Steam energy accumulating system for accumulating heat through off-peak electricity

Abstract

A steam energy accumulating system for accumulating heat through off-peak electricity comprises an electric steam boiler, a direct steam supply pipeline, a heat accumulating pipeline, a heat accumulating pipeline electric valve, a heat accumulating pipeline check valve, a steam distributing pipeline, a heating pipe, a liquid level transmitter, a drainage pipeline, a drainage pipeline electric valve, a water replenishing pipeline, a water replenishing pipeline electric valve, a make-up water pump, a heat releasing pipeline, a heat releasing pipeline check valve, an electric adjusting valve, a steam-water separator and a pressure transmitter. The tail end of the heat accumulating pipeline is connected in a steam heat accumulator. The heating pipe is connected to the steam distributing pipeline. The make-up water pump is connected with the water replenishing pipeline electric valve, and the heat releasing pipeline is connected with the steam accumulator. The heat releasing pipeline checkvalve, the electric adjusting valve, the steam-water separator and the pressure transmitter are mounted on the heat releasing pipeline in sequence. The steam energy accumulating system is small in occupied space and low in operation cost, water is adopted as a medium to store high-temperature high-pressure steam generated by off-peak electricity, and the steam is released for use at an electricityconsumption peak. The steam energy accumulating system can be widely used for the field of industrial and civil steam.

Description

technical field [0001] The invention relates to a steam energy storage system utilizing low-valley electric heat storage, which can be widely used in the fields of industrial and civil steam. Background technique [0002] Energy is the basis for human survival and development. With the development of society and economy, the demand for energy continues to increase, and the development and rational use of energy has attracted more and more attention. With the deepening of domestic large-scale coal-fired boiler pollution control work, coal-to-electricity conversion has increasingly become the main mode of clean energy. Many production-oriented industrial enterprises have adopted electric steam boilers to directly replace coal-fired steam boilers. However, the direct electric heating method of factories has led to very high cost of steam production, and the enterprises are overwhelmed. Contents of the invention [0003] The purpose of the present invention is to provide a st...
