Novel pipeline supporting mode

Abstract

The invention provides a novel pipeline supporting mode. The mode comprises a parallel supporting beam, and an FRP slurry spraying main pipe is arranged on the outer surface of the upper end of the parallel supporting beam; the FRP slurry spraying main pipe and the parallel supporting beam are arranged in parallel; a saddle and an FRP winding are arranged on the outer surfaces of the FRP slurry spraying main pipe and the parallel supporting beam; the position, close to the rear end, of the outer surface of the FRP slurry spraying main pipe is fixedly connected with FRP slurry spraying branch pipes. The other end of each FRP slurry spraying branch pipe is fixedly connected with a nozzle. According to the structure of the device, the occupied space of the parallel supporting beams is small;the installation height of the nozzles does not need to be integrally reduced, the spraying branch pipes do not need to be additionally provided with elbows or descend, only the angles of the nozzleson the two sides of the parallel supporting beam need to be adjusted, the machining problem of the glass fiber reinforced plastic branch pipes is solved, the erosive wear problem of the supporting beams is avoided, and meanwhile the fracture risk problem of the FRP slurry spraying main pipe is solved.

Description

Technical field [0001] The invention relates to the technical field of pipeline installation, in particular to a novel pipeline support method. Background technique [0002] When choosing FGD equipment for thermal power plants at home and abroad, the limestone / gypsum forced oxidation system has become the preferred wet flue gas desulfurization process. The key equipment is the desulfurization absorption tower. A multi-layer limestone slurry spray system is required in the desulfurization absorption tower, and the support of the FRP spray pipeline is mainly composed of carbon steel support beams lined with anti-corrosion layer structure. [0003] The FRP slurry spray pipe is usually fixed above the support beam, and the support beam and the FRP slurry spray main pipe are in a cross shape. Generally, in the desulfurization absorption tower, each layer of FRP slurry spray pipeline support beam is a combination of multiple support beams to form a support beam frame structure. Nozzle...

AI Technical Summary

Problems solved by technology

[0008] The first purpose of the present invention is to provide a new type of pipeline support. The structure of the device makes the space occupied by the parallel support beam less, the nozzle does not need to lower the installation height as a whole, and the spray branch pipe does not need to increase the elbow and drop arrangement, only need to adjust The angle of the nozzles on both sides of the parallel support beam not only solves the problem of FRP branch pipe processing, but also avoids the problem of scouring and wear of the support beam. At the same time, it solves the problem of the risk of fracture of the FRP slurry spraying main pipe
