Unpowered cyclone reaction method and reactor

Abstract

The invention relates to an unpowered cyclone reaction method and a reactor, wherein the method comprises the following steps of: (1) adding a flocculating agent into water containing suspended substances; (2) enabling the water with the flocculating agent to flow through a section of high-speed pipeline through an inlet pipeline, wherein the diameter of the high-speed pipeline is smaller than that of the inlet pipeline; (3) enabling the water flowing through the high-speed pipeline to flow through a section of middle-speed pipeline, wherein the diameter of the middle-speed pipeline is larger than that of the high-speed pipeline but smaller than that of the inlet pipeline; (4) enabling the water flowing through the middle-speed pipeline to flow through a section of low-speed pipeline, wherein the diameter of the low-speed pipeline is equal to that of the middle-speed pipeline; (5) enabling the water flowing through the low-speed pipeline to flow through a section of full-flow pipeline, wherein the diameter of the full-flow pipeline is much larger than that of the inlet pipeline; and (6) enabling the water flowing through the full-flow pipeline to flow through a section of outlet pipeline, wherein the diameter of the outlet pipeline larger than that of the inlet pipeline but smaller than that of the full-flow pipeline. The invention solves the technical problems of incapability of continuous working, large maintenance difficulty, low utilization ratio and high cost of traditional mechanical stirring and coagulation reaction and has the advantages of wide application range and continuous working.

Description

technical field [0001] The invention relates to a water treatment method and device. Background technique [0002] Existing coagulation reactions all use mechanical stirring. Generally, just after the medicament is added into the solution, the agitator stirs quickly, so that the medicament is quickly distributed into the water and the suspended solids in the water form very fine flocs, and then slowly stirred to make the small flocs The flocs collide with each other to form larger alum flowers for sedimentation or filtration. However, this stirring method still has the following defects: 1. The stirrer is composed of a motor, a reducer, a stirring paddle, etc., and requires regular maintenance; 2. The stirring process requires two speeds of fast stirring and slow stirring, and electrical control requires Frequency conversion control, or two sets of stirring mechanisms with different speeds; 3. The stirring process can only be batch stirring and cannot work continuously. C...
