The invention provides a chlorinated polyethylene continuous reaction method and system with a solution method, and belongs to the field of chlorinated polyethylene preparation. The method comprises the following specific steps: preparing a suspension solution by adding desired raw materials into an emulsifying kettle of a hydrochloric acid solution; continuously feeding the suspension solution into a low temperature reactor, an intermediate temperature reactor and a constant temperature reactor in sequence; continuously feeding materials after a reaction in the constant temperature reactor into a desuperheater and a continuous separator to separate the chlorinated polyethylene in the solid phase from hydrochloric acid in the liquid phase; feeding the chlorinated polyethylene in the solidphase into a continuous boiling drying bed, feeding into a first section, a second section, a third section and a fourth section of the drying bed in sequence, and cooling to obtain a chlorinated polyethylene product; packagi
