Problems solved by technology

Therefore, directly passing the flue gas into the generator will cause certain safety risks to the overall lithium bromide absorption refrigeration device and even the normal ocean navigation of the cruise ship.
Therefore, this waste heat utilization scheme for automobile engines is not suitable for cruise ships

specific Embodiment approach 1

[0022] This embodiment includes high pressure generator 2, low pressure generator 13, low pressure generator 18, condenser 12, condenser 15, evaporator 14, absorber 16, generator pump 17, heat exchanger 1, heat exchanger 19, Flue gas heat exchanger 5, high temperature heat source water pump 4, high temperature heat source water tank 3, turbocharger 6, two-stage intercooler, liner cooling water tank 8, liner cooling water pump 9, diesel engine, exhaust manifold and intake Gas header and connecting pipes and throttle valves of various components.

[0023] The specific implementation of this program is as follows:

[0024] The steam outlet of the high-pressure generator 2 is connected to the inlet of the steam heat exchange tube bundle in the low-pressure generator 18 through a steam pipeline. A throttle valve is provided at the inlet of the steam heat exchange tube bundle. The outlet of the steam heat exchange tube bundle is connected to the condenser 15 through a refrigerant water p...

specific Embodiment approach 2

[0032] The difference between this embodiment and the first embodiment is that it combines the low-pressure generator 13 and the low-pressure generator 18 into one low-pressure generator 21, and the condenser 12 and the condenser 15 are combined into one condenser 20, and the high-pressure generator 2 The steam outlet is connected through the steam pipeline and the inlet of the steam heat exchange tube bundle in the low pressure generator 21. The steam heat exchange tube bundle and the low temperature heat source water heat exchange tube bundle are arranged together in the same low pressure generator 21 in a cross arrangement. The high-temperature steam generated by the high-pressure generator 2 is introduced into the low-pressure generator 21 through a pipeline, and heats the dilute solution in the low-pressure generator 21 together with the low-temperature heat source water. Other components and connection relationships are the same as in the first embodiment.

Abstract

The invention aims to provide a lithium bromide absorption type refrigerating device driven by waste heat of a cruise ship diesel engine. The device takes water as a refrigerant and takes a lithium bromide solution as an absorbent, and mainly comprises a high-pressure generator, low-pressure generators, a condenser, an evaporator, an absorber, a generator pump, heat exchangers, a flue gas heat exchanger, a high-temperature heat source water pump, a high-temperature heat source water tank, a turbocharger, a two-section intercooler, a cylinder sleeve cooling water tank, a cylinder sleeve coolingwater pump, a diesel engine, an exhaust air collecting pipe, an air inlet collecting pipe, and connecting pipelines of all components and a throttling valve and the like. According to the device, thewaste heat of the cruise ship diesel engine can be efficiently utilized, so that the refrigeration requirements under different working conditions and environments are met.

Description

Technical field [0001] The invention relates to a lithium bromide absorption refrigeration device, in particular to a lithium bromide absorption refrigeration device driven by the waste heat of a cruise ship diesel engine. Background technique [0002] The design of the refrigeration system in the cabin of a cruise ship is essential. At present, the compression refrigeration device is the mainstream product of the marine refrigeration device, but it consumes a large amount of electric power and seriously consumes the power generation of the main engine of the ship. The marine air conditioning waste heat absorption refrigeration technology uses the waste heat of the diesel engine to drive, which effectively avoids the deficiencies of the compression refrigeration device. At the same time, take the Wärtsilä 12V46ME medium-speed diesel engine (the main engine is commonly found in the "Ocean" series of cruise ships) as an example, the effective work only accounts for 50.16% of the h...
