Problems solved by technology

In a dynamic ice-making system, a large number of ice crystals in the ice slurry generator have a strong tendency to propagate upstream along the supercooled water pipe (subcooled heat exchanger). If no effective blocking is used, the ice crystals will quickly spread to the supercooled in the heat exchanger, thereby freezing the heat exchanger and interrupting the ice making cycle

Abstract

The invention discloses an indirect heat exchange type ice crystal spread-resistant device. The indirect heat exchange type ice crystal spread-resistant device comprises a jet pipe and a heat exchange pipe, wherein the jet pipe comprises a speed-increasing section and a jet section; the speed-increasing section is arranged at the rear end of the jet pipe and the jet section is arranged at the front end of the jet pipe; the heat exchange pipe is sleeved outside the jet section of the jet pipe; the heat exchange pipe and the jet section form a heat exchange structure; a heat exchange cavity is formed in the heat exchange pipe; a heat exchange inlet and a heat exchange outlet are arranged on the heat exchange pipe; and the heat exchange cavity is communicated with the outside through the heat exchange inlet and the heat exchange outlet. The indirect heat exchange type ice crystal spread-resistant device has a simple structure and can effectively block the quick and reverse spread of ice crystals.

Description

technical field [0001] The invention belongs to the field of ice crystal manufacture, and in particular relates to an indirect heat exchange anti-ice crystal spreader. Background technique [0002] Ice-storage air-conditioning is a user-side management technology that has a significant effect on power grid load shifting peaks and valleys. This technology uses the surplus power at night to turn on the refrigeration unit to make ice, and stores the cold energy in the form of ice. The cold energy is released by melting ice to meet the needs of air conditioner users, so as to avoid or reduce the use of electricity during peak hours, realize the peak shifting of grid load, reduce the contradiction between peak and valley load of grid load, and improve the operation of power plants. Efficiency, and ultimately achieve overall energy saving and emission reduction benefits. [0003] The core of the ice storage air conditioner is the ice making system. The traditional ice storage tec...
