Multi-tube-bundle heat storage system capable of adjusting pulse heat exchange amount

Abstract

The invention provides a pulse tube bundle heat storage system. The pulse tube bundle heat storage system comprises a heat storage tank, a pulse generation device and pulse tube bundles, wherein the pulse tube bundles are arranged in the heat storage tank and are connected with the pulse generation device; an inlet pipeline of the pulse generation device is connected with inlets of the pulse tubebundles; outlets of the pulse tube bundles are connected with the pulse generation device through an outlet pipeline; a plurality of pulse tube bundles are arranged; the pulse tube bundle heat storagesystem is characterized by further comprising a controller; the controller is used for detecting heat exchange amount of each pulse tube bundle, then calculating average heat exchange amount of the plurality of pulse tube bundles, and automatically adjusting pulse flow amount of each pulse tube bundle according to the average heat exchange amount. The pulse tube bundle heat storage system has a new structure; the pulse amount of single pulse tube bundle is automatically controlled, so that the heat exchange amount is controlled, and the overall heat exchange reaches uniform heat exchange.

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...

Problems solved by technology

However, the heat transfer uniformity of the above-mentioned pulsating tube bundle is not enough, and the amount of heat transfer is also small, so it needs to be improved, and a new structure of pulsating tube bundle and heat storage system should be developed.
