Abstract

The invention discloses a sensible heat accumulating type direct steam generation system based on parallel connection regulation as well as a method. The sensible heat accumulating type direct steam generation system comprises an outlet header, outlet connecting pipes, a heat accumulator, heat exchange tube bundles, a first temperature sensor, a sealed thermal insulation layer, motor operated valves, inlet connecting pipes, an inlet header, a circulating water pipe, a flow meter, a control cabinet, a water replenishing connecting pipe, a water storage tank, a second temperature sensor and a third temperature sensor. With the method of parallel connection of heat exchange pipelines, the problem that the heat exchange area per unit and the heat exchange power per unit are reduced continuously due to continuous reduction of the temperature in a heat exchange process of the sensible heat accumulator is solved effectively by changing the heat exchange area and reducing flow in single pipeline, the stability of output power of the system is improved, an effective solution is provided for replacing small and medium-sized coal burning boilers and electric boilers and providing stable steam with peak-valley electricity, and very good application prospect is provided.

Description

technical field [0001] The invention relates to a sensible heat storage direct steam generation system and method based on parallel regulation, and belongs to the technical field of sensible heat storage and heat exchange. Background technique [0002] As an important part of energy utilization, energy storage plays a very important role in industrial energy conservation and the utilization of renewable energy. The energy provided in the form of thermal energy accounts for a considerable proportion of energy utilization, so heat storage technology has become a key part of energy storage technology. In the energy storage of intermittent energy sources and the recovery and utilization of industrial waste heat, sensible heat storage has been widely used due to its simple principle, mature technology, abundant material sources, and low cost. [0003] Sensible heat storage is the process of using the heat capacity of heat storage materials to store or release heat by increasing ...
