Embodiment Construction

[0035] In conjunction with the accompanying drawings, a comprehensive utilization device for oily pollutants includes a separation unit 1 and a dehydration and desorption unit 2. The separation unit 1 includes a raw material adjustment pool 1-1 and a cyclone air flotation device 1-2. The dehydration and desorption Unit 2 includes a filter press 2-1, a drying crusher 2-2, a circulating fluidized bed 2-3, a cyclone separator 2-4, an oil-gas condensation separator 2-5 and a hot blast stove 2-6. A stirrer 13 is arranged inside the raw material blending pool 1-1, a raw material inlet 11 and a medicament inlet 12 are arranged at the top of the raw material blending pool, and a material outlet 14 is arranged at the bottom of the raw material blending pool. The swirl air flotation device 1-2 includes a shell, and the shell is divided into a swirl mixing section and an air flotation section connected successively from bottom to top. The swirl mixing section is in the shape of a cone. T...

Abstract

The invention discloses an oily pollutant comprehensive utilization apparatus. The oily pollutant comprehensive utilization apparatus comprises a separation unit and a dehydration desorption unit, wherein the separation unit comprises a raw material blending pond and a cyclone air floater, the dehydration desorption unit comprises a press filter, a drying breaker, a cyclic fluidized bed, a cycloneseparator, an oil gas condensation separator and a hot blast heater. Oily pollutants are sent into the separation unit, a separated oil product is stored in an oil tank, discharged dregs are sent into the dehydration desorption unit, a heating desorption apparatus such as the cyclic fluidized bed is arranged in the dehydration desorption unit, the dregs are heated to 450 to 650 DEG C, small molecular organic matters in the dregs are heated and desorbed, the macromolecular organic matters are heated and decomposed to obtain an oil product with high additional value, and the discharged solid dregs satisfy the corresponding national standard and regulations. By adopting the oily pollutant comprehensive utilization apparatus, a brand new way is provided for harmlessly recycling the oily waste; the oily waste is converted into treasure, and a great amount of oil resources with high additional value can be recycled from the oily waste; and the environmental protection pressure of the enterprises and society can be alleviated.

Description

technical field [0001] The invention relates to the field of solid waste / hazardous waste treatment, in particular to the treatment of oily pollutants, and more specifically to a comprehensive utilization device and process for oily pollutants. Background technique [0002] Oily pollutants are one of the main pollutions produced in the petroleum and petrochemical industry during the production process of petroleum exploration, storage and transportation, and refining. Oily pollutants contain high oil content, and contain a variety of chemicals, which are extremely difficult to separate and treat, and contain a large number of bacteria, toxic substances, heavy metal salts and other complex components with high toxicity, and are listed as HW08 hazardous waste in the "National Hazardous Waste List" . If it is discharged directly without treatment, it will cause serious pollution to the surrounding environment and even affect human health. Therefore, the treatment of oily pollu...
