[0032] See also Figure 1—3 shows an energy-saving and environmentally friendly device for recycling high-temperature exhaust gas from a generator, comprising a plurality of fuel oil / gas generator sets and a plurality of steam generator sets. In the present application, the fuel oil / gas generator sets comprise a first fuel oil / gas generator set 10 and a second fuel oil / gas generator set 11, and the steam generator sets comprise a first steam generator set 12 and a second steam generator set 13. Of course, the number of fuel oil / gas generator sets and steam generator sets can be three, four or more. In the implementation of the present application, two units are used for illustration.

[0033] The exhaust pipes of the first fuel / gas generator set 10 and the second fuel / gas generator set 11 are respectively connected to exhaust gas treatment devices, and the high-temperature exhaust gas discharged from the fuel / gas generator set enters the exhaust gas treatment device for filtration and heat exchange; the exhaust gas treatment device is located between the fuel / gas generator set and the steam generator set, that is, the medium after heat exchange in the exhaust gas treatment device is transported to the steam generator set as a heat source for the steam generator set, thereby reusing the heat in the high-temperature exhaust gas.

[0034] Among them, the exhaust gas treatment device includes a particulate filter 14, a first water storage chamber 15, a second water storage chamber 16, a first exhaust pipe 17, and a second exhaust pipe 18. The tail gas pipes of the first fuel / gas generator set 10 and the second fuel / gas generator set 11 are connected in parallel with the inlet end of the particulate filter 14, and the high-temperature exhaust gas can be discharged into the exhaust gas treatment device, and an exhaust valve 19 is installed on the tail gas pipe of each fuel / gas generator set to switch the high-temperature exhaust gas discharged by the first fuel / gas generator set 10 or the second fuel / gas generator set 11 or the two fuel / gas generator sets to be sent to the exhaust gas treatment device.

[0035] A first heat exchange component 20 for performing heat exchange with the water in the first water storage chamber 15 is arranged in the first water storage chamber 15, and a second heat exchange component 21 for performing heat exchange with the water in the second water storage chamber is arranged in the second water storage chamber 16; the heat in the high-temperature exhaust gas is exchanged to the water in the water storage chamber through the heat exchange component, so that the temperature of the water in the water storage chamber rises, and the high-temperature exhaust gas is discharged after being cooled.

[0036] The connection mode of the heat exchange components is specifically as follows: the inlet end of the first heat exchange component 20 is connected to the outlet end of the particulate filter 14, the outlet end of the first heat exchange component 20 is connected to the first exhaust pipe 17, and the first exhaust pipe 17 is equipped with a first exhaust valve 22; the inlet end of the second heat exchange component 21 is connected to the outlet end of the first heat exchange component 20, the outlet end of the second heat exchange component 21 is connected to the second exhaust pipe 18, and the second exhaust valve 23 is equipped on the second exhaust pipe 18; the treated high-temperature exhaust gas can be discharged in the following ways, one is: open the first exhaust valve 22, close the second exhaust valve 23, and the high-temperature exhaust gas is discharged from the first exhaust pipe 17, at this time, the heat exchange of the high-temperature exhaust gas is mainly concentrated in the first heat exchange component 20; the second is: close the first exhaust valve 22, open the second exhaust valve 23, and the high-temperature exhaust gas is discharged from the second exhaust pipe 18, at this time, the first heat exchange component 20 and the second heat exchange component 21 form a series mode, and respectively exchange heat with the water in their respective water storage chambers.

[0037] Among them, the first water storage chamber 15 is connected to a first water outlet pipe 24, and the second water storage chamber 16 is connected to a second water outlet pipe 25. The first water outlet pipe 24 and the second water outlet pipe 25 are connected to a water outlet main pipe 26, and the first water outlet pipe 24 and the second water outlet pipe 25 are respectively equipped with water outlet valves 27, and the water outlet main pipe 26 is equipped with a water pump 28; when it is necessary to take water from the first water storage chamber 15, the water outlet valve 27 on the first water outlet pipe 24 is opened and the water outlet valve 27 on the second water outlet pipe 25 is closed. When it is necessary to take water from the first water storage chamber 15 and the second water storage chamber 16 at the same time, the water outlet valves 27 on the first water outlet pipe 24 and the second water outlet pipe 25 are opened at the same time.

[0038] Each steam generator set includes an evaporator 29 and a steam generator 30. The secondary side of the evaporator 29 is connected to the steam end of the steam generator; the outlet water main pipe 26 is connected to the primary side of the evaporator 29 in each steam generator set; and a switching valve 31 is installed between the primary side of each evaporator 29 and the outlet water main pipe 26. After heat exchange with the high-temperature exhaust gas, the water with increased temperature enters the evaporator 29, exchanges heat with the fluid medium on the secondary side of the evaporator 29 to form a gaseous state, and enters the steam generator as the power generation power of the steam generator; by switching the switching valve 31, the working state of the first steam generator set 12 and the second steam generator set 13 can be switched as needed. For example, when the first steam generator set 12 (the second steam generator set 13) needs to be used for work, the switching valve 31 corresponding to the first steam generator set 12 (the second steam generator set 13) can be opened, and the switching valves 31 can also be opened at the same time, so that multiple steam generator sets work at the same time.

[0039] It also includes a return water main pipe 32 connected to the primary side of the evaporator 29 in each steam generator set, which is used to collect the return water passing through the primary side of the evaporator 29. The return water main pipe 32 is connected to a first return water pipe 33 and a second return water pipe 34. The first return water pipe 33 is connected to the bottom of the first water storage chamber 15, and the second return water pipe 34 is connected to the bottom of the second water storage chamber 16. Return water valves 35 are respectively installed on the first return water pipe 33 and the second return water pipe 34 to control the flow direction of the return water.

[0040] In some implementations, each steam generator set also includes a condenser 36 and a working fluid pump 37. After the fluid medium in the steam generator does work, it enters the condenser 36 to condense into a liquid state, and then is transported by the working fluid pump 37 to enter the evaporator 29 again to form a gas state, and then enters the steam generator, and the cycle continues.

[0041] In some implementations, the first water storage chamber 15 and the second water storage chamber 16 are respectively formed in two water tanks, and the two water tanks are arranged independently of each other to increase the flexibility of the water tank arrangement.

[0042] In some implementations, such as in this application Figure 2 As shown in the figure, the first water storage chamber 15 and the second water storage chamber 16 are formed in a water tank, and a partition plate 38 is arranged vertically in the water tank, and the partition plate 38 extends from the bottom of the water tank. Specifically, the outer walls of the partition plate 38 on both sides are in contact with the inner wall of the water tank, the bottom wall of the partition plate 38 is in contact with the bottom wall in the water tank, and the top wall of the partition plate 38 is in contact with the inner wall of the cover plate of the water tank, so that the water tank body is divided into two independent chambers arranged on the left and right by the partition plate 38, and the independent chamber on the left side serves as the first water storage chamber 15, and the independent chamber on the right side serves as the second water storage chamber 16. In the specific implementation, there are connecting blocks 39 on both sides of the bottom end of the partition plate 38, and the connecting blocks 39 are fixedly assembled to the bottom wall in the water tank by screws, and slots can be opened on both sides of the water tank and the inner wall of the cover plate for the insertion of the other ends of the partition plate 38.

[0043] In some implementations, water distribution plates 40 are respectively provided at the bottom of the first water storage chamber 15 and the second water storage chamber 16, and the water distribution plates 40 divide the respective water storage chambers into an upper heat exchange chamber and a lower water distribution chamber. The heat exchange component is in the upper heat exchange chamber, and the return water pipe is connected to the lower water distribution chamber; a water distribution hole 41 connecting the heat exchange chamber and the lower water distribution chamber is opened on the water distribution plate 40; the water distribution hole 41 transports the water in the lower water distribution chamber at an angle toward the upper heat exchange chamber, thereby making the water in the lower water distribution chamber flow toward the upper heat exchange chamber, thereby increasing the fluidity of the water in the upper heat exchange chamber and accelerating the heat exchange efficiency between the heat exchange component and the water.

[0044] In some implementations, the water distribution holes 41 are distributed on the periphery of the water distribution plate 40. The water distribution holes 41 are arranged obliquely toward the inner wall of the upper heat exchange chamber. After the water flow collides with the inner wall of the upper heat exchange chamber, it changes to a different flow direction, thereby increasing the multi-directionality of the water flow; the aperture of the water distribution hole 41 connected to the upper heat exchange chamber is smaller than the aperture of the water distribution hole 41 connected to the lower water distribution chamber. By setting the water distribution hole 41 with a larger diameter at the bottom and a smaller diameter at the top, the speed of the water flow from the lower water distribution chamber into the upper heat exchange chamber can be increased, further enhancing the water flowability in the upper heat exchanger. The water distribution plate 40 is provided with mounting holes 42 around it, and a bearing block 43 is fixedly provided on the inner wall of the bottom of the water tank. The bearing block 43 is fixedly connected to the water distribution plate 40 by bolts passing through the mounting holes 42.

[0045] In some implementations, the first heat exchange component 20 and the second heat exchange component 21 use heat exchange pipes, which are arranged in a circuitous or coiled manner in the corresponding water storage chamber. Through this structure, the contact area between the heat exchange component and the water in the heat exchange cavity is increased, which correspondingly increases the heat exchange area and improves the heat exchange efficiency.

[0046] In some implementations, such as when the heat exchange pipe is arranged in a circuitous manner, the entire heat exchange pipe can be arranged in a surrounding manner close to the inner circumference of the upper heat exchange chamber, and the water outlet pipe is arranged in the middle position of the upper heat exchange chamber to obtain water intake at a stable temperature.

[0047] In some implementations, auxiliary electric heaters are respectively provided in the first water storage chamber 15 and the second water storage chamber 16, and the auxiliary electric heaters are powered by the electricity generated by the device or / and the power grid or / and the photovoltaic power generation system. The auxiliary electric heater can be arranged in the lower water distribution cavity to heat the water returning to the water tank to increase the basic water temperature returning to the upper heat exchange cavity. The electricity generated by the device can be used by the electrical equipment at the power end 45, and the remaining electricity can be incorporated into the power grid 46 for use.

[0048] In some implementations, a connecting component is provided between the first water storage chamber 15 and the second water storage chamber 16, so that when the liquid level in the first water storage chamber 15 is higher than the liquid level in the second water storage chamber 16, the water in the second water storage chamber 16 flows to the first water storage chamber 15, or when the liquid level in the second water storage chamber 16 is higher than the liquid level in the first water storage chamber 15, the water in the second water storage chamber 16 flows to the first water storage chamber 15. For example, when two water tanks are arranged independently to form the first water storage chamber 15 and the second water storage chamber 16, the connecting component may be a connecting pipe, and the connecting pipe connects the upper parts of the two water tanks; for example, when the first water storage chamber 15 and the second water storage chamber 16 are formed in one water tank through a partition plate 38, the connecting component may be a connecting port 44 opened at the upper part of the partition plate 38, so as to balance the water levels in the two water storage chambers.
