The size of the upper part of the reactor becomes larger, which makes the liquid flow rate slower, which is conducive to the precipitation of particles that have not settled in the three-phase separation mechanism under the action of the transition zone and the sedimentation plate, and prevents the loss of iron-carbon materials in the reactor body from the overflow weir .

Further, both the bottom of the reactor body and the bottom of the gas chamber are provided with vents. The venting operation can be performed when there is agglomeration or serious blockage in the reactor body or the gas chamber by using the venting port.

Beneficial effects: In this application, a double stirring mechanism is set between the air inlet mechanism and the water inlet mechanism. Under the action of the two stirring paddles, the bottom material is stirred toward the upper part, and the upper material is stirred toward the lower part, which not only makes the stirring even, but also can make the hole The iron carbon and flocs on the upper part of the plate are stirred upward to avoid the problem of clogging caused by accumulation above the orifice plate; the air inlet mechanism and the water inlet mechanism can also achieve the stirring effect at the same time. This application has multiple stirring, which can effectively avoid the formation of iron carbon blocks to avoid clogging.
