Description

Technical Field

[0001] The utility model relates to the technical field of pipeline replacement, in particular to a biomass gas purification circulation pipeline. Background Art

[0002] The biogas desulfurization and purification device in the sludge treatment plant has been in operation for more than ten years, and some facilities have reached the designed service life. In particular, the pipelines of the circulating water cooling system have suffered serious corrosion and water leakage, which not only affects the circulating effect of the cooling water, but also poses a great safety hazard. In order to ensure subsequent safe production, it is necessary to comprehensively replace the pipelines of the circulating water cooling system, the pre-cooling tower and the post-cooling tower.

[0003] Since this transformation is carried out based on the internal disassembly and assembly of the device, and the production device of combustible gas needs to be kept running normally, it is necessary to install temporary pipes on the inlet and return water main pipes of the compressor (2 sets), desulfurization workshop, pre-cooling tower, post-cooling tower, solution cooler, and regenerator cooler unit respectively.

[0004] The applicant has searched a large number of pipeline connection methods in the prior art, and various problems generally exist. For example, when a certain sludge treatment plant replaced the pipelines of the circulating water cooling system, it was found that the traditional connection method required long-term shutdown, which affected the production progress; and when a certain factory used the existing pipeline connection device, water leakage frequently occurred, resulting in equipment damage and production interruption. In short, there are various problems: it is relatively complex during installation and disassembly, requires professional tools and technicians, increasing the maintenance difficulty and time cost. The existing pipeline connection methods are prone to poor sealing after long-term use, resulting in water leakage and affecting the normal operation of the system. The existing pipeline connection devices are often designed for specific equipment, with poor versatility, and different connection devices need to be equipped for different equipment, increasing the procurement and maintenance costs. When the prior art disassembles pipelines, water leakage is likely to occur, posing a safety hazard, especially in high-temperature and high-pressure environments, which may lead to greater accidents.

[0005] Therefore, it is very necessary to design a biomass gas purification circulation pipeline that is convenient for installation, connection and replacement. Content of the Utility Model

When disassembly is required, only need to pull up the first pulling plate 10, and the first pulling plate 10 drives the tapered end of the first tapered clamping rod 4 to move out of the first clamping groove 9. By providing a second telescopic spring 16, the second telescopic spring 16 pushes the second limiting plate 14, and the second limiting plate 14 drives the tapered end of the second tapered clamping rod 13 to cooperate with the second clamping groove 17. When the first tapered clamping rod 4 is pulled outward, the first telescopic spring 8 is in a compressed state, and it is easy to push the first tapered clamping rod 4 back to its original position.
