SEPARATOR FOR SEPARATING POLLUTIONS FROM LESS THAN THE LIQUID, ADVANTAGEOUS FOR PURIFYING OIL WATER

The object of the invention is a separator for separating the impurities suspended in liquids, particularly of a smaller weight than that of the Liquid, advantageous for cleaning oily wastewater, whose container expediently lengthened Oblong plan with a designated for the liquid to be cleaned, under the respective liquid level of the container arranged, fan-like

low investment and operating costs, alone or, as required, with other technological solutions Devices used in combination are * A disadvantageous property of the known settling devices - especially if the liquid to be cleaned is a contamination of greater specific gravity and contains one of a smaller weight, e.g. in the most common case of sand and oil contamination at the same time containing industrial wastewater - consists in the fact that in the devices mutually destructive Requirements should be met.

In the most widespread objects, in the various settling basins and separation tanks should namely on the one hand the wastewater can flow in laminar flow at the lowest speed to the floating Grains of sand settle at the bottom of the basin and the floating oil droplets rise towards the surface leave, while on the other hand there is generally the floating oil layer with one, hung in the basin Discharge or separating means is removed from the surface of the waste water, at least with the waste water should flow at such a rate that ensures the effectiveness of the separation. Apparently these two opposing requirements can not be satisfied at the same time, so that only one Compromise solution is possible.

Another fact that is devastating to the satisfaction of the above two requirements in practice in the fact that the wastewater load is by no means uniform over time, and its change is sudden. This jerky On the one hand, however, fluctuations disturb the developed or developing flow pattern, and on the other

on the other hand, wave phenomena, especially on the surface, but also in the depths, cause those that have already settled Granules stirring up with it, finally the level in the container is constantly changing, so that the trigger element c "once hanging freely in the air, once again in the air The liquid is immersed, i.e. does not carry out any deposition, or onto the element that is just on the surface impacting wave fills the drainage channel with water and destroys the efficiency of the separation or even that

1fO deposition foiled.

In order to eliminate the above problems, such a solution was made according to the Hungarian patent specification No. 169 472 elaborated, in which the separating device angeorndet on floating bodies and with at least one

] 5 row of nozzles is provided, while the cutting edge of the separating knife on or under the interface of the liquid to be cleaned and on its surface Contamination is set.

The only disadvantageous property of the known solution can be in terms of the "quality" of the deposited Contamination can be proven, namely it always contains a certain amount of the liquid to be cleaned. In practice, namely, the cutting edge of the separating knife cannot be precisely adjusted to the interface through However, the separating knife immersed in the liquid to be cleaned always brings water into the collecting channel with itself.

The purpose of the invention is to work out a solution with which perfectly "pure" those to be cleaned Liquid can only be separated in traces of impurities.

According to the invention, this object is thereby achieved

In our case, the separator housing 5 is completely open at the bottom, within the scope of protection can but it can also be designed in such a way that it has a base plate provided with at least one opening. Essential is only that the separator housing 5 and the interior of the container 1 are to be connected to one another.

In the interior of the separator housing 5 there is little

at least one exhaust pipe 6 installed, which in our The case is connected by a corrugated tube 7 to the drain port 8 provided for the contaminants. An adjusting ring 9 is pulled onto the thread at the mouth of the outlet pipe 6 shown in the drawing. gen · It should be mentioned, however, that the adjusting ring 9 is also mounted on the exhaust pipe 6 in a different way can be·

The rest, not shown in the drawing Elements of the complete device, as among others the inflow fitting, the drainage nozzle intended for the settling impurities of greater weight, are or can be according to the Hungarian patent specification no. 169 472, also the possibility of connection for complete technological cleaning road included

The operation of the device according to the invention will now be described.

The oil-contaminated industrial wastewater let into the container 1 flows in a laminar flow, while the oil floats on the surface and at the same time the impurities of greater weight settle down »·

The layer 11 of the impurity floating on the surface 10 of the liquid to be cleaned becomes with Help the gas flowing out of the nozzles 4, especially air, in a forced flow on the, under the surface 10 submerged separating knife 3 driven. The flow rate of the. liquid to be cleaned or the layer 11 are indicated by the arrows 12 and 13, respectively.

In the interests of trouble-free and perfect

IQ operation of the device should be the separator in such Way to be set that the separating knife 3 is immediately below the surface 10 of the to be cleaned Let liquid be, while the mouth of the outlet pipe 6 or the upper level of the adjusting ring 9 is above the However, the surface is below the surface 14 of the impurity that has already been separated out, which is formed in the separator housing 5 located

The essence and at the same time the greatest advantage of operating the solution according to the invention are that the, with the impurity located in the forced flow in the separator housing 5 introduced to cleaning liquid is separated from the contamination, so that in the drain port 8 exclusively "pure", the hu cleaning liquid contains at most traces of impurity.

The accuracy of the separation can therefore be achieved with the setting of the separating knife 3 on the one hand and on the other hand of the setting ring 9 can be specified or regulated in two stages.

Finally, a semi-operational test is described as an example, in which a tank with a 2.2 × 4.0 m floor plan of 2.2 × 4.0 m containing _{5 and 28 m of calm water}

Liter of heating oil of type TH 5/20 was poured. With the device according to the drawing, 28.5 liters of heating oil could be separated, while in the separator housing about 0.2 liters of heating oil remained on the surface of the water. The separated heating oil was burned in a household oil furnace, and no such irregularity was found
based on which the presence of water could be inferred.
