Motionless Mixer - Sludge (Hi-Pass)

Descripción General

The "Hi-Pass" Flash Mixer design effectively mixes polymer solution into sludge flows prior to dewatering processes. The unique design is not dependent on any "standing" or "trailing vortex" flow phenomena, is especially resistant to fouling or clogging, and has a very low pressure drop. Polymer savings in excess of 25% can be achieved along with dryer cake solids in dewatering operations.

Especificación Detallada

The KOMAX "Hi-Pass" Flash Mixer is designed to effectively mix polymer solution into sludge flows prior to dewatering process. Polymer savings in excess of 25% can be achieved. Features of this unit include:

1: MIXING ACTION: Each mixing element set in combination sweeps approximately two thirds of the circumference of the pipe and directs the flow to the opposite side, providing very strong "wall-to-wall" radial transfer. The standard four element set includes three inter-set cavities where intensive contacting occurs due to strong momentum reversal and flow impingement.
Performance is not dependent on any "standing" or "trailing vortex" flow phenomena, hence it is very insensitive to variations or perturbations in the incoming flow, and all required mixing takes place within the mixer's length. No downstream "clear" or "free" flow lengths are required to complete the mixing.

2: NON-FOULING DESIGN: This mixer is designed to be extremely resistant to fouling or clogging. The edges of the element sets are smoothly contoured with a large radius. The intersections of element ends with the wall are all oblique angles, eliminating "corners" that can trap solid or fibrous materials and began material accumulation. Momentum reversal and flow impingement provide a "self-cleaning" environment. The "Hi-Pass" design will readily pass individual solid items with a nominal diameter up to 1/4 that of the mixer.

3: ENGINEERED INJECTOR: The injector manifold is designed to present the diluted polymer solution to the sludge flow for optimum efficiency. Better dispersion of the small amount of solution through the mixing elements is achieved.

The Komax "Hi-Pass" Flash Mixer will reduce polymer consumption and costs and will produce dryer cake solids in dewatering operations. It is particularly suited for use on the feed line to devices such as belt fiber presses, plate filter presses, gravity belt thickeners, centrifuges, and pressure or vacuum filters.
