A thermal washing treatment method for oil waste

Abstract

The thermal washing treatment method of oil garbage of the present invention uses hot water to run through the whole treatment process, and the cleaning effect is also satisfactory without the action of detergent. Oil and water are separated and then processed and reused, and finally all of them are turned into resources. The whole system adopts a combination of multiple functions in one unit, which saves energy and reduces manufacturing costs. The separator will be equipped with screening, scrubbing, aeration, degreasing, and sanding in one machine, and it can be completed at one time without adding more equipment. The oil-water separator integrates the heating furnace, waste heat using oil-water separation, mud scraping and washing, and one machine has multiple functions. Plastic cleaning integrates hot sewage washing, shredding, cake pressing and exhaust gas recovery. All unit equipment such as mud oil removal and water removal, pretreatment tank and so on adopt one machine with multiple functions. Except for the infrastructure, all the equipment has the vehicle condition. The treatment process water is 100% recycled, and in general, there is no need to add new water or discharge it outside.

Description

technical field [0001] The invention relates to a technology for waste treatment and comprehensive utilization, in particular to a method for hot washing of oil waste. Background technique [0002] Oil waste mainly refers to the oily waste produced in the oil field during the oil extraction and transportation process, and the plastic diaphragm is laid on the ground before the operation. During the operation, oil, mud, water, chemicals, cleaning cloth, ground sand, soil mixture and plastic cloth are combined to form an oily waste. After the operation, the operation site should be cleaned up, and it should be manually removed and transported to the anti-seepage tank for treatment. Generally, the output of one operation is about 1-2 tons. The damaged crude oil pipeline spills out and is mixed with soil, sand, gravel, weeds and other objects on the ground. When repairing and plugging, the digging site needs to be enlarged, so the amount of oil and waste generated varies. doze...
