The invention provides a multi-evaporation cooling type aqueous ammonia absorption system. The multi-evaporation cooling type aqueous ammonia absorption system comprises a primary seawater condenser, a primary evaporation cooling type absorber, an evaporator and a throttling valve. The primary seawater condenser is connected with the primary evaporation cooling type absorber; the primary evaporation cooling type absorber is connected with a secondary seawater condenser; the secondary seawater condenser is connected with a secondary evaporation cooling type absorber; the secondary evaporation cooling type absorber is connected with a tertiary seawater condenser; and the tertiary seawater condenser is connected with the evaporator. According to the multi-evaporation cooling type aqueous ammonia absorption system, seawater enters the system through an aluminum pipe so as to prevent metal from being corroded by the seawater. In the absorber, a stainless steel material is adopted so as to prevent the metal material from being corroded by aqueous ammonia. The evaporator and the like adopt an in-pipe evaporation manner so that influences on the performance of the device due to the swaying of a boat can be avoided. The absorber adopts a screw hole type liquid distribution technology and the distance between coiled pipes is less than 1 mm, so that the influences on the absorption performance due to the swaying of the boat can be effectively avoided.
Description
technical field [0001] The invention relates to an ammonia water absorption system, in particular to a multiple evaporative cooling type ammonia water absorption system. Background technique [0002] The research on the application of marine adsorption ice-making devices is mainly aimed at offshore fishing. At present, in order to save oil, small and medium-sized fishing boats along the coast are not equipped with refrigerators and go to sea with ice. Take the 804 fishing boat with a fishing capacity of 100 tons as an example. It takes about 15 days to bring 25 tons of ice, 100 yuan per ton of ice, 15 voyages a year, and a yearly cost of about 40,000 yuan. At present, with the depletion of offshore resources, the relocation of fishing grounds, and the shortage of fresh water and diesel resources in islands, the traditional fishing boats go out to sea to bring ice and apply ice to keep fresh. The technology has become increasingly unable to meet the requirements of fishing. ...
