Problems solved by technology

In order to improve the economy of the device and achieve a lower evaporation temperature, fractional condensation and rectification equipment must be used to increase the concentration of ammonia, which not only increases the complexity of the system, but also makes the ammonia absorption refrigeration system too large
(2) The ship is turbulent at sea, and the traditional ammonia water absorption refrigerator generally adopts falling film evaporation technology, so that the falling film absorption performance is greatly affected by the ship's turbulence
This patent uses a rectification tower, which makes the whole system larger in volume, which is not conducive to the miniaturization of the system; at the same time, the use of reflux ammonia liquid for ammonia gas purification, rectification heat is not fully utilized, making the performance coefficient of the system Low; the absorber has a natural liquid surface, and the absorption performance will be affected by the pitching and rolling of the ship

Abstract

The invention relates to an ammonia water absorption refrigerating machine driven by marine exhaust, belonging to the technical field of refrigeration. The ammonia water absorption refrigerating machine comprises a generator, a backheating process component, a cooling process component, a subcooler and an evaporator, wherein the backheating process component is respectively connected with the generator and the cooling process component; the cooling process component is connected with the subcooler; and the subcooler is connected with the evaporator. The invention simplifies a rectifying device and enables the structure of an integral system to be compact, thereby being beneficial to miniaturized production; an absorber enables ammonia and ammonia water to flow in parallel-connected slim tubes by utilizing the channel flow characteristics of vapor and liquid inside a pipeline, therefore the absorption property of the system is not influenced by marine bumpiness and wobble; the generator enables the ammonia water to boil in a plurality of parallel-connected slim tubes by utilizing the boiling inside the slim tubes, and no welding point exists in the generator, therefore the reliability of the generator can be effectively enhanced.

Description

technical field [0001] The invention relates to a device in the technical field of refrigeration, in particular to an ammonia water absorption refrigerator driven by exhaust gas from a ship. Background technique [0002] With the adjustment of the ship's operation mode, the operation voyage is getting farther and the time is longer. People's requirements for energy saving and environmental protection of ship operation are getting higher and higher. Especially for fishing boats, the ice-carrying fresh-keeping method of traditional fishing boats has become less and less suitable for the fresh-keeping requirements of existing fishery production. Therefore, it is inevitable to widely promote the application of new refrigeration technologies on ships. [0003] The existing refrigeration technologies on ships mainly include compression refrigeration technology and absorption refrigeration technology. Compression refrigeration system units mainly include refrigeration compressors...
