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 comprises high pressure generator 2, first low pressure generator (13), second low pressure generator 18, first condenser 12, second condenser 15, evaporator 14, absorber 16, generator pump 17, First heat exchanger 1, second 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, diesel engine cylinder liner cooling chamber 8 , cylinder liner cooling water pump 9, diesel engine, exhaust manifold and intake manifold, as well as connecting pipelines 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 second low-pressure generator 18 through a steam pipeline. A throttling valve is arranged at the inlet of the steam heat exchange tube bundle, and the outlet o...

specific Embodiment approach 2

[0032] This embodiment is different from specific embodiment one in that it combines the first low-pressure generator (13) and the second low-pressure generator 18 into a low-pressure generator 21, and the first condenser 12 and the second condenser 15 are combined It is a condenser 20, and the steam outlet of the high-pressure generator 2 is connected to the inlet of the steam heat exchange tube bank in the low-pressure generator 21 through a steam pipeline, and the steam heat exchange tube bank and the low-temperature heat source water heat exchange tube bank are jointly arranged in the same low-pressure generator 21 , and in the form of a cross arrangement. The high-temperature steam generated by the high-pressure generator 2 is introduced into the low-pressure generator 21 through pipelines, and together with the low-temperature heat source water, the dilute solution in the low-pressure generator 21 is heated. Other components and connections are the same as those in the f...

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 refrigerating device, in particular to a lithium bromide absorption refrigerating device driven by waste heat of a cruise diesel engine. Background technique [0002] The refrigeration system design of the cabin is essential in cruise ships. At present, the compression refrigeration device is the mainstream product of the marine refrigeration device, but it consumes a large amount of electric energy and seriously consumes the power generation of the main engine of the ship. The marine air-conditioning waste heat absorption refrigeration technology is driven by the waste heat of the diesel engine, which effectively avoids the shortcomings of the compression refrigeration device. At the same time, taking the Wartsila 12V46ME medium-speed diesel engine (this main engine is commonly used in "Ocean" series cruise ships) as an example, the effective work only accounts for 50.16% of the heat released by f...
