[0002] In the ship desulfurization system, a sampling branch pipe is provided on the desulfurization pipe to sample and monitor the medium status in the desulfurization pipe. If the sampling pipe is designed in the conventional way, the sampling pipe is prone to blockage during the actual commissioning, installation and use, and the medium is insufficient or even absent during sampling, which makes cleaning inconvenient. According to research, for the horizontally arranged desulfurization pipe, the main reason is that the sampling branch pipe is located at the lower end of the desulfurization pipe, which makes it easy for impurities precipitated at the bottom to enter the sampling pipe through the sampling branch pipe, causing the sampling pipe to be blocked; and it is also difficult to sample when the flow rate of the medium is too fast, especially when the main pipe is arranged vertically.
[0003] Therefore, a desulfurization sampling structure, a desulfurization pipeline system and a ship are needed to solve the above problems. Utility Model Content

[0034] During the desulfurization process of the desulfurization pipeline system, it is necessary to sample and test the medium. In order to prevent impurities from entering the sampling tube, eliminate the blockage problem, and facilitate fast and effective sampling, such as Figure 1-Figure 2 As shown, the utility model provides a desulfurization sampling structure. The desulfurization sampling structure includes a sampling branch pipe 2, a sampling pipe 3 and a connecting assembly.
[0035] The sampling branch pipe 2 is fixedly arranged on the desulfurization pipe 1, and the sampling branch pipe 2 is connected with the desulfurization pipe 1. The sampling pipe 3 is inserted in the sampling branch pipe 2, and the first end of the sampling pipe 3 extends into the desulfurization pipe 1. The first end of the sampling pipe 3 has a collection port 33, and the direction of the collection port 33 is opposite to the flow direction of the medium in the desulfurization pipe 1. The connecting component is arranged between the sampling branch pipe 2 and the sampling pipe 3, and the connecting component is used to connect the sampling pipe 3 with the sampling branch pipe 2.
[0036] During the sampling process, since the first end of the sampling tube 3 extends into the desulfurization tube 1, the first end of the sampling tube 3 protrudes relative to the bottom of the desulfurization tube 1, preventing impurities at the bottom of the desulfurization tube 1 from entering the sampling tube 3, thereby avoiding blockage. Since the first end of the sampling tube 3 has a collection port 33, the direction of the collection port 33 is opposite to the flow direction of the medium in the desulfurization tube 1, so that the medium can quickly enter the sampling tube through the collection port 33, and sampling can be performed quickly and effectively.
[0037] Furthermore, the connecting assembly includes a first connecting flange 21, a second connecting flange 31 and a connecting piece, the first connecting flange 21 is fixedly arranged on the sampling branch pipe 2, the second connecting flange 31 is fixedly sleeved on the sampling tube 3, and the first connecting flange 21 and the second connecting flange 31 are connected by a connecting piece. Specifically, the first connecting flange 21 is located at one end of the sampling branch pipe 2 away from the desulfurization tube 1. The first connecting flange 21 and the second connecting flange 31 are connected by a plurality of connecting pieces, so as to facilitate fixing the sampling tube 3 to the sampling branch pipe 2. In the present embodiment, the connecting piece is a bolt, and the bolt connection is adopted to facilitate the installation and disassembly of the sampling tube 3, so as to facilitate the subsequent cleaning and maintenance of the sampling tube 3. If the sampling tube 3 is damaged, it can also be quickly replaced. In other embodiments, the connecting assembly may also adopt a snap-on structure or a threaded connection structure, without making too many restrictions here.
[0038] Furthermore, the second connection flange 31 is welded to the sampling tube 3. By welding the second connection flange 31 to the sampling tube 3, assembly is facilitated and the stability of the connection between the sampling tube 3 and the second connection flange 31 can be ensured. In other embodiments, the second connection flange 31 and the sampling tube 3 can also be designed as an integrated structure, and no excessive restrictions are made here.
[0039] Furthermore, a sealing ring is provided between the first connecting flange 21 and the second connecting flange 31. By providing the sealing ring, the gap between the first connecting flange 21 and the second connecting flange 31 can be blocked, thereby preventing the medium entering the sampling branch pipe 2 from leaking through the gap between the first connecting flange 21 and the second connecting flange 31. In some embodiments, a mounting ring groove can be provided on the end face of the first connecting flange 21 or the end face of the second connecting flange 31, and the sealing ring is embedded in the mounting ring groove, and the sealing ring protrudes relative to the mounting ring groove. After the first connecting flange 21 and the second connecting flange 31 are connected by a connector, the sealing ring is squeezed and deformed, thereby blocking the gap. By providing the mounting ring groove, the installation and positioning of the sealing ring are facilitated.
[0040] Furthermore, a switch valve 4 is provided on the sampling tube 3, and the switch valve 4 can control the on-off of the sampling tube 3. By providing the switch valve 4, the sampling tube 3 can be controlled, opened when the collected medium needs to be discharged into the sampler, and closed after the sampling is completed.
[0041] Furthermore, a third connection flange 32 is fixedly provided at the second end of the sampling tube 3, and the third connection flange 32 can be docked with the sampler. The third connection flange 32 is provided to facilitate docking with the sampler.
[0042] Furthermore, a filter screen 5 is provided at the collection port 33 of the first end of the sampling tube 3, and the filter screen 5 is detachably provided on the sampling tube 3. Specifically, the first end of the sampling tube 3 is beveled to form an inclined collection port 33. In other embodiments, a hole may be directly opened on the sampling tube 3 as the collection port 33, and no excessive restrictions are made here. By providing the filter screen 5, impurities entering the medium in the sampling tube 3 can be further filtered out, and the risk of blockage can be further eliminated. Moreover, since the filter screen 5 and the sampling tube 3 are detachably provided, it is convenient to quickly replace the filter screen 5 after the filter hole of the filter screen 5 is blocked.
[0043] Furthermore, the length of the sampling tube 3 extending into the desulfurization tube 1 is half of the inner diameter of the desulfurization tube 1. By setting the depth of the sampling tube 3 extending into the desulfurization tube 1, smooth sampling can be ensured, and impurities deposited in the desulfurization tube 1 can be prevented from entering the sampling tube 3, while excessive influence on the flow of the medium in the desulfurization tube 1 can be avoided.
[0044] This embodiment also provides a desulfurization pipeline system, including the above desulfurization sampling structure, which can prevent impurities from entering the sampling tube 3, eliminate the blockage problem, and facilitate fast and effective sampling.
[0045] This embodiment also provides a ship, including a hull and the above desulfurization pipeline system, the desulfurization pipeline system is arranged on the hull, which can prevent impurities from entering the sampling tube 3, eliminate the blockage problem, and facilitate fast and effective sampling.
[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
