Description

Description of the invention

The useful model belongs to installations for degassing and drying of liquid oils and can be used 2 for high-quality processing of transformer oil.

The well-known degasser for processing transformer oil according to the author's certificate Mo1640846, cl.

VO1019/00, publ. 04/07/1991 composed of a hermetic chamber, which is supplied with a nozzle for connecting the vacuum system, a suction nozzle (nozzle) for supplying raw oil for processing and a nozzle for removing processed oil.

Inside the chamber there is a flow converter in the form of a nozzle and an obstacle in the form of a truncated cone, the large base of which is open and facing the nozzle, and the smaller base is closed by the bottom.

The flow converter is located along the axis of the chamber, the height of which is less than its diameter.

The disadvantage of the known device is the lack of foam crushing, which is formed in large quantities, that is, the oil jet foams the entire volume of the chamber and a large layer of foam makes it difficult for gas to escape from the oil. 12 The famous vacuum liquid degasser according to the certificate of the Russian Federation for the utility model Mo14527, class.

VO1019/00, publ. 10.08.2000, contains a cylindrical case with a lid, in which a package of conical plates, located coaxially with a cone upwards with a gap between them, is installed, on the conical surfaces of which carbonated liquid is supplied through a central vertical loaded pipe, while the plates stand back from the walls of the case and are fixed to each other vertical perforated pipes that serve to remove the removed gas from the case. The inlet pipe for the liquid is connected to the loaded pipe, and the drain chamber for the degassed liquid has a system of taps.

The disadvantage of the known degasser is the possible skewing of the package of conical plates with the displacement of the central annular holes in the plates relative to the loaded pipe and as a result incomplete exit from the liquid of the gas that accumulates in the upper part of the housing cover. 29 The well-known liquid oil degasser according to the patent of the Russian Federation Mo2156638, cl. VO1019/00, publ. sv) 27.09.2000 contains a vacuumed metal case, the upper part of which has an outlet for processed oil, and the lower part has an outlet for purified oil.

The housing is supplied with a cylinder-shaped oil supply tank.

In the upper base of the tank, there is a treated oil supply unit, which is made with the possibility of injecting an oil stream tangentially to the inner surface of the tank, while the oil flow splitter o is fixed in the housing at the level or below the base of the tank, maintaining a gap between its edges and the walls of the housing. with

The processed oil supply node is made in the form of a nozzle, the inlet end of which is rigidly fixed in the upper base of the oil receiving tank.

The disadvantage of the known device is the accumulation of gas in the upper part of the case, while the effect of oil degassing is reduced.

The famous liquid degasser according to the patent of the Russian Federation Мо2 139 120, cl. VO1O 19/00, publ. 10.10.1999 "contains a metal body with two jet-forming devices (elements) located in it, which are equipped with central conical channels and are installed on one and the other side of the common central 70 axis of the body with inlet and outlet nozzles for liquid and outlet nozzle for gas, while the collector is distributed connected to the cavitation chamber, which is created by the end parts

From" jet-forming devices that are directed towards.

We take this construction as the closest analogue.

According to the prototype, the liquid degasser contains a metal body with inlet and outlet nozzles and jet-forming elements for receiving oil from the distribution manifold, and with an outlet nozzle for gas. The disadvantages of the closest analogue are the complexity of the design, the inefficiency of its operation, and during the first pass, the liquid, for example, oil, is not sufficiently degassed, and it is difficult to regulate the supply of oil and its output.

Ta" 20 The useful model is based on the task of developing a liquid degasser that provides effective treatment of highly viscous liquid, for example, transformer oil due to jet-forming elements, which are sprinklers in the form of tubes with holes that are placed inside the closed internal cavities of A cylindrical filters, which represent brown filters, along the perimeter of which there is porous corrugated paper, where the saturated foam of oil is evenly distributed over

So" the entire surface of the filter paper with additional foaming and crushing of the oil, the jet of which flies out through the holes in the sprinkler tubes under pressure and is thrown onto the surface of the corrugated filter paper in the form of foam or bubbles, which intensively removes air and degasses the oil.

The solution to the given problem is provided by a liquid degasser, mainly transformer oil, which contains a metal case with inlet and outlet nozzles and with jet-forming elements for 60 reception of oil from the distribution manifold, and with a gas outlet nozzle, due to the fact that jet-forming nozzles are installed in the upper part of the casing the elements are sprinklers in the form of tubes with holes, which are directly connected to the distribution manifold and installed horizontally in the center of the closed internal cavity A of cylindrical filters, along the perimeter of which filter paper is located, while the filters are hermetically fixed between the end flanges, which, in turn, , installed on both ends of sprinkler tubes with the possibility of their dismantling for removal or replacement of used filters.

In order to evenly distribute the ejected jet of oil over the entire surface of the filter paper and crush the created oil foam and absorb it through the filters, they are a flake filter, which is made of porous corrugated paper.

For better oil intake, sprinklers in the form of tubes with holes are installed along the axis of the fuel filters, and one end of the sprinkler tube is connected to a distributed collector, and removable plugs are installed on the other ends of the sprinkler tubes for periodic cleaning of the tubes and the collector.

For tightness, a seal is located in the grooves of the end flanges, and a rubber gasket is installed between the fuel filters. 70 A safety valve is installed in the upper part of the housing, which is activated when the oil level in the housing increases. To prevent impurities from getting into the housing, the inlet pipe is connected to the oil filter, which is installed near the housing. To prevent oil from entering the vacuum pump (not shown), the end of the gas outlet pipe is connected to an oil collector, which is installed close to the housing.

The technical result achieved when using a useful model: - improved operation of the degasser, because the spray tubes are evenly filled with oil from the distribution manifold, while the oil is sprayed through the holes in the tubes under pressure in the form of a jet, which turns into foam and spray and is evenly distributed on the entire inner surface of the fuel filters, which are made of porous corrugated paper, everywhere the pores of which produce foam and splashes with the extraction of gas; - effective and high-quality oil treatment is achieved due to foaming of oil on the surface of the filter paper as a result of the different value of the vacuum in the closed inner cavity A of the cylindrical filters and the vacuum in the degasser body; in the proposed fuel filters, the foam is crushed and harvested through a layer of corrugated paper, thereby water and gas are removed from the oil film in the form of foam and bubbles; - dosed selection of the number of holes in the sprinkler tubes ensures the formation of foam and its distribution over the entire surface of the fuel filter paper, and the different level of vacuum in the closed cavity A of the filters in relation to the vacuum in the degasser body ensures the output of foam and splash on the outer surface of the filters, which increases the area of gas extraction from the thin film of foam and bubbles and improves the quality characteristics of the oil; - monitoring of the oil level in the degasser is ensured due to a non-contact pointer with a signal at the time of tip and tah oil levels; "g zo - the presence of air-closed cavities during oil pumping from the degasser is excluded due to the installation of an oil pump vertically under the degasser. co

According to a useful model, the liquid degasser, preferably transformer oil, contains a metal body 1, which is under a complete vacuum and is connected to a vacuum gauge 2 (see Fig. 1, Fig. 2). In the upper part. body 1, there are jet-forming elements, which are sprinklers in the form of metal tubes C with holes 4, which are placed in a metered manner, while the tubes C serve to receive oil from the distribution manifold 5, which is connected to the inlet pipe 6 (see Fig. 2, Fig. 3, Fig. 4).

An oil filter 7 is installed near the housing 1, through which the oil enters the inlet pipe 6

Ge) and then to collector 5 (see Fig. 2).

The sprinkler tubes 3 are installed horizontally in relation to the distribution manifold 5 and parallel to each other, while only one end of the sprinkler tube is connected to the distributed

Go! collector 5 (see Fig. 4, Fig. b).

Tubes C of the sprinklers are installed horizontally in the center of the closed inner cavity A of the fire sprinklers

T" filters 8, which are hermetically fixed to the end flanges 9, which, in turn, are installed on the ends of the tubes

Of sprinklers and have seals 10 (see Fig. 4, Fig. b). Between the end flanges 9 on the tubes C, it is possible to install two or more fuel filters 8, between which there is a rubber gasket 11 (see Fig. 4).

Along the perimeter of cylindrical filters 8 is porous corrugated paper with the formation of a closed

Han of the internal cavity A in the filters, along the axis of which the sprinkler tubes C are installed (see Fig. 4, Fig. 5, Fig. b).

Removable plugs 12 are installed on the second ends of the sprinkler tubes C for periodic cleaning of the tubes C and the collector 5, and the end flanges 9 on the tubes C can be dismantled to remove or change the used filters 8 (see Fig. 2, Fig. 4).

The gas outlet 13 is connected to the oil collector 14, which is installed near the housing 1 of the vacuum pump (not shown) (see Fig. 1, Fig. 2).

The oil level is monitored through the oil gauge glass 15, which is mounted in the porthole 16 of the housing 1 (see Fig.

Fig. 2).

The safety valve 17 is mounted in the upper part of the housing and serves to close the flow of oil to the vacuum pump (not shown) with an excessive increase in the level of oil in the degasser, which can be seen through b bKlo 15.

The housing 1 of the degasser is mounted on the racks 18, and the vertically located oil pump (oil pump) 19, which has a pressure gauge 20, is attached to the bottom of the housing (see Fig. 1, Fig. 2).

Through the nozzle 21 of the oil pump 19, the drained and treated oil is discharged from the degasser body 1 to the consumer.

Ball valves 22, which are reliable during operation, are installed at the oil inlet of the oil pump 7, at the oil collector 14, and at the oil outlet at the nozzle 21 of the oil pump.

On the housing 1 of the degasser, a thermal alarm 23 and a non-contact arrow pointer 24 are installed with a signal at the time of tip and tah levels of oil in the degasser.

The control panel panel 25 and lighting devices 26 70 are mounted on the body 1 of the degasser (see Fig. 1, Fig. 2, Fig. 3).

Oil degassing in the degasser is carried out as follows:

The supply (suction) of transformer oil to the distributed collector 5 in the housing 1 is carried out due to the vacuum in the degasser.

The transformer oil under pressure is supplied to the tubes C of the sprinklers, from which the jet of oil exits /5 through the metering holes 4 in the tubes Z and is evenly sprayed over the entire inner surface of the corrugated paper of the fuel filters 8, and then the jet of oil is broken up, foaming the oil, and the foam and splashes in the form of bubbles, they pass through the pores of the corrugated paper, which accelerates the release of foam to the outer side of the paper for gas extraction, i.e., the oil saturated with foam is additionally crushed on the porous corrugated paper of the cylindrical filters 8 due to the difference in vacuum between the closed inner cavity A of the filters and the vacuum in the housing 1 degasser (see Fig. 4, Fig. 7).

Because the vacuum in the inner cavity A of the filters is less, and in the middle of the body 1 of the degasser, the value of the vacuum is greater, the output of foam or bubbles is ensured on the outer porous corrugated paper of the filters 8 (see Fig. 7).

The foam of the oil is additionally broken into small fractions, aimed at a larger area of fuel filters 8, why and

Extraction of moisture and gas occurs from the oil, which is thus dried and flows into the lower part of the housing 1 of the degasser. at,

The proposed liquid degasser allows for high-quality drying and degassing of transformer oil, and the reduced weight of the degasser to ZOO kg is beneficial for transportation and the degasser is less time-consuming during operation.
