Problems solved by technology

[0002] At present, oily sludge sand is mainly produced in the oil exploration and development of oil fields. The composition of oily sludge sand itself is relatively complex, 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 due to the existence of components; the direct discharge of oily sludge will oc

Embodiment Construction

[0010] The oily sludge sand is separated from oil, water, mud and sand, and the particle size composition of the oily sludge sand is studied by the sieve analysis method. figure 1 .

[0011] It can be seen from the sieve analysis results that the particle size distribution of oil sludge sand is mainly concentrated in 0.1-0.85mm, the yield rate is 90%, the average particle size is 0.23mm, and the mud content is 1.74%, which is suitable for making unburned bricks. After repeated tests, it was found that the separated sand was mixed with 15%-50% cement, 10%-30% gravel, 1%-10% curing agent, and 20%-50% water in the mixer to make mortar, and then used a conveyor belt Transfer to the molding machine for molding to make machine-pressed non-burning bricks. After further adding fabrics, it can be made into colored bricks of different colors. After sampling and testing, the strength level reaches MU15. Dimensional deviation, appearance, freeze-thaw, frost, lime Bursting and other indic...

Abstract

The invention provides a method for recycling waste oil-containing sludge sand. The technical scheme is as follows: the method comprises the following steps: carrying out oil-water-sludge-sand separation, and researching the particle size composition of the oil-containing sludge sand by a sieve analysis process, wherein the particle size distribution of the oil-containing sludge sand is mainly concentrated at 0.1-0.85mm, the yield is 90%, the average particle size is 0.23mm, the sludge content is 1.74%, and the oil-containing sludge sand is suitable for making baking-free bricks; and adding 15-50% of cement, 10-30% of gravel, 1-10% of curing agent and 20-50% of clear water into the separated sand, stirring in a stirrer to make mortar, transmitting into a molding press by a transmission band, and carrying out molding pressing to obtain the mechanically pressed baking-free bricks. The invention effectively solves the problem that the sludge sand pollutes the soil and environment, saves the precious energy sources and abundant funds, can generate huge social benefit and economic benefit, and is suitable for wide popularization and use.

Description

Technical field: [0001] The invention relates to a utilization method of oily sludge sand, in particular to a resource utilization method of oily sludge sand. Background technique: [0002] At present, oily sludge sand is mainly produced in oil exploration and development in oil fields. 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 due to the existence of components; 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; The oily waste (HW08 item) listed in the "National Hazardous Waste Catalog" is estimated according to my country's current crude oil production (16×108t / a), and nearly one million tons of oily sand is produced every year, which is seriously polluted a...
