Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5The utility model provides a technical solution: a dual-module energy-saving cooling and heat exchange unit, including a flue gas duct 1, thermal insulation cotton 2, a heat exchange tube 3, a heat exchange cylinder 4, an exhaust pipe 5, a processing box 6, an activated carbon purification net 7, a fixing plate 8, a sealing gasket 9, a smoke exhaust valve 10, a fixing mechanism 11, a support block 12, a movable column 13, a protrusion 14 and a fixing block 15.

[0030] When using the dual-module energy-saving cooling heat exchanger unit, Figure 1 and Figure 2 As shown, the flue gas pipe 1 is connected to the external boiler equipment, which is not shown in the figure. The outer surface of the flue gas pipe 1 is wrapped with heat insulation cotton 2. The setting of the heat insulation cotton 2 can play a role in heat preservation and prevent heat loss when transporting high-temperature flue gas. At the same time, the flue gas pipe 1 is connected to the heat exchange tube 3. The heat exchange cylinder 4 is provided with a proper amount of cold water. The water in the heat exchange cylinder 4 can be heated by the heat exchange tube 3 to achieve the effect of heat exchange and reuse. Moreover, the heat exchange tube 3 is spirally arranged in the heat exchange cylinder 4, thereby increasing the actual heat exchange area, greatly improving the actual heat exchange efficiency, and having high practicality.

[0031] The lower end of the heat exchange tube 3 is connected to the exhaust pipe 5, and the exhaust pipe 5 passes the flue gas after heat exchange into the treatment box 6, and the treatment box 6 is provided with an activated carbon purification net 7. Through the setting of the activated carbon purification net 7, the flue gas after heat exchange can be filtered and purified to prevent the flue gas from being directly discharged to the outside and causing pollution to the environment. After the filtration and purification is completed, it can be discharged to the outside through the exhaust valve 10. Figure 3 , Figure 4 and Figure 5 As shown, the activated carbon purification net 7 is fixedly connected to the middle of the fixing plate 8, and a sealing gasket 9 is provided between the fixing plate 8 and the processing box 6. The setting of the sealing gasket 9 can play a sealing role to prevent the smoke from leaking;

[0032] In addition, through the setting of the fixing mechanism 11, the fixing mechanism 11 includes a support block 12 fixedly connected to the upper right end of the fixing plate 8, a movable column 13 for connection, a protrusion 14 for positioning and a fixed block 15 fixedly connected to the right end of the processing box 6. After the heat exchange and filtering and purification treatment is completed, the movable column 13 can be rotated, and the movable column 13 can be rotated at the upper end of the support block 12. The torsion spring at the connection between the movable column 13 and the support block 12 undergoes elastic deformation. At this time, the movable column 13 drives the protrusion 14 to rotate, so that the protrusion 14 faces upward, and then the support block 12 is pulled to the right. The support block 12 drives the protrusion 14 to be pulled out of the fixed block 15 through the movable column 13. At the same time, the movable column 13 is disengaged from the fixed block 15, driving the fixed plate 8 to move to the right, and the fixed plate 8 drives the activated carbon purification net 7 to be moved out of the processing box 6, thereby facilitating the disassembly and cleaning of the activated carbon purification net 7 and the filtered impurities, and preventing the activated carbon purification net 7 from being blocked during long-term use.
