Ice storage device of dynamic energy storage device

Abstract

The invention discloses an ice storage device of a dynamic energy storage device. The ice storage device is connected with an external refrigeration compressor and comprises a tank body in which water is accommodated; a thermal insulating layer is arranged at the outer layer of the tank body; wherein a heat exchanger connected with the refrigeration compressor is arranged at the bottom of the tank body and inlet and outlet pipes of the heat exchanger are arranged in an interlayer bucket-shaped structure; a rotational cutter is arranged coaxial with the interlayer bucket-shaped structure and can rotate relative to the interlayer bucket-shaped structure; and the rotational cutter is provided with at least one layer of scraping cutters for scrapping ice. According to the ice storage device of the dynamic energy storage device, as a near distance scrapping cutter mode is adopted for the inlet and outlet pipes of the heat exchanger, the ice at the surface of the interlayer bucket-shaped structure is scraped off in time, so that the heat exchange efficiency is improved; and meanwhile a stirring function to the icy water inside the tank body is kept, thereby ensuring that the energy is stored through the icy water inside the tank body during a low power use period, and the icy water can be accessed to central air-conditioning directly to be used as circulating refrigerating water during a high power use period.

Description

technical field [0001] The invention relates to a dynamic energy storage device, in particular to an improvement of an ice storage device in the dynamic energy storage device. Background technique [0002] In the existing technology, with the gradual shortage of energy, how to make energy more in line with the actual needs of society is a key direction of current technology development. Since the current power supply is the most important form of basic energy, for energy producers, such as thermal power plants that use coal to generate electricity, it is impossible to control and fine-tune their generators to meet the actual changes in electricity demand. Generate electricity continuously for a period of time. [0003] In the actual needs of the society, usually when the demand for electricity during the day is higher than that at night, and the demand for electricity is high, there will be a concentrated need for electricity, and once the power generation is insufficient, ...

[0008] However, in this way, the working time is very short during the low-peak power consumption period, and a certain thickness of ice will be generated on the heat exchanger tube. When the ice layer reaches a thickness of 5 mm, the evaporation temperature of the ice entering and leaving the tube will decrease. will decrease, resulting in a decrease in cooling efficiency and an increase in energy consumption by more than 50%.
