Abstract

An ultrasonic heat transfer enhancing tube shell heat exchanger is provided, which belongs to the technology field of energy-saving of heat exchanger of industry. The heat exchanger comprises a shell, a heat exchanger tube, a tube side inlet, a tube side outlet, a shell side inlet, a shell side outlet, a first tube plate, a second tube plate, a clapboard, a baffle and a power ultrasonic transducer. The power ultrasonic transducer inserts from the central circular hole of the left end surface of the shell, passes through a circular casing and the central circular hole of a first tube plate in sequence, penetrates a circular hole support and is sealed in the shell side space of the heat exchanger by a sealing cover plate. The ultrasonic wave is projected radially along the power ultrasonic transducer, intensifies liquid oscillation adopting ''cavitation effect'' produced by the ultrasonic wave when spreading in the liquid, reduces liquid motion viscosity coefficient, enhances the heat exchange efficiency of the heat exchanger tube under the condition of low flow velocity of liquid, greatly reduces energy consumption of power plant and has obvious energy-saving effect. In addition, the ''cavitation effect'' of the ultrasonic wave can prevent the surface of the heat exchanger tube from scale formation and has strong adaptability and operability.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to an ultrasonic-enhanced heat-exchange shell-and-tube heat exchanger, which belongs to the technical field of industrial heat exchange and energy saving. Background technique [0002] Shell and tube heat exchangers are widely used heat exchange equipment in the industrial field. Especially in special occasions such as high temperature, high pressure, and poisonous, shell and tube heat exchangers will have better applicability, but the shell and tube heat exchangers currently used Heater also has the problem of low heat transfer efficiency. In order to improve the heat transfer efficiency of the shell-and-tube heat exchanger, many studies have been carried out on the heat transfer enhancement in the tube of the shell-and-tube heat exchanger. Improve the surface properties of heat exchange tubes, such as threaded tubes, surface porous tubes, etc.; (2) Change the form of shell-side ...
