Description

The utility model relates to the field of electric power industry, namely to devices for converting the kinetic energy of the flow of produced/injected fluid inside the pipeline into electricity. It is used to ensure uninterrupted power supply at well pads.

A rotary turbogenerator device is known (Patent RU 2746349 C1 IPC F25B 11/00, F01D 15/10, F01D 1/02, B01D 45/12, B01D 45/16, publ. 12.04.2020). The turbogenerator contains a turbine and a generator mounted inside the main pipeline with high pressure gas. Before the turbine inside the main pipeline, a swirler, a liquid separation section and a gas-liquid flow selection section are installed in series and axially. The gas-liquid flow selection section is connected by an additional pipeline to the main flow after the turbine, and a control valve is installed in the additional pipeline. The invention makes it possible to provide an autonomous power supply to oil and gas production facilities, as well as to ensure the operability of the turbogenerator in the presence of liquid in the gas flow entering the turbogenerator inlet, and when the operating conditions of the turbogenerator change, such as the input flow rate and the electrical load connected to the turbogenerator.

The disadvantages of the known device include the lack of the possibility of prompt repair by stopping the flow, since the additional channel present in the device can only be used to control the rotation speed and cannot be used for fluid flow during the repair period.

A device for heating a coolant is also known (Patent RU 49960 U1 IPC F24H 4/00, F24D 3/02 publ. 10.12.2005). A device containing a unit driven by a source of mechanical energy for accelerating and forcing a coolant and supplying it to an external closed pipeline circuit, characterized in that a gas turbine is used as a source of mechanical energy, operating at the expense of excess gas energy (gas pressure drop) at gas distribution points, which, together with the unit for acceleration and injection of the coolant, is located in the pipeline connected in parallel to the gas pressure control unit of the main gas pipeline (in the bypass pipeline).

The disadvantages of the known device include the inability to insert directly into the pipeline, due to the large area of the device, as well as the lack of a filter device to prevent the ingress of dispersed particles into the pipeline.

The technical task of the proposed device is to create a device for generating energy due to the kinetic energy of the fluid flowing through the pipeline.

The technical result of the claimed device is to provide an autonomous and reliable power supply to consumers at hydrocarbon production and transportation facilities (well pads) and to ensure the continuity of the oil production process during the period of repair and maintenance work.

The purpose of this utility model is:

1) ensuring uninterrupted power supply at well pads, through the use of a filter element that traps dispersed particles that cause erosive wear of the rotor blades and generator housing;

2) performance of routine maintenance and operational repairs without stopping the flow of fluid;

3) reduction of costs for additional provision of electric power to the well pad.

This goal is achieved by inserting a device into the pipeline, which includes: a non-magnetic copper housing, a bypass line connected to the housing using special bushings, a bypass valve, connecting and servicing couplings, a shut-off valve, a fixed rotary turbine operating in a liquid medium and allowing short-term work in the gas, connected to the generator shaft, as well as a filter of large dispersed particles, to prevent them from entering the working element of the rotary turbine. The rotary turbine serves as a drive for the energy generator, which is connected to the consumer by an electrical circuit.

The utility model is illustrated by the description and diagram in Fig.1.

The presented device consists of a non-magnetic copper body (2) cut into the pipeline (1) and fixed on it with couplings (10), a bypass valve (7), service couplings (9), a shut-off valve (11), a bypass line (8) connected to the housing with bushings (13), a rotary turbine (4) fixed in the housing with quick-release fasteners (3), a filter (12) attached to the housing (2) with a quick-release device (14), an electrical circuit ( 5) and energy consumer (6).

The principle of operation is as follows: before the start of operation, a non-magnetic copper body of the device (2) is cut into the pipeline (1) and fixed on it with the help of couplings (10). When the liquid or short-term gas fraction moves through the pipeline (1), the transported medium converts the kinetic energy of the flow into electricity, by converting the translational movement of the produced/injected fluid into the rotational movement of the turbine rotor in the stationary stator. To prevent dispersed particles from entering the turbine rotor, a filter (12) is installed in front of the rotor turbine (4), fixed in the housing with quick-release fasteners (3), fixed to the housing (2) with a quick-release device (14). A bypass valve (7) is provided in the body (2), which redirects the movement of the fluid flow to the bypass line (8), connected to the main body by bushings (13), and a shut-off valve (11), blocking the possibility of flow through the rotary turbine (4), allowing repair of the rotary turbine (4) and/or replacement of the filter (12). Additionally, for this purpose, service couplings (9) are provided in the housing (2), with the help of which it is possible to isolate from the housing (2) a section with a rotary turbine (4) and a filter (12) fixed to the housing (2) using a quick-release device ( 14). After repair and / or replacement, the section with the rotary turbine (4) and the filter (12) is inserted into the housing (2), fixed with the help of service couplings (9). The gate valve (11) opens and the liquid is diverted through the bypass valve (7) through the rotary turbine (4). The transmission of electric current is carried out by means of an electric circuit (5) to the energy consumer (6).

The advantages of this utility model are: a non-magnetic material for the manufacture of the casing, a filtering device for trouble-free operation of a rotary turbine, ease of operation and repair, the ability to operate the device without changing the technological process of hydrocarbon production.
