Abstract

The invention discloses a mixed vaporizer internal combustion waste heat utilization system which comprises a mixed vaporizer. A high temperature liquid inlet of the mixed vaporizer is communicated with an internal combustion engine coolant gallery fluid outlet through a liquid circulation booster pump. A low temperature liquid outlet of the mixed vaporizer is communicated with an internal combustion engine coolant gallery fluid inlet through a throttling control valve or a throttling structure. The mixed vaporizer is provided with a vapor outlet. A liquid area of the mixed vaporizer is provided with a working medium inlet. The loading capacity of the mixed vaporizer is higher than 0.3MPa. The mixed vaporizer internal combustion waste heat utilization system is simple in structure and low in manufacturing cost.

Example Embodiment

[0051] Example 1

[0052] Such as figure 1 The shown hybrid vaporization internal combustion waste heat utilization system includes a hybrid vaporizer 1. The high temperature liquid inlet of the hybrid vaporizer 1 is in communication with the fluid outlet of the cooling water passage of an internal combustion engine via a liquid circulation pressurizing pump 52, and the low temperature liquid of the hybrid vaporizer 1 The outlet is communicated with the fluid inlet of the cooling water channel of the internal combustion engine through the throttle control valve 8. The hybrid vaporizer 1 is provided with a steam outlet 12, and the liquid zone of the hybrid vaporizer 1 is provided with a working fluid inlet 11, the hybrid vaporizer The pressure capacity of 1 is greater than 0.3MPa.

Example Embodiment

[0053] Example 2

[0054] Such as figure 2 The difference of embodiment 1 of the mixed vaporization internal combustion waste heat utilization system shown is:

[0055] The throttle control valve 8 is cancelled, a throttle structure 81 is set at the same position, and the working fluid inlet 11 is further connected with the liquid outlet of the liquid pump 5, and the steam outlet 12 is connected with the work mechanism.

[0056] In this embodiment, the work mechanism is specifically set as a turbine 6. As a transformable embodiment, the work mechanism may also be set as other forms of work mechanism, such as a cylinder-piston mechanism.

[0057] As an alternative embodiment, the work mechanism may not be provided.

Example Embodiment

[0058] Example 3

[0059] Such as image 3 In the hybrid vaporization internal combustion waste heat utilization system shown in Example 1, the hybrid vaporization internal combustion waste heat utilization system further includes an exhaust heat exchanger 2, and the operation of the heated fluid passage of the exhaust heat exchanger 2 The medium outlet is in communication with the working medium inlet of the auxiliary work mechanism, the working medium inlet of the heated fluid channel of the exhaust heat exchanger 2 is in communication with the liquid outlet of the auxiliary liquid pump 51, and the working medium inlet 11 is connected to the liquid pump 5 The liquid outlet is in communication, and the steam outlet 12 is in communication with the work mechanism.

[0060] In this embodiment, the liquid pumped by the auxiliary liquid pump 51 into the heated fluid channel of the exhaust heat exchanger 2 is vaporized in the exhaust heat exchanger 2 and then enters the auxiliary work mechanism to push The auxiliary work mechanism outputs power.

[0061] In this embodiment, the work mechanism and the auxiliary work mechanism are specifically set as turbine 6. As a transformable embodiment, the work mechanism and/or the auxiliary work mechanism can also be set to other forms of work Mechanisms, such as cylinder-piston mechanisms.

[0062] As an alternative embodiment, the work mechanism may not be provided.
