Abstract
A woodchip based bio-filtration system for odor and particulate matter removal from exhaust fan emissions from confined animal feeding operation buildings where visual inspection of the initial point of contact between the airflow from the building and the organic media can be made, and where the initial point of contact is directly sprayed with nozzles and/or stirred or agitated manually or mechanically to disperse matter (feathers, dust, fecal matter, etc.) which might tend to restrict airflow through the media.
Claims20
A wood chip based bio-filtration system for removing matter and pollutants from an airflow exiting a confined animal feeding operation building;
- the system comprising:
- a layer of organic media with microorganisms attached thereto, disposed in said airflow for removing odor from air passing therethrough;
- said layer of organic media with microorganisms attached thereto having an initial point of contact where said air flow first encounters a portion of said layer of organic media with microorganisms attached thereto;
- said initial point of contact being located so as to allow access by a human being, at least partially located within said airflow, to facilitate direct visual inspection of said initial point of contact;
- and
- said layer of organic media with microorganisms attached thereto comprises at least one of wood chips, tree bark, peat, and straw.
A bio-filtration system for removing matter and pollutants from an airflow which has been exhausted from a confined animal feeding operation building;
- the system comprising:
- an enclosure confining and channeling a portion of said airflow;
- a layer of organic media with microorganisms attached thereto, disposed in said airflow for removing odor from air passing therethrough;
- said layer of organic media with microorganisms attached thereto forming a portion of said enclosure through which said airflow is permitted to exit the enclosure;
- said layer of organic media with microorganisms attached thereto having an initial point of contact where said air flow first encounters a portion of said layer of organic media with microorganisms attached thereto;
- said enclosure being configured and said initial point of contact being located within said enclosure so as to allow a human being to perform a visual inspection said initial point of contact.
A bio-filtration system for removing matter and pollutants from an airflow which has been exhausted from a confined bird feeding operation building;
- the system comprising:
- a semi-cylindrical enclosure disposed adjacent to an exhaust fan of said confined bird feeding operation building, said enclosure confining a portion of said airflow;
- said semi cylindrical enclosure extending orthogonally from said confined bird feeding operation building comprising:
- a transparent polycarbonate roof panel over a skeletal frame;
- a stainless steel containment tray configured for holding porous organic media;
- a support structure to elevate said stainless steel containment tray above the surface of the earth;
- an end panel, disposed opposite of the exhaust fan;
- a layer of organic media with microorganisms attached thereto, disposed in said stainless steel containment tray and in said airflow for removing odor from air passing therethrough;
- said layer of organic media with microorganisms attached thereto forming a portion of said enclosure through which said airflow is permitted to exit the enclosure;
- said layer of organic media with microorganisms attached thereto having an initial point of contact where said air flow first encounters a portion of said layer of organic media with microorganisms attached thereto;
- said initial point of contact being substantially planar and parallel to the surface of the earth and on a topside of the layer of organic media;
- said transparent polycarbonate roof panel being configured so as to allow a human being to perform a visual inspection of said initial point of contact from outside said enclosure;
- said access door to allow a human being to physically enter the enclosure to mix the organic media at the initial point of contact;
- a pressure sensor disposed in and configured for measuring air pressure within said enclosure;
- said pressure sensor for providing for an actuating signal;
- an automated stirring rake which is sized, configured and located so as when actuated by said actuating signal, to disperse matter accumulating at said initial point of contact which may impeded airflow through said layer of organic media and thereby increase air pressure within said enclosure;
- the automated stirring rake may be configured to continue to operate until the pressure sensor determines that the air pressure within the enclosure has dropped below a termination threshold;
- and
- a hydration system of spray nozzles disposed above the initial point of contact and spraying water thereon for maintaining a moist environment for microbial growth.
