The suction hood 21 guides the exhaust gas generated by the printing machine body 11 and introduces the exhaust gas into the suction pipe 22. The filtering mechanism 24 removes solid particulate impurities in the exhaust gas. The exhaust gas after impurities are removed is passed into the subsequent exhaust gas treatment equipment for centralized treatment, thereby completing the treatment of the exhaust gas generated by the printing machine body 11 when it is working, and reducing the probability of the exhaust gas floating in the working environment causing harm to the environment and human health.

The water is pumped into the return pipe 37 by the water pump 38 and guided back to the spray pipe 26 for subsequent spraying, thereby realizing the reuse of the water and reducing the consumption and waste of water resources.

[0055] The working principle of the embodiment of this application is as follows:

[0056] The fan 23 is started to exhaust air from the suction hood 21 through the suction pipe 22. The suction hood 21 guides the exhaust gas generated by the printing machine body 11 and introduces the exhaust gas into the suction pipe 22. When the exhaust gas in the suction pipe 22 passes through the filter box 25, the spray pipe 26 sprays the exhaust gas to remove impurities in the exhaust gas. The exhaust gas after impurities are removed enters the subsequent exhaust gas treatment equipment for treatment, thereby completing the treatment of the exhaust gas generated when the printing machine body 11 is working, and reducing the probability of the exhaust gas floating in the working environment causing harm to the environment and human health.
