Abstract

The invention provides an active pipeline flow dividing device which comprises a header pipe, a transition connecting pipe and a multi-flow-path pipe, the multi-flow-path pipe comprises an outer pipe and at least one inner pipe, the outer pipe is connected with the transition connecting pipe, and the inner pipe is arranged in the outer pipe in a penetrating mode and fixedly connected to the outer pipe; and a rim pump is mounted in each inner pipe. According to the active pipeline flow dividing device, under the condition that the flow of the main pipe is certain, the flow of the inner pipe can be independently controlled according to requirements through an additional pressure head provided by the rim pump located in the inner pipe, so that the flow proportion of the inner pipe and the outer pipe is adjusted, and the device is compact in structure, wide in adaptability and convenient and accurate in flow dividing proportion adjustment; operation control is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of fluid pipeline transportation, in particular to an active pipeline diversion device. Background technique [0002] In the industrial field, it is often necessary to use pipelines for fluid transportation. In some cases, it is necessary to divide the pipelines to make them change from a single-flow flow to a multi-flow flow. The general flow structure mostly adopts passive flow, that is, branch pipelines The proportion of fluid flow distribution is constant, which can be uniform distribution or non-uniform distribution. [0003] However, for some conveying pipelines with different operating conditions, it is usually required that the fluid flow distribution ratios between the branch pipelines are different under different operating conditions. For example, for a shell-and-tube centralized heat exchanger, it mainly includes two cooling systems for heat exchange. The heat exchange between the inner pipe an...
