Embodiment 1

[0045] The method for treating waste emulsion sludge in this embodiment includes the following steps:

[0046] 1. Ingredients, quantitatively proportion the waste emulsion sludge and fly ash and proceed to the next step;

[0047] 2. Mixing, mixing the materials prepared in the batching step, and making them into powdered granules through repeated rolling, stirring and mixing operations;

[0048] 3. Discharge and output the final product of the mixing step.

[0049] Existing waste emulsion treatment usually adopts chemical treatment methods. After demulsification, flocculation, air flotation, water treatment and other processes, the waste emulsion is finally treated and discharged. This treatment method first requires special equipment. A series of chemical reactions are carried out in the equipment. It is difficult for the treated products and accompanying organisms to meet the emission standards, which increases the burden on the environment. After testing and analysis, the calorific...

Embodiment 2

[0090] The waste emulsion sludge treatment method of this embodiment is further improved on the basis of Example 1. Before the batching step, the material selection step is carried out. The water content of the mixed fly ash is ≤ 1%, and the waste The water content of the emulsion sludge is ≤50%.

[0091] The product obtained by this method must be combustible and its combustion effect must be guaranteed. The water content of the final product must be very low. Therefore, the raw materials (waste emulsion sludge) and additives (fly ash) need to be selected when compounding. Select materials that meet the above water content standards for batching. When the water content of fly ash is greater than 1%, the product obtained by mixing is easy to agglomerate, which is not conducive to combustion and cannot well neutralize and absorb the water in the waste emulsion sludge. , The water content of the waste emulsion sludge is greater than 50%. In order to absorb the water during the mixi...

Embodiment 3

[0093] The waste emulsion sludge treatment method of this embodiment is further improved on the basis of embodiment 2. Before the batching step, the material selection step is carried out. The content of particles with a particle size of ≤ 1 mm in the blended fly ash is ≥ 90%.

[0094] In actual operation, it is found that the particle size of fly ash affects the mixing effect of the materials during the mixing process, thereby affecting the combustion effect of the mixed product. When the content of particles with a particle size ≥ 1mm in the fly ash is greater than 10% , There are more solid slag and agglomerated materials in the mixed product. This material cannot be burned sufficiently during combustion, and it will affect the forward flow of the fuel conveying equipment during combustion. Therefore, before the batching, the pulverized coal The ash is selected first, so that the content of particles with a particle size of ≤1mm in the mixed fly ash is ≥90% to ensure the mixin...

Abstract

The invention discloses a waste emulsion sludge treatment method, and belongs to the field of industrial waste treatment methods. The waste emulsion sludge treatment method comprises the following steps: 1, proportioning materials: quantitatively proportioning waste emulsion sludge and fly ash for next-step operation; 2, mixing: mixing materials proportioned in the proportioning step, namely repeatedly performing rolling, stirring and mixing operation thereon to obtain powdery particles; 3, discharging: outputting a finished product obtained in the mixing step, wherein the water content of thefly ash proportioned in the proportioning step is lower than or equal to 1%, the water content of the waste emulsion sludge is lower than or equal to 50%, and the content of particles with the particle size being smaller than or equal to 1mm in the proportioned fly ash is higher than or equal to 90%. According to the waste emulsion sludge treatment method, no chemical reaction occurs and no new pollutant is produced during treatment, two industrial wastes, namely the waste emulsion sludge and the fly ash, are treated, the obtained product can be fully burned as a fuel, the treatment cost is low, the treatment method is simple, the problem that the existing waste emulsion sludge is difficult to treat is solved, and industrialized application is easy.

Description

Technical field [0001] The invention relates to the field of industrial waste treatment methods, and more specifically to a waste emulsion sludge treatment method. Background technique [0002] Emulsion is a high-performance semi-synthetic processing metal. Its main components include water, mineral oil, surfactants, extreme pressure additives, etc., suitable for the processing of metals and their alloys, and are used to solve problems such as chip sticking during processing. Problems such as knots, tool wear, and surface contamination of the workpiece. Emulsion will inevitably undergo corruption during long-term use, and produce sediment or sludge, and produce odor, which spreads to the entire workshop and affects the operating environment of the workshop. Because waste emulsion sludge has a certain viscosity, peculiar smell, toxic and combustible , Is a hazardous waste, so it needs to be handled carefully. [0003] At present, a few companies are trying to filter the waste emul...
