The instant disclosure described a system and method to prevent the oxidizer overheating using cold side bypass for a VOCs treatment system with series rotor, which may be used in an organic waste air treatment system. The system is equipped with a Thermal Oxidizer (TO), a First Heat Exchanger, a Second Heat Exchanger, a third heat exchanger, a First Cold-Side Transporting Pipeline, a First Adsorption Rotor, a Second Adsorption Rotor, and a Chimney. There is a Cold-Side Proportional Damper installed between the First Desorption-Treated Air Pipeline and the First Cold-Side Transporting Pipeline, or it is installed on the First Desorption-Treated Air Pipeline. When the VOCs concentration becomes higher, the Cold-Side Proportional Damper can regulate the airflow to adjust the heat-recovery amount or concentration, when treating the organic waste air, it can prevent the TO from being overheated due to high oxidizer temperature, and protect it from Thermal Oxidizer shut-down.

In order to provide a method for the purification of a raw gas stream containing water vapour that is simple and cost-efficient to perform, it is proposed that the method should comprise the following: feeding the raw gas stream to a reforming region in which contaminants in the raw gas stream react chemically with the water vapour in the raw gas stream, as a result of which a reformed raw gas stream is obtained; feeding the reformed raw gas stream and an oxidising agent stream to an oxidation region in which constituent parts of the reformed raw gas stream react chemically with oxidising agent of the oxidising agent stream, as a result of which a clean gas stream is obtained. Moreover, optionally a closed-loop control of the oxygen content is provided. Further, it is optionally provided for the clean gas stream to be fed to a condenser, as a result of which the volumetric flow of the clean gas stream is reduced and/or as a result of which energy can be recovered and used for pre-heating the oxidising agent and for other production processes.

A regenerative thermal oxidizer assembly includes a first housing member and a second housing member. The first housing member defines a regenerative portion and a combustion chamber. The second housing member defines an inlet chamber and an outlet chamber. A regenerator is disposed within the regenerative portion of the first housing member and defines a central axial opening extending to the combustion chamber. A thermal element extends through the axial opening to the combustion chamber for providing heat to the combustion chamber for initiating combustion inside the combustion chamber. The first housing member is rotatable around an axis defined by the axial opening relative to the second housing member for rotating the regenerator relative to the inlet chamber and the outlet chamber.

Methods and systems for oxidizing gas are provided. An example regenerative oxidizer is provided that includes a combustion chamber to heat gas present in the combustion chamber. The regenerative oxidizer also includes a first heat exchange media bed and a second heat exchange media bed, each in fluid communication with the combustion chamber. The regenerative oxidizer also includes a rotary valve disposed at least partially between the first heat exchange media bed and the second heat exchange media bed. The rotary valve may alternate the flow of gas between a first and a second airflow direction. The first heat exchange media bed, the rotary valve, and the second heat exchange media bed are arranged with respect to each other such that the gas pathway between the first heat exchange media bed and the rotary valve and between the second heat exchange media bed and the rotary valve is non-linear.
