Abstract

The invention discloses a concentric-circle sleeve type perpendicular falling film absorber for refrigeration. The concentric-circle sleeve type perpendicular falling film absorber comprises an epoxy resin composite material on the outermost layer, a modified toughening heat-resistant resin on the middle layer and crystalline flake graphite on the innermost layer in a combined manner; the epoxy resin composite material is carbon fiber reinforced epoxy resin and accounts for 41-45% of the total weight of an anticorrosive coating; the modified toughening heat-resistant resin accounts for 35-36% of the total weight of the anticorrosive coating; the crystalline flake graphite accounts for 18-26% of the total weight of the anticorrosive coating. The concentric-circle sleeve type perpendicular falling film absorber for refrigeration, provided by the invention, has the advantages of greatly increasing the falling film area and greatly improving the absorption efficiency.

Description

technical field [0001] The invention relates to a concentric circular sleeve type vertical falling film absorber for refrigeration. Background technique [0002] In developed countries such as the United States and Japan, the matching of vacuum switches and RC absorbers is a relatively common way of use. Due to some particularities of my country's medium-voltage (3-66Kv) power grid, imported RC absorbers and domestically produced RC absorbers produced by foreign standards in the past cannot adapt to the actual situation in my country, and unexplained damage accidents often occur. This has led to the domestic development speed of this product lagging far behind the vacuum switch. [0003] In the past, the capacitors used in the resistance-capacity overvoltage absorber were not "protective capacitors". In fact, they were refitted on the overvoltage protector. Some used multiple or even hundreds of low-voltage capacitors in series and used them as high-voltage capacitors. Zin...
