Description

Assembled high-density precipitation reactor

Technical Field

The utility model relates to the field of sewage treatment, in particular to an assembled high-density precipitation reactor.

Background

The coagulating sedimentation tank is taken as a mature water treatment process unit and is generally used in a sewage treatment plant, and compared with the traditional flocculating sedimentation tank, the high-density sedimentation tank has the advantages of saving occupied space and treating effect, and is widely applied to pretreatment or advanced treatment systems of the sewage treatment plant.

When coagulant, flocculant and high-density medium are added in the existing high-density sedimentation tank, the coagulant, flocculant and high-density medium are generally added step by step, the reaction is separated, the set reaction areas are more, and the flow is longer.

Disclosure of Invention

The utility model provides an assembled high-density precipitation reactor, which can add and mix new sewage and medicament in a reaction zone, and separate and couple the high-density flocculation reaction zone and precipitation into a whole through rotation of a lifting stirrer and self-sliding reflux of an inclined plate arranged in a guide cylinder.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an assembled high-density precipitation reactor comprises an outer cylinder, an inner cylinder, a stirrer, a guide cylinder, a slip inclined plate, an inclined tube precipitation area, an effluent weir, slip slits, a mud discharge pipe, a water inlet pipe and a variable frequency motor;

the lower part of the outer cylinder is provided with a mud sliding plate, the mud sliding plate penetrates through the inner cylinder, the lower end of the mud sliding plate is positioned at the bottom of the inner cylinder, the upper end of the mud sliding plate is positioned on the outer cylinder, a pipe chute sedimentation area is arranged at the middle upper part between the outer cylinder and the inner cylinder, and a water outlet weir is arranged above the pipe chute sedimentation area;

the inner cylinder is internally provided with a guide cylinder, the middle of the guide cylinder is provided with a stirrer, the stirrer is connected with a variable frequency motor through a central shaft, a water inlet pipe is arranged below the guide cylinder, and the lower part of the inner cylinder is provided with a slip joint and a mud discharge pipe.

Preferably, the stirrer is a lifting stirrer.

Due to the structure, the utility model has the beneficial effects that:

1. the mixed liquid in the reactor forms high-density large-particle precipitated flocs through longitudinal circulation and anisotropic flocculation, and can flocculate micro suspended matters and colloid substances in sewage into larger particles which are easy to settle, thereby facilitating settlement;

2. the stirrer has the function of lifting sewage, can fully mix with the medicament while lifting the sewage, and performs high-density flocculation with the mixed liquid which flows back, so that the flocculation effect is enhanced;

3. when the flocs in the mixed liquid descend outside the guide cylinder to the sliding mud seam, a part of sludge automatically slides to the mud discharge hopper under the action of the sliding mud sloping plate, and a part of sludge flows back into the guide cylinder to complete the coagulation process together with the newly-fed sewage and the medicament, so that no extra power equipment is provided.
