Process Overview Video Description
The following is a video description for the 6 minute video displaying ARI Technologies Inc Thermochemical Conversion Process Overview. Each bolded headlines below correlates with the same headlines that can be observed in the video. The text accompanying each bolded headline provides a concise description of what the video demonstrates when the viewer sees each headline in the video.
- Waste Feed Operations: Timed buzzer alerts the worker to push bags of asbestos waste off of a scale and onto a conveyor. Each bag weighs approximately 50 LB and is loaded onto the conveyor every 3.5 minutes. This adds up to a total daily load of 10/tons per day.
- Asbestos Bag Feed & Shredding: The bag is moving up the conveyor across to the conveyor scale where the bag’s weight is electronically recorded prior to being dropped into a shredding system. Shredder housing is held at slight negative pressure and vented through ductwork to HEPA filters in order to avoid the risk of releasing harmful emissions into the workplace. The shredded waste is fluxed, mixed, and conveyed to a feed hopper. One cannot see the flux, mix, or conveyance process since they are all enclosed and out of sight.
- Ram Feeder Pushes Waste into Hearth: The prepared waste hopper can be observed in the background. As the ram extracts, the prepared waste descends from the hopper in the anterior of the ram where it is then pushed into the furnace. Cycle of ram is timed for 10 tons/day.
- First Cake Breaker Breaks up Waste: The rotating shaft is armed with blades to The rotating shaft is equipped with blades to separate the compressed pile of waste just pushed onto the hearth by the ram feeder. It is not possible to view this process because the pile of waste that moves into view from the right conceals this process. The additional cake breaker can be observed in the background rotating in the alternate direction.
- Second Cake Breaker Spreads Waste: The second cake breaker can be seen exposing cooler waste and dispersing it to an even depth on the hearth to increase heat transfer rates, and to achieve uniform heating.
- Removal Plow Collects and Rake Removes Treated Product: the alloy plow gathers treated product on the hearth. The rake intermittently drags the product of the hearth where it is released into a water quench. At this time , the waste The alloy plow gathers treated product on the hearth. The rake intermittently drags the product off of the hearth where it drops into a water quench. At this point, the waste discharge is approximately one-half to- two thirds the mass of feed and one-half to one-tenth the volume of the feed.
- Removal of Treated Product Bins: Treated product is sent from the Treated product is directed from the water quench tank through the auger conveyors to enclosed storage bins where it awaits a confirmation analysis. Each bin has a capacity of approximately 2 tons of product which equals to approximately 4-tons of asbestos fee
- Removal of Treated Product Following Analytical Clearance: Upon being declared as “asbestos-free”, the trap door on the holding bin is opened and the treated product is position on a roll-off bin where it will await transportation off site.
