Background technology
At present, the intaglio press that plastics package printing industry waste gas solvent recovering system is handled, the capacity of each printing element is 3000m
3/ h.The gross exhaust gas of one ten look printing machine is 30000m
3/ h, the voc gas content is at 1.5g/m in the exhaust
3About, belong to the toxic emission of typical low concentration atm number.The waste gas of handling the low concentration atm number need adopt absorption recovery system bulky and that treatment effeciency is lower.Because shortcomings such as the recovery system investment are big, and the investment payback time is long, the application of gas recovery system plastics package printing industry at home at present is confined to minority large enterprise.
Summary of the invention
Owing to the difference of printed patterns, the printing area of each printing element reaches as high as 100% in the plastics package printing, minimum possibility＜1%.The oven dry air quantity of existing printing machine drying system is fixed, and the voc concentration of oven dry emission gases can reach 8g/m when full plate prints
3About, and printing area hour voc concentration＜0.1g/m
3
If the oven dry emission gases discharge capacity of printing machine drying system can change according to the variation of printing area, when printing area hour just can reduce gas emissions, the voc concentration of raising emission gases.Realize reducing the exhaust-gas treatment amount of gas recovery system, improve organic efficiency.
The present invention is for solving the technical problem of waste gas solvent recovery; Provide a kind of printing machine with the device that improves concentration and decreasing emission of waste gas; The technical scheme of technical solution problem of the present invention is: the present invention is by, concentration detector, reclaim gas control valve, reclaim gas pipeline, circulation air path, control valve, benefit air channel, circulation heating blower, heater, drying baker, printing machine, air inlet duct, exhaust passage constitute.Its concrete technical scheme is: a side of printing machine is provided with drying baker; The top, exhaust passage of drying baker top one side is provided with concentration detector; Exhaust passage 12 is provided with the middle part of reclaiming gas pipeline 3 and reclaims gas control valve 2; The below, middle part of exhaust passage is provided with circulation air path, and circulation air path end place is provided with mends the air channel, mends air channel and circulation air path junction benefit wind control valve is set; Below, circulation air path middle part is provided with the circulation heating blower, and circulation heating blower air outlet is provided with heater, and heater and drying baker middle part are provided with air inlet duct.
Printing machine provided by the invention with the course of work of the device that improves concentration and decreasing emission of waste gas is: in original circulating air energy saver, increase gas concentration detector; Increase on the toxic emission pipeline and reclaim gas control valve; Increase on the air intake pipeline and mend the wind control valve, reclaim gas pipeline and form exhaust gas discharging control system.
Circulation heating blower and heater print film heat drying to passing through in the baking oven.When gas concentration is increased near the residual concentration that exceeds standard of printing, reclaim gas control valve adjustment discharge amount of exhaust gas, with toxic emission concentration, be controlled at the maximum concentration value that guarantees product quality and be lower than quick-fried point all the time.
Than hour minimum emissions of recovery gas control valve control waste gas, set up the subnormal ambient in the drying baker at printing area.
When printing area was big, discharge amount of exhaust gas increased thereupon, mend the wind control valve with the air quantity that increases mend into, keep the stable of negative pressure and bake out temperature in the drying baker.
Beneficial effect of the present invention:, can realize the minimizing of concentration maximization, discharge capacity of discharging waste gas through above technology.Reach and reduce the order ground that the exhaust treatment system treating capacity improves exhaust treatment system efficient.
