Large-scale refrigeration-type drying machine with stepless energy adjustment

Abstract

The invention discloses a large-scale refrigeration-type drying machine with stepless energy adjustment. The machine comprises a pre-cooling heat regenerator, one end of the precooling heat regenerator is fixedly connected with a first connecting pipe; a gas-liquid separator is fixedly connected to one end, far away from the pre-cooling heat regenerator, of the first connecting pipe; the end, awayfrom the first connecting pipe, of the outer side of the gas-liquid separator is fixedly connected with a second connecting pipe; the end, away from the first connecting pipe, of the outer side of the precooling heat regenerator is fixedly connected with a third connecting pipe. The end, away from the precooling regenerator, of the third connecting pipe is fixedly connected with an evaporator; the beneficial effects of the machine are that the device achieves the following beneficial effects: the device is convenient to use; a refrigeration compressor is compact in structure and high in practicability, the optimal adjustment proportion which cannot be achieved by a conventional refrigeration compressor with three-section and four-section capacity adjustment can be achieved by arranging the refrigeration compressor in a stepless energy adjustment mode, and meanwhile the service life of the refrigeration compressor is longer and the refrigeration compressor is more suitable for occasions with large load changes by arranging the multiple protection functions.

Description

technical field [0001] The invention relates to a freeze dryer, in particular to a large freeze dryer with stepless energy regulation, and belongs to the technical field of drying equipment. Background technique [0002] In the existing life, whether it is industrial or civil, the application of compressed air is becoming more and more extensive, and the compressed air purification technology is becoming more and more advanced. At present, most of the large freeze dryers on the market use three-stage or four-stage capacity Adjusted refrigeration compressor, this form can not meet the change of load, and load from 50% capacity to 100% capacity in a short time. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a large-scale refrigerated dryer with stepless energy regulation. [0004] In order to solve the problems of the technologies described above, the present invention provides t...
