Problems solved by technology

[0006] Aiming at the problems in the prior art that the waste emulsion sludge is difficult to handle, the treatment process is complicated, the cost is high, and secondary pollution is easy to occur during the treatment process, the present invention provides a waste emulsion sludge treatment method. The waste emulsion oil sludge and fly ash are treated as two kinds of industrial wastes, and the obtained products can be fully burned as fuel, and no new pollutants are produced during the treatment process. The process is simple and the cost is low.

Embodiment 1

[0045] A kind of waste emulsion sludge processing method of the present embodiment comprises the following steps:

[0046] 1. Batching, after quantitatively proportioning waste emulsion oil sludge and fly ash, proceed to the next step;

[0047] 2. Mixing, mixing the materials prepared in the batching step, and making powdery particles through repeated rolling, stirring and mixing operations;

[0048] 3. Discharging, outputting the final product of the mixing step.

[0049] When the existing waste emulsion is treated, the chemical treatment method is mostly used, and after the 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 processed products and accompanying substances to meet the discharge standards, and the discharge will increase the burden on...

Embodiment 2

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

[0091] To ensure combustibility and combustion effect of the product obtained by this method, the water content of the final product must be very low. Therefore, when batching, it is necessary to select materials for raw materials (waste emulsion oil sludge) and additives (fly ash). Select materials that meet the above water content standards for batching. When the water content of fly ash is greater than 1%, the mixed product 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 oil sludge is greater than 50%. In order to absorb...

Embodiment 3

[0093] A method for treating waste emulsion oil sludge in this embodiment is further improved on the basis of Embodiment 2. Before the batching step starts, the material selection step is carried out first, and the particle content of the particle size ≤ 1mm in the mixed fly ash is ≥ 90%.

[0094] In actual operation, it is found that the particle size of fly ash affects the mixing effect of materials in the mixing process, thereby affecting the combustion effect of the mixing product. , there are more solid slag and agglomerate materials in the mixing product, which cannot be fully burned during combustion, and will affect the forward movement of the fuel delivery equipment during combustion. Therefore, before batching, the pulverized coal The ash is first selected as a material, so that the particle content of the particle size ≤ 1mm in the mixed fly ash is ≥ 90%, so as to ensure the mixing effect.

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, in particular to a treatment method for waste emulsion oil sludge. Background technique [0002] Emulsion is a high-performance semi-synthetic processing metal, its main components include water, mineral oil, surfactants, extreme pressure additives, etc. Knot, tool wear, workpiece surface contamination and other problems. The emulsion will inevitably corrode during long-term use, producing sediment or sludge and other substances, and producing odor, which spreads to the entire workshop and affects the operating environment of the workshop. Because the waste emulsion sludge has a certain viscosity, odor, poisonous and flammable , are hazardous waste and therefore need to be handled with care. [0003] At present, a small number of enterprises are trying to filter the waste emulsion slag and send it to the boiler system for combustion, but because the fuel contains solid slag and...
