Detailed Description
The present invention will be specifically described below by way of examples. It should be noted that the following examples are given solely for the purpose of illustration and are not to be construed as limitations on the scope of the utility model, as many insubstantial modifications and variations of the utility model may be made by those skilled in the art in light of the above teachings.
Referring to fig. 1, the present invention provides a separation apparatus for polypropylene-containing liquid, comprising: the device comprises a liquid storage tank 1, wherein a partition plate 2 is arranged in the liquid storage tank 1, and the liquid storage tank 1 is separated into a water purification chamber 3 and a dust-containing water chamber 4 by the partition plate 2; a dust-containing water outlet 5 is arranged below the dust-containing water chamber 4, and a first purified water outlet is arranged below the purified water chamber 3.
The height that highly is less than liquid storage pot 1 of baffle 2, make adjacent water purification room 3 and the communicating with each other of 4 tops of dirt hydroecium, in the processing process, dirt-laden liquid flows into water purification room 3 at first, because polypropylene granule density is less than the liquid density in the polypropylene granule liquid, polypropylene granule floats on the liquid surface, when the liquid level risees gradually to baffle 2 height, the upper strata contains the liquid of polypropylene granule then from flowing into dirt hydroecium 4, thereby realize the separation of polypropylene granule and liquid, concentrated polypropylene granule waste liquid in dirt hydroecium 4 can be discharged through dirt-laden water outlet 5, the liquid of getting rid of the polypropylene granule is discharged through first water purification export.
