[0012] The present invention will be described in further detail below with reference to the examples of the drawings:

[0013] Such as figure 1 The circulating water device of the waste rubber cracking production line shown includes a cracking kettle. The cracking kettle has a kettle body 2 and a kettle cover 1 installed outside the kettle body 2. The kettle body 2 is mounted on the frame through hollow shaft frames arranged at both ends. The hollow shaft 2-1 at one end of the body 2 is communicated with the water-cooled air pipe 3 provided with an outer water jacket through the connecting pipe 3-3, and the water-cooled air pipe 3 is communicated with the air inlet of the primary cooler 4. The air outlet of the cooler 4 communicates with the air inlet of the secondary cooler 5 through a pipe; the air outlet of the secondary cooler 5 communicates with the air inlet of the primary oil separator 14 through a pipe, and the primary oil separator The gas outlet of 14 is communicated with the air inlet of the secondary oil and gas separator 13 through a pipeline; the oil outlets of the primary oil and gas separator 14 and the oil and gas separator 13 are respectively communicated with the oil storage tank 9 through oil pipes. The outer water jacket of the water-cooled air pipe 3 has a water inlet 3-1 and a water outlet 3-2, the primary cooler 4 has a water inlet 4-1 and a water outlet 4-2, and the secondary cooler 5 has an inlet. Water inlet 5-1 and water outlet 5-2; water inlet 3-1 of the outer water jacket of water-cooled air pipe 3, water inlet 4-1 of primary cooler 4 and water inlet 5-1 of secondary cooler 5, respectively It communicates with the water outlet 10-2 of the thermal refrigerator 10 through a water pipe, the water outlet 3-2 of the outer water jacket of the water-cooled air pipe 3, the water outlet 4-2 of the primary cooler 4, and the outlet of the secondary cooler 5. The water port 5-2 is respectively connected with the water inlet 10-4 of the thermal refrigerator 10 through the water pipe and the reservoir 6, and a water pump 7 is installed between the reservoir 6 and the water inlet 10-4 of the thermal refrigerator 10 and on the water pipe. . A first flue gas outlet 1-1 and a second flue gas outlet 1-2 are opened on the top of the kettle cover 1, and these two flue gas outlets are connected in series with the flue gas inlet 10-3 of the thermal refrigerator 10 The flue gas outlet 10-1 of the thermal refrigerating machine 10 is connected to the dust collector 8 and the chimney 12 through a pipe in turn. The duct between the dust collector 8 and the chimney 12 is equipped with an exhaust fan 11. Such as figure 2 The thermal refrigerator 10 shown includes a refrigerant tank 10-13, an evaporator 10-5, and a heater 10-8, a generator 10-10, a rectifier 10-9, and a condenser 10-7 that are connected in sequence; The evaporator 10-7 communicates with the evaporation tube of the evaporator 10-5 through the expansion valve 10-6. The evaporator 10-5 has a case and an evaporator tube installed in the case; the water inlet 10-4 and the water outlet of the thermal refrigerator 10 10-2 is on the cabinet with evaporator 10-5, the water inlet 10-4 is on the cabinet on the side of the evaporator outlet 10-5-2 of the evaporator 10-5, and the water outlet 10-2 is on the evaporator The inlet of the evaporator tube of 10-5 is on the chassis on the side 10-5-1; the evaporator tube of the evaporator 10-5 is connected to the refrigerant tank 10-13 through the vacuum pump 10-14; the refrigerant tank 10-13 is connected to the generator 10 -10 is equipped with an exchanger, the exchanger has a central tube 10-11-1 connecting the generator 10-10 and the refrigerant tank 10-13, and a jacket 10-11 set outside the central tube 10-11-1 The annular cavity surrounded by the central pipe 10-11-1; the refrigerant tank 10-13 is connected to the annular cavity of the exchanger and the heating pipe of the heater 10-8 through the circulating pump 10-12 in turn, and the heater 10-8 The front end of the heating pipe is provided with a pipe section with a spray head extending into the generator 10-10; the flue gas inlet 10-3 and the flue gas outlet 10-1 of the thermal energy refrigerator 10 are arranged on the heater 10-8 The heater 10-8 has a casing and a heating tube installed in the casing. The flue gas inlet 10-3 is installed on the casing on the side of the heating tube outlet 10-8-2 of the heater 10-8. The flue gas outlet The 10-1 is installed on the housing on the side of the heating pipe inlet 10-8-1 of the heater 10-8.
