RU53594U1 - INSTALLATION FOR WASHING THE BAR OF THE BAR ROD INSTALLATION - Google Patents

Abstract

The utility model relates to stand-alone devices for flushing the outer surfaces of oilfield equipment and, in particular, rods of sucker rod rigs. The technical essence lies in the fact that the washing process takes place in a washing chamber with sealing sides (gates) having a reversible roller table for moving under a stream of steam and a washing solution of a cartridge with bars in the amount of 56 pieces. The washing process is carried out in an automated mode.

Description

The utility model relates to the field of technological washing plants. The installation is intended for use in the oil and gas industry and specifically can be used for washing in the production environment of the outer surfaces of the rods of sucker rod rigs, sucker rod pumps (SHGN), packers, etc. equipment from all types of industrial pollution. The washing process is determined by the thermal effect of the high-speed steam-water stream on field deposits (PO).

Known installations containing a bath, a loading chamber with a lid, a chamber for accumulating sludge, means for feeding the solution and giving it a swirling motion in the loading chamber, a channel for returning the solution to the loading chamber and supports for laying pipes obliquely.

The disadvantages of these plants are: low productivity, low quality cleaning, a large proportion of manual labor.

The closest analogue of the utility model is the installation for flow-through washing of oilfield pipes according to the patent of the Russian Federation 2194582 publication date 12/20/2002, which contains a heat-insulating bath consisting of a loading chamber, a bottom channel and two side vertical channels with windows for the circulation of the washing solution. Gravity separator with chambers for sludge and collection of heavy and light fractions of asphalt-resin-paraffin deposits. The bathtub is equipped with two vertical electric water-jet installations with knee-shaped water conduits and superactive propellers, an ejector pump, an electric pump for pumping the solution, and a temperature sensor for the washing liquid, and the bathtub with a service platform is made on a single frame. An operator with a control panel is located in a thermally insulated control cabin.

The disadvantages of this installation, which we have chosen as a prototype, are the bulkiness of the structure, the presence of a bath with and superactive

propellers, the use of manual labor when opening the lids of the gravity separator.

The problem solved by the use of this utility model is to increase the productivity and quality of washing the rods by using a high-speed steam-water stream that washes the rods (and other equipment), laid in special cartridges that can be horizontally moved in the direction perpendicular to the steam-water mixture, thanks to an automated process control system bar wash cycle.

The technical essence of the claimed installation lies in the fact that the installation for washing the rods of a rod well installation, comprising a supply and a receiving roller table; a washing chamber with a roller table and a tray for washing rods, a steam manifold, a pipeline of a washing solution (water); sludge tank; moreover, the washing chamber is equipped with special cassettes for the installation of rods and a system for the automated control of the technological process of washing, starting from the supply to the feed roller table and ending with the output from the receiving roller table.

Figure 1 presents a diagram of a utility model. The installation comprises a feed roller 10, a receiving roller 1, a washing chamber 3 with a roller 8, a steam manifold 7 consisting of 4 horizontal pipes with holes for the passage of steam, a washing solution pipe 6 consisting of 4 horizontal and 20 vertical pipes with holes for supplying a washing solution , cassettes for laying rods 4, sludge tank 12, cabinet 11 with equipment for automated process control. The steam manifold 7 and the horizontal pipes of the washing fluid pipe 6 are located on the lid of the washing chamber 3. The opening and closing process of the inlet 9, the outlet 2, the reciprocating cassette 4 with the rods 5 inside the washing chamber 3, the steam and washing solution carried out automatically by a cabinet 11 with equipment for automated process control.

The proposed device operates as follows.

The 56 rins to be washed 5 in the amount of 56 are stacked in the cassette 4. The cassette 4 with the rods 5 of the feeding roller 10, after raising the slide 9 of the washing chamber 3, enters the cleaning chamber 3. Then the slide 9 is lowered, the steam supply through the steam manifold 7 is turned on and the supply of washing solution through pipeline 6. The high-speed circulating flow of washing solution as a result of hydrodynamic, thermal and solvent-emulsifying action melts and flushes out industrial pollution from the equipment being washed, taking away heavy and light fractions of the PP from the pan of the washing chamber 3 into the sludge tank 12. The lower part of the vertical pipes of the washing pipe 6 mounted on both sides inside the washing chamber 3 is located below the base of the cartridge 4. During the washing cycle, the cartridge moves back and forth direction perpendicular to the steam-water washing mixture inside the washing chamber 3 with an automatically set cycle: 8-16 movements. The stroke of the cassette rods inside the sink is 3 meters. Thus, the rods are washed in the cassette with heating and steam blowing from almost four sides. Roller 8 carries out the reciprocating movement of the cartridge 4. After a specified number of cycles, the output gate 2 rises and the cartridge rolls onto the receiving roller 1, from where it is transferred to the workshop for disassembling the cartridge. Modes can be used both with heating the bar when steam is supplied, or simply with washing with a washing solution.

The movement of the cassette is controlled by “presence” sensors (BVC), which provide signals for working out the washing machine operation program and ensure the cyclical operation and safety of the washing process by the automation cabinet 11. A frequency converter is provided in the drive part of the roller conveyor line, which ensures smooth line start and roller conveyor reversal lines when practicing washing cycles without jerking, and also allows you to change the speed of the cartridge along the line, when you return an empty cartridge from the unloading conveyor to the conveyor ng loading through the washing itself with increased speed along the entire line, which reduces the time of a full cycle of washing the rods.

The gates 2 and 9, installed at the entrance to the washing chamber and at the exit from it, ensure tightness during the washing of the rods. Raising and lowering the gates is carried out by an electric drive through a rack-and-pinion gear.

The installed sensors of the extreme positions of the gates are also electrically connected with the cycle of the rod washing process.
