Embodiment 1
[0020] Embodiment 1: The purification device includes a column separator 1, an inflow distribution device 2, a floating oil collection device 3, at least one inflatable cyclone separator 4, at least one self-priming microbubble generator 5 and at least one dissolved air separation microbubble generator. Bubble generator 6; in the column body of described purifying device, the upper part is column separator 1, and the lower part is inflatable cyclone separator 4; The filling point Q of the formula microbubble generator 5 is at the lower part of the cylinder.
[0021] The water inlet distribution device 2 is connected to the feeding pipe at the upper center of the column separator 1 .
[0022] One section of the self-priming microbubble generator 5 is connected to a circulating pump through a pipeline, and one section enters the column separator 1 through a pipeline and is connected to the tangential inlet Q of the inflatable cyclone.
[0023] Described gas-dissolved micro-bubb...
Embodiment 2
[0028] Example 2: In figure 1 Among them, along the column separator 1 from top to bottom, there are water inlet distribution device 2, gas filling point S of dissolved air precipitation microbubble generator 6, gas filling point Q of self-priming microbubble generator and gas cyclone separator 4 . The water inlet is at the middle and upper part of the cylinder, and is connected with the water inlet distribution device. The dissolved air precipitation microbubble generator 6 is placed outside the column, and a tube is connected with the dissolved air precipitation microbubble generator 6 and inserted into the column body, and the insertion position is in the middle of the column body. Further down is the gas-filled cyclone separator 4, and the lower segment of the gas-charged cyclone is an inverted cone 7. The self-priming microbubble generator 5 is placed outside the column, one section of which is connected to the outlet of the circulation pump through a pipeline, and the ...
