Cold accumulating device by ice

Abstract

The invention discloses an ice storage arrangement, which comprises an ice storage tube, at least one ice-making pipe, and at least 3 ice-melting pipes. The ice-making pipe and the ice-melting pipes are arranged in the ice storage tube. Wherein, on each ice-melting pipe, a row of water-jetting holes are provided on the pipe wall facing the axial line of the ice storage tube and / or on the pipe wall departing from the axial line of the ice storage tube; each row of water-jetting holes comprise at least 10 downward tilting water-jetting holes that are distributed along the axial direction of the ice-melting pipe; the water in the ice-melting pipes jets through the water-jetting holes into the ice storage tube to form CW and / or CCW vortex; it is preferably that the included angle between the opening direction of each water-jetting hole and the section of the ice-melting pipe is 30-60 degree; and it is even more preferably that the ice storage arrangement further comprises an ice-melting bypass mechanism, which comprises a lower collecting box communicated with the lower end of the ice-melting pipe, a bypass pipe and a solenoid valve for turning on / off the bypass pipe, wherein, the bypass pipe is communicated with the lower collecting box and a water supply port.

Description

technical field [0001] The invention relates to an ice cold storage device, in particular to a direct contact swirl ice-melting cold storage device. Background technique [0002] Cold storage technology is a practical and comprehensive technology emerging to realize peak shifting and valley filling of the power grid. In developed countries, due to the active encouragement and advocacy of various power companies and government energy departments, the cold storage technology has been continuously improved and matured, and its popularization and application has been developed rapidly. With the continuous development of our country's economy, the gap between peak and valley power supply in cities and towns continues to increase. In order to ensure the sustainable, stable and rapid development of the national economy, improve and alleviate the tension in power supply, the State Planning Commission and the power department have made Short-term and long-term planning requirements ...

AI Technical Summary

Problems solved by technology

However, the sleeve-type inner and outer ice-melting ice-storage cylinder disclosed in the No. 200420017434 patent has a complex structure, and does not fully utilize the swirling flow enhanced heat transfer technology, so the ice-melting efficiency is still not fully improved.
