Vortex direct contact ice device

Abstract

The invention provides a vortex direct contact ice maker, characterized in that: ice making container is connected smoothly of the upper half part of cylindrical flow stabilizing cavity and the lower half part of conic separating cavity, the center of top end cover of the ice making container is equipped with funnel ice slurry outlet and the bottom equipped with cryogen outlet, the top of the flow stabilizing cavity is respectively equipped with pairs of uniformly separated and symmetrically distributed secondary refrigerant and water solution spray nozzles in the tangent direction of the cylinder wall; when making ice slurry, the secondary refrigerant and water solution injected into the flow stabilizing cavity form vortex and fully mix and exchange heat with each other to make a part of water solution turn into ice slurry, and they are respectively separated and discharged under the action of centrifugal force of the vortex and gravity. And the ice maker solves the problem of separation of ice slurry from water solution and secondary refrigerant, avoiding ice jam happening caused by adhesion of ice slurry particles and the problems of large secondary refrigerant dosage caused by carrying secondary refrigerant and ice slurry into ice storage cylinder and of carrying water solution into plate heat exchanger, further improving the efficiency and running stability.

Description

technical field [0001] The invention relates to a dynamic ice slurry producing device, in particular to a vortex direct contact ice making device. Background technique [0002] The application of ice storage technology is one of the important measures to solve the unbalanced power load during the day and night, manage the peak power consumption, and reduce the power load. Store in ice slurry form. When the power consumption is high, the stored cooling capacity is released for use by air-conditioning users, so as to alleviate the peak power consumption contradiction and reduce the cost of air-conditioning users. Therefore, it is the development direction of ice storage technology to develop efficient and stable ice slurry production device. In the prior art, dynamic ice slurry generators include supercooling, scraping, direct contact jetting, and vacuum. But there are still many problems in the preparation process of dynamic ice slurry. Because the scraping type needs to ...

Problems solved by technology

However, similar structures at home and abroad that use the brine to directly contact the injection type to prepare ice slurry, because the brine is brought into the ice slurry and cannot be separated, the amount of brine is too much, and the ice layer, water layer, and brine The layer delamination is not obvious, which leads to a series of problems of ice blockage in the plate heat exchanger and the ice slurry production injection port, which directly leads to the unstable operation of the direct contact ice making device, which affects the quality of the ice slurry and the improvement of the ice making efficiency
