The invention relates to an ammonium hydroxide absorption refrigerating machine which is characterized in that a flooded vertical generator is adopted, and an upper smoke box and a lower smoke box which are communicated with each other through an inner smoke tube of a generator barrel body are arranged at the upper part and the lower part of the flooded vertical generator; a spring push-pull plate is arranged in the upper smoke box; a spring is mounted in each heat exchange smoke tube and is made of high-temperature-resistant materials, and the surface of the spring is subjected to oil-free treatment; the upper end of the spring is fixed on a spring fixing pin of the spring push-pull plate, and the lower end of the spring is free and not fixed; a push-pull transmission shaft is arranged on the spring push-pull plate and penetrates through a sealing shaft sleeve arranged on the cover plate of the upper smoke box to be connected with an electric eccentric shaft transmission mechanism; a spring push-pull plate fixing shaft is mounted at the lower part of the cover plate of the upper smoke box, and the electric eccentric shaft transmission mechanism drives the spring push-pull plate to do vertical reciprocating motion along the spring push-pull plate fixing shaft. The ammonium hydroxide absorption refrigerating machine can operate for a long term without oil accumulation and influence on heat exchange, and has the advantages of energy conservation, environmental protection and low operation cost.
Description
[0001] This application is a divisional application of the Chinese invention patent application with the application date of September 6, 2012, the application number being 2012103267000, and the name of the Chinese invention patent application for ammonia absorption refrigerator and full liquid vertical generator degreasing device. Technical field [0002] An ammonia absorption refrigerator driven by exhaust heat of an enameled wire oven relates to the technical field of waste heat refrigeration, and can operate for a long time without oil accumulation. Background technique [0003] The existing ammonia absorption refrigerators cannot solve the problem of oil accumulation in the heat exchange tubes of the generator, which causes the heat exchange efficiency of the generator to drop greatly after the unit runs for a period of time, and the final unit cannot operate normally. Summary of the invention [0004] The object of the present invention is to provide an ammonia absorption ref...
