Embodiment Construction

[0063] The patent of the present invention proposes a waste heat ammonia water absorption refrigeration system for fishing boats, which mainly includes an ammonia water absorption ice-making system, a low-temperature water system and an ice storage system.

[0064] An ammonia water absorption refrigeration system for waste heat of a diesel engine used in a fishing boat, the ammonia water absorption refrigeration system mainly includes a rectification generating device 2, a condenser 1, an evaporator 7, an absorber 4, and the like. The flue gas discharged from the diesel engine enters the rectification generator 2 through the flue gas inlet 39, and serves as the main heat source of the system. The ammonia solution in the rectification generator 2 is heated to generate ammonia vapor, and high-concentration ammonia gas is obtained after rectification. The high-concentration ammonia gas enters the condenser 1 and is condensed into ammonia liquid after exchanging heat with cooling w...

Abstract

The invention relates to a fishing-boat diesel-engine residual-heat refrigerating technology. A fishing-boat diesel-engine residual-heat ammonia-water absorption-type refrigerating system mainly comprises an ice-making system, a low-temperature water-making system, a direct cold-supplying system and an ice-storing system, and operating modes mainly comprise an ice-making mode I, a low-temperature water-making mode II, a cold-storing mode III, a direct cold-supplying mode IV and an ice-storing slot cold-supplying mode V, wherein the operating mode V only works when a fishing-boat engine is stopped, the operating modes I, II, III and IV work when the fishing-boat engine operates, and the operating modes I, II, III and IV can be randomly combined as required. In the invention, according to the characteristics of ammonia-water absorption-type refrigeration and fishing-boat working, the problems of ice making, environmental cold supply, low-temperature water making and the like of a fishing boat are solved while a large amount of residual-heat resources are recycled by the fishing-boat diesel-engine residual-heat ammonia-water absorption-type refrigerating system, the working requirements of the fishing boat are met, and the fishing-boat diesel-engine residual-heat ammonia-water absorption-type refrigerating system has quite important significance for improving the production efficiency and improving the working environment of the fishing boat.

Description

technical field [0001] The patent of the present invention relates to a diesel engine waste heat refrigeration system for fishing boats, in particular to the structure and operation mode of a fishing boat using the diesel engine waste heat to perform ammonia water absorption refrigeration system. Background technique [0002] Existing small and medium-sized fishing boats generally do not make ice, and fish preservation and cold storage require a large amount of ice, so fishing boats usually carry a large amount of ice to sea, and the ice they carry will occupy the storage space of the fishing boat, and the amount of ice that can be carried is also limited. In addition, the low-temperature water required for some fish preservation cannot be prepared on general fishing boats. These factors will cause fishing boats to frequently go back and forth between the port and the fishing sea area, consuming a lot of fuel and time, and the economic benefits are not significant.
