Description

Technical Field

[0001] This utility model belongs to the technical field of high-risk stress wear-resistant pipeline components, specifically relating to a wear-resistant and alarm-enabled double expansion joint pipeline compensator. Background Technology

[0002] During the silicon particle reaction process, the medium inside the equipment and pipeline reaches a high temperature of 650°C. During this process, axial and lateral deformation will occur due to pipeline stress. Therefore, pipeline compensators are needed to meet the existing working conditions. Although ordinary single-section expansion joints can meet the axial displacement, they cannot meet the lateral displacement. Therefore, a double-section corrugated pipe is designed to meet both axial and lateral displacement requirements.

[0003] Firstly, the medium used in silicon particle production is highly flammable and explosive when exposed to air, posing an extreme danger. Therefore, reliable expansion joints are required to meet these requirements. A double-layered corrugated pipe design is needed, with the single layer requiring temperature and pressure resistance. The inner corrugated pipe is in direct contact with the medium, with a gap between the inner and outer corrugated pipes. A nitrogen purging port and a pressure warning port are designed on the outer corrugated pipe. The pressure warning port is a T-junction, with one end connected to a local pressure gauge and the other to a remote pressure gauge. A pressure limit alarm is set on the central control DCS interface. If an abnormality is detected, the outer corrugated pipe can also provide protection, allowing time for a safe shutdown. During silicon particle production, the gaseous medium in the pipeline contains silicon powder, which can cause erosion in the high-speed flow of the silicon powder-containing medium. While the thicker pipe walls can be controlled, the thinner walls of the expansion joints cannot be allowed to be eroded by silicon powder. Secondly, the medium must avoid contact with metals during the reaction process to prevent contamination. Therefore, to avoid erosion and metal contamination, both conditions must be met simultaneously. Utility Model Content

[0005] This utility model is achieved through the following technical solution: A wear-resistant, alarm-enabled dual expansion joint pipe compensator includes an inlet end pipe, a first corrugated pipe assembly, an intermediate pipe assembly, a second corrugated pipe assembly, and an outlet end pipe connected in sequence. Both the first and second corrugated pipe assemblies contain a flow guide assembly. Each assembly includes an outer corrugated pipe and an inner corrugated pipe, with a gap between them.
