Description

Technical Field

[0001] This utility model relates to the field of aluminum profile straightening, specifically a safe and efficient organic waste gas regenerative combustion device. Background Technology

[0002] Regenerative Thermal Oxidizers (RTOs) are used to purify organic waste gases through combustion. Also known as regenerative thermal incinerators, RTOs are highly efficient equipment for treating organic waste gases. Compared to traditional catalytic combustion and direct-fired thermal oxidizers (TOs), RTOs offer advantages such as high thermal efficiency (≥95%), low operating costs, and the ability to handle large volumes of low-concentration waste gas. For slightly higher concentrations, secondary waste heat recovery is also possible, significantly reducing production and operating costs. The basic principle is to burn VOCs in a high-temperature, low-oxygen-concentration (by volume) atmosphere.

[0003] For example, the authorized patent with publication number CN221923521U (Integrated Waste Gas Regenerative Combustion Unit) includes an installation box, a partition, a combustion box, multiple heat exchange tubes, and a burner. The installation box has an air inlet and an exhaust outlet. The partition is fixedly installed inside the installation box. The combustion box is fixedly installed on the installation box, and an opening is provided on the side of the combustion box away from the partition. The two ends of the heat exchange tubes are respectively fixed through the partition and the combustion box. The burner is fixedly installed on the installation box and passes through the opening. This invention, by setting heat exchange tubes between the combustion box and the partition, and providing an opening on the side of the combustion box away from the partition, allows the waste gas to sequentially pass through the gaps between multiple heat exchange tubes and the gap between the combustion box and the installation box for catalytic reaction and temperature increase, without relying entirely on the heat exchange tubes, thus optimizing the structural layout within the installation box.
