Production process for preparing reclaimed rubber through sewage oil sludge

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.

Description

Technical field: [0001] The invention relates to a utilization method of sludge, in particular to a production process for preparing reclaimed rubber from sludge. Background technique: [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" in the oily waste category (HW08 items); according to my country's current crude oil production (16 × 108t / a), nearly one million tons of oily sands are produced every year, causing se...
