Oily water output from a condenser, a washing tower, a deodorizing filter and an alkali tank in the process needs to be treated again in an oil-water separator, and a separated water phase enters a circulating water pool for secondary filtration, so that circulating water is provided for other equipment in the process. The existing circulating water tank has poor overflow effect, and the purification degree of water treatment is not high, so that circulating water with good purification effect is difficult to provide for other equipment.

The utility model has the following contents:

the utility model aims at overcoming the defects of the prior art and providing the circulating water tank for oil-water separation of the oily sludge process.

The utility model discloses a circulating water pond for water oil separating of oiliness mud technology comprises casing, inlet tube and packing layer, the bottom of casing be equipped with the inlet tube, the bottom in the casing is equipped with liquid distributor, the inlet tube links to each other with liquid distributor's feed liquor end, liquid distributor's top is equipped with the packing layer, the top of packing layer is equipped with the aeration pipe, is equipped with drain pipe and overflow pipe 7 on the lateral wall of casing, has fixed upper shed's filtration frame plate on the lateral wall of casing, the drain pipe is located and filters the frame plate.

As a further improvement of the utility model, the liquid outlet pipe and the overflow pipe are positioned at the same height.

As a further improvement, the relative two fixed blocks that are equipped with in position on the lateral wall of casing, aeration pipe swing joint is equipped with the aeration hole between two fixed blocks on the pipe wall of aeration pipe between two fixed blocks, and the aeration pipe is by motor drive, and the gas-supply pipe is connected to the inlet end of aeration pipe.

As a further improvement of the utility model, a three-way valve is arranged on the water inlet pipe, and the liquid outlet end of the overflow pipe is connected with the three-way valve.

The utility model discloses a circulating water pond for oil-water separation of oily sludge process provides a multi-level high quality circulating water pond of purifying, and it is through filler, aeration and filterable multistage purification, very big improvement the quality of circulating water after purifying, and it sets up the three-way valve simultaneously on the inlet tube, and the overflow pipe that will add links to each other with the three-way valve, solves the overflow problem on the one hand, and on the other hand can block the inlet tube in the overflow, feeds through the inlet tube after the water level descends again.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

In the figure: the device comprises a shell 1, a water inlet pipe 2, a liquid distributor 3, a packing layer 4, an aeration pipe 5, a liquid outlet pipe 6, a liquid overflow pipe 7, a filtering frame plate 8, a fixed block 9, an aeration hole 10 and a three-way valve 11.

The specific implementation mode is as follows:

the utility model discloses a circulating water pond for oil-water separation of oily sludge process comprises casing 1, inlet tube 2 and packing layer 4, the bottom of casing 1 be equipped with inlet tube 2, the bottom in casing 1 is equipped with liquid distributor 3, inlet tube 2 links to each other with the feed liquor end of liquid distributor 3, the aqueous phase that is separated by oil-water separator gets into the inside of casing 1 by inlet tube 2, carries out horizontal evenly distributed through liquid distributor 3 earlier, the external diameter of liquid distributor 3 is the same with the internal diameter of casing 1, be equipped with the through-hole on the top surface of liquid distributor 3, the aqueous phase flows out by the through-hole; a filler layer 4 is arranged above the liquid distributor 3, the water phase flows out uniformly from the liquid distributor 3 and is primarily purified by the filler layer 4, the filler in the filler layer 4 can be selected according to specific components to be removed in the water phase, and the filler is a commercially available product and can be used as long as the filler can achieve a preset effect; an aeration pipe 5 is arranged above the packing layer 4, two fixing blocks 9 are oppositely arranged on the side wall of the shell 1, the aeration pipe 5 is movably connected between the two fixing blocks 9, so that the aeration pipe 5 can rotate between the two fixing blocks 9, the aeration pipe 5 can also be driven by a motor to rotate, aeration holes 10 are formed in the pipe wall of the aeration pipe 5, the air inlet end of the aeration pipe 5 is connected with an air conveying pipe, chlorine can be introduced into the air conveying pipe for disinfection, air can also be blown in to bring floaters in the water phase to the water surface, and meanwhile, the aperture of the aeration holes 10 can be enlarged and reduced according to impurities in the water phase to form bubbles with different sizes, so that the effect of removing the impurities is achieved; a liquid outlet pipe 6 and a liquid overflow pipe 7 are arranged on the side wall of the shell 1, a filtering frame plate 8 with an upper opening is fixed on the side wall of the shell 1, the liquid outlet pipe 6 is positioned in the filtering frame plate 8, and water phase subjected to aeration treatment flows to other water-requiring equipment through the liquid outlet pipe 6 through the filtering frame plate 8 for recycling; the water inlet pipe 2 is provided with a three-way valve 11, the liquid outlet end of the overflow pipe 7 is connected with the three-way valve 11, when the liquid to be treated in the shell 1 is excessive, the liquid overflows from the overflow pipe 7, the end of the overflow pipe 7 of the three-way valve 11 is communicated with the water inlet end of the shell 1 at the same time, the water inlet end of the water inlet pipe 2 is blocked, and the water inlet of the water inlet pipe 2 is blocked while overflowing; when the water level drops, the water inlet pipe 2 can be communicated, and the overflow pipe 7 is blocked, so that the water phase smoothly enters the shell 1; the upper pipe wall of the overflow pipe 7 can be provided with a sensor, when the water surface rises to the top of the overflow pipe 7, the sensor can control the three-way valve 11 to change the direction, and then the communication between the overflow pipe 7 and the shell 1 is realized.
