Description

one

The invention relates to devices for the purification of water contaminated with petroleum products, and can be used for the purification of marine water and ballast waters polluted with petroleum products.

A device for multistage purification of oily water is known, including a transfer pump, nozzles for supplying and discharging treated and purified water, a chamber with coalescing elements and oil collectors 1.

However, the imperfect construction of the flow part and, as a result, the low reliability and efficiency of the working elements do not provide an adequate service life of the device and a satisfactory degree of wastewater treatment.

The closest in technical essence and the achieved result to the proposed invention is a device for purifying water from oil, comprising a housing, pipes for supplying purified and discharging purified water, a cylindrical chamber for collecting purified water and a coalescing element with a coalescing material 2. .

The disadvantage of such a device is the low degree of water purification, since in it the coalescing element is quickly filled with oil products.

The purpose of the invention is to increase the degree of water purification.

This is achieved by the fact that the device is equipped with an after-treatment chamber filled with an adsorbent of petroleum products, the coalescing element is designed as a perforated cup with a socket, while the co-scoping material is located on the outside of the cup.

FIG. 1 and the proposed device, a longitudinal section along its axis; in fig. 2 - the same general view.

Claims (2)

The device contains a vertical housing 1 with a lid 2, a diaphragm 3 and a partition 4 with a bottom 5. The device is divided into a rough cavity 6, a fine cleaning cavity 7 and an after-treatment chamber 8. In the diaphragm 3, pipes 9 are welded in, 10 where, with the power of pushing sleeves 11, the coalescing elements 12 are covered and sealed, covered with nonwoven plipropylene material deposited on the perforated cup 13. The pre-treatment chamber 8 is filled with an adsorbent 14 of oil products and is closed on top with a mesh cover 15. In case 1 discreet patrub .ki 16 and 17 for filling and removing the adsorbent. On the axis of the housing 1 from the bottom bottom 18 to the diaphragm 3, a pipe 19 for supplying purified water is installed with a housing 20 forming a steam jacket 21 for heating the purified water. A diaphragm 22 is installed in the lid 2 of the device, separating the oil-collecting cavity 23. On the housing 1 there is a welder 24 for supplying the water to be purified, a welder 25 for draining the purified water, a privet 26 and 27 for draining oil debris, a fitting 28 for steam, condensate test taps 30, water-indicating glass 31, pressure gauge 32, thermometer 33, drain plug 34. The device works as follows. Water polluted with oil products is supplied by a pump (not shown in the drawings) to a steam-heated pipe 1 Through the slits in the upper part of the pipe, water enters the settling cavity 6 of rough cleaning. The operation of this band is based on the principle of gravity sediment. The separated oil particles from the bottom are collected in the upper part of the settling cavity. Finely dispersed particles of petroleum products, not released by gravity, are lowered with water flow into the lower part of cavity B and through pipes 9 flow to the outer surface of the coalescing elements 12. When passing through 04 elements 12, petroleum particles are enlarged and float in the thin cavity 7 cleaning, pass through the central hole of the diaphragm 22, collecting in the oil collecting cavity 23 of the fine cleaning stage. The last two-stage purification water is directed to the post-treatment chamber 8, where, having passed through the active adsorbent 14 of oil products, it undergoes the final stage of purification and drains overboard through pipe 17. When petroleum products accumulate in the oil and gas collecting cavities, they are removed through primers 26 and 27. The level of oil residues is monitored by water-indicating glasses 31 and through taps 30. The claims of the device for cleaning water from oil products, including a pipe body, supply purified and discharged purified water, a cylindrical chamber, collecting purified water and a coalescing element with a coalescing Material, characterized in that, in order to increase the degree of purification, it is equipped with purification With the oil filled with an adsorbent of petroleum products, the coalescing element is designed as a perforated cup with a socket, while the coalescing material is located on the outside of the cup.
