Center column jecket, water distribution system and collecting system etc. are fixed on the sidewall of this degreasing unit.
In engineering of water treatment, it is to process such waste water that the petrochemical industry oil refining wastewater containing innage carries out oil removing
The first step, follow-up also will be to having eliminated overwhelming majority oil and such waste water of mud be removed further
Organic pollutions etc. process.Stable in order to ensure the water inlet in subsequent handling, participate in Fig. 2 and Fig. 3, this oil removing
Device also needs to the water tank 60 including being arranged in degreasing unit exterior side wall;Water tank 60 is provided with set
Cylinder valve 61;Water tank 60 is connected with outlet 2 by pipeline.Adjusted by the freeboard of telescoping valve 61
The balance of water saving position, makes water tank stable water outlet, stable to ensure the water inlet in subsequent handling.
As a kind of improved procedure of this tank type degreasing unit, first order sparge pipe and first order collector pipe
Structure is identical;First distribution drum is identical with the structure of the second distribution drum;Second level sparge pipe catchments with the second level
The structure of pipe is identical;Second iiared port direction is downward.Structure described herein is identical refers to the first grating
Water pipe is identical with the length of first order collector pipe and diameter;The length of the first distribution drum and the second distribution drum and directly
Footpath is identical;Second level sparge pipe is identical with the length of second level collector pipe and diameter.
See Fig. 4, as the another kind of improved procedure of this tank type degreasing unit, this degreasing unit multiple first
Distribution drum 24 is positioned in same level, and is evenly distributed on the circumference with distributing water room 21 as the center of circle;With same
The first horn mouth 25 that one the first distribution drum 24 is connected is positioned in same level, and be evenly distributed in
This first distribution drum 24 is on the circumference in the center of circle;Seeing Fig. 5, another as this tank type degreasing unit changes
Entering mode, multiple second distribution drum 33 are positioned in same level, and are evenly distributed in and with center column jecket 10 are
On the circumference in the center of circle;The second horn mouth 34 being connected with same second distribution drum 33 is positioned at same level
On, and be evenly distributed on this second distribution drum 33 circumference as the center of circle.
It will be appreciated by persons skilled in the art that the profile of tank type degreasing unit is generally cylindrical, this
Skilled person can design the first distribution drum of being connected with distributing water room according to degreasing unit diameter
The first bell-mouthed quantity that quantity is connected with each first distribution drum, the quantity of the second distribution drum and with
The second bell-mouthed quantity that each second distribution drum is connected.In actual applications, each first distribution drum
All can be connected by second level sparge pipe and 3,4,5 or 6 the first horn mouths, preferably 4
One horn mouth is to connection (as shown in Figure 4);Each second distribution drum all can by second level collector pipe 3,4,
5 or 6 the second horn mouths are connected, and preferably 4 the second horn mouths are connected (as shown in Figure 5).
On the basis of the above-mentioned various improved procedures of this tank type degreasing unit, and in the first distribution drum
Identical with the quantity of the second distribution drum, the first bell-mouthed quantity of being connected with each first distribution drum and with
In the case of the second bell-mouthed quantity that each second distribution drum is connected is identical;Multiple first distribution drum are enclosed
After distributing water room horizontally rotates 15 ° or anticlockwise horizontal rotation 15 ° clockwise, its just throwing in the horizontal plane
Shadow and multiple second distribution drum orthographic projection conllinear in the horizontal plane.The design of this structure makes water distribution system cloth
Water is uniform, and collecting system water inlet uniformly, reduces the resistance in water distribution and water collecting process.
Further, in actual applications, the quantity of the water inlet of this tank type degreasing unit is 2, and enters

It is arranged on the inside of degreasing unit, and the position at place, inverted U overflow pipe 5 upper end is higher than annular collection tank
The position at 40 top edge places.When entering the pending wastewater flow rate of this degreasing unit more than this degreasing unit
During the big storage water yield, unnecessary pending waste water is discharged by inverted U overflow pipe.
Seeing Fig. 1 and Fig. 2, as a kind of improved procedure of this tank type degreasing unit, this degreasing unit also wraps
Including the breather 6 being arranged within degreasing unit, breather 6 one end is connected with distributing water room 21, separately
One end is higher than the default maximum storage liquid level of this degreasing unit so that the air pressure in degreasing unit is with extraneous
Air pressure balance.It should be noted that presetting maximum storage liquid level is the reason when designing this degreasing unit
The maximum water storage height drawn in opinion.
Additionally, see Fig. 6, in actual applications, spoil disposal 50 includes being responsible for 51 and arm 52;It is responsible for 51 and props up
Offer on the tube wall of pipe 52 multiple enter mud hole 53;Discharge pipeline 50 in dendritic distribution, makes bottom degreasing unit
Obtain discharge pipeline and be distributed in the bottom of degreasing unit to greatest extent, so that heavy oil and float are as much as possible
Fall in discharge pipeline, and in order to avoid blocking discharge pipeline, the caliber of arm is preferably equal to or greater than 150mm.
Each embodiment in this specification all uses relevant mode to describe, phase homophase between each embodiment
As part see mutually, what each embodiment stressed is the difference with other embodiments.
The foregoing is only preferred embodiment of the present utility model, be not intended to limit of the present utility model
Protection domain.All made within spirit of the present utility model and principle any amendment, equivalent, change
Enter, be all contained in protection domain of the present utility model.
