's exhaust system and improve the indoor air quality of a home or commercial building.
