Carbon dioxide flue gas collector

The utility model relates to a carbon dioxide flue gas collector which comprises a reaction box, a flue gas treatment mechanism is arranged in the reaction box, the flue gas treatment mechanism comprises a flue gas gathering block fixedly connected with the inner bottom wall of the reaction box, and a flue gas inlet pipe extending into the flue gas gathering block is fixedly connected into the reaction box. And the interior of the smoke gathering block is fixedly connected with a flow dispersing plate, the right side of the reaction box is fixedly connected with a motor, and the output end of the motor is fixedly connected with a rotating shaft. According to the carbon dioxide flue gas collector, the retention time of flue gas in the reaction box can be prolonged, and the flue gas circularly flows between the flue gas blocking block and the flue gas gathering block along with rotation of the rotational flow blades according to a preset route, so that the spraying head sprays an absorbent towards a flue gas fl
