Liquid dehumidification combined vortex tube low-temperature air-flow output device and pulverizing system

Abstract

The invention discloses a liquid dehumidification combined vortex tube low-temperature air-flow output device, which comprises an air intake unit, a drier, a compressor, a reducer, an air storage tank and a vortex tube. The air intake unit conveys gas to be dried into the drier; the compressor compresses the dried gas from the drier; the reducer receives high temperature and high pressure gas from the compressor and gas from a hot end of the vortex tube which are used as heat sources; a liquid storage tank stores dried high pressure gas outputted from the reducer; the vortex tube carries out hydrocyclone separation on high pressure gas from the liquid storage tank; a cold end of the vortex tube outputs low temperature air-flow; and the reducer carries out evaporation and concentration on a dilute desiccant from the drier. The invention also discloses a liquid dehumidification combined vortex tube low-temperature air-flow pulverizing system. Low-grade heat energy self-produced by the system is used as a heat source for concentration reduction of the desiccant. No extra energy is consumed, and dried gas with high dryness is obtained. As low-temperature air-flow is outputted by the refrigeration effect of the vortex tube, energy utilization is more economical and reasonable.

Description

technical field [0001] The invention relates to the technical field of low-temperature pulverization, in particular to a low-temperature air flow output device and a pulverization system of a liquid dehumidification combined with a vortex tube. Background technique [0002] Low-temperature pulverization refers to the process of crushing the material cooled to the embrittlement point into smaller particles or powders under the action of external force. As early as 1948, low-temperature pulverization technology had been industrialized and applied in many fields such as recycling of waste rubber and plastics and processing of food and medicinal materials. The early low-temperature pulverization devices used mechanical pulverization after low-temperature treatment, but because the energy actually used for pulverization in the mechanical pulverization process was very little, the pulverization efficiency was low, it was not energy-saving, and it would affect the quality of materi...

), but this treatment method is not only complicated in the system, but also causes a certain waste of cooling capacity

In addition, due to the limitation of the principle of the freeze-drying device, after passing through the freeze-drying machine, the temperature of the airflow can only be reduced to about 2°C, and an air cooling device needs to be added later to ensure a better effect of the subsequent impact crushing process, which in turn consumes A large amount of electric energy, resulting in a large waste
