The specific operating principle is that when water passes through the water inlet pipe of the cyclone decontaminator, it first forms a surrounding fluid that is obliquely downward along the tangent direction of the cylinder. The water flow rotates and moves downward. When the water flow reaches the cone, it turns to rotate upward along the axis of the cylinder and is finally discharged through the top water pipe. Under the action of the fluid inertia centrifugal force and its own gravity, the impurities fall into the conical slag bucket at the bottom of the equipment along the cone wall;
