Problems solved by technology

[0002] Oily sludge sand is mainly produced by oil fields in oil exploration and development. Oily sludge sand itself has complex components, containing a large amount of aged crude oil, wax, colloid, suspended solids, salts, acid gases, etc. It takes hundreds of years to completely decompose under natural conditions; the direct discharge of oily sludge will occupy a large amount of land, and the toxic substances contained in it will pollute water, soil and air, and deteriorate the ecological environment; at present, oily sludge sand in oil fields has been listed Included in the "National Hazardous Waste Catalog" as oily waste (HW08 item); according to the current crude oil production (16×108t / a) in my country, nearly one million tons of oily sand is produced every year, causing serious pollution and urgently needed to be solved

Embodiment 1

[0008] Example 1: After the sludge is cleaned, it is mixed with waste tire powder, rubber hose powder, and rubber shoe powder in a ratio of 1:2, then added to the rubber powder activation tank, heated to 180 degrees while stirring, and kept warm for 2 hours. Exhaust for 1 hour, and then discharge the material to form activated rubber powder of different qualities, which are refined into regenerated rubber films of different thicknesses. Further mixing and vulcanization can also be made into rubber products such as road speed bumps, realizing the resource utilization of waste.

Embodiment 2

[0009] Example 2: After the sludge is cleaned, it is mixed with waste tire powder, hose powder, and rubber shoe powder in a ratio of 1:5, and then added to the rubber powder activation tank, heated to 220 degrees while stirring, and kept warm for 5 hours. Exhaust for 2 hours, and then discharge to form activated rubber powder of different qualities, which are refined into recycled rubber films of different thicknesses. Further mixing and vulcanization can also be made into rubber products such as road speed bumps, realizing the resource utilization of waste.

Embodiment 3

[0010] Example 3: After cleaning, the sludge is mixed with waste tire powder, rubber hose powder, and rubber shoe powder in a ratio of 1:9, then added to the rubber powder activation tank, heated to 260 degrees while stirring, and kept warm for 10 hours. Exhaust for 3 hours, and then discharge the material to form activated rubber powder of different qualities, which are refined into recycled rubber films of different thicknesses. Further mixing and vulcanization can also be made into rubber products such as road speed bumps, realizing the resource utilization of waste.

Abstract

The invention provides a production process of waste utilization for preparing reclaimed rubber through sewage oil sludge. The technical scheme is as follow: mixing sewage oil sludge after being cleaned up with waste tire powder, hose powder, galoshes powder in different proportions of 1:2-1:9 and adding into a crumb activation tank, stirring and heating up to 180-260 DEG C, insulating for 2-10 hours, exhausting the gas at the interval of 1-3 hours, then discharging, to form activated rubber powder different qualities which is refined into recycled rubber film with different thicknesses. The production process provided by the invention solves the problem of sewage oil sludge contaminating soil and the environmental problem. Changing waste into renewable resource saves valuable energy and a lot of money, has an enormous social and economic benefit, and is suitable for popularization and application.
