The utility model relates to the technical field of chemical waste gas treatment, and discloses a safe treatment device for filtering chemical waste gas. In the application, the treatment tower is used as a main part for treatment, and gas enters the treatment tower from the gas inlet pipe, and is finally discharged outwards through the gas outlet pipe after being treated. A spraying agent for treating the waste gas is sprayed outwards through a flow control pipe, a spraying pipe and a spraying head, and after spraying, a downward treatment reagent is in contact with the upward air to be used for realizing treatment. And then a flow control assembly formed by a bearing vertical plate, a driving rod, an inserting plate, a limiting plate, a limiting hole and a limiting bolt is used for controlling the spraying speed of the reagent, so that the contact time between the reagent and gas can be controlled, full contact is achieved, and the gas treatment amount in the whole process is large and efficient.
