Rapid decarbonization and coagulation integrated clarifying equipment

Abstract

The invention provides rapid decarbonization and coagulation integrated clarifying equipment, which comprises a mixed reaction chamber, an internal reflux circulating reaction chamber, an external reflux circulating reaction chamber and a settling zone which are sequentially sheathed together. A reflux port which is communicated with the internal reflux circulating reaction chamber is arranged on the internal wall of the mixed reaction chamber. A closed small-resistance water distribution ring is arranged at the top of the internal reflux circulating reaction chamber. A water outlet hole which is communicated with the internal reflux circulating reaction chamber is arranged in a ring plate at the bottom of the water distribution ring. An internal reflux circulating turbulent flow mixing device is arranged in the internal reflux circulating reaction chamber. An external reflux circulating turbulent flow mixing device is arranged in the external reflux circulating reaction chamber. Since internal and external multistage reflux circulating reaction chambers are arranged, the rapid decarbonization and coagulation integrated clarifying equipment provided by the invention has the advantages that the multistage solid-liquid separation of sludge is realized, the reaction process flow is lengthened, the reflux ratio is increased, the upflow velocity of a separation zone is obviously improved, the output of the equipment is large, the occupied area is small, the investment cost is low and the safe and reliable operation of the equipment is guaranteed at the same time.

Description

technical field [0001] The invention relates to a water treatment equipment, in particular to a clarification and sedimentation equipment, which is especially suitable for lime advanced treatment of urban reclaimed water, water supply treatment, drainage treatment, circulating water treatment, seawater desalination and large-scale water quality clarification and sedimentation treatment in industrial sectors. Background technique [0002] figure 2 It is an existing mechanical stirring acceleration clarification equipment used in lime softening treatment, which includes: a first reaction chamber 21, a second reaction chamber 22, a separation area 23, a mud storage bucket 24, an agitator 25, and a mud scraper 26. When the equipment is working, the water enters the reaction chamber under the action of the pump, rises after being stirred by the agitator, flows out from the top of the first reaction chamber to the second reaction chamber, and then partly flows back into the first ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of the existing mechanical agitation and clarification equipment for lime softening treatment, such as short reaction process and low ascending flow rate in the separation zone, resulting in small equipment output and large floor area, a new type of rapid decarbonization coagulation integrated clarification is proposed. equipment, and adopt the following technical solutions to realize:
