The main raw materials for the preparation of monobasic peracetic acid are glacial acetic acid, hydrogen peroxide, and concentrated sulfuric acid. The concentration of hydrogen peroxide is 30%-40%; the concentration of glacial acetic acid is 96%-99%; the concentration of concentrated sulfuric acid is 98%; one or more stabilizers are selected: hydroxyethylidene diphosphonic acid, 8-hydroxyquinoline, polyethylene glycol, citric acid, phosphoric acid, and the addition amount is 0.5%-2.5%; S2. First, one of the main raw materials is introduced into the mixing barrel (7). Four batching boxes (13) are provided, which are used to store other main raw materials and stabilizers respectively. Each batching box (13) is equipped with an oil cylinder (2004). The oil cylinder (2004), the second connecting pipe (2002) and the tooth plate (2008) can be disassembled and replaced as a whole. Different batching boxes (13) are equipped with oil cylinders (2004) with different inner diameters.
