It should be noted that the relay 5 according to the embodiment of the present invention is a transfer-type relay, the switch 51 of the relay 5 is electrically coupled to the control module 4, the control module 4 is used for controlling the opening and closing of the switch 51, and the movable contact 52 and the normally closed contact 53 of the relay 5 are electrically coupled to the terminals of the engine M, respectively. Wherein, the equivalent circuit between the relay 5 and the engine M is shown in figure 2. When the switch 51 of the relay 5 is in an open state, the movable contact 52 of the relay 5 is attracted to the normally closed contact 53, and the working circuit of the engine M is in a conducting state. When the switch of the relay 5 is in the closed state, the coil 55 with the iron core 54 outputs a corresponding magnetic field to attract the armature 56, the movable contact 52 is attracted with the normally open contact 57, the working circuit of the engine M is forcibly disconnected, and the engine M stops working. Once the switch state of the relay 5 is changed from the closed state to the open state, the armature 56 of the relay 5 pulls the movable contact 52 and the normally closed contact 53 by the restoring force of the spring 58, and at this time, the working circuit of the engine M is again in a conducting state.

When the pressure of the water vapor in the waste heat recovery main body 1 is smaller than a first preset pressure, the safety valve 2 is in a closed state. At this time, the pressure sensor 3 obtains the water vapor pressure information in the waste heat recovery main body 1, and transmits the water vapor pressure information to the control module 4, the control module 4 enables the switch of the relay 5 to be in an open state according to the water vapor pressure information, the movable contact 52 of the relay 5 is attracted with the normally closed contact 53, the working circuit of the engine M is in a conducting state, and the engine M continues to work.
When the water vapor pressure in the waste heat recovery main body 1 exceeds the first preset pressure and does not exceed the second preset pressure, the safety valve 2 is in an open state, the waste heat recovery main body 1 is decompressed, and the water vapor in the waste heat recovery main body 1 is discharged. At this time, the pressure sensor 3 obtains the water vapor pressure information in the waste heat recovery main body 1, and transmits the water vapor pressure information to the control module 4, the control module 4 enables the switch 51 of the relay 5 to be in an open state according to the pressure information, the movable contact 52 of the relay 5 is attracted with the normally closed contact 53, the working circuit of the engine M is in a conducting state, and the engine M continues to work.
When the water vapor pressure in the waste heat recovery main body 1 exceeds a second preset pressure, the safety valve 2 is in an open state to release the pressure of the waste heat recovery main body 1. At this moment, the pressure sensor 3 acquires the water vapor pressure information in the waste heat recovery main body 1, the water vapor pressure information is transmitted to the control module 4, the control module 4 closes the switch of the relay 5 according to the pressure information, the movable contact 52 of the relay 5 is attracted with the normally open contact 57, the working circuit of the engine M is forcibly disconnected, the engine M stops working, the temperature in the waste heat recovery main body 1 is prevented from being continuously increased, the pressure relief of the safety valve 2 is added, the explosion of the waste heat recovery main body 1 due to the overlarge water vapor pressure in the waste heat recovery main body 1 can be effectively prevented, and the cost is greatly saved.
Therefore, when the waste heat recovery device provided by the embodiment of the invention fails and the water vapor pressure in the waste heat recovery main body 1 is between the first preset pressure and the second preset pressure, the safety valve 2 can be used for relieving the pressure of the waste heat recovery main body 1, the water vapor in the waste heat recovery main body 1 is discharged, and the waste heat recovery main body 1 is prevented from exploding; when the pressure in the waste heat recovery main body 1 exceeds the second preset pressure due to the fault, the engine M can be stopped by the cooperation of the control module 4 and the relay 5, the temperature in the waste heat recovery main body 1 is prevented from being continuously raised, the pressure relief of the safety valve 2 is added, the explosion of the waste heat recovery main body 1 due to the overlarge pressure of the internal water vapor can be effectively prevented, and the cost of the waste heat recovery of the engine M is greatly saved.
In an embodiment of the present invention, the waste heat recovery apparatus further includes: a signal transmitting module 6 electrically coupled to the control module 4; when the water vapor pressure in the waste heat recovery main body 1 exceeds a first preset pressure or a second preset pressure, the control module 4 is further used for sending an alarm signal through the signal sending module 6.

In order to facilitate the signal sending module 6 to send an alarm signal to the terminal, in the embodiment of the present invention, the signal sending module 6 is a wireless signal sending module. By so doing, it is possible to eliminate the need for connecting signal transmission wires between the signal transmission module 6 and the terminal.
In the embodiment of the present invention, the safety valve 2 is a mechanical safety valve. Through so setting up, not only reducible waste heat recovery device's preparation cost still does benefit to the installation of relief valve 2.

Through so setting up, can effectively prevent that waste heat recovery main part 1 from exploding because of inside water vapor pressure is too big, can prolong waste heat recovery main part 1's life.
An example is given in the embodiment of the present invention with respect to the structure of the waste heat recovery main body 1, as shown in fig. 3, the waste heat recovery main body 1 includes: an outer box body 11 and an inner box body 12 positioned in the outer box body 11; the outer box body 11 is provided with a liquid inlet 11a and a liquid outlet 11b, and the safety valve 2 and the pressure sensor 3 are both arranged on the outer box body 11 (see the attached figure 1); the inner casing 12 has an intake port 12a and an exhaust port 12b, both the intake port 12a and the exhaust port 12b extend to the outside of the outer casing 11, and the intake port 12a communicates with the outlet of the engine M.
It will be appreciated that the liquid inlet 11a of the outer case 11 is communicated with a circulating water source.
With the above arrangement, when high-temperature gas (700 to 800 ℃) in the engine M flows into the inner case 12 of the waste heat recovery main body 1 through the outlet of the engine M, heat exchange is performed with the condensed water in the outer case 11.
