A flue gas hot water type lithium bromide heat exchange system

Abstract

The invention discloses a flue gas hot water type lithium bromide heat exchange system, comprising an internal combustion engine and a lithium bromide heat exchange device, the lithium bromide heat exchange device is arranged on the flue gas pipeline of the internal combustion engine, and the lithium bromide heat exchange device is connected to the internal combustion engine through a heat source water pipeline, wherein The lithium bromide heat exchange device includes a lithium bromide unit, a water-water heat exchanger and a flue gas-water heat exchanger. The lithium bromide unit and the flue gas-water heat exchanger are all set on the flue gas pipeline. Both the heat exchanger and the flue gas-water heat exchanger are connected to the internal combustion engine through the heat source water pipeline. The invention integrates the flue gas-water heat exchanger and the water-water heat exchanger with the lithium bromide unit to jointly exchange heat between the flue gas of the internal combustion engine and the waste heat of high-temperature cooling water, and has the advantages of simple structure, high heat exchange efficiency, and less land occupation , the advantages of high security, and the value of popularization and application.

Description

technical field [0001] The invention relates to a lithium bromide heat exchange system, in particular to a flue gas hot water type lithium bromide heat exchange system, which belongs to the technical field of internal combustion engine lithium bromide heat exchange. Background technique [0002] At present, lithium bromide heat exchanger units are mainly used to recover the waste heat of internal combustion engine flue gas and high-temperature cooling water. The lithium bromide heat exchanger unit has a simple structure, low requirements for the installation foundation, no special machine base, and it is small in size, small in floor space, easy to manufacture and control, low in maintenance costs, and very safe in operation. [0003] In the existing internal combustion engine lithium bromide heat exchange system, the heat exchanger is set independently from the lithium bromide unit, that is, the lithium bromide unit and the heat exchanger both perform heat exchange on the i...

Problems solved by technology

[0003] In the existing internal combustion engine lithium bromide heat exchange system, the heat exchanger is set independently from the lithium bromide unit, that is, the lithium bromide unit and the heat exchanger both perform heat exchange on the internal combustion engine separately to absorb the waste heat of the internal combustion engine flue gas and high-temperature cooling water , which has the problems of insufficient waste heat recovery from internal combustion engine flue gas and low recovery efficiency, and the system occupies a large area
