In the such scheme, oil trap one side is provided with oil outlet pipe in the described separate tank.
In the such scheme, described level control valve is placed on the water shoot.
In the such scheme, described device also is provided with a cover plate that can cover whole separate tank.
In the such scheme, describedly be provided with electric heating tube in the oil trap bottom.
In the such scheme, described separate tank the bottom be provided with a plurality of blow-down pipes.
The water-and-oil separator of the above technology of application of indication of the present invention, its beneficial effect is as follows:
1, the existing same category of device of comparing, present device has improved the efficient of oily water separation, can make the content＜10mg/L of oil in the water outlet.
2, present device can realize automatic oil draining.By adjusting mouth of a river liquid level, can realize automatic oil draining, save manpower and running cost, improve the efficient of oily water separation simultaneously.
3, in order to reduce the volume of equipment, present device adopts special swash plate oil removal plant, and this swash plate can shorten the distance that oil slick rises, thereby reduces the residence time of water and oil.
4, in order to prevent that cold district oil content in winter viscosity from increasing, mobile poor, the oil extraction difficulty, the present invention's design is established electric heating tube in the oil trap bottom, so that oil extraction is smooth and easy.
5, the present invention is owing to adopt cavitation air flotation principle, shallow pond sedimentation theory and incorgruous flow point from principle and turbulent boundary layer principle, improved the release surface that the unit pond holds, the effect of oily water separation is improved widely, shortened retention time of sewage, reduce volume of equipment greatly, saved floor space and cost.
6, present device reliable operation, work-ing life is extremely long, need not add any reagent and medicine, non-secondary pollution.
7, the present device installation and maintenance are simple and convenient: just can use as long as connect water inlet pipe, rising pipe, need not special messenger's during-operation service, a regular oil extraction of need gets final product.
8, present device is applicable to all oil kinds, oil-feed concentration is unrestricted: can be widely used among the waste water treatment engineering that contains natural oil and petroleum products, tar and tar fraction, vegetable and animals oils and lanolin etc., be specially adapted to the processing of catering industry oily(waste)water.
Description of drawings:
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the sectional structure chart of water-and-oil separator of the present invention.
Fig. 2 is the plan structure figure of water-and-oil separator of the present invention.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As depicted in figs. 1 and 2, water-and-oil separator of the present invention, this device main body comprises a separate tank 1, is provided with the water inlet pipe 2 that is used for injecting oily(waste)water at the separate tank head end; Be provided with foreign material discrete blocks 3 near 2 mouthfuls of the water inlet pipes in separate tank, this is stated foreign material discrete blocks 3 and is used for large granular impurity in the separating and filtering oily(waste)water; Be mounted with cavitation air flotation aerator 4 in separate tank, this is stated cavitation air flotation aerator 4 and is attached on by a large amount of micro bubbles that produce in oily(waste)water and oil droplet is floated to liquid level around the olesome rapidly.
Also be provided with swash plate oil removal plant 5 in the separate tank 1 into the distance that shortens the oil slick rising; Be close in the not far separate tank of swash plate oil removal plant 5 and be provided with the oil trap 6 that is used for holding the rising oil slick, this oil trap one side is provided with oil outlet pipe 7, and the oil trap bottom is provided with electric heating tube 8.
Be provided with the water shoot 9 of a band filter core 10 at the end of separate tank 1, this water shoot 9 connects a fluid level control device 11, and this fluid level control device 11 comprises a level control valve 12 that is used for controlling the water shoot aquifer yield, and this level control valve 12 is placed on the water shoot 9.
It needs to be noted that water-and-oil separator of the present invention also is provided with a cover plate 13 that can cover whole separate tank 1.Simultaneously separate tank the bottom be provided with several blow-down pipes (14a, 14b, 14c, 14d).
Below be the concrete operational process of present device:
At first, make the water inlet pipe access arrangement of oily(waste)water, by the foreign material discrete blocks, oarse-grained impurity is separated then at this from separate tank.Then enter the cavitation air flotation stage, around a large amount of micro bubbles that produce under the effect of cavitation air flotation aerator are attached on olesome, make oil droplet under the lifting effect of microbubble, reduce its proportion, and float rapidly to liquid level, when treating that the liquid level oil slick reaches certain thickness, close or turn down the control valve of liquid automatic control device, liquid level is raise, add the effect of swash plate oil removal plant, sewage enters the swash plate disengaging zone from the cavitation air flotation district makes oil slick rapidly increase to liquid level.And the oil slick that floats on the liquid level can flow into oil trap automatically, and is recycled to oil storage barrel by oil outlet pipe.
In addition, in order further to strengthen the oil removal efficiency of water outlet, end at separate tank is placed the filter core that adopts special filtrate to be made into, this filtrate has the selection adsorptivity to oil, can an oil suction not absorb water, make remaining micro-oil droplet particle be adsorbed onto that water then drains into the equipment rising pipe by filter core on the filtering material.
Facts have proved, but the present invention the oil slick more than the particle diameter 60um can be removed more than 90%, the content of externally discharged waste water vegetable and animals oils is lower than " integrated wastewater discharge standard " primary standard (10mg/L) in (GB8978-1996).
