Gas direct contact type ice slurry preparation device with precooling sleeve

Abstract

The invention provides a device capable of realizing high-efficiency preparation of ice slurry, and provides the improvement thereof in the industrial production. The device adopts a gas direct contact method; and on this basis, a coiled tube type precooling sleeve and a nozzle gas transmission auxiliary heat exchange device are additionally arranged to largely enhance the ice slurry preparation effect and to improve the preparation efficiency. The precooling sleeve is formed by coiling a copper tube around an ice slurry preparation device; when gas flows through the coiled tube type copper tube, solution can be precooled firstly, and the stop time of the gas in the device is prolonged, so that the whole heat exchange efficiency is improved; and a nozzle device prolongs the stop time of the gas in the device to increase the heat exchange area between the gas and the solution. In addition, a vacuum insulation measure is added, and a vacuum thermal insulation principle is used for vacuumizing the middle part of two layers of an outer barrel of the device, so that the cooling capacity loss of secondary refrigerant gas to the environment when flowing in the device is reduced. Through the improvement, experiments and industrial production equipment are simplified and optimized to facilitate the construction and the later maintenance.

Description

technical field [0001] The present invention includes a device system and method capable of rapidly producing ice slurry, and the present invention also relates to the application of the device to quickly produce ice slurry in actual production and life. Background technique [0002] In some large and medium-sized cities, air-conditioning power consumption accounts for more than 20% of peak power consumption. However, the peak-to-valley load difference of the power grid is as high as 40%, resulting in a large idle of power generation resources and a great waste of power resources at night. Ice storage technology is a kind of reserve for energy. Its principle is to use the cheaper low-power electricity at night to make ice, store the cold energy, and release the latent heat of phase change when the ice melts at the peak of electricity consumption. Refrigeration provides air conditioning and other refrigeration services. All countries are now encouraging the use of cold stora...

Problems solved by technology

Now all countries are encouraging the use of cold storage air conditioners. It can be seen that ice storage has become a very important science and technology, but there is still a lot of room for improvement in this technology

[0003] The existing technology is to stack many balls in a cylindrical cold storage tank, so that the brine flows through the balls and exchanges heat, and the condensation of ice balls is a very complicated heat transfer problem.
