SUMMARY OF THE INVENTION The present invention relates to a liquid separation device consisting of a mixture of two different densities of liquid, for separating their components, especially for filtering oil from a water which is several times higher than its own, in particular for the surface of lined engineering facilities and adhering and / or adhering to the granules.

a) an open-surface canal or ditch receiving unit and a receiving unit for receiving a contaminated mixture, an intermediate compartment suitable for separating the mixture, and an outlet suitable for transmitting the purified liquid;

b) an additional filter unit having an olefinic and hydrophobic property located in the intermediate space of the receiving unit and comprising at least one filter insert and a filter box, preferably having a frame structure, including an additional filter unit.

Oil and fat-containing wastewater are produced in many areas of life. One of them is in the industry, such as crude oil production, oil transportation and processing, the metal industry, power generation (power plants), chemical plants, while the other part is created on the surface of open-air engineering facilities such as roadsides and bridges.

In both cases, oily wastewater requires environmental measures, because if they get unpurified into recipients, especially in the so-called living waters, then their purity will be severely damaged and will endanger the wildlife. Experience has shown that if such mixtures get into the groundwater, they can infect the soil in huge areas because of their high 'decay' and long decomposition times.

The dangers of wastewater emitted by the industrial industries were already in the 19th century. From the end of the 19th century onwards, various so-called separators were developed. Examples include US-A-745,519, US-A-925,834, US-A-995,521, and A-1,032,458, which have been around a hundred years ago, which have been able to retain a significant portion of the oil content of discharged waste water.

Progress in this area has been continuous since then, and the use of the difference in specificity of the two components of liquid mixtures has led to more and more perfect separators. These are disclosed in U.S. Patent Nos. 3,933,654, 4,132,645, US 4,422,931, US 4,938,878, US 4,980,070 and US 5,348,648.

Remarkably, the importance of oil-polluted waters in the vicinity of nature, especially the importance of oil removal of rainwater, was noticed until later. The XX. The concept developed in the 90s of the 20th century, which is described in HU 209 763. In principle, both industrial wastewater and line engineering facilities can be used. It is extremely advantageous that, unlike the previous ones, no mechanical equipment or human supervision is necessary, because it simply solves the separation with the proper geometric placement of the roller blades with high efficiency and unlimited lifetime. However, it has the disadvantage that it has to be equipped with specially designed pools, where separation takes place.

They operate on a different principle and are designed to separate oil from the surface of specially engineered engineering facilities and to separate the rainwater from the specific deposits that are suitable for catching oil, in particular oleophilic and hydrophobic minerals, or otherwise artificially produced mills, granules, cushions, and the like. contain filter layers.

Perlite has long been used as a filtering agent to remove the environmentally damaging component from dirty water from drainage ditches. Such a known solution is known from HU 216 261.

It exerts its cleansing effect by creating transverse nests in the drainage ditch of oil-contaminated rainwater, one or more of which can be fitted with perlite boxes, as required. The boxes have a hydrophobic perlite with a particle size of between 0.5 and 2.0 mm, designed to catch and filter the oil.

In practice, these perlite box filters have not been introduced. For several reasons. One is that the oil does not appear on the track surface of roads and bridges alone, but adheres to solid particles (such as dust, rubble, etc.). Therefore, he does not tend to be soaked up, but rather tends to settle down, and thus does not reach the perlite boxes.

The other and also unfavorable phenomenon is that in the case of a larger amount of rainwater, the decisive part of it passes through the perlite box (for example, it overcomes it). It also increases its inability to get stuck on the surface of the filter, and therefore it does not reach its interior.

The idea of reducing the oil content of rainwater draining off-road and also contaminated with oil was also considered in the description of the utility model U 2904 U. Interchangeable filter inserts are installed in the sinkholes installed next to this paving. The mines have oleophilic and hydrophobic filter cartridges, and the water that passes through them continues in drainage ditches. Since a large number of mines are needed, the economics of cleaning are debatable.

It is an object of the present invention to provide an environmentally friendly and economical separation of the oil content of mainly rainwater engineering facilities such as roads, bridges and oil or oil-contaminated rainwater. It is also an object of the present invention to provide prefabricated receiving objects based on the structure of the apparatus.

It can also be associated with existing ones, such as unleaded perlite oil traps.

The idea of the invention is based on the recognition that if structurally different filter boxes are placed from the line engineering facility to the drainage water drainage channel or ditch, and the material used to coagulate the oil droplets as a filter insert and thereby to float in addition to the settling and floating contaminants. it can do the job.

It is furthermore appreciated that the filter boxes and the receiving units are suitable for reducing the flow rate of the contaminated water and thus increasing the passage time thereof. This improves the conditions for soiling the polluting oil.

In accordance with the object of the present invention, the liquid separator according to the invention generally comprises a mixture of liquids of different densities to separate their constituents, in particular by filtering off oil from a quantity of water which is several times higher than its own, in particular on the surface of linear engineering facilities and adhering and / or adhering to the particles in a solid state. :

a) an open-surface canal or ditch receiving unit and a receiving unit for receiving a contaminated mixture, an intermediate compartment suitable for separating the mixture and a discharge side for the purified liquid;

b) an additional filter unit having an olefinic and hydrophobic property located in the intermediate space of the receiving unit and comprising at least one filter insert and a filter box, preferably having a frame structure, including an additional filter unit, such that

(c) a removable boundary plate in front of the filter box on the receiving side of the receiving unit is installed;

d) a dip wall and / or a tilting wall is located on the discharge side of the apparatus on the filter side.

A further feature of the liquid separator according to the invention may be that the receiving unit is an existing monolithic reinforced concrete structure having an intermediate space suitable for implanting the filter box. There is one or more additional filter units in the intermediate space of the reinforced concrete monolith receiving unit. The one or more additional filter units are located in the filter box with respect to the fluidity of the liquid mixture and the filter box in the monolith receiving unit.

In another embodiment, the receiving unit has a prefabricated reinforced concrete structure workpiece having a mounting wall for assisting with installation, such as transport hooks, an intermediate space for the insertion of the filter box, and preferably a drainage side suitable for cleaned water.

There is one or more additional filter units in the intermediate space of the prefabricated reinforced concrete receiving unit. The additional filter unit is positioned in the filter box with respect to the fluidity of the liquid mixture and the filter box in the intermediate space of the prefabricated receiving unit. On the output side of the prefabricated reinforced concrete receiving unit, a secondary wall is optionally provided.

The liquid separator according to the invention has a number of advantageous properties compared to the prior art structures of the prior art. One part of the benefits is technical, and the other part is of an economic nature and can be clearly demonstrated both in the case of the prefabricated assembly unit and in the rebuilding of existing monolithic objects such as perlite oil pliers.

The experiments prove that the benefits can be traced back to the structure without exception. Most importantly, the so-called secondary wall, which is part of the prefabricated receiving unit and the filter box in the case of an existing monolithic workpiece, causes swelling on the incoming side of the device. This swelling has several consequences and each is favorable.

On the one hand, it is beneficial to have a natural sedimentation so that the sludge containing a significant part of the dirt is deposited in advance. The retained sludge can be easily and easily removed, the capacity and efficiency of the equipment are high, and it is capable of catching the rolled sediment besides floating and floating dirt. It is also a favorable feature that the equipment can be installed and relocated very easily and quickly. Another advantage is that it works unattended, reliably, weather-insensitive and so-called coalescence filter inserts, and its cleaning every six months is sufficient.

Among the economic benefits of the equipment, it is worth noting that its investment cost is significantly lower than the other known solutions, it does not require complicated construction technology, special delivery conditions. It is also a good thing that a minimal amount of earthwork and a relatively low-load lifting machine are sufficient for the installation, and it is also suitable for the low-cost and continuous implementation of oil removal without any structural changes.

Figure 26: Side view of the filter box.

In Figure 1, the filter box 105 is shown from the receiving side 104g of the prefabricated reinforced concrete unit 104g, inserted in the intermediate space 104a. The filter box 105 is provided with the front boundary tabs 101 to be gripped by the lifting handles 101a and the additional filter units 102 that can be gripped by the lifting handles 102a. The receiving unit 104 can be prepared either in the concrete factory or near the line engineering facility by pre-production on site. A105 filter box can be inserted into the channel 104e along the longitudinal walls 104b in the channel or ditch alongside the line facility to be retracted to any desired location. The filter box 105 lies at the bottom of the intermediate space 104c 104a.

Figure 2 shows the same receiving unit 104 in the outlet side view 104h. From this direction, an additional filter unit 102 between the support pins 104f and the filter box 105 is visible, as well as the wall 104d through which the water passed through the receiving unit 104 leaves the receiving unit. The tumble 104d is suitable for further cleaning the wastewater already desalinated by the filter box 105 in a further step.

Figure 3 shows the front delimiter 101, the main parts of which are the support frame 101b and the cover plates 101c. The upper part of the support frame 101b is provided with a lifting handle 101a suitable for moving the entire front panel 101. The same is shown in a larger scale front view in FIG. In both, it can be clearly seen that the cover plate 101c is a set of parallel strips which, relative to each other, displaces the support frame 101b relative to one another on the front and back sides of the frame 101b.

In Figure 6 again, in the axonometric view, the additional filter unit 102 is shown with the cassette body 102d, the support cords 102c secured between its longitudinal edges and the lifting handle 102a. The additional filter unit 102 is shown in a larger front view in FIG. 7, in a horizontal sectional view, in FIG. 8, and in a vertical section in FIG.

In the figures shown so far in the auxiliary filter unit 102, the filter insert is not markedly secured on both sides of the cartridge body 102d. On one side, the cassette body 102d has a fixedly reinforced support beam 102c, while on the other side a removable clamping grid 102b is held in position. The clamping grid 102b can also be formed by welding with the best possible cross steels. This is shown in Figure 10.

The filter box 105 without the receiving unit 104, but with the front bounding plate 101 and the additional filter unit 102, can be seen in FIG. 11 from the outlet side 105n in FIG. As shown in Figures 1 and 2, in the present embodiment, the apparatus is composed of two halves in which two filter boxes 105 are each individually spaced with a front delimiter 101 and an additional filter unit 102.

The filter housings 105 have a horizontal sectional view of the outlet side 104 of the receiving unit 104 in FIG. The support body 105 of the filter box 105 is a self-supporting frame 105a, with two end members 105b, and a 105h gate under the 105b immersion wall.

Drainage water to be de-oiled comes from and through the front delimiter 101 into the filter box 105. The front panel 101 itself does not have a filter role, but its presence is important in several respects. It performs energy breakdown, frost protection and shading. The latter means protecting the filter material against UV radiation.

Water slowing down on the front delimiter 101 passes through the filter cartridge 103, which, by its oleophilic and hydrophobic properties, can "float" micro-oil droplets. They gradually coagulate into larger droplets and enter the 105g supernatant after the filter cartridge 103.

The 105h passageway below the dip wall 105b extending from the top to the 105g upstream space is continued by the clearing water, from which the bumping opening 105i above the sloping wall 105c moves into the swing space 105j. The water then flows to the secondary filter unit 102.

The additional filter unit 102 may be "empty" as shown in FIG. 15, or may be shown in FIG.

Lake 227 299 Β1 with filter cartridge 103a. The latter embodiment is suitable for further improvement of cleaning efficiency. The filtering element 103a is supported by the support sticks 102c from the front side of the purge of the purifying water, while the back side includes the clamping grid 102b.

In larger scale Figure 16, it can also be judged that the position of the filter insert 103 of the filter box 105 is determined by the support sticks 105f, and that the water leaving the optional additional filter unit 102 is discharged from the filter box 105 through the outlet port 105k under the final 105b wall.

Fig. 17 shows the 105d shell shell forming the end walls parallel to the direction of the water flow. In contact with the shell skin 105d a

105 is a filter box with longitudinal walls 104b for defining intermediate space 104a of receiving unit 104. Fig. 17 shows the control tabs 105e for assisting in positioning and removing the filter housings 104 in the receiving unit 104.

In another possible embodiment of the liquid separator according to the invention, it is not necessary to make prefabricated units 104, but instead they can be made of monolithic reinforced concrete.

106 existing artworks. For example, those that were previously part of the so-called "perlite oil pliers". An example of this is shown in Figures 18 and 19.

Referring to FIG. 18, the receiving unit 106 as an existing artwork and the filter box 105 contained therein can be viewed in the axonometric view of the inlet side 106d of the water flow, while viewed from the direction of the outlet side 106e. Since the receiving unit 106 was not originally provided with the outflow wall 104d referred to in the above example, it is then positioned in the intermediate space 106a, which is mounted on the bottom 106c.

105 filter boxes should be supplemented with an additional 105c (secondary) tilt wall.

The size of the filter box 105 is aligned with that of the

106 for cross-sectional forming of the inlet side 106d and the outlet side 106e of the existing artwork. The water to be cleaned flows from the incoming side 106d to the filter box 105 and leaves it to the discharge side 106e.

Existing works of art 106 are generally included in the "perlite box filters", and, as we have seen earlier, are unable to create a backflow on the incoming page, and thus provide effective screening from them. However, according to our idea, the outlet sides 106e are not only suitable for receiving the perlite box to be abandoned, but also for replacing but much more efficient filter box 105.

Figures 18 and 19 show that a

105, the filter box 105 is also in contact with the front delimiter 101 and the additional filter unit 102. This is confirmed by Figures 20 and 21, where the existing monolith

Filter boxes 105 were displayed without receiving unit 106.

The filter box 105 forming the "soul" of the apparatus is now assembled from two half-boxes, the vertical section of the discharge side view of Figure 22, the vertical section of Fig. 23, is shown in Fig. 24, and a more detailed drawing thereof is shown in Fig. 25, while FIG. a side view of the filter box is shown in Figure 26.

The arrangement, the manner of incorporation into the existing monolith 106 receiving unit, and the operation of the apparatus itself are the same as the first embodiment. There is no difference in the material of the filter cartridge used, nor is it possible to place one or two layers in the water to be cleaned. Experience has shown that there is no significant difference in the density of filter regeneration over time.

The liquid separator according to the invention is primarily intended for installation on line engineering facilities, namely roads, railway tracks and bridges, to remove hydrocarbon impurities, but also suitable for use in drainage systems for pools, sedimentation ponds and reservoirs, so as to retain any dirt capable of escaping.

Its importance lies first and foremost in its structural design, ease, speed, ease of deployment and removability, as well as in its investment and maintenance performance.
