Description

The technical field to which the utility model relates.

The utility model relates to the field of ecology, in particular, to the field of elimination of technogenic environmental pollution and can be used to purify water (industrial and waste) from oil products at enterprises for the transportation, sale and use of oil products. The compact utility model allows you to quickly and efficiently collect oil products from the water surface due to the presence of a cavity in the device between the filter element and the suction hole of the nozzle, as well as an oil-repellent hydrophobic multilayer sorbent element placed on a metal mesh that protects the filter element from “dropping” into the nozzle outlet. The utility model can also be used to collect oil products from the ground.

State of the art

Known vacuum oil gathering device company "ECOservice-NEFTEGAS", manufactured according to TU 8026-041-40443658-2007 and designed to collect spilled oil and oil products, as well as other pollutants from the water surface and from the soil surface, consisting of a vacuum pump with driven by an internal combustion engine, a removable vacuum dome, a hopper with a discharge nozzle and a suction nozzle. The device is compact, light in weight, it can be effectively used in hard-to-reach places where heavy equipment cannot be delivered (1. Equipment for localization and liquidation of oil spills // EKOservice-NEFTEGAZ LLC. Promotional brochure.- M .: 2009).

The disadvantage of the technical solution is that the device simultaneously collects a mixture of water and oil and, in the future, requires additional expensive operation to separate them.

A known method of cleaning the surface of the water from oil and oil products using a sorbent containing fibrous cellulosic material (textile waste, technical wool and others), treated with oxidized atactic polypropylene (2. Sirotkina E.E., Safonov G.A., Bembel V. M. Boltrukevich EP Patent of the Russian Federation No. 2061541 C1, publ. 06/10/1996).

The disadvantages of the method:

- limited scope (the method is intended to remove oil only from the surface of the water);

- the need for additional technological operations for the introduction of polypropylene in the structure of the cellulosic material.

A known method of purifying water from oil and oil products, in which the water is treated with a hydrophobic sorbent - a product of grinding cellulose-containing material - waste laminated with a polyolefin film of paper, cardboard or a mixture thereof in air in a hammer mill. The grinding product has a fractional composition, wt.%: Fine fraction with a size of 0.5-0.9 mm - 20-30; a large fraction of 1.0-2.0 mm in size - 70-80. The specified treatment is carried out in a vessel with double perforated walls at a density of filling the inter-wall space with a sorbent 0.03-0.06 g / cm ³ . Then the water is filtered through a porous sheet material with a density of 150-500 g / m ² formed from the specified product of grinding waste from laminated paper, cardboard or a mixture thereof. The method allows to increase the degree of purification from oil and oil products to 98% (3. Akhmedov Artyk, Galkina L.A., Osipov P.S., Efimov SB, Gushchin A.E. A method for purifying water from oil and oil products. Patent RF №2201898, publ. 04/10/2003).

The disadvantage of the invention is the multi-stage purification of man-made water.

There is a two-stage method for water purification using a carbon sorbent at each stage: granular activated carbon at the first stage, microporous carbon fabric at the second stage (4. Agrest M.M., Gomolitsky V.N., Lavrov V.V., Reifman L .S, Chechevichkin V.N., Pavlenko I.V., Yurkevich A.A., Medvedev S.L., Kartel N.T., Strelko V.V., Litvinskaya V.V., Benediktov A.P. Sorption filter, USSR Patent No. 1567243 A1, publ. 05/30/1990). The disadvantage of using sorbents based on coal is a quick loss of efficiency due to the "clogging" of active centers, the allocation of fine fractions and organic impurities in water, as well as high cost (prototype).

The objective of the utility model is to create a portable device for collecting technogenic water, which allows one step to quickly and efficiently collect oil products from the water surface with the simultaneous separation of water from oil products.

The essential features that characterize the utility model

Restrictive: collection and purification of technogenic water sorbent.

Distinctive: a device for collecting and treating man-made water with an oil-repellent hydrophobic multilayer sorbent element - a filter (hereinafter referred to as a filter), which is a multilayer plate fixed on a metal grid, having a cavity between the grid and the suction nozzle opening that serves to prevent “clogging” of the suction nozzle with a sorbent that allows to separate man-made water into water and oil components.

Utility Model Disclosure

This goal is achieved in that a device with an oil-repellent hydrophobic multilayer sorbent filter of a thermoplastic material in which oil is adsorbed is installed on a site contaminated with oil products. Due to the hydrophobic properties of the sorbent, water passes through the filter and enters a separate drive.

The technical result achieved in solving this problem is to accelerate the purification of oil-contaminated water through an oil-repellent, hydrophobic sorbing filter.

Brief Description of the Drawing

In FIG. 1 shows a General view of the device. The device consists of an oil-repellent hydrophobic multilayer sorbent (filtering) element 2, which is a multilayer plate located on a metal mesh 3, a suction nozzle 5 with a pipe 7, body 4; cavity 6; drive 8 with inlet and outlet nozzles 9, a vacuum pump (or vacuum cleaner); float 10. A feature of the device is that between the element 2, mounted on a metal mesh 3, and the upper part of the housing 4 there is an empty space in which when the pump is operating, a pressure is created below atmospheric. In addition, the metal mesh 3 rigidly fixed in the housing does not allow the sorbing element to “sink” into the opening of the suction nozzle 5.

Utility Model Implementation

The filter can be made of any petrophilic hydrophobic sorbing thermoplastic material, for example, from the material "Ecosorb" (TU 8397-230-00302327-01). The Ecosorb oil sorbent, manufactured by industry in the form of a non-woven fabric of large overall dimensions, is made by needle-punched method from polypropylene fibers. The oil capacity is 18-28 kg / kg, density 40 kg / m ³ (web density 0.3 kg / m ² ). A positive feature of Ecosorb is the possibility of repeated use after extraction in special devices.

The device operates as follows:

A device with an oil-repellent hydrophobic multilayer sorbent element 2 is installed on the water surface polluted with oil products 1, connected to the pump (vacuum cleaner) by means of a suction nozzle 5 through the accumulator 8. When the pump is turned on, the influx of the mixture of water and oil products into the sorbent is intensified. Water passes through the sorbent and enters the reservoir 7. After the sorbent is saturated with oil, the pump is turned off, the sorbent is squeezed out and can then be used repeatedly.

Using the utility model allows to reduce the cost of purifying man-made water from oil products by eliminating the additional operation of separating the fractions of water and oil products.

The device is simple in design, compact and able to clean large volumes of water efficiently without frequent replacement of the filtering sorbent element.
