So set, by setting throttle valve control flow, so as to obtain good filter effect according to actual condition.

Further setting：The waste gas collection device with the air inlet pipe including connecting, the air-breathing above printing machine The exhaust fan for covering and being arranged in the air inlet pipe.

So set, starting exhaust fan, negative pressure is generated in air-suction cover, thus the exhaust gas and powder that are generated when printing machine is worked Dirt absorbs.

Further setting：The emission-control equipment is photodissociation catalytic converter, and air inlet connects the exhaust pipe, Exhaust outlet connects delivery pipe.

So set, exhaust gas enters photodissociation catalytic converter through exhaust pipe carries out purified treatment, gas passes through discharge later Pipe is discharged into outdoor, so as to fulfill the catharsis to exhaust gas.

Further setting：Drain tap is provided on the delivery pipe.

So set, by setting drain tap so as to adjust gas emissions according to the treating capacity of exhaust gas.

In summary：Start exhaust fan, negative pressure is generated in air-suction cover, thus the exhaust gas and powder that are generated when printing machine is worked Dirt absorbs；It after exhaust gas is absorbed by waste gas collection device, is passed through through air inlet pipe in the water of dust water tank, makes mixed dust in the offgas It is disconnected；Water body enters through drainpipe in filter later, and filter screen is by the dust catching in water body, so as to fulfill to dust Collection and water body purification；Exhaust gas enters photodissociation catalytic converter through exhaust pipe and carries out purified treatment, and gas passes through later Emission by exhaust pipe is to outdoor, so as to fulfill the catharsis to exhaust gas.
