SU1022018A1 - Instrument for determination of oil and petroleum product concentration in water - Google Patents

Description

The invention relates to the analysis of liquid media, in particular, devices for determining the concentration of petroleum and petroleum products in shipable waters (vessels, bilge, wash and bulk) and can be used in various industries of the chemical, oil refining, paint and varnish industry and so on. d.

Known photometric analyzer Donets, which is based on the method of oil extraction using OCU4 with photometric measurement in the infrared region of the spectrum. A sample preparation device (epemening and mixing), a cuvette, a radiation source, an infrared analyzer and a measuring device. The disadvantages of this device are that the measurement process lasts more than 10 minutes, each test requires a new batch of clean, spent CCfc to lower the weight. ; the device, while the device is manual, requires a ch & a.vir alista for the ana: yiz.

The closest to the solution to the vaobreubaus is a device for determining the concentration of oil and oil products in water, containing plaster, solvent and sample dispensers, a mixer equipped with an engine, a device for mixing water with a solvent, a device for separating water and a solvent, an infrared analyzer , regenerator and measuring device. The process of prb preparation takes place in three independent units - a mixer and in two 4 units. The mixer is made in the form of an airtight container, inside of which is placed a mixer with a disc of material. Outside the tank, a magnet mounted on the drive axis

The first filter is made in the form of dicks with a filter element placed between them and an additional lance, while the contact surfaces with the filter element are made in the form of an annular grooves. Heating elements together with thermostatic elements are intended for thermal compensation of the filtering solution (mixture of water and solvent.). There are also inlet and outlet fittings, an overflow tube, and fasteners.

The second filter is intended for additional and complete separation of water from the solvent and consists of an upper and lower glasses with a filtering element placed between them, an apavayu switch with a heating system, inlet and outlet pipes, control rings, cap gaps, etc.

After the water is separated from the solvent with oil, the latter enters an infrared analyzer, the signature of which is proportional to the oil content 12.

The disadvantages of the device include the presence of three self-contained sample preparation sites, a hydraulic chain between them, a fastening system, which strengthens its design, reduces reliability, and increases the path of movement of the mixture under study.

The aim of the invention is to simplify

construction and acceleration of the measurement process.

Postavpein's goal is achieved by the fact that in a device for determining in water, the concentration of oil in petroleum products containing a filter, connected through a solvent dispenser in samples with a mixture, a submersible filter, and a connected device with a water meter from water dissolve, and the pressure is connected to An infrared 1m analyzer with a torus that is soy: mixed with a dissolver dispenser, {jugerdtor and measuring svvrrr, mixing device and the device dp separating water from the solvent are made as a two-in outer - moving bowls, coaxially fixed on the motor axis. A heat pipe, each of which is located ib respectively in the outermost immobile thicket, with the outer movable bowl made of porous material, and the mobile is movable in the fixed bowl with through holes through the entire surface, above internal feed bowl installed with; Mainly with the engine, a cylinder with two holes in the upper part of the lateral surface connected to the dispensers {dissolve and samples, and in the lower part of the hole for npo & i, there is a screw inside the hollow cylinder on the engine, under the external movable bowl fixed external more often fixed pornographic partition.

On flash G presents the schematic diagram of the device; Wah FIG. 2 is a schematic of the sample mixer in dissolving the mouthpiece of separating the water from the solvent.

The device consists of taking filter 1 for cleaning from all sorts of mechanical impurities, metering pumps 2 and 3, corresponding to the dp of the test water-and-oil mixture in the four-porous uperod, a mixture of 4 sample and solvent, a 5 dp unit of water from the solvent, an infrared analyzer 6 with a sample and a solvent, a 5 dp unit of water from the solvent, an infrared analyzer 6 with two tubes, and a 5 dp unit of water and solvent from the solvent, an infrared analyzer 6 with a sample and a solvent, a 5 dp unit of water from the solvent, an infrared analyzer 6 with a sample and a solvent; and working, regenerator 7 (cleaning the SS from oil). n vtermite the device 8. Mix the sample and solvent inlet and the device for separating water from working (fig. 2) consists of an external non-cup bowl 9, which is catfish, and the inner fixed bowl J.O, icoaxcitaRbEO established relative to КР1Чус а. The enclosure is sealed with Kj2 imXicjofl.:. . In the mornings of bowls 9 and 10. there are located 12 bowls of 12 (internal) and 13 (lids), more so on the dvigatein axis 14. Under the bowl 13 there is a separate bowl 15, fixed by the holder 16. A wave is fixed above the moving 12. cylinder 17, inside of which a screw auger 18 is located on the engine 14 axis. B1) Parts of the side surface of the nonofo cylinder have two openings 10 and 2O for injection of liquid 2 and 3 for injection and solubilizing pumps 2 and 3, and In a quay part of the side surface of the cypivor, there are 21 holes of the output mulgirovannoy sample. The movable bowl 12 is provided with a hole diameter of 0.5-1 mm. The movable bowl 13 is made of a porous fluoroplast 1-3 mm thick with a porosity coefficient of 20-40% and a pore diameter of 15-8 microns. The device works as follows. Investigated water with oil enters through the PTR device 1 into the dosing device 2, at the same time the solvent (pure four carbon carbon SS) is supplied to the Node 4.5 with the same dosage device 3. The mixture of water and oil and solvent through the holes 19 and 20 respectively enter the hollow cylinder 17. When the engine 14 is turned on, 1 84 turns the screw auger 18 and the bowl 12 and 13. The mixture in the cylinder cavity is stirred and through holes 21 are dropped into the bowl 12 Then, through the holes in the bowl 12, the mixture enters the gap formed by the movable bowl 12 and the stationary bowl 10, additionally mixes and drains onto the rotating bowl 13. The liquid mixture is intensively mixed, filtered, the solvent with oil seeps out onto the surface porous septum 15, and the water under the action of centrifugal force rises along the inner surface of the bowl 13 and is discharged into the cavity formed by the body 9 and the vorotoobrazny holder 16. Next, the solvent L comes to the oil analyzer 6, the regenerator 7, and from there the pure solvent enters analyzer 6. The magnitude of the signal is proportional to the concentration of oil in water, from the infrared analyzer enters the measuring device 8.. The process of preparing the sample for analysis in a known device is carried out in three independent nodes, connected by a complex hydraulic chain and having a complex system of connecting and sealed elements. The technology of making uzps is quite resilient, requires the use of expensive, such as titanium, or special materials that are not produced by the domestic industry. In the proposed invention, the process of preparing a sample for analysis is carried out in one node, which will improve the reliability, simplify the design of the instrument , reduce the capacity of the separation process solution 1tel from water, reduce the intensity of metal, use domestic materials (porous fluoroplastic). Monitoring the degree of contamination by oil and its products from waters discharged from vessels will ensure the preservation of fauna, improve the sanitary conditions of life of the population, and will reduce the amount of foreign currency fine for discharging bilge, ballast and polluted waters into territorial waters.
