Problems solved by technology

However, due to the limited liquid-solid ratio of slurry-like materials for stirring and washing, the dispersion effect of solid particles is not ideal, and the slurry-like materials have to go through multiple beating-washing-filtering washing processes to meet the requirements.
Repeated washing of muddy materials not only results in large washing water consumption and low operating efficiency, but also leads to serious loss of solid materials and high pressure on environmental protection

Embodiment 1

[0036] A power wave washing device for muddy materials:

[0037] See attached figure 1 , 2, a muddy material dynamic wave washing device designed by the present invention is composed of mud feeder 1, mud atomizer 2, washing tank 3, washing water nozzle 4, gas-liquid separator 5, stirring device 6, liquid-solid separation 7, washing liquid circulation pump 8 and heat exchanger 9; the washing tank 3 is a cylindrical structure made of 1-30mm thick carbon steel or stainless steel or glass fiber reinforced plastic or plastic or a cylindrical structure with an enlarged upper end; The mud atomizer 2 is arranged in the center of the upper end in the washing tank 3, and the opening of the mud atomizer 2 is downward. After the mud ejected from the mud atomizer 2 meets the washing liquid ejected from the washing water nozzle 4, the A highly turbulent "foam zone" is formed in the washing tank 3, and the opening of the mud atomizer 2 is 50-2500 cm away from the top of the "foam zone"; O...

Embodiment 2

[0040] A plurality of mud-like material power wave washing devices are used in parallel to form a mud-like material power wave washing device, and the mud feed ports of a plurality of mud-like material power wave washing devices are connected in parallel with the total feed pipe, thereby The production scale of muddy material washing can be expanded.

Embodiment 3

[0042] A plurality of power wave washing devices for muddy materials are used in series to form a power wave washing device for muddy materials. The mud feeder 1 of the power wave washing device for muddy materials is connected, so that deep washing of muddy materials can be realized.

Abstract

A muddy material dynamic wave scrubbing apparatus and method are provided, the apparatus comprises a scrub tank, a gas-liquid separator and a liquid-solid separator, and a mud atomizer and a scrubbing water nozzle are arranged in a tank body of the scrub tank; the scrubbing method comprises: dispersing muddy material in a gaseous phase, enabling mud mists to contact scrubbing liquid jets and compressed air to form highly turbulent 'froth area' dynamic wave in the scrub tank such that solid particles contact gas and quickly renewed liquid to form gas-liquid-solid mixture, subjecting the gas-liquid-solid mixture sequentially to gas-liquid separation and solid-liquid separation such that efficient continuous scrubbing of the muddy material is finished. The apparatus is reasonable in structure, high in operating efficiency, good in scrubbing effect, simple to operate and applicable to large-scale industrial production for muddy material scrubbing in the metallurgical industry, chemical industry and other industries.

Description

technical field [0001] The invention relates to a dynamic wave washing device for muddy materials and a washing method thereof, belonging to the technical fields of metallurgy and chemical industry. Background technique [0002] In a broad sense, washing is the process of removing unwanted components from the object to be washed and achieving a certain purpose. The washing of muddy materials usually refers to the dissolution of soluble substances into the detergent through the action of some detergents (such as water, electrolyte solution, etc.), so as to reduce or eliminate the soluble substances entrained in solid particles. Soluble substances can be impurities It can also be valuable substances, but the ultimate goal of washing is to achieve the separation of solid particles and soluble substances. [0003] Slurry materials are usually formed in the production process of metallurgy and chemical industry. The sediment produced by solution reaction and the residue of liqui...
