Multistage integrated hydrodynamic cyclone separator

[0005] The purpose of the present invention is to provide a practical multi-stage integrated hydrodynamic cyclone separator with optimized treat...

Described conical deflector 10 is inclined downwards to its center from its outside, makes the space of the one-stage cone segment separation chamber 2 of conical deflector 10 inner side be big and small, become a conical space, This can not only improve the swirling effect and stability, but also guide the rainwater runoff that flows into the cylindrical deflector 9 and spirals downward to the secondary column separation chamber 3. At the same time, this configuration design, in the While improving the swirl effect, the separation space of the secondary column separation chamber 3 and the tertiary column separation chamber 4 is increased. In addition, the floating matter separated in the rainwater stays on the top of the first-level cone section separation chamber 2, that is, the inside of the columnar deflector 9 and the floating matter storage chamber 1, which can prevent the floating matter from affecting the conical deflector. Swirl effects within 10 are affected. In addition, the bottom of the conical deflector 10 is designed so that the floating matter and fine particles in the rainwater runoff moving downward spirally form an upward backflow, which is in the lower part of the first cone segment separation chamber 2, that is, in the conical Inside the deflector 10, the fine particles and floating objects form a backflow when approaching the outlet of the first-stage cone section separation chamber 1, and finally stagnate near the center of the swirling fluid, thereby realizing the retention of fine particles and floating objects.

Described helical deflector 11 is arranged on the below of the tangential interface of tangential water inlet pipe 7 and cylindrical deflector 9, is connected with the inwall of conical deflector 10, can restrict fluid trajectory, improve vortex flow type, reduce flow field disturbance, and guide the stable flow of fluid, so the stability of fluid rotation at high flow rate is improved.

Described inclined baffle 12 is positioned at the top of the bottom outlet of described conical deflector 10, can prevent the generation of short-flow phenomenon, and inclined baffle 12 is inclined downwards from its outside to its center, and is arranged at the bottom There is a skirt 12.1, which can control the outflow of the liquid in the secondary column se...
