Abstract

The invention provides a spiral feeder and a screw rod heating conveying type thermochemical energy storage system, and relates to the field of thermochemistry. The spiral feeder comprises a head section, a middle section and a tail section. A spiral conveying rod is arranged in a cavity of the middle section, and an electric heating device is further arranged in the cavity of the middle section;and the tail section is provided with a solid discharge port and an air outlet. The screw rod heating conveying type thermochemical energy storage system comprises the spiral feeder, and further comprises a dry tank, a wet tank, a condenser, a spraying device and a heat exchange pipe; a discharge port at the bottom of the wet tank communicates with a feeding port of the spiral feeder; a solid discharge port of the spiral feeder communicates with a feeding port of the dry tank; an air outlet of the spiral feeder communicates with an air inlet of the condenser, a liquid outlet of the condenser communicates with a liquid inlet of the spraying device, and a spray head of the spraying device extends into the wet tank; a discharge port at the bottom of the dry tank communicates with a feeding port of the wet tank; and the heat exchange portion of the heat exchange pipe is placed in the wet tank. The system is smaller in equipment volume and higher in energy storage density.

Description

technical field [0001] The invention relates to the technical field of thermochemistry, in particular to a screw feeder and a screw heating and transporting thermochemical energy storage system. Background technique [0002] At present, the lack of flexibility in the adjustment of my country's power system and the rigidity of power grid dispatching and operation have made it difficult for the system to fully adapt to the requirements of the new situation. In some areas, there have been serious problems of abandoning wind, light and water, and there are contradictions in regional electricity and heat consumption. protrude. In order to achieve my country's goal of 15% and 20% of non-fossil energy consumption in 2020 and 2030, respectively, and to ensure the safe supply of electricity and heat demand for people's livelihood, it is necessary to focus on improving the regulation capacity and operating efficiency of the power system. From the load side , power supply side, and powe...
