Embodiment 2
[0062] Embodiment 2: A tail gas recovery and purification recycling device of an annealing furnace system, including an adsorption purification device, a circulating power device, a deaerator, a first cooler, a gas-water separator, an adsorption drying device, and a connection between each part Pipeline, the air inlet of the adsorption purification device is connected to the exhaust outlet of the annealing furnace, the air outlet of the adsorption purification device is connected to the circulating power device, and the air outlet of the circulating power device is sequentially connected after the deaerator Connected to the first cooler, the gas-water separator and the adsorption drying device, the air outlet of the adsorption drying device is connected to the air inlet of the annealing furnace through a pipeline, and the pipeline is provided with a first pressure regulating device.
[0063] In this embodiment, its structure is basically similar to that of the first embodiment. Th...
Embodiment 3
[0064] Example three: such as Figure 5 , 6 As shown, a tail gas recovery and purification recycling device of an annealing furnace system. In this embodiment, its structure is basically similar to that of the first embodiment. The difference lies in: the annealing furnace tail gas discharge port and the adsorption purification device 2 There is also a dust-removing and oil-collecting device 1 on the pipeline between them. The dust-removing and oil-collecting device 1 includes a front and a rear two-stage oil collector, a first-stage oil collector 11 and a second-stage oil collector 12, respectively. A cleaning port is provided, a cooling jacket is also provided on the outer wall of the oil collector, and bypass valves 13 are respectively provided on the inlet and outlet of the two-stage oil collector, such as Image 6 Shown. When working, the exhaust gas is blown into the oil collector in a direction tangential to the oil collector, and rotates along the inner wall of the oil c...
