Description

Technical Field

[0001] The utility model relates to the technical field of synthesis furnace steam pipelines, in particular to a cleaning production device in a synthesis furnace steam system. Background Art

[0002] In the chlor-alkali process, the proper functioning of the synthesis furnace equipment is crucial. However, the presence of chlorides and other impurities in the pure water used in the synthesis furnace's steam section has led to leaks in multiple key locations. First, the synthesis furnace barrel, a core component of the entire system, can suffer leaks that could severely impact production efficiency and safety. Leaks have also been reported in the synthesis furnace's water supply steam pipeline and the steam pipeline from the synthesis furnace to the flash tank. These pipelines were damaged during transportation due to water quality issues, increasing maintenance and operating costs. Therefore, a comprehensive inspection and repair of the affected pipelines and equipment is necessary. This includes replacing damaged components, repairing leaks, and strengthening anti-corrosion measures to ensure the integrity and durability of the equipment. However, repairing leaks with welding poses a significant safety hazard. In the piping system of high-temperature, high-pressure equipment such as the synthesis furnace, welding operations require heating and cooling the piping structure, which can cause deformation and stress concentration in the piping material, introducing new defects and cracks, thereby increasing the brittleness and risk of damage to the piping system.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A clean production device in a synthesis furnace steam system, comprising a left-side external holding pipe and a right-side external holding pipe with the same structure as the left-side external holding pipe, wherein a main holding pipe and a secondary holding pipe with the same structure are respectively installed on the outer walls of the left-side external holding pipe and the right-side external holding pipe away from each other, and a snap-fit ​​structure is provided on the outer walls of the main holding pipe and the secondary holding pipe, and an external threaded holding pipe structure and an internal threaded holding pipe structure for threaded connection are respectively installed inside the main holding pipe and the secondary holding pipe, and a pull bolt structure is provided on the front and rear outer walls of the left-side external holding pipe and the right-side external holding pipe.

[0005] Preferably, the main holding tube includes an upper semicircular tube and a lower semicircular tube fixed on the outer wall of the upper and lower parts of the right-side external holding tube on the same side.

[0006] Preferably, the embedding structure includes two symmetrical U-shaped hoops on the front and rear outer walls of the upper semicircular tube and two symmetrical trapezoidal blocks fixed on the front and rear outer walls of the lower semicircular tube, and the U-shaped hoops and trapezoidal blocks are embedded in each other.

[0007] Preferably, the external threaded tube-holding structure includes a main threaded half tube fixed on the top wall of the upper semicircular tube and a secondary threaded half tube fixed on the bottom wall of the lower semicircular tube.

[0008] Preferably, the internal threaded tube holding structure includes an internal threaded half tube 1 and an internal threaded half tube 2 fixed at the upper and lower ends inside the auxiliary tube holding, and the tubular structure composed of the internal threaded half tube 1 and the internal threaded half tube 2 is threadedly matched with the tubular structure composed of the main threaded half tube and the auxiliary threaded half tube.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the clean production device in the synthesis furnace steam system forms two pipe protection layers at the leakage point by providing structures that cooperate with each other, such as a card-embedded structure and an internal threaded pipe-holding structure, thereby effectively preventing steam leakage. The use of a pull-bolt structure and a card-embedded structure can make the left-side external pipe holding structure, the right-side external pipe holding structure, and the main pipe holding structure fixed and tightened, ensuring the firmness and stability of the pipe connection. For the high-temperature and high-pressure synthesis furnace steam pipeline, this can effectively prevent the pipeline from loosening and leaking due to pressure and temperature changes, thereby improving the reliability of the pipeline. Compared with the welding leak repair operation that requires local heating and cooling of the equipment, this structural form will not cause stress changes to the pipeline, thereby ensuring the stability of the pipeline structure outside the leakage point.

A snap-fit ​​structure 4 is provided on the outer wall of the pipe 6. An externally threaded pipe-holding structure 5 and an internally threaded pipe-holding structure 8 for threaded connection are installed inside the main holding pipe 3 and the auxiliary holding pipe 6, respectively. The main holding pipe 3, the right-side external holding pipe 2, and the externally threaded pipe-holding structure 5 are preliminarily connected through the snap-fit ​​structure 4. A bolt structure 7 is provided on the front and rear outer walls of the left-side external holding pipe 1 and the right-side external holding pipe 2. The bolt structure 7 and the snap-fit ​​structure 4 securely fasten the left-side external holding pipe 1, the right-side external holding pipe 2, and the main holding pipe 3, ensuring the firmness and stability of the pipe connection.

[0019] The main holding tube 3 includes an upper semicircular tube 301 and a lower semicircular tube 302 fixed on the outer wall of the upper and lower parts of the right-side external holding tube 2 on the same side. The locking structure 4 includes two symmetrical U-shaped hoops 401 on the front and rear outer walls of the upper semicircular tube 301 and two symmetrical trapezoidal clamping blocks 402 fixed on the front and rear outer walls of the lower semicircular tube 302. The U-shaped hoops 401 and the trapezoidal clamping blocks 402 are locked with each other.

[0020] The external threaded pipe holding structure 5 includes a main threaded half pipe 501 fixed on the top wall of the upper semicircular pipe 301 and a secondary threaded half pipe 502 fixed on the bottom wall of the lower semicircular pipe 302. The internal threaded pipe holding structure 8 includes an internal threaded half pipe 1 801 and an internal threaded half pipe 2 802 fixed at the upper and lower ends of the auxiliary pipe 6. The tubular structure composed of the internal threaded half pipe 1 801 and the internal threaded half pipe 2 802 is threadedly matched with the tubular structure composed of the main threaded half pipe 501 and the secondary threaded half pipe 502. The right-hand side externally held pipe 2 is For example, when the externally threaded pipe-holding structure 5 and the main pipe-holding structure 3 are installed at a leak point or a location to be protected in the steam piping system of the synthesis furnace, the main threaded half pipe 501, the upper semicircular pipe 301, the secondary threaded half pipe 502, the lower semicircular pipe 302, and the upper and lower portions of the right-side externally mounted pipe-holding structure 2 are all installed on the outer circumference of the pipe. During this process, the U-shaped clamp 401 and the trapezoidal clamping block 402 are fastened together to preliminarily connect each pipe-holding structure to the pipe. The design of the snap-fit ​​structure 4 ensures a tight fit between the pipe-holding structure and the pipe interface.

[0021] The bolt pulling structure 7 includes two symmetrical bosses fixed on the front and rear outer walls of the upper and lower parts of the right-side external holding pipe 2. A bolt column is hinged between the two bosses at the same horizontal height. A clevis nut sleeve is installed on the top of the bolt column. The staff flips the bolt column upward so that the bolt column is vertically facing upward, and then screws a clevis nut sleeve on the bolt column. The clevis nut sleeve moves on the bolt column, so that the upper and lower parts of the left-side external holding pipe 1 and the right-side external holding pipe 2 are tightened, thereby ensuring that the holding pipe is firmly fixed on the pipeline and resisting loosening or displacement due to pressure changes.

[0022] When the embodiment of the present application is in use, the staff first takes out the left-side external holding tube 1 and the right-side external holding tube 2, disassembles the left-side external holding tube 1 and the right-side external holding tube 2 and puts them on the leakage point or the place to be protected of the synthesis furnace steam pipeline system. At this time, the external thread holding tube structure 5 and the internal thread holding tube structure 8 are directly in contact with the leakage point or the place to be protected of the synthesis furnace steam pipeline system to form a first sealing layer. At this time, the staff uses the card embedding structure 4 to connect the main holding tube 3, the right-side external holding tube 2 and the external thread holding tube structure The structure 5 is preliminarily connected, so that the main holding pipe 3, the right-side external holding pipe 2, and the external thread holding pipe structure 5 form a complete holding pipe structure. Then the staff continuously screws the right-side external holding pipe 2 and the external thread holding pipe structure 5, and makes the external thread holding pipe structure 5 approach the direction of the internal thread holding pipe structure 8. Then the external thread holding pipe structure 5 and the internal thread holding pipe structure 8 are threadedly connected at the leakage point or the place to be protected of the steam piping system of the synthesis furnace until the thread is connected to the limit position. Then the staff again tightens the bolt structure 7 through the pull bolt structure 7. Tighten the right external holding pipe 2 and the left external holding pipe 1, so that the right external holding pipe 2 and the left external holding pipe 1 form a second sealing layer on the outside of the external thread holding pipe structure 5 and the internal thread holding pipe structure 8, thereby completing a double-layer sealing treatment for the leakage point or the place to be protected of the synthesis furnace steam pipeline system. By installing the left external holding pipe 1, the right external holding pipe 2 and the external thread holding pipe structure 5 and the internal thread holding pipe structure 8, two pipeline protection layers can be formed at the leakage point, thereby effectively preventing steam leakage, and using the pull bolt Structure 7 and the embedded structure 4 can fix and tighten the left-side external holding pipe 1, the right-side external holding pipe 2, and the main holding pipe 3, ensuring the firmness and stability of the pipeline connection. This can effectively prevent the loosening and leakage of the pipeline caused by pressure and temperature changes for the high-temperature and high-pressure synthesis furnace steam pipeline, thereby improving the reliability of the pipeline. Compared with the welding leak repair operation that requires local heating and cooling of the equipment, this structural form will not cause stress changes in the pipeline, thereby ensuring the stability of the pipeline structure outside the leakage point.
