Description

The utility model relates to the oil and refining industry and can be used to clean oil pipes from asphalt-resin-paraffin deposits for the purpose of their subsequent use for repair and re-use, including for cleaning oilfield tubing arriving for repair from oil production areas.

A known installation for cleaning oil pipes by pulsed impact on the deposits of the air flow moving along the pipe created by the pneumatic pulse generator attached to one of the ends of the pipe (RU 2288788).

There is also known an installation for cleaning the internal cavities of tubing from paraffin deposits, containing a gas generator based on an aircraft engine, a container for accommodating a packet of pipes to be cleaned, and a device for separating and collecting molten paraffin. At the entrance to the device for separating and collecting paraffin there is a control flap that controls the gas flow. During operation of the installation, the gas generator produces a high-temperature gas stream, which is sent to the packet of pipes to be cleaned (RU 95103485).

The disadvantage of these installations is the insufficient efficiency of cleaning pipes from deposits and the inevitability of frequent shutdowns due to overload of the cleaning chamber, which leads to a loss of process productivity and significant emissions of cleaning products into the working area due to the inability to ensure the tightness of the cleaning chamber during its reload.

Closest to the proposed utility model is the well-known steam-gas-turbine unit for cleaning oil pipes, containing a gas generator based on an aircraft engine, a pipe cleaning chamber made in the form of a flat heat-insulated pencil case with a lid, equipped with an automatic pipe loading and unloading system, including input and output racks, made with a slope, a gas outlet channel from the aircraft engine to the output unit, nozzle nozzles with a steam supply manifold for water generation and nozzles, collectors p water supply for sprinkling of exhaust gases (RU 2226129).

A disadvantage of the known installation of the prototype is that at the stage of loading and unloading the cleaning chamber, due to the lack of devices for automatically opening and closing the lid, a vapor-gas mixture is released into the surrounding space, which complicates the maintenance of the installation and reduces the reliability of its operation. A system for locking the lid of the cleaning chamber is not provided; a system for raising and lowering the lid is not indicated.

The technical task of the proposed utility model is to create an installation devoid of these disadvantages.

The technical result of the proposed utility model is to improve the environmental safety and reliability of the installation, as well as to simplify its maintenance.

The specified technical result is achieved by the fact that in a steam and gas turbine installation for cleaning oil pipes containing a gas generator based on an aircraft engine, the pipe cleaning chamber is made in the form of a flat heat-insulated pencil case with a lid, equipped with an automatic pipe loading and unloading system, including input and output racks, made with a slope, a gas outlet channel from the aircraft engine to the output block, nozzle nozzles with a steam supply manifold for water formation and nozzles, a water supply manifold for sprinkling of exhaust gases, the cleaning chamber is equipped with a hydraulic system for raising and lowering the lid and a hydraulic locking system for the lid, the cleaning chamber lid is equipped with a sealing seal and mounted on hinged locks, elevators are installed at the corners of the lid, while one end of the elevator is fixed to the installation foundation, and the other on the lid.

The hydraulic locking system and the hydraulic system for raising and lowering the lid of the cleaning chamber simplifies the maintenance of the installation and increases the reliability of its operation. At the same time, the cleaning chamber can be equipped with a lid with sound-absorbing filler, which further increases the reliability and environmental friendliness of the installation.

The use of the cover of the cleaning chamber, equipped with a sealing seal and sound-absorbing filler, allows to reduce the amount of gas-vapor emissions of the installation by 35-40% compared to the prototype, and the noise impact on the environment by 20-40% compared to the prototype depending on the material and coating thickness .

The elevators installed at the corners of the lid of the cleaning chamber are preferably pneumatic or hydraulic cylinders, which further simplifies and increases the ease of maintenance of the installation.

The installation is preferably provided with a container for collecting cleaning products, which is made in the form of a sealed chamber, as well as a tray for collecting cleaning products, which further increases the environmental safety of the process.

The gas generator is equipped with an air intake, for example, knee-shaped, preferably with a protective mesh.

The gas generator may be equipped with a water injection system in front of the aircraft engine compressor.

Providing the gas generator with a knee-shaped air intake with a protective mesh allows avoiding the ingress of extraneous mechanical impurities into the system, which additionally ensures the safety and reliability of the installation.

The gas generator can be equipped with a fuel preparation unit for working on natural and / or associated gas or for working on kerosene, or for working on diesel fuel, or for working on a water-fuel emulsion, which ensures reliable uninterrupted operation of the installation.

The ability to control the temperature and composition of the gas-vapor flow allows the installation of a water injection system before and / or after the aircraft engine compressor. Installing a water injection system in front of the aircraft engine compressor allows you to also adjust the engine power.

The cleaning chamber can be equipped with a control circuit for the temperature of vaporization, which allows to maintain stable operation of the installation.

The air intake can be additionally equipped with sound-reflecting deflectors, as well as a sound absorption system installed in the air intake shaft, which reduces the acoustic load on the personnel serving the installation.

The installation can be equipped with a transport system for automatic loading of unloading pipes, as well as a trolley for moving cleaning products, which further simplifies the process of servicing the installation.

The nozzle nozzle can be equipped with a noise cover, for example, with sound-absorbing filler, which reduces the acoustic load on the personnel serving the installation.

The output unit can be equipped with a centrifugal separator, as well as a jet-type scrubber-adsorber or shock-inertial-type adsorbent scrubber installed at the outlet of the unit, which allows purification of exhaust gases.

The system of automatic loading and unloading of pipes includes inlet and outlet racks, which can be equipped with pushers, for example, with a hydraulic drive, while the inlet and outlet racks can be equipped with vibrators, which increases the efficiency of the installation and further simplifies its maintenance.

The gas generator, in order to increase the efficiency of the cleaning process, can be equipped with a system for supplying water or aqueous absorbent solutions to steam generation in a hot stream behind the aircraft engine turbine.

The cleaning process can be carried out as follows.

On the slipway - a table forming the working surface of the cleaning chamber, a preformed package of pipes to be cleaned is laid. Under the working surface of the table is a bypass channel (bypass), which is a pencil case of rectangular cross section. Through this channel, a high-pressure hot stream exiting the nozzle nozzle is directed to bypass the working surface with pipes during loading or unloading of the cleaning chamber. The rotation of the flow and its direction into the bypass channel is carried out using a special rotary plate located throughout the cross section at the outlet of the nozzle nozzle of rectangular cross section. The damper is driven by a pneumatic or hydraulic cylinder.

The cover of the cleaning chamber has a U-shape, its walls are made of multilayer material. Around the perimeter of the lid, to prevent gas and vapor emissions into the atmosphere, a heat-resistant seal is fixed so that the lid and the working surface of the slipway table form a channel of rectangular cross section.

To the left and right of the side surfaces of the camera is the transport system of loading and unloading. On one side of the lid, a package of pipes is prepared using a special pipe layer, in automatic mode, the pipe package is counted and formed for laying in the cleaning chamber. On the other side of the lid there is a rack on which pipes are rolled out from the cleaning chamber, ending with special pockets, from which the cleaned pipes are taken away for further processing. The working surfaces of the cleaning chamber and the transport system are located in the same plane inclined at an angle, preferably 2-3 °, with a slope towards the discharge pockets. The lid rests on the hinged supports, which are also locks. At the corners of the lid installed lifts: hydraulic or pneumatic cylinders. One end of the lift is mounted on a support, which is the foundation of the installation, and the other end, the “earring” of the rod, is pivotally mounted on the cover. In order to load the cleaning chamber, one side of the lid is lifted with the help of elevators, and the other lies on the hinged supports and is locked from sliding with locks. The prepared tube package lies on the preparation rack. The stops controlled by hydraulic or pneumatic cylinders keep the tube package from unauthorized rolling and loading of the cleaning chamber. The loading of the cleaning chamber is carried out by command only with the cover on the loading side fully raised and with a fully formed tube package (the number of pipes in the package depends on their diameters). After the cleaning chamber has loaded, the lid is closed simultaneously and the high-pressure vapor-gas stream coming from the nozzle nozzle is transferred from the working position to the “bypass channel” to the “cleaning chamber” position. Thus, emissions of combined-gas mixture into the environment are eliminated, the environmental safety of the process is increased; the presence of a lid locking system increases the reliability of the entire installation. The system of opening and closing the lid itself does not require additional labor, is simple and reliable in operation. After closing the lid, the process of cleaning pipes from deposits occurs due to the melting of resin paraffins and sediment entrainment by a high-speed flow into the system for collecting and collecting cleaning products (output unit). After cleaning the pipes, the steam-gas stream is transferred to the bypass channel, the hinged supports are released from the locks and the lid is opened (one side is lifted) due to the extension of the two hydraulic cylinder rods from the discharge side and the pipes are scooted along the inclined plane of the table of the cleaning chamber onto an inclined plane inclined at the same angle rolling rack or immediately into the pockets of the finished product. If several pockets are installed, then the first pocket from the camera is filled first, after filling it, it is closed with special crossbars that form an inclined plane along which the next processed bag will roll into the next pocket, etc. until all pockets are full. Pipes are removed from the filled pockets for further processing according to the technological process.
