Problems solved by technology

However, the mud and sand separated by this method are generally incinerated and then landfilled or directly landfilled to achieve the purpose of harmless treatment of oil mud and sand, which costs treatment costs and wastes sediment resources, and also occupies a large amount of land.

Embodiment 1

[0035] Embodiment one: a kind of method using oil sludge sand as raw material to produce ceramsite, described method comprises the following steps:

[0036] a. Send the collected oil sludge sand to the ceramsite molding machine for granulation treatment to make granular ceramsite blanks; when the oil content in the oil sludge sand raw material is less than 3%, and the water content in the mud is less than 10%, it can be directly formed , that is, the oil sludge sand is directly sent to the ceramsite molding machine for granulation treatment without any pretreatment, and is made into a granular ceramsite blank.

[0037] Use the conveyor belt to transport the collected oil sludge sand to the ceramsite molding machine, and according to the requirements of different ceramsite products, it can form block, spherical, and oval products; this example uses a conventional ceramsite molding machine, and you can choose B18- 003 fly ash ceramsite molding machine.

[0038] b. Send the gran...

Embodiment 2

[0041] Embodiment two: referring to Fig. 1, a kind of method for producing ceramsite with oil mud sand as raw material, described method comprises the following steps:

[0042] a. Use a mixing container, put the collected oil sludge sand in the mixing container, add dilution water, start the agitator to stir for 10 minutes, and process the oil sludge sand into oil sludge mortar, the water content in the oil sludge mortar is 60-80 %;

[0043] b. The oil sludge mortar is sent to the sludge sieve through the first-stage mortar pump for screening treatment to obtain the oil sludge sand fine slurry; in this embodiment, the SYZ series vibrating screen can be used as the sludge screen, and its purpose is to screen out large pieces Foreign matter such as sand, impurities and cotton yarn;

[0044]c. Send the oil sludge sand fine slurry into the solid-liquid separator for solid-liquid separation treatment to form waste oil, sewage and deoiled sand mud respectively, and detect the deoil...

Abstract

This invention relates to a method for producing ceramicite by using oily sands as raw material. The procedures are: (a), raw material oily sands are fed into a vessel with its agitator; adding water for dilution and agitating for ten minites, so the sands are treated into sand-slurry; (b), said sand-slurry is pumped, by using first sand-slurry pump, into slurry sieve to obtain fine sand slurry; (c), the fine sand slurry is pumped into a solid / liquid separator, and separated into oily dirt, waste-water and deoiled sand mud; (d), said mud is then fed into ceramicite formation machine to produce semifinished products: (e), the same is then fed into a rotary kiln and sintered under temperature of 800-1450deg.C for 50-60 minites, after natural cooling to obtain the final products with the volume-weight of 300-1500kg / m3.

Description

technical field [0001] The invention relates to a method for producing ceramsite with oily sand as raw material. The method is to granulate the deoiled sand mud (or add clay and other auxiliary materials to the deoiled sand mud to make composite clay) to produce Granular ceramsite blanks are sintered at high temperature to produce ceramsite products. Background technique [0002] Oily sludge, also known as oily sludge, is produced in petroleum production activities, mainly from various links in crude oil extraction, transportation and processing, and is a mixture of oil, mud, sand, and water polluted by crude oil and other organic substances. Generally, the oil content in sludge is 10-50%, and the water content is 25-50%. In my country's petrochemical industry, an average of 800,000 tons of oil sludge sand is produced every year; Shengli Oilfield produces more than 100,000 tons of oil sludge sand every year, and Henan Oilfield Produces about 50,000 tons of oil sludge sand. ...
