[0022] refer to Figure 1 , Figure 2 and Figure 3 An air inlet 208 is provided on the left side of the cyclone separator 205, an air outlet 209 is provided on the top of the cyclone separator 205, a first exhaust pipe 3 is fixedly installed on the top of the first exhaust valve 206, a processing box 4 is fixedly installed on the right side of the first exhaust pipe 3, a coarse-effect filter 5 is fixedly installed in the inner cavity of the processing box 4, a medium-efficiency filter 6 is fixedly installed on the right side of the coarse-effect filter 5, a second exhaust valve 7 is fixedly installed on the right side of the processing box 4, a second exhaust pump 8 is fixedly installed on the top of the second exhaust valve 7, and a second exhaust pipe 9 is fixedly installed on the right side of the second exhaust valve 7.

[0023] The above scheme is adopted: through the setting of the coarse-effect filter 5, it is convenient to remove larger particles, fibers, etc. in the exhaust gas to protect subsequent equipment from being blocked and damaged by particles. Through the setting of the medium and high-efficiency filter 6, fine particles, dust, bacteria, viruses, odors, etc. in the exhaust gas can be removed, which can further improve the removal efficiency of particles in the exhaust gas, ensure that the exhaust gas emission meets environmental protection requirements, and reduce the impact on the environment and human health.

[0024] refer to Figure 1 , Figure 2 and Figure 4 An oxidation tank 10 is fixedly installed on the right side of the second exhaust pipe 9, a third exhaust valve 11 is fixedly installed on the top of the oxidation tank 10, a third exhaust pipe 12 is fixedly installed on the top of the third exhaust valve 11, a heat exchanger 13 is fixedly installed on the right side of the third exhaust pipe 12, an exhaust gas outlet 14 is opened on the top of the right side of the enameling machine drying furnace body 1, and a sealing ring 2010 is fixedly installed in the inner cavity of the suction hood 201.

[0025] The above scheme is adopted: through the setting of the heat exchanger 13, the heat energy in the exhaust gas can be transferred to other media to achieve energy recovery and utilization, which can reduce energy consumption and improve the energy utilization efficiency of the system. Through the setting of the sealing ring 2010, it is convenient to improve the airtightness of the suction hood 201 to prevent the exhaust gas from leaking into the air and polluting the environment.

[0026] Working principle:

[0027] When in use, an air suction hood 201 is installed at the exhaust gas outlet 14 of the main body 1 of the enameling machine oven, and the exhaust gas is guided to the pretreatment mechanism 2 through the air suction pipe 202. The particulate matter in the exhaust gas is separated from the airflow by the cyclone separator 205 using the principle of centrifugal force to achieve the removal and concentration of the particulate matter. After passing through the cyclone separator 205, the exhaust gas enters the treatment box 4 and is further filtered through the coarse filter 5. The coarse filter 5 removes the remaining larger particles and dust in the exhaust gas to protect the subsequent equipment from being blocked by the particles. The exhaust gas after the coarse filtration passes through the medium and high efficiency filter 6. The medium and high efficiency filter 6 uses finer filter materials to remove tiny particles, bacteria, odors and other harmful substances in the exhaust gas. Finally, the exhaust gas enters the heat exchanger 13. The heat exchanger 13 recovers the heat energy in the exhaust gas through heat exchange with other media (such as water, air, etc.) for heating or steam generation.

[0028] To sum up: this kind of waste gas recovery device at the outlet of the enameling machine furnace, through the coordinated use of the suction hood 201, the suction valve 203 and the cyclone separator 205, solves the problem that the waste gas at the outlet of the existing enameling machine furnace directly enters the filtering or reaction device, and the waste gas at the outlet of the furnace often contains particulate matter, such as dust, smoke, etc. If the particulate matter in the waste gas is not effectively separated, it may enter the subsequent waste gas treatment equipment or emission pipes, causing blockage, damage or reducing the treatment effect.
