[0014] Embodiment 1

[0015] As Figures 1 to 3As shown in the figure, the utility model discloses an RTO waste gas incinerator, which includes a base 1, a furnace body 2, a furnace cover 3, heat preservation cotton 4, an intake pipe I 5, an air pipe assembly 6, a branch pipe 7, an intake pipe II 8, ceramic regenerators 9, a support base 10, supports 11, fastening screws 12, and connecting pipes 13. The upper surface of the base 1 is provided with the furnace body 2. The cross-section of the furnace body 2 is an equilateral heptagon. The furnace cover 3 is installed on the top of the furnace body 2. There are two circles of the heat preservation cotton 4, which are installed on the outer wall of the lower side of the furnace body 2. The intake pipe I 5 is installed on the outer wall of the front side of the furnace body 2, and an ignition device is installed on the part of the intake pipe I 5 located inside the furnace body 2. The air pipe assembly 6 is installed in the center of the upper surface of the base 1 inside the furnace body 2. Three intake pipes II 8 are arranged around its circumference, and seven groups of branch pipes 7 are provided on the upper surface. The branch pipes 7 are equipped with electric control switches.
