Removing particulates
First Claim
1. A method comprising providing a solid waste treatment system, further comprising providing an autoclave having a steam outlet, a particulate filter, removing particulates suspended in steam discharged from the steam outlet of the autoclave following processing of solid waste, the method comprising the steps of:
- discharging steam from the autoclave via the steam outlet;
routing the discharged steam to an inlet of a separation vessel that further includes an outlet and a baffle between said inlet and said outlet, whereby the baffle is so configured so that steam is incident upon the baffle to reduce its flow velocity, and therein the particulate filter is provided after the outlet of the separation vessel to catch particulates in the steam exiting the separation vessel;
charging the autoclave with steam routed from a steam storage system via the steam outlet and then the inlet of the separation vessel, thereby forcing particulates caught in the filter to be removed therefrom and to drop to a bottom of the separation vessel; and
collecting particulates that drop from suspension in the steam and from said filter at the bottom of the separation vessel.

Abstract
In a solid waste treatment system comprising an autoclave (201) not having a particulate filter at its outlet, a method of removing particulates suspended in steam discharged from the autoclave following processing of solid waste is disclosed. The method includes discharging steam from the autoclave; routing the steam to the inlet (301) of a separation vessel (209) that further includes an outlet (303) and a baffle (302) between the inlet and the outlet; and collecting particulates (304) that drop from suspension in the steam at the bottom of the separation vessel. The baffle is configured so that steam is incident upon the baffle to reduce its flow velocity.

9. A system comprising:
-
a solid waste treatment system, further comprising; an autoclave having a steam outlet without a particulate filter; a separation vessel having an inlet, an outlet, and a baffle between the inlet and the outlet; piping between said steam outlet of said autoclave and the inlet of said separation vessel; a steam storage system connected to the outlet of the separation vessel; and a filter after the outlet of the separation vessel; wherein; steam exhausted from said autoclave is routed from said steam outlet of said autoclave through said piping, and through said separation vessel via the inlet and then the outlet; the baffle is configured so that said steam exhausted from said autoclave is incident upon the baffle to reduce the flow velocity thereof, thereby causing particulates to drop from suspension in the steam and collect at a bottom of the separation vessel, whereafter any remaining particulates are caught in said filter; and steam from said steam storage system to charge said autoclave is routed through the separation vessel via the filter and outlet and then the inlet, and through said piping to said steam outlet, whereby particulates caught in the filter are removed therefrom and drop to the bottom of the separation vessel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
