Ammonia water absorption refrigerator used in boat and drove by residual heat of ship engine exhaust

Abstract

The invention is a kind of marine ammonia liquor absorption refrigerator which relates to technology field of refrigeration by excess heat. it is characterized in that making use of ship craft exhausting excess heat to heat generator full use of ammonia liquor; free ammonia and liquor flows into gas-liquid separator all together, the separated free ammonia containing water or moisture is partly purified by dephlegmator and condensates in the condensator; ammonia liquor evaporates in the casing evaporator and produces cold energy, cold free ammonia and marine ammonia which does not evaporate exchange heating the coil subcooler, and enters full liquid bubble absorber under gravity and differential pressure; free ammonia bubble is absorbed by dilute solution of marine ammonia from gas-liquid separator and cooled by solution heat exchanger , dense dilute solution of marine ammonia flows into marine ammonia tank and driven into full liquid generator by solution pump. The effect and benefit of the invention is that making use of excess heat can work under incline, swing and bump; it can save energy and protect environment, the operation cost is low, it is especially fit for refrigeration, ice-making and air- of different shipping.

Description

technical field [0001] The invention belongs to the technical field of waste heat refrigeration, and relates to a marine ammonia water absorption refrigerator driven by exhaust waste heat of a ship engine and capable of operating under conditions of tilting, swinging and bumping. Background technique [0002] The upper part of the generator of the existing ammonia water absorption refrigerator is equipped with a rectification tower, and the concentrated ammonia solution enters from the stripping section of the rectification tower, and flows into the generator from top to bottom relying on gravity, and there is a liquid level in the generator; Membrane absorbers, the performance of these devices deteriorates sharply when they are operated under tilting, swaying, and turbulent conditions, resulting in the inability of existing ammonia water absorption refrigerators to operate under slanting, swaying, and turbulent conditions. Contents of the invention [0003] The object of ...
