A kind of operation principle of simple checking enrichment hot air apparatus of the utility model is：The air inlet straight tube of single group baking oven unit
15 and waste discharge bend pipe 14 access waste discharge manifold 25 so that baking oven not only took the hot wind with concentration from waste discharge manifold 25, but also will dry
Hot wind is discharged into waste discharge manifold 25 afterwards；Higher concentration near ink tank is collected by ground air draft pvc pipe 16, transparent wired hose 17
In VOCs gases and the ground air draft collecting pipe 18 being uniformly connected into below hot wind, it is sent in waste discharge manifold 25, it is attached ink tank can be collected
The VOCs gases of nearly higher concentration, improve print zone working environment；It is set close to one end of waste discharge manifold 25 on air draft gas collecting tube 18
It is equipped with air draft Electric air valve 19, by the air inflow of its adjustably air draft, while being pacified before ground air draft enters waste discharge manifold 25
Equipped with preheating heat exchanger 20, ground air draft can be preheating to certain temperature and then be given to the first color；Brand-new waste discharge manifold simultaneously will be each
The air inlet and waste discharge pipeline of color hot wind access manifold, install the inspection of LEL concentration additional before the rear end of waste discharge manifold enters waste discharge blower fan
Device 22 is surveyed, which can detect the concentration in waste discharge manifold in real time, negative to help commissioning staff to set pipeline
Pressure adjusts total waste discharge air quantity, and equipment waste discharge concentration is controlled always in 25%LEL or less.
One end of the remotely air draft gas collecting tubes 18 of waste discharge manifold 25 is also associated with frequency conversion waste discharge blower fan 23, frequency conversion waste discharge blower fan
23 frequency is adjusted by 21 detection data of B/P EGR Back Pressure Transducer EGR, and main function is to maintain the negative regulation of waste discharge manifold,
Specific waste discharge amount is determined by the impedance operator of whole system completely.It is mechanical in the installation of the outlet side of frequency conversion waste discharge blower fan 23 simultaneously
Check-valves 24, because the total exhaust duct in workshop is in barotropic state, if a certain printing machine is not powered on, the exhaust gas in pipeline will fall
Workshop is poured into, the outlet of frequency waste discharge blower fan 23 connects emission-control equipment, waste discharge is handled.
In view of the presence of the organic exhaust gas of high concentration near print zone ink tank, installs three for each print couple and carry
The ground air draft pvc pipe 16 of small sircle hole is separately mounted to above the left and right downside and ink tank of ink tank into before baking oven, then is used
Transparent wired hose 17 connects itself and ground air draft gas collecting tube 18, can be in a steady stream since gas collecting tube remains negative pressure state
Constantly the ground air draft of high concentration near print zone is collected in gas collecting tube, so as to improve the working environment of print zone.
Wherein it is per the effect of the air inlet check-valves 12 on blast pipe 2 of the same colour, when this color hot wind is not opened, waste discharge manifold 3
Interior negative pressure sucks workshop gas by wind turbine, enters the wind the one-way flow effect of check-valves 12 and the pass of motorized adjustment air-valve 13
Close and avoids the generation of such case；Motorized adjustment air-valve 13 on waste discharge bend pipe 14 to adjust the waste discharge amount of every color baking oven,
Baking oven is maintained at micro-vacuum state, baking oven is avoided to leak out to workshop or largely suck cold wind.
When the utility model is implemented, select hot wind direction for the direction of gradual enrichment, with a flexible package as shown in Figure 9
For 8 color printing machines, Soft Roll prints the first color and is printed for full version, and other colors are color version printing, and inking amount only has full version printing
10~20%, therefore the hot wind direction chosen is from last of the same colour to the gradual enrichment of the first color；If finally of the same colour is full version, should
The air inlet straight tube 15 and waste discharge bend pipe 14 of the baking oven of version do not access waste discharge manifold 25, and it is straight to carry out waste discharge according to original mode
Run in and carries out exhaust-gas treatment after giving up.
