Description

An online cleaning structure for atomizers Technical Field

[0001] This utility model belongs to the field of atomizer cleaning technology, specifically relating to an online atomizer cleaning structure. Background Technology

[0002] Gas valve atomizers play a crucial role in oil and gas production sites. Their main function is to atomize various agents when they are added to pipelines, ensuring that the agents can fully dissolve in the fluid and thus exert their intended effects.

[0003] Because atomizer nozzles are typically very small in diameter, dirt or impurities can easily clog them, affecting atomization and, in severe cases, completely blocking them. Furthermore, some medications are highly viscous and adhere strongly to the inner walls of the tubing. When these medications pass through the atomizer nozzle, they tend to adhere to the inner wall, reducing the atomizer's throughput and thus affecting atomization. Therefore, during atomizer maintenance, the nozzle must be disassembled for cleaning and inspection.

[0004] Because atomizers are prone to clogging, operators must continuously monitor the chemical dosing, which increases their workload and labor intensity. Especially in the production of high-sulfur gas wells, if antifreeze is not added to pipelines or equipment in a timely manner, the gaseous water in saturated water-bearing natural gas can easily form hydrates within the pipeline. This can lead to overpressure problems in the pipeline or equipment and may even cause serious safety accidents.

[0005] In traditional operations, when an atomizer becomes clogged, immediate action is required: first, the gas supply must be shut off, then the pressure released before the nozzle can be safely disassembled for cleaning and inspection. After cleaning and inspection, purging and replacement procedures must be followed to ensure the system's cleanliness and safety. Only after these steps are completed and the system passes a pressure test can normal production resume. However, the cleaning of the atomizer inevitably affects the normal production of the gas well, typically resulting in a decrease in output and a direct negative impact on the company's economic benefits. Therefore, improving the reliability of the atomizer and reducing the frequency and impact of cleaning and maintenance are crucial for ensuring stable gas well production. Summary of the Invention

[0006] In view of this, the present invention provides an online cleaning structure for atomizers to solve the problems of high cost, poor adaptability, stability and reliability of existing auxiliary tools.

[0007] The technical solution is as follows:

[0008] A key feature of an online cleaning structure for atomizers is that it includes:

[0009] A flange having a first mounting hole and a second mounting hole arranged radially opposite each other thereon;

[0010] The atomizer assembly is installed in the first mounting hole;

[0011] The plugging valve assembly, installed in the second mounting hole, includes a plugging head and a push rod. The plugging head can move directly toward the first mounting hole under the action of the push rod and form a seal on the inner end of the first mounting hole.

[0012] Using the above solution, when the atomizer needs to be cleaned, maintained, or replaced, the push rod can be used to push the plug head to seal the first mounting hole, and then the atomizer assembly can be removed. During this process, because the first mounting hole is in a blocked state, there will be no leakage or other safety risks even if production is not stopped or pressure is released. The structure is ingenious, environmentally friendly and energy-saving, and it also reduces the labor intensity of operators.

[0013] Preferably, the inner end of the first mounting hole has a flared opening, and the head end of the plug head is adapted to this flared opening. This design improves the sealing performance and reduces the impact on the atomizing agent.

[0014] Preferably, the plugging head is fitted with a first sealing ring at its tip. This combination of soft and hard sealing significantly improves the sealing performance.

[0015] Preferably, the atomizer assembly includes an atomizer body and a nozzle, and after the atomizer assembly is installed, the end face of the nozzle is located outside the flared end. This design facilitates clogging with the plugging head, improving overall safety and reliability.

[0016] Preferably, the plugging valve assembly includes a valve body that is threaded into a second mounting hole, a push rod that passes through the valve body and is threaded into the valve body, and a plugging head that is detachably connected to the push rod. This design is simple in structure, easy to manufacture and disassemble, and conducive to widespread implementation.

[0017] Preferably, the inner end of the second mounting hole has a receiving portion, the diameter of which is greater than or equal to the maximum outer diameter of the plugging head. With this design, during normal production, the plugging head can retract into the receiving portion, reducing the scouring effect of gas on the plugging head and extending its service life.

[0018] Preferably, the second mounting hole further includes an internal thread section A and a variable diameter section arranged sequentially from the outside to the inside. The valve body has an external thread section A adapted to the internal thread section A, and a columnar section adapted to the variable diameter section. This design improves the valve body's sealing performance and reduces the risk of leakage during installation.

[0019] Preferably, the valve body has an internally threaded section B that mates with the push rod, and a sealing cavity filled with sealing material. The outer end of the valve body has a compression sleeve that mates with its threads. This design further improves the dynamic sealing performance of the push rod installation, enhancing safety and reliability.

[0020] Preferably, a handwheel is installed at the outer end of the push rod. This design facilitates the rotation of the push rod and is relatively easy and effortless.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The online cleaning structure for atomizers provided by this utility model allows for the disassembly, cleaning, maintenance, or replacement of atomizers without interrupting production or depressurization. The structure is safe, reliable, easy to implement, has a long service life, and low maintenance costs. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Referring to Figures 1 to 7, an online cleaning structure for an atomizer according to this application mainly includes a flange 100, an atomizer assembly 200, and a plugging valve assembly 300. The flange 100 is a conventional circular flange structure. In addition to the flange hole arranged in the thickness direction, it also has a first mounting hole 110 and a second mounting hole 120 arranged radially opposite each other. The atomizer assembly 200 is installed in the first mounting hole 110, and the plugging valve assembly 300 is installed in the second mounting hole 120. It includes a plugging head 310 and a push rod 320. The plugging head 310 can move directly opposite the first mounting hole 110 under the action of the push rod 320, and forms a blockage at the inner end of the first mounting hole 110 near the center of the flange.

[0032] The inner end of the first mounting hole 110 has a flared opening 111, which is a regular cone shape. The head end of the plug 310 is adapted to the flared opening 111. When the plug 310 is inserted into it, the circumferential sidewall of the plug 310 is in contact with the flared opening 111 to form a hard seal.

[0033] To further improve the sealing performance, a first sealing ring 311 is fitted on the head end of the plug head 310. The first sealing ring 311 forms a soft seal with the flared mouth 111, which can greatly improve the sealing effect of the plug head 310.

[0034] The atomizer assembly 200 in this application is an existing structure, mainly including the atomizer body 210 and the nozzle 220. However, the installation structure is different from the existing structure. After the atomizer assembly 200 is installed, the end face of the nozzle 220 is outside the flare 111, that is, it is not within the range of the flare 111, but it is close to the flare 111. This allows enough space for the entry of the plug head 310, and the flare 111 can also help diffuse the agent, reducing the impact of installation. A second sealing ring 211 is fitted on the atomizer body 210.

[0035] As shown in the figure, the plugging valve assembly 300 in this application also includes a valve body 330, which is threadedly engaged with the second mounting hole 120. The push rod 320 passes through the valve body 330 and is threadedly engaged with the valve body 330. The plugging head 310 and the push rod 320 are detachably connected, usually by a threaded connection.

[0036] The inner end of the second mounting hole 120 has a receiving portion 121, the diameter of which is greater than or equal to the maximum outer diameter of the plug head 310, ensuring that the plug head 310 can be fully retracted into the receiving portion 121. Furthermore, the second mounting hole 120 also includes an internal thread section A122 and a reducing section 123 arranged sequentially from the outside to the inside. The maximum outer diameter of the plug head is greater than the inner diameter of the reducing section 123. The valve body 330 has an external thread section A331 adapted to the internal thread section A122, and a columnar section 332 adapted to the reducing section 123.

[0037] The valve body 330 has an internal thread section B333 that mates with the push rod 320, and a sealing cavity 334, as shown in the figure. The inner diameter of the sealing cavity 334 is larger than the inner diameter of the internal thread section B333. It is filled with sealing material (usually preferably a polytetrafluoroethylene ring or block, not shown in the figure). Both ends of the sealing cavity 334 are provided with gaskets 335. The outer end of the valve body 330 has a compression sleeve 340 that mates with it. The compression sleeve 340 has a through hole for the push rod 320 to pass through. After installation, the compression sleeve 340 abuts against the gasket 335 on the outer side.

[0038] A handwheel 400 is installed at the outer end of the push rod 320, which allows the push rod 320 to be rotated relatively easily.

[0039] Referring to Figures 1 to 7, an online cleaning structure for an atomizer is installed by first assembling the plugging valve assembly 300, without initially connecting the plugging head 310 to the push rod 320. After the plugging valve assembly 300 is installed, it is integrally mounted onto the flange 100. Once secured, the push rod 320 is rotated so that its inner end is within the center hole area of ​​the flange 100. Then, the plugging head 310 is connected and installed. Finally, the push rod 320 is rotated in the opposite direction to allow the plugging head 310 to enter the receiving part 121. The installation of the atomizer assembly 200 is basically the same as the existing one, except that attention needs to be paid to the position of the nozzle.

[0040] When the atomizer assembly 200 needs cleaning and maintenance, without stopping production or depressurizing, screw in the push rod 320 to move it directly towards the first mounting hole 110 until the circumferential sidewall of the plug head 310 and the first sealing ring 311 are tightly abutted against the flared mouth 111, thus sealing the inner end of the first mounting hole 110. Then the atomizer assembly 200 can be disassembled directly. After the maintenance of the atomizer assembly 200 is completed, it can be directly reinstalled and then the push rod 320 can be screwed out to allow the plug head 310 to re-enter the receiving part 121. The whole process will not stop production and will have little impact on pressure, which is of great significance for ensuring the stable production of gas wells.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
