Detailed description of the invention
Other features of the invention and effect will be clearly presented in the embodiment referring to attached drawing, in which:
Fig. 1 is configuration schematic diagram, illustrates the embodiment of inventive article machine method for treating waste liquid.
Specific embodiment
The present invention will be described further with regard to following embodiment, however, it should be noted that the embodiment is only to illustrate
With, and it is not necessarily to be construed as the limitation that the present invention is implemented.
Refering to fig. 1, the embodiment of inventive article machine method for treating waste liquid includes that will contain the toolroom machine of oil-water emulsion
Waste liquid (being formed by oil-in-water emulsion with 150kg water by 17kg cutting oil) is heated to 65 DEG C by heater 1, then with liquid
The toolroom machine waste liquid is introduced into rotary packed bed 2 (substance of filling is wire netting) using constant power by body pump.
By being connected to the vacuum pump 3 of the rotary packed bed 2, make inside the rotary packed bed 2 for negative pressure, meanwhile, the rotation
Turn packed bed 2 to rotate with the revolving speed of 652rpm, to generate centrifugal force effect to the toolroom machine waste liquid, make in the oil-water emulsion
Water forms the low water-in-oil emulsion of moisture content after being removed, then flow out the rotary packed bed 2 and flow into the storage of toolroom machine waste liquid
In slot 4, after evenly mixing with the toolroom machine waste liquid, then is heated by the heater 1 and lead back to the rotary packed bed 2.
While the rotary packed bed 2 rotation, the water in the toolroom machine waste liquid is vaporized point from the toolroom machine waste liquid
From being subsequently introduced condenser 5 and condense and flow into recycle-water storage tank 6 and collect.Water temperature in the recycle-water storage tank 6 is about 24-
30℃。
After carrying out above-mentioned toolroom machine method for treating waste liquid 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 4.25h,
The pressure inside the rotary packed bed 2 is all measured respectively, the fluid temperature being introduced into the rotary packed bed 2, introduces the rotary filling
Fill the flow rate of liquid of bed 2, in the waste liquid moisture content (actual measurement) in the toolroom machine liquid waste tank 4, the water in the recycle-water storage tank 6
Weight, it is as a result as shown in table 1 below respectively.
Table 1
It can be seen from upper table 1 after the toolroom machine method for treating waste liquid 4h for carrying out the present embodiment, in the toolroom machine waste liquid
Waste liquid moisture content in storage tank 4 can be reduced to 7.65%, show the toolroom machine waste liquid from the oil-in-water emulsion contained originally
It is transformed into the water-in-oil emulsion that moisture content is lower than 10%；After the toolroom machine method for treating waste liquid 4.25h for carrying out the present embodiment,
Waste liquid moisture content in the toolroom machine liquid waste tank 4 can be greatly reduced by 90.0% to 0.20% that (de-water ratio is up to
99.6%), show that the oil-water emulsion that the toolroom machine waste liquid contains has formed Water-In-Oil emulsification of the moisture content significantly lower than 10%
Liquid.After the toolroom machine method for treating waste liquid 4.25h for carrying out the present embodiment, up to 88% can be recycled in the recycle-water storage tank 6
Water.In addition, the toolroom machine method for treating waste liquid of the present embodiment is not necessarily to discharge any waste liquid completely, the toolroom machine liquid waste tank 4
In liquid and the recycle-water storage tank 6 in water it is all recyclable recycle, and the liquid in the toolroom machine liquid waste tank 4 is above-mentioned
Each time of measuring point is all homogeneous liquid phase (oil-free water stratification phenomenon).
It is lower than in conclusion inventive article machine method for treating waste liquid can quickly make oil-water emulsion form moisture content
10% water-in-oil emulsion eliminates using demulsifier, surpasses during processing without carrying out general common demulsification processing
The modes such as filtering, high voltage electric field carry out the required problems faced that is demulsified.The present invention is sustainable to be effectively reduced a large amount of toolroom machine waste liquids
In moisture content, and can continuous processing oil-in-water emulsion or water-in-oil emulsion, and can get the water of not oil-containing for recycling again
It utilizes, so the purpose of the present invention can be reached really.
The above, only the embodiment of the present invention, when cannot be limited the scope of implementation of the present invention with this, i.e., it is all according to
Simple equivalent changes and modifications, all still belong to the scope of the present invention made by claims of the present invention and description.
