Description

The utility model relates to the field of cleaning equipment from oil sludge using liquid or steam, namely to mobile units designed for steaming in-pipe cleaning devices, such as pistons-separators (PRV) or in-pipe cleaning pigs (ICP), used when cleaning the internal surface of oil pipelines from asphalt, resin and paraffin deposits.

A mobile installation for steaming in-pipe cleaning devices is known [Patent RU No. 173821, IPC V08V 3/02, publ. 09.13.2017], containing a cylindrical chamber installed on a supporting structure with nozzles that are connected to a manifold placed on the chamber for supplying steam, wherein the chamber consists of a base and an upper cover, while the nozzles are installed in the upper part of the chamber cover, a manifold for supplying the pair is placed on the outer surface of the chamber cover, a frame is installed inside the base of the chamber for placing an in-line device, made with the possibility of circular rotation, in addition, a drain pipe is installed in the lower part of the chamber base for connection with a container for collecting water-oil emulsion.

The disadvantage of this installation is that the work is carried out inside the housing by service workers manually using respiratory protection, a special tool that prevents sparking, since the surface of the treatment devices (DU) contains paraffins and petroleum products that can ignite and poison workers. In addition, for washing different diameters of the OU, replacement is required on the frame using bolted connections for a certain size of flange mounting, and replacement of nozzles is also not provided.

The closest in technical essence and achieved result is a container for steaming a pipeline OU [Patent RU No. 209750, IPC V08V 3/02, publ. 03.22.2022], which contains a housing with a lid mounted on a support, on the inner sides of which there are attachment points for the cleaning device, designed to ensure its rotational movement, a manifold with steam supply nozzles is mounted along the length of the container, and the attachment point for the head part of the cleaning device consists of a faceplate, a shaft with a bearing assembly and a scroll handle, and the opposite fastening unit includes a clamping spindle, a flywheel, a spindle rotation locking lever on which a conical locking device is mounted, and a pipe is mounted in the lower part of the housing

The disadvantage of this container is the limitation of the diameters of the steamed op-amps, only DN 300, 350, 500, 700. To steam op-amps with diameters larger than DN700, a different design of the clamping spindle is required. In addition, large-diameter cleaning devices are heavy, which is why they can bend and become deformed or fail to support their own weight and tip over from their mounting points.

The technical problem to be solved by the claimed utility model is the creation of an installation for steaming DUs after passing them through an oil pipeline, ensuring cleaning of asphalt, resin and paraffin deposits from the entire surface of DUs of all diameters by rotating the structural elements, due to which the entire surface of the cleaning device is steamed, preventing prolonged steam hits one point without causing any harmful effects on them.

The technical result achieved by implementing the utility model is to ensure the versatility of steaming op-amps with diameters from DN300 to DN1200 in one chamber without damaging their elements, which increases manufacturability and efficiency.

The claimed technical result is achieved due to the fact that the mobile installation for steaming op-amps has a cylindrical chamber with a two-door hatch and external levers, by rotating which, the rigging slats inside the chamber are rotated, allowing the collectors for steam supply to be fixed in different positions for high-quality steaming of all op-amps diameters, which are suspended on a chain, regulated by chain winches outside the installation; from the outside, the manifold is designed to discharge steam into a container for collecting water-oil emulsion, where a manifold is also installed, all nozzles of which are installed at an angle to each other, to allow steaming of hard-to-reach places, and a drain pipe is installed to the container.

In a mobile installation, the two-door hatch opens in different directions, while a seal made of technical rubber is installed along its perimeter. A pipe with a safety valve is embedded in the upper part of the body, and a container for collecting water-oil emulsion is welded to the trailer chassis.

The design of the mobile installation is illustrated by drawings, where:

in fig. 1 - shows a side view of a mobile installation for steaming cleaning devices;

in fig. 2 - shows a section of a mobile installation for steaming cleaning devices;

in fig. 3 - shows a general view of a mobile installation for steaming cleaning devices with an open hatch;

in fig. 4 - shows a fragment of a mobile installation for steaming cleaning devices.

Mobile installation for steaming cleaning devices includes

a welded structure, which is a cylindrical chamber 1 with blank end walls, on the top of which a two-door hatch 2 is mounted, connected to the base of the chamber using hinge joints (not shown in the drawings), in the open state of the door hatch, on which bracket handles 3 are installed , rest on supporting spring struts 4, which are connected to the hatch doors via a hinge-lever mechanism 5. The spring struts, in turn, are installed on a container for collecting the water-oil mixture 6, welded to the chassis of the trailer 7;

upper and lower manifolds (8, 9, respectively) with nozzles 10. Nozzles 10 with holes ∅4 mm in the amount of sixteen pieces are attached to fittings (not shown in the drawings) of manifolds 8, 9 via threaded connections (it is possible to replace the nozzle without welding). The collectors 8, 9 are mounted in metal rigging rails 11, which allow the collectors 8, 9 to be fixed in different positions, depending on the diameter of the op-amp, by moving pins (not shown in the drawings). The rigging rails 11, in turn, are welded to the shafts 12, which have bearing units at the intersection of the chamber body 1 and the shafts 12. From the outside, the shafts 12 are welded to the rotary levers 13, 14 for the upper and lower manifolds, respectively, which are mounted at both ends of the chamber. The swing arms are equipped with 15 handles for a comfortable grip for the operator. Hoses 16 are designed to supply steam to the upper and lower collectors and are fixed at one end to the collectors, the other end to the separation pipe 17. Pipe 18 from the outside of the pipe 17 is equipped with a tee to drain steam into a container for collecting oil-water emulsion 6, where the collector is also installed 19, installed along the width of one side of the container 6.

The nozzles 20 of the collector 19 are installed at an angle to each other to allow steaming of hard-to-reach places. A ball valve 21 is mounted on pipe 20 to shut off the steam supply, and pipe 20 is also equipped with a quick-release coupling element 22.

A drain pipe 23 with a 90° outlet is mounted to the bottom of the tank for collecting oil-water emulsion with the possibility of attaching a pressure rubberized hose for draining into the drain.

Inside chamber 1, four chains 24 hang at an equal distance from each other, onto which cleaning devices are installed. One end of the chains is equipped with a lifting hook 25, the other end is wound on chain winches 26 installed on the outer periphery of chamber 1. Hook 25 can be attached to metal eyes 27 welded to one hatch door 2 and to the base of chamber 1. Reciprocating movement of chains 24 carried out through a metal box 28 equipped with a rubber sleeve to seal chamber 1.

In the upper part of chamber 1 there is a 29 DN 100 pipe with a 30 membrane-type safety valve (to relieve excess steam pressure from the container). If the pressure in the chamber increases, the membrane ruptures and steam escapes into the atmosphere through pipe 29 and valve 30.

A folding platform for maintenance 31 is located on both sides of the installation and attached with hinges to a container for collecting the water-oil mixture 6. On the outside of the installation, at the end of chamber 1, there is a thermometer 32, the remote sensor of which (not shown in the drawings) is installed inside chamber 1.

The device works as follows.

The installation is transported to a prepared site next to the drainage tank. The service platform (31) is moved to the working position. Holding the handles (3), move the two-door hatch (2) of the chamber (1) to the “open” position. The functionality of the lifting hooks (25) is checked and the hoses (16) are securely fastened to the internal pipe (17). The upper manifold (8) and the lower manifold (9) are installed in the required holes on the rigging rails (11), the choice of hole depends on the diameter of the op-amp being stored. The collectors (8, 9) are positioned in such a way as to ensure unobstructed installation of the op-amp inside the chamber (1). The slinging of the mechanically pre-cleaned op-amp is carried out, and the axis of the op-amp must be located horizontally. The op amp is fed into the chamber so that the circuits (24) are located between the op amp cuffs.

Next, the hook (25) is installed from position 1 to position 2 (Fig. 3). The hatch (2) of the chamber (1) is brought to the “closed” position. The OS is lifted using chain winches (26) installed on the outer periphery of the hatch door (2), and the chains (24) wound on the winches (26) pass through metal boxes (28) equipped with a rubber sleeve to seal the chamber (1) , A pressure rubberized hose attached to the nozzle (23) is secured to the neck of the drainage container (not shown in the figure).

Next, the steam collection pipeline from the mobile steam unit (MSU) is installed. The pipeline from the polyurethane foam is secured with a quick-release coupling (22). PPUs are located outside the site at a distance of at least 15 meters. Heated steam at a temperature of 140-180°C is supplied to the pipe (17), to which hoses (16) from the upper and lower manifolds (8, 9, respectively) are connected, through nozzles (10) (nozzles), the steam enters the cleaning device and washes away dirt. After 3-5 minutes, the operator rotates the collectors around the cleaning device using the rotary levers (13, 14), while holding the handles (15). During the entire steaming time (30-40 minutes), the operator monitors the temperature inside the chamber using a thermometer (32) with a remote sensor (not shown in the figure), and also monitors the removal of contaminants into the drainage from the side. After enough time has passed for steaming, the ball valve (21) located on the outside of the manifold is opened, so steam is supplied to the manifold (19), installed in the tank for collecting the water-oil mixture (6), along the width of one of its sides. Next, the PPU operator stops the steam supply. The removal of the op-amp from the chamber is carried out in the reverse order after the chamber and the op-amp have completely cooled (T<30°C), and if necessary, the op-amp in the chamber is delivered to the base.

The useful model allows high-quality steaming of the entire surface of both DN300 and DN1200 OUs in one chamber, without causing any harmful effects on them.
