TECHNICAL FIELD

[0001] The utility model relates to desulfurization pipeline technical field, concretely to a new -type nonaromatic flue gas desulfurization pipeline making equipment. BACKGROUND

[0002] Desulfurization pipeline is the pipeline system for conveying sulfur-containing flue gas or acid-base solution, and is widely used in flue gas desulfurization system of electric power, chemical industry, metallurgy and other industries. In the production process of non-aromatic substances (such as alkanes, cycloalkanes), the composition of flue gas is complex, the concentration of sulfur compounds is high, and large particles of impurities may be entrained. The traditional desulfurization pipeline is prone to decline in the inner wall flatness due to flue gas corrosion, and the efficiency is reduced due to impurity accumulation, so the pipeline often needs to be replaced.

[0003] For the problem of quick disassembly and installation of the joint during pipeline replacement, the patent document with publication number CN219848834U discloses a production non-aromatic flue gas desulfurization pipeline, which comprises a pipe body, a connecting plate fixedly connected to the pipe body, limit blocks provided on both sides of the connecting plate, hole plates clamped and connected to both ends of the pipe body, limit grooves corresponding to the limit blocks provided on the hole plates, and the limit grooves are clamped and connected with the limit blocks. During installation, the connecting plate is fixedly connected to the outside of the pipe body, the hole plates are clamped to both ends of the pipe body, and the limit blocks on the connecting plate are clamped and connected with the limit grooves on the hole plates to preliminarily complete the stable installation of the hole plates. The outer wall of the pipe body is provided with a limiting mechanism, which comprises a fixed block, a round rod and a supporting plate. The round rod connects the fixed block and the supporting plate, the supporting plate is fixedly connected with the hole plate, the fixed block is fixedly connected with a limiting ring, and the limiting ring is clamped and connected with the pipe body.
