Ice slurry concentration device capable of realizing stepless concentration regulation

Abstract

The invention discloses an ice slurry concentration device capable of stepless concentration regulation. The device comprises a circular truncated cone shell used for storing ice slurry, wherein the shell for storing ice slurry is shaped as a circular truncated cone the upper end of which is small and the lower end of which is big, a reducing shape is formed and the ice slurry concentration effect is improved; the axial cross section of the circular truncated cone shell is trapezoidal; the central axis of the top end of the circular truncated cone shell is connected with an upper end exit section, the central axis of the bottom end of the circular truncated cone shell is connected with a lower end exit section; the middle-bottom part of the circular truncated cone shell surface is connected with an entrance section; the upper end exit section, the lower end exit section and the entrance section are respectively provided with a regulation valve; by controlling pipe openness degree, stepless regulation of ice slurry concentration can be realized. While the effective improvement of ice slurry concentration is guaranteed, the slurry concentration can reach 20%-30%, stepless regulation of ice slurry concentration can be realized and ice slurry of arbitrary concentration can be produced.

Description

technical field [0001] The invention relates to an ice slurry thickening device for increasing the concentration of ice slurry. Background technique [0002] Existing large and medium-sized air-conditioning systems or cooling systems have a huge demand for cold delivery. When conventional cold water is used as the cooling medium, the pump power often accounts for 20%-60% of the total power consumption. Therefore, high-density latent heat delivery technology become a research hotspot. Ice slurry has a large cooling density, excellent hydrodynamic performance, and environmental friendliness, and is an ideal high-density cooling agent. According to relevant studies, the optimal transport concentration of ice slurry is 20%-30%, but the concentration of ice slurry obtained by conventional ice slurry production technology generally does not exceed 5%. Therefore, the ice slurry thickening device has become an effective means to obtain high-concentration cooling medium, and it is ...
