Problems solved by technology

It has the following disadvantages: ① Large-scale incineration equipment is required, which requires large investment and high cost; ② Various combustion-supporting fuels need to be added, which is troublesome to operate and further increases the cost; ③ During the incineration process, toxic gases such as sulfur dioxide and greenhouse gases such as carbon dioxide will be produced. Gas and various dust particles cause extremely serious damage to the atmospheric environment; ④ crude oil cannot be recovered
It has the following disadvantages: ①The requirements for the reaction conditions are extremely high, and it has high technical content; ②The processing cost is high; ③The operation is complicated and inconvenient to use
It has the following disadvantages: ① It has high technical requirements; ② The reaction cycle is too long and the efficiency is too low
It has the following disadvantages: the components of the washing solution are all chemical reagents, which are highly toxic and pollute the environment
[0010] As mentioned above, there are many methods for dealing with oil sludge at present, but there are more or less deficiencies and shortcomings in various chemical detergents and cleaning processes.

Embodiment 1

[0029] A method for cleaning oily sludge using the above cleaning agent, comprising the steps of:

[0030] Step S1, first extract tea saponin, the operation is as follows: put 20g of tea seed powder into a Soxhlet extractor, add 300ml of absolute ethanol, in order to prevent the tea seed powder from clogging the extraction tube, wrap the powder with filter paper. Then heat with an electric heating mantle and extract for 6-7 hours until the color of the solution in the round bottom flask changes from colorless to yellow; put the obtained yellow solution in an oven for drying, and grind the dried solid matter with a mortar , that is, tea saponin is obtained; the extraction time must be long, so that the tea saponin in the tea seed powder is fully dissolved in absolute ethanol, which is beneficial to the improvement of the cleaning effect. Then, configure a cleaning agent: dissolve 0.6g tea saponin, 0.3g sodium silicate, 0.05g sodium bicarbonate, 0.05g AEO (fatty alcohol polyoxye...

Abstract

The invention discloses an oil-containing sludge cleaning agent. The oil-containing sludge cleaning agent comprises a primary cleaning agent and a secondary cleaning agent; the primary cleaning agentcontains tea saponin, sodium silicate, fatty alcohol polyoxyethylene ether, and sodium bicarbonate; the secondary cleaning agent comprise fatty alcohol polyoxyethylene ether, and sodium bicarbonate; the primary cleaning agent is prepared through dissolving of tea saponin, sodium silicate, fatty alcohol polyoxyethylene ether, and sodium bicarbonate in water; and the secondary cleaning agent is prepared through dissloving fatty alcohol polyoxyethylene ether, and sodium bicarbonate in water. The cleaning method used for washing oil-containing sludge comprises following steps: primary cleaning, primary settlement, secondary settlement, secondary cleaning, and drying. The oil-containing sludge cleaning agent cleaning process is simple, is high in efficiency, and low in comprehensive energy consumption; 80 to 90% of oil in oil-containing sludge can be washed away, and the highest oil removing rate is 90% or higher.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel oily sludge cleaning agent and a cleaning process. Background technique [0002] With the rapid development of the world economy, the demand for oil is increasing, and the number of oil wells and refineries is also increasing rapidly. In the process of oil exploration, mining, refining, tank cleaning, storage and transportation, a large amount of oil products, soil and other impurities form oily sludge due to accidents, leakage, leakage, natural settlement and other reasons. This kind of sludge contains a large amount of toxic substances, which will cause continuous harm to the ecological environment and human health. Therefore, the harmless treatment of oily sludge is an important issue in the petroleum industry. [0003] The existing technologies for treating oil sludge mainly include incineration, thermal decomposition, biological treatment and therm...
