Ammonia absorber with solution cooling down absorption segment and silk screen corrugated filler layer

Abstract

The present invention discloses an ammonia absorber with a solution refrigeration absorption section and a silk screen corrugated filling material layer, and relates to an absorber of an ammonia absorption type refrigerator. The present invention comprises a casing, a cooling water cooling absorption section component, and a dilute solution spaying distribution pipe component; a left pipe plate and a right pipe plate are respectively arranged at the left end and the right end of a tube body on the casing; the absorber also comprises a strong solution cooling absorption section component, the two ends of each heat transfer pipe of an upper heat transfer pipe bundle are respectively inserted and welded in the pipe orifices of the left pipe plate and the right pipe plate, an upper pipe bundle inlet cavity and an upper pipe bundle outlet cavity are respectively arranged on the two sides of the right pipe plate, an upper pipe bundle returning cavity is arranged on the left pipe plate, a strong solution inlet pipe is arranged on the upper pipe bundle inlet cavity, a strong solution outlet pipe is arranged on the upper pipe bundle outlet cavity; the silk screen corrugated filling material layer is arranged between each layer of pipes of the spaying distribution pipe, the upper heat transfer pipe bundle and the lower heat transfer pipe bundle. The present invention aims to improve the circulation efficiency of the system and the heat transfer medium efficiency of the absorber, and to improve the effectiveness of the liquid film distribution on the outer surface of a parallel pipe bundle.

Description

technical field [0001] The invention relates to an absorber of an ammonia water absorption type refrigerator, in particular to an absorber of an ammonia water absorption type refrigerator with a solution cooling absorption section and a corrugated wire mesh packing layer. Background technique [0002] Although the ammonia water absorption refrigerator is the earliest artificial refrigeration method that can realize continuous refrigeration, it is generally considered to be a bulky and low-efficiency method, so innovations in compactness and efficiency are required. One way to improve the efficiency of ammonia water absorption refrigeration cycle is to use absorption heat to heat the solution back and forth, and ultimately reduce the consumption of external energy in the generator, which is solution cooling absorption. Another problem to be solved by falling film absorbers of ammonia absorption chillers for fresh-keeping refrigeration of offshore fishing vessels is the effect...
