Description

A kind of oily-water seperating equipment
The utility model relates to oily-water seperating equipment, and particularly oil-containing, emulsifying liquid waste water carry out the device of water-oil separating behind chemical demulsification.
In oil-containing, emulsifying liquid waste water, because of the existence of surfactant makes oil-water emulsion, oil is dispersed in (average grain diameter is less than 1 micron) in the water with atomic little particle glue, gelled fuel integument-COO or-C-SO 3-group surrounds, and forms the colloidal particles with identical negative electrical charge, and electric exclusion makes colloidal particles keep high degree of dispersion and stable status mutually.
Chemical demulsification is exactly to add a certain amount of metal species electrolyte in oil-containing, emulsifying liquid waste water, the metal cation that its hydrolysis produces is with colloidal particles electrically neutralize and colloid chemistry is taken off surely, and gluey oil droplet particulate forms oil droplet through the cohesion that runs foul of each other and floats upward and finish breakdown of emulsion.
Oil-containing, emulsifying liquid waste water also need carry out water-oil separating behind chemical demulsification, but the oil-water separation method that adopts so far both at home and abroad is all very undesirable.The flocculation sediment partition method, its disengaging time long (1-2 days), floor space is big, and clear liquid turbidity height, and sump oil ash content height causes secondary pollution etc., thereby is difficult to promote; The flocculation-air floating method adopts dissolved air flotation usually, (reaches 10 because of concentration of suspension behind the breakdown of emulsion is too high 4Ppm), the air capacity limited (40mL/L) that air-dissolving air-float produces is difficult to complete air supporting, oil-containing, emulsifying liquid waste water have to be diluted at double, and repeatedly air supporting again, therefore investment is expensive, operating cost is high, also is difficult to promote.
The purpose of this utility model is: a kind of oily-water seperating equipment is provided, and it can effectively overcome the corresponding disadvantage of above-mentioned two class oil-water separation methods, promotes easily.
For achieving the above object, solution of the present utility model is: it comprises air flotation slot and sump oil collector groove, the sump oil collector groove is arranged on the periphery of air flotation slot, the top of sump oil collector groove is provided with the outer comb of sump oil, the bottom of air flotation slot is provided with the waste water feed tube, and the bottom of air flotation slot is provided with the micro air bubble generator.
The utility model adopts the micro air bubble generator (as the patent No.: 97241057.0 disclosed micro air bubble generators), compressed air is by the micro air bubble generator, in oil-containing, emulsifying liquid waste water, directly produce a large amount of micro air bubbles, oil droplet behind the breakdown of emulsion is floated rapidly by bubble trap immediately and realizes the profit initial gross separation, and because of the micro air bubble amount big, oil-containing, emulsifying liquid waste water do not need dilution, and an air supporting can be finished water-oil separating; Secondly, ultra-fine bubble generator is housed in air flotation slot, and its bubble diameter<50 micron can make in the breakdown of emulsion clear liquid after the profit initial gross separation fine suspension realize the high accuracy Separation of Solid and Liquid, and quickening oxidation operation degraded in the breakdown of emulsion clear liquid, realization clear liquid COD is up to standard directly to efflux; The 3rd, micro air bubble floats in a large number, exists tangible stirring on liquid level, and water content is also higher in the sump oil layer, is difficult for compiling and gathers.The utility model internal layer is an air flotation slot, skin is the sump oil collector groove, and when sump oil gathered suitable thickness in the sump oil collector groove after, the outer comb oil extraction hand valve timing of sump oil of opening the sump oil collector groove was discharged in the sump oil groove, overcome the various disadvantages of above-mentioned two class oil-water separation methods, promoted easily.
Below in conjunction with accompanying drawing, embodiment is described in further detail to the utility model:
Fig. 1 is the utility model embodiment 1 structural representation
Fig. 2 is the utility model embodiment 2 structural representations
Fig. 3 is the utility model embodiment 3 structural representations
The utility model embodiment 1 as shown in Figure 1, it is made up of air flotation slot 1, sump oil collector groove 2, sump oil collector groove 2 is arranged on the periphery of air flotation slot 1, the bottom of air flotation slot 1 is provided with the micro air bubble generator 5 of bubble diameter<50 micron, and (patent No.: 97241057.0 disclosed micro air bubble generators), micro air bubble generator 5 provides compressed air by air inlet pipe 6; The top of sump oil collector groove 2 is provided with the outer comb 3 of sump oil; The bottom of sump oil collector groove 2 is provided with clear liquid drain pipe 4; The bottom of air flotation slot 1 is provided with waste water feed tube 7, steam-heating pipe 8 and chemical demulsifier liquid distributor 9, makes air flotation slot 1 become air supporting breakdown of emulsion groove.
The utility model embodiment 2 as shown in Figure 2, it is made up of air flotation slot 1, sump oil collector groove 2 and peripheral air flotation slot 11, sump oil collector groove 2 is arranged on the periphery of air flotation slot 1, be provided with a peripheral air flotation slot 11 between air flotation slot 1 and the sump oil collector groove 2, the bottom of air flotation slot 1 and peripheral air flotation slot 11 is provided with the micro air bubble generator 5 of bubble diameter<50 micron; Micro air bubble generator 5 provides compressed air by air inlet pipe 6; The bottom of peripheral air flotation slot 11 is provided with clear liquid drain pipe 4, will handle clear liquid and discharge.The top of sump oil collector groove 2 is provided with the outer comb 3 of sump oil, the bottom of sump oil collector groove 2 is communicated with air flotation slot 1 usefulness pipeline 10, owing to have a large amount of micro air bubbles in the air flotation slot, make its liquid specific gravity be slightly less than liquid specific gravity in the sump oil feeder, thereby the air flotation slot liquid level will be higher than the sump oil feeder, thus on the sump oil that floats on air flotation slot 1 liquid level can all be flowed to automatically in the sump oil collector groove; The bottom of air flotation slot 1 is provided with waste water feed tube 7, steam-heating pipe 8 and chemical demulsifier liquid distributor 9, makes air flotation slot 1 become air supporting breakdown of emulsion groove.
