Problems solved by technology

The drying process also consumes so much energy that it is not economically viable
[0004] In addition to aluminum hydroxide, wastewater slag also contains a large amount of impurities, which limits its recycling value and limited application range

Embodiment Construction

[0029] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0030] The invention provides a treatment method for aluminum waste water slag, the process flow chart is as follows figure 1 shown, including:

[0031] Preliminary drying step: preliminarily drying the waste water residue to a water content of 5-30%;

[0032] In this step, conventional methods can be used to rapidly dry the waste water slag. The drying methods include but are not limited to sun drying, hot air drying or rotary kiln drying. The most appropriate way; preferably, drying to a moisture content of 25-30%;

[0033] Stacking steps: Stack and mature the preliminarily dried waste water residue for 6-24 hours;

[0034] In this step, by stack...

Abstract

The invention discloses a method for treating aluminum waste water slag. The method comprises the sequential steps of preliminary drying, stacking, pulverization, microwave drying, high-speed dispersion and collection. Meanwhile, the invention provides a treatment device implementing the method. The device comprises a stacking box, a pulverizer, a conveying belt, a microwave box, a high-speed disperser, a cyclone separator, a material collection box and dust collectors. Products obtained after treatment conducted through the method or device comprise a powder material and ultrafine powder. The powder material and the ultrafine powder can be applied to production preparation of heat-preservation materials. The method is low in energy consumption; and under the circumstances that energy consumption is low, the raw material requirement is low and emission is low, the aluminum waste water slag can be dried and pulverized into the powder material step by step, wherein the powder material is good in orderliness and light in character.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment, in particular to a treatment method for aluminum waste water slag, a device, a product and an application thereof. Background technique [0002] At present, the aluminum industry produces waste water in the production process, and the waste water will form a large amount of waste water slag after alkali precipitation. Because this kind of waste water slag contains a large amount of aluminum ions, it is very harmful to the human body, so the country defines it as hazardous waste. [0003] At present, the commonly used treatment method for aluminum oxidation wastewater slag is landfill. But there are also many companies that will secretly discharge the factory, which will greatly pollute the environment. The difficulty in the treatment of waste water slag lies in its high water content, and it needs to be dried to recycle it. The drying process also consumes so much energy tha...
