Abstract

The invention relates to a vane impulse generator that includes valve case, liquid channel, installing end surface, bevel gear, static vane, active vane, and through hole. The liquid channel is straight channel, and the static vane and active vane is plumped installing in the liquid channel. The rotating shaft of vertical taper gear passing through the center of static vane and connecting to the active vane center, and the rotating shaft of level taper gear connects to the speed adjusting motor. The invention is simple structure, convenient to be processed, low energy consumption and impulse frequency could be directly adjusted.

Description

(1) Technical field [0001] The invention relates to a vane type pulsation generator. (2) Background technology [0002] The blade type pulsation generator is mainly used in pipelines where pulsating flow enhances heat transfer, mass transfer and certain chemical reactions, and provides pulsating flow for these processes. [0003] Pulsating flow refers to the fluid whose characteristic parameters such as velocity, pressure or flow change periodically due to external excitation. This kind of fluid is not uncommon in engineering practice and daily life, such as human arterial blood and respiratory airflow are both pulsating flows. The fluid is very different from ordinary steady-state flow fluids in terms of flow, heat and mass transfer, and it can very effectively enhance fluid flow and heat and mass transfer effects. At present, experiments in the literature have proved that the heat transfer enhancement of the fluid can be up to 20 times higher, and the mass transfer effec...
