Separation heat-pipe type absorbing ice machine used for ship

Abstract

The invention is a quasi-separating hot-tube absorbing ice machine for ships. It adopts fume pipeline to directly heat, the intermediate cooler is welded with the second ammonia tank and connected with an absorbing bed through the ascending and descending segments of the hot tube, the electromagnetic valve is set on the descending segment, the condenser is welded with the first ammonia tank and connected with the absorbing bed, the single-way valve is connected with connecting pipe, the first ammonia tank is connected with ice piece machine, the ice piece machine is connected with the absorbing bed, mass recovery valve is set on the connecting pipe between the condenser and the absorbing bed and between the ice piece machine and the absorbing bed, cold sea water loop adopts a serial mode, the sea water valve and cold sea water pump are set on the cold sea water inlet pipeline, the cold sea water loop is firstly interconnected with the condenser and then with the intermediate cooler and the cold sea water outlet. It adopts mixed adsorbent-ammonia working medium pair, the absorbing bed is cooled by using ammonia as cooling medium, thus able to avoid the corrosion problem and also simplify structure and enhance heat exchange effect.

Description

technical field [0001] The invention relates to a marine adsorption refrigeration system, in particular to a separation heat pipe type marine adsorption ice maker. It belongs to the field of adsorption refrigeration. Background technique [0002] At present, most of the small and medium-sized fishing boats in my country's coastal areas use ice storage as the main method for fresh-keeping, supplemented by mechanical refrigeration. Therefore, fishing boat refrigerators are currently equipment that is urgently needed for small and medium-sized fishing boats, and the research and development is still concentrated on the vapor compression refrigeration method. At the same time, about 30% of the heat of diesel engines on fishing boats is wasted from the exhaust into the atmosphere. If this part of the waste heat can be used to drive the adsorption refrigeration system, it can only recover the waste heat of the exhaust gas to make ice without increasing the fuel consumption of th...

Problems solved by technology

The second way is to use the fresh water of the intermediate heat exchanger to cool, so that a cold water pump needs to be added to the adsorption system, which will inevitably increase the consumption of electricity

In addition, the adsorption bed adopts water cooling as a convective heat transfer method, and its heat transfer effect is relatively limited.
