Low-temperature air generator and low-temperature tunnel or low-temperature processing apparatus formed thereby

Abstract

The invention discloses a method for generating low-temperature air and an apparatus thereof, i.e. a low-temperature air generator. A channel consisting of a heat exchanger and an insulation layer has the technical characteristics that pre-processed air is input from an input port of the channel to exchange cold energy with a cold medium or a low-temperature liquid in the heat exchanger in the channel so as to generate low-temperature air which is output from an output port of the channel. The generated low-temperature air provides cold sources for apparatuses or facilities including refrigeration houses, material low-temperature processing and cold treatment, refrigeration houses and the like; a low-temperature tunnel consists of the low-temperature air output by the low-temperature air generator and a material conveying tunnel to carry out pre-cooling (physical change) and cold treatment (chemical change) on materials, so as to realize low-temperature processing of materials by a low-temperature processing apparatus which is formed by combining the low-temperature air and a processing apparatus. The vaporization of the low-temperature liquid is continuous to ensure that the low-temperature air of the low-temperature air generator is continuous; and the materials are continuously lowered to the low temperature through the low-temperature tunnel so as to ensure that the low-temperature processing apparatus continuously processes, which has no precedent that the cold energy is abandoned and recycled to realize the low-temperature processing effect.

Description

technical field The invention relates to a method and equipment for generating low-temperature air, that is, a low-temperature air generator or device for generating low-temperature air. The low-temperature air generated by the low-temperature air provides cold sources for equipment or facilities such as cold storage, low-temperature processing and cold treatment of materials. The low-temperature air output by the low-temperature air generator is combined with the material conveying tunnel (pipe) to form a low-temperature tunnel to pre-cool and cold-treat the material; or to form a low-temperature processing equipment with the processing equipment to realize low-temperature processing of the material; the present invention is also suitable for generating other low-temperature Refrigerants, such as producing low-temperature nitrogen, belong to the technical fields of heat exchange and material refrigeration, freezing, low-temperature processing, and cold treatment.
