Method for pretreating oil sludge waste in hazardous waste incineration disposal

Abstract

The invention discloses a method for pretreating oil sludge waste in hazardous waste incineration disposal. The method comprises the steps that oil sludge model waste, lime and water are taken, the lime is ground through crushing equipment, the oil sludge model waste and the ground lime are mixed, water is added for stirring in the mixing process, and a mixed body is prepared; the mixed body is placed in a reaction still to be boiled, and elemental sulfur in the oil sludge model waste is converted into polysulfide; and the boiled material in the reaction still is taken out, pretreatment is completed, in the pretreatment process, the lime, the water and the oil sludge model waste react together to generate the polysulfide, then the situation that in the later treatment process, sulfide is heated to generate sulfur dioxide gas is effectively avoided, and meanwhile in order to enable the elemental sulfur in the oil sludge model waste to be completely converted, the amount ratio of the lime, the water and the oil sludge model waste is controlled. According to the method, the process is added in the waste pretreatment process, and sulfur dioxide gas can be prevented from being generatedlater.

Description

technical field [0001] The invention relates to the field of oil sludge treatment, in particular to a pretreatment method for oil sludge waste in hazardous waste incineration disposal. Background technique [0002] The clay model is a car body model that is sculpted with clay in traditional body design. It is mainly used to express the actual effect of car styling for the approval of designers and decision makers. In the design process, computer aided design has been widely used, but the clay model is still widely used because of its high efficiency and authenticity of expression. Since modeling is actually a sculpture process, it is necessary to use clay that is easy to process and modify by hand. In the production and development of clay models, the sludge used in body modeling is similar to ordinary plasticine, but the requirements are higher. The main components of sludge are talcum powder, vaseline, industrial wax and sulfur. The stylist spreads it on the wooden skele...

AI Technical Summary

Problems solved by technology

[0003] The traditional treatment method has the following disadvantages: Since the sludge model waste contains monomeric sulfur, in the treatment of the sludge model waste, sulfur dioxide gas will be generated when the waste is processed at a high temperature (1000 degrees Celsius) in the later stage, which will increase the post-treatment process.
