Fluid bed regenerative thermal oxidizer and a method for its use

摘要

The present device is a fluid bed regenerative thermal oxidizer configured to minimize dead spaces within it and eliminate the need for complex valve systems, which are typically required to move treated and untreated air across fixed beds. The present device can be a fluid bed regenerative thermal oxidizer comprising a vertical stack having a combustion chamber near its interior center and desorber shelves located within the vertical stack above the combustion chamber and adsorber shelves located within the vertical stack below the combustion shelves. Ceramic spheres can be used as heat sinks that flow from the desorber shelves, around the combustion chamber and onto the adsorber shelves and then back to the desorber shelves. In this way heat from the combustion can be captured by the heat exchange material on the desorber shelves and released to preheat untreated air on the adsorber shelves.

主权项

1. A fluid bed regenerative thermal oxidizer, comprising:
a vertical reactor stack comprising a gas inlet at a lower end of the vertical reactor stack, a gas outlet located at an upper end of the vertical reactor stack and a combustion chamber located within the vertical reactor stack between the gas inlet and the gas outlet wherein the combustion chamber also comprises a fuel burner; heat exchange material; two or more adsorber shelves located within the vertical reactor stack and below the combustion chamber configured to allow air to flow through each adsorber shelf and also configured to contain the heat exchange material and allow the heat exchange material to move across each adsorber shelf and exit one end of each adsorber shelf, wherein the two or more adsorber shelves are configured such that the heat exchange material remains within the vertical reactor stack when moving from at least one adsorber shelf onto another adsorber shelf; and two or more desorber shelves located within the vertical reactor stack and above the combustion chamber configured to allow air to flow through each desorber shelf and also configured to contain the heat exchange material and allow the heat exchange material to move across a desorber shelf and exit one end of the desorber shelf and onto one or more desorber shelf, wherein the two or more desorber shelves are configured such that the heat exchange material remains within the vertical reactor stack when moving from at least one desorber shelf onto another desorber shelf.
