Problems solved by technology
[0007] However, in the case of adopting a structure in which the absorbing liquid flows as described above, gas such as water vapor formed by boiling the absorbing liquid tends to stay in the header, and this gas acts as flow resistance and hinders the flow of the absorbing liquid in the heat transfer tubes. The problem

The present invention provides an exhaust heat recovery device and an absorption type refrigerator, wherein the exhaust heat recovery device can realize mobility improvement of absorption liquid in a heat exchange tube. The absorption type refrigerator is provided with an exhaust heat recovery device (40) which heats sparse absorption liquid that flows from an absorption device (2) to a high-temperature regeneration device (5) through the exhaust in an exhaust path (17) of the exhaust that is discharged from the high-temperature regeneration device (5), wherein, the exhaust heat recovery device (40) is provided with the following components: a plurality of heat exchange tubes (43) which are configured orthogonally with the flow direction of the exhaust in a heat exchange chamber (40A) that becomes one part of an exhaust path (17); and tube connection boxes (42A,42B) which are equipped at ends of the heat exchange tube (43). Furthermore the exhaust heat recovery device is also provided with a return tube (49) which connects the upper surfaces (42A1,42B1) of the tube connection boxes (42A,42B) with the high-temperature regeneration device (5), and causes the gas which residues in the pipe connection boxes (42A,42B) to return to the high-temperature regeneration device (5).
Description
technical field [0001] The present invention relates to an exhaust gas heat recovery device which uses exhaust gas from a high-temperature regenerator to heat absorption liquid flowing in an absorption liquid pipe, and an absorption refrigerating machine provided with the exhaust gas heat recovery device. Background technique [0002] Conventionally, an absorption refrigerating machine is known, which has a high-temperature regenerator, a low-temperature regenerator, a condenser, an evaporator, and an absorber, which are connected by piping to form circulation paths for an absorption liquid and a refrigerant respectively (for example, refer to Patent Document 1 ). In such an absorption refrigerating machine, in order to utilize the waste heat of the exhaust gas discharged from the high-temperature regenerator, an exhaust gas heat recovery device is provided on the exhaust gas exhaust path. [0003] The exhaust gas heat recovery device generally has a structure in which the ...
