This invention belongs to the field of waste gas treatment technology, and in particular, it is a constant temperature waste gas treatment device suitable for integrated spray painting and baking booths. The device includes a spray painting and baking booth main body, with an air duct at the bottom. A flue gas treatment component and a heat pump blower are located on one side of the air duct, and the air duct is connected to the flue gas treatment component. This invention adopts a "one-in-one-out" design. When adsorption filter plate one / adsorption filter plate two approaches saturation due to adsorption of highly viscous substances, the device immediately switches to adsorption filter plate two / adsorption filter plate one for operation. Simultaneously, the high-temperature waste gas generated during the baking process (with auxiliary heating) is used to perform in-situ high-temperature desorption of the saturated adsorption filter plate one / adsorption filter plate two, achieving in-situ regeneration of activated carbon. This significantly extends the service life of the activated carbon and avoids the high consumable costs and labor maintenance costs associated with frequent replacements.
