Example Embodiment

[0018] As attached figure 1 , 2 As shown in 3, the heat-tracing turbulent laminar fluidized drag reduction fluid transportation pipeline is composed of multiple single-section transportation pipelines 15 and a master controller 12. The single-section transportation pipeline 15 includes arcuate pipes 1, fluid electric heating pipes 2. Insulation layer 3, bolts 4, axial reinforcing ribs 5, pipe wall electric heating pipe 6, insulated wire 7, pipe upper cover 8, heating steel pipe 9, fluid temperature monitoring device 10, wall temperature monitoring device 11, temperature control The arched pipe is connected by welding or flange. The section of the arched pipe is an arch with the chord on the upper side and the arc length is greater than a semicircle. The upper pipe cover 8 is connected to the upper surface of the arched pipe chord by bolts 4 on both sides. The inner side of the upper cover of the pipe is provided with axial stiffeners 5 parallel to the axial direction of the pipe...

Abstract

The invention discloses a heat tracing turbulent layer fluidized drag-reducing flow conveying pipe and a method thereof. The heat tracing turbulent layer fluidized drag-reducing flow conveying pipe is formed by a plurality of single-section conveying pipes and a master controller. Each single-section conveying pipe mainly includes an arched pipe, a fluid heat tracing pipe, an insulating layer, a pipe wall heat tracing pipe, a pipe upper cover, a fluid temperature monitoring device, a wall temperature monitoring device and a temperature controller. The heat tracing turbulent layer fluidized drag-reducing flow conveying pipe aims at existing heating conveying of high-viscous and congealable fluid, combines the existing skin effect heat tracing technology and the fluid drag reducing control technology by aid of the design of the round conveying pipe arched fluid interface, and achieves control on the fluidized flow state of the fluid turbulent layer in the pipe near the fluid string surface on the basis of the congeal removing and viscosity reducing effects of the skin effect heat tracing technology by maintaining the temperature difference of the wall surface of the arched pipe and the fluid in the pipe. Thus, pressure drop loss of fluid during conveying can be further reduced, the conveying efficiency can be improved, and energy saving and consumption reducing can be promoted.

Description

technical field [0001] The invention relates to a heat-tracing type turbulent laminar fluidization drag-reducing fluid transport pipeline and its method, especially in the field of fluid transport, which is easy to condense or has a high viscosity at normal temperature, and becomes liquid or has a reduced viscosity after heating. Heat-tracing turbulent laminar fluidization drag-reducing fluid transport pipeline. Background technique [0002] There are four ways to transport industrial products or raw materials such as liquids or gases: road, rail, water and pipeline. Compared with other types, pipeline transportation has the characteristics and outstanding advantages of large transportation volume, less land occupation, airtight safety, easy management, high reliability, low energy consumption and low freight cost, so it has become the first choice for liquid or gas transportation. an ideal way. [0003] Long-distance transportation pipelines are divided into two types: is...
