High-efficiency environmentally-friendly catalyst adding device for preventing local alkaline saponification

The invention relates to the technical field of environmental-protection treatment equipment and discloses a high-efficiency environmentally-friendly catalyst adding device for preventing local alkaline saponification. The device of the invention comprises a seal box and a material guiding pipe body inside the seal box, and also comprises an amount control block and a blanking box positioned inside the seal box. A suction mechanism is fixedly connected on the sidewall of the inner cavity of the seal box. The suction mechanism is composed of a fixed plate, an electromagnet and a first iron plate. The side surface of the fixed plate is fixedly connected with the sidewall of the inner cavity of the seal box. According to the high-efficiency environmentally-friendly catalyst adding device forpreventing local alkaline saponification, catalyst granules pass through the material guiding pipe body and successively pass through six first conduits, six feed chutes on the amount control block, six blanking pipes, six fe
