Embodiment Construction

[0046] figure 1 A pulsating tube bundle with three risers is shown. Such as figure 1 The three standpipe pulsating tube bundles shown include the middle standpipe 14, the left standpipe 161, the right standpipe 162 and the coil pipe 12. Heat pipe 15, the end portion of adjacent heat exchange tube 15 communicates, makes a plurality of heat exchange tubes 15 form a series structure, and makes the end of heat exchange tube 15 form heat exchange tube free end ( figure 1 The position where the load-bearing block is set); the entrance of the middle standpipe 14 is connected with a pulsating flow generating device, which is used to generate a pulsating flow in the heat exchange tube 15, thereby further promoting the vibration of the elastic heat exchange tube bundle to enhance heat transfer and reduce Fouling.

[0047] The coil 12 includes a left coil 121 and a right coil 122, one side of the middle riser 14 is connected to the inlet of the left coil 121, the other side is connect...

Abstract

The invention provides a three-riser pulsating tube bundle. The three-riser pulsating tube bundle comprises a middle riser, a left risers, a right riser and a plurality of coil tubes, wherein each coil tube comprises a plurality of arc-shaped heat exchange tubes, the ends of adjacent heat exchange tubes communicate, the plurality of heat exchange tubes form a series structure, the ends of the heatexchange tubes form free ends of the heat exchange tubes, the inlet of the middle riser is connected with a pulsating flow generating device for generating pulsating flow in the heat exchange tubes,the coil tubes comprise a left coil tube and a right coil tube, one side of the middle riser is connected with the inlet of the left coil tube, the other side is connected with the inlet of the rightcoil tube, the outlet of the left coil tube is connected with the left riser, and the outlet of the right coil tube is connected with the right riser. According to the pulsating tube bundle with the novel structure, more coil tubes are arranged in a limited space to increase the vibration range of the pulsating tube bundle, so that heat transfer and descaling are enhanced.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a pulsating tube bundle and a molten salt heat storage tank thereof. Background technique [0002] Shell-and-tube heat exchangers are widely used in energy, power, petrochemical and other industrial fields. The enhanced heat transfer technology of heat exchangers is of great significance to energy saving and consumption reduction. Among them, passive enhanced heat transfer technology is an important research direction at present because it does not require external high-quality energy input to achieve the purpose of enhanced heat transfer. [0003] The use of fluid-induced vibration of heat transfer elements to achieve enhanced heat transfer is a form of passive enhanced heat transfer, which can transform the strict prevention of fluid vibration induction in the heat exchanger into the effective use of vibration, so that the transmission elements can operate at low flow r...
