Abstract

The invention relates to the nuisanceless disposal field of chemical wastes and particularly relates to an environmental protection treatment process for the oily sludge. According to the process, a certain amount of oily sludge is delivered into a dilution tank, and then a certain amount of water is added into the dilution tank to dilute the oily sludge. After that, the oily sludge in the dilution tank is stirred and heated to be up to 60 DEG C to flow into an equalization basin. In the equalization basin, the oily sludge is reheated to be up to 80 DEG C to flow into a horizontal snail machine, and then an oil-water mixture and the solid sludge can be separated. The solid sludge is aired in the sun and then leaves a factory to be used for paving roads or baking bricks. The oil-water mixture is fed into an oil-water separator, and then the oil phase and the water phase are separated from each other. The oil phase flows into an oil sump and then is conveyed to an accumulator tank by a pump. The water phase flows into a water collecting tank and then is conveyed to a belt filter press by a pump to be further purified. The purified water directly flows into a fire pool to be recycled and reused. The above process is simple and convenient to operate, pollution-free to the environment and high in extraction yield of crude oil. Meanwhile, the obtained sludge and the water phase, which hare separated from each other, can be used for a second time. Therefore, the environmental protection treatment process for the oily sludge has good economic benefit and is environment-friendly at the same time.

Description

A kind of greasy dirt environment-friendly treating process
Technical field
The present invention relates to chemical industry waste product nuisanceless disposal field, particularly relate to a kind of greasy dirt environment-friendly treating process.
Background technology
The oil recovery of Changqing oilfields is larger, gathering station is more, the sump oil produced in process of production does not also have fine treatment process at present, in the period of outward transport waste treatment, due to the reason of long-term seepage, chronic pollution caused to neighbouring farmland, now seriously have impact on the quality of life of surrounding resident, jeopardize the physical and mental health of people.
Summary of the invention
The object of this invention is to provide a kind of greasy dirt environment-friendly treating process, thoroughly solve the pollution problem of greasy dirt, and extract crude oil from waste material.
Technical scheme of the present invention is: this technique by diluting, the separation of homogeneous, greasy filth, oily water separation, profit clean unit form, first oil sludge is quantitatively sent into diluting tank, add a certain amount of water dilute, stir, be heated to 60 DEG C after from flowing to homogeneous pond, reheat in homogeneous pond and enter horizontal screw machine after to 80 DEG C and isolate oil-water mixture and solid sludges, solid sludges can be used to pave the way or bake bricks by dispatching from the factory after air dry.Oil-water mixture enters water-and-oil separator, point fuel-displaced and water, and oil phase enters oil sump, again by pump delivery to gathering tank, aqueous phase enters water collecting basin, purifies waste water further to belt filter press by pump delivery, and the water after purification is directly from flowing to fire-water pond to recycle;
Preferably, described homogeneous pond adopts horizontal screw pump, and whole mediocre person can be made to expect Homogeneous phase mixing.
The present invention can realize following effect:
This technique have easy and simple to handle, environment is nuisanceless, crude oil extraction yield advantages of higher, and isolate that mud can be used for paving the way, brickmaking, aqueous phase directly from flowing to fire-water pond to recycle, can also reach the effect of environmental protection while having certain economic benefit.
accompanying drawing illustrates:
Fig. 1 is a kind of process flow sheet of greasy dirt environment-friendly treating process.
Numbering in accompanying drawing represents: F-1001: boiler house, V-1001: dump chest, V-1002: homogeneous pond, V-1003: oil sump, V-1004: oil tank, V-1005: pond, V-1006: oil trap; V-1007: grug feeding jar, M-1001: separating machine, M-1002: water-and-oil separator, M-1003: squeezing machine, X-1001: brow, X-1002: sewage work.
Embodiment
By reference to the accompanying drawings, the specific embodiment of the present invention is:
Embodiment 1
As shown in Figure 1, a kind of greasy dirt environment-friendly treating process described in the embodiment of the present invention, be made up of dilution, homogeneous, greasy filth separation, oily water separation, profit clean unit, first oil sludge is quantitatively sent into diluting tank, add a certain amount of water dilute, stir, be heated to 60 DEG C after from flowing to homogeneous pond, reheat in homogeneous pond and enter horizontal screw machine after to 80 DEG C and isolate oil-water mixture and solid sludges, solid sludges can be used to pave the way or bake bricks by dispatching from the factory after air dry.Oil-water mixture enters water-and-oil separator, point fuel-displaced and water, and oil phase enters oil sump, again by pump delivery to gathering tank, aqueous phase enters water collecting basin, purifies waste water further to belt filter press by pump delivery, and the water after purification is directly from flowing to fire-water pond to recycle; Described homogeneous pond adopts horizontal screw pump, and whole mediocre person can be made to expect Homogeneous phase mixing.

Claims (2)

1. a greasy dirt environment-friendly treating process, it is characterized in that, first oil sludge is quantitatively sent into diluting tank, add the dilution of a certain amount of water, stir, from flowing to homogeneous pond after being heated to 60 DEG C, reheat in homogeneous pond and enter horizontal screw machine after to 80 DEG C and isolate oil-water mixture and solid sludges, solid sludges can be used to pave the way or bake bricks by dispatching from the factory after air dry, oil-water mixture enters water-and-oil separator, divide fuel-displaced and water, oil phase enters oil sump, again by pump delivery to gathering tank, aqueous phase enters water collecting basin, purify waste water further to belt filter press by pump delivery, water after purification is directly from flowing to fire-water pond to recycle.
