[0028] Referring to Figure 1 As shown, the embodiment of this application provides a flue gas recovery type cooling system, including:

[0029] Flue gas type lithium bromide ice water machine 1;

[0030] An incinerator 2 connected to the flue gas type lithium bromide ice water machine 1, used to provide heat source for the flue gas type lithium bromide ice water machine 1;

[0031] The flue gas type lithium bromide ice water machine 1 is also connected to the smoke exhaust part 3, used to discharge the flue gas;

[0032] A circulation pipeline 4 connected to the flue gas type lithium bromide ice water machine 1, the circulation pipeline 4 includes a liquid inlet part 41 and a liquid outlet part 42, and both the liquid inlet part 41 and the liquid outlet part 42 are connected to the flue gas type lithium bromide ice water machine 1;

[0033] Among them, the liquid outlet part 42 and the liquid inlet part 41 are both connected to the cooling steel belt 5. The cooling steel belt 5 has a spraying part 51 and a liquid return part 52. The liquid outlet part 42 is connected to the spraying part 51, and the liquid inlet part 41 is connected to the liquid return part 52, which is used to form a coolant circuit to cool down the coolant.

[0034] According to Figure 1 , those skilled in the art can set that a flue gas type lithium bromide ice water machine 1 is installed between the incinerator 2 and the smoke exhaust part 3. The coolant in the cooling steel belt 5 is connected to the flue gas type lithium bromide ice water machine 1 through the circulation pipeline 4.

[0035] It can be understood that high-temperature flue gas can be discharged from the incinerator 2, and the flue gas will be directly discharged into the flue gas type lithium bromide ice water machine 1. The high-temperature flue gas can be directly used as the heat source of the flue gas type lithium bromide ice water machine 1 unit, and then the flue gas type lithium bromide ice water machine 1 can work.

[0036] In the above setting, during the operation of the flue gas type lithium bromide ice water machine 1, the coolant discharged into the flue gas type lithium bromide ice water machine 1 can be cooled down.

[0037] Specifically, the circulation pipeline 4 is provided with a liquid inlet part 41 and a liquid outlet part 42. The coolant in the cooling steel belt 5 can be discharged into the flue gas type lithium bromide ice water machine 1 through the liquid inlet part 41, and then the coolant that has been cooled down can be discharged into the cooling steel belt 5 through the liquid outlet part 42 for work.

[0038] Furthermore, a spraying part 51 and a liquid return part 52 are provided in the cooling steel belt 5. That is, the coolant conveyed through the liquid outlet part 42 enters the spraying part 51 in the cooling steel belt 5 after passing through the circulation pipeline 4. The spraying part 51 can discharge the coolant, thereby completing the cooling of the resin. After the coolant is sprayed out, it can continue to flow back to the liquid return part 52. The coolant in the liquid return part 52 can flow to the flue gas type lithium bromide ice water machine 1 through the circulation pipeline 4 and the liquid inlet part 41 to complete the cooling of the coolant.

[0039] In the above process, through the connection of the circulation pipeline 4, the flue gas type lithium bromide ice water machine 1 and the cooling steel belt 5, the circulation work of the coolant can be completed. Among them, the flue gas type lithium bromide ice water machine 1 uses the waste heat in the incinerator 2 as the heat source, thereby effectively reducing the cost of cooling the coolant.

[0040] In an alternative embodiment, resin is conveyed on the cooling steel belt 5. Preferably, the cooling steel belt 5 is connected to the reaction kettle for receiving the liquid resin in the reaction kettle. That is, the liquid resin in the reaction kettle is discharged onto the cooling steel belt 5 and cooled by the spraying part 51 on the cooling steel belt 5. The resin discharged on the cooling steel belt 5 will be cooled to a solid state and then conveyed to other systems for further processing.

[0041] In the above process, preferably, the temperature of the resin in the liquid state is 200 °C, and when the resin is discharged from the cooling steel belt 5, it is in a solid state, and the temperature of the solid resin is 40 °C. That is, the resin in the liquid state discharged from the reaction kettle is 200 °C, and the temperature of the solid resin discharged from the cooling steel belt 5 is 40 °C.

[0042] Since in the above process, the circulation pipeline 4 is connected to the flue gas type lithium bromide ice water machine 1 and the cooling steel belt 5, the circulation of the coolant can be continuously carried out, and thus the coolant can be continuously sprayed through the spraying part to cool the resin.

[0043] In the setting of the incinerator 2, preferably, the incinerator 2 includes a furnace chamber 21, a heat exchanger 22, a preheater 23 and a induced draft fan 24;

[0044] Among them, the furnace chamber 21 is communicated with the heat exchanger 22, the heat exchanger 22 is communicated with the preheater 23, the preheater 23 is communicated with the induced draft fan 24, and the flue gas is discharged into the flue gas type lithium bromide ice water machine 1 through the induced draft fan 24.

[0045] It can be understood that an induced draft fan 24 is provided in the incinerator 2 to guide and discharge the flue gas in the incinerator. The induced draft fan 24 is communicated with the flue gas type lithium bromide ice water machine 1, and thus the flue gas can be discharged into the flue gas type lithium bromide ice water machine 1, thereby providing a heat source for the flue gas type lithium bromide ice water machine 1.

[0046] The above setting can stably discharge the waste heat in the incinerator 2 into the flue gas type lithium bromide ice water machine 1, thereby improving the energy utilization rate and reducing the production cost.

[0047] In the above setting, preferably, the temperature of the flue gas discharged from the incinerator 2 is 230 °C, and the flue gas discharged from the flue gas type lithium bromide ice water machine 1 into the smoke exhaust part 3 is 110 °C. That is, the high-temperature flue gas is discharged from the incinerator 2, the temperature drops after passing through the flue gas type lithium bromide ice water machine 1, and then is discharged from the smoke exhaust part 3. It can be understood that the smoke exhaust part 3 can be set as a chimney.

[0048] In the above circulation process of the coolant, preferably, the temperature of the coolant discharged from the liquid inlet part into the flue gas type lithium bromide ice water machine 1 is 30 °C, and the temperature of the coolant discharged from the liquid outlet part into the cooling steel belt is 20 °C. In one embodiment, the temperature of the coolant discharged from the cooling steel belt 5 can be reduced through the circulation of the flue gas type lithium bromide ice water machine 1.

[0049] In an alternative embodiment, preferably, a plurality of spraying portions 51 are provided on the cooling steel belt 5, and the plurality of spraying portions 51 simultaneously spray and cool the resin. Those skilled in the art can arrange the plurality of spraying portions 51 to spray the coolant onto the resin, thereby continuously cooling the resin.

Certain industry standards or implementation schemes slightly modified on the basis of the implementation described by the custom method or embodiment can also achieve the same, equivalent or similar, or predictable implementation effects after deformation as the above embodiments. The embodiments of applying these modified or deformed data acquisition, processing, output, judgment methods, etc. still fall within the scope of the alternative implementation schemes of this application.

[0051] Although this application is depicted through embodiments, those of ordinary skill in the art know that this application has many deformations and changes without departing from the spirit of this application. It is hoped that the appended embodiments include these deformations and changes without departing from this application.
