Description
Technical Field
The utility model relates to a reactor, in particular to a vertical flocculation reactor.
Background
Flocculation is a unit process in water, wastewater and other industries that allows smaller particles to aggregate into flocs for subsequent removal steps. To assist the growth of the flocculent, a certain residence time must be provided under defined turbulent conditions to ensure that no settling occurs during flocculation. The prior art generally uses a reaction tank with a low-speed stirrer, but this method has the disadvantage of low hydraulic efficiency. Another popular method is to use a tubular reactor. In a tubular reactor, liquid flows at a velocity through a series of horizontal flow-through channels under conditions of low turbulence. However, such tubular reactors are typically constructed with a series of horizontal tubular segments connected by 180 degree bends. A disadvantage of horizontally mounted pipe sections is that the floor space is relatively large.
In addition, a common problem with horizontally mounted pipe sections is that when the flow rate temporarily drops or heavier particles are formed due to changes in chemical conditions, they can cause the particles to settle. Once the particles settle to the bottom of the flow-through channel, higher energy in the form of high flow velocity is required to re-agitate the particles. This tends to result in the build-up of sediment and can seriously impair the flocculation process. Another common problem is the accumulation of air bubbles at the bottom of the flow channels. A large volume of liquid is saturated or supersaturated with gas, and excess gas can form bubbles. Since the surface of many plastic flow channels is hydrophobic, bubbles often stick to the surface and grow slowly until larger bubbles are released. These larger bubbles will generate higher mixing energy, again destroying the flocs.
To avoid the above problems, the reactor tube sections may be installed vertically. Short interruptions of the water flow do not lead to the build-up of sediment. However, the use of standardized plastic parts results in complex designs, expensive support structures and large distances between the reactor flow channels, large system footprints; and drainage and venting are complicated.
